Solar chargers for phones. Frequently asked questions about solar chargers. How does a solar charger work?

1.What is a solar charger?

Solar charger consists of several photocells that convert the sun's energy into direct electric current.
A modern solar charger has the ability to charge both phones and tablets, as well as netbooks, laptops and 12 V batteries.
At the moment, on today's market there are many different solar devices of varying power, battery capacity and solar panels from various manufacturers.

2.How does solar charger work?

If this solar charger with battery, then when sunlight hits the solar panel, they are converted into energy, thereby charging the built-in battery, and the battery charges the devices. If this solar battery without battery, Then the sun's rays hit the solar battery, are converted into energy and directly charge the devices.

3.What does solar charging consist of?

Solar charger with battery consists of a solar panel, built-in battery, charge/discharge controller, converter, clad in a metal or rubber case. Solar battery without battery consists of solar panels, a charge/discharge controller, and a converter, usually covered in waterproof fabric.

4.Which portable equipment can be charged using a solar charger?

The solar charger can charge:player, phone, smartphone, camera, tablet, netbook, laptop and other related devices.

5.What types of solar chargers are there?

There are 2 types of solar chargers: solar charging with a battery (capacity from 4000 mAh to 25000 mAh) and solar charging without a battery (solar panel power from 3 to 300 W). Also on the solar device market you can find a folding-type model, but with a battery - SP 8000 (5 Watt).

6.Can the solar charger be dropped?

A solar charger, like any other equipment, dropping is not recommended. Since even if the properties include shockproof, this means that there is less likelihood that in case of an accidental fall there will be damage or this will affect its technical condition, but does not exclude its failure.

7.Why do chargers with the same power have different prices?

This can happen if solar chargers are produced by different manufacturers, then the price is influenced by the material, build quality, actual battery capacity, pricing policy of the manufacturer and other properties, due to which the price may differ.

8.Why does the specified output current of 1 A and 2.1 A not always produce the maximum?

Output current may differ from specified, due to the fact that when charging the device, the current required for uniform charging is automatically selected and then it is automatically reduced during the charging period.

9.Can I do solar charging myself?

Make a quality solar device yourself practically impossible! There are no savings, because It has been proven from experience that in terms of the cost of all parts and accessories, a do-it-yourself solar charger is more expensive than one purchased in an online store. Yes, and the possibility of use, durability and The quality of the charge is also reduced to zero. Bottom line: if you want to have a good solar charger that will serve you for a long time, you can buy it in specialized stores that have a quality certificate and warranty.

10.How long can the built-in battery last?

Average number of complete charge/discharge cycles is about 1000, after this, the battery gradually begins to lose capacity, Over time, the battery capacity decreases by 15-20%. One cycle should be understood as a charge from 0 to 100%, i.e. If you do not charge and discharge the device completely, it will last many times longer.

11.If the solar charging ports do not indicate what their output current is, how can you determine this?

If the ports do not indicate what the output current is in the device, then as a rule there are other designations, for example: port A, port B, or 1 lightning symbol or 2 lightning symbols or port 1 and port 2 are drawn. In this case: port A, 1 lightning and port 1 - output current 1 A, and port B, 2 lightning and port 2 has output current 2.1 A.

12.Is the battery capacity indicated in the description always real?

In most cases, the capacity is real, however, some devices have lower power than declared (in our online store, in product reviews, the actual battery capacity is always indicated, after testing the solar device by our specialists). In addition, it is worth considering that in the process of charging devices: smartphones, tablets, laptops, natural losses occur, which may affect the reduction of battery capacity by 10-15%.

13.If one of the charging properties is waterproof, what does that mean?

This kind of solar charger is more than other chargers protected from water and moisture. Most often, it is encased in a rubber casing, which makes it more likely to protect components from water and moisture, but does not mean that it will completely protect the internal contents. if the charger gets exposed to heavy rain or gets wet in water.

14. Why does solar charging take a long time to charge from the sun?

If we take as an example the average chargers with a panel power of 1.2-1.5 W and an output of 200-300 mA, then the charging speed from the sun from a discharged state to a full charge will be about 25-40 hours. Unfortunately, it is almost impossible to increase the charging speed with such parameters and a pocket size, since faster charging requires a larger area, but then it will be difficult to fit it in a bag and take it with you everywhere.

There are several options for solving this issue:
1. You can connect a battery-free charger to the charger with a battery, which can charge it much faster, since it has a large area for absorbing rays (folding type). 2. Use such charging to compensate for discharge, and not for full charging.

15.What are the differences between polycrystalline and monocrystalline silicon?

The first difference is the appearance: The polycrystalline panel is blue, and the monocrystalline panel is black.
Second difference: efficiency of absorption and conversion of solar rays into energy. The efficiency of a polycrystalline panel 15-17% , and for monocrystalline 18-20%.

16.How many degrees can solar panels withstand?

Depending on the manufacturer and type of solar charger, the maximum temperature + 45 , minimum - 20 . There are special models designed for extreme climates, but such devices are usually made to order.

17.If there are 2 USB ports in the charger, is it possible to charge from them at the same time?

Yes, you can charge at the same time. With this device you can simultaneously charge two phones or a phone and a tablet.

18.What are the different ways to charge a solar device?

There are three options for charging a solar device: from a 220 V network, from a laptop USB port, from the sun.

19.How long does it take for a solar charger to charge from the sun?

Depending on the power of solar panels and battery capacity, from 12 to 50 hours.

20. How long can it take to charge various devices from a solar battery?

If we take the average statistical data, then telephone can be charged for 1.5-2 hours, tablet in 2-4 hours.

21.How to properly use the solar charger?

At the beginning of operation, it is necessary charge the battery completely from the mains, then during operation, for example, you recharge a mobile phone ( battery 2000 mAh), place the solar charger in the sun and it compensates for this discharge within 6-8 hours.

22.How do the principles of operation of solar chargers with batteries and without batteries differ?

Solar charger with battery Before use, you need to charge about 100% from the mains and then, after charging the devices, compensate for the selected capacity by charging from the sun.
Solar charger without battery has a different operating principle: to charge the device, you need to place the solar charger itself under the sun's rays and connect to it the device that you want to charge and thereby ensure the charging process.

23.How to properly store a solar device?

If you plan to not use the charger for a long time, more than 1 month, you need charge the built-in battery by 60-70% and store it at room temperature.

24. Is it possible to disassemble the solar charger and then use the cells to charge devices?

Solar charger categorically It is not recommended to disassemble , because In this case, you can damage the solar charging elements and the case; it is also not recommended to use the elements of the device, because a disassembled and damaged device is not intended for use. After disassembling the device, it will automatically is excluded from warranty.

25. How does the power of solar panels affect the charging of solar devices?

Charging speed of the built-in battery or connected devices directly depends on the power of solar panels. For example, if the panel has a power 1.5 W, then its current is 300 ma hours, if 5 W, then 900 ma, if 10 W, then 1500 ma. That is, to charge, for example, a smartphone with a 2000 battery from a 1.5 W solar panel, you will need 7-8 hours, from 5 W - 2.5 hours, 10 W approx. 1.5 hours.

As can be seen from the given data, solar chargers with panels up to 3 W suitable only for compensating for the discharge of the built-in battery, and from 3W Solar panels can be powerfully used for fast charging directly from the sun.

26. How effective is solar charging in cloudy weather?

The charging efficiency of devices in cloudy weather is very low - it drops from 20 to 70%.

For charging in cloudy and sunny weather, it is important to place the solar charger correctly! The solar charger should be placed according to the angle of incidence of the sun's rays. For example, if the sun is at its zenith, then the charger must be placed horizontally. The rest of the day is sunny, at an angle of about 40 degrees.

27. Which solar chargers are better made in China or the USA?

Almost all solar chargers are made in China, including those intended for sale in foreign markets (USA, Europe). Chinese companies such as RIPA, DBK are not inferior in quality to chargers for the American market (Opteka, Poweradd).

28.Is it necessary to overclock the battery or why is the battery capacity lower at the start of solar device operation?

Very often, due to the high capacity of solar batteries, they need to be “overclocked” a little so that they reach their actual capacity. To do this, it is recommended to completely discharge and charge them to 100% at the beginning of operation 3-4 times.

29. How to check if the solar panel is working?

If this is a solar panel without a battery, you need to unfold it and take it out into the open area (outside). Then, position it perpendicular to the sun so that the sun's rays fall directly on the entire area of the solar panel. After, you need to connect a suitable device for charging from the solar panel, for example a phone, and charging will begin.
If it is a model with a battery, you should also take it out into an open area where it will not be exposed to sunlight. nothing prevents, turn it towards the sun and the charge indicators will start flashing.

IT IS IMPORTANT! Checking the SOLAR Charger from daylight, in the room, on the balcony, from a flashlight, light bulb, fire etc. is considered invalid!

30. Is it possible to charge a laptop from a solar panel?

Yes, sure! There are solar panels that capable of charging a laptop. For a laptop, panels with a power of from 40 Watt and above . To understand how much solar panel power your laptop needs, you need to look at the indicated number of Watts on the power supply. This will be the minimum that your laptop needs.

31. How to charge a camera using solar charging?

It all depends on how you charge the camera. If it is charged via a USB port in everyday life, then almost any solar charging with USB output. Simply connect the camera using a cable and charging will begin.
If the camera is charged through removable batteries and a special socket for them, then you need solar panel with DC output!
If your camera is charged only from the network, then a set of a solar panel and a special external battery is suitable for you. with socket outlet. You're at home, charging your external battery and taking it and the solar panel with you. On a hike, for example, you charge your camera from it, and, if possible, recharge the external battery from a solar panel so that it is always charged if you need it.

32. How long does it take to charge a phone using a solar panel?

In time, the phone from the solar panel (solar panel power from 14 Watt and above) is charged in time, as from the mains (outlet).

33. Is it possible to charge a 12 V car battery from a solar panel?

Today there are solar panels with a port DC (12-18 V), from which you can charge a car or other 12 V battery. If you often go camping and need a car battery not discharged while the car is standing, the panel will be enough for you power 7-21 Watt. If you plan to charge your car battery from 0 to 100%, then you need a model more powerful 28-100 Watt.

34. How to test a solar battery without sun?

Without direct sunlight, check the actual performance of the solar panel impossible. All checks without sun are very relative and do not provide the correct output indicators.

35. Will the solar panel work through glass?

The operation of a solar panel through glass is possible, but it is not very effective, since the indicators are significantly reduced due to the refraction of sunlight by the glass. In addition, operability is only possible for large solar panels power 40 Watt and above, since due to their area they have enough sunlight to recharge the device. Also, to charge through glass, the battery must fit tightly to the glass and must be exposed to direct sunlight at the right angle!

36. How do solar panels work in cloudy weather?

Solar panel efficiency drops from 30 to 80% depending on the level of illumination (measured in lux). Powerful and large solar panels work better than smaller ones due to their area, which allows them to collect more solar energy.

Receiving energy from an inexhaustible natural source and converting it into electricity. Not so long ago, such a statement could only be found in science fiction books. But today, thanks to progressive technologies, people have learned to receive energy from the sun and use it to charge various devices. Such units are not yet very popular in the domestic market. However, it is possible that very soon charging with solar batteries will become a necessary attribute of a comfortable life.

Scope of application

What is a solar charger? This is a device with a simple design.

It consists of the following elements:

Converter;
Battery charge controller;
Battery.

Thanks to its extremely simple configuration, the solar-powered device is highly reliable and multifunctional.

Its operating principle is as follows: the rays falling on the solar panel are captured by it and converted into electricity. It is collected on the battery, but the rate of its accumulation depends on weather conditions and the power of the panel and is regulated by the battery charge controller.

Naturally, in cloudless weather the accumulation rate will be maximum, and in cloudy weather it will be minimum. As for the solar battery, it can have a power from 0.2 W to 3.5 W and when using the latter, the battery charging speed will be no more than 5 hours.

Let's watch the video, scope of application and subtleties of choosing a device:

In addition, portable solar chargers are equipped with a USB port for connecting various types of modern equipment to them. The output current can reach 2.1 A and such models are used for tablets.

On the solar charging body there is a charge indicator and an on/off button. Additionally, the package includes adapters for various phone models and a USB cable.

Types of solar chargers

The classification of this kind of gadgets is carried out according to several criteria. First of all, they differ in power. Moreover, solar battery chargers for phones and tablets are small in size and weight, which makes them convenient to use.

Powerful charging models using solar batteries have large dimensions, but since the area of their panels is quite large, the power significantly exceeds the values permissible for compact models.

Another difference is the location of the battery. It may be built-in or not. Elements of the first type are intended for mobile equipment.

Solar chargers without a built-in battery have a wider range of applications. They can provide energy for both mobile equipment and small TVs, refrigerators, and lighting devices.

A variety of adapters

There are differences in the type of battery itself. In chargers with solar panels, lithium-ion and lithium-polymer batteries are most often used. The latter are able to retain a charge for quite a long time and are characterized by the absence of a “memory effect”.

All the pros and cons of devices

The main advantage of such gadgets over conventional ones is the ability to use them in places where there are no electrical networks. Therefore, solar battery chargers are in greatest demand among outdoor enthusiasts, fishermen and extreme tourism enthusiasts.

Various shapes and types

But besides this, gadgets have a number of advantages, among which we should highlight:

Environmental safety;
Durability;
Does not require fuel;
They work silently;
The resulting energy is completely free.

But, like any device, a solar charger has some disadvantages. First of all, it is high cost and low efficiency. But still, it is not even these qualities that affect the purchasing power of the device, but such as low efficiency in bad weather and dependence on geographical location.

It is these parameters that most often have a decisive influence when purchasing a charger. However, we can say with confidence that this equipment is the future.

Device selection criteria

When hiking or fishing, there is often a need to power mobile phones or tablets. And if earlier it was almost impossible to solve this problem, today it has become possible thanks to the advent of portable devices that convert solar energy into electric current. But when choosing a charger, you need to take into account its output current and voltage, which depend on the characteristics of the battery.

But there is another aspect. Since solar panels can only operate during daylight hours, the chargers in which they are used must be equipped with a battery. It is he who will accumulate energy during the day and release it to your mobile equipment at any time of the day. However, keep in mind that for stable charging of a phone or tablet, it is necessary that the charger output have a voltage corresponding to this parameter of the equipment.

Watch a video about the Solar Charger P1100F-2600 model:

Often the device has additional functions, such as charging the battery from the mains using an adapter. The package may also include adapter kits for connecting devices that differ in model and manufacturer brand.

There are solar-powered chargers equipped with a USB connector, which allows you to connect any gadgets to them. All these parameters must be taken into account when choosing a specific charger, which will allow you to use it with maximum efficiency.

Review of popular models

Although there are quite a lot of chargers on the domestic market, only some of them are in demand. This is due to a variety of factors. One of the most popular is the Solar Charger P1100F-2600 model. It is designed for charging digital cameras and phones, as well as some other devices.

The device is equipped with a built-in lithium-ion battery with a capacity of 2600 mAh and a solar battery charge controller.

Watch a video about a high-capacity charger:

The charger is compact in size and light weight and is ideal for hiking and walking outside the city. The kit includes adapters for charging phones of various brands. The model range of devices of this brand is represented by samples with different battery capacities, on which the cost is directly dependent.

Simpler and cheaper models include devices made in China. They are equipped with batteries with a voltage of up to 5.5 V and a battery capacity of 600 mAh. Such devices are designed for use with mobile gadgets.

Model brand PETC S09

There are also samples on the market with large battery capacities and sizes. Naturally, they are more expensive. Although in terms of design they do not have any special differences. Such devices can be used to charge laptops, video or photo cameras, and mobile terminals.

The products of Chinese companies are also represented by models without batteries. These include devices of the PETC S08-2.6 brand. But such gadgets are inconvenient because they can only be used during the day and are not able to work at temperatures above 60°C.

Conclusion

Based on the information received, we can conclude that buying a solar-powered charger is an ideal option for travelers. They are compact in size, easy to use and you don’t have to pay for the electricity received.

Do you go hiking often or are you constantly on the move? In the hot summer, even the most notorious geek strives to get away from the concrete jungle - to the seas, oceans, and forests. Someone chooses a hotel and completely loses the hassle of maintaining themselves and their gadgets (sockets and showers are, after all, brilliant inventions). Well, we, lovers of wild nature and multi-day hikes, encounter a number of problems, one of which is the lack of sockets. But there is one difference between an advanced and resourceful user and an ordinary person - he will use the scorching sun for his own selfish purposes. How? Of course, charge your tablet or smartphone using solar-powered portable chargers!

But there are so many of them... From expensive branded ones to cheap ones. How to figure it out? What is the difference? What do customers praise? Read our review, we have selected for you the 5 best chargers for all occasions.

Pros of solar charging:

A paradise for those who like to save money - charge your gadgets without using sockets.
Quickly charge your gadget within 2-3 hours anywhere there is sun.
Quite low price and long service life (more than 5 years).

Disadvantages of chargers:

The size of most devices (especially those capable of charging large gadgets like a laptop) is large enough to be transported in a pocket. The minimum folded size of a large charger is ~20x15 cm. The power bank is definitely more convenient for transportation - 15x7 cm, without the need to unfold the device. Such a gadget will easily fit into your pocket along with a smartphone connected to it.
This type of charging is only effective in sunny weather and does not accumulate charge! This means there is a high chance of being left with discharged gadgets after sunset. This rule, of course, does not apply to power banks (external batteries).
The need to deploy some particularly large chargers to connect to your gadgets.

How to choose a portable solar charger or an external battery?

Let's now figure out what characteristics are necessary for “survival” in hot summer conditions. What should you pay attention to first?

Waterproof

Splashes of summer rain or a wet towel carelessly thrown nearby can kill any gadget, so the most important point is water resistance.

Compatible with various gadgets

An iPad, an Android smartphone, your favorite soap dish - and all with different interfaces. Carrying three different devices with you for recharging is not very convenient. Therefore, our choice is models with extended compatibility.

Compactness

You don't want to lug around a mini power plant, right? The more flexible, thin and ergonomic the charger, the better. Pay special attention to “flexible” models - such a device will not break if it falls to the ground.

Price

To save or not? The question is complex and depends on your financial capabilities. Our top list presents the best options in terms of price/quality ratio. In any case, it is hardly worth paying more than 2,000 rubles for an external battery, or more than 7,500 rubles for a solar charger for a laptop (although we will still consider one premium model below). But we also don’t recommend the no-name model for 300 rubles.

We have selected for you the 5 best models in different categories:

universal solar charger
powerful solar charger for laptop
External solar battery for phone
solar-powered charger in the form of a backpack.

The best universal solar charger

There are 2 models at a similar price competing for the title of best universal solar charger:

Solar Charger (Upgrade Version), CHOE 19W 2-Port Solar Phone Charger(power 19W), worth 3500 rub.
Anker 21W 2-Port USB Solar Charger– more powerful (21W) product for the price 4000 rub.

Both models combine all the necessary qualities and provide enough power to simultaneously charge two smartphones in a couple of hours. And despite the fact that the CHOE charger has less power, it is not inferior to the Anker 21W in solar energy conversion and also promises to convert up to 23% of the sun's energy into charge energy.

They won’t fit in a pocket, but they will feel comfortable in a backpack without taking up much space. Both models have 3 solar panels, which is enough for phones, but not enough for a laptop (the next model is for that).

As for compatibility, all the necessary interfaces are available. You can connect all modern mobile gadgets on both iOS and Android.

Thanks to the metal rings on the surface of each of these models, you won't need to stop and unfold them - you just need to attach the device to your backpack and catch the sun right on the go.

The best solar charger for a laptop

ALLPOWERS 28W Foldable Solar Panel Laptop Charger

Unfortunately, not all such devices have the power to charge large gadgets like a laptop, so we turn to a “larger” model. There are 8 panels here; produces 28 watts of power, which will be enough to fully charge a 5000 mA battery in a laptop in 3 hours. Smartphones and tablets - in about the same time. Of course, subject to sunny weather. It must be said that the dimensions are noticeable only when unfolded - when folded, the charger is a compact bag that can easily fit into a backpack. The kit includes a bunch of adapters that are compatible with all modern laptop models, so the question of compatibility automatically disappears. There is also an interface that allows you to charge mobile gadgets using micro-USB. Hence the rather high price tag. But let's face it - he's fair.

The only negative is susceptibility to climate change. It is highly not recommended to use the device in pouring rain or near a fire.

The best solar mobile charger for your smartphone or iPhone

Portable solar power bank

If you don’t want to carry a charging folder with you, but will only charge mobile gadgets, pay attention to this external acc. As you understand, the main difference between this model and the previous two is that it stores energy, and you can charge it not only during the day, but also at night.

Waterproof, with a rubber shockproof casing, weighing only 317g, easily fits into your pocket, with a built-in flashlight - isn't this the ideal battery for everyday use? Add in a price tag of 2,000 rubles and we get a pure must-have for any practical user. But you won’t be able to charge anything larger than a smartphone or tablet from such a baby.

The best solar charger in the form of a backpack

SunLabz® Solar Charger Backpack (7w) INCLUDING 10,000 mAh Power Bank and 1.8L Hydration Pack

And another indispensable companion for traveling through the stone and real jungle is a backpack with solar panels. It is not one of the largest in size, but a 14” laptop with a bunch of useful little things will fit. The 6W solar panel hides a pocket underneath where connected gadgets are located. It’s a small thing, but the question of “where to put it” is automatically resolved. All devices are connected via a micro-USB cable that produces 5V.

The backpack comes with a 10 mA power bank, which produces the same 5V, sufficient to charge all portable gadgets. The volume is enough for two full charging cycles of the smartphone. Unfortunately, the included drive does not have a protective casing or a carabiner for fastening. Also, a disadvantage for tall people, especially men, can be the size - such a backpack will look too comical on an oversized back. This thing is worth it~ 3500.

SOLSOL Solar Hat

And finally, we have prepared a bonus for you - a promising unusual solar charger in the shape of a fashionable cap for ~ 3500. A promising project appeared on Indiegogo in the spring of 2016, and now such a cap is widely available for sale. If classic power banks and solar panels are too boring and banal for you and you want not only a useful gadget, but also a stylish accessory, pay attention to SOLSOL. The visor of this cap will definitely not go unnoticed in the crowd.

The only thing that can raise doubts is the convenience of such a cap. Devices are connected to it using a micro-USB cable to a connector hidden in the back of the cap. Whether you carry a connected smartphone in your hands or find a long wire that will reach the nearest pocket is up to you. The visor produces a power of 1 50mA - 278mA - quite enough for a standard smartphone charging cycle (2-3 hours). There are no protruding parts inside the cap, only a wire connecting the solar panels to the USB output.

The manufacturer did not limit itself to one color, and Solar Hat is presented in five colors. The device definitely deserves attention - adherents of a “green” lifestyle will especially appreciate it. Well, if you show up to their party wearing such a cap, you will definitely find yourself in the center of attention.

Let's summarize everything using a comparison table:

Model	Model price	Size	durability	Laptop
Anker 21W		66x28	+	-
RAVPower 16W		63x230	+	-
Panel ALLPOWERS 28W

Surely you know that Europe and the USA are massively switching to renewable energy sources. This means they are building a lot of wind and solar power plants.

Conclusion

Now you know which solar powered external batteries you should pay attention to. Any of the gadgets presented should suit your needs. But do not forget that the solar battery of these accessories has a small area, and therefore it charges the battery extremely slowly. However, models have already begun to appear that can quickly gain a large capacity. In the future there will probably be more of them, and the price tag will decrease.

A phone charger powered by sunlight has long ceased to be a fantasy, thanks to progress that continues to advance by leaps and bounds. And we don't mind getting everything from him?

With charging powered by sunlight, people have the opportunity to uninterruptedly use not only their phones, but also other mobile gadgets. It can be freely purchased in specialized stores at an affordable price. The solar battery has a set of adapters, allowing you to charge the most common brands of mobile phones, as well as other mobile devices. Having it, you can safely leave civilization, but not lose touch with family and friends.

A solar battery for charging your phone will no longer allow you to find yourself in a situation in which every person has been more than once: you are waiting for a very important call or, on the contrary, you need to make it yourself, but the phone is switched off. The unique properties of the solar battery are provided by a built-in Li-Pol battery, which is constantly charged from the solar battery.

At home or in cloudy weather, you can charge it in the usual way by connecting it to a USB port or directly to the mains. The output voltage is adjustable, which will help charge various brands of mobile phones. If darkness finds you, the built-in LED flashlight will help.

Basically, the package of the main cell phone models includes:

Power adapter
Instructions
Phone adapters
Battery and solar panel.

Input voltage is 5 V and current is 1000 mA
Output voltage -5.5 V
Power – 0.4 W
Weight – 0.2 kg
Package size – 1190x740x400 mm

The kit includes a USB cable and a set of adapters for charging various phone models.

A solar battery will especially come in handy if you are going on a road trip or trip, on a business trip, fishing, etc.

The new product is certainly the best that manufacturers have offered so far.

Principle of operation

The operating principle of a solar battery is extremely simple. Attached to the front of the portable charger is a photocell that captures solar energy, generating current to charge the phone. If there is a built-in battery, it also charges it. And in the dark, the latter can be used to charge gadgets.

The main advantage of solar panels, which more than covers all the shortcomings (they also exist) - this is the lack of the need to have an outlet on hand to constantly charge your mobile phone. This charger has the most reliable and environmentally friendly source of energy - the Sun.

Now about the disadvantages: For freedom from the need to constantly charge the device and clean air, you have to pay for the size of the solar battery, which is larger than the gadget being charged. After all, in order to provide the required current, the area of the photocell must be appropriate. And the minimum panel dimensions are therefore usually -13x8x1 cm, i.e. more than any smartphone. Size is a problem, but not the main one, since there is another one - night and cloudy weather, when the phone will not be able to charge if the internal battery is low.

How to choose a solar battery

It is impossible to imagine everyday life today without a smartphone or telephone. A person’s life becomes complete when he can send SMS or make a call, listen to music or surf the web at any time. And if the phone dies and there is nowhere to charge it, it’s like a disaster.

It is difficult to imagine the state of a person who has been deprived of communication for a long time - the light, for example, has been turned off. There is only one way out - buy a solar battery.

Moreover, if a long power outage is expected, then you need to look for a device not only with an external battery, but also with a built-in battery. And for those who like to travel, they need more powerful charging. In a word, when choosing a solar charger, you need to pay attention to a combination of a number of characteristics (design, functionality, guaranteed compatibility, versatility).

Design, of course, is an important characteristic, but even it can be neglected in favor of functionality. Well, what is the size worth, for example, in comparison with battery capacity, charging time, etc.? If the charger turns out to be incompatible with your phone, it will just be wasted money as it will be useless. Versatility is akin to functionality.

Even if a universal solar battery for charging your phone costs more, it will be useful for all the devices you have. In addition, the built-in battery inside will make charging possible at night and in cloudy weather.
