Which company should I buy an external battery for my phone? How to choose a portable battery for your phone. Portable chargers: prices and reviews

If you are lost among the array of offers for external batteries, this top power bank can help you weed out doubts and settle on a specific model. Almost every modern person already has a mobile gadget - be it a smartphone or a tablet, a laptop. These devices are portable and can be carried anywhere. However, the main difficulty with each such device is battery life. Unfortunately, even with all modern technologies, we have not yet learned how to create a battery that is tiny in physical size for a flat, stylish smartphone - manufacturers are still limited by the size of the device. So if you are an active person in life who does not sit at home, the problem of recharging your device is very relevant. And until recently, it was solved only by planning your route: from outlet to outlet. Travelers suffered especially - they had to buy very bulky devices, or overpay for an additional removable battery, or spend “cosmic” money on innovative specialized developments of solar batteries - all in order to power their gadgets without access to electricity.

With the advent of power banks and external batteries, as they say, life got better. There are a lot of interesting batteries on the market, and to make it easier to navigate, we offer our list of the best power banks.

Pros of the model:

• two USB outputs;
• large capacity;
• rough texture of the plastic case.

• decent weight, but nothing can be done about it;
• The modest appearance can be considered a disadvantage, but this is a stretch.

The main reason for the emergence of portable USB power banks was the increasing use of mobile technology, the energy level of the built-in batteries lasts for less time - on average half a day or a day. Every year new smartphones and phablets enter the market, with larger diagonals, richer screen brightness, increased performance, support for even more sensors, while the battery remains the same capacity. A large screen with high resolution and high pixel density (PPI), a touchscreen with a wide diagonal are the main factors for high power consumption and rapid discharge of a smartphone. To charge such gadgets in the absence of a wired power network, portable external batteries power banks were developed.

In the modern world, going on a business trip or traveling, going on vacation - to nature, fishing or hunting - is not complete without a portable power bank charger. In the absence of an electrical outlet, as well as other sources of energy, a portable power bank becomes indispensable for uninterrupted communication for a long time; with it, you don’t have to worry that watching a movie in the evening or communicating on social networks will leave your power-hungry smartphone or phablet without energy.

The average weight of a portable external battery is 150-300 grams, and the capacity is 2500-30000 mAh; compact models can recharge a smartphone once or twice, and the use of capacious portable USB power banks will restore the smartphone battery up to 10-20 times. Most models of external USB power banks are equipped with a full-size USB port and come with a USB-MicroUSB cable; external batteries with a USB Type C connector are also available. Top-capacity portable power banks can also be equipped with adapters for charging laptops. Often, for convenience, a power level indicator is additionally placed on the front panel of a portable powerbank, and an LED flashlight is also built-in.

Operating principle of a portable power bank charger

A portable power bank charger will easily restore the energy of a connected gadget to the required level when the mobile device’s own battery is low. A universal power bank charger is equipped with one or more batteries connected to a controller board, which also has connectors for charging the portable power bank itself and connected mobile equipment.

The service life of a portable power bank charger directly depends on the quality of the batteries and materials used in its composition: the higher quality components used in production, the more reliable its design and the longer the portable power bank charger will please the owner. Also, the operating mode of the universal power source has a significant impact on the lifespan.

• do not allow deep discharge of the battery (this can lead to its complete failure);
• charge only with currents not higher than those indicated on the power bank (energy recovery with high currents leads to a shortening of the battery life cycle);
• do not charge and try not to use at low or high temperatures (in such conditions the capacity, operating time and efficiency are reduced).

Thus, when choosing a universal external USB battery, we strongly advise against choosing the cheapest models - there is a risk of purchasing a low-quality device. Cheap USB power banks may contain poorly assembled elements and low-quality parts, which can cause the gadget to fail prematurely.

Features, differences and characteristics of power bank

Portable power banks are available in various sizes, with a variety of designs, design features, but are evaluated and differ according to the main characteristics:

• current when charging connected devices (output current);

Let's consider these features, differences and characteristics of the power bank in more detail.

Selecting external battery capacity

The capacity of an external power bank battery is the most important characteristic, showing how long the power bank can be a source of energy for connected equipment. Simply put, it shows the number of times a portable additional battery will allow you to recharge a connected gadget using its own energy. Capacity is measured in milliamp-hours (mAh).

When choosing the capacity of a universal portable external battery, we recommend following the rule: it should be selected 2 – 2.5 times larger than the size of the battery of the device being charged. For example, when choosing a power bank for iPhone 7, whose built-in battery capacity is 1960 mAh, we recommend purchasing an additional battery for iPhone with a capacity of 4000-5000 mAh - this is enough for one or two full recharges, so as not to be left without communication during regular use iPhone.

It should also be taken into account that the actual capacity of universal external USB batteries, indicated by the manufacturer, is given taking into account the voltage of the built-in batteries of 3.7 volts. And when a mobile gadget is connected to a portable energy source, current is transmitted with a voltage of 5 volts. Mobile equipment uses batteries with a voltage of 3.7 V. Thus, during charging, a double voltage conversion occurs: first, the power bank from 3.7 V to 5 V and then the connected device from 5 V to 3.7-4.2 V, the losses during this conversion are 20- thirty%. For example, if you charge a tablet with a battery with a capacity of 10,000 mAh with a portable charging power bank with the same battery, then the energy of the external USB battery will be enough to restore the phablet’s battery only by 70-75%.

The best choice of an external power bank for a budget smartphone would be a compact power bank with a capacity of 5000-10000 mAh, it is small, will allow you to comfortably use the device for several days, and can be carried in your pocket or small bag. Users of high-performance smartphones and tablets usually purchase a power bank for a smartphone with a capacity of 10,000 - 20,000 mAh. For long business trips, hikes, trips or travel, powerful power banks with a capacity of 20,000 - 30,000 mAh are better suited.

Current when charging connected devices (output current)

Current strength is measured in Amperes (A) and is considered the main indicator characterizing the efficiency of charging an external battery. The output current shows how quickly the connected equipment will be recharged. Portable batteries use a USB connector with an output of 1 A and a USB connector of 1.5 - 2 A for more demanding tablets.

• up to 1 A - cell phones (not smartphones), wireless headphones, bracelets, and other accessories;
• 1–1.5 A - most smartphones, GPS navigators, portable recorders and other autonomous devices;
• 2–2.4 A - smartphones with high-capacity batteries and tablet PCs.

The speed of energy replenishment is also affected by the charge controller of the connected device, which will limit the current strength if it exceeds that specified by the manufacturer. For example, the Sony Xperia Z3 smartphone has a 1.5 A limit set in the controller: when this smartphone is connected to an external portable battery with a 1 A and 1.5 A port, the current will not be limited, and when connected to a port with a current of more than 1.5 amperes, the smartphone will still consume no more than 1.5 A. The restrictions are different for each gadget; in some rare cases (often on cheap Chinese equipment) there is no protection at all, so we highly recommend not connecting to powerful ports without first checking compatibility. The easiest way to check compatibility is by looking at the specifications of the device being charged or at the charger supplied with it - if the current strength on the supplied charger matches the output current strength at the external battery port (or slightly exceeds it - by 0.1-0.5 A) , then you can safely charge your mobile equipment with an external battery power bank. For example, iPhones are equipped with a 1 A charger, and Apple iPad tablets come with more powerful 2 A chargers. Therefore, we recommend charging the iPhone with a universal external battery for iPhone with a 1 A port, and with iPad tablets it is better to use an external battery for iPad with a 2 A port .

For owners of modern gadgets with a capacious battery, we recommend choosing a universal external battery with fast charging and a current of at least 2 A, since the connected device will be charged slowly with a portable power bank with a lower current (or not at all if the device being charged is constantly used).

To find out the current strength before purchasing a universal portable battery, you should look at the markings next to the USB port - 90% of external power banks have information there. Some universal external batteries for mobile devices are equipped with support for Quick Charge technology. Such additional batteries are capable of charging a connected device with increased voltage but reduced current, so it is possible to charge a smartphone battery to 50–60% in just 30–40 minutes (if the smartphone supports QC technology).

Power bank charging current (input current)

The universal power bank is charged using the microUSB connector located on its body or, in the latest models, the more modern USB Type C connector. The rate at which a portable portable battery can recover its energy level depends on the voltage and current when it is connected to a power source. The current strength is influenced by two factors:

• what current can the charger supply;
• how much current can the powerbank consume.

To charge the battery of a USB power bank, we recommend purchasing network (SZU) or car (ASU) chargers for 1-2 A. Such a charger is enough to completely and quickly replenish the energy of a universal powerbank charger. It should be taken into account that external power banks have different maximum input current and it is better to select a charger taking into account this characteristic. Some models of external batteries with fast charging support the Quick Charge function, which allows you to recharge them with increased voltage much faster.

LED flashlight. A useful option that helps you easily find your way in the dark or during a power outage. When choosing a large, powerful power bank for long trips, hikes and frequent trips, the presence of this function is highly desirable. A power bank model with a flashlight is preferable to one without it - an LED flashlight can help out at an unexpected moment;

Second USB connector. In capacious external power supplies, the presence of a second USB port is also highly desirable and will allow you to charge two devices at the same time. In addition, in batteries with two USB outputs and increased current at the output of the second port, it is possible to quickly charge powerful devices, for example, an Apple iPad phablet;

Charging an external battery from the network. By default, power bank batteries are charged from a computer or laptop via a USB port, but if you charge them in this way, it will take a lot of time, so it is preferable to have the ability to restore the energy of an external USB battery using a charger (connected to the AC mains), which will allow you to quickly restore capacity;

Charge indicator. Shows information about the remaining energy level of the external power bank. Displaying the remaining level is a useful function, since knowing it in advance, a fully charged power bank with a charge indicator will help you avoid getting into trouble in a difficult situation - being left with a seated smartphone and a discharged portable power source;

The battery activation button is recessed into the body. A useful feature that helps avoid accidentally turning on or off the external backup battery;

Availability of solar panel. The option will be useful for those who like to travel, hike in nature or go to the mountains - in all cases when it is not possible to charge even a portable power bank for a long time. Thanks to the presence of a solar panel, it is possible to recharge a portable battery using sunlight, but it is worth noting that the efficiency of solar panels is 12-25% and recovery by solar energy will be slow.

The need for one or another additional function in a portable power source depends on the use case. Among the most useful functions, we recommend looking at the presence of a charge level indicator(will help avoid unpleasant situations), flashlight(will help you out at any time) and second USB port for capacious powerful power banks when using multiple devices. It is also worth considering that the presence of each option increases the price of the portable power source.

Such additional energy sources do not need to be charged frequently - the large capacity allows you to replenish the power of other gadgets for a long time. We advise you to choose.

What do all tablets and smartphones have in common, no matter how advanced and modern they are? This is the weakest point - constantly insufficient battery life and battery discharge at the most inopportune moment.

Even prudent users who leave home only with a 100 percent battery charge cannot cope with this “Achilles heel”. An unexpected situation may arise, a delay on the road or at work, after which you will be cut off from the world. A portable external battery can save the situation.

There are thousands of them on the modern market: from outright junk to very reliable and serious devices. Let's figure out exactly how you need to choose an external battery that will fully meet your needs and meet the stated performance. As a bonus, we will look at the best external portable batteries of 2017 on the domestic market.

Choosing an external battery: what and how?

A little educational program on power bank

An external battery, also known as a power bank, also known as an additional or portable battery, is a small portable battery that can be used to charge a number of devices: e-books, cameras, tablets, smartphones and others that receive energy using a USB cable.

This battery must be periodically charged from a computer or outlet, and it can store the accumulated energy for a long time. This allows you to take a power bank on a trip, to study or work - it will save you precisely when there is no access to electricity and an outlet.

Several batteries are located inside the external battery. They are connected to the controller board. This board contains connectors for connecting devices. By using the universal USB 2.0 interface, compatibility with most mobile devices is achieved.

Power banks can have any color, size and shape - here manufacturers delight users with a wide variety of options to make it beautiful and functional. You can buy a power bank with a plastic, metal or polycarbonate body. In terms of practicality, these options are the same, only in metal cases the batteries are heavier.

The greater the weight of the battery, the higher its capacity. Do not purchase models that have 20,000 mAh in the parameters and weigh approximately 100 g. If you need to use your smartphone while charging from an external battery, then it is better to choose the most convenient and ergonomic battery.

If the battery is needed only to hold out the time for normal charging, then you should choose a compact model that is light in weight. Some of them even have a keychain format.

It is appropriate to mention battery cases here. In fact, they are the same external battery with identical functions. There is a significant drawback here - it is intended only for a specific smartphone model. There is little practicality in such a solution, so you won’t be able to charge other gadgets.

External battery battery type: Li-pol and Li-ion

Often, users who are wondering which power bank is better discount the power of the battery used and are only distracted by other indicators. The functionality and durability of the device will depend on the parameters of the batteries used.

Modern power banks have one of two fundamentally different types of batteries:

• Lithium polymer Li-pol. A category of plastic batteries that can be manufactured into any shape. They outperform Li-ion in almost all respects: less self-discharge, lower losses, discharge/charge cycles for this battery from 1000 to 5000. All this affects its cost.
• Lithium-ion Li-ion. They differ in the shape of AA batteries. With identical dimensions to Li-pol they are more compact. This is not a particularly durable and cheap option, which will last approximately 1000 charge/discharge cycles. These batteries have higher energy loss and self-discharge, and they heat up more.

The most important indicator is battery capacity

Everyone who is planning to purchase a power bank first looks at its capacity indicator. This battery characteristic is the most important. She demonstrates what equipment and how many times it can be recharged. There is no need to chase record high performance; first you need to decide on the application scenario:

• If you need an external battery to charge your smartphone, and you rarely go on long hikes or business trips, then you can safely take a “can” that does not have a very high capacity. Thanks to this, the gadget will be light and compact. A universal formula is used to calculate the required battery capacity: the battery capacity is multiplied by 2 - 2.5 so that the device can be charged a couple of times. For a smartphone with a 3000 mAh battery, an external battery of 6000 – 8000 mAh is suitable.
• To discharge the tablet, you need to choose batteries with a capacity of 10–20 thousand mAh. This device will weigh approximately 350 – 400g, so be prepared for some extra weight in your bag.
• The largest power bank is necessary for charging various equipment or in cases when you are without access to an outlet for a long time. In this case, it is better to choose a more powerful external battery, from 10 thousand mAh. There are even miracle batteries with a capacity of more than 20 thousand mAh, but these products are for tourists who spend a long time away from civilization. These devices are equipped with adapters for charging a laptop.

There is no point in taking a power bank with a capacity of less than 4 - 5 thousand mAh, and in terms of cost there will not be much savings.

Manufacturers may slightly exaggerate the actual battery capacity. Little-known Chinese companies are often guilty of this. There are cases when a lightweight case claims a capacity of 58 thousand mAh. When purchasing an external battery in a store, you can use a special USB battery power tester to check the indicated numbers. This tester is sold for 2 - 3 dollars in Chinese online stores.

It is important to remember that the manufacturer reports the value of the battery capacity taking into account the voltage of the built-in batteries used at 3.7 V. When the gadget is connected, the energy is transmitted with a voltage of 5 V, and then again converted to supply the phone with a value of 3.7 - 4.2 V. Due to the double conversion, part of the energy is lost, and in some cases losses can be 20 - 30%.

Don’t be upset if a 10,000 mAh external battery will only charge a tablet with an identical capacity by 70–80%. At the moment, this is a cost of technology and a completely normal value.

The second important indicator is current strength

If you don’t go into technical aspects and details, the higher the current value, the faster the gadget will be charged from an external battery. When choosing a power bank, it is necessary to clarify with what current value you can charge your tablet or smartphone so as not to harm the device. This information should be on the supplied charger.

• It is undesirable to take up to 1 A, but you still need to try to find such a battery. Such batteries are suitable for charging simple phones.
• 1 – 1.5 A – this is an ideal option for charging most modern smartphones. If the current value is lower, the charging process will be irritatingly slow. If you charge a smartphone with a sufficiently capacious battery, which will also be used in parallel, then you may not see an increase in charging percentage at all. There is a limit to everything: it is better not to connect a smartphone to a 2 A port unless you are sure that this will not damage the device.
• 2 – 4 A – option for tablets. If you need to more or less quickly charge your tablet from a power bank, then you can safely take a portable battery of at least 2 A.

There are smartphone models that have a charge controller that limits the current. For example, the Sony Xperia Z3 is limited by 1.5 A, and if you connect it to a battery with a 3 A connector, the current will be limited, and the smartphone will still receive only 1.5 A. These safety measures are provided by the manufacturer.

The implementation includes external batteries that support fast charging. If you use it, the voltage increases and the current decreases. This ensures that the smartphone is charged 50–60% in 30–40 minutes. The exact data depends on which phone power bank is used in a particular case.

Due to improper storage and transportation conditions of the battery, its actual capacity may be reduced.

Number of ports

Power banks often have one USB port, sometimes there are two, and models with three or more outputs are rare. According to many users, multiple ports are considered a necessary thing.

It is necessary to choose a portable battery with several USB ports if you have a large number of gadgets and you are sure that there will often be situations when you have to charge them at the same time.

A power bank with several outputs and a small capacity will be of no use at all. There is no point in paying attention to such models. If the external battery has several ports, then they can be used normally with a capacity of at least 10,000 mAh.

One more nuance stands out. In theory, different ports are designed to simultaneously charge a tablet and a smartphone, so the manufacturer often supplies them with different current strengths (1 A and 2 A).

The 2 A figure is achieved when only one device is charged. Therefore, if you connect two gadgets at the same time, most likely, two ports will only provide 1 A each.

How is the power bank charged?

While charging your gadgets, the portable battery loses energy. It is also subject to the process of self-discharge. If you do not use the battery, it will lose approximately 5% of its charge in two weeks. Over time, the battery capacity decreases, especially if the gadget is actively used: in 1 year, a high-quality product loses about 15% of its capacity, and cheap models even 35%.

To monitor the charge level, these batteries are equipped with special LED indicators consisting of 3-4 light bulbs. The most advanced option is to use a small display, where the exact charge state of the battery will be displayed as a percentage.

Portable batteries according to the charging method are divided into the following groups:

• Powered only from a computer USB port.
• Receiving energy from the computer and from the network by connecting to a regular outlet.

Naturally, the second option is the most convenient. That is why the first type of batteries has almost completely disappeared from sale. Remember that charging the product from a computer takes much longer, and using the USB Type-C interface can speed up the process. Some portable batteries charge in record time due to the special fast charging feature.

An interesting option was charging using solar cells. It is too early to say that solar energy will become a full-fledged source for powering the external battery. Now solar panels are installed on the end of the device to compensate for self-discharge.

You can pay attention to a power bank with a built-in flashlight. They will come in handy when hiking or when there is a power outage.

Most portable gadgets have a micro-USB interface, and manufacturers often provide products with a universal cord. Owners of Apple gadgets and outdated equipment will benefit from models with universal adapters. Most users may not worry. They will be able to use the charging cord that comes with the smartphone.

Articles and Lifehacks

Each of us is familiar with the problem of a low phone battery. After all, no power means no phone. Therefore, when choosing a phone, it is very important to know the characteristics of the battery, because it depends on which battery is better how long you will be in touch, be able to listen to music or just play games and use the Internet.

There are two important criteria that you should ask the seller about first: type and capacity. There are still some nuances that should be taken into account when purchasing, and among them are the power consumption of the phone and how often and for what, besides talking, you will use your mobile phone. Let's look at the types of batteries in phones.

Pros and cons of different types of phone batteries

NiMH. Nickel metal hydride Batteries today can be called somewhat outdated. In modern phone models, this type of battery is no longer used, although it has its advantages, the most significant of which are large capacity and low price.

But, along with this, there are very noticeable disadvantages - the large size of the mobile phone and one very unpleasant need to completely discharge the battery from time to time so that later, when charging, it can gain full power again. In addition, this type of battery requires a long time to charge.

Typically, such batteries are used for cheap mobile phones with a basic set of functions, and if you are not particularly concerned about the appearance of your mobile phone, then this option may well suit you.

Li-ion Lithium-ion batteries are very popular and are used in modern mobile phones, although they are more expensive than nickel-metal hydride batteries, because they have undeniable advantages, including compactness, low weight and, at the same time, high energy density. In addition, this type of battery is better because it does not require any additional maintenance, such as complete discharge.

Of course, there are disadvantages here too. It is very undesirable to store such a battery in a discharged state. Use at low temperatures is also not recommended. And, unfortunately, this type of battery is subject to aging even when it is not used. Therefore, after some time it will need to be replaced. Another disadvantage is the high price, so it is better to purchase this battery if you have financial freedom.

Li-Pol. Lithium polymer batteries are a new stage in the development of lithium technologies. , such batteries were not even thought about. Probably the biggest advantage of these batteries is that their production technology makes it possible to produce batteries of different shapes and volumes. They can be very thin and compact. The cost will also please you - it is lower than the cost of lithium-ion batteries, and with all these advantages, such batteries have high energy capacity. This type of battery is used for a line of phones from.

Another thing worth considering when buying a mobile phone: the operating time indicated in the phone's characteristics is usually overestimated, because it is indicated taking into account the minimum load. It is also worth paying attention to the fact that the battery life is affected by the type of phone display, keyboard backlighting, and even the use of a vibration signal. Try to take into account all these nuances and, I hope, your use of the phone will bring you many pleasant minutes. Long and interesting conversations to you.

Today it is difficult to imagine the life of a modern person without smartphones, tablets and other battery-powered gadgets. And they all require recharging, and at the most inopportune moment, and even more so when traveling. To choose the best option, the Marka.guru portal suggests paying attention to the best external batteries included in the current rating. They will certainly come in handy if they are at hand at the right time, when the battery charge is at a critical level. But in order not to make a mistake when buying, you need to know a little about what is important in such devices.

So, what is the basis of external batteries, and what selection criteria can be called the most important.
• Capacity. Naturally, this is the most important parameter, how many devices can be charged or how many times it can be done. If 3000 mAh is enough for smartphones, then for a tablet you will need about 10,000. If you buy a device with 10,000 mAh, then it will be enough for 3 full cycles for a smartphone and only 1 for a tablet. Therefore, for such powerful devices it is worth choosing batteries with a capacity of up to 30 mAh.
• Current strength. The speed of the charging process depends on it. Conventional devices have a rating from 1 to 3 A. If we are talking about a tablet, then it is better to give preference to options with 4 A.
• Self-dischargeable. Over time, even the best battery loses its charge level. During 2 weeks of waiting, the level may decrease by approximately 5%. And with active use, this percentage increases, like the battery of any other device. Over the course of a year, this range can range from 15% for a well-designed device to 35% for budget models.
• Multiport blocks. Their convenience is that you can charge several devices at once, sometimes this can be a big help.
• Housing material. Presentable metal models attract the eye and are quite tactilely pleasant, but the durability and quality of work of the case will definitely not be affected in any way. Aluminum can be very scratched, and plastic can crack, so it’s better to immediately buy a case and treat the device with some respect.
