Power bank charger characteristics. How can you charge a power bank using different methods? Portable Power Bank - price

A power bank is a device used to charge gadgets when there is no power supply. Their connection occurs via a wire connected through the built-in USB port. However, in order to give charge to other devices, the Power Bank itself must first be charged.

Basic ways to charge Power Bank

About to purchase this device, you should ask how to charge this specific model and how to use it correctly. Despite the ease of operation, any model may have some differences and nuances. In order for the device to last a long time, you need to learn how to properly charge a portable Charger Power Bank, looking at the instructions.

From a 220V outlet

The main question that interests buyers is whether it is possible to charge a power bank using electricity, because this charging method is the most convenient and familiar. To do this you will need to purchase network adapter- it must be purchased separately, included in the package Power Bank he doesn't come in.

Because the external battery Designed for smartphones, it is logical to use a telephone charger for charging from the network. Given that the standard charging time for an external battery with a capacity of 4000 mah - 5000 mah is 4-5 hours, it is most convenient to plug it into the network at night. Charging from the network is much faster than via a USB port.

From computer via USB

The simplest option that makes it convenient for every user to charge a Power Bank is a computer. To do this, you just need to connect it to a working device using a cable via a USB connector. Charging occurs during its operation unnoticed by the owner.

From the energy of the sun

Many users are interested in whether it is possible to charge a power bank in the sun. This is the most economical and inexpensive way - you just need to place the device in the sun. However, it is only suitable for those external batteries that have a solar panel.

From car cigarette lighter and other devices

Users are interested in the question of whether it is possible to charge from an outlet in the car. Car enthusiasts who have a cigarette lighter in their car can charge the Power Bank while the car is moving. Another charging method is from a mobile phone. Appeared on the market mobile gadgets, performing the role of, among other things, an external battery.

How do you know if the external battery is charged?

How do you know if the power bank is charged? Standard device has 4 divisions indicating the amount of charge - 25%, 50%, 75%, 100%. The last indicator blinks when the battery is fully charged. However, the simplest budget models may have one or two indicators. When fully charged, the system will turn off the device automatically - there is no need to monitor the charge.

How long does it take to charge a Power Bank?

The time directly depends on two factors: battery capacity and charging method. The standard 5000 mAh capacity when connected to the network will require 5 hours to be fully saturated. If the capacity is twice as large, the time required for charging will also increase. Other methods are much longer, find out how long you need to charge a power bank from a computer or car cigarette lighter only possible through experience. The solar-powered device takes the longest to take energy out of thin air.

Features of Power Bank charging

The device must be charged until it is fully, 100% charged. However, when this indicator is reached, you should not rush to turn it off - experts recommend leaving it on for about another hour. At this time, “drip charging” occurs with a weak current, allowing you to maintain maximum capacity batteries for as long as possible.

You can track drip charging if you install an application specially created for this purpose - for Android and Apple.

Fully charge after purchase

There are different opinions on how best to charge a power bank after purchase. Some users claim that this moment doesn't matter. Manufacturers recommend that the purchased external charger, regardless of its charge level when purchased, be charged to 100%. It is important not to ignore drip charging.

Several charge/discharge cycles at the beginning of operation

When purchasing a Power Bank, you need to “boost” the battery - completely discharge and charge the battery. The same technique can be used if there is a faster than usual discharge.

3 or 4 full cycles of discharging and charging can rewrite the battery statistics.

Always charge your external battery to 100%

Users and manufacturers unanimously claim that modern Li-Ion batteries are devoid of the previous disadvantage - the memory effect. However, experience shows that this effect still exists, although less pronounced than with other types of batteries. Therefore, charging an external battery can be interrupted only in the most extreme cases, and in other cases, wait until the charge is completely 100% and withstand the period of trickle charging.

Why can't you completely discharge the battery?

However, it is not recommended to completely discharge the device to zero constantly - this will shorten the battery life.

You need to charge the battery when the charge level drops to 10-20% charge.

Depending on the model, this can be recognized by the indicators, seen on the screen, or determined by eye using the LED indication.

Sometimes it needs to be discharged

If you do not use the battery for a long time, then...

If you do not plan to use the external charger for a long time, it should be left to “rest” half charged. Full charging and discharging will negatively affect the service life.

Use original chargers

What kind of charger should I use to charge the Power Bank - any or a special one? It is extremely important to use original chargers for this device!

If this is not possible, it is important to choose those that match the characteristics of the Power Bank. Buying cheap accessories can result in expensive gadget repairs.

Avoid overheating the device

It cannot be charged under direct sun rays(except models with solar battery). You also need to make sure that it does not lie on the battery or running gadgets, or near a heating radiator.

In order for the Power Bank to serve for a long time, it is important to ensure that it does not overheat.

Conclusion

It is important not to use Power Bank in the cold - low temperatures significantly reduce battery capacity. Subject to all operating rules, the external charger can serve its owner long term, for example, such famous manufacturers like Xiaomi, Yoobao, Pineng provide a guarantee of 500 cycles, which equates to 7-8 years of active use.

As the performance of mobile devices increases, so do their power demands. A standard one or a smartphone can keep the gadget operational for 2-3 days under average load conditions. Obviously, this will not be enough if you are planning a week-long trip to nature or a trip where there may not be a possibility of recharging. For such cases there are special devices called powerbank - a portable charger that has a large capacity to power the same smartphones, tablets, cameras, etc.

What is a powerbank?

Externally, such devices resemble the same handsets of mobile phones. The standard form factor is a small cylinder or rectangle in which the working filling is located. Plastic or metal is used as the shell. The second option for finishing the case increases strength, and the first makes the design of the powerbank easier. A portable charger of this type only differs in appearance from the usual ones. mobile batteries, but it is made according to the same principles. As a rule, the filling consists of a Li-ion element, characterized by its small size and fairly high capacity.

At the same time, there are different versions such storage devices. The standard design is one that allows you to charge tablets and smartphones at home via a USB interface. But there are also special modifications, which include the D-Lex Powerbank model - portable starter-charger, intended for use in a car. This drive It is powered by a 12 V car power supply and, thanks to two USB outputs, allows you to charge mobile gadgets. This model is also distinguished by the presence of a flashlight and impact-resistant plastic in the body. If we talk about functionality, then with the help of D-Lex the driver can also start the engine.

Main characteristics

When choosing battery storage devices, two performance indicators should be taken into account - the capacity itself and the charging current. To begin with, it is worth considering the capacity, which on average ranges from 10,000 to 20,000 thousand mAh. For example, one of the best representatives of the segment, the device Xiaomi Power Bank modification of Mi, provides the user with 16,000 mAh. But here we must take into account that dividing the capacitive potential by the volume of the target battery will not give an idea of the complete replenishment cycles of the battery. To understand the actual service capability mobile device, for example, it is necessary to cut off about 30-40% of the resulting capacity.

As for the current strength, on average it is 0.5-3 A. Lower level optimal for modest consumers in the form of low-power phones, smartphones and flashlights. A tablet or a high-performance camera may require 3 A. It is advisable to follow the recommendations of the device manufacturer and select a power bank for this value. with inappropriate current strength can also perform its task, but energy efficiency this process will be lowered.

Models from Xiaomi

This manufacturer is a leader in the segment, successfully competing with market giants in Apple and Samsung. Although Chinese developers do not offer anything fundamentally new, releasing completely traditional and already standardized solutions. The simplest Xiaomi product from this family can be called a 5000 mAh modification. This drive has modest dimensions of 12.5x5.9x1 cm and a light weight of 156 grams. That is, the device is smaller than many of today's smartphones. What’s also important is that the 5000 mAh Xiaomi Power Bank has flat batteries provided with modern surge protection. User interaction with the device is facilitated by an LED charge level indicator. If we talk about the shortcomings, then we can safely include only one single USB port.

GP Powerbank series models

Quite an unusual line, the representatives of which cannot be called full-fledged powerbank devices. GP models are rather in the intermediate niche between battery storage and chargers. Such devices are designed to replenish the charge in batteries and some versions of batteries separately from the phone. In this case, the GP Powerbank device itself must be connected to a 220 V outlet during servicing. Fundamental difference from full-fledged drives lies in the absence of the possibility of autonomous charging via USB. Nevertheless, such devices also find application. In particular, the GP PB420 modification allows you to simultaneously charge 4 AA and AAA nickel-metal hydride batteries.

Model with solar panels Solar PowerBank

Connection idea solar generators has been mastering mobile consumers for a long time largest companies, but on the path of each concept in one form or another there are always stopping factors that do not allow launching mass production. Nevertheless, the Solar PowerBank device with a solar battery has made significant progress in this direction, offering users new approach to energy supply.

This is an external storage battery that does not require a 220 V outlet to power it. The device’s 20,000 mAh capacity is replenished by solar energy, which makes the device practically free to maintain. But there are also disadvantages to such powerbank models. The portable charger can only be charged with energy in good weather and in summer. The rest of the time you will have to contact standard system filling the container from the outlet.

User manual

To start working with the drive, you need to connect the target device to USB interface. The process of filling with energy will start automatically. The current status of the battery being serviced will be indicated by the indicator on the drive display. Again, do not forget that the socket for performing this procedure is in in this case not required since the powerbank is a portable charger. How to charge multiple batteries with different amperages? As a rule, models that provide several USB outputs, each circuit is supplied with a current of varying strength. A common example of a three-channel device is a configuration with 1, 2, and 3 A ports.

Conclusion

Despite the obvious benefits of portable drives of this type, using them as universal assistants is not always convenient. After all, this means that along with the same smartphone you will have to carry an auxiliary charging unit. Particularly impractical in this regard is a power bank with a solar battery, which, thanks to the accumulation panels, is rather large in size and also requires being outdoors. And yet there are cases when it is impossible to do without an additional and independent source of energy. This can be not only long trips or trips out of town, but also excessive loads on the smartphone on weekdays, when the charge runs out within a few hours.
