How to choose a portable battery for your phone. Portable chargers: prices and reviews

Along with increasing the functionality and productivity of mobile phones, the requirements for power elements are also increasing. A typical battery is capable of operating the device for 2-3 days, but if the operation involves activity in social networks, the use of multimedia and frequent conversations, then it is possible to expect discharge in the next few hours. And carrying a charger is not always convenient - it's not just a matter of searching for a cherished outlet, but also of being attached to it as such. The optimal solution to the problem can be a portable battery for mobile phones, also called Power Bank. Such accessories also deliver certain troubles, but with them the user still gets some autonomy.

Select by capacity

At the first acquaintance with the characteristics of external charge inexperienced user can be fascinated by the huge capacity of such devices. For example, there are models that have a volume of 10 400 mAh. It would seem that this arsenal is enough for 5 sessions of replenishing the energy of the mobile phone, the battery of which contains 2 000 mAh. In fact, everything is not so simple. The fact is that the portable battery for the phone has a nominal voltage of 3.7 watts. In turn, mobile devices are charged at 5 V. This difference leads to a loss in the volume of the energy potential to 30%. And this is in the best case, since cheap Chinese models do not provide more than half of the declared volume.

But still rely on official data - it all depends on the brand of the manufacturer, based on the reliability of which you should make a discount in real energy. By the way, if a portable battery for a phone is purchased with the purpose of emergency maintenance of the device for a short period of time, then there is no need for a large capacity and you can confine yourself to a compact but high-quality and reliable accessory.

Selection by current strength

For most users of mobile devices that are dependent on the power supply, the indicator of the speed of the charge is also important. This characteristic is determined by the current strength, which is measured in Amperes (A). Usually, phones and smartphones are charged at 1A, and more demanding tablets require 2A. On these indicators, and should be guided by choosing a portable battery. Power Bank, by the way, can be equipped with two outputs - 1A and 2A. As a rule, such models have a decent volume - at least 7 800 mAh. Such devices, of course, and are more expensive, so you may think about using an external battery with one output to serve different devices. But such a decision is inconvenient and risky, since a mismatch in terms of current strength is harmful to the phone. And this is not to say that the charging process itself will take longer in the case of the tablet.

Purchase Power Bank without battery

For the most economical it is worth recommending the purchase of a separate Power Bank casing and battery. This option is beneficial for the reason that you can initially be sure of the reliability and characteristics of the battery. In turn, Power Bank will act only as a shell of the battery, providing interaction with the phone. True, there are disadvantages to such a decision. The fact is that a portable battery for the phone in this case will work on a weak outgoing current. Therefore, it takes more time to charge. On the other hand, the owner will be able to change the battery to another, while retaining the main Power Bank.

Manufacturers and prices

The importance of the quality of the charger has been noted more than once. In many respects reliability, durability and operational properties of external power supplies are determined by the manufacturer. As experts say, the greatest confidence is caused by Korean models from LG and Samsung. Usually the sellers themselves do not hide the accessories of the batteries to these brands. If in the marking the manufacturer is not indicated at all or a little-known company appears in it, it is better to refuse the purchase. Also worth mentioning are manufacturers who specialize in developing such devices. You can safely choose a portable external battery from the rulers Melkco, YooBao or Momax. As for prices, they are quite accessible to the average user of a modern phone. Models with a capacity of 10 000 mAh usually cost 1,5-2 thousand rubles. Buying an option for 5 000 mAh, you can even meet the price of 1 thousand rubles. And these prices, by the way, refer to models of firm origin.

External battery reviews

Despite the fact that the user of a modern mobile device already has to use 2-3 additional accessories, there are not so many ergonomics in handling external charges. Here it is necessary to note the merits of the manufacturers themselves, which give devices a stylish design and user-friendly interfaces. But there is criticism about the amount of energy that a portable battery provides. Reviews often point out the discrepancy between the actual figures claimed. But, as already noted, the official data should be oriented only with an adjustment due to the difference in stresses.

Conclusion

The practice of using shows that external chargers make life easier for busy people. Such devices are independent from the socket and require only connection to the target gadget. In terms of performance, of course, a lot depends on the manufacturer. For example, a portable battery for a phone from Xiaomi Mi with a capacity of 10 400 mAh can save the owner of the smartphone from searching the power grid for a whole week, subject to active operation. Such devices are also good in that they have a modest size and stylish design - even budget lines contain versions with an original appearance. Perhaps the most attractive options in this regard are an aluminum case that gives the device a solid look and protects the contents from external influences.
