Today, the popularity of external batteries is only increasing. Manufacturers of modern gadgets equip their products with high-power cameras and install a lot of useful applications in them.
As a result, battery depletion occurs at an accelerated rate. If it is not possible to use a power source, then the use of an external battery will be the only way out of the situation.
Criteria for choosing a portable charger
Reflecting which Power Bank to buy, one should compare the most important parameters of the models available in the assortment. As a rule, we are talking about the actual:
Having studied the information provided by the manufacturer, it is very likely to get a decent model.
The importance of this parameter is difficult to overestimate. However, its great importance does not yet indicate the quality of the battery. It is best to be guided by the following rule – the capacity of portable charging should be 2-3 times the capacity of the battery of the gadget. Buying a powerful device with increased dimensions is unlikely to be appropriate. Many unknown manufacturers indicate the values of 20,000, 30,000 and even 50,000 mAh on the models they produce. The reliability of such information should be called into question.
Considering the possibility of Power Bank to buy, you should think about the convenience of its further use and storage. The mass of a product with increased power can reach half a kilogram. Wearing it for a long time in the pocket of a jacket or trousers will not work, which means that you can not do without a backpack. The best option would be a device whose weight does not exceed 250 grams.
It is this parameter that will determine the charging speed of the electronic device. Owners of smartphones should opt for a battery with a current value of 1 A. For tablet users, this value should be doubled (up to 1.5–2 A). When buying a charge, you need to study the contents of the specification. The current values indicated on the Power Bank and the gadget should be identical. Manufacturers, as a rule, indicate this figure near the USB port.
Having decided to buy Power Bank, you need to make sure that it has sufficient mechanical strength. An excellent alternative to the product in a plastic case is the model in an aluminum shell. Combined models also exist on sale – in a metal case equipped with protective rubber pads.
Additional characteristics include the number of ports, for example, 2 or even 3. The presence of several outputs will make using the device more comfortable. Surely the owner of the gadget will come in handy and an LED flashlight that allows you to instantly detect the location of the connector. A rather useful function is the digital indicator, which with high accuracy will inform about the residual charge.
After weighing all these factors, you can buy a high-quality Power Bank at a very reasonable cost.
