Phones, tablets, laptops and other useful electronic gadgets have become part of our daily life. Thanks to convenient applications, they, on the one hand, seriously facilitate our existence and communication with the world. But, on the other hand, our life is also complicated by them. Thanks to devices, we constantly stay in touch through social networks, instant messengers and the Internet. In addition, you need to carefully monitor the gadget: do not lose it, protect it from viruses, water, dust, overheating, and be sure to charge it regularly.

Modern devices with a rich "filling" in the form of running applications are very quickly discharged. Unfortunately, it is not always possible to find a free socket, especially when traveling. In order to eliminate unpleasant situations, it is better to purchase a portable charger such as Power Bank in advance.

Battery selection criteria

What technical characteristics of the Power Bank device should I pay attention to? Take a look at the following basic parameters:

1. Capacity;

2. Current strength;

3. Number of USB ports;

4. Weight.

External battery capacity is expressed in milliamperes per hour, labeled as mAh. What should this indicator be equal to? Carefully study the characteristics of your gadgets, in particular, if you are purchasing a portable battery for your phone, then check what is the capacity of your phone's "native" battery. Experts recommend purchasing a portable device with a volume that is almost 2.5-3 times the parameter of the device being charged. For example, if your phone has a consumption of 1500 mAh, then for such a gadget it is better to take a battery of at least 3500-4000 mAh. Such a large range is associated with the fact that the manufacturer often indicates the nominal, but not the actual capacity of the battery.

Additionally, when choosing, you need to focus on the type of gadget for which you need an external battery. So, the minimum requirements (you can charge the device at least once) for a smartphone is a battery of at least 2500 mAh, for a regular tablet - 5000 mAh.

The voltage or current strength of the Power Bank is usually standard and is 1-2 amperes and is marked with the letter "A". The requirements for the energy storage can also be read in the descriptions for the gadget (smartphone, tablet, laptop). If you plan to charge two devices at the same time, or need charging for large equipment, then choose a 2A portable drive with several USB ports, including mini-USB. Usually the inputs are universal and suitable for all devices. The simplest Power Bank model, which is enough to charge a smartphone or phone, has 1 USB input at 1A.

As for the weight and material of the cover, the standard model of the drive has a weight of 250-300 grams and a stylish plastic case. But, if the manufacturer indicates a lower weight, then pay attention to how much this corresponds to the truth, since it may not take into account the weight of the device as a whole. How charged the Power Bank itself is can be estimated by looking at the LEDs. A fully charged portable device is characterized by solid LEDs.
