A power bank is a compact charger that is a battery for powering a smartphone, laptop or other gadget. Power Bank allows you to always stay in touch, recharging electronic devices in time.
At the heart of powerbanks are batteries of a certain capacity. They can be lithium polymer or lithium ion. When buying an external battery for a phone or laptop, it is better to choose Li-Pol devices — they do not discharge for a long time and do not heat up during prolonged use.
When the power of the Power Bank drops, it must be charged in the same way as any other electronic device — with a standard power supply with a microUSB or Type‑C cable.
What parameters to consider when buying a power bank?
To understand which external battery is better to buy, consider the technical specifications:
- capacity. The main parameter of a portable device. For a smartphone, a 10–20 thousand mAh device is suitable, and for a laptop it is better to look for at least 30 thousand mAh. There are also compact models with 3000–5000 mAh that allow you to charge smart watches, wireless headphones and phones;
- charging current. For most small gadgets (smartphones, smart watches), 2 A is enough, and for laptops, at least 3 A is required;
- connection connectors. USB A (standard USB) is in almost every external battery — third-party gadgets are connected to it. To charge the power bank itself, micro USB and Type‑C are usually used. External batteries for laptops are additionally equipped with adapters for different power sockets;
- frame. It can be made of metal, plastic, polycarbonate or anodized aluminum.
Some manufacturers also indicate the charging power. It depends on the current and voltage. The higher the power, the faster the device connected to the power bank charges. Also, this time is affected by the battery capacity of the gadget.
