A power bank that can be carried in a pocket is a useful little gadget that keeps your devices charged while you are out and about. Generally, it is constructed using aluminium or strong plastic, it is light in weight, the mass of the device being between 100–400g, and compact, the length being about 10–15cm and the thickness 2–3cm. Usually, it is black, silver, red, or any other color in those shades, with a nice smooth finish. Virtually, all of them show battery capacity through the LED indicators and feature a layer of rubber for comfortable holding.

Performance and Features

Portable chargers are really cool, they have power between 5,000 and even 20,000mAh and they can charge tablets or smartphones for several times. They are commonly equipped with fast charging (up to 20W via USB-C Power Delivery) and a few ports like USB-C and USB-A that make it possible to charge some devices simultaneously.

Besides, built-in safety functions such as overcharge protection ensure the safety of the customers. The quick charging of the power bank during travel is appreciated by users as it saves time but there are some that say larger-capacity models take a while to be fully recharged.
