Power Bank - definition
Power Bank is an electronic portable power supply that is used to charge electronic devices which run on DC power such as mobile phones, laptops, PDA, GPS, and other similar devices. Power Bank comes with various ratings; the most major rating among all is “Capacity”. It denotes how many times or how much charge can be transferred to the target devices. For example, the most common ratings of the power bank are 5,000mAh, 10,000mAh, and 20,000mAh. By observing these ratings we can determine how many times it can charge up the particular device. i.e.: If a smartphone’s battery capacity is 5,000mAh and if you use a 10,000mAh power bank then we can easily understand that the power bank can charge up the smartphone 2x times. Power banks come with dedicated USB 2.0, micro-USB, Type-C, or lightning ports or jacks. The power bank is a very handy and compact device that can be carried easily and be sued to charge up devices without having the power outlets or travel adapter. It is considered a lifesaver in times of emergency.
