A power bank (English: power bank) is a device used to enter electrical energy into a rechargeable battery without having to connect the device to an electrical outlet. This battery charger is classified as portable because it is different from a battery charger that must be connected to an electrical outlet. The power bank has a capacity for electrical energy so that when the power has been used up, the electrical energy must be re-charged by connecting the cable to an electrical outlet. This power bank is not only able to recharge the cell phone battery, but also can recharge the battery on other devices such as iPod, iPad, tablet, and other devices.
The way to use the power bank is to connect the device connector cable to the power bank. The connector cable that connects the device to the power bank on one end of the power bank cable is like a USB connector that plugs into the power bank and the other end is shaped to fit the customized device charger holder.
