How to Charge a Cell Phone With a Computerby Kallie Johnson
A cell phone uses a rechargeable battery for power. In order to charge or recharge the battery, you must use a cell phone battery charger. There are different types of chargers, which use power from different sources, such as an electrical outlet charger, a cigarette power adapter or a USB phone charger. A USB phone charger allows the user to plug the phone into any USB port on a computer or laptop to recharge the phone.
Insert the USB plug from the charger into a USB port on a laptop or computer.
Plug the other end of the charger into the outlet on the phone. Once connected, the cell phone should indicate the battery is charging.
Unplug the charger from the phone and USB port once the phone indicates the battery is fully charged.
