Charge may refer to any of the following:
1. To charge an electronic device is to add power to the device's battery, allowing it to store the energy it needs to carry out its functions. Charging can be done using a cable, like an AC adapter or USB cable, or through wireless means, like a Qi pad.
When a device such as a smartphone or laptop computer is charging, a lightning bolt symbol may appear at the battery level icon. When a device without a screen is charging, it may be indicated by a blinking LED (light-emitting diode) near the charging port.
When the battery is full, it's said to be charged or fully charged.
2. When buying goods or services, you can charge the purchase to a credit or debit card as a method of payment. The charge to a debit card removes money from your bank account and transfer it to the merchant's account. The charge to a credit card adds to the amount you are required to pay to the credit card company, to reimburse them for borrowing their money.
