Volts, Amps and Watts Explained for Device Charging
Charging specifications can be confusing. A device adaptor may display several values for voltage, current and power. When a school or business connects dozens of devices inside one cart, these values become important for electrical safety, charging performance and cabinet design.What Are Volts?Voltage represents electrical potential. A simple comparison is water pressure inside a pipe — higher pressure can push water more strongly. In an electrical system, voltage provides the potential that drives current. Typical USB charging profiles may use different voltages depending on the...
