What voltage is A USB charger?
5 volts
Most chargers are rated at 5 volts, but some are capable of pushing more voltage for a faster charge. For instance, 4.8A output provides the maximum output for 3 Android devices, but the only way to charge them faster is to increase the voltage. This will charge the device about 20% faster.
