Everybody is good, can you tell me the working voltage of a device for 5 v, working current is 500 ma (USB), if I gave him my phone adapter for power supply, the output is 5 v, 2 a,?? Will damage the equipment??

CodePudding user response:

Will not damage, the adapter output current capacity is greater than the electrical current needs, is safe; Although your adapter can output 2 a, but the actual output current how much is your decision, for constant voltage power supply electric appliances, drain current does not exceed the appliance need current,
