USB doesn't automatically deliver maximum power to whatever is plugged into it. The client device has to ask for it. The default 5v 500mA isn't going to hurt anybody.
- gsich 7y agoNeither is 5V 2A, but that's more to skin resistance that's really high at such low voltages.
- magduf 7y ago5V at 1000A is completely safe too. The only thing that matters with electrical safety is voltage, and anything under 50V is generally safe for humans, all because of skin resistance.
