Does each USB port provide 2.1A charging or is this the total power supplies?Updated a year ago

PlugBug Duo is a 2.1A (12W) charger, so this is the total power it can provide. If only one device is being charged via USB, use the top port (labeled “2.1”) for the fastest charge of your device. If two devices are being charged simultaneously, the power will be equally split between the usb ports (1 amp / 6 watts each).
