KMC 3 - Will the USB charge my phone/tablet?

Yes, but NOTE that charging any device through the KMC 3’s USB input while the KMC 3 is running on battery power will significantly shorten battery life. We recommend only charging your device for a short time period and only when absolutely needed when the KMC 3 is on battery power.

The USB port on the KMC 3 will have an output of 5V DC/1A.
