"When it's time to charge your device's battery, connect a Lightning to USB cable to its Lightning port, then connect the other end of the cable to your Mac or a USB power adapter."
I'm taking that as a yes and charging mine right now with an iPad 2.4A 12W USB Wall Charger Model PPMGN03.
In 3 minutes it charged the Magic Mouse 2 battery from 0% to 9%. So that's a confirmed yes, you can :)
