Charging Tinyscreen+ and Battery

[editortom]

Hey Folks - So far, I have always recharged the Tinyscreen+ battery via my Mac's USB port.  Is it possible to use a wall wart with a microUSB plug instead?  I wondered if I could use the charger that I use with my Pi.  It puts out 5v at 1600 mA.  I believe the TS+ says it wants 200 mA.   Will that work?   Thanks.
