After months using a simple 12v wall charger for my EVO, I ended up adding a simple constant current source to guarantee 1/10C charge and also a simple LED to guarantee the EVO is charging.

See http://docs.google.com/View?docid=ddmbp9v7_1gb3fnh for circuit and more detailed info.

By the way, none of the components are critical. You can use almost any PNP transistor, and the resistor values are not critical either, except the 8.2ohms resistor to guarantee 150mA constant current.
