search for "BL-5J wall charger", I used mine long for charging this way. And still sometimes, because I got 3 batteries. Better than always clip some wires on (I used a regulated power supply and soldered wires behind the enclosure of the phone for a while^^)

A tip for changing batteries: if you change them fast enough (few seconds) when the phone is turned off, you're system time won't be lost
