The charger that came with the ChatPC-Silk is the only charger that should be used. It is rated at 5 volts DC output at 2 amps and has a 1.7mm OD jack on it with the center pin as positive. The part number of the charger is TD009. If you use a different charger than the one that came with the ChatPC-Silk you may damage the ChatPC-Silk and the battery.
