The shape doesn't matter. The mini USB fits the HTC usb plug both for PC connections and charging. The HTC plug has an extra pair for earphones/mic for telephony and music. Don't use that anymore since the sprint TP2 has the 3.5 mm jack. There is a difference between usb and wall charging. On the daydeal cradle, the charging is from the wall charger even while connected to the PC and I get charged in an hour max. The extra battery does only charge from the wall charger, but since I leave both plugged in all the time, it doesn't matter. I have never had the problem that mxcrowe describes. USB is slower (lower current capacity from the PC USB bus) but I'll always get to 100%.
