wandering if i can charge my x2 and my spinner batt with my volt wall charger? i know i can plug my x2 and my spinner cables into the wall adapter charger that came with my reguler volt batts....so can i charge them that way or is the wattage or voltage different or/and will it damage my x2 or my spinners...? i ask this because i dont always have my PC on and it would be easier sometimes if i could just charge using a wall charger...THANKS A BUNCH !!!
