Hello everyone, I just ordered this PCC Electronic Cigarette Portable Charging Case (PCC) for 510 ONE Model Electronic Cigarettes | eCig PCC | Wholesale Electronic Cigarettes for my buddy who used 510 style batteries. The PCC plugs in and charges up, but when he screws in the battery and holds down the button it does not indicate that it is charging. I now see they call it a 510 "one" charger. Does that mean the polarity is reversed or the threads are different? Is there ANYWAY to get this thing to work for my buddies joye 510s?
