Only one great one I have ever found - the one at NoSmokeVA.com (search for PCC and the $29.95 one is the PCC alone). This is for the short 180mah Joye 510
batteries and it will fit any manuals or autos (I recommend manual
batteries BTW).
Holds 2 batteries (one can be charging) and 6 other other items. The 6 other items can be atomizers, carts, or what I use - cartomizers, though you do need to remove one carto condom to fit the cartos in the holes. Try not to overfill your cartos since you don't want
juice dripping into the PCC.
The only others I have seen are the original metal sharp-edged one that only holds 3 things, and another plastic one but that one doesn't support any manual batteries.
If you have the Joye 510 mega xl, then the only choice I have seen is the 510 mega xl PCC which is the sharp-edged metal kind but designed for the longer mega xl batteries.
