If you look down at the Bloog forums on p 30-1 you can see my discussion. There's a nifty 7 slot charger for the 808ds! Rosewill RHB-330 7-port USB hub from Newegg. One of the Bloog peeps suggested it. They also mentioned that Bloog bats lose power very slowly so in lieu of a PCC you can just take many batteries in one case to an event. I'm posting it here cause I WISH I knew about it earlier....
