[quote name='cheko']What exactly is the purpose of these things. I mean, isn't the ps3 controller battery built in and cant you just set your ps3 settings to auto turn off your controller when not in use for like 10-15 mins. ? I know i did, my controller auto shuts off when i'm not using it for a certain amount of minutes its in the ps3 settings.
Thanx anyways OP for the Deal, but i'm going to pass[/QUOTE]
These are rechargeable packs to attach directly to the controller and charge them "wirelessly". So instead of hooking the controller to your PS3 via USB while playing just hook this up and it'll charge while you continue to play. Granted I see little to no use for this, but I think some people may, especially those who's PS3s are far away from where they sit and rather not have a 10 or so foot long cord across the room.
