Yea I remember back when mike brought up the idea, somewhere I had posted about making an adapter, (like the 510-510 one that you have to use in order to charge an ego/tornado battery) then one day mike made it and I wanted to buy one so I could use my chuck which I love the way It looks better than my buzz, (it's an all black matte finish) but since I already had a buzz and due to all the misfires I have had with my chuck I figured I'd just use the money on juice and cartos instead. But the infinity is a different story, lol, I brought that as a back up (mostly due to dead batts, case after all the abuse my buzz has taken already and still works fine I'm sure that it won't be the buzz that breaks) and I also brought that for when I go out, I can use something a little more sleeker instead of having people freak out when I pull my buzz out thinking it's a silencer for a gun, cause that's just what it looks like. But thanks for the advise, I just keep it in a safe place incase I REALLY need a backup for a few days, even if it's at 6v
