There are a few different versions of the PS3 Quad Dock Charger, for instance there's one that's made to charge four PS3 controllers and at the same time. They have one that charges 4 Xbox controllers in a couple of different designs. The model reviewed here only covers the PS3 controller.
A charger like the PS3 Quad Dock Charger eliminates cables getting tangled also has only a single AC adapter which allows you to charge your controllers without having the game console turned on. What's also nice about the dock charger, is that it also acts like a stylish storage stand for your controllers. The unit itself is largely made of plastic, not exactly high design, but works great, looks great and fits anywhere.
It's also really cool how the two blue LED lights flash at the top of the dock when you're PS3 controllers are charging and there's also a red LED which lights up at the connection point which makes it look good. I purchased the turbo fire controller after a lot of researching because I was looking for a bigger PS3 controller so my hands would not cramp, I am delighted with the controller and all its features. At the moment I'm using rechargeable AA batteries so it doesn't really bother me, but unfortunately can't use it with the Quad dock. When buying Quad Dock make sure to go for one made by Sony there are a lot of rip offs out there. Amazon is probably the safest place to buy.
