[quote name='popaloo']Question on your Nyko chargers, are they the kinds that you can keep all your stuff docked indefinitely and it wont harm the batteries on the controllers?
If so that's be great.[/QUOTE]
The issue you're referring to is related to certain Wii accessories. PS3 controllers automatically shut of their batteries once they're fully charged. I bought a $4 "charging station" that's basically a cradle for two first-party PS3 controllers with two mini-USB male ends: I use my Wii to power it (b/c its USB ports are always powered) and my PS3 controllers are constantly on the cradle. I've been using the setup for several years and my PS3 controllers work as good as new, and are always charged.
In short: you can charge PS3 controllers via mini-USB by pretty much any means, so your choice of chargers boils down to appearance and convenience.
BTW, nice find, OP--in for one!
