Engadget just had an article about the charging chip in the 920 and its match in the fatboy pillow and other new Nokia chargers. They stated they provide 4x charging speed when paired. Im not buying anything else...
I'm planning on getting a charging pad that supports 2 or more devices for the living room (my gf and brother will also have 920s), two charging stands for the bedroom end tables and a charging pad for my desk at work.... Assuming the price is right for these things.
I say for the price, the dual energizer pad is a pretty good choice. The Nokia stand is good too b/c of the NFC possibilities.
Glad I bought 2 of the dual energizer pads while they were $19.99 on Amazon. something told me to buy more, but I just didnt feel like it. I might give 1 away as a gift which leaves me with only 1. I knew with the Nokia 920 release, the price would get bumped up once the hype built.
