Here's my charging methods with KGO and eGo
batteries:
-Wall AC to USB adapter that comes with an eGo charger cable.
-Powered USB 4-port hub
-Apple iPhone white wall USB cube
-Barnes & Noble Nook Tablet (folding prongs) USB adapter.
-Amazon Basics 6' USB extension cable
-Energizer XPAL XP2000 pocket sized battery with USB port
At home I usually have the Nook charger with the extension cable near my desk and plug in either my Nook or the eGo charger to charge stuff.
At work I carry a mini wall USB adapter and have a small pouch in my bag to charge my phone, iPod and another eGo cable.
On the road I have my XP 2000 mini battery (I love this) and use that to charge anything needing charging.
Note that the Nook Tablet charger (and an iPad charger) will push out 2 amps vs. 1 for most other wall adapters. Circuitry in the eGo cable should bring it down to 420 mAh for the eGo. I haven't had an issue with any of my gadgets charging. I'm not an expert, just a guy who charges a bunch of gadgets who also has friends and co-workers ask him to charge their stuff too.
