Review on Rechargeable Battery Packs and Charger for Wii & Wii U Remote Controllers, Motion Plus Controllers (Dual Charging Station Dock + 2 Pack 2800mAh Wii Replacement Batteries + USB Cable) by Nazrul Boscan

DO NOT BUY! It's just a cheap piece of plastic that may or may not charge your Wii remotes. Unfortunately that doesn't work for me. It starts normally and after 5 minutes all lights go off and then flash and go off. You cannot charge more than one as this will disable charging of the others. You're lucky if you can even fully charge one of these. And it's quite annoying because now I have to buy batteries and a charger for it.
