Keep all of your Wii Remotes™ charged and ready to go with Nyko’s Charge Station Quad for Wii™. The Charge Station Quad includes 4 NiMH batteries, exclusively designed for the Wii Remote, and each providing up to 25 hours of play time each. Each battery is easily recharged by placing the Wii Remote in the charging dock. The charging dock conveniently plugs into any standard wall outlet, allowing for rapid recharging of all four batteries simultaneously. The Charge Station includes 4 differently colored custom battery covers with contact pass-through points so you can charge the batteries while they are still in the remote. Each battery cover is also rubberized for superior grip during intense gaming sessions. The Charge Station Quad matches the décor and styling of the Wii, and is perfect for parties, tournaments and family game play sessions.
Features:
  • Charge 4 Wii remotes simultaneously
  • Includes 4 rechargeable NiMH battery packs
  • LED Charge Indicator lights
  • Quad port rapid recharging dock
  • 6 foot power cable
  • Rubberized battery covers for superior gaming performance

So not only can you charge 4 controllers at one time but you also get four of Nyko's own NiMH rechargeable battery packs and four rubber battery covers to prevent any accidents. All in one package and great for Wii parties. However, this will set you back $50 and will be available sometime next month.
