Mobee Technology bills its Magic Bar as "a greener way to use your Apple Bluetooth Keyboard and Magic Trackpad."
That's because it allows you to replace the two standard AA batteries that typically power Apple's two popular computer accessories with a rechargeable cylindrical battery pack that gives you about 10 days of usage time.
Mobee says it all takes a minute to set up -- and it does. Just pop out your existing batteries, slide the battery pack in, and screw it into place (the screw-on cap that holds the standard batteries in their bay is no longer needed, but you'll probably want to keep it in a safe place). No extra tools are required. Just your hands.
The main piece of the Magic Bar is the "base station" that connects via USB to your computer and serves as a dock for inductively charging the battery pack. You can obviously store the base station out of sight and disconnect it from your computer when don't need it for charging, but I think you'll be fine leaving it on the desk -- Mobee's done a good job matching Apple's aesthetics, and the base station appears as if it could have been made by Apple itself. It's constructed out of aluminum and is recyclable, according to the company.
For the uninitiated, "inductive" charging works when the product is placed in the cradle (like some electric toothbrushes). You don't need to plug in anything; you simply place the rear of youror sitting in the dock for the battery to charge. Most people will charge the battery overnight and you should get about two weeks of use before you have to recharge again.
