Wanna look like a nerd from the 80's but have a 3DS?

From ThinkGeek.com, this wristband contains a 1500 mAh lithium ion battery. Using four LED lights, the LEDs show you how much battery is left. Weighing an 82 grams, the wristband is very portable and cool looking for your nerdy friends.

If I were ever to pick up a 3DS, I would definitely buy this. In order to ‘increase your portable gameplay time’ for $35, I think this wristband would be worth it if it gains at least two hours.

Available for the iPhone, Nokia II (2mm) and I (3.5mm) phones, Mini USB, LG phones, Samsung i900, Sony Ericsson phones, Sony PSP, DS Lite & DSi: you have plenty of portable phones and gaming devices to use this with. Check ThinkGeek for the Universal Gadget Wrist Charger.

One of the best parts of road trips is quality time playing our favorite handheld games. (This is, of course, why you insist someone else drives the vehicle.) But the problem with long road trips is that you often exhaust the battery life of your gaming system before the point on the road trip where you really, really need it. Of course, we’re talking about mile 150 of 300, where the guy riding shotgun starts in on a political diatribe and the person sitting next to you begins to have intestinal upset from the food recently delivered through the driver’s side window. Where’s Mario now? Oh yeah, he’s dead until you can find an outlet. Are we there yet?

The Wrist Charger, or as we like to call it, Bracer of Battery Life +2, straps comfortably to your wrist and plugs in to just about any electronic device you like. It’ll power cell phones, mp3 players, gaming systems, or any device compatible with mini USB. Now you’ll have plenty of power to get through long days traveling (or long lines at the DMV, we’ve been there, too!). When you reach your destination, simply plug your bracer in and charge its battery back up so you’re ready with plenty of entertainment for the long trip home.
