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.

(Gamespot) – The third time’s the charm for Nintendo. The company has announced that its newly released DSi handheld–the follow-up to the original DS and the DS Lite–has nearly doubled its predecessor’s debut sales. Citing internal tracking numbers, Nintendo said the DSi sold 435,000 units in the US in its first week of release, compared to the DS Lite’s first-week tally of just 226,300 systems sold.

The news is not terribly surprising, given that Nintendo president Satoru Iwata already announced that the company had sold 300,000 DSi systems in the US during its first two days on sale. When the DS Lite debuted in 2006, Nintendo said it sold 136,500 units in the system’s first two days on sale in the US, putting it roughly on pace to match the launch of the original DS in 2004.

While those early DS Lite sales figures may be promising, they weren’t enough to address investor concerns over Nintendo’s performance in the industry tracking NPD Group’s March US retail sales figures. While the Wii and DS continued to be the top-selling systems, both saw sales slipping significantly month over month and year over year. Nintendo shares closed down 6.6 percent to ¥26,180 ($263.47) on the Osaka Stock Exchange today, with shares trading hands at nearly three times the normal rate.

Nintendo of America president Reggie Fils-Aime told Bloomberg the slip in March sales was due in part to the absence of a blockbuster hit like the prior year’s Super Smash Bros. Brawl, which sold 2.7 million copies in the US in its debut month. While not nearly as huge, Nintendo did score a major US hit last month with Pokemon Platinum, which was the second-best-selling title of the month with 805,000 copies sold.

“Our launch schedules are more spread out so we’re going to have these tough comparisons month-to-month,” Fils-Aime told the news service. “But if you look at the overall trend of our business, it continues to be very healthy.”

(Gamespot.com) – In December, Nintendo tipped its hand on its early-2009 lineup for the Wii and DS, revealing March launches for New Play Control Pikmin and Pokemon Platinum. Today, the publisher augmented that list with more specific windows for a handful of games, as well as for its highly anticipated handheld redesign.

Of note, Nintendo’s revamp of the classic NES boxer Punch-Out is now expected to arrive for the Wii during the first half of 2009. Though Sega and Platinum games had already confirmed Madworld for a March release, Nintendo today nailed down the stylized action game for a March 10 release. Nintendo also narrowed the release window for High Voltage Software’s anticipated Wii-exclusive shooter The Conduit, saying the game would arrive by June.

Lastly, the publisher also provided a small update on its latest hardware revision for the ultrapopular DS, which has sold 96.2 million units through the end of 2008. Nintendo now expects to launch the DSi in North America sometime this spring or summer. Unveiled in October and already available in Japan, the DSi is thinner than its predecessor and features 17 percent larger screens. The redesigned handheld also boasts two cameras.
