Sanwa 400-BT001

The new iPhone 3G might be phat and all, but surely the combination of a large touch screen display, 3G connectivity and relatively small size makes a potent combination for poor battery life. Sanwa forsees that problem and has a solution in the form of the 400-BT001. This rechargeable external battery will provide the iPhone 3G with extra 3.5 hours of talktime, 7 hours of video playback and more than 5 times that amount when it comes to non-stop audio. Each of the 1,200mAh Lithium Ion battery is equipped with a retractable USB cable and a LED that indicates the remaining battery life. The Sanwa 400-BT001 will add another 50 grams to your iPhone 3G, but the benefits far outweigh the sacrifice. At $46 a pop, this is relatively cheap.
