There have been more than a few third-party responses to the Nintendo 3DS' notably short battery life, from grips to clips, to full-on battery replacements. Despite their best efforts, these products still fall short of making the fledgling handheld international flight-ready, leaving globetrotti

Sanyo's Eneloop Mobile Booster (aka, KBC-L2) battery supplies 5V 500mA of juice to a pair of simultaneously connected USB devices or 1,000mA to a single, more power-hungry tablet. The 5,000mAH Lithium-ion pack is baked right into

When we reviewed the Nintendo 3DS (both times) there were some things we liked and others we didn't, but one thing stood out as a true flaw: the battery life. Three to four hours on a charge just doesn't cut it when portable game systems are traditionally known for shrugging off entire internatio
