Our smartphone batteries these days don't last more than 12 hours without needing another charge. So it's no surprise you probably have somewhat of a backup battery at hand. But what if you needed it for other products?

Lenmar's new ChugPlug is designed to integrate with the MagSafe adapter to give you a few extra hours of precious power. The ChugPlug will cost $160, and is compatible with both 45W and 60W MacBooks and will give your laptop four extra hours of battery life. Look here for more information: [Lenmar via Acquire]
