A review and demonstration of the iWap IUC-11 Universal Battery Charger. It can charge and revive 99.9% of 3.6V and 7.2V lithium-ion batteries, as well as AA/AAA NiMH and NiCad batteries! It automatically detects the polarity of charging terminals (so you never have to worry about putting a battery in backwards or upside down) and can charge USB devices as well. It can even use a charged battery to charge a separate device via USB port! This model also features a built in LED and a Turbo mode for quick charging. Can be used with laptop AC adapters, as well as for charging cell phones
