This is one powerful cup of coffee! Actually, it's a clever design for a power inverter. The shape fits conveniently into your car's cup holder. A must-have for the commuter or road tripper, our inverter can power three devices at once. This triple espresso has 2AC outlets for laptops, DVD players, phone chargers, camera chargers, etc. and one USB power port for iPods, MP3 players and cell.
