Apparently a normal power inverter just can make little impression. Want a special one? Let’s go on checking the coffee cup shaped power inverter.
The fun power inverter is shaped just as a coffee cup. In fact, it’s actually able to offer juice, but for your portable devices instead of you. The power inverter comes with two AC plugs and a USB port. Through the cigar lighter outlet in the car, it can turn your car’s DC power into 120-volt AC power for powering or charging your cell phone, MP3 player, and other portable electronics.
The coffee cup power inverter can support the universal cup holders in auto, boat and truck. It costs $29.99 USD. If you’re interested, jump to ThinkGeek for more details.
