Tired of car adapters? Get an AC inverter.

If you carry very many electronic gadgets with you in the car, you know what an annoyance it is to carry around both AC adapters for when you are at home or in the hotel, and DC adapters for using electronics in the car. Whether you need to power your PDA or laptop on the go, or just charge the kids' Game Boys, a DC power inverter in your car can save you the hassle of all those DC adapters.

Several models are available on the cheap, such as the XPOWER-175 by Xantrex, which can run electronics up to 150 watts, and has automatic protection against low car battery and overload.
