The Archos Car Adapter and Battery Charger for AV700 enables you to keep your player charged up and ready to go, even when you don't have access to a wall outlet. It uses 6V AC input voltage and your car's lighter to power and charge your AV700. Now you never have to run out of battery for your multimedia entertainment. You can power up your player during your daily commute, on a trip to the store, or even in the middle of a long road trip. That's convenience.
