Simply plug the USB side into your computer, plug the dc cable into the dc on your Archos to quickly charge your batteries while close to your PC. This cable works great with your normal USB transfer cable, as it extends the battery life of your Archos when transferring files via USB.
Now you can get everything you need for your Archos from your PC. For best results, if your computer has two usb cards, use one card for this cable and one for the USB transfer cable. This will provide a better charge while transferring files.
Cable length: 18"-20" (+/- 45cm-50cm)
