GREAT steal... I have this myself, and wow it does a great job in keeping your n800 charged on the go. After being 100% charged, it can hold up to 2 N800 battery charges I believe... Definitely worth the money!

On another note, you use the same n800 charger to charge the device ~

hope this helps ppl out
