That's not a desktop charger though. What we need is something that takes just a spare battery and fills it while we are using the N900 with the other battery. I've been looking left and right and found only one such product. It's not very expensive though! I have no idea if it will blow up your battery and burn down your cottage, but I might get one. If you have any other similar products, let us know!

This one's not ideal, because I'd like something where you slip in your battery so it stands vertically in a sort of docking station. This solution seems to require a lot of pushing, pulling and prying, but at least it's a start.
