As the N800 (unlike my Palm T3) supports a proper, normal charge plug instead of those ridiculous, unreliable error-prone multi-connectors, I would just go for a USB-to-chargeplug cable instead, charge from USB that way and leave the N800 USB connector alone. One of the _good_ things, nay, one of the _best_ things Nokia ever did was to stop using a proprietary junk multiconnector in their devices (unlike most other makers). Which also means, IMO, that the need for USB charging isn't that big really. Anyway, that's how I think about it.
