This is a power supply system with multiple AC power plugs, plus a rechargeable unit, plus a USB charger cable, AND a folding solar panel. You will always have power for your gadgets. The system icludes multiple tips including the Nokia mini for n800. This is a serious product (not a toy) and has good reviews. Check out: http://www.powermonkey-explorer.com/ for additional details and spec sheet. It's worth noting that this system includes various forms of circuit protection, which most chargers and adapters don't have.

Normally this system sells for about $100, but right now Buy.com is selling it for $10 after a $100 rebate. The final cost of $10 includes free shipping. Yea, a $100 rebate is a risk and a hassle, but I have never had a problem with Buy.com in the past. I've bought various electronic items there including my n800. Just be sure you follow the rebate directions (and make your purchase with a credit card). I am not affiliated with PowerMonkey or Buy.com, just want to share this value with fellow IT-ers before the stock runs dry.
