Got my tip for the N800. Works well. It pushes enough juice to charge the device while it's being used (or left idling). This is a big deal since I have found that that Solio does not reliably charge all devices and on some does not push enough juice to activate a charge cycle (creative Zen) The one thing with the Solio is that it's battery is too small to charge a number of devices from a single recharge. My iPod sucked down half the battery. it would be nice to be able to slip a battery in and out of the Solio without the use of a screwdriver. Overall a nice usefull product which is making me consider something with more charge capacity, but for the Nokia N800 this is like having another battery in reserve and you may never use the "real" charger again..well unless you have a cloudy day... ;-)
