External Battery Pack for about $5: I've made an external battery pack for not much more than $5.00 total, excluding the batteries. I had a battery case from an RC car. It can hold 4 AA batteries for 6 V output. I ordered an AC charger/adapter from Amazon.com (http://www.amazon.com/Travel-Adapter...324041&sr=8-14) for under $5.00 includling shipping. What I did was to cut the cord off the charger and then attached the remaining cord to the battery pack. I had some AA NiMH batteries laying around, so I inserted 4 of these puppies in the battery pack and then connected it to the N800's power jack. Voila! The battery starts charging. I'm going to do some testing and experiement. The NiMH batteries are rated 1600 mAh each. I don't have a multimeter where I'm right now so I can't really measure the output voltage but I'm sure it's somewhere around 5.2 volts when fully charged. After about 20 minutes of charging, my N800 went from 56% charged to 74 %. Yes, it looks ghetto, but for $5 spent on it and the fact that it works and works rather, I am pleased. I took some pictures. I'll post them later, Ciao,
