when you need a hand crank charger you know you have been surfing too much on the 770 and your eyes probably need a break, lol

Well I won't be buying 5000 of those anytime soon

They look to me to be next generation giveaways now that self-retracting modem cables are so passe

Russ -

Not that I doubt you at all, but I'd be really interested to see anything you can cite about this. I've been doing "deep cycles" with my 770 as I /thought/ this was the best way to run it but, as I say, I'd be really interested to see something conclusive saying the opposite!

Many thanks!

Check this article out http://www.batteryuniversity.com/parttwo-34.htm

Based on this, I try to do two or three full discharges with a Lithium Ion or Polymer batter and then after that, keep it topped up. LIon batteries don't suffer the memory effect of older NiMh batteries, and even those have improved to the extent that the memory effect is much reduced.

Apple suggest a complete discharge once a month for battery conditioning, though I tend not to follow that suggestion.

I bought a Nokia car charger, at CompUSA for $12 US. But you can get them (the DC-4) on eBay for about $8 or $9 US. I keep the charger in my car always, and then I have it at work, since I drive to work, and I leave the regular charger at home. If the 770 was to ever run out of power during the day (unlikely), I could always take it out and stick it in the car to charge.

I get exceptional life out of the batteries - 4 or 5 if I am streaming radio, and basically all day if I am simply surfing the web. As a regular tablet, without using the internet, it will last longer. I am really pleased with the battery life.

If you have a short battery life, just turn the brightness down a little, and maybe decrease the sleep time setting.

How long does it take to complete a "full charge"?

How well does that one work?

Then maybe one could combine it with this cheap product: http://store.sundancesolar.com/flsobachfor4.html ?

Here is the link to compusa.

Or maybe a little more. I tried playing some mp3s non-stop, and the 770 kept on going for around 16 hours.

Streaming music over the network would be a different matter.
