1) A powered 4 port hub that accept 5-6V external power (hacked to power a usb host connection). The perfect charger for the neo.. and, well, a hub as extra function.

2) A 2.2A 5V power supply (4x500 mA = 2A + overhead).

3) A led flashlight powered by 4 D-cell (LR20) batteries that also can power the hub. (possibly also usable with 5 D-cell for rechargeable batteries (NiCd/NiMH) at 1.2V each).

4) usb keyboard and any other gadget...

5) An extra set of batteries :-)

according to wikipedia, alkaline D-cell have a capacity of ~20 000 mAh... At 6V given 4 D-cell.... but I guess no more will come out of the hub at 5V.

That's 16.7 times 1200 mAh... but how efficient is the charging of the phone... can one expect 1 or 5 or 10 full charges?

And how much dose the phone consume over usb when already charged?

Would be nice to be able to get a rough estimate on have long lifetime one can expect.
