I have two backup solar batteries from Daylight Savings ($25 inc shipping) that pretty much work really well for me. One I keep in the car, and the other in my bag. Both can charge via solar and USB, and will render just enough of a charge to keeping me solid until I hit a wall wart.

hehe, sorry my bad
nah, i don't think it'll destroy the device, provided it provides a constant output through the microusb...

The proporta was left with 4 LEDs on.

Then I fully charged my n900 from the first low battery indication and this took 2 hours.
how come some people say that proporta external battery pack works for them with the n900 and some say it doesn't?

since battery is problem, i got travel charger from Fry's store at $ 3.99( Biztech or mytech) and officedepot has CASELOGIC Ac-Dc wall adapter for car chargers for $ 9.99 and it works fine. i have tried it. i tried lot of ac-dc adapters and most out there are compitable with iphone and those does not work with N900. best thing is buy it try it in parking lot and if not worked return it.

I purchased a Energizer XP2000 and a Scosche sunVOLT solar battery/charger (this was on clearance).

The energizer only works if I plug the microusb into the n900 within 1-2 seconds of hitting the status/on button.

Plugging the n900's usb cable into the sunVOLT's female usb adapter produced no results, but using the cable and microusb tip from the XP2000 got this working as well.

As far as I can tell, power must be live on whatever you want to charge on before/during the initial insertion of the microusb plug into the n900. Hitting the juice after insertion does not appear to make the device charge.

I don't have a ZAGGsparq, but was considering one before hearing that it didn't work properly with the n900.

Has anyone managed to get the zagg working by shorting the usb cables as has worked with some other chargers? I have a feeling a similar circuitry in the XP2000 cable/tip is what enables my n900 to charge from the sunVOLT

Hey, thanks a lot for that tip !

I have a Sanyo Eneloop USB booster that worked just fine with my tablets and phones, and I was very disappointed that I could not seem to use it with the N900 through the microUSB cable...

The only way I could make it charge was by chaining a Nokia USB-to-small-round-tip adapter (CA-44), the round-tip-to-USB adapter block that came with the N900, and the microUSB cable... unpractical, to say the least ! :-)

Even then, the Eneloop booster emitted a loud-pitched whine that it didn't usually have, as if something was wrong with the electronics, which made me uncomfortable.

I just hadn't thought of pressing the booster's charge button *before* plugging in the USB... now it works just fine, including with a 1$ third-party "ziplinq-like" adapter, with no whine, so all is well again !
