Half off-topic.

Look at this combo 3-in-1 USB AC and Car Charger. It looks to me like it could substitute for this cable to be used with an external battery pack (like Cptnodegard does in the above post). Think so? (More specifically, Cptnodegard, do you think so?)

And if I'm not mistaken -- please tell me if I am mistaken! -- it could also work as an AC charger instead of getting a second Nokia AC adapter; and it could work as a car charger. (This all assumes that one of those adapters fits the Tablets power input socket, which I think is likely.) Do you think it would hurt the Tablet to charge with one of these? Any other downside?

In theory, yes it will work. The 2mm nokia jack is standard for nokia phones hence why its in such packages. However the Ca-100 cable contains some circuitry to regulate the voltage up to 6.5V (USB is 5) so ther emight be an issue with using another cable. I myself is waiting for a cable with a strap form china, not a ca-100 cable, if it works it should mean that one will work too

edit: some charger pron fo rthe people:

Thanks for getting back to me on this. I'll postpone buying the combo or the ca-100 cable. Once you get the new cable, please post about how it works out, and then I'll choose which way to go. Thanks again.

I have two Tekkeon MP1550's and I'm experiencing problems I've not seen posted here. I was wondering if any of you that are using the MP1550 might be able to assist. I am only getting about 15-20 minutes of power before the three LED's go dark. If I pull the batteries from the MP1550 and test them they all show indication of having a full charge.

This occurs with any of 5 sets of 4xAA batteries, fully charged, ranging from 2000mAh to 2500mAh. I have three different USB Nokia charging cables - all test good for continuity and no shorts. All five 4xAA battery sets are brand new - two sets are Energizer E2 2500mAh NiMH, three sets are Duracel 2000mAh NiMH. All of these sets have been charged 2-3 times now but I don't believe they have ever been fully discharged. The MP1550 (both of them) indicate no power long before they should.

I did continue to use the N800 long after the LED's went dark on the MP1550 once. The N800 seemed to indicat that it was still charging but battery life was about what one would expect from the internal battery alone from that point forward (i.e. no additional battery life from the MP1550 once the LED's went dark).

I currently have one of the Duracel sets that the MP1550's report as discharged in a flashlight and it has been lit strong for hours, shows no signs of dimming.

The batteries themselves could be the root cause but I rather doubt that 5 new sets would all be defective. I would have thought the MP1550 to be the problem but I have two of them, both new, and they both behave this way.

Any input / suggestions would be appreciated. Thanks!

Just a guess but since nimh are about 1.2v they may quickly drop below the required threshold at which the charger is prepared to work. How about trying a set of alkalines and doing similar tests?

Thanks for the quick reply! I'll look around for a set of alkalines to test with. A few others here have reported excellent battery life using a MP1550 and NiMH AA batteries though and I'm curious as to what is different. For those of you using NiMH batteries in a MP1550 - have you experienced any similar issues? Thanks again!

Indeed. After a few months of use, my knock off CA-100 USB power adapter from DealExtreme melted while charging my N800 from a low power USB port on a notebook computer:

As far as I can tell, my N800 is fine. I don't think the meltdown damaged the notebook computer either, but I haven't actually tested the USB port yet.

I'm simply happy that my wife and I were in the room when the adapter apparently shorted out. The strong smell of melting plastic came on suddenly, and the adapter was hot when I pulled it from the notebook computer. I've often left this adapter unattended, connected to an A/C-to-USB wall wart to charge my N800 in the past, and I can't help but think the adapter may have started a fire if we hadn't been there this time.

I have not had it very long so can not give you feedback on how much juice it will give out before it dies but I will keep you updated.
