OMG! I just did something really dumb with my X51v!

[Nerve]

I just got my replacement Axim X51v (my previous one had a bad firmware flash). I thought I plugged in the Axim AC adapter to my Axim cradle, but today I realized I was actually plugging in my PSP power adapter instead! And I had let it charge over-night. I looked at the power specs and the PSP power adapter outputs 2000 mA, while the Axim power adapter outputs 2410 mA so I actually underpowered my Axim. I'm worried if I fryed something. My Axim seems to be working normally (except the still-glitched SD-card problem everyones still having), but I want to know if I made some physical damages to the hardware or anything?

no i think some people here use psp adapters.

Going lower on the mA should not have done any damage. The worst case scenario on this one would be a bad battery charge but leaving it ovenight may have fully charge it. It is going to be OK.

Under powering generally isn't a bad thing......over powering however tends to lead to bad things.

Relax, it's most likely just fine.

Current isn't critical until you get below that required by the X51. Typically, with a relatively full battery, 1A, or 1000 mA, should do nicely. 2000ma also should be plenty, unless you are running full speed, high brightness, wifi and bt on, almost dead extended battery, at which time you could get to 1900 ma demand.

The Axim will only draw the power it needs, up to the full rating of the power brick, so you're fine with the PWP supply at 2000 ma.

Thanks for the extra info Jake :approve:

Well one thing I did while using the PSP plug was update my Firmware to A06. I did it when the battery was near medium. It seemed to have worked nicely - didn't notice any hiccups whatsoever.... This power adapter problem probably didn't affect the Firmware update process any did it?

Nerve, no roblem at all. As Jakerich said, your Axim draws the amount of current needed to charge. Current rating, as long as it is sufficient for the application is irrelevant. In this case, your 2A charger was fine, and it wouldn't have made a difference if it was a 2.5 or even 5A charger. The voltage rating is what is more important, and in this case they are close enough to be fine.

If there could have been any damage done in this case, it would have been to the power adapter. If your Axim were to start pulling more power than the power adapter could supply, the Ax would have switched to battery. At half charge, with no radios running, no way this would have happened, barring faulty equipment. Also, half charge is way more than enough to finish a flash, anyway.
Generally, they will pack an AC adapter capable of operating under worst-case situations, plus 10% or more. I have extensively used a 2000mA AC adapter with a 5.0VDC regulator with zero problems (View MyPDA).

Great info guys... I guess that means I can use my old charger for my Toshiba E550G... 3000 ma, 5v

[darkdestroyer]

I've used my psp charger for a while now with no reprecussions yet.
