PSP power supply sounds like a decent option, seen them locally for around $15-$20. I also see on eBay an extra "travel adapter" for the Axim can be had pretty cheap.
After this last weekend, 1300 miles in two days and several stops to "readjust" the power cord, I don't think I will try another Pocket Solutions charger, here was my experience:
- Will always charge standard battery when Axim is turned off, irregardless of tilt/pressure on connector
- Will always DISCHARGE the mega capacity (3600mAh) battery, even when turned off
- Will not power unit and charge simultaneously with standard battery until 90% charge, and even then it requires a fair amount of tension/pressure pulling back on the connector to power the unit but not to charge the battery
I had to fasten back the cable pretty cable pretty good to keep enough tension on the plug to maintain the connection to power the unit (not charge, kind of odd) with road vibration, and now the unit has to be "nudged" and wiggled to make the connection in the factory cradle but still works fine with the OEM travel adapter...
I could go on and on about a few other issues I had, but it pretty much doesn't matter anymore, I was so frustrated when I got back home that when I saw someone selling an vehicle GPS on Craigslist pretty cheap today, I picked it up and think I got a great deal. Not as nice as the iGuidance software I have in my Axim, but definately does the job for my needs.
Not to say anything bad about the Axim, for its main use for me (a real-time paperless geocaching GPS) it works great.
Now if I could just waterproof it with my CF GPS card installed, life would be perfect!!! Guess the gallon zipper baggies will have to do for now...
