Both Palm and Powermat wireless chargers pump out 5V and 1amp, but the main advantage of the Powermat is it allows a little bit of a gap/space between the wireless charger and the wireless receiver... or in other words, you can use a normal thickness case with your phone while charging.....
I used the following:
1. Powermat receiver for Blackberry Pearl 8110/8120/8130
2. Powermat Wireless charging dock
3. Flexible PCB - copper clad laminate (pyralux)
4. Soldering iron
5. Kapton tape
Items 3 and 5 are optional... I'm sure you can use copper wire or copper foil tape, and electrical tape. I already have those items so I just utilized them.
My UNscientific measurement for charging rate 14% per hour
Technique is again a bit or origami and a bit of soldering.....
2 - The POSITIVE terminal is the one on the LEFT side
3 the circular magnet was broken into pieces here (now replaced with a new unbroken magnet) but charging still worked
