I'm not sure of the cause, but the Treo Pro requires a high quality (e.g. OEM) wall charger. My GUESS is that the battery voltage on the TP is slightly higher than normal, so the charging circuits in the cheap wall chargers start to scale back too early. I have found some of my wall chargers work just fine with the TP and others do not, even though the specs are identical (same nominal voltage and amperage). Bottom line: a) go to eBay and buy a Palm (or other OEM) charger or b) install PowerGuard (freeware available on net to measure power consumption/gain) and then go to a phone kiosk in the mall and find a charger that puts at least 300 mA net into your phone. Good luck.
