And heres why,
Computers only have an output of 500mAh. The Touchstone is looking for 1000mAh. The 4 port hub you bought more then likely follows the computer standard of 500mAh. My work got me a Pre for a few weeks before I went back to my Touch Pro (which by the way needs 1000mAh to charge properly as well.) Cool thing about that, it has a cord with 2 usb dongles on the end and 1 mini usb for the phone. On my Touch Pro I have a program that shows me current output (battery drain by the phone), charging current input, voltage of the battery, and percentage of the battery left. It's a great tool for testing chargers, both wall and car, and USB ports to see what the current out put is on the devices. Several times when I have had it hooked to my computer for Syncing, it will show 500-600mAh drain, while only charging at 475mAh. Apparently when its hooked to a computer, its processor is working pretty hard. This draws the necessary 500mAh X 2 = 1000mAh with out damaging the ports. Ok with that said, there are some after market car chargers that put out 800-1000mAh of current at 5 V DC for the devices. I have one in my truck and it worked just fine for the short time I had the Pre. I also have a Motorola 1000mAh wall charger in my office that worked just fine with the Pre, same with the stock Palm charger that came with my 800w. Its not really looking for a specific brand, just the right current output and voltage. Hope this helps. _____________________________________ Sprint HTC Touch Pro Blackberry 8320 PIN 247FA6E9 PDA Repair - Blackberry, Treo, Windows Mobile Motorola 2-Way Radio Service and Technical Consulting http://www.capstonewirelessllc.com/Handsetrepair.htm http://www.twowayshopper.com http://groups.yahoo.com/group/GMRSDallas http://tech.groups.yahoo.com/group/TreoPro _____ From: [email protected] [mailto:[email protected]] On Behalf Of Don Pomplun Sent: Friday, September 04, 2009 3:25 PM To: [email protected] Subject: [Treo] [Pre] charging anomaly I just picked up a plug-in Lenmar charging pack with 4 USB ports to take on a trip. Checking it out before the trip, I find some strange things that seem related to Palm cords -- I have the one that came with the Pre and a similar(shorter) one from the Palm car charger. Either cord used with a Touchstone, plugged into my PC's USB port won't charge., but plugged directly into the side USB port on the Pre works as expected. Either cord used with the Palm Wall wart works OK on Touchstone or side port. But plugged into the (2 amp) Lenmar only works on the side port, not the TS. Strangely the Palm cords work with the TS using my Kindle charger. wazzup? Don (CA) [Non-text portions of this message have been removed] [Non-text portions of this message have been removed]
