Full Charge or trickle?

[Cpt_kludge]

Is there any way to see if the unit is being fast or slow charged? It seems that the HTC charger uses an extra pin on the charger to enable fast charging and that MAY be why some aftermarket chargers (wall and car) do not seem to keep up with the battery discharge when running even if their plugged into a charger with sufficiant current capability. The HTC Wall caheger is rated as a 1 Amp charger. I have other chargers that use an external USB cable to connect, both rated as 1.5Amp (1500mA) chargers but seem to charge very slow. Soooooo I'm looking for the difference between the HTC charger and the aftemarket ones to see if I can make the ones I have work properly.
Thanks for any help

<edit> in Looking at the Mini USB spec I find 5 pins labeled 1-2-3-x-4 with 1being VCC (5v), 2 & 3 being Data + & - and 4 being Gnd. Does the Advantage use the X pin to enable fast charging? How? Does it provide a second 5v line to cause/enable the Advantage to fastcharge? I think I need to look at the wall charger mini USB pinouts.

After talking to Pocket PC Techs and looking around online, it looks like the x-pin (next to pin 4(gnd)) is shorted to pin 4 to provide the advantage with a sense line to tell it to fast charge. The also shuts off the data lines in the unit AFAICT. Still don't know what the current capability of "Fast Charge" is or how to ask the unit to query the port for status. USB ports are generaly limited to 500ma and the stock charger is 1000ma (1A) so it seems that to ensure the MAX charge, the cable connected needs to have the x pin and pin 4 shorted. This is usefull if you are NOT wanting to do a data transfer (car GPS, stand alone charging, etc).
Here is a link to the connector http://pinouts.ru/PDA/pda_miniusb_pinout.shtml
Anyone can add to this?

I just received the Lil Sync DUO Mini-5 Adapter from PPC tech and it works perfectly. I'm now getting a fast charge from my PC (no sync) and I'm able to charge my S705 bluetooth headset.

Interesting news on the pinouts. I've never heard of any utility that shows fast vs. slow charge.

I wonder if anyone has a utility that can sense a gnd on the x pin (next to gnd) of the input connector. Does anyone have a schematic of the advantage side of the input power/data connector. It would me that there might be a pullup on that line sothe unit see's it as a high untill pulled low by a ground applied tothe x pin.
