Have 3 devices.... which when used with two different car charger cables and several vehicles give the following consistent results:-
1. O2 Atom - Doesn't recognise any external power
2. HP rw6828 - Recognises external power, shows battery charging but the battery discharges rapidly
3. Dopod 818 Pro - Recognises external power, shows battery charging and does charge
Any ideas would be appreciated as both O2 and HP seem unable to help.
did you try both:
1. adapter
2. USB charging?
Hi,
Same problem for me on atom. I think the atom is a power hungry device, you'll need much more power from the car charger. I bought an excellent item from boxwave, called versacharger pro. (http://www.boxwave.com/products/versachargerpro/index.htm)
With a simple usb cable, it charges in my car really fast, and works perfectly too as a wall charger. It isn't cheap, but worth the money.
Hope it helps!

Hi folks,
Love my MDA II, but I can only get it to accept a charge when my laptop is turned on. If the unit is not plugged into USB or the laptop is not on, it won't charge.
What am I doing wrong?
Finally, I have noticed the last few days that the wall AC adaptor has not been plugged in, yet the MDA has been charging through the USB when the laptop is on.
My question is what is the point of having the AC adaptor if it serves no purpose.
I rechecked and pulled the USB and plugged in AC adaptor. No charging takes place.
you are doing nothing wrong. the power thru the usb port comes only when the laptop is powered up (whether the AC power is on or not ).
In other words u can
1. charge it from your laptop's battery but the laptop has to be turned on and it does not matter if the AC power of the laptop is plugged or not
2. you can charge the XDA directly thru its own AC adapter, independent of the laptop
The AC adapter does have a use, you can either use it in conjunction with the little square dc converter that you get free in the box to charge up the xda without the cradle, so you could have the cradle at home and tyhe AC adapter at home if you wished, and if you plug the AC adapter into the cradle you can charge an aditional battery, as the additional battery can not be charge via USB, Maybe xda developers may be able to frig the cradle to charge the additional battery in the future (hint hint)
Cannot charge xda executive with car charger ,when connected nothing happens light does not go red and also the connection icon does not show
make sure you dont have a faulty charger... dont know what you are using but i believe most people use the cigarette lighter to usb converter and then just use the usb cable... also have you tried pressing the on and off swith with the charger plugged in ?

Hi and thanks for the fast reply mate <yes it is a new charger from o2 .
No i have not tried the on off with the switch ,but would i still be able to charge when i am using tomtom
Whell....I use the cigarette lighter to usb adapter and usb cable ...at times i have had to quik press the on/off swith and at times plug and unplug the cable to get it to charge ....I used this as a "jump start" method only and no problems after that with using it whillst on charge (even with tomtom)..... other than that you may have a faulty charger or fag lighter to usb adapter (I never seen what a o2 one looks like).

Is the charger one especially for the exec?
I found normal usb chargers for phones like V3 or a GPS charger cant supply enough current to charge an exec.
hi, yeah i have had this problem, and so have a few of my clients, seems that not enough juice flows through the non branded versions, unlike from o2's or Brodits cables
I found that a regular USB cable into a Cigarette Lighter -> USB Socket didn't work until I joined pin 4 to pin 5 on the USB B Mini plug. All of the adapters I had that worked, but only powered (no data, i.e. Brodit and mains adapter) seemed to have pin 4 joined to pin 5 (pin 4 isn't normally connected at all). Once I did that mod it worked fine.
Cheers,
Steve.

Orange shops carry a charger intended for HTC manufactured devices (i.e. the SPV C500/M500 range) which works fine. Only £9.99.
Hi
The charger that came with my HTC P3600 says 5V, 1A. However most of my other miniUSB chargers which I use with a I-mate JAMin & K-JAM say 580mA or 500mA. I also have some adapters for the HTC P3600 which would allow me to plug in one of these miniUSB chargers. The question is should I? Would it make any difference? In case you're wondering why I would want to do this, its because I have a charger at work, home, girlfriends, in the car etc. And I would rather have a few adapters than shell out for loads more chargers. Thanks for listening!
Well, the Amp on your charger is how much Juice it can deliver.
So as far as I can guess you would have 2 scenarios, 1 is it will work but it will charge your HTC slower, or second option is that the charger will overheat.
I bought a usb to car adapter recently for my ameo, and still, power is being drained from my pocket pc when i run tomtom.
Is it the charger?
its been brought up before somewhere, the athena's wall charger is 1amp, car chargers and usb are lower, usb only being 500ma, so it takes longer to charge but using the car charger the battery should last a lot longer.
you need one of the pocket pc techs mini 5 adapters
without one, using an amp meter, my athena pulled 350-400 ma off of any charger i hooked it to (using usb cable).. wall charger, car charger, computer usb didnt matter.
using the ppc techs adapter... upped the draw to 750-775 ma, it charges 2x as fast, and more importantly, doesnt run down the internal battery in the car, while running tomtom.
I got that trouble with my old charger coming from Mitac Mio A701 since gives me 500 mA. I got the HTC car charger at Expansys (original HTC charger for car) and gives me 1 A... and now I got no trouble. I can use Tomtom all the way home full screen bright and HDSPA with Blackberry Connect working and the X7500 still charges.
So got a 1 Amp car charger. I got the HTC one because someone told me the pinout is different and use the 5th pin to run quick charge. I cannot confirm that... sorry, but I got the HTC and works.
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.
here you have "hot to do it"
