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.

So I visited my local Walmart and discovered a car charger, designed for Blackberry 6200 through 7500 and Motorola RAZR series phones.
The connector is the same, mini USB B.
$25,000 Question: Can I use this to charge my TMO MDA? Same connection, just worried the voltage or wiring might not be the same.
The AC chargers that came with my Razr and MDA are the same voltage-wise (5V) but not the same Amps.
MDA is 5V 1A, Razr is 5V 0.5A, they are not the same
However, it shouldn't damage the battery, just charge slower.
Just so you know, USB ports output 5V at 0.5A as well.
Edit: Sorry, I realize I completely changed my post, but didn't want incorrect info out there.
Thanks...I figured that, but was just making sure.
I got it in case of emergency...I almost always charge via USB; just leave it plugged in all day.
But you never know.....
Thanks!

Don't expect it to charge if you battery is below 30-20% charge. I'm not sure why this is an issue but it has bitten me in the rear once already.
Does anybody know why it's a problem for "less-than-1amp" chargers to charge back from the low threshold?
boxwave.com sells a 1 amp car charger. It has a USB port, so you just use it with any cable that normally plugs into a USB port. Since my Globalsat GBH-820 BT adapter came with a cable with large USB at one end, and _two_ mini USB at the other end, I can charge the GBH-820 and my 8125 at the same time.

That's not true,... if you use the VersaCharger like I do. This is where I learned of the "charging only" cable that Boxwave sells (how conveinent) and then they sell a Sync/charger for USB only. I have a Boxwave VersaCharger that I can't use without buying their "cable" to make it charge the 8125. I found this out because I have a Belkin retractable sync/charge cable that doesn't work with the VersaCharger as I had hoped. The cable that you have may work with 1amp charger but it probably won't work with theVersaCharger.
What is the output on the "min-usb" connector end of the cable? This sounds like the cable that I need for the 2 devices that I use.
...I wonder if they are putting some electronics in the cable connector...?
I bought the bundle that had a car charger (I have the regular; not the high output; not the Versa) and two mini-Sync (retractable) cables. I got caught by the fact that one of them is "charging only" when I was trying to use the "charging only" cable between my laptop and my TI-84plus calculator. I switched to the mini-USB cable that came with my calculator, and it worked fine, as did my phone with AS. That's when I looked closer at the two mini-sync cables and noticed that one was for "charging only". So, that mini-sync cable (the charging only) stays in the car, and works fine for charging my phone or my GBH-820. The really odd thing is that the "charging only" cable looks "thicker" than the one that works for syncing. Maybe lower gauge wire to help the higher current flow easier.
I have also used my other USB-miniUSB cables with my car adapter. E.g. the cable that came with the phone, the cable that came with my TI-84plus calculator.
My Bluetake headphones came with their own USB cable that has, for lack of any better term, an ultraminiUSB (or some kind of proprietary connector, cause it's not marked with a USB symbol like the other cables) plug at the end. I just plug the regular USB end of that cable into the car charger, and it charges the Bluetake's just fine.
Excellent car charger for Wizard
I have purchased and used the "Ecovell 4x USB" adapter on both a Wizard and a Universal. It provides a 2 Amp output which is equivalent to the AC adapter and works with any mini-USB cable. It will charge a Universal from absolutely dead which I have not been able to do with any other adapter. Here is the link to the item on Yes Depot:

I've ordered from them and the service was OK. I haven't seen the item available anywhere else.

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.
Does anybody know what the power output specification for car charging is for the Tilt? The wall charger puts out 5v and 1mA, but I haven't figured out what car charger is necessary. Internet sites all list different outputs including the 5v and 550mA which is the same for the Razr.
I don't want to use one that will damage the phone. Will the 550mA work but just not as fast, or can it damage the phone?
I have been trying to read other posts on this subject, but none are conclusive.
I just bought a car mount but it came with the 550mA charger and they are giving me a hard time about it.
I also notice that the usb port which charges the phone only puts out a maximum of 500mA. I just don't know much about electrical stuff and I am hoping to get some insight from you all.
All I know is that I am using Moto chargers for my phone and they're working.
I use Moto chargers and they work fine, just not as fast.
Thanks guys.
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"

Please tell me i need "PPC Techs HTC Advantage Lil Sync Extended Cable + mini 5 DUO" ( http://www.expansys.com.gr/p.aspx?i=145972) or ONLY "PPC Techs HTC Advantage Lil Sync DUO Mini-5 USB Adapter" (http://www.expansys.com.gr/p.aspx?i=145975) ?
Done a brief search on here and cannot find the answer to my question.
I have a standard car charger which I used with my my XDA Orbit (Artemis) - i'm presuming I can use this with the Touch HD? Just that I read that the connector is slightly different on the THD....
I'm also quite tempted to get one of these CC-C100 models with the HTC logo at the top (i'm not vein, honest ). Would these would work too?
May sound like a stupid question with an obvious answer, as I know they all have the generic mini-USB connector, but just wanted clarification.
Thanks
I was wondering the same.
I picked up somewhere that the normally unused B pin of the 5 pin mini USB needs to be connected to ground to enable 2Amp charging. Othewise it may max out at 500mA. So many of the chargers sold as HTC compatible will work but will not charge full rate.
The nice one with the HTC logo do have a ExtUSB connector and are rated for 2000mA so should work full charge. I am waiting for my eBay order to come in to validate.
Any miniusb car charger should work. I bought a satnav car charger and it works fine.
