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.

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.
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.

My Defy is extremely picky when it comes to charging.
I tried a few different power adapters. All run at the standard 5V used by all USB ports. The only variable is the current.
The power adapter shipped with my Defy spits out 850 mA and apparently my phone doesn't like to eat any other current. With a 500 mA adapter my Defy won't charge at all. That's strange, because it charges fine when connected to my computer, and those USB ports max at 500. At 1000 mA my Defy charges OK, but the screen becomes hypersensitive. Just moving my fingers within 10 cm from the screen is enough to scroll, make icons believe they're tapped, and make the phone do all kinds of random stuff. Spooky!
My other phones all charge fine at 500 mA, 800 mA (default Nokia charger current), 850 mA, and 1000 mA. They don't seem to care about the current at all. Same for my camera with a microUSB port. Any current from 500 to 1000 mA works. Only my Motorola Defy is playing difficult and insists on 850, not more and not less.
Does this mean that there's something wrong with my Defy or is this deliberate sabotage by Motorola to stop us from using competing power adapters?
Mine charges off the Motorola one, a Sony Ericsson one, a ZTE one, a cheapo Tesco one and off the PC USB ports. The output of the charger will only effect the charge time.
Right now charging mine off my Kindle a/c charger. Seems to work.
Of course the Kindle adapter works. Its output current is 850 mA, just like Motorola's own adapter.
Did anyone ever try to charge a Defy with a 500 mA or 1000 mA adapter?
It wont work with chagers which are being made for other phones
http://forum.xda-developers.com/showpost.php?p=13871623&postcount=49
800mA current
Even an 800 mA charger won't work? That sucks. Why did the phone manufacturers agree on microUSB as charger port standard?
Fortunately my cheapo 1000 mA adapter works, as long as I keep the display switched off during charging.
Hey my Old Samsung phone's charger 0.55A(4.75V) works best! charges faster than moto's charger! Bdw switching chargers isn't good for Batt life i read this sumwhere....
use moto charger!
It's the max output the charger can sustain. Just like the specification on electrical socket, fuse, cable etc. So it doesn't matter as long as it is not exceeded.
It works with SonyEricsson charger but not the one for HTCLegend
I have not experienced any problems with charging from a variety of adaptors. However I do have a couple of the portable li-on battery backs, they seem to have enough juice to recharge/power PSP and DSLite, but can't supply enough current to charge Defy or my San Francisco.
Does anyone know of any reasonably priced portable power packs that can do the job?
On my defy I've used my gf's HTC Desire charger (1A), and it was all good, no hypersensitivity. But I remember I bought a cheap no-name charger for my itouch and when I was charging it, there were similar issues you said.
i'm using my nokia E66 data cable in lieu of my motorola cable to charge my phone. no issues

I have a similar problem as you.
I think the Defy only charges with 500 mA to maybe 1000 mA. I can charge my Defy with any PC and Tablet USB ports, a Nokia AC charger and a couple of car USBs with 1A output. However, it won't charge with 2 other car USBs with 2A output. I measured the voltage of these two and they are good, at around 5.2 to 5.3V.
I was hoping to find a higher capacity car charger because I am using my Defy as car camcorder, and 1A simply cannot supply the current needed!
My defy can be charged with an htc 1A charger as well as a 500mA samsung charger. But it refuse to charge from no name cheapos.

Tried a new adapter, made by Sony Ericsson. 5.0V, 850mA, exactly the same output as Motorola's own power adapter. But the SE adapter has the same problem as the no name adapters I tried: they charge my phone, but I need to keep the screen locked 'cos the adapter makes it hypersensitive.
So it must be my phone. For some strange reason it doesn't like it when I use any other adapter than the one that came with the phone.
I wonder if its refusal to work with non-Motorola adapters is a reason to get my Defy fixed under warranty...
The problem you guys are facing is not related to the current, but to the pins used by the cable in the USB interface.
The defy will only charge if it is connected with a full USB connection.
Not all the USB cables come with all the pins, I for example have one for my Bluetooth headphones that only has power and it does not charge my defy but it does charge my hd2.
Gesendet von meinem CM7 Defy
The problem persists when I use the Motorola cable with a non-Motorola adapter.
When I use the Motorola charger adapter together with non-Motorola USB cables my phone charges OK.
So the problem has nothing to do with cables and pins.

It has to do with cables and pins.
If your cable has all the pins (normal data USB cable) but your adapter doesnt have them connected is the same thing as having a USB cable with only power pins.
Check out cables diagrams to see how them work.
There is even a hack for some HTC phones, where you actually short some pins on the cable so the phone think it is connected to a wall charger and not a USB port, allowing the phone to use more than the 500 mah the USB can provide (useful for car adapters).
This is fact, I'm not pulling it out of anywhere hehe
I charge both my Defy and the HD2 with the same HTC charger, and I have a extra USB portable battery, which charges the HTC but it doesnt charge the Defy, both are running CM7.... the issue? the danged chinese battery only has power pins and the phone refuses to charge from it @[email protected] it does charge my Bluetooth Headphones and the Camera
My non-Moto 1000 mA and 850 mA adapters make my screen go wild, but they charge my Motorola Defy.
If it was a cable/pin issue they wouldn't charge my phone at all.
If I plug my knockoff 500 mA adapter in my Nokia USB port (which is for data only, not for charging) my old Nokia pops up a "USB data connection detected" message.
Not all charger issues are due to cables and pins. Sometimes its the output voltage and current that messes things up.

I know not all issues are related to the cable and pins, but this specific issue with the Defy not charging is.
Both your chargers comply correctly with USB charging standards then.
Notice this also happens on the Droid, and shorting both Data pins allows the phone to charge. And can be read on the forums that it works too with the iPad
Anyways, here is what happens to the defy:
http://en.wikipedia.org/wiki/Universal_Serial_Bus
"There are also devices at the host end that do not support negotiation, such as battery packs that can power USB-powered devices; some provide power [...]. USB power adapters convert utility power [...] to run attached devices. Some of these devices can supply up to 1 A of current. Without negotiation, the powered USB device is unable to inquire if it is allowed to draw 100 mA, 500 mA, or 1 A."
There you go, no Data pins = Defy do not draw power, not charging.
I would like know if it charges shorting Data pins tho.
All that is required is short both Data pins with each other, doesnt matter if its on the cable or the charger.
