Several people have asked my questions regarding the connector on that adapter that comes with the XDA II and allows you to use the AC/DC charger without the cradle. :idea:
THis info is quite usefull, also if you are building your own usb sync/charge cable.
First off, the AC/DC charger is rated at 5V and 1 amp, though it has a no-lead voltage around 6.3V (GND is on the outside of the charger plug, +5 Volts on the inside hole/pin). You don't really need the 1 amp to charge the XDA, it's just there so that you can also charge the second battery, which you can insert into the cradle .
Now for the Pinout on the adapter. See here for more info on the XDA connector: http://www.xda-developers.com/connectors/
Pin 20,21,22: +5 Volt
Pin 16,17,18: GND
Pin 5: GND
Shorting the lines across three pins provides current load leveling for charging.
Now for the usb sync/charge cable. Here we need to add the following pins:
Pin 2: GND (my usb charge/sync cable does not connect to pin 5, just pin 2, so these are probably shorted inside the XDA)
Pin 13: +5 Volt
Pin 14: USB Data H(+)
Pin 15: USB Data L (-)
From the design, it becomes evident that the pins 16-18/20-22 are only used for the charge circuitry. There is probably a current sensing circuit in this set.
Pins 2 and 5 are the digital ground. Pin 13 powers the usb circuitry, also waking the XDA and starting AxctiveSync.
BTW: The PDA will only charge if at least one of the pins 16,17,or 18 isconnected to ground and at least one of the pins 20,21 or 22 are connected to +5V. Otherwise, though the XDA may say it is charging, it will actually just drain the battery.

I just received my iMate XDA2. I have a charging connector/USB cable combo left over from my XDA1. I inserted it into the XDA2 and the amber glowed (charging) and got to green (charged). Your comment about if pins aren't grounded, unit appears to be charging but actually isn't. Is there a way to confirm the charge/USB combo is actually okay for my XDA2?
from what ive heard/been reading the XDA 2 charger kicks out 2Amp max not 1A
and cahrging via usb will drain your battery more then it will charge it?
so i dont think modding the cradel to charge via usb will do nothing but drain your xda2 whilst sitting on it as it will be lit up and activesync will be open

The charger is rated actually at 1 amp and for purposes of charging the 2nd battery in the cradle if one had a spare. Thus 500mA or less will charge the unit. It did mine.
oh how come on xpansys their chargers kick out 2A :? :shock:
Just for those without an electrical engineering degree:
Important for charging is the voltage, not the current. Sure, a large charge current could charge the battery faster, but even then only if the charge voltage were high enough. And then, these batteries are highly sensitive beasts, requiring a complex charge strategy - if the current is too high they just blow up! If the current is low, it just takes longer.
The MDA/XDA has an intelligent charge circuit, which is software controlled and most likely senses and controls the actual charge current. When doing a "full blow" charge it probably limits the current to around 0.5 amps (though I haven't measured this), but will decrease this current considerably once the battery gets nearly full (otherwise we would cook the battery).
Aes, you can charge the XDA without problems from the usb bus. The only caveat: check that cable -see above!. I do it all the time and in fact, have often gone into internet cafe's whilst on the road just to charge my XDA (cause the charger was defect).
And yes, you can see if the battery is really charging: if the light is on and the %-age full increases over a few minutes, then the battery is really charging.
ah cool cheers for clearing that up then lol so it does work my bad :\ just thought it was weird how their cahrgers are 2A meaning it will be charged in like 2 seconds like :\ thats what confused me

The rated output is 5V / 2A for the XDA2 AC adapter. My math was a little in error. If you don't have a 2nd battery charging in the cradle, than a 5V / 1A charger would suffice. Howver, it did a great job of charging just thru the USB cable. I can't remember off the top of my head what a USB line is capable of - 500mA??
Sorry for the confusion.
i've got the solution!!!
Hi everyone, i think i have the solution of XDA II not charging on USB port using XDA sync/charger cable... if u want the XDA II charging from USB, just open up the connector and disconnect the 20,21,22 pins from USB bus power line. After that, u can use XDA sync/charge cable in any USB port and they will sync and charge the XDA II.
How i know this??? 'cos i "reverse-engineered" the connection of the cradle... i was wondered y using the same usb port, the cradle can charge while the sync cable can't... so i test all the connection of the cradle and found that pin 20,21,22 and also pin 2 is disconnect. The pin 20,21,22 only connected to power when u plug in the DC into the cradle. This mean that pin 20,21,22 connected to DC (+) while the pin 2 is connected to DC (-) only when u plug in the external DC supply to the cradle.
I've modified my XDA sync cable and now i can charge my XDA II on any USB port even from my laptop. Hope this helps for those who purchased the XDA sync/charge cable to use with XDA II. :wink:
To those who like to go further....
The only problem that i can c now is that if u modified the cable and u use it with a car adaptor, will it charge the XDA II as fast as possible like when u plug in the external DC supply? OR will it only trickle charge the XDA II as using USB port? i really don't know 'cos i don't have a car here with me to try it out... but i think it will only trickle charge the XDA II only...
Therefore, to those who like to get charge faster in the car, u can install a small switch connected between the USB power line and pin 20,21,22. By switching the switch, u can choose between trickle charge and fast charge. 8)

I would be most carefull about this solution. I know that the charge-light will go on, but I'm not sure it will actually charge the battery (just check after 5-10 minutes if the batteries have really charged.
As you noted, the external charger goes across pins 20-22 (+5V) and 16-18(GND). This is where the XDA is meant to charge the battery - and it will do so under any conditions if the +5V is applied here. Pin 13 is meant to power the usb circuitry and it wakes the XDA II up, starting ActiveSync at the same time, it is not meant to charge the battery.
Hi, i've checked and tried on few machines... it really works... trust me... maybe the charging circuit on XDA II is different from XDA???
And as i said in the post b4, the connection is "copied" from the original cradle, so it's absolutely correct unless i did something wrong on my side... but well i've double checked it... :wink:
If u've some time to spare, can u pls check the connection of the cradle as well? it's good to verify so that all XDA II users will benefit from this... Thanks!
Should work, since I only use the cradle without power supply to charge my MDA II. Full or empty doesn't matter, the MDA II always gets fully charged.
Didn't measure the pin layout yet in my cradle.
Upgrading from T-mobile pocket pc phone edition to imate
In reveiewing this thread - it appears that I will be able to use my car charging cradle, and my USB chrger/synch cable, perhaps with some minor pin adjustments.
I would like to know if anyone has experienced any damage/ problems relating to using xda1 accessories with the xda2.
Also, I have the thumb-keyboard, and wonder if anyone has tried using the xda1 thumbboard with the xda2. Would like to avoid re-buying all my accessories if possible. Help is appreciated.

Just to check with you, i am going to test my car charger....are you saying that the +ve needs to be connected to either one of the pins (#20,21,22) and -ve to gnd pins (16,17,18).
Is all the gnd #2,#5, #16, #17 & #18 shorted? and pin#20, 21 and 22 shorted as well?
Thanks. :?:
Hi i've made a "not-so-nice" layout... which i think explained better than myself... :lol:
The lower part showed the connection needs to sync and charge with USB only. The upper part become valid when u plug in the external DC into the cradle. I do think that pins 2,5 is somehow shorted internally.
So, if u test ur car charger, i think pins 20,21,22 should shorted with pin 13 to the power(+) while pins 2,5,16,17,18 are shorted to ground(-).
The XDA car charger shouldn't be a problem to charge the XDA II... it's just the XDA USB sync and charge cable that causing the non-charge bug on XDA II...
Hope this clear all the confusion... :wink:

Hi all,
I'm sure this will infuriate those guys who are trying their best to explain this to us thickies....but.....
I have purchased the L'il Sync cable from eXpansys (from PPCTech I think) and, obviously, it won't charge the XDA-II.
Now I have a soldering iron, and I'm prepared to use it, but I need to know EXACTLY which wires to chop, or where to solder. I'm still having trouble woking out whether to solder pin 16,17 or 18 to somewhere - or whether to cut other wires off. I fact - I don't really know which pin is which!
I know you guys have the know-how - but you need to make it really simple for me to understand!
Please help!!
Thanks,

I am wondering what voltage the Xda car adaptor runs at?
I have a couple of Nokia car adaptors here that run at 7volts, even thought the mains adaptor runs at 5volts.
Is 7 volts going to fry my Xda II ??? :?:
I have a 3rd party combination unit. It has a USB sync-charge cable but also has a mains power adapter and a car accessory socket adapter both with a socket to accept the USB end off the sync-charge cable. So you can charge the XDA II by mains power, car, or USB port on PC.
Anyway, my point is the output voltage of the mains and car accessory socket are both 5.8v
Will 7v fry your XDA ii? I don't know but the cost of a compatible car charger or a 3rd part unit like mine is a lot less than the cost of a replacement XDA II
Ed
On my AC Adapter, it says the output is 5V and 2A.
I'd stay away from 7V, it's nearly 50% more than it wants.

I am really interetsed to know what the 12volt car adaptors run at. If someone has one can they put a meter on it and let me know.
As I said above, the nokia AC adaptors are rated at 5volt, but the car charger gives out 7volts and the nokias seem to survive ok.
I'm not keen to plug my XDA in until I get a reading on the car charger's output..
I don't have a car charger, but I can't imagine any reason why it's output would be any different than the ac charger.
if one are going to measure the volts out of an car chager then it's best to measure it while it's charging a device since volts when there are no amps being drawn are often higher then when the amps are being drawn
the right answer
the correct answer is min 4.8 - max 4.9 volts 2A :lol:
Blackberry micro use chargers are all over the place. do any of these work adequately with our phone? Do they supply enough amps/volts?
Sent from my HTC Desire using the XDA mobile application powered by Tapatalk
without having testet this, i'd assume any USB Charger with an output of 5 Volts and 500 mA can do the job. I am using the original Charger, the one from my Sony Ericsson X1 and also a Sanyo Mobile Booster (Portable Battery Charger). They all work well
Charger from the hd2 works fine too! its all becoming very standardised now
Yeah, it's just I heard that certain chargers don't appear to work very well, with some people reporting that their phone has run out of charge when going on long journeys whilst using the phone as satnav - so using cables which employ the correct ampage/voltage could be important.
The micro USB Blackberry charger works fine on my Desire

i'm using the HTC original charger car charger from my Touch HD, it's 2 amp and charges the phone in no time. Needed to get a mini usb to micro usb adapter from ebay though.

Sorry, totally missed this. I just put 'usb charger 1a' into the search. The seller was 'arygroup'. It's not as quick as the one it comes with but it's fast enough!
The phone says it is charging from USB, whereas it doesn't with the proper charger. Not sure why yet...
I received my car holder with car charger a few days ago, it is labeled as a Moto.V8, and should output 1.5 mAh.
I don't know if it geniune Motorola charger or clone, always a surprise with eBay
Haven't tested it yet, all I hope is that it doesn't drain my phone while I'm using GPS navigation.
I've read some stories that certain chargers can charge, but when using GPS applications they will drain.
There are a couple of other posts about the same thing. Lets try and keep it to one thread. Better for updates etc
For those in the UK sainsburys are doing a 1amp car charger for 6 quid.
It includes two usb sockets, and is white.
When plugged into my desire, the phone reports that it is being charged by AC, and sat nav dosent drain the battery (in fact it still charges.)

From another thread, it appears that the phone will only draw 500 mA unless the USB data pins are shorted together. A few minutes with a soldering iron and the charger works as well as the HTC one.
If you have any old HTC (Diamond etc) 1A chargers lying around just buy one of the Mini to Micro USB Charger Adapter Converters for 99p including p+p from ebay and use them!
I have run some tests on 500mA chargers and would be interested in hearing how someone else has got on with one (instead of a 1A).
At first I was using a 5 Volts & 500 mA Blackberry charger with a cheap micro USB cable and getting very slow charging. At first I thought this was the 500mA rating but then I got a brand new official Nokia micro USB cable and it seems to charge at a comparable rate to my official charger. I'm at a bit of a loss to explain it other than perhaps the quality of the cable has a lot more effect on charging than I thought (I don't think the data connectors have been shorted on the Nokia cable, I can transfer data fine using it)

I can confirm this =P. But you DON'T need to buy a new usb cord, just use the cord that comes with the desire and plug it into the Touch diamond Charger
I had the Touch diamond and Im using the touch diamond charger for this phone cuz it LOOKS way better (when i plug it in, HTC lights up ), and it charges almost twice as fast (Difference is very noticeable)
I was manically driving around to find a car charger, and EVENTUALLY found one at a Vodacom shop(in South Africa). It was made by Body Glove, and it's a 360 rotating device, with a USB port on it. The Micro USB cable that came with it is retractable, but I haven't used it. I used the cable that came with my phone. Will test it later. I drove about 200 plus miles with it, and my charge was good after the trip. My phone is still less than a week old, so the battery charge hasn't quite gotten to where it should be. Cost me about R99 (About $12)
By the way, the Micro USB connector will supposedly be the only connector on phones by 2012. It has apparently been standardized, so that people will just get a phone, but that all chargers will work on all phones. Too much waste from old chargers they say.
Hello. Our college from forum gave us a link to the car holder. Very cheap price and free postage. I found in his auctions on ebay holder + car charger. But im bit worry about voltage: 5V is ok but 2 A?? Maybe this is dangerous for the our DS? Wall charger give 5V and 1A. What do you think? If you don't mind please check this auction for me. CAR Holder + Charger Thank You very much. Cheers.

As long as the unit outputs 5V that's all you need worry about. The phone will control how much current is drawn. Even if 2A is available, the phone wont ever draw more than 1A. Current can't be forced upon something. Only voltage can.
Ironically you may have the opposite problem. The main thing you want to watch out for, instead of damage to the phone, is has the manufacturer appreciated HTC smartphones? I've bought several of these car charger things from eBay, and they've ALL made the same mistake. My phone will only charge in USB mode (limited to 500mA) when plugged into them.
Why? Because the two centre 'data' pins are not shorted out in the car charger. If a HTC smartphone does not see a short between the data pins, it'll assume it's plugged into a PC or laptop and limit it's own charging rate to prevent damage to a motherboard. A motherboard that isn't there! Very few manufacturers appreciate this. If your phone sees the two data pins are shorted, it'll charge at the full rate up to 1A.
Unfortunately there is no way of telling until you buy it. The good news is, if your phone will only charge in USB mode, there is a way round it if you don't want to send the charger back for a refund. Get a spare data cable. Strip back the insulation in the middle. Carefully cut back the screen. You'll see 4 cables; Red, Black, Green, White. It's the Green and White cables we are interested in. These are the data cables. Cut these, and on the side that plugs into the phone, short these wires together. Tape the cable back up with insulation tape AND NEVER USE THIS CABLE AGAIN ON A PC OR LAPTOP! It is now only fit for charging from a car charger. But your phone will now see the short between the data pins and not limit its charge.
An official HTC Car charger will not have this problem.
Oooo than you very much. Fantastic answer! I think we should pin this topic for the rest to easy find. Thank you very much again. Cheers!

Thank you for the good explanation.
Does anyone know of unofficial chargers for HTC phones that have the data pins shortened? I would appreciate links to reasonably priced offers.
I have a spare charger from ALCATEL and wonder if I can use that for my HTC Desire S.
PRI: 100-240V~50/60Hz 150mA
SEC: 5.0V 400mA
I know that 400mA is very little but I hope it will suffice until I find a more permanent solution.
i'm using a chager at 5v/1a for over 3 months, it's ok
but 2a maybe too high~
If You only want to charge Your phone it doesnt matter if You have 500mA or 1A.
But if You want to charge and have Google Maps running You need 1A. Because otherwise the phone will discharge too fast.

You dont have to have a modded cable if your car charger already has the data pins shorted. Im using the motorola rapid charger too and it works fine, it will charge your phone as AC and give enough power to recharge the battery with navigation on. if you want something a bit better you can try this one , they ship to canada. My rapid charger broke so i bought it a few days ago. Reviews says the trident will give around 8-900mA, the moto charger outputs around 6-700mA.
I would only buy a premium brand here. If you see how no name mains adaptors are made... the risk of blowing up something expensive is just too big.
I wnent with the Sony AN-400 / 401, because it is rated at 1.2 amps exactly, is small, and was reported to work fine.
For some regulator disasters:
http://hackaday.com/2012/08/15/buying-cheaper-electronics-and-not-saving-money/ <- a USB car charger without components, putting 12 volts straight on USB.
http://www.youtube.com/watch?v=wi-b9k-0KfE <- teardown of imitation apple mains adapter, showing no output protection and very little gap between mains voltage and output circuit. Good info, but style of presentation is not my cup of tea.
So that is why I went with a premium brand.
that's one charger from one factory that some guy that didnt know what he was doing and ordered thousands, without testing them. He probably went for the 25 cent super deluxe model...
Well reviewed chargers from xda members here and not to mention the hundreds of people on amazon are a safe bet. Here's a 8+page thread on the charger i linked. Your premium brand name sony charger is made in china too.

1. Get a bullet-type 2.1 amp USB charger:
http://www.amazon.com/iFlash-Lighter-Charger-Adapter-Output/dp/B008LM45I2/ref=pd_sbs_misc_7
2. Add a "charge only" USB cable:
http://www.amazon.com/Mediabridge-U...357979634&sr=1-11&keywords=usb+charging+cable
This combo charges a Nexus 7 (which requires even more current) with navigation on!

That looks ok,but I cant find a good quality usb charge only cable that ships to canada :
I have a el cheapo usb charger from ebay and I used my usb cable that came with the phone...and when i pluged it in it switches from AC charge to USB ever couple of seconds back and forth...so I want to try something different.
If you're into rooting and custom kernels, most of them have a fastcharge option where you don't need to have a special usb cable, or, attempt to short the D- and D+ lines.
Monoprice has a 2.1A bullet charger for a bit cheaper:

i cant say for sure until i get it sometime next week but i think so. im in canada too and couldnt find the powergen anywhere that would ship here.
There are some other brands that are good too but i like this one cause it's dual usb like my old moto rapid charger. If you dont need that you can get some smaller ones that will work just make sure they are well review and can output around 1A. The one that bfspider spider recommends is a good bet too since monoprice is pretty reputable store and will ship to canada.

You can try to mod this one in the mean time, just take it apart and attach the two data pins(they are the two middle ones). Solder is best but if you cant you can just use pilers and bend the pins until they touch. i did this with a few of my chargers too and it works to make them AC but it wont increase the output if its low to begin with.

Once again thank you so much.I found the Trident charger here with free shiping to USA and Canada and good reviews
I just bought a "Samsung Car Adapter" with this output: 5V 1A
Is this a good CAR adapter for Nexus 4?
The Nexus 4 "LG travel charger", has this Output: 5V 1.2A
I wan't to use this Samsung Car Adapter while using GPS on the Car or playing games on the Car without lowering the battery.

FYI, this adapter should allow most existing "iPad" chargers (1.2A or higher) + any USB cable to work well with the Nexus 4.
The problem is that Apple products deviate from USB charging standards. As a result, most chargers try to be compatible with iDevices and also deviate from the standards. So when standard-compliant devices try to follow the standards, the chargers refuse to follow the standards, and the devices get upset with each other. Fortunately, they fall back and settle on a lower-power charging rate.
If you want to buy chargers that are very clear on what they support, check out MediaBridge (also available on Amazon).
Why does a bog standard USB cable work in the car for me? Using a proper off-line sat nav my phone was fully charged

So i got that Trident charger that you recommended....the quality looks good...but when I tried it in the 1A and 2A port with the usb cable that comes with it,it shows USB charging but when I use the HTC usb cable that came with my HTC one S it shows AC charging....its so confusing and I just dont get it....that HTC cable is a sync and charge cable.
The generic T-Mobile car charger available at T-Mobile stores charges just fine. I believe it is at least 1 amp. Its black, has a purple white small led indicator when charging. The USB end looks like a little block and the cord is an accordion type and it also has a a female USB slot in it to plug something else in at the same time but I believe whatever USB cord you plug in there only charges at .5 amp. With this charger I can run navigation and Bluetooth and Pandora and message at the same time and it will charge.
Sent from my often RMA'd Nexus 4, So that I can use the one I'm using now when I get the 6th and hopefully final one.
I just dont get it why does it with one cable show USB charging and with the other HTC cable AC charging?:S
