Too tired to post pics tonight but not really needed.

I just pried the case apart on my dual charger and the USB socket came out with the wires hanging from the 4 connections on the back of it. I just blobbed some solder on the 2 middle wires to short them and popped the case back together.

All the chargers will be very similar but I would imagine that some of the lower profile chargers would be difficult to take apart. In that case I would modify a cable to connect the 2 data wires together, pretty easy if your carefull taking your time not to cut into the other wires too. Would mean you would have to sacrifice a data cable for the purpose and that it would no longer function as a data cable.

http://www.amazon.co.uk/gp/product/B000U6QPFI/ref=oss_product

Thats the cable that I use in the car, has a handy clip on it so you can tidy up loose wires, and very very cheap too! :)
[Desire Accessories] Rusty!:
As does mine, it's meant to be up to it though, will be using some foil to short the pins in the morning for a further test.
[Desire Accessories] Rusty!:
Pins shorted with foil, Belkin charger still not up to it.
[Desire Accessories] simonf7:
Modified my supposed 1A charger last night, gained 5% battery on the way to work with My Tracks running so constantly downloading maps and using gps - top tip.

I have one of these http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=380227248451 btw.

Update,

I tested the charger this morning on the way to uni, I drove for 30 mins with the phone using navigation and playing music over bluetooth to my car stereo the battery began at 90%. I periodically checked the battery status using snap battery and the phone reached 100% in about 20 mins. At this point the voltage was about 4.1V and temperature 27 degrees. Once the battery had fully charged it began to discharge with the voltage dropping to 4.0V and the temperature raising to 31 degrees. I assume this behavior is due to some logic in the phone with only lets the phone begin charging when it is lower than a specified value.

I'll test again tonight with the phone on a lower starting charge.
[Desire Accessories] catdog:
I have shortened the data pins on Maplin's A50JK currently on special offer for €8.99 and the phone is charging much faster now.

It takes 5 mins to take the changer appart and using extra solder to join the two middle pins on the PCB. I think the same trick with fast charging is used by other phones too (iPhone, HTC Diamond, etc).
[Desire Accessories] daverave999:
[QUOTE ]It's actually the phone that's the culprit. It will only take 500ma when on charge via usb, but will take about 900ma when on ac. By shorting the data pins on the charger you fool the phone in to believing it is on AC charge, so it takes more from the charger.[/QUOTE]

Great info, thanks! I'll do this on my extra mains charger I bought. Need to get another car charger though as the cheap ebay job I bought gets very hot and smells like it's burning...
[Desire Accessories] rob61280:
The Small Maplin charger (A50JK) from the first page seems to work well if you short the middle pins or modify a micro usb cable, I've now tested it twice with navigation and bluetooth audio streaming to my stereo at full brightness and it charges great. I've attached a screenshot of the graph from battery snap and highlighted the car charging with a red box.

[Desire Accessories] ferryrich:
When I've been using mine on long journeys(GPS, 3G, fairly bright screen for 6 hours+), it has indeed been charging, but the icon hasn't been indicating it as such. I've also noticed that it helps to keep the device nice and cool. As soon as it heats up, charging rate declines.

I've just been using a BlackBerry car charger
[Desire Accessories] ros486:
Hi, would it be possible to show your modification by a photo, - and what modification are you doing to the usb cable?

Thanks

Szimnau
[Desire Accessories] Bart1981:
Can somebody please post a picture of which pins to connect to eachother. And maybe a short manual how to do this?

I just ordered a 1200mA charger.... But if this doesn't do the job I need to know how to connect those pins.
[Desire Accessories] Rusty!:
I took a charger apart and soldered the 2 middle pins on the reverse side of the USB port (where it is soldered to the circuit board)
[Desire Accessories] Bart1981:
So somehow you broke the charger open. And at the printplate you soldered the two middle pins together, and after that you put the charger together again with glue or something like that.
[Desire Accessories] zzleezz:
For the people asking for photos of modified chargers, not much point really. Its unlikely that you have the same charger and the job is so simple its a waste of time trying to show you how to do it on one charger when there are so many out there.

That being said here is a simple guide that should cover all the bases (do this at your own risk).

Buy a charger with the correct plug on the end (micro USB) make sure it is AT LEAST 1000 mAh (for those not familiar with the mAh it can also be marked as 1A)

Find a way to open the case, use a flat bladed screwdriver to pry the case open if you cant find any screws holding it together.

Gain access to the wires at the back of the USB socket in the charger. There will be 4, the 2 going to the outside 2 of the 4 connections inside the USB socket are the power connections YOU DO NOT WANT TO SOLDER THESE. The 2 in the centre are the DATA connections, you want these to be connected together. Find a convenient place to solder the connections together, on my charger where the pins came out of the back of the USB socket was nice and exposed and I just blobbed some solder on the 2 middle ones, others have found on the PCB in the charger an easy place to make the connection.

Thats it, put it back together and try it with something not too expensive, I tried it with an old MP3 player.

Alternatively butcher a data cable, strip back some of the insulation and find the data leads in the cable (no idea what colours, use a continuity tester to find which are the data leads) and connect them together. You will not be able to use this lead as a data cable after this, and I would not use it to charge from your PC, only from car/mains chargers.

Hope thats clear enough
[Desire Accessories] Rusty!:
Basically yes, although the charger in question clipped together, so nothing needed breaking or glueing.

Green and white generally, I have done this too, so I don't have to modify any charger I get my hands on to test.
[Desire Accessories] b0yce:
For those who have an existing MiniUSB Car Charger - check out this MiniUSB to MicroUSB Converter at Mobile Fun. It can only be used as a charger i.e. it has the pins shorted already I presume.

Tested in my car with SatNav running and charge icon appeared as expected.
[Desire Accessories] sh500:
So, so far pretty much the only charger that will charge with 'large draining apps' (without any mods) is the official HTC one?

Anyone got a link to a USB-to-micro-USB cable (not converter tips) that will do the job (with a 1A plug of course)?
[Desire Accessories] Marsbar:
Well there's a reason for this: USB devices are only supposed to take a maximum of 500mA from a host.

I know it doesn't help us but I thought it only fair to point this out - HTC are doing the right thing here.
[Desire Accessories] Fon22:
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.)

[Desire Accessories] blackfox888:
Just check my TomTom One car charger, its output is 5V2A. now all I need is a mini to micro usb convertor.
[Desire Accessories] Bart1981:
So who actually does have a sigarette charger which does fully charge the Desire while using GPS??? And which charger is it? And I mean not a modified one...
[Desire Accessories] zzleezz:
There are a few of us that have either chargers or have modified chargers to work in the required way.

http://www.maplin.co.uk/Module.aspx?ModuleNo=267947

That link is the one that I bought and modified as extensively explained in an earlier post - its a very easy fix. All the info is there and its not many pages back.
[Desire Accessories] sh500:
This is what other users have already been doing. I can't find my soldering iron anywhere so am trying to find a charger/cable with no modifications required.
[Desire Accessories] Bart1981:
Yeah I know, but with this Mini to Micro USB Charger Adapter it has allready been done. So no need tot do it yourself.
[Desire Accessories] sh500:
Post (#41) in this thread already describes this.

I'm trying to avoid any add-ons as it doesn't look too good in the car.

I'll try and get hold of an soldering iron and perform the job on the charger end.
[Desire Accessories] k.aalai:
Thought here might be the best place to ask this, since its kinda related, and the knowledgeable members might be able to help!

Went on a trip, and took the HTC usb wall charger with me, the idea being that by just changing the cable, I can charge my HTC and ipod, thereby not having to take the ipod charger as well.

Well, it didnt work... When the ipod is connected to the HTC charger, it shows as charging, but doesnt charge AT ALL. Any ideas as to why? Its an old gen 3 ipod, which I can charge with computer usb, ipod carchargers etc etc, just not the HTC one...
[Desire Accessories] DHel01:
I have bought the following Desire Car Holder + Charger at Ebay:

http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=350344927919

The Car Holder fits perfectly and the great thing about it is: The Charger is a 1.5a charger which can keep up with my Desire's battery needs when using GPS + Streaming radio!

Great!

I recommend this when you don't have a holder and charger yet!

I think this is the one because it looks the similar and its from the same shop:

[Desire Accessories] daveaus:
I got this one from ebay:

http://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItem&item=250632387594

The quality seems really good, although the blue light is a unnecessary distraction.
[Desire Accessories] Bart1981:
Ok it looks nice, but does it charge the phone when using navigation and bluetooth?
[Desire Accessories] iang123:
Charger

Hi,

Been following this thread for a bit now, and I would like to know if there is anything i can do with my accesories. Basically, I am using the standard cable that comes with the desire for charging, and a Griffin dual powerjolt usb charger that goes into the cig lighter. The thing is mine does lose power when using GPS about a percent every 5 mins.Is there any way of altering this setup to get more power? ie taking the power jolt apart and soldering the connections inside? or am i on the complete wrong track there? Or does any one know yet if you can get a charger that will be able to cope with the demand, Will the official HTC one do this?

Cheers

Ian
[Desire Accessories] Rusty!:
You might well be able to mod the jolt.

Take it apart and look at the USB port, if the middle 2 pins on the port aren't shorted, then you can solder them together.
[Desire Accessories] Bart1981:
This charger seems to do the job said a guy on a dutch forum.

He used the Google navigation (GPS and data) and Bluetooth, and his Desire was charged about 8-10% in half an hour.
[Desire Accessories] iang123:
Might as well

Well 2 quid isnt too shabby. Might as well try it. If it doesn't work tis no great loss!

Cheers

Ian
[Desire Accessories] marshalex:
anyone know how i'd go about modding an old nokia data cable to tie the data lines together? i've got one of those mini belkin chargers kicking about (the 1amp ones which the desire doesn't pull more than usb from) and don't have access to a soldering ion :s

edit - actually managed to butcher a usb extension cable to overlap the 2 centre pins and now the desire picks up the belkin charger as charging AC so hopefully with a test tomorrow i'll finally have a charger i can use with googlemaps!
[Desire Accessories] iang123:
That car charger came and can confirm that it does charge with everything enabled WiFi gps data etc. Not bad for 2 quid

Cheers

Ian

Has anyone found a car charger that can charge a desire with copilot running? my battery drains faster than it can charge using official charger.
[Desire Accessories] zzleezz:
Find my earlier posts on page 2 and 3 mate, easy to modify a cable or the charger I got from Maplin and it works great with the phone under heavy use.
[Desire Accessories] alias_neo:
I got a few from a local phone place. The one for the Nokia 8600 works fine, the second one I got for a MotoV8 (V3)? Can't remember exactly, also works fine, however the Blackberry one doesn't work, although I could have sworn it did work at first, but I took it back and swapped it for another Moto one.
[Desire Accessories] dawmuz:
I can confirm the data wire shorting method works wonders in my car with a 1A charger - 10% every 10 min with gps, music, full brightness on!
[Desire Accessories] kmetek:

[Desire Accessories] spud_work:
Could you tell me which £2 charger are you referring to please? As on the previous page of this thread there are 2 ebay links to 2 different chargers both costing roughly that amount and I want to make sure that I get the right one!

THIS

http://www.amazon.co.uk/gp/product/B002C3AFHG/ref=olp_product_details?ie=UTF8&me=&seller=

I have a couple of USB cables in the car so I can use it to charge my phone or connect to my TomTom.

Works really well and is rated as a true 1000mA
[Desire Accessories] Aleemz:
I have this one and it will not charge my HD2 with Bluetooth running (connected to my Audi car phone), so just pulled it apart and couldn't find any solder in the house :(

I know I have some, but where !?

Oh well, never like reading studd like this then going to bed without having the job done.
[Desire Accessories] Kameo:
Please can anyone confirm that this one will work because it looks so great.

I mean, will it charge even with bluetooth and gps on?
[Desire Accessories] Aleemz:
I carried out the mod today, and it's now charging my HD2 great! Only one problem remained; the green LED on the charger was a big distraction, particularly because my car instruments are lit by red LEDs.

Luckily I had an old charger that I'd already used for spares, and it had a red LED that was the same size as the one in the Maplin charger. A few minutes later I had a perfect match...
[Desire Accessories] sh500:
Great job, looks like an integral part of the car now.

Are you saying that it works well with power hungry apps too?

EDIT: sorry just realised you have modd'd yours to work, thought it was an original one.
[Desire Accessories] Aleemz:
Thanks, that was the aim, to make it look like it came out of the Audi factory with it. Now I just need to buy two more chargers for the rear passangers and find two more red LEDs.
[Desire Accessories] DaaT:
So is it confirmed that this item can charge the Desire while using GPS/Navigation?

h**p://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=350344927919&ssPageName=STRK:MEWAX:IT#ht_500wt_928
[Desire Accessories] Aleemz:
I've been using this charger on my HD2 for a couple of days now, and I think I should confirm what others have said - not all USB leads will charge your phone when it's running under load.

I tried a Nokia lead and while it charged the HD2 with bluetooth running, as soon as I started the GPS (tomtom) as well, the battery started to discharge.

Then I tried a Sony Ericsson mini USB lead (supplied with my X1) with a mini-USB to micro-USB converter lead from ebay, and the original HD2 lead. These charged the battery with bluetooth and GPS running together.

The Sony Ericsson X1 mini-USB lead is much thicker than the HD2 and Nokia leads.

HTC HD2 Nexus One Desire Legend Car Charger Micro USB

Working without any problem :)
[Desire Accessories] Kameo:
So this one's confirmed too by Daveaus through PM :D
[Desire Accessories] daveaus:
I just a bit of a test on a 25 min drive.

Battery was at 92% at the beginning of the journey.

With copilot running, wifi on, listening to music over AD2P it went from 92 to 94 over the 25mins.

Although I don't really trust the battery meter because it went 92 - 100 - 93 - 100 - 94...

Overall this charger seems like good quality although I doubt the claims of it being OEM.
[Desire Accessories] blud7:
I use Motorola car charger, works great.
[Desire Accessories] nzdcoy:
I must state this, there are some cheap brand chargers out there that state 500mA and 1000mA on them, but the voltage regulator inside wont let more than 100mA out. these were prices at roughly $4nz+shipping.

To get it working properly it cost roughly $2 for a new regulator. If you know what you are doing, its a simple modification. my 1000mA conversion has been working well with immaterial losses in charge
[Desire Accessories] TrueTenacity:
Does anyone know how to get the Maplin charger outside of the UK... That one seems to be the best available but Maplin won't ship outside of the UK...
[Desire Accessories] MattSid:
Sorry guys but I'm noob about this and I would be sure to make no stupid choices: I'm interested to take a car cargher like this:

http**://images.maplin.co.uk/300/a50jk.jpg

Which technical data should have?
[Desire Accessories] TrueTenacity:
If you had taken a moment and read this thread from the beginning you'd have seen that the charger you are talking about is probably the best charger you can get for the phone...

Get it, Mod it, Love it... ;)
[Desire Accessories] MattSid:
Mod it? how and why? :eek:
[Desire Accessories] TrueTenacity:
That charger and most chargers out there are built and designed to USB spec which will put out 5v and 500mA power... but to charge the phone you will need to tell the phone to bypass the USB spec and pull the full 1A that is available which will provide the 850mA required to charge the phone.

To do this you need to open up the charger, it just pops open and then find the usb connector and solder / short the two middle (inner) pins together.

This tells the cellphone that it is NOT connected to a normal USB port and that it can pull the full 850mA...
[Desire Accessories] leecavturbo:
any chargers tell the phone to go into car panel mode?
[Desire Accessories] TrueTenacity:
as far as i have found out, there is the official dock from HTC that can tell the phone to do so... but otherwise no...

But there are a few apps out there that can emulate the functionality...
[Desire Accessories] leecavturbo:
only a matter of time before someone suss's out what tells it too.

i think someone said 1k ohm resistor across middle usb pins?
[Desire Accessories] TrueTenacity:
No... that'll fry your phone and the usb plug...

The dock function is triggered by an extra pin in the connector...
[Desire Accessories] Jpcurrie:
My eBay mini time micro convertor kicks in the car panel when used.
[Desire Accessories] leecavturbo:
Got a link?
[Desire Accessories] MattSid:
I don't got the instruments for solder and I'm too noob for do something like that, I would prefer to find a charger that could push even 850mA without any mod. I was looking on eBay but I can only find the Voltage but no info about the mA (http: //cgi.ebay.de/KFZ-Ladekabel-Auto-Ladegerat-HTC-HD2-HD-mini-Desire-/390230625914?pt=Handy_Zubeh%C3%B6r i'm interested in this for example), how I could be sure if this work? :o
[Desire Accessories] TrueTenacity:
I have bought 4 chargers from ebay and have had no luck with any of them...

unfortunately you will HAVE to mod it, or maybe find a friend to mod it for you...
[Desire Accessories] MattSid:
Sounds odd to me, why I have to mod it? there's no one that can bring 850mA? :confused:
[Desire Accessories] TrueTenacity:
It is a WORLDWIDE standard that USB ports work on 5v and 500mA... if you want the usb port to put out more than that you will have to mod it...
[Desire Accessories] MattSid:
I'm still confused sorry...why so there's this charger (http ://cgi.ebay.de/Auto-Mini-USB-Adapter-12-24V-HTC-HD2-Legend-Desire-/320561813742?pt=Handy_Zubeh%C3%B6r) with 700mA? it wasn't 500mA the standard? :confused:
[Desire Accessories] TrueTenacity:
That charger either already has the "mod" done or is marked 700mA but only puts out 500mA...
[Desire Accessories] MattSid:
Maybe, there's even this by Belkin (http: //www.belkin.com/IWCatProductPage.process?Product_Id=489767) and it's officialy 1A, I don't think a famous brand will lie, or I'm wrong? :p
[Desire Accessories] TrueTenacity:
I don't mean to burst your bubble, but last weekend I spend $20 on an "Official" BodyGlove charger that is supposedly rated at 1A and it also does not put out more than 500mA...
[Desire Accessories] MattSid:
I understand.

There's someone here with a not-modded charger that works really well?
[Desire Accessories] TrueTenacity:
The phone must get at least 850mA to charge... so unless you mod the charger IT WILL NOT charge your phone...
[Desire Accessories] jamesep:
I've just bought one of the cheap car chargers off ebay, rated 1000mA. The middle two pins were already soldered together so the phone recognises it an AC Charger. However after trying it out yesterday I'm disappointed.

The phone's running the latest LeeDroid rom and at the time Car Home, Navigate plus the GPS but after 30 minutes the battery was down 5-10%.

Obviously, the phone isn't pulling/receiving the amps it requires. Is there a program to see how much is coming through? I've looked a I can't find one.

Also, would anyone be able to tell me how to confirm the maximum Amps for the charger? I've attached a few images for anyone wanting to be creative in Paint.

Thanks

I just use my 3rd party Griffin charger from my previous iPhone accessories and then put on the micro USB cable and everythings working fine and charging as normal car charger USB would.
[Desire Accessories] _Crusoe_:
Went into maplin's just a fortnight ago as I wanted their mini charger to mod as I was driving to Somerset and wanted my Desire to provide sat nav and music (via the headphone jack and into the stereo) along the way. Unfortunately it was out of stock so I bought this:

h**p://w*w.maplin.co.uk/Module.aspx?ModuleNo=390581

for £6.99 used it all the way from London to Somerset with Google maps (GPS+data), mixzing and a bit of Bluetooth on all the way. Worked perfectly, charged and maintained the battery the whole time no modding required.
[Desire Accessories] MattSid:
I just bought a mini usb-micro usb adaptor for mine old 1A gps charger, seems that works fine but I got a problem. When I connect the Desire says that it's connected to a PC, and so I can't load anything on sd card :( why?
[Desire Accessories] jamesep:
The phone recognises it as a USB charger so based on your "connect to PC" settings it's probably defaulting to disk drive. Change the default to charge only and that should sort it.

Just remember, the phone won't pull any more than 500mA as it thinks it's connected to a PC.
