Build a charger for your Touch 3G

Hey guys. I have had a few PPCs in the past but the Jade is my first SmartPhone. I like to charge my PPCs in the car as I use them for navigating. I use a universal holder plus I dismantle one of these

as they are easier to wiggle into any dashboard gaps you might have. They are pretty readily available on eBay, but note that they tend to have pretty low guage wire and aren't configured as twisted pairs so it is pretty hit and miss using it to transmit data but it seems to have no problem transmitting DC current. I have used this for very long trips using devices that pull about 1A of current and the cable doesn't warm up so I presume the resistance must be low enough for charging purposes.
Simply connect the other end to a USB Car Charger and you are nearly ready to go. Connecting it up this way will trigger charging but I suspect the device assumes it is connected to a PC as it turns the screen on when you connect it this way as apposed to the Wall Charger where the screen remains off. Careful using USB Chargers designed for other devices (Ipod etc) as they have configurations which may confuse / damage your device. I found this out the hard way when I connected my Jade to an Ipod USB Car Charger which caused all sorts of grief with an undetectable microSD card, the device refusing to turn off which although is now resolved, I am still uncertain whether I haven't caused some damage
So how do you convince the Jade to charge from your Car Charger like a Wall Charger? Well first thing to be aware of is that devices that implement USB charging have various methods of detecting a connection to a Wall Charger as apposed to a computer. As I have mentioned, the iPod (and my old iPaq) uses a resistor configuration between the Ground, 5V and Data Pins to tell the device that it is connected. Fortunately the Jade is much simpler. I have determined from searching the web plus attacking my Wall Charger with a multimeter that all that is required is that the Data Pins are bridged and that the Metal Socket Surround is connected to the Ground Pin (which it is anyway in most Generic Chargers). All that was involved in mine was opening the Charger, finding the middle data pins on the circuit board and dropping a solder bridge between them. Make sure you buy a good quality USB Car Charger that is easy to dismantle (mine was held together by screws) and can provide at least 1A.
Enjoy

My previous phone was a palm treo pro (htc panther), for which i bought a sprint car charger (micro usb). The first charger that was sent to me was heavily used, so i complained and got a new one. After i returned my treo, i got the jade and decided to sell the new charger and modify the old one (which was working fine, except the connector didnt connect properly) to charge the jade. So i opened it up and soldered the two (+ & -) wires to an old usb extension cable, so that now i have a car plug with and usb(-a) socket slightly standing out. When i connect my mini-usb cable for the jade only the charging led lights up.

What did you do with Data Wires? If you joined them together then you have achieved the same outcome as a solder bridge.

Nothing, i just cut them as short as i could. They dont connect to each other...the outer ground isnt connected, too...

Is it really necessary to pay the premium price for a 'genuine' charger?
The device charges from any USB port, so any car charger designed to power mini-USB socket devices should work, should it not?

Any USB charger will do the job.

I found with my 500mA charger, that while navigating for a long time (2 hours), my battery still drains..
The original HTC charger is a 2A charger, that can keep up charging while navigating.

Very interesting find there! I just ordered a Brodit kit for the car and this time round, I went for a active one so I just slot the phone in and it charges.
I will have to find out what current it gives out because I would potentially use navigation especially as I am recently finding the Audi one can be really crap!
On another note, I bought a premium HTC original one - it lasted all of a month and bearing in mind I must have used it 3 times in total...Was shocked!
What I found was that I had to hold it in a certain way to charge however, it was NOT the charger and it was NOT the phone.
For example, the charge worked fine on a Diamond1 but not 2.
For example, the phone worked with USB cables so its not the port.
Let's see how the brodit kit goes!

so can i use my old xda orbit charger and i have an old usb car charger adapter that was for something else so can i just stick in the td2 usb cable into that and charge it, i am just a bit overley concerned as i had to send 1st td2 back as it only held full charge for 45mins and i dont know if i damaged it by using wrong usb charger

I (we) have the HTC CC C100 USB Car Charger.

Nice and beautiful charger. We use it for my HTC TD2 and her HTC S310, earlier I used it for my TyTN II too. In my car there is a passive Brodit holder for my TD2.

I've a car of "premium" mark, so there must be a premium charger.

Black-Rose...where does your "premium-mark" have its charger connector? I consider mine to be "premium" too but the location of the cigg. plug is in such a bad location !
OK I have heard from Brodit this morning - very short and straight to the point reply:
Thank you for the mail.
Cigg plugg ca. 800 mAh
Fixed installation 2A
I don't have time to get it done properly in terms of the fixed installation and no doubt it will cost a lot more too for the product. I'll see how the 800mAh goes with navi too...if it's bad, then I'll have to invest in the HTC cable again and hope it works this time.

i use HTC CC C100 as well, which came with my Polaris. it works fine with both my last Nike and Topaz now.

OK Ended up telling Clove to cancel the Active holder and change for Passive
Just not worth the risk if Im lacking that much in the charger/current
But I got the new HTC C100 today - works fine with the phone

Car charger Modding

I noticed a few complaints on this forum and others about Goggle Navigation being too much of a drain on the handset even with it plugged into a car charger.
My suspicion is that this is down to badly made car chargers, and on a previous occasion using the Testing menu, I noticed that my own charger was being reported by the phone as USB.
So I set about trying to rectify this, using my awesome rolleyes knowledge of how the phone recognises what it's being charged with and an 'I don't care if I kill the charger, it was free' attitude.
I took it apart and tested continuity between the 2 middle (data) pins on the USB plug, there was none, and the problem was identified. I simply flipped the board over and soldered these 2 pins together and reassembled the charger.
Took it out to the car, plugged it in and lo and behold, the Testing menu now reports that it is plugged into an AC source! As my phone is fully charged and I don't have any trips planned right now I don't know how much real world difference there is, but it's looking promising, at least the phone now knows it can draw 1000mA instead of 500mA, and for 5 minutes 'work' it was worth doing.
I didn't bother with a how-to as I figured chances of someone having the same charger as me were slim, but pics aren't a problem:
Here is my universal USB charger with the cover removed:

and the reverse side with the 2 pins soldered together:
Probably doesn't tell you a huge amount unfortunately, but to be honest that's because it really is a simple procedure with not much to tell.

where did you get your universal charger? I'm wanting to chop one up and hide the nexus dock on the side of my GTI instead of blocking my 6" double din monitor..
Almost like you can do your radar detector..

It was an Xmas present, part of a universal kit. It's made by Mountech if it helps though.

thanks I'll look it up, hopefully most universal ones are designed the same usb wise then I could dremel my dash and have a easy access usb port for nav.

Fail!
Despite the mod, it's still not enough to charge/sustain the N1 with Google Navigation running (screen on full brightness). Guess it's just not man enough to produce the required 1A.

I have a USB port installed in my car as per the headunit
at full brightness and while using google navigation AND streaming Slacker via bluetooth... I do not have a -% charge
in fact, the N1 stays fully charged at all times... (however if I have less than 100%, it does take a long time for the % to go up... might take 5 minutes for 1% increase)
sooo I'm not sure what the problem is with the car chargers (as I don't use one)

I have a USB headunit and never thought to try and charge from it! D'oh!

DI, Igo and power ratings.

I have and igo with the microusb tip and my DI is headed home soon. I was checking stuff out at the store and I got a long lecture about how power ratings can be different. Clearly verizon sales reps are better than electrical engineers. Anyways so the power ratings on the igo happen to be 4-5w, does anyone know what the ratings on the DI stock charger.
Even better if anyones charged their DI using Igo, how is that working out?
My fuze used to run a little hotter than usual on the igo.

The HTC charger that comes with the phone is just a little stub that plugs into the wall with a female usb connector on it to accept the micro usb cable that ships with the phone.
It outputs 5v at 1 amp.
Here's a photo of the charger:
(the part that's obscured by the flash says 50-60Hz)

I have an iGo charger as well and was planning to order a tip for this phone. Is it the A97 tip? The iGo site doesn't have the Incredible in their system yet.

very nice picture, thanks for the detail. the igo is rated at 5 watts so its perfect for this. and yes i think a97 is micro usb, however there are many micro usb tips and all of them work. easiest way to make sure is just carry your phone when u go get the tip. unfortunately i have left my tip in the car so i cant say for 100% but the packaging reads A138 which is another microusb. on monday i get my phone so i can hook it to the car and verify.

Has the A138 been working for you? I ended up getting a few A46 tips instead of the micro USB tips because my local Radioshack had them on clearance for about $2.50 a piece. The micro USB tips were $10.
The A46 is a female USB-A connector so it will work for pretty much anything that uses USB, provided you have the proper USB cable to connect it. I got a few 1.5' micro USB cables from monoprice for that part of it.
I haven't used these enough to notice if it's charging significantly faster/slower than the stock charger, but it seems to work fine. I wish iGo would publish the specs for all the tips (amps, volts, etc) instead of just listing compatible devices.
