I'm not quite sure what your trying to use to power it but the voltage must be between 4.75 and 5.25V otherwise its gonna get a bit upset!

I want to use BT-338(http://www.globalsat.com.tw/english/products_detail.php?main_id=20&p_id=74) car charger
On AC power supply of this device are writen +5V 1.2A i hope that car charger will be the same voltage?

The car charger will give out the same voltage but I would put a voltmeter across it anyway just to check and also to confirm the polarity as this could well upset the XDA! The highest amperage across a USB bus is (I think!) 500mA but a 1.2A supply will be ok as the device will only pull what it requries. Don't try and power both devices off the same charger though (just checking this isn't what your trying to do) as there won't be enough power to go around.

I was just thinking about doing something like that. How much power does the BT mouse require? Given the XDA can be powered from a standard usb connector it doesn't require more than 500mA. So do you think 700mA aren't enough for BT mouse??

I have no idea to be honest! I havn't used it but it would be worth checking before trying!

barnesdmd: thanks working fine

It "should" be fine to power both off a 1.2A supply (although i dont know if the car charger will be able to supply this or not. mains - 5vDC is very different electronics to 12vDC-5vDC). The worst that should happen is that the GPS needs a large power supply, and the voltage supply will drop (what happens if you draw too much current) The Wizard should then just ignore the useless voltage (below 5v) and not be worried by it.
This is all should and not will, i dont know what components are fitted in the Wizard charging & power circuit.
I haven't tested it personally but do have a reasonable knowledge of electrics & electronics

Can anybody here who has a GPS bluetooth mouse have a look on it's specification? There we should see how much power it requires, so we could be sure

Best car charger for Kaiser?

As the title says!
I need a car charger and i don't know what to buy...
i wanted something that can last at least 6 months without having the cable damaged due to stretching

I use the cable of my TomTom One XL. Same voltage...

I like using my ebay-bought USB adapter and retractable mini-usb cable. Cuts down on the mess, and lets me charge other USB devices.

I use Motorola OEM that I got long time ago (4 years back with my first RAZR) - It works no problem
I also use regular USB cable with my wife's iPhone car charger and works fine too... So I guess Blackberry charger will do the same since I use Blackberry as home charger too occasionaly

Note that many of the miniusb chargers will not work consistently. Elsewhere here on the forum there are extensive details, but in short, HTC compliant chargers (meaning will charge 100% of the time) short pins 4-5 on the mini usb port. This is not implemented in normal mini usb chargers. The normal (non-HTC compliant) will usually work but not always.

Read about a small percentage that seemed to have trouble (RLOD related trouble) from cheap or non-HTC chargers, so I got a true HTC OEM at www.tiltdepot.com. Best $25 I've spent.

I have used a tomtom car(borrowed from my mom) charger too, wich is 2.0 Ah, but found out the HTC charger (same 2.0 Ah same voltage) charged a lot better than the tomtom one. After one hour(started with a 3/4 charged battary) the tomtom was pretty much the same(3/4) and the HTC one was fully charged.

Yep... With the TomTom charger I believe the charging current is limited because the HTC phone sees it as potentially a data connection. The HTC charger has short between pins 4 and 5 addresses that. Hard to beat the HTC charger.

The "11 Foot Heavy-Duty Cord" is nice... it's coiled tightly, and long enough to get to wherever you need to in the front of the cab, be it a center console or a seat. The digital display tells you how long it's been charging, and changes color when still charging the device (blue is standby, orange is charging). Nothing beats the Naztech for a USB car charger. I have the silver one, but it looks like the newer ones are black; you can probably get your choice of either if you get one off of Ebay like I did.
They have lots of other cool products for phones, too.

eXpansys Deluxe USB Desktop Cradle for HTC Touch Pro.
You can now use your 220v adapter and sync your pro at the same time

Haanyone found a cradel that can charge, sync and also charge a second battery. This is what's missing from the Touch pro range of accessories.

The above cradle can do all that, im not sure where it charges the second battery but expansys says it can

From the picture looks like the back is some form of lid, perhaps there is a battery slot under there
Steve

I've pre-orderd the cradle. I will let you know of it can charged a second battery.

Just checked with Expansys, and it is pre-order only. they expect the cradle to be in stock by the end of september. And i can confirm that it does have a second battery chargering slot.
Rich

I will definately pick one of these up. Im wondering if it is waise to wait until a week or 2 after it comes out for a proce drop or some aftermarket ones?

Did anyone get a random offer for this from expansys? Seems legit but its some sales rep writing you personally tellin gyou to order from him. Seems fishy

Did anyone already recieve one of those?

Just ordered my TouchPro craddle from http://www.devicewire.com
They had the craddle in stock and kindly threw in a couple of complimentary HTC lanyards. The price was £35.94 including UK 17.5% VAT & £6.77 next day shipping. This was a little cheaper than Expansys where the total cost would have been £38.47

It dosent charge a second battery... it looks smart but it dosent charge a second... waste of a good opertunity... rather annoying...
I suppose (for me anyway) it is a good addition to my desk as when I pick up the device to make a call I dont now get the disconnection sound notice in my other ear from the sennheiser mono head set that I use for my skype to landline calls... if that dosent make sense call me on skype (justin0679) & I will gladly explain in more detail...
Regards,
J
PS. I am very happy with DEVICEWIRE - a helpful supplier

Has anyone found a cradle that works with the Sprint Touch Pro?

I have got one from Expansys.
It can charge your pro & your sencondary battery.
the 2nd battery can put under the lid.
it also can plug in a 3.5mm earphone, so when you charge your cellphone, you can listen to the music at the same time.
and the led show you whether they're fully charged.
very good device, but a little bigger than i think.
that's all.

Anyone tested this cradle with a TV-out cable?

Hi seeker-lover,
Perhaps there are different types. Would you be so kind as to reply with a link pointing at the spec of your craddle. Below points at the unit I bought from DeviceWire.

Hi,
Expansys sell both an official HTC cradle and their own brand version. The official HTC cradle "CR G300" cannot charge a second battery. It does have a 3.5mm stereo jack for plugging in head phones or connecting to your amp to play music from the handset. It is a tidy looking piece of kit albeit prone to finger print marks.
The expansys TP cradle can charge a second battery as you point out. You can find non oe TP cradles on ebay which sell for a lot less that the expansys asking price for its own brand version.
Rgs,
J

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...

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:

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..
-Chalrie

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!
