Anybody come across a USB travel charger for the XDA II? I have the USB cable just need a charger that outputs 5v and between 1 and 2amps and has the usual US, UK, EU, Aus and NZ attachements. Expansys.com have one but outputs 5.5v - not sure if that will damage the battery, proporta.com have one also but outputs 9v! Why these chargers don't stick to the standard 5v is beyond me.
not sure what you mean but usb in this context
the connector in the buttom of the xda2 is not a usb connector
and usb cant provide more then 500mA
If you have a usb cable for xda 2 you can acquire a lighter adaptor into which you plug the cable, this will give the correct voltage.

Some power adapters come with USB sockets - I think it should become a standard so with the same cable you can get power from laptop/cigarette lighter/mains. Ericsson used RJ11 cables (modem cable) for it's mobile phone chargers but it never caught on.

Thanks for the link, I have two of them already, looking for something to plug into mains.
Mark,
I think I know what you mean: A plug (either 12v in-car or 110V/230V mains) that supplies just +5V DC on a USB socket.
Received one with my retractable sync'n'charge cable from time168.com (but those guys dont exist anymore).
Also received two with my BT GPS from DConnex.
I would say they are for sale on eBay, at least with the sellers that supply these sync'n'charge cables.
I made an emergency charger myself based on USB: 4 NiMH AA cells (1.2V each) in a battery-holder & wired to a USB socket. Not pretty, but good enough for emergency.
You might want to look at www.javoedge.com. They have a USB retractable sync/charge cable and you can also get adapters that allow you to plug the usb cable into a US/European/wherever plug socket adapter.

I had a look at those - they're not really travel chargers just US and EU chargers and a bulky adapter for the UK.

That sounds like a good idea. Proporta.com have a 9v charger
http://www.proporta.com/F02/PPF02P05.php?t_id=940&t_mode=des but I was thinking AA batteries would be easier to get in an emergency.
Since I only know basic electronics I used 4 rechargeable NiMH cells that gice approx 4.8v alltogether. With normal (alkaline) AA cells you probably end up above 6V. I would not try that . . .
Setback of my solution is to have an AAcharger with me for longer trips.
About the travel adapter: The usb travel adapters I have came in two flavours:
1. Car cigarette lighter use
2. Mains use. I also got a number of 'plugs' with it to make the adaptor fit a variety of mains wall outlets.
I have a tomtom bluetooth gps receiver that I used to use with my xda-ii for my satnav solution. I had a car charger that charged the xda and tomtom unit at once. I have now upgraded to the Exec and am hoping to find a similar car charger but couldnt find any on google/ebay - does anybody know of one that exists?
Thanks
Allan
Cannot be of help, but looking for the exact same solution. I had an iMate JAM and a cradle that charged that (mini-USB) and had an output for TomTom Bluetooth. If all else fails I could try taking apart the adapter because it has the correct output, just the Exec won't fit in it!
assuming the TOMTOM gps receiver uses a round 5V center positive connector to charge it ( which it almost certainly would do )
then check out my posts in this thread,
http://forum.xda-developers.com/viewtopic.php?t=29351
the cradle even comes with a wire just for charging BT GPS receivers
Ouch! Thats a little pricey!
I already have a mount that holds the unit, so I am just looking for a calbe charger solution. Anyone have any links?
Thanks
Allan
in that case I have seen a car lighter plug on ebay that has a USB socket in the back, it was on £3~£4 you could then use a regular sync and charge cable to charge it
o2 shops are now stocking the car charging lead... complete with natty o2 shaped blue indicator!
To get round the problem of daisy chaining mounts and receivers, I got a great car charger - dual usb adapter from eBay (I searched for "dual usb car") which gives you 2 usb sockets for about £8 all in. Having bought this though, I'm thinking of installing a spare cigarette lighter socket behind the dash to power it from and cut down on cables in the cabin...
Funnily enough, the many Sync and charge cables for the Sony PSP would be able to simultaneously charge both a Jasjar and a bluetooth GPS unit
here is an example

Universal charger- special
The Universal as well as the Typhoon, Wizard etc. need special wiring for the mini USB. when connecting to the computer the the driver is activating the proper pins in the Mini USB socket and you can see the "charge" light on. However when connecting to a USB Poer Supply, pins need to be manipulated (some to ground or perhaps to Vcc). I'v looked into this issue many times (searching in the Internet) and could not find a proper wiring diagram. although I know for sure that they are exist as there are some Car working chargers offered for Universal / Typhoon.
In any case refering to this thread, a car charger that works for Jam/XDA2Mini most probably will not work for the Jasjar/Universal unless i is apecified as a Universal car charger.
If any of the memebers has come a cross a wiring diagram for Typhoon / Universal charging scheme it is appreciated if you could provide details.. as many of us would like to build their own car charging units.

Dude, what are you talking about !! I use the sync lead from my kodak camera to charge my JJ from my laptop it works fine but is slow (my laptop hasnt got much umph) and the same goes for the PSP power lead I mentioned earlier, I use that in the car with my cradle that happens to have USB sockets in it, (pictured in another thread)
It seems that either your usb lead has the proper connection to fit the requirements of the JJ or I am doing something wrong that I am not aware of.
Here is the test: Just take a Powered USB Hub, connect XDA1, XDA2, XDA Mini, XDA2S (all the models that I could test right now) and It seems that the Powered USB Hub can charge these devices.
Now connect the JJ (I suggest with a traditional USB syc cable that comes with either ..) and NADA I got no indication for charging .. than connect the HUB to the your computer which has the ASYNC installed and you see that immidiatly the JJ is being charged. Both feeding measured at 5.15V.
The Typhoon behaves the same for me as well.
Further more, I have few USB chargers (other than the one equipped with the JJ) which is in fact a PS with a USB port . The result of connecting the PS through the traditional sync cable is "No Charging".
The same applied to many Car USB charger that I'v tried.
Perhaps your Kodak sync cable is special (in fact I am looking for the schematic diagram of a cable like this)?.
I tried (just now again) also with Dopod 828 and it seem the same (no charging unless it is connected to the computer).
Please double check your charger cable and try th sync cable that comes with the JJ.
I dont see why kodak would have used a special sync lead, because on the kodaks it is used for data only (power comes in via a diffrent connector) when I get a chance I will buzz out the cable for you !!!
PS I think you shold plug it in and wait, mine starts charging instantaneously when used with the mains adaptor which has 1 Amp of current available, but takes a min or two to start charging when I am using my laptop/in car charger, both of which only have 500mA available.
Car Charge
From reading other threads, Pin 4 in the Mini USB is shorted to ground and that's probably turn on charging ..
I suggest that you read threads about the power charge / car charge in other forums... here is an example I took and although it talks about the Typhoon it is relevant to JJ as well and it suggest to connect pin 4 and 5 to ground. I can't have a good explanation why your JJ starts to charge after 2 monutes. I suspect that it has nothing to do with the current that can b drawn from the PS.

Here's what I've found on modaco.com forums, posted by richwookie on Oct.4 2004:
QUOTE >>>
...I've hacked open my C500 mains charger (quick, where's the superglue), and sure enough there are only 2 wires leaving the box to the mini USB cable, GND (black wire) and VO (white wire). However, after very careful probing, with a very tiny probe no less, I've established that the GND wire is connected to both pins 4 and 5 of the mini USB connector.
Now usually pin 4 would be not connected to anything as pin 5 is normally GND. So next I probed the C500 data cable to see if pins 4 and five of the mini USB were connected together. They weren't of course.
So what does all this mean?
Well, from what I've discovered I conclude that the C500 will only charge if:
1) There is data on the line (even if it isn't saying anything :wink: )
OR
2) Pin 4 of the mini USB plug is grounded.
So what's the solution to making the generic car chargers work?
Do nothing to the car charger. Mod the data cable so that pin 4 at the 'mini' end is connected to ground.
This IS all speculation and I suspect that it is easier said than done. I haven't yet hacked open my data cable, but I expect there are only four wires in it, and the only way to ground pin 4 (mini end) is to somehow bridge them at the connector. I think that is beyond my soldering skills (have you seen the size of the contacts on the plug?!) but I may give it a go anyway.
Anyone else want to try? Let us know here.

Posted from my SmartPhone while it is charging in my car using a 1.49 cigarette lighter USB adaptor and my newly modded C500 data cable!
I'll let you know if it still works as a data cable when I get home. ;-)

Modded cable doesn't work for data now.
When I connect it to the PC it just charges. I suspect that when the phone is in 'charge from adaptor mode' it inhibits the data lines.
<<< UNQUOTE
Well, I guess it's simpler to mod a USB cable, than either carry around a charger, or install Activesync everywhere.
With all this chat about modifying pins etc call me naieve but why not just buy a dedicated charger from expansys or an o2 store ? both cost between £10 - £15
:shock:
Just an observation I have made... I have an O2 EXEC, and charge it quite happily (sort of) with the Standard USB Synch cable and a Car Lighter Socket USB thingy.
The only thing is... It will NOT charge if the EXEC is on (screen lit up) when the USB lead is connected or power connected. Switch the device off, connect the lead, and the charging light comes on.
I find the same when I connect it to the computer with the Synch lead too. It won't connect to ActiveSync or Charge if the EXEC is on when connected.
Hope this helps.
can anyone confirm that it takes a way longer time to charge a device via car charger or USB? why is the device unable to charge via car or usb once fully drained? Any Solution?
USB standards allow 500mA per port whereas the standard mains chargers output somewhere between 1A and 1.2A therefore USB is slower, also below a certain point there isn't enough power in the battery to fully power the device such as the phone section, bluetooth, Wifi, SD cards etc, and USB power levels don't contribute enough to this. The solution would be to get a USB -12V car adapter that supplies over 1A which should do the job.
Is there a way to charge ya phone through the USB as quick as it would charge through the mains?
It takes for ever to charge through USB?
No. Because USB hub doesn't have as much output as charger.
I know standard usb gives 5V
how much does the wall charger give??
I have a freeloader solar charger, and don't know if I can use the 9.5V output on my desire.

It's not the Volts that's the problem its the Amps
The wall charger provides 1A, a USB connection provides 500mA, so half as much.
Ok thanks people
Never tested never heard about but maybe a Y-cable (2 standard A plugs on one side, a micro USB A on the other side) is what you are looking for. It provides the 500 mA from two individual USB ports. However, you have to make sure that both ports can supply 500 mA individually and simultaneously! E.g. a passive USB hub will not work since all USB ports have to share the 500 mA from the host PC. You would need a powered USB hub.
Get a cheap USB cable extender.
Cut it open.
Short the 2 data wires (white and green)
Tape it back up.
Use this in-between your normal USB cable and your USB port.
Hi,
I have just bought the galaxy nexus and am wondering if any of you bright bods could think of a way to do this. I have a Fiat bravo with blue and me so use the usb port for media playback, however this does not supply enough power to keep the phone charging if using navigation too. I also have a 750mA 12 volt charger. Is there a cable that would allow me to have both the media player cable connected and the cigarette lighter cable connected at the same time, preferably with d- d+ shorted so that high speed charging would be available as the effective power available should be 1.2A if my thinking is correct
