Please Help: Problems with charging!!

:?: Hello. I was wondering if anybody has had same problem as i have.
I work on my xdaIIs a fair bit away from home and as a result i need to recharge it every now and then. I have a usb charger cable that i use to charge it using other computers and also via a usb car charger pluggy thingy sorry cant remember name :lol:
The problem i have is that while i am charging my xdaIIs using this method the battery power starts running DOWN as if the power is being drained!!! The device is definately telling me its being recharged.
Please help... I have no idea what is going on???!!!
THANKYOU in advance. 8) :?

Depends what you are using to charge I had the same problem with a mini sync cable I bought sync'd fine but didnt charge but that because it was designed for an XDA not an XDA2 bought a new one from boxwave and its fine.
But certainly if your device is sufficiently drained it will be pulling more power that your PC's USB slot will be willing to give it so you could be running into that.

I would guess that the charger doesn't supply sufficient current to actually charge the unit. I say this, because I have seen exactly the same thing (= orange light on and the battery power level decreasing fast) when I built my custom charger for XDAII. XDAII is very "picky" and needs a lot of power to charge and the "USB car charger", as you described it, probably can't supply enough.

Thanks for the reply guys.
It used to work when i first bought it but now doesnt.
Any ideas on what i could purchase that WOULD work??

I have had a similiar problem with a similiar charging setup, but mine charges fine as long as the battery level does not fall too low, if it gets below about 30% then it seems to decharge instead of charge... its really strange.

Cigarrete adaptor charger Draining mine too..
I had a Ipaq 2210 installed in the handle bars of my bike with a Holux BT GPS, recently after breaking 2 of them( IPAQS) I've replaced with a XDA IIs, I had a cigarrete adaptor for the IPAQs and another for powering the speakers... as now i can't use the speakers (due to the horrible 2.5 jack)I've modified the supplied connector for charging without the craddle to fit the connector for the speakers...
I realized from time to time the XDA turned it self off... and last travel it just died with the orange led on and battery 0%....
However first time I've used it was a 700km trip (paris - switzerland) and that time had no pbm (once or twice it turned off but that was all)
I've noticed that the supplied wall power adaptor is a 2Amp one... which looks like enourmous to me... but i tought that cigarrete adaptors were not amperage limited (but for your battery and generator/alternator)
One think I havent tried is to cut the Ipaq's one and fit the connector there... as the Ipaq uses the same wall power thing perhaps the cigarrete adaptor will be the same too....
Please any advice for me ??
I would also like to mod the suppplied connector into a usb stand alone sync cable (pls advise on it too....)
Also i would like to fit an Ipaq IR led onto the XDA to use it as remote for my digital rebel camera.... (advice again?)
Thanks in advance

Charging a TMobile MDA PRo in the Car

Hi, I have a TMobile MDA Pro and i have purchased an in car charger so that I can use it with TomTom satnav unit, slight problem, unit does not charge when in the car. Bizarre, as when I use the standard USB Charge & Sync cable with PC happily syncs and charges with no issues. Anyone any ideas, does there have to be a specific setting on the unit to enable it to accept charge via the cigarette socket in car?
Many thanks

I found that to charge the universal, pins 4 and 5 in the mini USB plug need to get joined together - by default pin 5 is not connected to anything (well, wasn't in the cable I had). I've made that modification, and am powering a couple of devices of of a 2 port hub in the car.
Cheers,
Steve

Hi, sounds like a problem I am having and meaning to ask about.
I've got a USB cigy lighter adapter and tried plugging in the sync lead to provide power when it's in the car. So if I have my Exec in standby the charge light will come on (I think it charges sitting on the today screen, but not to sure) but as soon as I fire up tomtom the charging light goes off....
Does this sound like your problem, or are you not charging at all?
I'm interested in finding out what I need to charge the Exec while it's running tomtom? Anyone have any ideas?
Cheers
Matt

I'm pretty certain that I didn't get a charge light at all with my cable until I modified it, then it works, as expected, including in TomTom.
To confirm what I've got is:
- A Ciggy to USB socket adapter
- A two port hub plugged into the adapter
- Modified cable into the hub (along with an unmodified cable connected to my BT-77 GPS unit).
Plugging the cable (prior to modification) directly into the adapter, rather than the hub, didn't work either. The Brodit all-in-one adapter/cable worked fine (and I still have it intact, but not in use), but if memory serve, pins 4 & 5 appear to be connected. I used a multi-meter to try and find out why that one worked, and my combination didn't.
All of this stuff is wired in behind the centre console, so I've not got any unsightly wires, or anything.
Cheers,
Steve.

I think you need a car charger that can output 1000mA to charge the Universal. Same requirement also for an AC charger. 1000mA is what's important. Cheers

Hi, We have had quite a few customers with this issue, we advised and they have opted for the brodit active mounts which have the inbuilt cig chargers and it has cured the problem, or for the neater solution they went for the Molex hardwired versions to stash the cables behind the dash area,
The codes are: 968649 for the cig charger version or 971649 for the Molex hardwired version, http://www.dsldevelopments.com/brodit/holder/T-Mobile+MDA Pro-Brodit-Holder.asp
Hope that helps, drop me a line if you need any advice,
Thanks again

Found 1A 5V car adapter
this is the only place I found off ebay that has a 1A car adapter
http://cgi.ebay.co.uk/CAR-CIGAR-CIG...4QQihZ006QQcategoryZ15329QQrdZ1QQcmdZViewItem
It works fine on my MDA Pro, just need to plug it in while it is off for it to start charging.. if turned on, then pluged in, then it won't start charging.
I even have an 800mA adapter, but that doesn't help the MDA Pro, it needs more power!

Hi there Bryson
The items you quoted are actually the charger and the holder for the PDA. I also notice from the link you provided that there are 2 cig chargers (items codes 942625 and 942650). Can I know what are the differences between these 2 models and would either of this chargers charge the Universal while it is running a navigation software such as TomTom or Garmin Que?
Also, do you ship to Singapore?

Where can I buy a working car charger for the Exec?

I would like to get a car charger that works with the O2 Exec when I am running navigational programs such as Garmin Que and TomTom. I have tried more than 5 chargers but no luck thus far.
If anyone has any to recommend, do let me know. I am located in Singapore.

i use my car charger from my gps that is the Holux 236, the only think i have to do so that it starts charging is turn it off on the button and the led will change to orange, i have tried one other charger that has a usb plug and it worked fine ! So has long as it has a usb plug you'll be alright and if you do not find one look for the Motorola car plugs that it will probably work on Uni since it has a mini usb plug

The charger from M3000 works fine with my Uni
And the Motorola Mini-USB chargers doesn't work...

Hi, I found that this issue is connected with proper usb cable not with charger itself (usb mini have 5 connector but in some cables only 4 are connected and in some other cables all 5 are connected and so are the difference). I was also trying many chargers and no luck. But I ve tryied charger with other cable and suddenly all chargers start charging my jasjar.
Anyway, the bad thing is it stops whitout any reason so now charging jasjar in my car is a real mystery for me.
regards,
Piotr

Be careful if buying one with a double USB output - I bought a few different models hoping to power both Exec and the Holux GPSlim-236, but all failed. They would power the Exec, but as soon as the Holux was connected, it would always cause the Exec to continually reboot - fortunately "soft". Make sure the supplier will take them back if it doesn't work.
Try a car charger with a USB socket on the end that takes a separate Sync/Charge cable.

The problem is, the exec is very power hungry, especially when the batt is dead !! you need a high current charger at least 1A (1 amp) the charger used with the blackberry (I forget which model) is suitable as is the genuine exec charger obviously.

use O2 Atom car charge
O2 Atom car charge will work with O2 Exec as well as A/C charger from Atom

Exec/SPV car charger...
Got an o2 branded one today for the Exec/Mini - works like a charm (Charges my SPV and runs Tt at the same time) but cost me £14.99 for the privelage!

could you post a link to the website? I would love to purchase one but am currently located in Singapore and so far all the charges don't seem to work for me.

Car Charger for UNI - how to make working
Hi All!
I've also tryed 2 diferent car chargers and 1 USB Pluggable Car Charger (some noname chineese 3-rd party) with 3 diferent cables, and one 3-rd party AC Power Charger. They ALL worked strange.
I can confirm that to make them all work I should:
1. Switch off the Universal;
2. Plug in the chgrer in to Universal;
3. Wait until the Red Light on.
Now I may turn the Universal On, and see the "Charging" battery status.
The reason and how to fix:
As you may see I used different adapters. All they have from 0.5 to 1.0A output circuit. But, the USB ports I used with my laptops have only 0.5A output and always start charging the Universal.
So, I dont think the output power is the reason.
The most likely - it is the "5-th pin" issue, which is mentioned above here. Can somebody provide information about power connection for the Universal?
It seems the solution is about to interconnect/short circuit 2 wires in the car adapter' cable to make the Universal charging in a usual way with any of my (your) "non-working" car adapters.
Also, I've noticed, that in a case the battery level around 30% and I plug in the "non working adapter" and no red light and system not is in the "Charging" state -- the battery is charging anyway!
Also, let me remind you about another issue that the Universal have: Active Sync (older versions) would not sync (USB Device not recognized error) if you plug in the Universal if the power is On.
To workaround that you have to switch off the Universal, plug the cable and after that you could successfully sync. The same symptoms? May be the same reason?

I would advice anybody not to mess with interconnections in USB, I mean stop soldering and checking because its shortest road to bricking Your precious jasjar. It can be done with proper cable and you have to find the right one ;-)
Secondly - I found that jasjar Rom is also responsible for charging issues. As I stated earlier I finally found good usb cable but later on I lost an ability to charge Uni. in the car. After upgrading to the Aku3.2 rom it start to charge immidiatelly. Same charger and cable - one time it charge, second time it dont. So additionally to cable theres something with soft with preventing Uni. from charging.

man why is it such a complicated issue to get the universal to charge? and it seems that this charging problem only happens to the universal and not any other device, am i right?

YESSS! I Have upgraded to on of that Aku3.2 recently! May be it is the reason! But, my original Power adapter still charges my Uni so does the USB conndction to the laptop...
To ALL: Could you please confirm that you can use third-party adapters with the older ROMs?

hopefully we can get some updates soon.

Are all chargers alike?
Are all chargers the same? I would think that the USB power rating would be the same. So, I should be able to charge the Jasjar using a charger for a Motorola RAZR (if I weren't so afraid of blowing up the Jasjar)

Please sell me your car charger

I have been trying to get hold of a working car charger for the Universal that would charge the phone while it is running navigational programs but to no avail.
If anyone has any for sale, do let me know.

The car charger costs barely $5 in china and on ebay. It can be purchased from anywhere. I use the car charger that i got with my Holux GPS reciever. I have a lot of car chargers. This is how they work. You plug in your USB cord into the car charger and the car charger goes into the cigarette lighter in the car. I am not selling mine. Go get one from ebay. Just search on ebay for USB car charger.

I have done so and the thing, its either I'm having bad luck with them or there's something wrong with my phone. The best I ever got was that it charged the phone when it was OFF but when I switched it on, the charge disappears.
I tried using my GPS's car charger and another USB Car Charger as well but they both do not work and I do not know why.
I have spent so much searching for the right car charger which is why I am so desperate now just to get a second hand one that would definitely work.

I think you'll find this has been discussed here before, try searching.
FYI, I used the charger from my Holux GPS, and whilst it works, it dosn't charge whilst using TomTom. If you try a long trip with this setup, you will find that the battery charge drops. This charger is good only for topping up the Uni whilst not in use. I use the genuine iMate charger and this does run TT and charge at the same time. You need the higher amperage of the iMate charger.

Nope, my car charger works fine in charging the Universal while in use and turned off. It just charges a bit slower while in use and thats quite an obious reason.
Only thing to consider is how much the output levels are of the car charger.

Thanks for your input guys
I have done my research on the car chargers and from my understanding, the only reason could be the shorting of pins 4 and 5, or something along those lines. Other than that, I have tried out various models of chargers and they do not work.
For those who say you need a higher output, I have tried those rated at 1000mAh which is that charger output for the wall unit. This charger connects to the USB cable yet even when I tried a couple of types of USB cables, it still did not charge the phone.
I also used a lower output of 850mAh and it worked fine with the cables tested abouve, so it shows the cable had no problem. But it could only charge the Universal when the phone was turned off. When switched on, the phone does not even charge, not even in the least bit and I am not sure why. Surely 850mAh is more than enough to get it charging while on the navigational (TomTom) programs because when I connect my Universal to my laptop to charge, I am still able to run TomTom and that charge is only rated at 500mAh.
Thus you can see why I am so frustrated with all these charges. If any of you are able to point me in the direction of getting an original chrager online, I would be more than grateful for your help and guidance. I also wouldn't mind buying a third-party charger as long as it works perfectly with the phone when running nagivational programs.

This is the one i have. works brilliantly, charges universal and BT GPS reciever and lets me use my copilot navigation software.

Well, I can only guess the 1000mAh you tried may have been defective???
My car charger is the iMate genuine car charger. This rated at 1000mAh and works great. It charges and runs TT6 no problem. (well, that was untill it packed up the other night so I'm sending back under warranty) But it did work great.

Poundland have a USB car adapter that works perfectly with your USB lead to charge the Exec - works fine on mine!

re: car charging problems
just one thing to ask: are you a smoker?
I only say this because i use a usb car charger and it only charges faster than it drains if you are careful to blow/clean all the fag ash out of the socket in the car to get a good connection. Otherwise the charging led sometimes comes on but cant supply enough power to charge quicker than my universal drains its battery

I have used a Belkin one, one that I bought for an iPod that has a standard USB socket you can plug any cable into, and a cheap ebay one.
They all work, BUT.. you have to plug them in when the device is off. Once the charge light comes on, you can turn it on, and it will charge, although slowly.
If you plug it in while the device is on, it will not start charging.
I don't know why this is, but considering it's the same on all 3 chargers, and I have seen people complaining about this on the Universal a few times, I think it's just the way things are.

Yup because at first i was wondering too why my device isnt charging. Actually the charge light on my GPS came on quicker than the Universal.lol... i had to wait for a few moments and kept trying till the universal began charging. So yeah you gotta wait with the universal shut off.

I have not bothered reading all the replies but the problem with most car chargers is the AMPS, the voltage is right @ 5 volts but the amps is usually 0.5. Ideally the universal needs 1 or 2 amps, the new tomtom standalone units use 2 Amp USB car chargers and are a direct fit for our universals !!! isnt that convenient.

I don't have a charger as such but I use - strangely enough - a sony psp usb cord that goes through a USB cigarette adapter picked up from a poundshop here in UK ( a shop that sells lots of cheap gadgetry - for the non british of you )that also has a connector that is exactly what is needed for my fortuna bluetooth . it works fine . I realise that it does not recharge the phone but keeps it charged . I've not tried the usb to usb mini through the usb lighter adapter though . I guess that the trick its to have a charged universal before you leave on a trip .

I found I was having trouble charging my Universal with a USB adaptor in the car. The "charging" light would only come in if the phone was off, and while it would stay on when the phone turned on, it would not actually be charging and the damned thing would eventually run out of charge (I drive lots).
I eventually realised that if I turned the screen brightness down to it's lowest illumination whilst charging it worked fine. Obviously not much power comes out of the socket...
Now my battery has packed up due to another issue, but turn the screen down and it should be fine.

Voltage Regulator 5v / 2a /
I have read with interest all the comments and solution here and thought it might help to add mine what I have made and fitted to all my vehicles is a mini USB power supply, simply cut the pc plug from a mini USB lead and add one UA 78S05
VOLTAGE REGULATOR 5V / 2A /
http://www.donberg.ie/descript/u/ua78s05.htm
Connect the input leg to 12 v dc bolt the regulator to a GOOD earth/heat sink (car body) and off you go up to 2 amps @5v BUT DO TEST WITH VOLT METER BEFORE CONNECTING PPC

TyTN won't charge with car charger??

Hi,
I recently bought a car charger (actually, it's a 3-in-1 kit, with USB-2-miniUSB cable, plug-in car charger, and travel charger). This set seems not to work with my TyTn, but work perfectly with other HTC pda's - Touch, Cruise etc. However, that cable works nicely when plugged to PC.
Anyone have a clue? Maybe, I should change some power management settings in the TyTN?
Thanx

Hi,
I have the same problem.
Sometimes is charging O.K. (when the screen is off and Hermes is in Standby). But if I have a Phone Call, or if I use the car navigation, charging won´t work.
(Everythink was O.K. with WM5, I think, but WM6 and WM6.1 has this problem on my Hermes - I tried many ROMs, now I use CRCs PHKv12r9, Radio 1.47.30.10)

Get an inverter from Maplins http://www.maplin.co.uk/Module.aspx?ModuleNo=48723&criteria=inverter&doy=3m4 for £19.99 you can then use your home charger...

Ah OK scratch that idea I didn't look at the flags before posting...

I have one, but the question is, why car charger won´t work.
I use the inverter with everything up to 300W without any problems.

I dont understand WHY people have this problem.... I bought a CHEAP little car charger that allows me to use a usb cable. I plug in, leave for a minute or so and it starts charging. Make/ recieve calls, use GPS software and never have a problem. I would say that the charger was made good BUT its a generic "made in china" charger.... Must've been BLOODY LUCKY to find it...

I had this problem with mine, sometimes it would charge, other times it would need to be restarted before picking up the charger? This was using the same sort of charger that plugged into the lighter socket, then the USB-to-MiniUSB plugged into the charger.
I started using a spare charger for a TomTom One which worked perfectly.

In fact, I have 2 car chargers to which I plug USB-mini cable, both not working. I just wonder why... Can it be hardware or software problem? I suspect you all use WM6.... OK with WM5?

I can't find the post now, but there have been a couple of discussions about the charging issues with the TyTN. My TyTN is very picky about the charging cable. It has something to do with a requirement that the data pin in the USB cable either be connected to something live(like a computer) or that the data pin be jumpered to the ground pin.
I have tried a number of charging solutions and keep going back to the AT&T store for a charger that works. I have an external battery for my laptop from Battery Geek, Inc that has both a USB port on it and a mini USB charging cable. Both don't work with my TyTN but work with my wife's Wizard. Actually they work with my TyTN about 2% of the time, just enough to make me think it is going to work.
Someplace back in the archives I've seen a description of how to modify a USB charging cable to work with the TyTN, but I can't find it right now.
