dear all, i bought a car to usb adapter recently, hoping to use it to charge my atom exec when driving. but sad to say, it doesnt charge my atom exec at all. but it works with my ipod n other usb devices.
does anyone hv any idea why car to usb adapter cant charge my atom exec?
thks alot in advance!!!
cheers
Hi,
I find that by turning the phone on and then connecting the usb, it works ok. the led should turn red (atom exec) if it is working. If I just plug the phone into the usb car charger it does not work.
cheers, Richard
(i think this thread is in the wrong forum, should be accessories)
I had the same problem with my Atom. I think you need the car charger to output 1A as I have tried a couple with 500ma and it would not charge.
by default, all other USB charger could not charge the O2 because they are NOT designed to charge a WINCE. Have you ecer notice that even you plug in your WINCE devices to a USB cable connected to your PC without installing a correct driver, it won't charge your WINCE?
thks all for e replies...
i had discovered the reason behind why the usb charger is not working for pda phones. its bcos the voltage is too low to charge the pda phones.
now i had bought another usb charger with a higher voltage n it works!!! so for those who want to charge their pda phones using usb charger when driving, pls rem to get RAPID usb charger. only these RAPID usb charger works with pda phones.
enjoy!!!
cheers

Good morning !
I have bought a Qtek 9090 and a retractable Ziplinq USB cable.
I can sync my device, but I am unable to charge the main battery with it.
Does anyone know something about it ?
Thank you.
Could be a faulty cable. If it doesn't work after a soft-reset, I would send it back...
Best Regards,
Mr.G
maximum current draw from usb is 500 milliamps, xda2s takes twice this to charge
Same Problem with PDA2k
I bought a similar USB retractable cable for my smartphone and it was working perfectly, charging and sync'n. When the PDA2k was released, I had one of the first ones, and I could only top up the charge if it was about 75% charged, anything below that would drain at the normal rate.
I am not sure it is the USB current, as I was in Singapore the other day, testing a BlueTooth GPS device with my PDA2k, which was running at lower than 30% charge, the shop keeper offer me a USB sync/charge cable to keep running, and it worked!
I don't quite understand what happened but I suspect that the current of the USB outlet was the main cause.
Hello,
I've got my TyTN in europe (ROM 1.18.256.104) and my "usb" car charger is not working (charge sometime but ONLY if my TyTn is switched off....not usefull for GPS...)
I've tried another one same problem...restested with my 9100 : ok .
Is it due to the charging load ???
Anyone experiencing the same problem ???
Cheers
André
If I remember correctly the 9100 used an 800mA charger and the TyTn uses a 1A charger. That could be your problem.
hello,
same problem, but charging work on laptop (normally laptop is unable to offer more than 500ma).
I've read an article with C500 where charging work when pin 4 of the usb cable was linked with gnd. Is the same problem with Tytn ?
cheers
Tom
yep, had the same problem too with a standard charger with usb cable.
the charger output was 500mA. it stopped charging after a few seconds.
Recently i bought a Brodit carholder with the charger included. This charger has 1000mA output and its charging without problems.
So you need at least a 1000mA(1A) charger, otherwise it will not work well.

Thanks Luminus for the Reply, But are you sure there is no electronic part added on this car charger ? :?
Strange enough, both my car charger and USB Mains adapter (1A output) (which I was using for O2 Mini and Dopod 818Pro without any problem) was charging fine on my Dopod 838Pro, but the unit had a problem and I was given a new unit. This unit now does not work with my car charger nor the USB Mains adapter.
Looks like a trip down to the service centre again!
it was a cigarettelighterplug adaper with a usb output, with a regular usb/miniusb cable. the adapter was 500mA.( input 12V/output/5V)
it was a complete kit. you could use it for anything you want.
I only attached the TyTN to this adapter.
the adapter couldn't hold it, the amps exceeded the 500mA and stopped loading. the adapter still works on other devices.
the brodit has the same type of adapter, only with a fixed cable on it and 1000mA. this works perfect.
thats why i think that you need a 1000mA one to get it charging.
Hello,
Perhaps true perhaps not...
I used an official Qtek charger -> 1A ..it work
But not sure that due to the 1A because tried to use a self powered USB Hub and it work too ... I will check the official Qtek car charger (if nothing specific)
I use several chargers. i notice that sometimes, if a charger will only charge the device when switched off, i soft reset the device and then it will charge when on. strange problem. the problem of not charging when on, also occurs with chargers that for sure have over 1 amp.
Same problem here......tried to use the mini usb charger I got with my Leadtek BT GPS mouse......
Sometimes it will charge.....sometimes not....
Problem seems to occur when I switch the device on....ie receiving a phonecall or a textmessage....
It then stops charging only to resume after the phone goes back into stby mode....
Weird.....
Danny.
I have the same problem. I have HTC TyTN and 1A car lighter charger with normal USB cable.
Charging from normal, regular charger works. Charging from computer's USB works. Charging from car adapter works only sometimes.
I've tested about ten different car chargers, including one 2A - still nothing.
I've done factory reset of TyTN - after reset it was working for two days.
I have installed only few essential for me programs and no tweaks.
Cable is tested and working.
It makes no difference if I connect device turned on or off. It makes no difference if I reset device connected.
I have no more ideas...
I kept having the same problem but I think I've solved it.
I went into a T-Mobile shop and bought the 'official' car charger for T-Mobile SDA/MDA and I haven't had the problem since.
I've no idea what it's current rating is, because it has no relevant markings on, but it does get pretty warm in use!
help
I am really confused.
I have the sync wire that came with my device. It has stopped working as a charger from the laptop and I can;t active sync. I can however, de-activate the usb link and use the cable to activate my phone as a modem for the pc, so in theory it works at some level.
I also have another lead which is a compact one and it is giving me the same problem.
Both worked until this week so it isn't a case of them not being compatable.
Any ideas. I depserately need to sync. I can charge from the plug so thats no problem.
ahh
I have repaired actve sync and it seems to be ok now. I have no idea what happened.
1. Turn off your hermes.
2. Plug car charger to hermes.
3. Turn hermes on. Phone is now charging.
This works everytime for me.
Place this on sticky?
My hermes charges off a el-cheapo USB charger I bought for my Orange C500 years ago... without turning on/off
Lucky you. But to many of us, our hermes do not charge but the way I describe, works for me on all those cooked Rom.
Hm. I just plug mine in too, and it has a cooked ROM....
this works for me on AC charger. Also sometimes works after going into and out of standby a few times.
same here. i just plug mine and im good to go..
Ditto. I think you might have a problem with your charger or phone.
hi guys,
don't know if you've seen it or not, but the car charging problems were explained here:
http://forum.xda-developers.com/showthread.php?t=277742
It's to do with the 4th and 5th pins in the plug of the standard car chargers.
Thanks to PhilipZ and tadzio for figuring it out
They've saved me from the annoyance of constantly having to restart the unit while plugged in.
I PLUg it in then do a soft reset and if u use the speaker phone option u have to do it again i used cooked rom also the phone has a fu_ked problem with the car charger
I've yet to find a USB source that DOESN'T charge my 8525...
Currently used:
USB from PC / Laptop (duh)
USB from Playstation 2 and 3
USB from cable box
USB from HP Printer
USB from iPod adapter
USB from Razr charger
USB from blackberry charger
USB from HTC Charger
USB from Razr Car charger
I think the only USB I haven't tried is on my Nintendo Wii.
Hermes charging from car charger
I have a similar problem with my Arkon, powered car cradle, it charges if the screen is blanked off but if I try and watch my satnav it turns the charger off. I'll try turning off the Hermes before connecting the charger and let you know
I have x01ht, i plug charger on 220V AC to charge my Phone. My phone and battery is very hot( about 40 degree). Then i plug charger on 110V AC to charge my Phone and battery isn't hot. Now i understand why my phone is hot when i plug charger on 220V AC
i have this problem with an ebay car charger, if you dont restart the device before plugging it in it wont work.
ive seen the fix for it just too lazy to change it.
Weird Car Charger Problem
I'm running an i-Mate JasJam with Schaps 3.60a, and after reading all the posts about problems with power output and USB pin configurations, thought I would play it safe and buy the 'official' i-Mate car charger.
However, when I first used the car charger, it wouldn't charge. Then I found that after a soft reset, the charger worked perfectly but as soon as I had synched with my PC, the car charger stopped working again.
My view is that this is a software problem and my workaround has been to use bluetooth for synching, and the USB for charging only. I have been using this configuration for the last few weeks, with no problems either on the mains charger, or in the car.
Cheers
yea same here i just plug in and go

I found out by accident that there is a modular car charger that works with HTC just fine. The beauty of this charger is that it has a modular design: the plug (body) itself that goes into your car socket (12V) and a standard USB cable that plugs on one end to the body and on the other end - to the phone.
It works without any problems on my T-mobile Dash, Cingular 8525 and HTC Artemis. The other important positive moment - it's just about $5 at the internet stores. For example here: http://www.cell-phone-accessories.com/usb-charger.html
There is no reason why a car charger would not power your Hermes. The Hermes does not recognize the difference between a wall charger and a car charger (there is NO difference).
car charger, Arkon cradle and hermes
Hi, well I can happily report that I can now use my satnav on my hermes, as long as I remember to turn off the device before plugging in the Arkon cradle and car charger, I'm a happy bunny now

Got the same problem. Every so often my jasjam will refuse to charge from the car charger and will need a soft reset. When it gets into that state it will:
Charge from the car charger while the display is OFF
Not charge from a car charger while the display is ON
Charge from a wall charger with the display on OR off
After a soft reset all is back to normal...
my phone seems to charge in negative direction (discharge)while wifi is switched on ,i use 5v 2amp local charger.,another observation i made is while putting it to usb charging of a desktop it charges properly while even with wifi being ON ,my rom is Prophet_S4V.19701.01_Clean, i wanna know if you have orginal imate jamin or o2neo prophet charger what does its volts and amp say it should be like 5 volt 2 amp or 5v 2A ,
although here charger does seems to be the culprit but does your battery disacharge while charger being plugged in and wifi is being used and power set to always ON ,because desktop power is like 5V 500MA.
if your phone discharges too while charger being plugged in and wifi being used with skype or youtube that would means battery drivers problem plz check when you find a chance.
Hi everyone, hope someone can advise.
I have a UK TG01 and it works ok but overnight it wont charge from the mains charger but it charges via usb.
I have tried different chargers and an old HTC mini usb charger with a mini to micro adapter fitted but its still the same.
I have the Mugen 1300Mha battery but its the same with the standard battery on all chargers.
I have cleaned out both the charger plug and the socket on my TG01 just in case of dust but no good it only charges via usb.
I have hard reset and flashed the standard UK Orange rom but this makes no difference.
Does anyone know whats going on? it was fine, no changes or software loaded and one day its fine and the next day it wont charge??
Any advice would be gratefully received, thanks for reading.
Faulty USB sockets i think try send it back to Toshiba for warranty repair.
Not sure about that as my TG01 does charge if I plug it into my laptop, this would suggest the socket is ok?
I believe that the charger is faulty, try a new micro usb charger, or try another socket

Agreed. As the TG01 is charging via USB, then there is most unlikely to be an issue with the uUSB socket on the phone.
To tell the TG01 to go into charging mode, the uUSB connector on the charger must have the two data pins shorted out. This is the equivalent effect to connecting to a host laptop or PC when connected via a USB sync and charge cable.
If you have a non-standard charger or are using an adapter from eg. mini-USB to uUSB it is very likely that this will not be implemented.
A few questions...
- Are you trying with the supplied Toshiba charger ?
- If so did it work OK with this before but not now ? [likely duff charger]
- If a 3rd part charger, again has it ever worked ? [if not then probably missing the required pin config]
Hope that is of some help.
Hi Kevin, its a genuine Toshiba charger and I have been using it since day one.
I took my charger into work today and tried a friends Nokia micro usb charger and that worked first time so duff charger.
No, I asked him to try my Toshiba charger and that also worked
So I assume my original charger possibly may not be 'shorting' correctly or presenting exactly the right resistance to the TG01 or possibly my TG01 is getting a little fussy about how it charges.
Anyway I have ordered a genuine Nokia charger from ebay and fingers crossed all should be well and thanks for all the advice everyone.
