Car charger not working anymore used previously with 9100

[adebilloez]

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

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.....

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!

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.

I have repaired actve sync and it seems to be ok now. I have no idea what happened.
