USB car charger

[Lio]

Does anybody charge their TyTN in car via a usb car charger. I use a usb car charger for different devices: Bluetooth headset, gps reciever...
I also used it to recharge my Blue Angel.
Unfortunately I can't charge the TyTN. Has anyone had the same issue?
The charger says that it can charge 1Ampere. The original home charger is also 1 Ampere, so I don't understand why it doesn't work.
Have tried it with two different usb car chargers and both have the same problem: It charges only if TyTN is turned off. When I switch it on then the red charging light turns off.

I had similar problems except I didn't need to swithc the pda. I saw the usb charge couldn't charge completly or it was very slow to charge if I had screen with light or TomTom running.

I solved using a diferent charger, that generates 220 volts. It has 140W and costs around 40 euro.

Do you have a link, a picture or a brand name to this product?

Same problem.
I was told by the dealer that it's a matter o cable (the pins in the cable)
the one sold with the device is fine just to sync and charge from pc, but can't charge through car adapter.
I'm bought a new cable (arriving next week): it's a double cable, one side for pc, other side for charging.
if it works, I'll post..
bye

I'm afraid to tell you that your new cable will not work. You were not well informed. I am sure that it is not a cable problem, but a charger problem. According to me the power output expressed in Amps (Ampere) is not strong enough even though it says that it's 1 Ampere as the mains charger. Those cheap chinese made chargers are not strong enough for the TyTN. That's why it charges when the TyTN is switched off but as soon as you switch it on, the power output from usb car charger is not enough.

mmhhh, I'll wait the new cable, hoping it works ;.)
the fact is that with original cable the car adapter doesn't charge even if the device is off..
same thing with a 220V usb adapter.
only the original kit seems to work..
I'll tell you in a few days

btw: both adapter are chinese ;-)

Nope, Lio is right on this one. The car charger simply doesn't supply enough juice to charge the TyTN. O2 Exec users have had this problem for ages.

I use the charger bought from the Orange shop for the spv c500. Works fine, if a little slowly.

There are strange things happening!

The USB cable should not enter in to the equation as USB is USB and the pins should be wired correctly.

Here is what I have found.

If charging in the car all is ok until the power is cut, then it only charges whilst off until the TYTN is soft reset. This looks to me like there is a software / powercontroller confilct. It is a little confusing but see the scenarios below;

Soft reset TYTN, leave it off. Plug in to cigarette charger, turn TYTN on/off all is fine.
Turn off TYTN and unplug, all is fine, plug back in (TYTN off) will still charge when TYTN on.
Turn TYTN on, unplug, will not charge whilst on anymore until soft reset but will charge whilst off.
This is the same if I turn the ignition to power the lightere socket.

However, another spanner in the works, if I pull out the charger even with the device off and re-insert it it stops charging until soft reset.

What seemd to work best was to do a soft reset whilst the unit is charging and powered on. After that I was able to unplug, plug in even when the unit was on, turn ignition off/on etc... It only reverted back to not charging when I removed the charger from the socket as it was charging.

These are my findings and I presume each charger will be different.

I presume whatever electronics are in the chargers also causes problems. I have tried 2 USB and one fully wired charger and it is the same with all. I know for a fact that at least 2 of them have overcharge circuitry built in but do not think the 3rd has, I also presume the TYTN also has so perhaps there is some conflict here also.

I do know that there are car chargers specifically for the TYTN so will try one of those and see if it solves the problem. (anyone tried one?)

Anyone with more ideas please let us know.

Thank you for this tip. Now I can recharge in car thanks to u! :lol: I tried it and it works.
