I had a BIG problem with a third party battery charger (RIMAX).
It is a Car charger and a wall mount charger, with USB plug and cable, but IT WORKS ONLY WHEN THE WIZARD IS ON! If the battery goes down for some reason and the phone couldn't turn on, you're lost! :evil:
So, the lesson learned is: before travelling without your original charger check if the one you have could charge the wizard also when is OFF and not only in stand-by mode!
I also have a strange issue with a third party car charger - after plugging in the car charger I have to switch the universal off then on again to make it charge...very wierd!
I've also got one of those, though would prefere one with a bit of cable in the middle to reduce stress on the connector.
Have you checked the amp output on the chargers. They're probably putting out 0.5 amps (USB spec). If you look at the wall charger that came with the wizard, it puts out 1.0 amps. That's why when your battery is completely dead, the 0.5 amp charger can't put enough juice into it to get the battery up to a high enough level.
Actually, according to the USB spec, a device is not supposed to consume more than 100mA without being recognized by the USB host. That is, the USB host is only going to give your phone 100mA until the phone says, "hey, i'd like 500mA, please!"
Sometimes manufacturers may shortcut this and just allow the port 500mA at all times, but a standards-conforming one won't.
This MAY be part of the reason why we have problems charging a completely dead Wizard -- it's only going to get 100mA until the device has enough juice to wake up and request more.

Ah! - That's the problem I had yesterday - had left my Vario on with TomTom draining away the battery and forgotten about it on Saturday night, had just spent the day moving house and everything was in chaos and had no idea where the charger was.
So when I realised it was dead on Sunday whilst out in the car, I plugged it into the car charger that came with my GPS unit, which I have used to charge the phone many times before - but it would not charge, no light, nothing!
When I got home all I could find was the mains charger for the GPS and a USB cable - tried both and none would put any charge into the phone.
By this stage I was shi**ing myself that the phone, which I got mainly for GPS for travelling around Germany in June, was DEAD - with 3 weeks to go!
of course later in the day, once I had eventually found the proper charger, it took a slight pause after being plugged in and then the little orange light of joy came on and brought me salvation!!!!!
I suspected it might have been something like the previous poster said but not being very technical I really didn't know!!
Thanks.
I've had the same frustrating experience. When the battery is very low or dead the only charger that will work is the original adapter, not the car charger or cradle or pass thru my laptop. As I result I have to carry the original adapter whenever I travel and I often wake up with a dead Wizard if I dont realize how low the battery is when I park it in the cradle.
Very frustrating. I dont understand why Boxwave doesnt use a beefier adapter connected to the cradle.

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.
Great Lio,
Glad it worked. When you get a chance, could you pull out the chrger from the lighter socket as it is charging and let me know if it then stops charging again. I just want to see if the same happens to you as it did to me. It will work again once you soft reset whilst plugged in.
Thanks.

I believe this trick should go to FAQ.
A week ago I visited a lot of shops trying many mains-to-USB charges to no avail. I already had one for MP3 player that didn't work too.
After reading your post, I connected the original charger and SRed. Now that another charger works!
Can't imagine what's the reason but it really works.

Same here.
Is this a bug in the software ?
I found this : http://www.expansys.com/product.asp?code=138248
I think it should work fine, I am not sure.
"I found this : http://www.expansys.com/product.asp?code=138248"
Could you contact them and ask about its power rating and whether it is susceptible to the problem/bug?
here I am again.
finally I got the new cable and... surprise... IT WORKS
I used it without soft resetting the device and it worked
I tryed soft resetting the device and it worked
But the biggest surprise of all is that after using the new cable, also the old one started working ..
i guess there must have been a software bug that has gone (hope forever) away.
For those interested, the new cable is a double one: one side is usb, other two sides are charge connector and hotsync connector.

have you got a web link for this one you now have?
friend of mine has apparently got a tytn, I'll pick up a 1.2A USB / Car adapter this weekend and see what happens, hopefully the extra .2A should enable the tytn / exec to charge normally in a car.
Having had an exec for a while I will agree that most 12v/USB adapters struggle with the exec, but hopefully this will make the difference, if it works I will post the details of the company selling them (they are listed for the PSP)
I haven't had this trouble. Just got my new MDA Vario II and I've used it with my old MDA compact mains charger and the car USB charger and it works with no problems.
Tried it with the Vario II on and off and have a charging light on both.
I purchased a new vent holder with a car charger, and it charges the phone up OK when it is off, but if it is on it says charging but does not actually charge. This is especially annoying with Satnav and after an hour or two the phone dies and I don't know where I am going!
Anyone know what causes this? I guess it can't provide enough power for the device, especially when using the internal GPS, but I think it doesn't even keep up with the device is just turned on.
I am getting another charger just in case, but never had the problem on my old Touch....
..
try -> start/settings/system tab/power/battery tab - uncheck the box "when the device is turned on...."
It isn't ticked...
..
try ticking it..
That will have the opposite effect, it charges fine when plugged into the wall, the problem is something to do with the car.
Does anyone use satnav on a touch HD and have it charge at the same time?
Well there could be one or two issues.
On the USB port there are four connections, a positive and a negative and two data pins. When you plug your Touch HD into a PC power is supplied down the power pins and after negotiating with the USB controller chip over the two data pins the phone will pull up-to 500mA from the power supply to run and charge the phone. This is so the USB port on the PC is not damaged by the phone overloading the power supply to the port.
Without the negotiation with the USB controller chip the device will only charge at 100mA.
But 500mA is not enough to charge the phone with everything running, you will need at least 1000mA to do that (1 Ampere). So that is what your wall charger pushes out. But how does the phone know it can charge at a higher rate? Well inside the charger the data pins on the USB connector are wired in a way that the phone 'sees' that a higher current is available, and pulls a higher charging current.
So what you need is a minimum current 1 Amp car charger. If you already have a 1 Amp then the chances are that is does not have the data pins connected properly and the phone will not draw the higher current, meaning it will only charge at 100mA.
Thanks, I am going to try another one and see if that helps, perhaps it is just faulty, otherwise I will check if it is 1Amp.
Cheers.
I contacted the seller and they sent me a new one, which works. So it turns it my charger was just faulty.
What's the rating of the new one? and where did you get it from. I bought a 2amp (supposedly) but it doesn't give me more than 500mA.
I've had this problem and it sucks! As I'm always out on the road. But I have found a few solutions. I purchased a mini usb charger from asda for £6. After adjusting the backlight to medium this charger seems to keep the power level the same as it was before you plugged it in, so It doesn't let the battery go flat. I've now learnt to keep a spare charged battery in the car just in case it fails.
Hi Guys,
I noticed that when I connect the universal connector to my pc or wall outlet, there is noise coming from the speakers. It's kind of a squeaky sound. Anyone else notice this?
Thanks.
Are you using the same outlet the PC is connected to? Try an outlet in another room.
Its a different outlet. The tablet is super quiet when not connected. Anyone have one they can test out .. it kinda sounds like a harddrive running but i never hear the sound when actually using the device
Just a guess.. maybe your charger is rated too low amps, or going bad. I have used 3rd party chargers that were cheap and caused the tablet to make a noise. But, with a good charger it stops.
Try substituting another (known good) charger and see if it still makes noises.
Good luck.
Whoops. I meant the universal connector port. The charger is the original asus prime one. All hardware and charger is original. No third party stuff.
Hey all,
I am thinking about getting the official Samsung car dock but had a few questions before I bought it:
1) In my youth, I heard that plugging and unplugging a device shortened the battery life. I am afraid that would be the case when I would charge my phone on the way home from work, when it's only like 40% still. Do these new batteries still have the shortened battery life problem when the charge cycle does not get complete? The same question applies to an alarm clock with phone dock that I am thinking about purchasing (know any good ones?).
2) I have a custom stereo with a USB input. Would it just work to go straight from the mini-USB to the stereo USB, and not need to use both the AUX output from the dock as well as the cigarette lighter? I guess using the AUX option I could bypass the issue in #1 above, since AUX doesn't charge it (mini-USB to USB does charge the phone), but I still prefer mini-USB to USB for audio quality.
3) This is a general question. My car originally had a two-din stereo, and I bought a 1-din with a compartment for the other din. Has anyone seen something that could go in the din to help hold the dock?
Thanks for any help!
The car dock sticks to your windshield or it comes with a plastic dics that you can permanently stick to the dashboard.
The dock comes with a cigarette/micro usb cord the connects to the dock. And for audio unless your stereo has bluetooth audio you will need to use a auxiliary 3.5m jack from phone to car.. That's how I have it set up on my car

The car dock will not allow a USB connection to the USB port - it is changed to an analog audio output when docked.
As to 1) - That's an old rule from the days of ****ty timed chargers that would start charging a battery for a set period of time when you turned it on. No phone sold on the market today is set up like this - they all have intelligent battery charging circuits that can handle almost any plugging/unplugging pattern.
