charge exec with an ipod charger?

I have a mini usb lead with me but not the exec charger. Can I just plug this into an IPOD or Blackberry charger and will this charge it?

I think you can without problem...
However, there is a small issue:
The usb standard specifies a maximum 500mA current for the usb supply (over 5V), but to charge the Universal in a reasonable amount of time more is necessary (The supplied one is 1A)
I succesfully charged the battery using a motorola psu, and in the same way you can charge it leaving it attached to the PC usb port.
I am pretty sure there is no risk for the phone but it is possible to overload the power supply - you better check it does not run too hot. Also, put the phone in flight mode and turn it off, to minimize the amount of total power used

Not sure which ipod charger you talking about, personally i use the original one from apple (white with the USB plug) and it wks fine. The original charger for universal also has the same current rating of 1A @ 5V so I guess it shouldn't overload it.

Yes, I charge my Universal with a BlackBerry charger from time-to-time.
Keep in mind what TheDayOfCondor said about the original charger putting out 1 amp while the BlackBerry charger is only rated for 0.5 although I haven't had any issues.

right, that's good to know. thanks.

Any software that will show power input when charging?

Via mains and car charger?
My Vario II doesn't seem to be charging in the car, even though the charging icon appears.
Thanks.

Are you using an approved charger. Many phones using the same mini USB connection actually use half the current of the Hermes when charging. So it is conceivable you are delivering charge but at a low mA and consequently looooong charge time. Indeed if the circuit in the Hermes is more sofisticated it may in fact be delivering 0mA to the battery.
There is also a known issue when using car chargers that if the connection is interupted in anyway when connected then it will only charge when the Hermes is off. This can only be re-set by doing a soft reset, after which it will charge when on or off.

Also be aware of cheap mini-usb chargers.. A while back there were some people that fried their wizards with cheap car chargers bought off ebay.
I use a belkin mini-usb charger that i purchased for my magician way back in the day and its been working for my wizard and hermes.. but it didn't charge my sda.
Also i think batti will give you stats on what your looking for.

I AM using the charger that I used to use on my SPV C500, but I could sworn it used to charge my Vario II fine. Now, however, it seems to drain the battery if anything.
What's a good car charger for the Hermes then? The official HTC Tytn is £18 inc postage at Expansys. Any cheaper?
Cheers.
P.S. Installed Batti, and while charging from mains it says 4.197V. I thought power output was done in Amps?

Yes voltage without power rating is a bit useless, you're right you need the amp reading.
I cannot advise about car chargers as I use a 12v to mains inverter so I always use mains chargers for my laptop and phones / PDAs it's a lot simpler and I have it permanently wired in with a mains socket in the car.
Mike

P.S. I note that both my SPV C500 (Typhoon) and Vario II (Hermes) were supplied with mains chargers from HTC that put out 5V/1A.
Does this not suggest that both phones have the same charging requirements?
Thanks.

try battery status
there is a link in the hermes wiki for battery status.
i find this a useful tool.
it will show power drain and charge in miliamps.
always fun to see the power drain spike up to over 1000 mA

Thanks CrunchyGremlin.
I have installed BatteryStatus as mention here http://wiki.xda-developers.com/index.php?pagename=Must_have_tools
It shows the mA drain (or + when charging).
Cheers. I'll run this next time I plug my car charger in.

Help on charging issues

Hello,
I have been trying several charging methods. I currently have a 4800mAh battery and 02 x 1620mAh batteries for backup in case the power runs out.
But when I am out travelling I need emergency or alternative charging methods other than leaving my laptop on.
I have tried Wall USB chargers but none of them seem to be able to make the charging LED come on...
Things I tried :
1) 500mAh output Wall to USB Charger
2) 1000mAh output Wall to USB Charger
3) 1000mAh output Solar (1350mAh) Battery
4) 850mAh output Car Charger
5) 1500mAh output 04 x 2500mAh AA battery portable chargers
None seems to work... And when i am driving the batteries drain quite fast when I am run GPS...
All will work when I suspend my unit, but if the unit is on, it will not charge. And it can't be off to charge when I have the GPS is running.
Any advise?
Thanks

Charging batteries simultaneously / at the same time

Okay. So I want to buy a minimum of one 1600 mah extended battery (in addition to the O.E.M. battery which came with it) for my Tilt, but I need a way to charge it at the same time as the other battery that will be installed in my Tilt. I have seen at least a couple of third-party cradles / docks (they struck me as cheap / poorly made) that do have a charging slot for said additional battery in addition to the connector for the bottom of the tilt, so yes they will both charge at the same time. Here's the problem: I bought seidio's slim rubberized case for my tilt, & I'm unaware of any other cradle / dock that will fit the Tilt with that case on it besides the InnoDock cradles that are on their website, & those do not have a charging slot for an additional battery.
So, do any of you guys know how I can charge an additional battery?
Are you guys aware of any other options available to me besides purchasing one of those cheap-looking third-party docks / cradles with the charging slot for an additional battery?
That would mean I would have a dual dock / cradle charging solution.
I hope there are other options.
Thanks in advance for your help, guys.

Emergency charger and Tytn II

Hello, I've just bought an emergency charger for my Kaiser. It takes the power from an AA battery and gives the USB voltage in the output. It works great with my Mio A 501, but doesn't work at all with the Kaiser. I did a quick search and found this in a discussion about car chargers:
Are you using the HTC charger or an OEM one?
The HTC charger works all the time the OEM ones don't - the reason being that if you use a normal Mini USB cable, the handsets will only take a charge if there is an indication of a data connection (either than gprs or the cable) - otherwise it won't take a charge.
You can apparently solder a couple of wires together on a normal mini USB cable - but I wouldn't know where to start on that!

Now I've already heard of that, for example, a Play Station Portable needs the data wires in the USB grounded in order to charge. Is it the same with Kaiser? (putting three wires together isn't a big deal) Or is there an easier way how to make it charge?

So, I gave it a try and soldered the data wires with the ground wire. But when I try to charge the Kaiser, a yellow led starts to glow (which it didn't with the original cable) and, after a minute or two, the led goes off and Kaiser stops charging. When I turn the Kaiser off and then plug the cable in, the yellow led doesn't go off. However, when I turn Kaiser back on to check the battery meter (after about half an hour), I find out that the battery didn't take any charge at all. So, could anyone tell me what the problem is?
thanks, Mike
PS.: Adding some photos of the wires...

Probably because of the voltage...
Hey!
Have you checked the output voltage of this charger? Standard charger outputs 5V. If yours outputs less - the battery won't charge; if outputs more - you may "burn" your PDA chipsets
5V - 5.5V is safe range.

I found this on thinkgeek.
http://www.thinkgeek.com/gadgets/cellphone/b43f/
It says for iPhone, but sure it would work just fine with other devices that have issues.

had a same problem but using it in the car...
when i got my tytn2 i immediately bought a car charger and the salesman told it's an original one, said output 5v 1A.. when using in the car it charged for a minute or two and went off... than i got from ebay a micro usb 1A charger (used for iPhone too) and tried in the car-> it work flawlessly
