Gembird Car Charger

Hi!
Has anybody tried Gembird universal charger with Diamond ?
http://www.gmb-online.nl/eGMB/item_view.aspx?id=3315
Is the current of 500 mA enough for Diamond ?

i think you will find the output current too low to actually charge the Diamond.
The official HTC Car Charger has 2A output, the one you are looking at is 500mA...

Thank you!
That is what I thought, the current is too low...

i have charger to my car with output 5.4v.
in the diamond book it is 5v.
both of them is 1A.
can i use it?

500mA wont charge the Diamond -it wont even light it up!
Not very funny when you find that the 500mA car charger you used for years with no problem on other phones, wont charge your Diamond, and you end up lost, with no GPS and no phone - just a dead battery in the middle of the bloody countryside at night.
Take my word for it

500mAh will charge your phone, but under heavy use you may not get much of a charge. Your computer's usb ports will deliver up to 500mAh and will charge your phone.
I have two car chargers which output 1Ah. They work fine. I found one in the game accessories for the Nintendo DS.

Yes, you can use it. But the question is, "Should you use it?"
No, you should NOT use it. Current must be of a minimum value to work. Voltage must be a maximum to be safe.
Best not to chance burning out your phone unless you can test the charger output under load.

thank you very much.
i am going to buy new charger.

I have a 500mA car adapter and mains plug which use a USB lead and non of these will get the phone to charge.
These work perfect with lots of other phones.
I have not tested them to check if they are actually supplying 500mA current, but I see your point about a USB PC port supplying 500mA

How to charge with a higher current?

When using my Toch Diamond as a GPS which is connected to a car charger, the battery will run flat in a few hours. Is there a charger that will charge it with a higher current than 500mA? It is inconvenient for a long trip.

Wait ..... you are saying that your GPS app runs your battery down even while plugged in the car charger?
Mine doesn't do that...

Are you using an original HTC charger?
Some of the generic after-market car chargers output a lower current than what the GPS is actually draining from the phone, so effectively, rather than just charging it, that charger is simply "extending" the time it takes to drain the phone battery.
I'm not near my HTC car charger at the moment, but if I remember correctly the HTC charger outputs 2A.. ie, 2000mA? (can someone correct me if I'm wrong?) And I have no flat battery problems while using TomTom... (The fone does get warm, but that 's another issue that's been discussed previously...........)

Most car chargers only do 500mA
When using good navigation it will pull more than 500mA off your phone, so eventually, the phone will drop dead It's true, I have this too.
With an other ROM it can be fixed! Now I don't have this problem anymore. You can also connect 2 chargers parallel but you got to have the possibility in your car. Or you buy a universal USB car charger which can handle 1A. Just like home wall charger (No 2000mA ).
Good luck!

My car chager (with a mini USB output plug) is rated at 5V 2A. My suspicion is that the charge current is determined by the phone, not by the charger. The charger is simply a (constant voltage) 5V power supply. Even if the chager is capable of supplying 2A, the charging circuit in the phone is limiting it to a maximum of 500mA. If the phone is designed clever enough, it could allow a higher charging current though signaling via the two signal wires of the USB plug. Would anyone know if this is the case or not for Touch Diamond? If yes, what would be the signals for higher charge current?
Your idea about using two chargers sounds interesting. Would you be able to give us more details about how to charge one phone with two chargers? Or are you thinking of having two phone and two chargers? That is, after one phone battery gets flat, simply uses another phone.

Confused
I have got an O2 Ignito (diamond) I have done an 8 hour round trip using GPS and my battery has not drained... And i do have the original I am using the charger that came with my polaris. my batt always stays full when plugged in and gps is running maybe your charger is what is causing it to drain

Needs a 1 amp charger.

High powered USB car charger?

Hi all,
Can anyone recommend a high mAh output usb car charger? It has to be one with a detachable USB lead.
The one I have currently takes forever just to charge the device by a 1% increment. It doesn't also seem to provide enough power when for example I have sat-nav/GPS running (the device still drops in battery power).
Thanks.

dont even think....
dont even think about it.... i got a charger that does 2 amps instead of 1 amp and guess what my battery blew up!

So what's optimal/maximum amp rating that I can use?
The one I have I would say is pretty much useless when using battery hungry applications/services.
Just tried to check my existing charger but there is no rating on it.
Would I able right in saying the following:
A charger with a 1000 mAh, would charge my battery by 1000 mA in a hour?
I believe HTC official chargers have a rating of 1000 mAh too right? Mine one may well be 500 I would guess.
How quick do other peoples car charger charge their Diamonds?

A charger's specification would never indicate the mAh ( milliamp hour)rating, but would indicate the maximum current it can supply while maintaining an operating voltage (for usb its 5Volts.)
in answer to your question: yes your charger needs to supply more current when you have your Diamond operating and charging at the same time. not all chargers are made equal. some may max out by 500mA, therefore your diamond wont charge at all if its on. as far as I know, most chargers are rated to supply 2A (or 2000mA)
another thing: your diamond uses its own charging circuitry to recharge and maintain its battery. just because a charging adapter says it charges at 1000mAh, i doubt it would actually recharge your battery from 0% capacity to full% capacity in an hour(it just doesnt work that way, and if it did, then your battery could blow up).
as for my own diamond, i seems that it takes around 3-4 hours to get from 0% to full when it is off and using my stock 950mAh.
doing a little math here: 950mAh / 4 hours = ~250mA
therefor in order to recharge your battery, the charging adapter needs to supply 250mA.
but if your diamond is ON and you want to recharge then your charging adapter needs to supply 250mA AND and additional amount of current to maintain your diamonds power.
if youre still able to follow with what im saying here, you may conclude that you just have a DUD charger and you should just buy another one.
as for the other guy who said that a 2Ah charger blew his battery up. I'm a bit skeptical. I think your chargering circuit in your diamond is more likely to fry before blowing a battery up (and if a lithium battery blew up it would have taken out his entire diamond).

Yep, that all makes sense.
By chance, My battery (1800mAH) totally died last night. Put it on car charger and after almost exactly a hours worth of charging, the battery indicated 1% (!) Mind TomTom was running for about 30 minutes of that.
Ok time to buy a new higher rated charger I think. Any recommendations for one with a USB port on it?
Thanks.

i've been looking for one liek that on e-bay as well but i cannot seem to find one. having a detachable usb cord would be nice, but now that i think about it maybe i am better off finding one with a non detachable cable in the event that I dont have a usb cable around.

Yeah, I wouldn't normally mind one with an attached cord but the setup in my car is such that I already have a semi hard wired a usb from a 12v supply and have the [USB] cable hidden then have it pop out near to my car holder.

bingo

Check out Avantek. This charger works so much faster than any other charger I have. My Note goes from zero to hero in no time flat.

2A Car Charger for Desire

Hi Guys,
Saw this 2A car charger for HTC Desire, thought I'll post it here and ask everyone if this will work well with HTC Desire. I dont want to damage my new Desire by buying something that kills it.
http://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItem&item=300435508442&_trksid=p2759.l1259
Let me know your comments.
Cheers!!

Amps are not pushed to the phone from the power source,
They are pulled by the phone, from the power source.
Therefore the phone will only request what it needs, IE you cant overload it.
Voltage on the other hand will!
So to answer your question,
it will be ok.

Thanks Fon22. pardon my lack of knowledge , so what diff will a 700ma or 1000ma will have against 2A car charger ?? Any benefits ? or its better to buy a cheapo 2$ 700ma charger ?

WEll, it's best to get the charger that can deliver the most Amps. So if the phone needs it because you're using GPS and music and what have you - then the amps will be available instead of the phone consumes more battery than it gets from the charger.
So get the one with the biggest Amp spec - but still 12 volts

Thanks guys.
And If I am not wrong , It should work with HTC Desire as well (it is being advertised as being Touch HD)..
Cheers!

I know you're referring to the source (input) voltage, but just incase it confuses someone, you want the OUTPUT voltage of the charger to be 5V. Output voltage of 12V would almost certainly do damage as the stock charger and USB spec are at 5V +/- nominal tolerances.
Amps though, yes. Preferable to have something which can deliver at least 1A.

That is correct - the INPUT is 12V as per the car battery, but the OUTPUT should be no more than 5V - thank's for clearing that up

1A is enough.
It's another important thing to this.
I tried to explain the issue here:

Solar Charger

Someone knows any Solar charger that really works with HTC Desire?
I look in www.dealextreme.com but I don't know how many "Amp" need the desire.

all solar chargers i've found so far had an 80mAh ouput.
a usb charger has an 500mAh output and charges slowly around 4-6 hours? (never tried to charge it full via usb).
a wall charger has up to 1000mAh and charges the phone in 1-2 hours.
so i guess it takes the solar charger virtually forever to charge your phone once

Yeah, generally you want a charger with high output (at least 500 mA) and a high capacity (at least the same as the desire battery, which is 1400 mAh). Once you're sure about those two factors, you're safe.
I'm using the powermonkey explorer: Link
Output: 700 mA
Capacity: 2200 mAh
On a sunny day, I'm able to reach the maximum charge in one day (10-12 hours sun). Note that the output from the solar panel to the powermonkey battery is a lot lower, more like 200 mA. And a full charge should, in theory, give your phone 1 and a half charge. In reality it's more like 1 charge, which is still fine.
It might be a bit more expensive, but it actually works.

heh good point !

if you ever find a solar charger post it in this post where you've got it from would love to try this lol

Gizmodo reviewed this charger a while back. Quite tempted to buy it myself

Which would you choose

To use it effectively you need to use a solar charger with built-in battery.
E.g. I got an Energy Trends ET-3000:
http://www.energy-trends.eu/et-3000-solarladegeraet-iphone-handy.htm (maybe use google translate) 330mA solar power, 3000 mA battery, 1000 mAh can be loaded within 3 hours in direct sunlight
Can also be combined with this:

Arctic C1 mobile
I found this charger: arctic.ac/en/p/power/batteries/44/arctic-c1-mobile.html?c=2224 which I quite like, but
the question is: would the 5.5v output "fry" my HTC?
I tried a 3rd party usb power adaptor, which outputs 5.3v as opposed to the genuine HTC adaptor (5.1v) and the phone can't be used while it's charging.
Literally the phone becomes so unresponsive, that it's impossible even just to slide the keylock! The minute I put the phone back onto the genuine HTC usb adaptor, everything works fine and I can use the phone while it's charging.
So here is the second question: has anyone experienced this?

this one looks excelente,like germany tanke.

i dont think thats a good gadget. the usb charger does not load the desire complete full and the accu is really fast empty.... so i dont wanna buy such a gadget.

Could be so interesting for long travels

Looks interesting, if someone could share his experiences about it!
I would be gratefull
