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.

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:

Hi
I'm having a problem with charging my HTC devices on my Honda Fireblade.
My motorcycle dealer added a cigaretlighter so I can charge the HTC while driving and using it as GPS.
The problem is that the Sensation (and even my Desire HD or HD2) won't charge although the indicator light on the charger is on. So I've tested the charger with other equiment and it works.
Does anyone knows what can be the problem? The battery of the Honda is 12V
thx for any advise!
What is the charger output?
It should have 5V and 1A or 2A. If voltage lower, it will not charge..

I use this charger also in the car and there it works.
I bought this charger when I was on a trip and it's original for nokia
He's right, your charger probably doesn't have enough output. I noticed that certain house chargers I already had were charging the phone extremely slow and others charged the phone quickly. That's when I noticed that the ones that charged the phone quickly were 5v and had at least 1A. The ones that were less were too low of an output to charge the phone properly. You're more than likely experiencing the same thing. I'm willing to bet if you check what the output is on the charger you're using you'll probably see it either isn't the right voltage or the amps are too low...or both.

All right, I'll check it first....it's in the car now
The nokia charger is
input 12 V
output 5V - 550mA
So you guys are right....it still doesn't explain to me why the charger works in car and not on motorcycle. Maybe because the battery output in car is higher A?
I'm not into electrical stuff :-(
So, if I order for example this one....it could work on my motorbike?

Bear in mind I'm just speculating with this but your car's cigarette lighter may be putting out more power than your motorcycle's (especially since it wasn't original). Also though it may have been charging in your car, that doesn't mean it was charging at the rate it should have been (it might have been barely charging). Sort of like what I was saying I had experienced when I used a lower output charger (the really slow charging).
Yeah that looks ok. I'd imagine that you be sufficient.
The charger I have is a Nokia DC-4. Bought from Nokia themselves as lots of shops sell copies. The copies don't seem to have the right electronics in them to power the more expensive (read: power hungry) phones. I have to have a converter on the end to go to micro-usb (also a Nokia part) but it means we can also use it for the wife's Nokia.
I'd make sure you went genuine part, or at least one that someone else says works.

It should be working. But better you try it first, borrow from a friend that have this charger and try it on your motobike. If still not working. My conclusion is that your motobike most probabily produce a low voltage or current than what it were suppose to.

I've received the charger. Did a test last night and test....failed. Still not charging.
So :
could it ba the usb cable itself?
can I measure the output current on my bike?
I'm with stupid on these matters, and my mecancic is on holiday
Guys can someone tell me a good charger for my i9000. My original charger was bricked and now im using chines charger but it get lot of time to charge...
If someone help me i definitely HIT THANKS....
Buy an original charger.

You just need one with a higher output current. I forgot what current the OEM one has, but you want one that has an equal or higher current output. Don't worry about overcharging your phone. It has a chip that limits the maximum current it can receive.
Hello,
the caracteristic of original are: 5V - 0.7A
But some china's power supply marked 1A rely deliver less...
If you can buy an original!

Is this true? im afraid of charging my phone with 500mA charger?
So can i charge it with 500mA?

Yeah, if you buy a no-name Chinese USB supply then you either get your phone plugged straight into the mains or the circuits and components of nightmares.

As far as safety, current doesn't matter. At 500mA you'll be charging pretty slowly though.
i use 2A charger from TomTom and working fine even with working GPS navigation and still can charge to 100%.
Hi , I have lg g3 with it's own charger ....
1.8 A , if I charge it with another one 2.1A .....can it be harmful for device ?
Iam waiting ?

it shouldn't harm the devices, and it will make it charge faster.
although the higher amperage might wear out your battery a little bit more
Heat is what damages the battery, not higher current. Of course, higher current to the battery means it'll get warmer. Just make sure it doesn't get too hot.
Thanks to replyies , my wonder about. Some thing I heard before "high current than the stock charger can harm the charging IC "did that real ??

It's the device drawing power from the charger, not the other way round. If the charger's rated for a higher max amperage (and same voltage), it's not an issue.
The phone will charge at the same speed if a proper cable is used.
Hi
I really have no idea how much 0.1A is, so this might be a very dumb question, but here we go.
I know the phone is capable of 2A charging with the charger there is with it, but will it hurt the phone using more or less A? The volt is still 5V tho.
Because I have a powerbank, that is 1A and 2.1A in second USB port, so is it safe to use both? (If yes, I would of course use port 2, for faster charging).
Also, is this true for any (newer) devices? I mean, can I plug any newer device into any Amp and just enjoy faster (or slower) charging or do I need to use the Amp that was with the original charger?
Thanks in advance
The phone will regulate it, 2.1amp won't hurt it. I have a power bank that does 2.1 and use it all the time. You likely won't find a charger that will put out much more than that tho. Even for tablets with much larger batteries.
You're fine...
A stands for amps which is a measurement of current. Just FYI.
