Accessories Car chargers

An important fact about charging is: Only the phone decides how much current it'll use for charging.
The charger's spec just tells how much output current amperes the charger is able to provide to a phone.
So the phone won't get any harm with a 4A charger :)

The phone's info tells about its charging state (Settings, About phone, Battery, Battery status ...):

"Charging (AC)"
is showing when phone is charging on the wall charger which came with the phone.
It means fast, high current charging with up to 1000mA (1A).

"Charging (USB)"
is showing when the phone is charging on a PC's USB plug.
It means slow, trickle current charging with up to 500mA.

Navigation apps are draining the phone's battery much more than other apps.
Nav apps drains more current than an "USB" charging can provide and the battery's level is going low despite the charging.
So when you are using a nav app in a car you'll need this "AC" charging with the car charger for charging properly the phone's battery.

Most phones will detect if they can use "AC" charging at the instant when they are put to the charger. They'll detect this when the charger's connector has an indication.
And most phone manufacturers do code the microUSB connector of their wall chargers and car chargers with that indication.

But most manufacturer of generic chargers don't code their charger's microUSB connector in this way because they want to be compatible with all kind of USB devices.

So to be sure you should buy an original HTC car charger (C300) for your Desire HD :)

Thanks for the reply, I knew most of what you said just wanted to make sure there was no problem with using the higher capacity charger.

Unfortunately i can't use the HTC genuine charger as it doesn't fit properly in Golf mk6. I was going to buy one but there is a very detailed review on amazon by someone who elaborates the problems with the HTC in that car.

HTC CC C300 Dual USB Car Charger with microUSB Cable
I bought this for my HTC Desire HD, TomTom, and iPhone 3GS which is why I went for the dual usb charger.

My intention was to use this charger in my VW Golf mark 6 to charge my tomtom satnav and iphone while I work (I work in multiple locations so travel alot) and to charge my HTC Desire HD while not at work.

I hit a problem pretty much straight away, the charger head fits into the socket ok but it doesn't fit in perfectly which means the unit can move about, and while it is moving about the charge light goes on and off. So while the unit functions just fine, I think it may just be that it isn't 100% compatible with the socket in my VW Golf mark 6. I have therefore returned this to Amazon.

Other than this, the device has two usb slots which is capable of charging your HTC Desire HD whilst using it as a satnav. Watch out for sub standard chargers that can charge your phone alright, but not whilst using it as a satnav due to low power output. This charger supplies 5V @ 1amps on both usb slots so it is perfect for those of you who wish to use the HTC Desire HD as a satnav.

The micro usb cable that comes with this is for charging only, it cannot be used for data sync. Some people have said that the cable is a little short but it seemed fine to me and I keep my devices on the right side of the windscreen while the socket is near the gear stick.

Overall, the build quality is good but I would not recommend this to anyone who has a VW Golf mark 6.

I see, some Europeen cars seems to have problems to meet the mechanical standard for the zigarette lighter ;)
Yes, I remember that I saw some posts about in German forums.

So I hope that this Proporta 4A car charger will charge your DHD properly with 1000mA.
It would be nice when you would review about in the forum :)

But if the Proporta won't charge properly there is an option:
It is this HTC "charge-only" USB cable, mentioned in this Amazon review.
I have this curled cable which came with the HTC car charger C200.
So I know the cable has this "AC" coding in its microUSB connector.
I use this cable with a generic 1.2A car charger and it charges all my HTC phones properly with "Charging (AC)" :)

I am looking for a car charger that does 2 USB and also a cigarette lighter pass through for a TomTom etc

My current cigarette charger can't power the phone enough for it to use SatNav on the move, so I get a dead battery when I get to my desitination

Didn't used to be like that though, only happened in the last couple of months
 
I just got a usb charger sorta thing from ebay.

Plugs into the 12v socket, allows any usb plug to go in.

Gives out 1A

I use a genuine Nokia charger which I've hardwired into the car behind the dash. I *think* it's 800mA output which is enough to have SatNav and an MP3 player running and charge the phone. The DC-4. I got it from Nokia direct as the previous "pattern" ones I'd bought weren't up to the job (charging the E71). Nokia do a round-pin to micro-usb convertor cable as well.

NB: I should get around to changing it now as both my wife and I have HTC phones (micro-USB plugs) but it works and I can't be ar5ed to take the dash apart to fix something that ain't broke ....
