    Just looking at getting a new dual USB car charger as the old one from maplin is only 500mA per usb socket. I notice that there are some that are dual 1amp or others where 1 usb is 2.1 amp and the other 1 amp. Even a proporta that is dual 2 amps per usb.

    Is there a problem using one with a 2.1 amp output as opposed to 1 amp?

    This one seems ok

    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.

    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 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 ....
