Hi

When using GPS on my HOX while charging at car, the phone usually drain more battery then the charge speed, meaning i see msg of less then 30% if i want to exit.
then i searched online and i found that if the Phone find the car charger it usually change charging to 500ma and not the 1000ma usually.

1. How can i check the charging Amp ? i wont to test few of my car chargers.
2. Can anyone recommend of good AC like car charger ?
i found some Kinsington and Griffin 2.1A ones, but i'm quite sure its for iPad and still be recognized as DC (0.5A)

I have to original one, and its 5v/1A

but i still read that DC identified charger gives 500ma instead of 1A in the AC one.

Many chargers designed for iOS devices will only charge non-Apple devices at 500mA even if the charger is rated at 1A. The Battery Status will read "Charging (USB)" instead of "Charging (AC)". You can often fix this by shorting the middle two USB leads in the charger (in Type A connectors, these are the data lines). Or you can get a charge-only cable which essentially does the same thing:

The problem you are having is that most OEM car charger manufacturers don’t appreciate how our smartphones work, and they neglect to short the two data pins out in your charger.

When you plug your official HTC wall charger in, the phone detects that the two unnecessary data pins are shorted out (as obviously HTC know to do this) and the phone will not limit it’s own charge to 500mA.

Use an unofficial charger, and the phone see no short on the data pins and so assumes it’s plugged into a PC/laptop USB port, and will restrict it’s own charging to 500mA to prevent damage to a motherboard.

Your car charger may very well be capable of dishing out 1A, but they manufacturers just didn’t appreciate what they need to do to tell your phone to start taking it.

I have had this trouble before, and there are a couple of options.

1) Only use official HTC car charger.
2) Take a spare charging cable, and carefully peel back the insulation. Then carefully cut back the screen. You’ll find 4 wires. Red, black, green & white. It is the green and white that are data. Cut these. The end of the cable that plugs into the phone, twist the white and green cables together. Insulate with electrical tape. Tape the cable back up. NEVER USE THIS CABLE WITH A PC/LAPTOP. But you should now find you charge at AC.

Been using a modified cable in my car charger for years, including with this HOX with no problems.

Check the "battery use" under settings>power.

While charging, it will say "Charging (USB)" or "Charging (AC)". If it is charging (AC), then your cable is ok, just make sure your charger's output rating is 5V x 1A.

Also, note that if your in a hot country, and your phone is under the windsheild, under sunlight, the phone would heat up & not charge (light will flash red).

Yes. The data pins are the two center ones I think. Should be obvious add they wont be connected to anything else in the charger. Good luck!

I did this with my Griffin charger, was pretty easy to disassemble and solder the two middle pins together, now shows as charging AC.

Just purchased a PowerJolt on Amazon and noticed there were a few user-uploaded photos showing which pins soldered together. You are correct, it's the two center pins.

Interestingly, one buyer noted that their pins were already soldered together from the factory.

I think there's a bit more to it than simply shorting the data wires.

I'd try the official hox cable in the charger before messing with wires. For some reason 3rd party cables show as ac for me but the power level is severely reduced compared to the official.

Has anyone tried the HTC CC C100 or CC C200?

Bought the eBay car charger that was recommended earlier, but still get USB charging with it in my 05 Focus + the HTC charging cable
- Could my car the problem????

Anyway was looking at either the Griffin PowerJolt that was also recommended earlier or the official car charger
- Just want to make sure I get AC charging when using GPS!

I've got the c200 and it works at full ac speed as long as I use an official htc cable with it.

Bought CC C200 from Amazon (£4.69 from 3rd party seller, but fulfilled by Amazon)

Does give AC charging =)

Need to do some more testing, as I get AC charging using the "curly" HTC cable I got with the CC C200, with one of the other USB car chargers I have + want to double check that phone doesn't drain, using GPS even with AC charging

=)

From the testing done so far, even with AC charging - it doesn't provide enough power to run GPS (CoPilot), without losing charge & was running Core Control - using 2 cores

Going to test another car to start ruling things out =(

I use CoPilot (v8) quite a bit, mine manages to hold charge and stay topped up.
I think being in (not very sunny UK) helps as if the One X is in direct sunlight it will warm up, add charging and use and you have a recipe for heat.

Maybe try directing an AC vent on to your handset.

Install something like Battery Monitor and check how fast it is charging (when battery is < 80% full).
If it is < 500mah it's your charger.

I am using a Brodit holder and my One X charges when using Sygic, on full brightness and no tweaks.

Battery Monitor Widget Pro installed - monitoring seems funny, as it seems to update every few minutes, rather than "real-time"

Managed to get 1 charger / cable combination to charge AC and only just provide less power than needed (i.e. battery still went down, but a lot slower than other combos)

Still testing, but appreciate all the suggestions! Thanks!

    its not AC or DC that effects the current output of the device

    you simply need to find a car charger with a 5 watt (5 volt @ 1 amp) output

    like this:

    http://www.amazon.co.uk/Griffin-GC2...W6/ref=sr_1_12?ie=UTF8&qid=1338119269&sr=8-12

    note the iphone compatibility is simply because they include an ipod cable, use the HOX cable and you'll be fine
