Has anybody already found a charger for in the car, which is recognised by the phone as an AC charger? (besides from the official HTC car dock/charger)
Because the charger I'm using is recognised as an USB charger, and therefore doesn't charge faster then 500mA.

What chargers are you using?
And it's not a big problem, it's not even a problem, it's just how the charger/phone works..

having it recognize that it is AC vs USB is one problem... but even if it says it is charging via AC, it doesn't always pull more than 500ma (even if it is a 2.1a charger, etc). i've been testing chargers and inverters w/ac adapters all week. i've got one more to test before i narrow down the issue (hopefully).
this was just delivered: http://www.amazon.com/gp/product/B009TBF7IG/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1
tested it using my normal method-- watching Battery Monitor Widget for about 20 minutes, while running Ingress. the app reported battery draw fluxuated between -56 and +300. i've been using Ingress as my test app because it tends to really hammer my battery. this new charger doesn't seem to be as consistent as the 5Vdc/2A wall charger i use with an inverter, but i'm going to keep trying it to see how it works in 'real world' cases over about an hour or two. i'll let you know, but this charger is potentially an answer to this car charger issue.

Ok that looks promising indeed. Does the phone recognise it as an ac charger?
Too bad I can't order from amazon.com and on amazon.co.uk it's not offered.

Yes, it is recognized as AC-- but so are most of the car adapters I've tried (mostly, those just have the 2 middle pins on the USB port shorted), but they have a lower wattage output, typically at like 6-8W. I bought this one specifically because it says it can output 5Vdc/2A, or 10W, per USB port. I suspect it will dip below 10W when both ports try to output at max capacity, but I'll be able to test that this weekend (and aside from testing, there's virtually no time where I'd have a need of that).
I performed a second test, about 30 minutes of talking on my phone via a bluetooth headset, Ingress open and running, push emails for GMail and Exchange, full brightness and volume, etc, and it only dropped down to discharging a handful of times. This is definitely much closer to the results I've gotten when testing a 5Vdc/2A output DC adapter.
You might be able to find other 5Vdc/2A adapters on Amazon UK, and ruling out the 'piece of junk' factor, hopefully some of them will work. I'd think that for the duds, you can at least return them for a refund by stating they don't output the proper wattage as stated on their product pages.

I seem to have very slow charging times in the car. I'd like a quality car charger that has safe but fast charging times. I know some of the 2.1 A ones only work for iphones and ipads. Any recommendations? I'd prefer one that has a usb port so I can plug in a straight cable or one that comes with a straight cables. The coiled ones don't work well for my needs.

I Have two of these and a whole mess of these. When a cable goes bad from being mistreated, I grab another from the glovebox and stick it in the USB slot. If you have an older device that uses mini usb (slacker G2 for instance), you can just switch out the cable. After searching around, this one seems like it would push out more charging power, though. The Belkin one doesn't have a rating and the Kensington one pushes out 2.1 amps. I think I am going to upgrade.
It's all good. I maybe we can get this moved.
Samsung Galaxy S II
You need a charger that can put out more than 700 mA and shorts the D+ and D- lines of the USB port together.
If they aren't shorted together, the phone will go into USB charger mode, which will limit current to 450 mA if you have the same charging chip as the I9100, and 400 mA if you have the same charging chip as the I777 on AT&T.
Stock current limits on the I9100 and I777 are both 650 mA.
On the I9100, the current limits can be tweaked with some kernel mods. On the 777, they are fixed in hardware. Unknown about the Sprint variant.

Hey Everyone,
Thought I would start a car charger thread.
I picked up one of these at Walmart the other day:
http://store.griffintechnology.com/smartphone/powerjolt-dual-universal-micro
And it works quite wonderfully. It's tiny, and even with bluetooth/GPS/Navigation running, it was slowly charging the battery. And it charges it quite quick if you don't have nav running.
It can be a bit annoying to pull out once stuck in, although you probably don't need to do that very often.

it used to work perfectly on my HTC Desire HD (with GPS+Bluetooth+WIFI ON )
any recommendation on how to fix this please ? like a reference output current that is enough to charge the GN while navigating ?

The Griffen claims 1A per USB port, and I believe it.
Online reviews say some users with other phones need to mod the Griffen to charge their phone, otherwise it only supplies 100mA. Some crack open/mod the Griffen to short two terminals to get the full charging ability, and/or use a 'charging cable' which shorts the terminals within the cable.
As a reminder, the Griffen seems to charge the Note full blast, but perhaps something similar is needed for the Jabra. I suggest installing 'Currentwidget' to see what sort of charge you are getting.

I have battery monitor widget installed & it shows charging via usb when i connect it to jabra charger, but the weird thing is that the galaxy note starts mtp mode once i connect it!

I just bought this dual port 2.1A + 1A charger on eBay for £2.49 inclusive and delivered the following day....
http://www.ebay.co.uk/itm/2-1A-Dual...neChargers&hash=item19ca66b4df#ht_2865wt_1163
At first it seemed the phone was only drawing a "USB" level of current, so I was all set to rip it apart and solder the centre pins to force AC charging, but when I double checked with a dry run and a temporary short the phone switched to AC charging. Now it seems to be continuing to draw "AC" levels, so maybe I had a poor contact initially and a few (un)plugging operations have made the contacts more reliable. I'll try it out later today with satnav running and see if it keeps up with the pace and report back.
EDIT : Charge level draining like water out of a sieve with this thing whilst running satnav, and the phone said it was "AC" charging too. Switching ports didn't help.
i'm using the official car charger from my old nexus, the only charger i found can charge my phone with 3g and nav on because of the 2A output. other cheap usb chargers i tried with so called 2A output just don't work

Do you have to use the white charger that comes with it or can I use my old desire hd black rounded one. I'm just thinkng that the voltage or ampage or whatever it is may be different. Looking to keep a charger in the office you see. Also does it make a difference in terms of battery life and general goodness for the phone if you charge connected to your pc. Much obliged

No you'll be fine with both. Both will state their outputs on them, and both will be 5VDC at 1A. Generally any charger with a micro usb plug on the end will be charging at 5v. Charging current capacities vary. My wife's blackberry charger also works, but only has 600mA output current so charging the phone could take 40% longer. I've been using my desire charger on my onex.
The main reason to keep with HTC chargers, is that the cheap ebay Hong Kong stuff generally have cheap AC/DC converters in them, and are poorly regulated. This can cause a number if problems witha smart phone, such as heating and damaging the battery, and touch screen interference.
Charging froma PC USB output limits the charging to 500mA, so obviously will take twice as long as your HTC wall charger to get a full charge.

Well, I am in the situation now that somehow the One X will not accept the Motorola Atrix (US) charger (I am in Singapore, but chargers "convert" automatically in my experience). It works fine though when plugged into the PC, but obviously will take a very long time to charge that way.
*edit*
It worked with the Moto charger once the battery charge was up to about 20%. When it was 2%, phone would only accept USB (or, potentially, the original HTC charger which I did not have at that moment).
Hi, i'm a heavy user some days, so I need a compact charger I can put on my keyring. I thought I had the perfect one of eBay for ~$3 (http://www.ebay.com.au/itm/200720521235?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649)
However, after several tests using "Charger Timer" I figured out that it only chargers at 500ma-thus making it take a very long time to charge. The point in this charger is to provide me with a quick battery boost ad-hoc, but it's pointless as it takes 1hr20 for a full charger(stock at 1000ma takes 40 minutes)
The seller offered me a replacement, but I'm not sure whether to take it incase I wait weeks then find out its the same low-output charger.
This is a popular charger (dx, eBay)-does anyone else own it? Does it work for you at 1.0a?
Can anyone suggest a cheap alternative compact charger?

i dont know if this would work for you or not, but I just ordered the Anker Astro Slim 3 and it has two ports that will charge at 1 Amp each. It is slim enough that i have been able to charge my Galaxy S3 while using the phone and stacking the charger directly behind it. So far, i am very pleased with it. I am attaching a couple of pictures so that you can see it. I am charging my nexus 10 and my nexus S in the picture. Hope this is helpful
Thanks for that!
But I'm after something much more compact.
I'm really surprised this isn't a common thing-having it on my keyring (even if 0.5a) has been incredibly handy.
Any other suggestions?

I've finally received the one I ordered, and no surprise, despite being advertised as 1a, it charges slooowly at 0.5a.
Size of it was prefect- fit nicely on my keyring and wasn't even bulky
And then after a week, it broke...
I like Anker stuff as well since I reviewed a lot of their products (in my signature link). The problem is that it sound like you are not from US, Australia from your ebay link? That is always an issue because a lot of US companies deal only with a few international amazon. You mentioned DX.com - love their products as well, reviewed a lot of their stuff, always a pleasure to deal with, and they ship to Australia without a problem.
Here is my thought about your 500mA charging. Are you sure its not a cable? Most of today's chargers are 1A-2A (all new Galaxy stuff charges at fast 2A speed) while tablets like Nexus 7 use at least 1A. So it's easy to get 1A charging speed out of most of today's chargers since they all use a common voltage/current regulator chips inside. BUT, you will LIMIT your current with usb cable. A lot of these cheap cables are designed for computers, and a common USB2.0 PC port only outputs 500mA, and cables are made out of thin wire. Thin wire will limit your current, will overheat, and will create other problems. For 2A you need to use USB cable with a thicker wires. So just look around your house for different usb cables to confirm. Usually the OEM cable that comes with your phone will be designed for max charging speed of your phone. I like buying Monoprice cables, but again not sure if they ship overseas.
At DX, look for the HTC One chargers. After lots of frustrating purchases those were the only that I could find that delivered the mentioned current.
I think you may have trouble finding one that fits your country's wall socket.
Have you tried different cables? My S3 draws anything between 0.3 and 1A from my charger depending on the cable I use.

No to anything with the name Samsung. The LG Optimus G Pro E980 charger plug I have is 5v 1.8amp. Get any correct USB cable and make sure the plug is at least 1.8amp, a 2amp plug will also work. I have trouble with generic car chargers that are only 1amp, they keep my phone alive but take hours to charge it and it will eventually burn up the USB cable but not harm the phone. Trial and error results.:good:

Look for a used iPad charger in your local market. It can be for the iPad 1st gen even. I've never used off-market chargers with expensive gadgets, a couple of my friends' phones were fried that way.
I have noticed, keep in mind I just got this phone so still learning it, when my battery wasn't fully charged the LED on the home button wasn't working quite right. It was working but very dim. Now that the battery is fully charged the LED is nice and bright and not dimming on me. Is this normal? A power saving feature maybe? Or could there be something wrong with the LED board underneath?
And most Ipad chargers are putting out [email protected] amps. Isn't that a bit too much?
