USB car charger. Any hints ?

I'm looking for USB car charger for HD2 (US T-Mobile HD2) ... the one which has USB port in it where you put another USB cable. Here is what I'm looking for.

Here is the problem ... I have one car charger like 1. And it says 5V 1000mA, but it DOES NOT charge my HD2 ! LED light on charger is green, LED light on HD2 is red, HD2 "Settings->Power" says "Charging", but it does not ! I use USB cable which came with HD2 from T-Mobile. I'm able to charge from USB WALL charger with this cable fine. I also tried different USB cable - it works with WALL charger and does not work with car charger
My question is ... USB car charger for HD2 ... what specs it has to have ?
What am I doing wrong here ?

Just a guess but there is a setting which stops the phone charging when connected to a pc via usb. Maybe it thinks its connected to a pc?
Goto settings --> about phone --> battery
and make sure "when phone is on, do not charge the battery when connected to a pc" is unchecked.
If that doesnt help my second guess would be that the usb charger is dead.
Just search for "car usb adapter" on ebay, loads come up.
According to spoon charge (download from these forums) my hd2 uses a max of 900mA when charging, so 1000mA should be fine.
Hope that helps.

yeh I got one and it's fine.
I got a spare too so if u ever need one ...

Do use a USB car charger with higher current capacity (say 2000mah). avoid cheap (chines) chargers, boasting high current capabilities.

I ordered the HTC C200 because messing with the battery just because I could save a few bucks is not worth it IMHO. I cost me like 15 Euros and if anything happens to my battery I can blame HTC themselves.
btw the C200 is like the one in the first picture!

that's the original HTC C200 I'm talking about, and regarding those cheap chargers you can order from china or somewhere can damage your precious phone, it's not that pricey!

Car Charger Mod
If anyone is still wondering why their aftermarket car charger doesn't charge their HD2 properly, the two centre points on the USB socket need to be soldered together.

Now that I've been using this charger on my HD2 for a couple of days now, I thought I'd give an update - not all USB leads will charge your phone when it's running under load.
I tried a Nokia lead and while it charged the HD2 with bluetooth running, as soon as I started the GPS (tomtom) as well, the battery started to discharge.
Then I tried a Sony Ericsson mini USB lead (supplied with my X1) with a mini-USB to micro-USB converter lead from ebay, and my original HD2 lead. These charged the battery with bluetooth and GPS running together.
The Sony Ericsson X1 mini-USB lead is much thicker than the HD2 and Nokia leads.

USB vs AC charging

With my previous phone (Samsung Galaxy S2) you could make the phone think it was connected with an AC charger by shortening the two middle usb pins. This would make the phone charge with 1000mA instead of 500mA.
But somehow HTC uses a different approach. I shortened the two middle pins of my car charger, but the phone still 'knows' it's on a usb charger. So the middle pin tric is not working on the HTC One. Does anybody know how to make the phone think it's on a AC charger, and therefore being charged with 1000mA instead of 500mA?
I'm using this charger: http://www.hamaholst.nl/NL/29207/ipad-gen1-2-3-mini-autolader-5v-21a.html

IMO it is a bit silly shorting out pins. But it's your device you can do what you like.

Just to be clear, I shortened the pins of the car charger, not the pins of the phone.
This has already been done with many other phones (shortening the two data pins) but on the One it does not work, the phone still says USB charging...

-oeps-

I took an AC charger apart, and guess what, the two middle usb pins are shortened!
So what else tells the phone whether it's on an AC or USB Charger???

That charger would charge at 1amp either way. If your battery charge is high, nothing you do short of enabling Fast Charge will charge more than 500mAh even on AC. That's just how the battery works. From 0% to about 80%, it charges at 1amp, and when it touches 80%, even on an AC charger from the wall it will drop to 500mAh.

Yeah I read that. But as long as my car charger is recognised as an usb charger instead of an ac charger, it will never charge with 1A, even if the battery level is below the 80%

Sometimes it's the cable that needs changing. I've had perfectly good USB cables that would only charge at 500mAh and couldn't transfer data. The thicker ones are usually good for full 1amp charging

Tried different cables. This is not a new thing, with the galaxy S2 it was the same story. Some car chargers are just recognised as usb chargers. And when the phone detects the usb charger/computer charge is switches to the 500mAh max charge

That's true. But to be honest, I don't really need the auto mode, just need the higher mA to charge my phone while navigating
Offcourse I can also buy the official HTC CC C220 for about 10 euro's, but I would like to use my pico charger instead of a large charger... But looks like it's not gonna work out

So I guess the solution to this is that you need a USB cable that tells your phone it's an AC charger..

ANY way to charge 2012 nexus 7 wirelessly?

Do you guys know if there is any way to charge our tablet wirelessly? Is Qi charger the only way? And it's not supported for the 1st gen, am I correct?
I really hate wires...

You have to mod to add a Qi wireless charging coil or a palm touchstone coil to charge wirelessly.
Or you can buy a pogo dock and use it to charge, it's close enough to wireless.
Beamed from my Grouper

There's no such thing as wireless charging, you still need the wires (going to the desktop part of the charger) and when you use that method you don't have any choice where you put the device when it's on charge.
If you just plug a cable into the device you can plonk it down anywhere the cable will reach.

http://www.phonearena.com/news/Google-Nexus-7-hack-adds-wireless-charging-voids-warranty_id37573

The short answer is of course no. Personally, I would try to opts away from attempting any mods like this; wireless charging is still; in it's infancy and is "a generation newer" than this Nexus 7 version.

WTF!!

I can't decide if you are just trolling or if you really are clueless.
In case you're serious, learn some basic physics before you shout your mouth off.
Right now - today - the only way to 'wirelessly' charge a device is to have an induction coil in it and put it right next to another induction coil which is connected BY WIRE to the mains. So while it's handy to be able to do that you can't just set it down anywhere and expect it to charge.
If it were possible to set up charging from a telephone mast miles away you would be dead from cancer (from the radiation) or cooked long before the device was charged up.
Take your own advice.

Hi, simple math problem here. The cost of a nexus 7 1st gen (around USD 130.00 used on ebay), plus getting a coil from another device (USD 25.00 if you dont have it) maybe a broken palm pre or a touchpad on ebay, also a touchstone charger (maybe USD 25.00 on ebay) (you could also get a QI coil from another device, but then you will need the QI charger, and thats more money), That's USD 180.00, plus the shipping and the trouble of doing the mod and maybe breaking the damn thing. Let's say USD 200.00, the new nexus is USD 229.00 (IS IT WORTH IT).

You are wrong. You can wireless charge your phone (if it's capable of doing it) from the QI charger to the phone itself.
We know the QI charger must be connected in order to give power, but YES you can wireless charge your phone. I personally like to plug the damn thing, but is nice to just place your phone on the QI and let it charge by doing nothing else.

You've missed my point, sure there's no wire connecting the phone and the charger but you still have to put the phone physically 'on' the charger plate. I have a HP Touchpad and Touchstone and it's great to be able to just sit it down on the TS to charge but if I'm sitting on the sofa using it and it's low battery I have to stop using it and put it back on the TS charge it up, or plug a cable into it. In the real world you can call it wireless if you like but it's still got to be connected.

Car charger (Fast)

Hi all,
Can anyone point me to a known car charger which fast charges the G2? (Preferably not a $30 charger)
All but one of my previous car chargers only slow charge. I also just bought 2 from Amazon which claim to be 2 amp, but they also slow charge (just packed them up to go back).
Thanks.

It's my understanding that you can make one by shorting the data pins in a USB cable, but just remember to never, ever use that USB cable on a PC or else you'll damage the port.
I, too, am frustrated by LG's attempt to thwart fast-charge via normal USB cables. Once we have custom kernels, this will likely be resolved. I used leankernel on my GNex and had a fast-charge widget that would let me go from 0 to 100% in about 45 minutes.

This makes some sense as my previous phone was a GNex running CyanogenMod with Franco Kernel. 3/4 of my previously working "fast" chargers only slow charge my G2.
Strangely, when using LG's USB cable plugged into my laptop's USB allows fast charging.

I use a Palm car charger, it's the best one I've ever found, and they can usually be found for around $10. It will fast charge the G2, tested and confirmed.
Okay, I take it back, it doesn't stay on fast charging. After a minute, the slow charge notification pops up. But this is the fastest car charger that I've ever found, and I looked around for a while.
The G2 is capable of an even faster fast charge than what we are used to, and that's why other home chargers also show slow charge. It's not really slow, just not as fast as it could be.

How in the world??

It's a Nokia wireless charger stuck onto an igrip alumina car mount. And wired into a 12v outlet.

I bought this at Walgreen and seems to charge just as good as at home. 10 bucks the blue led is a little much at night tho..
Oh they come in any color you want. I use the cable that cane with my device that cable is thick so I'm assuming it's needed.

Yes, you are correct. But it seems that they are going "the extra mile" to make it more difficult...
For example, when I use my GNex USB adapter, it says "slow charge"... When I use an Apple wall charger, "slow charge". Unless I use LG's cable. I can't get fast charge to work with anything at all unless I am using LG's cable. Even then, it may or may not work with the non-LG adapter.
Can't wait for a kernel that has fast charge enabled. With the wireless storage feature of this phone, there's no reason to use MTP anymore, IMO.

So is it the cable or the 1.8a "base" that enables us to fast charge?

I'm 90% sure this has to do with the cable. Most premium USB cables are 24awg/28awg (power/data). The LG OEM cable is 20awg/28awg, and I'm guessing the phone detects the voltage drop in order to determine slow vs fast charge. FWIW, going from 20awg to 24awg yields an increase in resistance of 2.5x. I may be off base on this being the underlying cause, but I cannot think of any reason why I can fast charge on my 2.1A car charger only with the OEM cable, just like with the OEM wall charger. I'm going to hunt for a 20/28 USB cable to test this theory. In another thread, I said I was able to fast charge with regular USB cables on my car charger but I couldn't replicate it today. Phone would slow charge in all instances of USB cables, modified or not, on my 2.1A car charger.

yes, the cable is a difference.
other cables only show as slow charge with the same adapter.
now where to find these lg usb cables

What about this car charger on Amazon?

My Motorola car charger has been superb. It has consistently outperformed any and all wall chargers.
http://www.amazon.com/Motorola-Vehi...80004218&sr=8-1&keywords=motorola+car+charger

I bought amazon brand micro usb cables and they worked with the oem charger so they must be good enough to handle the extra load.

Is anyone else having problems with certain usb cords working? I have a 2.1A dual usb car charger, but only the stock G2 cord works for charging!

Yup, it comes with a 3.0 cable. It looks similar to the 2.0 cable, but if you look closely, there is a difference.

quick question 3.0 only affects transfer speeds when connected to a computer right? for charging it's always going to be the adapter's output (2A)

If connected to a computer that has a USB3 port, it'll be a faster charge than if you were to use USB2. USB2 has a max of about 500mA, theoretically. USB3 has a max of 900mA. When using a wall charger, it'll be the same as USB2, since the adapters output (most commonly 2A) remains the same. That also goes without saying: Using the wall charger will always be faster than using a computer, since the output is considerably higher.

When using a wall charger, it'll be the same as USB2, since the adapters output (most commonly 2A) remains the same. That also goes without saying: Using the wall charger will always be faster than using a computer, since the output is considerably higher.

im guessing the wall charger that comes with the s5 is only a 2A output ?

I'm not sure, since I don't have my S5 yet (getting delivered tomorrow) but yeah I'm assuming it'll be 2A as well.

I asked somewhere else and a user told me it's been upgraded to 2.5A.
The M8 meanwhile, is still 2A. heheh

It's USB on one end and a really odd looking connection to the bottom of the phone. Don't know what it's called.

Thats the standard USB 3.0 Micro connector. Its basically the standard USB micro connector we are all used to with an additional set of pins on the side. The nice thing is the ports are backwards compatible but with slower speeds.

If it's been upgraded to 2.5A then that explains the super fast charging speed.

Just got my S5
And nah, the wall adapter is still 2A...at least the one that came with mine is:

I think the fast charging is because of "Quick Charge 2.0" from Qualcomm's 801 chip.

My wife got her shimmery white phone yesterday that came with a white cord and charger and I was hoping my black on would come with a black cord and charger, no such luck, looks like they are all white.

Can I use old micro USB charger/cable from S3 to charge S5?

Yup, you sure can. The USB3 port is backward-compatible so any of the old USB2 microUSB cables will work just fine.

the 2.0 cables seem to charge extraordinarily slow for me. The 3.0 cable from the same 2A source seems real fast.
Not sure if it is just the first impressions or an indicator that you should probably plan to use the 3.0 cables from now on...
