Hi y'all,
I'm looking to buy some new chargers (wall charger, car charger) for my HD2 (not that this should matter, I guess it's something that applies for a lot of devices) but can't figure out which combinations of chargers & cables will really charge at 1A.
The combination of an iPod USB charger with a micro USB cable from my local store resulted in 'USB connected', and hence maxed out at 500mA. Recently also used a 1.2A car charger with a micro USB cable (both from dealextreme, being cheap =) ), and once again I got the dreaded 'USB connected'.
What do I have to buy or do in order to make my phone understand that it's not charging through USB (well, in a way of speaking) but through a wall charger?
Muchos thanks!
Edit: did some more research. Just short circuited the 2 center pins of my car charger, and now it's recognized as AC, whoo! I suppose this applies to all chargers, hence, question solved!
Anyone using this charger with their Inspire4G?
I've tried using this charger with my phone, with several different cables, including the OEM cable. I can only ever get the phone to charge at the USB rate, not the AC charge rate.
Is this normal or is my charger defective?

I would assume thats because the 2.1A is ment for Ipad/Iphone/Ipod devices as they require a larger amp charge.
The 1.0A is ment for all other USB devices.
States that in the description.
Charge your iPad and an additional USB powered device at once
Use your existing USB cables to charge any additional USB powered devices
2.1 Amp USB port for charging iPad
1 Amp USB port for charging additional devices
Were are you getting AC Charge rate / USB Charge rate ?
On both ports, I'm only getting the USB charge rate.

What do you meen USB Charge Rate..
I am going to guess ..
AC Charge Rate = Wall Charger
USB Charge Rate = Computer USB 2.0/3.0
Does car charger port provide enough amps to give full value?

when you go into Settings -> about phone -> Battery
It will show you the charging status. USB Charging typically is no more than 500ma. AC charging should be 1a.
I have an old AT&T brand car charger that charges the phone in "AC" mode.
This is were I am still getting confused.
What ROM are you running, Stock / MIUI / CM7 / or a Rom based off of stock ?
Is it 2.3.3 or 2.2.1 or 2.3.4 ?
I don't have those reading under battery status.
Anyways, I will go ahead and make the assumption that your car charger is busted and need to get it replaced.
This is were I don't get were you are stating AC Charging.
Alternating Current = AC Direct Current = DC
You cannot charge a battery " DC " with an Alternating Current " AC " period. Thats why all battery chargers reguardless of type convert AC power to DC.
Then only thing I can think of is maybe your phone can detect what type of charger it is connected to, displaying it as an AC Wall Charger or a DC Car/USB Charger.
Wall Chargers will generaly charge quicker then a computer USB Charger. Car charger typicaly charge quicker then most wall chargers.
Most Car chargers are very poor at controlling the amperage being supplied. They may stay at the right voltage but rest assured, you hit a 5v 2amp battery with a 5v 10amp charge and your going to fry it. This is the reason I dislike car chargers.
I can only see one of two problems with your Car Charger ;
1: the Car charger is bad
2: your 12 Power source port is not supplying the correct amperage that your car charger requires. IE:
I have the HTC Car dock for my inspire. It has an imput requirement of 12V 5 Amps to operate efficiently. The Power supply I have it plugged into is the 12V 20A Accesory Port in the front of my truck. It works just fine.
If your device requires say 12v 5 Amps to operate efficiently yet your car is only supplying 12v 1 Amp due to bad wiring, old fuses or bad connections your car charger will not charge at idicated levels.
The ROM is simply displaying "USB" if it is drawing 500ma charge, or "AC" if it's drawing 1000ma charge.
I'm running the 2.2.1, the LeeDroid_HD_V.2.0.0 ROM

Ok, so your saying that when you have the Car Charger plugged up and your device connected, your only getting a 500ma charge. When you use your old ATT Car Charger it shows 1000ma.
500ma = .5 Amps
1000ma = 1.0 Amps
If your not getting over 500ma out of your car charger then either 1 of two things.
Car Charger is busted, get it replaced.
Car is not putting out correct Amp - Voltage for the car charge to operate correctly.
Your old car charger could have different requirements and that is the reason it works, your new one could use a deifferent set and may not work.
Regardless, its not working in your car, try it in a friends and see if it works, if not then the charger is broke, if it does, then your car is broke.
Try usiing current widget while charging.. and see the readings

i don't know what you are talking about here. The 2.1 Amp option is NOT the AC charging rate. It is pretty clear if you look at the stock HTC charger that comes with the phone, it says it outputs "1.5 V at 1A".
And anyways...if you look at the product description on the link you posted, it CLEARLY states the 2.1A is for charging an iPad.

I've used both ports on the reVIVE II, both the 2.1a and the 1a. Both only report the phone charging at 500ma

sorry...i thought you were referring to the AC rate as the 2.1A port, and the USB rate as the 1A port.
I was looking at the Asus wall charger that came with the device and the output states 5v 2a or 15v 1.2a.
Does that mean I can use a 5v 2a wall charger to charge my infinity?
Thanks

No, but it means the Transformer's charger can charge normal USB equipment.
Hello!
I want to buy the fastest and reliable charger to wall and car (separately of curse) and I don't care if the cable comes pre-attached or it is only a USB adapter. It need to output 5v 1.2A for maximum performance right? in the place i'm living i got an LG charger that output only 5v 0.7a. so where can i buy a 5v 1.2a wall charger? and a 5v 1.2a car charger? worldwide shipping please.
any other suggestions?
thanks

I've been looking for a couple wall outlets that have the standard two 110V plugs and 2 USB ports and there are quite a few out there. The problem is I haven't found any that can charge the way the default charger that comes with the tablet charges. 5V with a USB 2.0 cable and 12V with a USB 3.0cable. Are there any out there that can do this? This would save me alot of plug space in the bedroom if so, one plug for the tablet and one for my phone.
Thanks
