After using a wall adapter to micro USB port charger that only supplies 0.7 A instead of the 1 A the stock charger does, the lower adapter got very hot. Does the phone still try to draw one amp if its not connected to a PC through usb? Considering the standardization of micro-usb it would seem like G2x owners will try to use chargers at friends houses for other phones and it may not be the safest thing. Any input?
My factory LG charger only provides 0.7 amps.. but I use my hd2 charger that provides 1 amp cause the phone charges a little faster on it.. so I don't understand what your actually trying to say?

Phone can only draw as much power as the charger supplies, up to something like 1 amp. If the charger supplies less than that, then it only draws what the charger supplies. If the charger supplies more than 1 amp, then it will still only draw the 1 amp that it needs. The more important thing to ensure is that the voltage of that charger is the same as the stock charger.

It's strange we got different chargers. This one outputs 4.8V at 1.0A. It also squeals when the phone is in standby. If i wake it it stops humming. Model STA-U13WR2. I wonder if charge rate has to do with anything bad? When the charge says completed and it is plugged into a USB port, it will charge for another hour at times. Makes sense since a high charging rate will cause the battery voltage to spike and read as if the charge is complete when it's still got room.
I lost my wall charger that came with my HP touchpad. The round plug thingie is what I'm looking for. Searching on Amazon brings up a number of items, for example:
http://www.amazon.com/HP-North-American-Charger-TouchPad/dp/B0055QYJJM/ref=dp_cp_ob_e_title_3
However, is there an alternative that works? I was able to use the Evo cable rather than the original HP sync/charge cable that came with the wall charger, but is there an alternative wall plug that works as well? Paying almost $28 for a charging cable seems a bit ridiculous.
Any help and advice would be most appreciated.
[[FOUND MY ANSWER]]
I found that Walmart was having a sale on the North American charger with the barrel wall connector for $11.99 and Meritline was having a sale for 6' long USB to micro-usb cables (pair for $4.99 no tax/shipping).
The listing on the Meritline page says that the cables are compatible with the Evo.
Given that the cable that comes with the HP barrel charger is pretty much monkey spit and fails within a month, I found a solution that works for less than $20.
Links are below:

Meritline Cables (use this code MLCK222YNL1 for discount (cannot guarantee how long this code is good for, drops the price for a twin pack of the 6' cables from $10.99 to $4.99)

Pretty much any USB charger will work, but most give a notification on the Touchpad screen indicating that they may not be charging. This is because the official charger is at the high end of both voltage and current capability. I charge from laptop, desktop and a variety of Blackberry chargers with no issue, but the available current will determine how long it takes to charge and whether it charges much while the screen is on. Go for a USB charger that gives you 2 Amps and you should be fine.

Thank you for the advice. To be more specific, can you recommend any alternative charging cables/wall charger units specifically?
Any brand name USB charger that gives off 2 amps should be fine. I tend to stay away from really cheap generic chargers. Any microUSB cable should be fine even a generic one if it has decent reviews. I worry about generic chargers since a poorly regulated one could send a voltage too high, but generic cables should be fine.
The chargers I am currently using, as well as the one that came with the TP, are the one that came with a Blackberry Playbook and the one from my HTC Desire HD.
The Blackberry charger gives an error on the screen that it may not charge the TP, but as it gives 2 amps, charges in pretty much the same time as the official unit.
The HTC again gives the warning and takes about twice as long to charge.
what about the nook color charger i know it higher amps might work as well

I just tested the TP with a charger for the NC, and unfortunately, it still gives the same "may not charge" warning...
There is NO after market charger that will charge at full rate like the HP barrel charger!
At best they will trickle charge at a much lower rate and take considerably longer to charge.
The TP relies on precise signaling which it will only get from the OEM item or specially modded after market units or cables.
Do a google for further info ie webosnation.com forums.
I think your looking for a 5.1v charger, aka rapid charger. This is used by the iPad, and some android phones like the Motorola droid 3, razr and htc rezound.
I could be wrong though,I haven't gotten my touchpad yet.but I do own all said device above (except the razr) and they all use the faster charging technology.

Don't believe all the hype about using ONLY the HP charger, there are many that do the job perfectly well. Too many people make these authoritarian statements and all they do is cause FUD.
At my office, I use the AC charger from my last Samsung phone (mythic) and it works IDENTICALLY to the OEM one. I have also used a Moto and and LG with NO PROBLEMS. I have no issues getting to fully charged in little time.
At home, my OEM cable is plugged into a high-power USB port (2.1A, I believe) and it has no problem charging from near zero to full as well. Front or top-mounted USB ports tend to be 500mA or less, but the rear ones (coming directly off the motherboard) tend to have a higher supply. I also use a non-HP USB cable occasionally and it works fine.
(I got my TP during the original fire-sale and have been charging it these ways ever since with ZERO ISSUES.)

The small voltage difference is marginal and isn't going to matter, the internal hardware should be able to tolerate a few tenths of a volt difference. In fact, I tested my Motorola charger rated at 5.1v and the Touchpad charger rated at 5.2v on a multimeter. The Motorola charger was outputting 5.20v and the Touchpad charger 5.16v. Granted this is at no load, but switching transformers are regulated so they should supply rated voltage at any current draw equal to or less than rated. Also depending on how well the voltage is regulated there may still be a slight AC ripple that the device has to deal with.
Does anyone know the time difference between using the TP charger and a standard droid/blackberry charger? Also curious if the charges last the same. I know theoretically they should since the battery is full either way, but electricals can be tricksiy..

Its all down to the charge rate that the TP is able to draw.
2A which is theoretically possible from TP AC barrel charger would charge the 6A+ battery of the TP from flat to full in approximately 6.5 hours.
If the BB charger were able to have 500mA drawn by the TP then it would fully charge in approximately 26 hours.
The charges would be no different.
To convert any regular USB charger into a TouchPad charger you need to add 2 resistors as per the diagram attached.
The presence of the resistors will trigger the TouchPad to draw the full 2A from the charger rather than the trickle charge it does when they are not there.
Please do not modify a cheap charger that is only rated for 500mA as you will most likely overheat it and it could present a fire risk.

Just pointing out that you need to start with a charger that is rated at least 2Ah to start with.
You can't turn a low rated one into a high rated one.

oh, for the love of gods. REALLY? I was just asking for a replacement cable. I don't want to reinvent the charging paradigm. I just need a simple recommendation for a cable. If a thread could be highjacked any further I don't know how it could be.
I appreciate all your "advice" but seriously, this is NOT what I was asking.
Anyone know if I can get a similar cable in the UK? Kind of lost my TP cable, and I miss the flexibility the long cable gave me, it was so much easier to use on charge!
well i know that my tbolt cable works. i have to use the tp adapter though. my tbolt adapter makes the touchpad say that the charger is incompatible.
I am going to buy a car charger for my new HOX, but it only has one 2.1A usb output. I know the charging current of the HOX wall charger is 1A, but I think 2.1A should work fine or even charge faster. But my concern is if the larger current would hurt my battery or shorten its lifetime.
Some ppl said the phone itself would take 1A current anyway due to some kind of threshold control inside, but I am not sure about it. So pls let me know if you know the truth. Appreciate it!
ps. I sent an email about this problem to HTC customer care 2 days ago but still no response yet. I will post the official answer when I get their answer.
UPDATE: Here is the official response from HTC about charging current, it seems that HOX does not intelligently control its charging current:
Dear yydnl,
Thanks for getting back to me, yydnl. The One X was designed with the intention of only using 5V 1A chargers. Anything more will cause damage to the phone over time. The phone was not designed to alter the current coming into the phone through the charger. I recommend that you only use the supplied HTC charger with your device.
Yeah I'd like to know. I never opened the oem charger and am currently using my bb playbook charger which shoots out 1.8A. I'm hoping the answer is no damage with a faster charge.
Yep, it'll work fine. Chargers don't "push" the charge, the phone pulls it. If the phone is only designed to charge at 1000ma, then it will only pull that current. So you could use a 10 amp charger and it will be fine, only difference is that with that high a capacity, you'll be able to charge 10 phones at the full charging rate. Changing the voltage, that's a different story.

There is no problem of the voltage of the car charger because that is 5V as the oem charger, but do you know if HOX is designed to intelligently pull the proper amount of current? or will it take any current fed to it?

All Li-ion batteries have intelligent charging circuits. Otherwise, it will simply explode.
I won't worry about 2.1A at all. The problem is other way around, i.e. whether or not the phone will take more than 500ma from your 2.1A charger. It depends on how your charger is wired. If the phone only detects a generic USB connection, it will only charge max 500ma. It requires special wiring from the USB port to allow phone to switch to AC charging mode to draw more current. Unfortunately, there is no way to tell until you have the charger and try it out. One thing for sure, those chargers designed for iPhone/iPad typically won't be recorgnzied by other phones as AC chargers.

Gotcha, the car charger I am going to buy is for iphone, but it also claims to be able to charge phones of htc, sony etc. So I guess it is possible to have the ac charging detection.

My money is on that it won't be recognized as AC charger. iPhone has special requirement on data PIN wiring that is not compatible with other phone. Yes, you can charge other phones but probably not at anything over 500ma.
Pls see my updates, it seems that 2.1A charger is not safe.
Hi.
I'm looking for an advise about car charger that can charge my TF700.
does anyone confirmed that there any car charger that works?
I mean, I saw some posts that says that ASUS' charger is 15v instead of the more common 5v?
but then I saw the charger, it says " Output : 5v === 2A or 15v === 1.2A"
So I assume I can use other car charger that works with other tablets?
can someone confirm this for me?
THANKS
The tablet will only start to detect a charge at 12V.
Charging at anything lower than that will charge about 1-3% every hour.

oh. okay. any recommendation on what charger should i get?
preferably one with dual USB.
USB is not going to work, in any form or capacity. a USB port can only put out 5V at max.
I use a power inverter that puts out 230V (bought it for my laptop a couple of years ago) through a normal outlet. Plugged the charger into that and it charges normally. You could try looking into that.

YES the ASUS Transformer will only charge from between 12 & 15V. They DO NOT charge from 5V USB.
I have found that the car chargers which have the ASUS 40 pin plug attached to the cable work fine. They have a regulator circuit which outputs 12V at 1.5A minimum.
The ones available on eBay work well and aren't too expensive. They are a little bulky because of the high current circuitry so look at the pictures and make sure that it looks bigger than the average ones and you will do fine.
unfortunately there's no car charger available as of yet.

An Carcharger is avilable, i have one and it is working. 15v 1,2A Carcharger with normal Asus connetor. I'm usin it since 2 Month, never had problems. Carcharger is even cooler as the 230V USB charger while charging. Asus Tabel also switch immediately in charging mode. 14€ at Amazon.de.
By the way, why is everyone saying 5V won't work? On my 230V USB charger there's following note "15V 1,2A or 5V 2A"
Well won't need it, just buy this one ( which i have):
www.Amazon.de/gp/product/B007PQ8AN6/ref=oh_details_o04_s00_i01
Just ignore that tf700t isn't written there and that the charger would have 1,5A. Thats wrong, Carcharger has 15V 1,2A.
If you won't believe me, i can make an picture ( that it will have 15V 1,2A and works) otherwise have fun with it

Why aren't you reading everything? I said 5V charges too slowly for the tablet to detect, but it does charge. About 1-3% an hour, which is useless when you're using it. It clearly says, in the manual, that it will only charge over USB (5V) when turned OFF and not connected to the dock. RTFM.

I don't know how many different threads I have to post this in...
http://www.amazon.com/gp/product/B0081BFYY2/ref=wms_ohs_product
Includes a home charger, car charger, and an extra USB cable, that ALL work. I have been using these with my Transformer Prime, and now my Infinity without an issue at all, and they provide the ASUS required specs for charging and work just like the factory provided chargers.
I ran into this issue with my Verizon Samsung Galaxy Nexus. When attached to a charger, if I went into Settings...Battery... it would show the status of the charging process: it would say "USB" when connected to a computer, and charged at a much slower rate, or "AC" when plugged into the supplied charger in a regular outlet, and charged much more quickly.
With most car chargers, it would only show "USB" but there are some car chargers that have the correct wiring so that it was recognized as "AC" and charged as quickly as when plugged into a regular outlet.
I have two of these in my vehicles, and I just checked one of them, the one listed below first, and with the Tablet plugged into it, it shows as charging, as an "AC" source, just as with my Galaxy Nexus.
Here is the one I specifically tested and verified that it works:
Dual USB Car Charger
I do note the 2 negative reviews there, but all I can say is that I've had this one for almost a year, and it has worked perfectly for me with my phone. A brief test with the Asus Tablet confirmed it was seen as an "AC" charger.
This is the other one I have and which works fine with my phone, although I have not specifically tested it with the Tablet (I have no reason to expect it would behave any differently):
HTC T-Mobile myTouch 3G Car Charger
Obviously, I can't be held responsible if somebody else has a different experience with these, or has problems because of it. Just trying to be helpful and report what has worked for me.

It may work, or it may not. Drawing on my experience with the Galaxy Nexus, there were quite a few car chargers that had specs like this but which in fact were seen as "USB" chargers when used with the Nexus, and I suspect would behave the same way with the TF700T.
I am not an eletrical engineer, but it has something to do with how certain pins are shorted or not, and not all chargers that say they deliver the higher amperage will in fact do so with all devices.
It'll just take somebody to buy and try, and report what does or doesn't work. Per my post above, the chargers that work with my Nexus also work with my Tablet, in being seen as "AC" charging.

I have one on order and will pick it up at my daughter's when we go to the US next month. Will post what I learn.
HOWEVER - a true "USB Charger" provides a 5VDC output, not 12- 15 VDC, as does the i-Blason unit I mentioned. Note that i-Blason states very clearly, "Warning: Pls do not use with other MP3 or smartphone... High Voltage could cause burn out."
The difference many smartphones (and other USB ported devices) detect in "USB Chargers" versus "AC Chargers" is max current available (<0.5 A vs >1.0 A) For example, I have a USB battery and a video cam that will both fail to illuminate the charging light if connected to a charging source below about 0.75 A, but still charge, albeit slowly. Both came with 1.5 A USB (5 VDC) wall chargers.
Since the i-Blason is a 12 VDC, not a 5 VDC output, the odds are high it will charge the Transformers at a rate very similar to the wall charger. At least based on electrical "theory". If I had to blind pick a third party car charger, the specs for the i-Blason, to include using the stock cable, were what influenced my choice.

Yup, the car charger still charges my old HTC, even with the Samsung cable... so there's definitely something different inside the charger...

I've got a 1A Belkin car charger and it seems to overload after a while when charging my gs4.
The green light on it blinks and my phone makes that sound when you plug in the charger.
Takes a while for it to happen but gets more frequent the longer you have it plugged in.
The charger works fine with my gf's nexus 4.

I'm using the Motorola charger (big blue circle). Got it for my Razr Maxx a year or so ago (I've gone through like 4 phones since then) and it works wonderfully. It's the best micro-USB car charger I've ever seen. Coiled cord, huge blue light (but not too bright since it's an ambient-style light), and charges quickly.

FYI the tool i use to measure says the Samsung charger is 1900 M-amps and my apple ipad charging brink is 1400 just for reference.
tool is Galaxy Charging Current Lite i would link it but the forum will not let me

You can also use elixir 2, the battery stats will give amps while discharging and change when charging. I think it uses the current_now as reference.
I have a 2a usb car charger and I just use the usb cable from the phone. I bought the car charger from best buy.

Do you use it with the original cable or a generic one? I read that there are some differences in charging amount using also different cables. This SPIGEN Car charger looks very interesting. Thanks!

Different USB cables do pass different current even if using the same charging main. From tests I've done so far, a generic 3 ft USB 2.0 cable I randomly purchased online only allowed around 400 mA. An old Blackberry Torch 9810 cable allowed around 1200 mA. Original cable that came with the S4 allows 1900 mA. These numbers are from using the original wall charger main that came with phone.

I bought an anker car charger and mediabridge charging usb cable and it's a great combo. The images of the anker car charger is different, should be dual usb ports.

I don't know the exact current I'm getting, but from the battery monitor widget app, I'm seeing at least 1amp or higher of positive current.
