I went from an OG droid to the revolution. The car charger i used to use for the moto droid was charging that phone very fast, just like the ac charger. Now with the revo, it's pretty damn slow. I tried shorting the data pins with some solder and the revo actually dropped about 200mv worth of charging current. Strange. I thought shorting the data lines together put the phone into fast charge but when i "cat /proc/kmsg" it says "charging at 0mv" even though it is actually charging at about 400mv as verified by a ammeter. My home charger gets "charging at 1800mv". Some strange stuff. I'm gonna try the ipod method of 2.8/2.0 unless someone else can chime in here. Thanx
I'd be interested in this also. I'm using New Trent USB battery pack and I want it to be acknowledged by the Power Manager as a fast charge source -- not the "computer connected USB" source it shows as now.
I use a store bought adapter, with the verizon/LG cord I got with the phone, and if I use Google Maps and Navigator, I lose power while I am plugged in. Glad to see I am not the only one with the "issue"
I figure its just the way the phone charges, not anything to do with any bugs or what not, so I never really worried about it. I just make sure I am fully charged before I need to use the power sucking apps.

On USB "computer powered" I've found maps and weather apps suck battery much faster than it can recharge. I noticed that the car adapter is detected as "AC Powered" -- even though it's starting off as 12VDC. I was hoping to use the external USB battery pack to keep the internal battery full while using the maps and weather in our boat --- but after 5 hours with screen on and battery pack attached at "USB Computer" recharge rates, the internal battery was flat-out DEAD, and the external pack was only down about 35%.
We just need to figure out what the data lines want to see for a "dedicated charger" type-2 charge connection which will yield the full 1800mv like the ac charger does. I'm working on this...hope i don't fry my phone's usb controller
My problem is, i don't have a charger that shows up as such. My friend's last night did, i may try to get that from him and sniff the connection for resistance values etc.
Hey...I'll leave that level of wizardry to you! Good to know there is a possible answer.

High Speed Charging
Dear All:
I do alternate energy research and we deal with Li battery packs all the time and have seen fires from improper charging. It is okay to advise rom and other software mods but when dealing with electricity it is possibly life threatening. We do not want to read in the next days post about a member dying in his sleep due to a fire. Please use utmost care when you post soldering and wireshorting hacks. We do not know the technical level of the person on the other end.
Second-most, the quality of third party chargers is very shoddy and they do not follow IEC or UL codes which adds another danger factor.
For example I bought a Chinese made Lamptron inverter for my cathode lights and the input wiring was wrong could have fried my gaming rig if I didn't check.
I understand your convern but 1800mA is the charge rate of the wall (ac) charger. That's what we're trying to achieve with a car charger. If you buy crap you're asking for problems. Most car chargers can output 2 full amps @5v but are setup to only charge at 500mA. USB charging of smart devices utilizes the data+ and data- lines as charge mode indicators. Small changes in resistance (therefore voltage) changes how the phone will pull amperage. I think everyone knows the danger of overheating lithium-ion batteries. We're not trying to do anything more than what the wall chargers already do. Check out xda a bit more and you'll see lots of posts about this very subject for different phones. Like this one. Or check out Ladyada's ipod charging research for some other good info. FYI, a good source of CCFL inverter parts is in old broken lcd tvs. Cheap, easy and reliable.
Now that that's out of the way, i set up a breadboard today so i can check some things out but had no time to test so hopefully tomorrow i can give some insight as to what the revo wants data line wise so it goes into "type 2" 1800mA charge mode. Will post with what i find and maybe some pics.
Alright. I just dug in for an hour and found out some things. My wall charger supplies 3.68vdc on both the data+ and data- lines. While using this charger the phone (using /pro/kmsg) goes into "type=2" charging mode with 1800mA. So. I hooked up my car charger. I noticed 2.1vdc on only one data line. So i made a quick resistive divider up to bring both data lines up to 3.68. BAM...didn't work. I also tried shorting the two data lines together while at 3.68v....nope. Then i threw a potentiometer in between the two data lines and tried a few values up to 200ohms....nope. I then pulled all connections to the car chargers data lines and supplied a fresh 3.68v to the output cable...nope. Last thing i did was just use my power supply to supply the 5v and gnd without the car charger in the loop....still couldn't get a type 2 charge. I'm losing my mind here. I think i missed something stupid or am over thinking this. I might start from scratch later but first, i need a few cigarettes. I'm hoping someone can chime in with a simple fix and call me stupid
I found another charger i had bought from radio shack a while ago. It's a PointMobl charger. Plugged it in and got an 1800mA type=2 charge. Sweet. Now i'm gonna dig into it and see why it works....plus i'm ditching the damn spiral cord cuz they piss me off.
I'm using the wall charger from a Moto Razr, and it puts the Revo into fast charge. I found the pinouts here: http://pinouts.ru/all/razrv3_charger_pinout.shtml
Any new insight from that?

Some phones are like that. Common usb is 4 wire, micro usb adds another pin. That pin needs to get a 200ohm resistor jumped to the shorted d+/- lines. The thing is, the wall charger only has 4 pins like every other usb. Unless the cable itself has the extra pin connected to the data lines through a resistor, it still doesn't explain the difference. I haven't taken this other charger apart yet, actually, i don't think i can without destroying it as it looks to be sonic-welded at the seams. What happened to the old screw-ended cig lighter adapters??

deftonesmw,
I wanted to say I'm looking forward to your findings. In the meantime, I ended up buying a car charger that claims high ma charging. It sounds like Danzdroid has issues with his battery pack charger which could possibly benefit from your research too.
Wall charger: 100 to 120 AC converted to low voltage dc
Car: 12v DC no conversion, probably resistance regulated.
Stating the obvious the wall charger is a complete different beast from the low voltage computer/car charger. With out a 12v dc to ac converter I don't think you will ever get a car to charge like a wall charger.
Your radio shack device probably uses some type of capacitor device to ramp up the juice then runs it through some sort of regulator which simulates the AC style charge.
Or at least if I was designing one that is how I would do it.

My car charges like a wall charger. It's not about inverting alternating to direct. It's about getting the phone to pull the amperage. Regardless of what the max current is, the phone has modes of charging. It will pull what it's directed to pull depending on the charge mode it's put into by either d- and d+ voltages and/or resistance across certain conductors. Most car chargers can produce a full 2 amps, that's not saying they are actually doing that though. It all depends on what the phone is taking, not what the charger is giving. You're looking at this the wrong way. 90% of chargers are capable of the output (dc car chargers), it's the phone that desides what to pull according to the chargers instruction (data lines and/or 5th micro pin). The charger's maximum output is equal to the fuseable value it contains. So. Yes, my car charger charges the same as my wall charger. By the way, capacitors by themselves store energy, they don't "ramp" anything. The only caps in my car charger are for smoothing as far as i can see. It's all about resistance, not capacitance. A wall charger is just a car charger with an inverter before it in the sequence. In fact, you could open a wall charger up and split the two circuits, apply 12v to the dc half's input traces and get the same effect....without the ac components even in the same room.
20 buck solution.
Buy inverter.
plug in AV charger.
Enjoy AC charging in your car.
I'm working on a real solution to this but for now an inverter is a good workaround

I went to Radio Shack today and got one of these. It shows up just like the ac charger does. I will be able to use it in my car dock for navigation and not have to worry about the running the battery down. At least that is what I am hoping for.
Anyone know of a good quality usb charging cable that will charge the phone at full power, isn't super expensive, and is longer than the stock one? The one that comes with this phone is just too short for me. I even tried my galaxy nexus usb cable, but it the phone says it is charging at a slower rate.
I'm using my Charge's cable with the LG adapter and the charging is quick as heck. BTW, I went from the Charge to GNex to G2 as well lol. Loved each upgrade!!

Quality is awesome and they are about 1.5m long. Stable for data and charging. :good:
I'm just using a cheap USB extension cable inbetween the LG charger and stock usb cable. Works fine, charges fast, doesn't give the "slow charge" notification.
I agree with the USB extension cable. I really dislike the durablity of micro USB, so I would rather use the stock cable with an extension than a cheaper built long cable.

I have an HP Touchpad, and it comes with a cable that looks identical to this. When I try to charge my phone with it, I get the "not compatible" message and charging is disabled to prevent damage... The cable may be different on the inside, but I would think the tablet cable would allow faster charging than the phone.
Alright... so far I have come across 3 different charging scenarios.
Charging with fading red LED - fast charge
Charging with white LED - medium charge
Charging with white LED + message "slow charge" - slow charge
I hope my interpretation is correct. So far I'm using my 2A original Asus charger from transformer prime and USB2.0 Palm-pre cable (which I posted above) and I'm getting fast charge (red glows, super speed). Now I only have this setup at work.. so I'm bearing with medium charge at home.
Trying not to use the original charger/cable, so I can have high resell value

Yeah seems like usb 3.0 cables have an extra connector that is not compatible with the G2. Can you possibly confirm that the cable you recommend will charge at full speed with the OEM LG charger? I'm wondering if it's either the charger itself that needs a certain cable or if there is something specific to the cable itself like the gauge of wire that is affecting charging speed.
I think you have to use the charger> 1.5A with good cable

Alright.. one thing I can confirm is that the charging speed depends on the charger.. not the cable.
I tried my fave Palm pre cable which I recommend into a slow charger and the message "slow charging" did come up.
And I also used this cable to the port that gives me medium speed.. and true enough, it was charging with white light, without the "slow charging" message. It is clearly following the charger, not the cable.
Electrically I don't see how cable should affect this. I know Samsung devices charges faster if the data+ and data- pins are shorted. Not sure about these LG ones. However, charging happens simply on the +/-5V lines.. it can't get any more complex than this.
---------- Post added at 01:10 PM ---------- Previous post was at 12:53 PM ----------
I just tested my McKal 2.1A charger, S3 original charger 1A and HTC original 1A charger.
All of these did not say slow charging, but they didn't have the glowing red LED (fast charging) either.
I guess I'm lucky I have my Asus transformer prime charger to get fast charging..
I know this Asus charger is a USB3 one, BUT only Asus propriety cable for the Prime tablet uses the USB3 pins. I'm sure that my cable is not a USB3 one.
I would like to know specifically a charger I can buy on Amazon prime preferably, that will fast charge... (car charger) I don't want to guess... so who has one that works- that you own and use and KNOW works.

I hate to argue with you, but that's not what I am seeing here.
Using the LG charger and cable, I get fast charge.
Using the LG charger and any other cable, it immediately gives me slow charge. I've tried about five different USB cables. A BlackBerry branded one, a Duracell one, the white Amazon Kindle one, an old HTC one, and my old GNex cable. The only one that gives me fast charge is the LG supplied cable.
I bought a USB power dongle that has selectable modes of operation (Samsung charge, Apple charge, and "data pass-through") and will deliver 2.1 amps from a standard USB port. It's Chinese made so I know there might be danger of blowing the power on a USB port, but it's what I've got to test with. I can't get this phone to fast charge in any mode at all. With the GNex, it charges fast. With my iPad, no sweat.
I can confirm this. Charging speed definitely depends on the cable. Here it's the same as with you - the only cable that delivers full charging speed (approx. 1600mAh according to BMW) is the supplied LG cable. The worst one (100mAh) is an old Kindle cable. All other cables I have are somewhere between that. None is "faster" than 1000mAh. The main visible difference between the LG cable and the other cables is the thickness. The LG cable is the most thickest. From my other cables, the ones that reaches approx. 1000mAh are also quite thick (but not as thick as the LG cable).
Then I received my free LG PD233 Photo Printer today (amazon preorder offering). It comes with a 1200mAh charger (the G2's charger has 1800mAh) and a very similar looking cable. It's a bit shorter and white. With this cable I have the same full charging performance.
So obviously LG spend some more cents on better-quality cables. However, given that there are plenty of high-power wall and car chargers (with 2000mAh and up) available on the market, one should assume that there should also be cables available that can be used with this chargers. I just didn't managed to find one yet.
I use a USB extension cable to charge the phone battery takes 5 hours, while normal rechargeable battery takes only 2 hours

I completely agree, I've also noticed is that the LG supplied cable is unusually thick gauge wire compared to other micro usb cables. It's 20 gauge wiring and fairly short, which means that it has extremely low resistance to current. I mean unusual, in that I literally cannot find any micro usb cables that thick for sale and I have been searching online. Part of the problem is that cables are usually not listed online in terms of the gauge of wire, which combines with the fact that micro usb cables that thick aren't common, yet. That's probably the reason that no cables that people are trying are working with the stock lg charger at full charge.
If anyone can find or knows where to buy 20 AWG micro usb cables or thicker, please post the source here.
The cable for the G2 is a lower gauge because of the higher amperage charge rate. Which is why the GNex (what i upgraded from too) cable charges slower, its only guaged to be sufficient enough to carry a .15A charge rate. The G2 charge rate is .3A, hence the reason why they used a larger cable.
So, the G2 can recognize the resistance and slow down charging on lower-gauge cables it seems? How very UA-approved of them...
Now, the hunt is on to find heavy gauge micro USB cable...
Perhaps this?

I've been looking for a 24/20 AWG micro USB cable for a while now. I haven't been able to find one.
Interesting find you guys..
Guess I was wrong after all. Also something to note is that with my fast charging cable directly connected to the phone, all is well. When I run it through my Samsung S4 charging dock, it slows down.
Perhaps it's time to email LG about this? Would be a valuable question..
Also, I still stand by the fact that my palm-Pre cable is capable of fast charging, at least with my Asus transformer prime charger. I haven't even started using the original charger/cable..
This is the exact package which I ordered:

I have not managed to find an aftermarket cable that will charge at more than 1amp. Anyone know of an aftermarket cable that actually is capable of 1800mA? I've tried nGear and monoprice, and while they are very well constructed cables, they will only charge at 1amp or less with the n7100
Thanks for the help in advance, but please only respond to this if you've actually tested the cable with with the Galaxy Charging app or a current meter of some sort. I'm not interested in cables that only work anecdotally.

I'm breaking your rules (gasp) but as far as I'm aware, it's not the cable that manages the charge, it's the power adapter that feeds the usb, right? I've used all sorts of random cables on my travels for work, but always sticking to my 2+ amp output charger, and they've always worked.

Find a very short cable and you'll see rates up to 2100 ma (as measure by battery monitor widget). I use the short usb cable that came with my jambox combined with the the phones stock charger. The charger gets so hot due to the high current that I worry if it might burn out. The cable is very short, like 6 inches. I use this one when i need a quick bump before going out.
At this low of voltage plus high current, the shielding on most cables is not enough to protect against the voltage fluctuations caused by the high magnetic field. The longer the cable the more shielding is needed. Additionally, the cable shielding gets less effective as the cable gets older due to general wear. My original usb cable can only due around 740 - 1250ma, where it used to do 1800ma when new nearly 2 years ago.
If you could find a cable where there the positive and negative wires are separated in parallel strands like traditional AC power cords, it would also help. I have a cheap charger with built in cord like this and it charges consistently fast.

Most USB cables will work with the charger, but some cables (usually longer or smaller gauge wires) will restrict the charge to a lower amperage. I still haven't quite figured out how the phone knows what cable is being used, because, realistically, in a simple DC circuit, the consequence of using a cable that is too small is heating up or burning out. A cable that is too small alone will not prevent too much amperage from going through itself. This is why they invented fuses. Somehow the phone detects the gauge/length of cable being used and restricts the amperage being pulled from the charger by changing its own resistance on the circuit.

I suspect you're right. The impedance of a cable is the only thing that would change over a period of time that would result in a cable that could once pull 2A to start pulling less than that. Still, it would be nice to have a list of chargers/cables that consistently pull 2A before dropping $15-$30 on one of them. There exists such a list on this forum, but it is filled with comments like "It's good enough for me", without any real data as to what performance they are getting. Hence my rules above.
The charge rate depends on your kernal not the cable. I use Agni and get over 2 amp charges from a USB cable I paid 12 cents shipped for on eBay.
I purchased this cable about two weeks ago and it delivers!! I can charge my 9300mah Zero Lemon battery from 0-100 in just under 4 hours. Stock battery in about 1.5-2hrs. Of course I'm using a 2.1 amp charger, but NONE of my other cables come close. I'm averaging 1800-1900mah charge rate with it. Next highest rate cord only gets about 1200 max. I plan on ordering 2-3 more. $5 and change with PRIME.

Thank you! This is exactly the type of review I was looking for!
:laugh:
Check this out. http://voyager8.blogspot.com/2013/04/how-to-choose-good-usb-data-and.htmlI found it while looking for the 6ft cable I used to use until it shorted from heavy use (bending a lot) and I got a pack of 10 short flat wire style 3ft cables. My 6ft one has a ferrite end and printed on it: 28agw/1p and 26awg/2c. It could handle 2A just fine, but this requires any wall outlet adapter that can output that amperage. The oem outlet adapter that comes with the phone says 2.0A output, but you can fine any 'reliable' one that has 2.0A output.
if the original cable is not 1800mA, there must be a reason

Hi
Hard to get something original for samsung nowadays
I have those monoprice cables but get different results every time I plug in (1698ma, 1300ma, 600ma, 460ma, etc...)

I purchased this cable about two weeks ago and it delivers!! I can charge my 9300mah Zero Lemon battery from 0-100 in just under 4 hours. Stock battery in about 1.5-2hrs. Of course I'm using a 2.1 amp charger, but NONE of my other cables come close. I'm averaging 1800-1900mah charge rate with it. Next highest rate cord only gets about 1200 max. I plan on ordering 2-3 more. $5 and change with PRIME.

Which 2.1 amp charger are you using? I have one for my car, looking for one for home use. I also have the 9300mah ZeroLemon battery in my T-Mobile Note 2. Thanks!

I was using the 2A charger that came with my Nexus tablet. But I bought an additional one for work.
iXCC ® Dual USB 4.2 Amp (20 Watt) SMART High Capacity [High Power] ... http://www.amazon.com/dp/B00HPTU0OU/ref=cm_sw_r_udp_awd_PR7.tb01EM5CB
$11.99 thru PRIME.
Had this one for almost 3 months now and it works VERY well. I get a full 1900-2000mah charge rate on the Note2 and can charge my tablet at quick speeds simultaneously.

some fake cable limit current.
Got similar problems as the OP. I wanted to charge my phone in my car and using the phone as a navigation device without depleting the battery (which occured a few time).
Tried several usb cables, even did some mods like shorting the white and green data wire in the cabel at the phone side, but that all didn't help.
Then i came to Kopi who sells usb cables which can deliver a full current.

Bought a few for 6 dollar each and am now a happy camper.

I just saw it. Why don't you email them and ask about availability? I had contact with Victor Leung ([email protected]).
My touchpad charger is starting to smell like smoke and make loud crackling sounds. Probably not a good thing.
The interesting thing is that I once read this super-in-depth technical comparison of the touchpad charger with a bunch of other chargers, and the touchpad charger was leagues beyond them in quality. Yet it is the only charger I've ever owned that has developed obvious problems.
The wireless charger is too expensive for me, although it is tempting.
Does anyone know if it is fine to power the touchpad with a more generic wired power supply?
I bought this on sale for $12.99: http://www.bestbuy.com/site/insignia-2-outlet-surge-protector/5741111.p
But I'm afraid to plug in the touchpad to its USB port (using the original touchpad USB cable) because it is 5V / 2.1 Amp and the touchpad original wired charger is 5.3V / 2.0 Amp.
My amazing math skills tell me that is not enough V and too much A. If that matters, I dunno. All I know is I don't want anything catching on fire or anything breaking. Also since the touchpad battery is not really removable, I don't want to do anything that will reduce its lifespan.

I use a generic charger similar to what you describe without a problem. Expect it to take longer to charge, however.
The Volts and Amps are no problem, the issue is how fussy the touchpad is, it's seriously picky and complains at most chargers.
You never want to go over on volts, so a little under is fine. Amps, the device will only use what it is spec'd for so you are good there but you really want at least 2. The Touchpad can be picky. People will spout the "Only stock chargers will work" myth until their faces turn blue. Then you use TPChargeTest to show them it is working and they will blow it off saying that it anomalous or some other nonsense.
Download the app I linked and run it while charging. You currentnow and currentlimit will tell you how the device is charging on the charger you are testing. Ideally the currentnow when charging will say 2000ma which means you are charging at full capacity and the currentlimit will show a positive number. If I remember correctly it has to show at least 1200ma to actually charge the TP, while on, and it will be slow. Any time the currentlimit shows a negative the unit is draining, not charging.
I've successfully charged the Touchpad with a Nexus 7 charger and my HTC phone charger. Just make sure that the charger is from a reputable source (i.e not ebay).
Hello,
First time poster long time reader.
I have read 20 billion forums where people continually say that "everything charges a touchpad" and "nothing charges a touchpad but original charger"
we are 5 years after launch and crash. Judging by forum activity people still have and use their touchpads.
what charges a HP touchpad? Do you need a special cable? Do you need a special charger? can some one after all this time give the definitive answer?
I have read through many posts on this forum and multiple others and it seems this question has not be clearly answered.
im looking for a "only a hp charger" or "500v and 90a will do it" or "connect nipples to car battery and furiously tongue the charging port".
to understand why I am asking this question. I dont have my original charger and i dont want to pay $40 for an american charger ( I dont live in America) I use a 5v 2.1a phone charger and it gives me the "to reliably charge" screen.

Some are more picky than others, but I charge mine with any 5v, 2a charger. Time to fully charge varies, and if you use it while charging, it will not store much in the battery. Put it to sleep and let it charge until full.
So its more picky,
I am currently using a Belkin wallcharger that outputs 12w 2.4A. I have left my tablet plugged in and off for the last 24 hours and it wont turn on other then to tell me that to reliably charge I need the original charger. I have KK 4.4.4. Is this a typical charge time for these in other users experiances? how do we get it to charge with out an original cable or wallcharger?
I too would like to get to the bottom of this. I use the original charger and cable and from a dead battery takes a goot 15hrs before it boots up. The only indication its charging is the home button LED that flashed back and forth. I've tried 3rd party chargers and none work. I've tried 3rd party cables and none work.

It is a well-known fact that allowing the battery to fully discharge is problematic at best, disastrous at worst. None of the chargers are reliable when this occurs. The simple answer is don't let the battery go below about 10% before recharging, or you may not recover your tablet without having to debrick it.
This has been my experience:
Any old charger and cable will charge a Touchpad so long as the battery isn't completely dead. If the battery is completely dead, then there is a way to get enough power to turn it on without needing the original charger or cable. You simply plug it into the USB port of any computer and let it sit. Let it sit for a long time. I let mine sit for a day before trying to power it back on.
YMMV, but I've had success with that method.

You are right about the many discussions about what chargers work with the TouchPad and which ones don't. I have sat in on many of them as well as done some testing of my own. The rule of thumb is it is best to use the official HP TouchPad charger. HP for some reason made the charging circuits proprietary on the TouchPad so that if you use a third party charger rated the same as the official one, it will charge but only at the lowest rate of 500mA. You can also charge the TP from a PC usb port, but again it is rated at 500mA. The catch is the TP uses more than 500mA when awake, so to use one of these methods, the TP has to be put to sleep or be turned off and will charge very slowly. That being said, you may find a third party charger that will charge the TP at the higher rate, but they are rare. At one time I was aware of a user who was modifying USB cords so that you could use a third party charger. He used to have a thread on RootzWiki forum, but that that forum was pretty much destroyed by spammers and his thread was lost. He had instructions with pictures and parts lists. Also, keep in mind, any good USB cable will work with the original HP charger. It's the modification that he was making to the cable that tricked the TP into thinking it is connected to a real HP charger.
However, I did find this post from a fellow that knows the mod one needs to make to get a third party charger to work with a TP:

I have confirmed all that you have said and now know this to be the definitive answer, since OP I have purchased 12 chargers advertising different automatic charge regulation features such as belkin "smart" chargers, none would charge over 500ma which of course as we now know is not sufficient to use the TP and takes days to charge, not what i would call functional.
I made a messy hack job charger.. im definitively not great at that and between an accident prone wife and 2 small children, my end result wasnt good enough to let charge alone next to the couch or something.
Finally, while i did all this I had a HP charger on order with an American wall plug ( i live in western Australia so different plug and long postage time) this charger works as expected and in my research was the only functional way to charge the TP
THANKS TEAM. we got there in the end.

In seeking the same answer as you I seem to have stumbled upon a couple options that explain the answer...
Here I wanted to post a "Screenshot of HP forum answer regarding HP Tablet charger reqs" but the forum bots won't allow it...
So the screenshot the i wanted to include above will not post properly, i'll explain... the screenshot showed a h30434.www3.hp com/t5/Tablets-and-Mobile-Devices-Archive-Read-Only/Need-a-charger-for-my-HP-10-2101-Tablet/td-p/5962461" post on the HP support forum of someone asking basically the same question... specifically about the HP 10 2101 Tablet... forum user "Wyrenut" (has over 16,000 posts on the HP support forum) states confidently;
You can find one at pretty much any computer/electronics store, or online at amazon comIt just needs to be rated for a tablet - providing at least 2.0 amps of DC current and at least 5.3 volts, and a micro-USB port on the tablet end."
This seems to check out thus far in this quest for tablet power because I was able to find in my adapter bin a 5.1 volts DC @ 2.4 amp charger with a micro-USB end and after hours of being plugged in, and that has failed to charge an HP TouchPad 32GB I recently acquired without a charger. So I am currently seeking an adapter that will satisfy "Wyrenut's" stated requirements for an HP Tablet charger and once I get my hands on one, we will have the definitive answer and I will followup on this thread as well.
Useful infos to include in the definitive answer...?

Yeah, I found the Touchstone charger as well. I think that's probably the best choice, because not only is it pretty cheap and gets me a stand, but it also comes with the original barrel charger required for the proprietary HP charging circuit to use the full 2 Amps. (So I assume I could then use that barrel charger with a micro usb cable as a wired charger if I didn't want to use the wireless stand)
Still, I'm impressed a 2011 device has wireless charging. If I do buy that Touchstone, I'll probably just use the wireless charging for convenience.
Anyway, I first need to get this thing to boot. I have the (seemingly) common dead battery issue. I received this tablet from a friend for free, he said it was barely ever used and then put away in storage. The tablet is in like-new condition, so I believe him on that.
I've plugged it into a 5V 2A (10W) USB charger from a Moto G Pure, and it's currently alternating between two lights on the home button. (And has been doing so for the last 8 hours or so). I'll leave it overnight as well.
At that point, I assume I should start trying power vol and home button combos to try to turn it on? Do you have any suggestions on what I should do to get this tablet to boot?
Once I can get it to turn on, I'll probably look into getting the original charger (that Touchstone). Until it works though, I don't really want to invest $12 to $16 into this thing and then be left with a useless wireless charging stand.
I assume using a non original charger for now shouldn't be much of a problem apart from the charging being slow. It'll still charge, after all, even if at 500mA.

There is no special trick, just charge it in a warm room temperature above 80F with the right charger. Lithium batteries does not charge well in cold.

Ok, well, I don't have anything at 5.3 exactly, only 5.0V. I guess I'll go and buy a touchstone charger so I get the stand and barrel charger, so that it has the correct output. I really didn't think 0.3V would make much of a difference though.
Anyway, once I plug it into the original charger, how do I know when it is ready to turn on? Will it just turn on by itself, show a charging icon, or something else?

It could probably work, give it a try.
1. LED light blink from side to side. ( The tablet's battery is depleted, but taking charge ( awake ). Leave it until it boots, it could take a week.
2. Second stage ( a battery sign with a red line under it ) will show on the screen.
3. It will boot.

Welp, I just bought a TouchStone. The eBay seller was surprisingly fast at replying to my offer, so now I have an in-box TouchStone charger arriving in a week for $13 and free shipping . Not bad.

Great !
The TouchStone for some reason charge faster and better that USB.
Always keep the Tablet charging, never let the battery drain.
Have FUN!
