I tried plugging in my mini usb cables I have used for other phones but it does not fit. It looks like the opening on the MT is larger then the standard. Is anyone else noticing this?
I've used all my other ones fine. I use a blackberry mini usb to charge while I sleep, another blackberry cable to hook to my laptop at work, and the one that came with it at my home desktop. No problems for me.
All my chargers work fine as well.
It uses microusb, not mini. The standard ones work fine.

It's not the volts, it's the amps....
Just as an FYI, one thing to watch out for even though the USB plug is standard is that the power output can be different on different chargers. 5v is the USB standard, but the amperage can vary. I think the Max is 1A for the USB (2?) spec, but I'm not sure if or what the Min amperage is. The V/A output should be listed on the charger.
The plug that comes with the mt4gs is 5V-1A. When I've tried charging phones (e.g. Blackberry) in the past with a 5V-.2A charger, it has worked extremely poorly (half charge after 12+hours). I would expect similar results with the mt4gs.
websculling is right. Additionally, using the wrong amperage to charge significantly decreases the number of charges you get out of your battery before it fails. Stick to chargers that have the amperage the battery was optimally designed to accommodate.

So amperage is what matters with USB charger compatibility and not the voltage?
My wife's old feature phone came with a micro-usb charger so I'm trying to figure out if it will damage by MT4GS or the MY3GS I handed down to my wife.

Both are important.
Too high of a voltage and you'll burn up the battery or damage the charging circuit.
Too low of an amperage (blackberry chargers) and you'll wear out the battery much more quickly. Trickling in power like that to these kind of batteries that weren't designed to handle it that way 'ages' the cells and reduces their already less then impressive lifespan.
Battery tech is better then it was even a few short years ago, but these kind of batteries in this small of a package are barely efficient enough to be useful. A few more years and things will be a lot better, but for the time being you should really try to care for your battery as best as you can and not abuse it.
I'll post the link here to the XDA battery writeup I linked to in both the anker and mugen threads later on when I get back to a real computer and am not using a phone app to browse the forums.

That's not too far out of spec, but I would rather let my battery die then use it, personally. Finding an AC adapter that is in spec is very easy and very cheap.
Something to note here is the doubleshot does not have a hardware regulated charging circuit inside the phone - this is the reason why it was rough with the early unofficial ClockworkMod recoveries and the source of their charging issues.
Knowing there is no hardware failsafe, it makes it that much easier to do permanent damage to the battery, device or both.
Do what you think is best, but just want you to have as much information as possible to base your decision on.

Unsure - this is my first smart-phone, so I don't have the history of knowledge a lot of people don't realize they possess and am playing catch-up as quickly as I can.
I know a lot about this device, and the Nook Color, but anything else is pretty foreign to me at this time.

Being the DIY kind of guy, I'm wondering if anyone tried to disassemble the Touchstone charger and post a schematic so that anyone with some electronics skills can make their own, in whatever shape or colour they desire.
Just wondering.
Ifixit has a pre touchstone tear down. They are similar, maybe you can request that site complete one on the TouchPad version.
I just looked mine over, there are no exposed screws. Any screws must be under the rubber foot, or the back may snap off. I'm not risking breaking mine. But, for $40 you could find out yourself

All you need is a USB source with an output of 5.3V and 2A. But on that note, doesn't the higher level of amps charging the TP batteries more quickly kill the overall battery life of the batteries?
I use other brands of usb chargers unless i'm in a hurry, because the TP official charger will get it all juiced up in no time. Lower amperage, slower charging, longer overall battery life (i presume.)

Not sure about the truth of that, because I think it has something to do with the actual cycles. I'm not 100% sure so if I'm wrong someone correct me.
The OP was referring to the wireless induction charging in the Touchstone, not just a generic USB charger.
As to the whole more amps = lower health battery debate, I won't touch that. I've seen "proof" both ways. What I know is the OEM charger is 5.3v at 2 amps. I am going to trust HP that is the proper specs. Plus, any "smart" device doesn't pull more amperage than it needs, so its software controlled.
Sent from my Galaxy S II (i777)
Indeed, I am not talking about the wired charger, I am talking about the wireless Touchstone charger.
50 USD wouldn't be a problem for a Touchstone. However HP hasn't brought Touchpad's or accessories in Romania and offer no support for them, and I don't want to wait for 2 weeks for delivery.
And I also am the DIY kind of guy, and in the near future I'll be designing and building a custom desk which I would like to include a nice built-in stand for the Touchpad.

Any old 5.3v/2A source will not give 2A to the TP. The device relies on switch signaling on the data lines which aknowledges that it is connected to the correct (ie HP barrel) charger and this allows the full charge rate to be applied.
In all other cases the charger only gives a low level trickle charge with the resulting longer charge times.
LiPo batteries and their charging profiles are very efficient and are perfectly capable of handling higher charging currents without detriment.
If they become very drained these higher currents are required to start the charge cycle whereas lower power chargers would not.
This thread is not about charge current or cycles, not sure why you haven't gotten a real answer yet, so I decided to register to give you one.
Even if you had the schematics and a source for the components, winding the coil for the inductive charging would be your biggest issue. At best it probably wouldn't be efficient enough to be worth it and it would likely take a long time to charge if it did at all. All the parts and work it would take for a kind of crappy result wouldn't be as good as just spending the $50 or whatever.
That's the negative side though, so don't get me wrong. If I could I'd totally be building one myself as well. I wish more people were into DIY stuff like this. I also really like the idea of building it into a desk and you may be able to do that with an official Touchstone charger.

While the OP was not about charge current or cycles I do sincerely hope that you understand the value of correcting misinformation and wrong assertions about any aspect that may raise it's related head in these threads.
To jump into a thread and the forum with such a comment is perhaps an indication of the levels of accepable politeness at large in the world today.
But I for one don't take too kindly to it.
But then us 'older' members may be a little too sensitive.
Any impropriety and the mods will deal with it!
I just got an universal charger for phones and I have a question regarding to it.
Since the original charger's output current is 1A, the one I got has 1.5A. Will it charge my phone without harming it?
I was told that these phones regulate the charger's output, so I shouldn't worry, but I'm looking for an expert's opinion on this before I try to charge it.
Thank you for your answer in advance.
Nope. The voltage is fixed, in fact, higher A(ampere) actually speeds up charging but depending on age of device in some very minor factor. From PC to Wall Charger to Car Charger to Power Banks, they might differ but they are mostly safe(mostly because some China Brands really messes up your battery somehow somewhat), they might not blow up your device, the most harm done should be deteriorating the battery life.
*ps:I was learning vocab so I dont really know if its the right use for the word deteriorating, I did mean to say weaken or worsen Cheers

I just bought a Anker 24W / 4.8A Dual-Port Car Charger. I bought this to replace a cheap $2 charger that I did not want to use on my nexus 5
I just tested the anker charger and it puts out 5.24v-5.29v. I know that does not sound like much but all my other chargers AC wallwarts, and even the cheap $2 car charger all put out 4.95v-5.02v.
Should I go a head and use this anker car charger or should I return it? Thanks.
That's just how much the charge puts out. The phone may not accept that much input.

Typically there is a boost/buck or other relatively efficient voltage regulator in the phones that manages the battery charging, so the 5% "over-voltage" that you are seeing shouldn't be an issue.
I'm guessing you measured that with no load -- most wall-warts run a little high without load, and then a little low at full load, so they can claim good regulation (+/-5%, for example) and a high current capacity. The change is due to internal resistance of the supply, something that you can compensate for, but can't ever get rid of.

I just did another test. This time with my phone almost at 95% full. I got 5.33v while sucking down 332mha.
Im sending it back. I tested every charger brick and several other devices in my home. nothing came even remotely close to 5.3v
USB specs are 5.0v +-0.25% so I should see no more then 5.25v.
I just wish to start this off by saying l am speaking ENTIRELY from MY POV and this is a SUBJECTIVE statement although I'm also Interested in other peoples Views and Ideas.
l see quite a lot hype about Wireless charging and whether the latest Android phone can or can't support it but is it really necessary ?! To me the argument that it Makes charging easy is fairly weak, l mean is it really that hard to plug a cable in ?! Is the current crop of chargers able to Match the same charging speed as Wall mounted chargers. Is the QI charger (it's the only Wireless charger I'm familiar with) able to match my USB 3.0 charger for my NOTE 3 ?!
My argument is instead of OEMs playing the numbers game in regards to Screen size, megapixel count and overall device dimension, how about they Focus more into their batteries. If all the major OEMs focused on their battery life of their phones, I liked to think we could see Some drastic Improvements.
What do you guys think ?!

I agree with you. I'd rather have 24+ hours on my phone's battery life rather than "wireless charging". IMHO it's not that hard to plug in a cable.

I'm looking for a Car charger that can fast charge the V10 and also had a 1 amp output. Has anyone seen anything like this? All the dual car chargers I have seen that offer QC 2.0 have a second port that is 2 amps. I want to charge my phone and power my electronic cigarette that gets hot when using a 2 amp output.
Thanks
Get this one. Very good. Quick charge 2.0 on one then the other slot provides 2.4amp output for universal any device and even tablet could charge off it as well.

Reason why I posted it, having read very well the op, I was having same issue and got this one which surprisingly works in my car.
I have the same one and it works without any problems. Perhaps you (OP) could reply in a better way instead of being snippy, he really did give you a good suggestion of what to get.

I'm sure it does work great, but i posted because I have a specific need and was hoping someone might know of a charger that could fill that need.
You won't find one. If it has QC , it will output more then 1a.

Look at Anker products, I have their "smart" charger. It adjusts to what is needed and supports quick change.
Regardless of smart or not, the device requiring the power will dictate how much amperage it draws unless charger or device is faulty up to the maximum available via the charger. Perhaps your ecig is very basic and is really meant to be used with a pc usb that doesn't supply more than 500mA and doesn't have the ic circuitry to cut and control it's own intake..
Like it has been mentioned for a charger to supply qc 2.0 it has to be rated at 1.8mA minimum, so most will be 2mA~
I spend a lot of time looking at chargers and havent seen any single that meets your requirements. I'd suggest getting a socket splitter and using two small chargers. One older 500-900mA and another qc 2.0.
get this one... 2.1 and 1A ports..
I wouldn't recommend anything but the cars port for the cig lighter.
Reason is, anything else that you plug that lighter into will be made partially out of plastic and will more than likely melt as the lighter heats up.
OP needs a lower output ( 1 Amp-500mA) to charge an electronic cigarette/vape mod and is not using the actual cigarette lighter. Honestly I would just advise that you remove the battery from your mod to charge because typically when mods fail it is either because a battery is being over-discharged (user error or mechanical short) or the IC circuitry fails causing the battery to vent. Charging your IMR batts in a dedicated charger tends to promote better daily use and overall extended life cycle. If you are still limited to keeping the battery installed in your mod while charging, is QC absolutely necessary? I personally have not ran into an issue topping off using a standard charger while driving.
EDIT: I thought the flux capacitor was a joke but looked it up and it actually fits your needs..
¯\_(ツ)_/¯
