I tried to charge my A700 with a HTC USB charger, but it didn't work. Can anybody confirm that the A700 only can be charged with the original Charger and not with any micro USB cable?

I tried several ones and none worked.
Thanks for confirming, that's really bad news.

But this was well known befor the device was available. This is necessary because of the huge power pack.
The original charger can provide 12V and 1,5 A. The USB specification is only 5V and 500 mA.
Did you try to charge the HTC with the acer charger ? you cannont plug it ! they added a pin
Out of couriosity,
in this preview they tell us it would charge on USB???

Not good News at all, im lucky i did not preordered this device, its a no go for me...
Can anyone try to charge over USB while the device is turned off, maybe this works?

No, it doesn't take any power from regular USB pins.
One has the choice: big power pack or loading by USB. I prefer the running time of this device.
Edit: Loading via USB would take over 24 houres for sure.
Now I found also 12V/1.5A on the right side of the housing of the A700. OK so USB is not for charging.
Did someone already find a car charger I couldn'd find at Amazon. (or should we discuss that in the other thread?)

Not yet, I think third party suppliers just need a bit more time.
I have a different experience to your's.
I've tested USB charging with two different USB-chargers. One from Nokia (5V, 1200mA) and one from Samsung (genuine SGS2 charger). Both charge the A700 in stand by mode with about 4% per hour and up to 100% battery capacity. The android battery info does not say "charging" but it does!
When the A700 is switched on my 5V chargers are to weak to charge it.

Confirmed
I charged my A700 with my HTC USB charger (HTC TC E250) in standby mode this night. It charged from 23% to 64% in about 10 hours. There was nothing at the A700 that showed it is charging.
To be honest, 4% per hour is "nearly not charging".

This is known as trickle charge. The device might charge if the micro USB provides enought mili amps AND the device does not need much power when connected (i.e. screen off).
I really doubt that the device will charge on USB when the screen is on, but on the other hand the device will definitly discharge slower when connected to USB.
I have a small calculation to explain things:
The original charger operates with 12V at 1.5 Amps = 18 Watts (which is not USB compatible so they hat to change the jack to ensure it will not be pluged in to a normal USB device and damage it)
If you would like to have the same Power over USB with its 5V max voltage you would need at least 3,6 Amps. Now that is far to much for those little pins on the micro USB jack and the currency would damage the pins when pluggin in and out.
USB standard specification normally is 500mA = 0,5 Amps ( -> 2,5 Watts in comparison with 3,6 Amps 18Watts)
So I think Acer has done a quite nice compromise.
Hope that clarifies matters a bit.

On the A510, when charging the battery via USB, the icon does not indicate it.
That must be the same on the A700.

Since USB 2.0 version :
"Several changes and increasing limits including allowing 1.5A on charging ports for unconfigured devices, allowing High Speed communication while having a current up to 1.5A and allowing a maximum current of 5A"
Source : wikipedia.org
Fortunately we are not limited to 500mAh, otherwise we could not quickly recharge our current smartphones .
There are some USB/AC adapters available that put out 2A of juice instead of the typical 1A. For those in the US, check out www.monoprice.com -> they're my go-to source for inexpensive spare cables & such.
It seems that finding a cheaper charger for the A700 isn't a simple task. I had to wade through a lot of cross references with some unintentioned misinformation. First thing was the model number. It's the A510 that is most like the A700 not the A500. Though the A500 does share some similarities it's not the closest match.
When I look for any type of charger, I make sure that the output voltage is correct and the amperage requirements are correct. Looking at the A700's charger, the manufacturer managed to squeeze a lot of info onto it. Amperage is what I always try to find. That is the total amount of current it can handle and deliver to the device connected to it. The A700's charger can handle 1.5 amps. So, the A700 sucks up a quantity of 1.5 amperes of electrons in order for the battery to fill up to it's capacity. That is the load the tablet's battery presents to the charger. Make sure that the charger bought for the A700/A510 can handle at least 1.5 amperes or the wall wart will be OVERLOADED. This is where the charger begins to overheat, smoking warning signals may start coming from the plug and your're asked for a donation for the local voluteer fire department. Besides the voltage which is 12 volts dc, load current requirement is the most important value I make sure is correct for saftey's sake. It is alright to get a charger that has a higher amperage rating but the voltage must be the same, 12vdc for the A700. It just means the charger can handle a larger load.
The only adapter I could find was the original Acer product, mainly because of the unique USB dual purpose connector interface. There is a little diagram of the pinout for the plug on the charger. Using a magnifing glass, I could barely make out the pins the +/-12vdc are attached. Pin P1 is +12vdc and pin P12 is -12vdc. It looks almost beyond a humans capabilities to make or solder together a short plug interface conversion cable in order to use other 12vdc/1.5 A chargers.
I've read in the forums some uncertainty about the proper specs for a replacement charger for the A700, that's why I wrote this post. Maybe , this will help clearup some of the confusion and not add to it. I've also noted a lot of chatter about using a USB cable with the micro USB plug to charge the A700 tablet. Apparently, USB charging can be acheived but it is very slow ( 24 hours or more ) and the amber/white power LED does not indicate the tablet is charging or has finished charging.
If anyone has more info about the A700 charger please reply or post....
Thanks All...
Hi All!
I know that it could be difficult for you to check this Polish site but you can find there a charger that I am going to buy. It has some changeble plugs - also micro usb.
link:
tridex.pl/ramka4.php?menu=towar1&symbol=9396
I think all what you have to do is to look for this kind of a charger - MW3R15GS, btw you can see this name on the original one...
Best regards
Gregork
Acer A701
Save your money and your A701. This thing has only a standard micro-usb plug-in. Check the connector of your Acer charger ... look really close and for better comparison hold a micro-usb-connector from a standard cable next to it. The connector from Acer is longer .. why? because the first row of pins that you can see are not the same ones that fit in a micro-usb-jack. Look deeper into the connector from Acer and you will see a second row of pins.
So if you use this charger with the adapter from that site and set a higer voltage you might fry the usb from your tablet. Sorry to disapoint you but better now than later with a broken tablet.
Hello,
my battery charger stopped working and i need a new one. I read a few review and i'm a bit confuesd, not every chargers with the capability to deliver 1000mAh works with every device. So which one oft them works with the desire s and delivers 1000mAh and not just 500mAh?
just buy a oem wall charger ,, easily found on ebay and also cheap
does it has any difference between 1000 and 500mah chargers? now i'm using original liveview charger with 500mah on it but also have 1A iPhone charger.

Double that. Overheating can be only caused by the phone itself, or a defected battery (means it is near death, but for serius heating, you will notice like 1hrs of battery life for the phone).
On another note for the topic. I use 3 type of chargers for my phones:
At home my ASUS tab's one (which is rated 5V 1A at the standard USB, plus the extra for the dock, but it is ASUS specific), at work an old ZTE "dumbphone" charger (which is rated 5V 0.75A, and is a high frequency switching type, so really energy-efficient) and for any other my old SE X8's one, which is 5V 650mA (which is also switching type). Also dedicated charger cables, 1 nokia, 1 SE, 1 HTC and 1 ZTE at my car.
The phone's original 5V 1A is NRFB at the box of the phone, but I have a security backup Samsung charger (rated 5V 500mA and pass-trough type, so not really efficient, but stable) which works just fine. The S is not capable (or not enabled just yet) of fast charge mode AFAIK so no really chance for 500mA or more when charging (even when GPS and 3G on, and screen on max, which is aroung 430mA when I last measued it with a service cable).

yeah i can confirm it was the 2 year old htc battery
i am now using 2 anker 1600mah batterys and they last a LOT longer + come with an enternal charger so i always have one charged, it also charges the old htc battery too externally so i can now use 3 battieries mwahahahaa
note i did have to delete battery stats in cwm to recalibrate
Hello,
I was wondering, can I use the old charging cables from an LG Optimus Black and Samsung Galaxy S2 to charge the Nexus 5?
I also have a car USB adapter and a spare USB-to-microUSB cable.
Can I use all sort of plugs/cables that match the connector size, or should I pay attention to any details regarding current/voltage?
I noticed the original PS for the Nexus 5 supplies more power than all others I have, but that may just mean that it would charge slower, which to me is not an issue.
I not only want to avoid doing any damage, but also of course shorten the battery life!!
Thanks

Any Micro USB cable will work with the phone and you shouldn't have a problem with voltage or anything like that dont worry bro
I notice nexus 5 is very picky on your USB cable if u want a fast charge. So of notice it going pretty slow. Try another cable
Sent from my Nexus 5 using xda app-developers app
Any USB charger should be 5V. You could in theory get a cheap charger that is off by some amount, but even then it would have to be significantly higher (5.5V+) to cause damage.
Current just affects the charging speed. A 0.5A charger is just going to charge your phone slowly. Your phone won't draw more than 1.2A though, so a 2A charger would be fine.
I was wondering about the USB cable as well, if I recall correctly, didn't the Nexus 4 had one less pin in the micro usb cable and Google only recommended using their USB cables?
I have a tone of Samsung micro USB cables from my numerous E4GT that I went through. I also noticed that the N5 charger brick says 1.2 on it so it's not your standard 1 amp charging brick.

Unfortunately the N5 seems to report most chargers as USB Mode chargers rather than AC Mode. I've noticed this with my Battery Packs, multiple car chargers, as well as multiple home chargers that are cheap. The N4 reports them all as AC chargers, but the N5 reports them as USB Chargers

Silly question, but how do you tell the difference on your N5 from USB charge vs AC charge?
Not a silly question at all. Go into settings and check "Battery" when you get in there, It shows you xx% Charging ("Whatever you are charging through")

I've not used the bundled charger, just re-using my old one that is an AC Adapter with a USB cable. I'll check tonight to see if it's charging in USB or AC after all.
Hi,
Wanted your thoughts and opinions on charging speeds. I've never actually timed how long it takes to charge. i leave it overnight and it's ready when i wake up.
When i plug the phone into the charger, it flashes up slow charging for 2 seconds then disappears. which got me wondering how much it's actually using.
i used to use Current Widget app on my Samsung S3 which told me exactly how much current the phone was taking from the charger. typically it was 1A via AC/mains and 499mA from a PC. Plugged in to AC, I could play a power hungry game and it would still charge the phone at a good rate.
The LG kernel doesn't like these apps - the mA value is all over the place but it's typically <500mA displayed.
I could buy a USB ammeter to work out how much the USB charger is supplying but do you have any other methods of finding out? Do you know what your phone uses?
at home, i use a Xtrememac dual USB charger, 2x 2.1A output with a shielded 3M USB cable. for those wondering, it's the same regardless what cable i use. Have also tried with generic usb chargers, iPad chargers and official and OEM cables from LG and various other manufacturers. Have also used a data-shorted USB cable from PC which is the same result.
I haven't tried the LG charger yet (mainly as it's a 2 flat-pin plug and i don't know where i put the box) but i think i recall it being a 1.8A charger.
I use an application called "charger report" which can display current consumption and Xtar "USB detector" device. They both show the same numbers. But Xtar USB detector can detect voltage of a charger. The charging current of LG g pro 2 is 1.4-1.5A when the smartphone is not used and higher when I use it. Using USB detector I found out that this smartphone can charge with maximum current a charger can give only if the charger's voltage is 5.3v. So it chargers at full speed with original charger and two other chargers I have: a charger from my Lenovo s6000 (2A 5.4V) and from my Asus t100 (2A 5.3V).
i tried that app too and got the same results as with Current Widget.
i'll buy a "usb detector". thanks.
I forgot to mention that it take approximately two hours for charging indicator to reach 100% when the smartphone reports that it fully charged. And it's necessary to left it connected to a charger for ten to twenty minutes to be really fully charged. Otherwise charging indicator will soon drop to 90%. One can tell if a smartphone is still charging by touching a charger or by looking at current consumption: a charger would be warm and current would be higher than 200mA.
Is the GP2 Quick Charge (1 or 2) enabled? I can't read anything about it other than it's in Snapdragon chipsets. Not sure if it can be disabled or not.

Hey ray-lee!
I just bought this phone and as it seems it could get someday similar problems as my former phone the Galaxy Note 2.
That phone has had problems with charger and cable also. I had to buy another set of charger and cable since the original ones gave up a few months after i purchased the phone (it was used). The cable managed only 500mA wich is very slow for a battery that strong. One night was once not enough to charge my phone from 30% to 100%. As it seems it is problematic to manufacture cables, that can hold up and continually grant the 1,8 A that would charge our device in just 2 hours. I read somewhere that the G Pro 2 is one of 5 devices that has blazing fast speeds on charging the battery. If you handle the cables with caution hopefully you will not encounter problems. If so my guess is, that you will have a hard time in finding a cable that can hold up. Sadly the stock cables are always more expensive. I do not get it, why companies dont build travel adapters that only charge ur phones built solid with sturdy cables to ensure the transmission of high currents. That way with charger + usb cable is just stupid, even when tis is an all in one solution.
I like this phone very much and i hope, that the cables will not be that sloppy as the cables that Samsung had/ still has. With Current Widget i get readings around 1500 mA (1,5 A) when connected to the stock charger. And yes the LG Charger is an 1,8 A one. I have also flat pins, but received an adapter to be able to connect it in Hugary.
Just sharing thoughts here, that will maybe helpful to someone...

i "think" as long as device has snapdragon it is Quick Charge enabled
I use the "Charging Report" app on my phone, and it reports proper values.
(Around 1500mAh with the LG charger, and around 1600mAh with the 2.0A Samsung charger.)
If your phone is charging slowly, check the CABLE. Cable can broke too.
(Many people complain about their Samsung charging cables, because they just stop delivering power after a while and just charge the device slowly.)

Hello
I need to replace the usb cable that connects to the original charger that comes along with the phone.
There are cables out there that are sold as original Samsung cables but don't fast charge the phone in 78 minutes from 0% to 100% even if they are connected to the original charger.
So is there a cable that truly fast charges the phone exactly like the original in 78 minutes?
The cable has nothing to do with it. Use a regular functioning USB cable with a Quick Charge 3.0 charger (such as the Samsung charger with the lightning bolt on it, or the Anker Quick Charge series) and the phone negotiates with the charger. The cable is just a medium. I prefer the Anker PowerLine+ cables for their durability; the stock Samsung cables are fragile.

Τhanks a lot socal87. I was thinking the same thing as you but i got worried from negatives reviews in amazon ( saying that the cable they bought wasn't fast charging the phone).
Also in another well known forum, there were comments like the following :
"Samsung plays with the extra pins on the microUSB connector to tell the phone different things - like USB/AC charge, or fast/normal charge."
"My troubleshooting with 7 different cables showed me that the the very new Samsung charger cables that came with non-fast-charging phones did not fast charge when connected to the fast charger adapter portion. It appears that the cable does in fact matter. I tried many combinations of cables and adapters during my testing."
I will buy an Anker cable as you suggested. In another forum i read than indeed the Anker cables do the job right with fast charging. Thanks again.
Of course the cable has to do with the charging of the phone, try charging with a cheap $2 cable from eBay and try yourself.
Best cables (that i use) are from Monoprice, get their Ferrite core one, best cable out there, charges my phone to 90% in around 70-80 minutes with normal charging (no Fast Charging)
Try any original cable from HTC Nokia Samsung Motorola you can find one in repair place ask him for used original one or new...
Τhank you all for your suggestions. I have already ordered an Anker powerline cable from Amazon and i face any problem i ll buy one of those you suggested.
Blitzwolf does be more better distance charge of 1m at Maximum average 2,1-2,4A of 9V/2A or 5V/3A
You can find Samsung original cable in any official service. I have paid 5$ for a 2m long cable and it takes about 1.h20m to charge from 1%
