[Q] got a generic charger....it says-5v 500mah,original is 5v 1a(amper)is this ok?

it says- output :5v 500mah
the original says-output:5v 1a(amper i guess)
will this screw up the battery?

chances are no, considering it is half what htc recommends you charge it with, either it will charge it very slowly (half the current of the original) or the voltage wont provide enough to kick the phone into charging mode and nothing will happen (i.e. the charger "wont work")

Thanks for the help

It'll work, but as panyan said, it'll recharge much more inefficiently than with a 1 amp charger.

Actually... It will charge the phone exactly as charging via USB, as USB is limited to 0.5A.

Yep, it will charge your phone just fine @ USB charging speed, I have a similar charger.

And some of you forgot to mention that the phone will struggle when for example you will play games or use gps. Charge will be insufficient and instead charging it will slowly discharge while using it.

Well yes and no, in normal usage it will charge phone, but when you use your phone the way that you would drain the batty in two hours, then it will discharge.

Hey... Yeah if the charger is a car charger then it may not charge fast enough if using GPS software which can drain the battery fast. 1Amp reccomended for faster charging... other than that should charge fine but just slow like USB charging (which has a max of 500mA).
One question guys... I bought a car charger from ebay listed as for HTC phones. It looks like a cheap knock off product with a glowing blue HTC logo when used in the car. The device is rated at 2Amps. Now from what little I know about electronics I've been told that AC/DC Plug packs with more Amps are ok and the device just only uses what it needs. I'm not however familiar whith battery charing when you have a higher rated Amps charger... Would the battery on the phone just be greedy and "ask" for the full 2Amps? Would this then put strain or be dangerous by charging the phone too quickly?
Secondly while we are on the topic of electronics... I'm trying out a super cheap ebay battery supposedly rated at 1600mAH (I know these rating are usually fake). I've noticed the HTC battery is around 4.17V when fully charged. This battery charged up to 4.2V fully charged... Is that dangerous for the device?

2 amp is better, correct me if i am wrong. So the output is 5V and 2A, is that mean the power is 10W every hour ?

2 A charging current (if the phone takes in that much) will damage the battery in a long term use.

It is incredibly unlikely that the phone will discharge the battery faster than it charges unless you're doing something very wrong, e.g. Running a console emulator while downloading a large file over HSDPA with WiFi enabled (but not connected) and using GPS navigation with screen brightness at maximum!
Screen and background services take approx 150mAh, and I doubt radio will take much more than that combined. That puts drain 200mAh less than USB charging, 700mAh less than direct charging.
FYI: There's a spec for USB charging of mobile phones from supported USB ports which can pull up to 1500mA.

Hmm... not sure for Desire HD I haven't tested GPS with SatNav software using current widget... I do know that I'm pulling well over 200mA just with basic use at home with Wi-Fi on and GPS & Bluetooth off and I kill all backround apps. I do know that I've been in the car and seen TomTom app on my friend's jailbroken iPhone 3G (or 3Gs) and with the GPS on and not doing anything intensive... we were actually travelling down a long straight highway, the phone was chewing more battery than the car charger could charge, so he switched off GPS.
Ah also guys no need to worry about the 2Amp charger... It sh*t itself on the 3rd car use and no longer works at all. Junk! I also noticed on the 2nd car trip that opening Android SpareParts the charge is displayed as USB Charging not AC Charging so yeah I believe that the car charger was only a standard USB (max 500mA) power output and not 1Amp let alone 2Amps. Annoying how false advertising or labelling is part and parcel with cheap Chinese products.I was meaning to test the charger's output with Current Widget (which is what I'll do for my next car charger) but the charger crapped out and was useless before I got a chance.
One thing I did notice from looking at a log using Current Widget while charging my phone on the A/C charger in standby, the charge tapers off the power output the more the battery is charged. To get an accurate idea of if the car charger is going to be outputting 1Amp I'd be sure the phone battery is down to 40% (or in the 40s) then with all other stuff switched off I'd run a log on Current Widget and turn the screen off for a few minutes. You should have a reading of around +700 to +800mA if the car charger is rated at 1Amp.
Be wary of the cheap Asian knock of car chargers with the coil spring cord and the HTC logo that lights up blue.... Not worth the 3 or 4 bucks they sell on ebay for.

There's commonly those double USB cables for laptop hard drives so yeah I can see that if the USB ports are actually giving you the full rated maximum of 500mA you can get 1Amp output with this kind of cable but 1500mA?!? The only way I'd see possible for this is either you have a tripple USB cable connected to 3USB ports that are all outputting the full 500mA (and that's if a triple cable even exists or lets say you solder another one onto a double cable) or you have a USB AC/DC charger or some other USB port/hub you've rigged up which provides more than the USB standards of max 500mA per port. How else is this possible?!? Has the max power output of 500mA changed since USB 2.0 standards?

yeah there are usb 2.0 ports with more than 500mA power supply.
some companys give some extra juice to their (or often only one) usb ports.
for example: i've got an Dell Studio XPS 16 Notebook here. it has 3 usb ports, 2 with normal 500mA supply and one with 1A (for charging your phone, etc).

USB charger

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?

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.

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.

[Q] Nexus 5 alternative chargers?

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

[Q] Need someone with hp touchpad charger to confirm

So, the charger for my old touchpad has the longest cord, and twist to lock is great..
But I've noticed that my phones all charge ridiculously fast on that charger (40 minutes from dead to 100% in most cases) and I'm wondering if maybe it's being detected as a quick charge plug? On stock, I didn't get the slow charging notification, and I don't get it on Viper or Bad Boyz either.
Does anyone know what it takes to NOT trigger the notification? Is it a certain pin out? I'd assume not, since you can use any cable with the Qualcomm wall wart.. Is it a specific voltage? Amperage? I know this charger is 2A, 3.5V and from what I can find on the Qualcomm specs is that a charger needs to be capable of 1.5A, 5V for quick charge certification, which puts my charger still 1.5V shy.
So why does my m9 charge to full in about 55 minutes, vs a few hours on stock, and NOT trigger slow charge notification when it's (afaik) not quick charge?
Can someone else with a stock touchpad charger that gets the slow charge notification test this out for me? If it turns out this is basically an uncertified quick charger purely by virtue of coming out before QC, that would give us an option for QC on the cheap!

So far the best I can find is that the reason this charger does so well is because the touchpad is a power hungry beast and needs a beefy charger, more so than regular tablets. I guess that explains it. It's putting out more than a phone charger usually would, which is why it isn't triggering the slow charging prompt

My daughter "inherited" my touchpad, but I believe its charger was 2 amps
Sent from Tapatalk on either my HTC One M9 or Tab4 10.1, it kinda depends

My touchpads wall wart puts out 5.1 volts and 2.1 amps, with it's quality cable. It is the fastest charger I have out of the dozens I have tried. Most put out less current/amps and that is why it can charge so fast my comparison. But know that one bad USB cable can make the fastest charger slow. I used the galaxy charging app to test my cables on it, and found some of my USB cables would only do 400ma no matter which charger they were in, so I threw out or marked all those so I wouldn't use them for fast charges.

Why does LG G FLEX 2 LOSE CHARGING while playing games and charging at the same time?

My g flex 2 H959 cant charge while playing games, for example like temple run or even old nokia games like snakes 97?! it will actually drain the battery while charging if i use a SAMSUNG charger and it gains around 1 percent per 5 minutes if i use my LG FAST CHARGING charger, so the question is why lose so much when you play such light games.

on topic: in Games the GFlex2 use the whole Power of the Snapdragon 810 and maybe the GFlex2 is not optimized for playing Games, can be, but you can help your battery:
turn down the brightness, root your phone and use Greenify and disable or delete bloatware and useless google stuff, force your SD 810 to a lower frequency and so on

It's your usb cable!
The cable quality is very important. Even if you have a good 5V charger, it's useless with a slim and long cable.
The more resistance (ohm) there is on your cable, the more intensity you will lose (A). And the resistance goes by two factor, cable thickness (AWG in USA and mm² elsewhere) and cable lenght. The thinner and the more lenghtful is the cable, the less Amp will go thru.
I have a usb voltmeter and ampmeter so I can give a value on each scenario.
I have a usb charger that can deliver 2.1A and 5V. With a normal cable that was bundled with blackberry (I got them at work) I get 690mA. Cable is 1.2m long and 28AWG is marked on the cable.
With the same charger and a 50cm long cable and 28/22AWG gauge (I suppose it's 28AWG for the data cable and 22AWG for the charging cable), I get 1.29A
With a 3m cable (yes it's long but I have a purpose for it) of unknown gauge, I get 250mA, sometime 300mA maximum. And this intensity it's just a little more than 1W. Even overnight I lose battery percentage.
But with the LG Fast Charger it's all different. It's not labeled Qualcomm Quick Charge 2.0 because it don't deliver 12V. The LG charger deliver 5V and 9V while Qualcomm spec for QC2.0 must be with 12V too. Anyway lets say it's a quick charge 2.0 charger because it act like one.
With the LG charger, with the 3m cable, I have 8.2V and 1.2A which is nearly 10W, more than enough to play and charge at the same time.
I can explain why the 9V tension help with the high resistance of the cable but to make it short it's the same as the big high tension cable in country side, the high voltage help for the long distance even if there is very big cable.
The usb cable provided with the Flex 2 is very good, it's 20AWG on the charging pair. But if you can find shorter cable it's even better (Western Digital cable is very good but to find one of their device bundled with a short and tick WD cable that is not mini usb and not usb 3.0 is very hard).
If you want the fastest charging speed you have to buy a QC2.0 certified charger and a 22AWG or 20AWG short cable. For daily charging I recommand using your old 5V charger (your samsung one).

Thank you so much for this answer bro

What you describe is different from the original post.
First you said that with a 5V charger (samsung) you lose percentage while playing but it was ok with the LG 9V charger.
then you say while answering to me that even with the LG charger you lose percentage but even if your cable is crap, the LG Fast Charger deliver enough power for any situation.
So you really lose percentage while playing with the LG Fast Charger?
And please, no proselytism.

nope but with the lg charger it charges at around 5-8 mins for 1 percents, excuse me but that is wrong , it shouldnt

you meant it's not fast enough or too fast? I don't get your point.
If it's not fast enough, then do not use the phone while it charge or get a Quick Charge 2.0 charger that can do 12V.
If it's too fast, roll back to a 5V charger.

I was always under the impression that it is really bad for the battery to use the phone while it's charging. Perhaps just plug it in and let it charge while not using it is the best solution to charge faster.

I tried a Quick Charge 2.0 charger. The one supplied with our Flex 2 is not a QC 2.0 because it's only 5V and 9V. It still use QC 2.0 spec as at first it's 5V and when it identify the device it deliver 9V but it's not QC 2.0 certified as it don't deliver 12V.
So with a QC 2.0 charger, it deliver 9V too to the Flex 2. That mean that even if the S810 is capable of 12V charging, it's up to manufacturer to specify how it works. It won't charge at 12V.
I don't have another recent snapdragon to test the 12V.

Same!!!
I know its not good for batteries to be used while charging, but for example, i also have a Moto G and its okey playing while its connected to an outlet.
But with my Flex 2 its different, it charges incredibly slow, and worse... it gets HOT! REALLY HOT!
I'm trying now the thermal adjustments suggested by probaina.
Hope it works.
I'm going crazy...

What? My ATT version charges incredibly FAST! Sometimes it gets warm, but nothing I would be concerned about and it's even less after 5.1.1 update. Heck, my M8 gets just as warm if not more.

LMELME83 like OP you have to clarify things, is it slow to charge with a normal 5V charger (like the charger from your old phone) or is it also slow to charge with the charger provided, the LG Fast Charger?
For the 5V charger, the usb cable make all the difference.
For the LG Fast charger or a Qualcomm Quick Charge 2.0 charger, it's all about if the charger recognize your phone and there is no way to tell it on the charger or the phone. You have to use a usb voltmeter. I can recommand one that can take 12V.
Anyway it's normal that the LG G Flex 2 get warmer than the Motorolla Moto G (regardless of the generation because there is 3 or 4 different moto G). Any entry level phone will be colder, like a Core i3 will be colder than a Core i7 even if no one is crazy enough to use a core i7 with the stock heatspread and fan.
