5v 1000mA charger

Would it be safe to charge the batter at 1000mA compared to the stock 700mA the charger provides?

yes, i do it all the time

I use the charger from the Galaxy Tab all the time, it's rated at 2A and the S does see it as a proper charger. I've not checked, but I also think it charges the phone faster than the stock charger.

yes it does
the higher the Amp, the faster it charges
however this is not compatible with all phones
the SGS is a good phone, my Motorola will not charge if you exceed or you are under the original charger spec (which is totally stupid) but i understand it is to protect the phone, from over heating
SNS also accepts higher output chargers

So can I use this ?
actually it is ipad charger, 5.1V 2.1A output.
On the phnoe label it is printed max~1000mA
but this is 2.1A.....(2100mA)
it seems too high...

The battery might heat up to a high temp and if done regularly it could very well shorten the life span significantly.. the stock 700mA charger makes the battery warm, Im guessing that 2100mA will make it very hot, but you can try for like 30mins of charging see if thats the case.. if you can just say its warm then I would presume its safe.
700 to 1000mA charging has very little difference on the warmth that i feel from the battery.

If you have the International Galaxy S GT-I9000 it won't charge any faster than about 450mA regardless of the charger rating (from my tests). You can get a higher-capacity charger but it won't make any difference and is quite safe so long as the voltage is correct.

The International Galaxy S I have comes with a 700mA charger though, there is a noticeable charge difference between a USB port (500mA) vs the stock charger (700mA) and my 1000mA charger

If 2100mA is also supported, the charge time will become in just 43min (in theory).
And if the charge circuit is safe enough, it will control the current to 700~1000mA, and it will drive below 200mA in the beginning of charge.
Just try plugged to my phone, it is charging as USB not AC,
so I think the currect will limit to 500mA.....
will try again later, my battery is still full now.

If theres a 500mA limit why do I get faster charging speeds with the wall charger compared to the USB ?

That's the question..
I'm using data cable, so the phone just detect plugged to USB i/o AC power.
maybe I need to use straight miniusb power cord.
Then it will really challenge the phone in 2.1A
On the other hand, IP4 & Ipad can draw 1A from computer USB, (need new motherboard)
what about Galaxy S !?
I will test it later.

If the charge time is less than one hour,
you are getting benefit of high current.

In relation to what you said that IP4 and IPxD can draw 1A, thats why I said the USB 2.0 spec is only 500mA so those devices cant draw more than 500mA on a USB port.

IP4 is USB2.0 Device,
plug into high power USB port (that is USB3.0 port)
USB2.0 IP4 can draw over 500mA
I know what you mean, if the source is USB2.0 of course you can't draw higher than 500mA.
My point is, if the device can draw higher than 500mA, just like the usb2.0 IP4,
and if galaxy s can draw that high,
then we can get benefit from the high output usb ports and also that high output usb charger.

Hello everybody,
I want to share my experience.
So I have a Samsung galaxy S, and usually I charged it with the original charger (700mA).
I tried with a 1000mA one. The charger was really faster than with the original one. So I thought that if I buy the galaxy tab's charger (2000mA) it would be faster.
It's what I did. But the problem is that it's not faster with this one than with the 1000mA one.
I think the problem comes from the USB limit of charge (1000mA in a outlet, 500mA on a USB port from a computer).
But I have a problem with this... I mean, the galaxy tab is charged by an USB cable too, even if it's not the same plug out (I don't know the name of this plug out, I know on the galaxy S it's a micro-USB) on the cable, it's still an USB cable. So why this USB cable can give 2000mA while it uses an USB technology ?

it's definitely faster charging on a 1200 nokia charger..

I can't help myself and I must tell you guys something. The mA of a charger means how much current it can provide in 1 hour, imagine it like a pipe through which only a ammount of watter can pass. Now going back to the phone... We have a 1500mA batt which means that if we use a 25000mA charger it will only output 1500mA... So it is useless to use a more powerfull charger than 1500mA. I hope you understand what I said

That is a 1500mA*h* battery which means capacity and not current.

[Q] Voltage on unofficial micro USB charger

My GF ran over my mains charger cable with the vacum cleanerr at the weekend, so i ordered i new one from Ebay. Rather stupidly (as an "official" one would only be £1 more), i bought this unbranded one:
UK MAINS CHARGER FOR SAMSUNG i5700 i9000 GALAXY S on eBay (end time 02-Apr-11 14:51:41 BST)
When it arrived i noticed that the output is different: 5.5v 500ma as opposed to 5v 700ma from the one that came with the phone.
I know tha ampage will affect charging speed, but am concerned about the extra 0.5 voltage. Is this safe to use?

I'm curious about this too... I thought the "U" in USB meant Universal.
I just ordered 2 micro USB chargers from Ebay for my GF's Sony Vivaz Pro and my Captivate... neither work.
Her's doesn't recognize the charger at all... mine beeps and says "charging", but the battery level never goes up.
My chargers are 5v 500mA.
The chargers were listed as Blackberry chargers, but had a long list of compatible phones underneath (none matched our phones, to be fair.)
Now I'm afraid to buy any more generic chargers....

I don't know if the output voltage is part of the USB standard or not. I know that computers output 5v and it seems like a lot of phone chargers also do. However, i've seen some external battery chargers listed as compatible with the SGS listed as 5.2v, so maybe theres an accepted voltage range? Does anyone know for sure if a 5.5v is acceptable?
I'm not sure why the ones you have don't work as the specs seem right,possibly they are faulty?

Yeah, I'm not sure. I certainly thought so, even though it seemed pretty "unlucky" they both might be faulty.
I did ask the seller, and they claim they are NOT compatible with my phones, but I just don't get it. They're offering me a refund, but at $4 each it's hardly worth my time mailing them.
I found some forums online of a small handful of people like me with chargers that won't work. It seems people with this issue were using 500mA chargers, and anyone using a 700 or 1000 had no problems. This wasn't necessarily because all phones either require 500 or 1000.... Someone also said it's only very certain phones that are built this way. That they require newer, or more powerful chargers... but that it's not the case with all new phones/smartphones.
But there were others who said 500 should charge it, just more slowly.
I still think Micro usb is Micro usb, period. That's why the EU (and here) have been looking at making these chargers universal. I think I'll just try my luck again with another charger.

You could try this one, which claims to be (and looks like), an official SGS charger:
http://cgi.ebay.co.uk/Samsung-i9000...ories_MobilePhoneChargers&hash=item2c5b2d355a

5.5V is supported. I've tested a very wide range of chargers for my SGS and all worked.
The voltage range of these chargers is 4.8V - 5.6V and all worked just fine.

I've actually got an original Nokia USB charger which is declared at 5.0v/550mA and it works like a charm...
Model is AC-6E:

Well finally decided to give the ebay charger a go. Plugged it in, a green light lit up and plugged the phone in. The phone didn't recognise the charger, no indication the the notification bar that the battery was charging. Unplugged it and and tried again, and now the light on the charger doesn't even come on! Won't be using it again.

Another question on the topic : Is it save to use charger with higher Amperage ?
I mean original samsung one is 0.7A, could something go wrong if I´ll use 1.0A charger? Thanks
EDIT : Answer no needed anymore - found it in another topic. It should be safe

I believe any microUSB charger will be safe. Ideally, you want the highest voltage and highest current possible.
I've heard that the phone will use the data lines to tell the USB charger what voltage to set. This ensures voltage compatibility. Then the phone itself regulates the current.. it will only draw as many amps as it needs. So if the PSU can handle 2A, your device may only draw 0.725a for example, but it's safe. You want a high current one to ensure the phone has all it can take.
BTW, I'm not an EE person, so double check what I said.

I fear it's not that simple, especially with dumb chargers that can't negotiate current using the USB protocol, and instead may short the data lines, in various ways, instead to tell the device what current to draw...
Sent from my GT-I9000 using xda premium

There's an explanation here of why different chargers do indeed make a difference:
http://en.wikipedia.org/wiki/Usb#Power
see in particular the note on the Battery Charger Spec.
In particular. my own testing shows I can go from 500ma to 700mA charging current simply by changing a small connector in line between the 7Ahr battery I'm using to charge the phone, and the phone. That's due to the nature of the short on the data pins.
There are proprietary tweaks to this mechanism; e.g. iPhones use voltage signalling between the two data lines and ground to indicate various things to the device.
All of this is only for "hosts", i.e. chargers etc, that don't implement the USB protocol and so can't engage in the normal current negotation that occurs when connecting e.g. the device to a PC.

Maybe because the current is higher. My battery voltage is arround 4200mV at 100% and 4100mV with USB
For the solar charger 5.8 is really high but the wall charger is ok

guys can anyone tell me what would be the reason that my Samsung j7 prime charger is giving me 4.63v instead of 5v .. the rating is 5v on the charger. is that possible the ic or some other thing is damaged? in that case what would be solution?

Not quite. It can't draw the current it needs if the charger is rated lower than what it needs. A 5v 500mA (0.5A) charger will take far too long to charge this phone or even not charge it at all if the phone is being used while connected to the charger.

Ye, this is the reason I actually asked, since I wanted to know what's the minimum mA.
Luckily, i recently found a white usb wall adapter and just checked and it is 1000mA(1A) so all good hehe :highfive:

According to Motorola Support anything between 500mA - 1.5A should be fine and higher values will be limited to 1.5A. I cant post links yet, but info was found on MotorolaSupport twitter.

I have been cross using my Nexus 7 (2012) and Samsung S4 with each other's charger all the time in the past, it didn't do any harm. Now I am using Nexus 7 charger to charge moto g

Any Motorola charger with the correct micro-USB tip will charge your Moto G. You will see the best results when the output of the charger is between 500 mA and 1.5 A. The higher the output, the faster your Moto G will charge.
If your charger output is higher, the MOTO G will automatically restrict the charging rate. If your charger is lower, it will simply take longer to reach a full charge.

According to Motorola, the Moto G will automatically restrict the charging rate to a maximum of 1500mA. Therefore, 2A chargers should only charge at 1500mA. This is within the allowable range listed on the Motorola support site for the Moto G. So, no direct damage to the phone circuitry or immediate damage to the battery should occur by using a higher amperage, faster 2A charger.
But, the latest official Motorola charger on the U.S. website is only 1200mA. Using a 2A charger to charge at the 1500mA maximum allowable rate may cause more long-term reduction in battery capacity than using the lower charging rate of 1200mA. See this other XDA post for my logic in coming to this conclusion ( http://forum.xda-developers.com/showthread.php?t=2564158 ).
UPDATE and CORRECTION:
I have more authoritative information directly from Battery University that changes the conclusion I draw above based on my effort to extrapolate from the Battery University website article.
The extrapolation I did in the post listed above was based on the additional loss of long-term battery capacity cited when going from a 1C to 2C charging rate. But according to direct communication from Battery University, when charging at a rate below .7C there should be no measurable improvement to long-term capacity by using slower charging rates. Charging above .7C would still be expected to add more stress to Lithium Ion Polymer batteries and likely add to long-term reduction of capacity.
So, what this means for the Moto G and Nexus 5 is that there should be no measurable difference between charging with 2A, 1.2A, 1A, or 850mA chargers as far as effect on long-term battery capacity goes. Both the Moto G and Nexus 5 are supposed to automatically restrict the charge rate at 1500mA even when using a faster charger, which is just at or below .7C for both phones. So, as long as the charger dependably keeps to 5V, a higher amperage 2A charger will be faster but pose no problem to long-term capacity.
----------------
Using the 850mA charger referenced above as shipping in Brazil should be fine to charge with in about 2-3 hours. The only issue is that the phone would need to be turned off during charging in order to not take too long -- which is a good practice anyway.

The original charger that came with my phone has: 550 mA.

550 mA charger is fine for Moto G, it will just take longer (like 3-4 hours). If your charging over night than it's not an issue. Just plug it in and leave it on over night. The Moto G will automatically stop charging when it is complete. Only advice I've seen, is that it is not good to leave a phone on the charger for long periods (e.g. over 24 hours).

Fast Chargers

The LG V10 does support Qualcomm 2.0 Fast Charging. Here are the models of Batteries, Car Chargers and Wall Chargers that I have tested and confirmed that work with the V10 . I will include some video reviews as well.
MOD Edit: Referral links not allowed and have been removed

So do you need a new charger that supports fast charging, and any micro USB cable will do?
Does the charger that comes with the phone support fast charge?

yes, the charger that comes with the V10 is a quick charge and most micro USB cables (should) work with the quick chargers.

The Samsung adaptive quick charger from the S6/Note 5 seems to be working well. Just an FYI if anyone has one laying around.

Tronsmart said:
Not all of the micro usb cable will support quick charge. you need the cable which support charging and data sync together.
The quick charge 2.0 technology need to transfer/communicate the signal from the charger to the smartphone. some cheap micro usb cable which just have the charging function won't work on qc2.0 chargers.
also the 20awg cable help to transfer high current, see the explanation from wiki:

Yes I am trying to look back at where I got my cable now. This is the heavier duty, longer cable I use. It says in the description a few different things that makes me think it is compatible. I guess I'll find out for sure when I get the device in my hands.
http://www.amazon.com/gp/product/B00OCDZQA0?psc=1&redirect=true&ref_=oh_aui_detailpage_o08_s00
Edit: I did find out that it does support quick charge, so I'm all good!
FYI I would reccommend this cable if you are looking for a longer cable that is heavy duty. I am sure most have used Anker products in the past, the quality is present in this product as well, I have had mine for close to a year with no issues.

I love Anker product, such high quality! The dual port car charger supplied 2 amps per port. The desk charger supplies 2amps per port over 5 ports and over the last year I've purchased 40+ usb cables in varying legnths. 10ft - 1ft. Connections are always snug and no wiggle on my phones. I keep giving these things away when a co worker needs a cable, they always notice that their device charges faster, especially if they no longer have the oem cable.

Quick Charge not compatible with charge-only cable
In order to prevent data theft I prefer to use a charge-only cable when plugging my phone into any port outside my home.
According to Qualcomm, Quick Charge 2.0 is designed to be connector-independent and is designed to minimize charging issues associated with long or thin cables, allowing for a superior charging experience, independent of cable type.
However, since the high-efficiency transfer of electricity requires the D+/D- data lines for effective handshaking and communication, it will not work with a charge-only cable.

I have to say the quick charge lg charger still takes twice as long as my note 4 edge to charge...

Other than stock cable, PNY cable works pretty well especially with Anker 8A intelligent charger.

I can say without a doubt charging with the Samsung quick charger from the S6/Note5 charges the V10 faster than the LG quick charger. Luckily I have several around the house.

I think that is due to the fact that the LG charges at 2.0 vs the Sammy.

something i found out bay accdent is it doesnt always fast charge. its not an option to turn it off but from what i can tell if your phone is to hot when pluged in it just does a normal charge. greatest thing ever
and i did try it on two chargers that have fast charge the one in the box and the note 4 charger but it didnt start the fast charge. once the phone was cool i actually unpluged to go somewhere came back ten minutes later pluged in and there it was fast chargeing.

In response to @clockcycle
It appears though it may charge faster than normal charging methods with screen on, that it almost quadrupled charging rate with screen off according to Ampere.
Take it for what it's worth, I am not sure how accurate it is, that second screenshot was taken just after turning the screen back on, where it proceeded to recalculate and then displayed around 700 again.

Awesome thanks for testing that, it seems to be just like the LG G4 but slightly higher (500 screen on, 2200 screen off). Ampere is a guestimate, but I use USB Doctor sleeves to verify. What charger did you use to test?
Edit: according to your screen shots, they were 2 mins apart, you went from 8% to 11%, gained 3%~

Same over here, can't get it over 5w.
Charging voltage has something to do with it, what's ur charging voltage?

Using a digital usb meter I noticed all PD chargers stay a 9V with 0.45A output. I tried a kernel on XDA that it's supposed to force fast charging but i didn't do anything.

I find it very weird nobody is talking about this on XDA, only a few threads on reddit.
If you are outside and you don't have your stock OP 65W charger with you you have a high possibility of not being able to charge at all since it can take 5 hours to a day a this speed. How is this even legal?

I may be a little confused here, but I get pretty dang close to 27W of charging power when using my USB C charging brick that came with my Samsung Galaxy Book 360. Franco kernel manager usually says I average around 25W charging power. I'm assuming the USB brick is USB-C with PD.

HI,
First of all (I'm using a usb tester) I noticed the cable has nothing to do with this problem. I have one BaseUS 100W PD charger, one UGreen 36W PD charger, one BaseUS 65W power bank and one 18W power bank. They are all able to provider PD charging at 12/20V at their maximum advertise wattage with my devices and a usb-c laptop. They can also provide 9V/3A (tested).
I noticed then when the battery is below 60% connected with a usb-c cable they all default to 9V/0.45A and sometimes even 0.22A (last night I left it to charge and in 8h it only charged 7%!) when above that you can get 5V/2.5A which is much better.
So I'm not sure what exactly those PD chargers are missing if they work with all other devices.
Also I find it weird you can see 25W from franco kernel since the phone shows half of the wattage being a dual battery. So yhat would be a real 50W.

Latest OOS?

Yes of course.

Bro, something is wrong.... I just tested my google chromecast with google tv power block and cable and I am getting this:

I'm sorry what is the link of this charger?

I don't know exactly, whatever google uses for this: https://store.google.com/us/product/chromecast_google_tv?hl=en-US

It's a 5V 1.5A so that value you see in FKM cannot be real.
You should use BatteryGuru and multiply by 2.

Well I guess this block is different. It says 5V 3A or 9V 2A, so 18W would make sense no? I'll try a different app. This is from the battery guru app and electron app:

Yes makes sense now. I'll try to find other chargers at this point. I know everything I have is not supported by this phone.

It's like u can't find a compatible charger lol whatever charger I tried charges at 9v 1.8a until the phone reaches 65% and then it drops to 4.5v 0.4a and it takes ages to get from 65% to 100%
Idk what the hell is this problem but I know for sure it's their dual battery design messed up for real

Could anyone try monitoring charging voltage and amperage across different charging percentages and report back.
And for monitoring use OnePlus toolkit it's baked in the rom, *#800# to access it then tap on enter and tap on tools to see charger option and then choose it.
It displays the voltage and current without having to multiply it.

There was a thread at OP forums about this issue.

I suppose the problem is also in the technology itself:
In contrast to USB Power Delivery and Qualcomm Quick Charge technology, which increases the voltage during fast charging, VOOC/Warp Charge/Dart Charge use a higher current than standard USB charging.
All versions of VOOC require a proprietary cable to work. In addition to electrical requirements like thickness (low electrical resistance) to handle the high currents without overheating, the VOOC 2.0/Dash protocol requires a fifth pin on the (USB-A to USB-C) cable to communicate through. Without such communication, the charger runs at a limit of 5 V/1.5 A. From VOOC 4.0 this limit elevated to 5V/2.0A.
On the Android phone end, the VOOC communication code is open source under GNU General Public License (GNU GPL) version 2 as a part of the modified Linux kernel, and has been used by custom ROMs like Lineage OS.
So i presume it's just not compatible with many PD chargers.

Oppo Gan Charger Kit supports 65W charging protocol，You can buy it about 80-90RMB on the Xianyu app 。There is also a power bank that supports 65W charging called Sdoutech but a little expensive , 400RMB/26800mah about four times for 8T

Mainly I want to charge with other chargers and power banks I already have not buying other VOOC chargers.

I don't understand why it can't be compatible with many PD chargers if PD is a standard. What would be the discrimination factor here?
I tried charging the Pixel 6 that supports PD with every PD charger I have and they all deliver 23W, while on the OP8T all stuck on 5W or even less sometimes.
