I just got a new car charger which has two ports. 2.4A and 1.0A. The 2.4A is "designed" to charge tablets and 1.0 is for phones. I bought this thinking that it would charge my S5 faster, but it doesn't seem to charge at all. It charges all other devices like my iPad, tablet, iPhone, etc... but not the S5. Does the S5 have some amp protection, preventing it from being charged by this?
it doesnt charge my girlfriend s5 too . i bought a power block which have 3 2.4a port 1 smart usb 2.4a and smart usb 1a it will only work on the smart .
i tried charging with ipad charger dont work . portable charger that is 2amp it work. Note 2 stock charger work too . the verdict i have is you cant use any charge that is above 2.0a.
Not true , I charge with my iPad charger just fine.
Also I'm pretty sure the charger doesn't push 2.5amps,
It just means it should be capable of supplying that if the device tries to take that much.
The device plugged into it only draws the current that it can.
What CAN happen with portable chargers is that when the phone nears 100%, it goes Into trickle charge mode with low
Current, and then the portable charge thinks it's done charging so turns off, and the phone never hits 100%. That's why they have a special port for android/iphone on some of them.

Are you using stock kernal or custom ? because seriously i tried for the whole day . it just cant work. i am on lastest stock fireware and kernal SG.
It worked fine with stock straight out the box last week and at the mo it's running 0x0 rooted
I charge mine with dual port car chargers 1a and 2.4a regularly. 2.4a is much faster. But I'm not sure if one or the other has an effect on battery longevity. Stock S5 out of the box with Rogers.

Ive noticed the stock wall charger delivered with the Nexus 4 is rated at 1.2A, 5.0V. My old phone had a micro usb charger at 0.8A, 5.0V. I imagine the N4 will charge on the lower rated charger, but would take longer. Isnt the standard usb rated at 0.5A? My desktop PC has a new Asus board that has the Charge+ 3X Faster Charging, which I would guess means the usb can pump out power at 1.5A. Looking around for a car charger and additional wall charger, I imagine the N4 would be fine with a higher and lower rated charger? Or should I stick with 1.2A or less? Ive seen car chargers at 1.0A, 2.1A, and 3.0A.
the n4 will only take the current that it needs. a higher Amps- rated charger won't hurt it.
i use a 2.5A portapow quad output charger, the extra power of which enables the charging of multiple devices simultaneously.
I bought this charger for s2 when I had it.. and sold the phone immediately. However I still have this charger. Now what I want to do is, keep one charger (stock) at home and the other (Nokia one...which is also Original) at my workplace. I want to know, is it compatible? As the manual say, u shouldn't use 3rd party chargers. So I want to know your expert opinions "before" start using it on N4.
Thank you
I use my old blackberry + LG car charger
^ You think this would go fine with my N4?
The Output/Input is all same.. only 160 mA is diffrent from the Stock charger. So I don't really know.

I charge mine from an HTC wall to usb plug, then to a thermaltake usb extender, then to a random usb to micro cable I found so it can reach to my bed so I can listen to music in bed after I fap.

Hello,
Just noticed that S4 comes with 2A charger while S3 come with 1A charger. I have place where I charge a bunch of different devices in the house which has micro-USB port and all of them are using 1A. I'm wondering what repricussions I can have if I add 2A charger to the mix and will charge old devices with 2A charger and vice a versa charge S4 with 1A?

It will be fine, I charge all my devices from my ipad 3 10W/2A @5V wall charger. Bringing one charger while travelling reduces the clutter I have to pack.
Basically if your devices are working properly, they will only pull the power they need to charge. The S4's 2A charger is capable of supplying up to 2A's but is fine supplying less if the device your charging uses less.
The actuall charging circuitry that controls the battery charging is in the phone or device, not the wall unit. The wall unit is simply the power supply.
As acruxksa mentioned, you'll be fine since the device is in control of how much power it pulls from the charger (as long as it is working properly, that is). The only thing that you may notice is when you are charging the Galaxy S4 with the older 1.0A charger it may charge slower.
Have a great day.

And if in doubt, look at it this way; the phones will charge off a USB port on a computer - this is 500ma (0.5A) - so as long as your device will charge off a usb port, it will charge off a wall charger that supplies at least that much amperage. New iPads will not charge off USB ports, but it doesn't hurt them to plug them in.

Yes it does but as the previous reply said it takes longer.
I used the old s3 cable at the office charging s4 but it takes long time to get the battery % up. It usually takes my s4 from 1% to 100% within an hour and half time but with the s3 cable it takes good 3 -4 hour or so.
I wouldn't take the s3 cable for travelling though. it will take too long for me to charge in coffee shops and what not when I am moving around the destinations.
So far, I am very impressed with the charging time of S4.. Love the device.

I don't understand why all current control is on device itself why not manufacturers just suppl 3A chargers for all the phones since it can be used for any device out there.

Good question. Maybe because the higher amp batteries have not been out that long compared to all the years smartphones have been sold. They may start making 3A only. Also, companies may sell less chargers if one size fits all. No need to buy a new one when you change phones.
I do know when I charge the S4 with my One S charger it does take longer, as mentioned, and very slow off USB. The One S charger end also gets somewhat warm charging the S4. The S4 charger does not. That would lead me to believe it is pulling a little more current than charger was designed for. But, probably not an issue. USB does not get warm. But, is a good quality one and heavily shielded.

In case someone buys a 10amp cheap charger and ends up frying the phone. Thus Samsung protects it self from dummy users and from million dead phones warranty swaps.
I'm using a USB car charger that puts out 2.1amps and its super fast. USB 2.0 on my laptop takes a while to charge it. Some times I use iPhone charger with Nokia cable or with WD hard drive USB wire. They all work just fine but charge at different rate.

The bigger the charger, more expensive it is. Manufacturers want to save money.
Wow. Way to necro this thread...
Necro--
Damn, thank goodness for Urban Dictionaries for OLD farts--
Had to look that one up
so if i will charge my S3 with a 2A charger i wont see any major change from the 1A, correct? I have the Boeffala kernel and at the AC charge is set to 1,1A so if i have a 2A charger i guess it should charge faster.
The phone will only draw the maximum it can. The 2A charger will charge it at the same speed as the 1A charger.

Maybe it is a placebo effect, but when I charge my S3 with my S4's charger it does seem faster. Quite a few of my coworkers that have used my S4 charger at work also thought it charged faster.
Either way I have charged my S3 with it very often with no I'll effects, so OP you should be safe to do so.

So we just upgraded to Note 3 from our galaxy 3 (wife and I)...
I noticed the charger is a 2 amp charger compared to the SGS 3's 1 amp.
I started reading some threads here and found out the USB 3.0 cable will not charge the phone faster unless it's plugged into the computer.
Apparently the PCM also limits the phone to charging at 900ma. (not verified)
so I'm curious now.... at what amps does this phone charge? I'm trying to get a spare charger to keep in the car, and also trying to get a usb car charger if I can benefit from the 2.1 amp one instead of the 1 amp one that's in there now....
Can anyone tell me if I should get a 2.1amp charger or stick with 1 amp chargers as the spares if it'll still charge at 900ma?
I'm using USB 2.0 cables btw. (unless I can charge faster with the USB 3.0 when plugged to a car charger or the wall, which I apparently won't from my research here)
While I await for responses, I will plug the charger into my voltage/amp reader and we'll see how much power is being drawn, which might give an idea as to how many ma it's charging at.
For whoever that wants to know this information, these are my findings from my meter that is able to measure how much power is being drawn (kill a watt P3)
with the stock charger and USB 2.0 cable (3.0 made no difference) the phone will charge at 900ma with the screen on. If the phone is shut off, or screen is off, it goes to 1500ma. Very steady at those.
with the SGS3 charger that I had, it's a constant 900ma whether screen is on or off... (1.0 amp charger)
now I guess I will have to see if this is the case with any 2.1 amp charger, or if it's specific to samsung's charger with snapdragon's quick charge feature. I believe only certain chargers allow use of this.
I don't know, I'm getting 1800mA by using stock wall charger with USB3 cable and 450 with USB2 cable. I know GS3 would charge at faster rate when using original Samsung wall charger and cable, which had data lines shorted, not sure if it's the same with Note3.
I don't remember for sure, but I think charging rate from computer was pretty much the same 450mA regardless of USB3 or USB2 port or cable. I remember this because I was surprised they didn't take advantage of higher power ratings with USB3, but maybe it was just my particular setup. I used application that shows charging rate, so all is with phone on, but it makes perfect sense, about 2 hours from 0 to 100% charge, if you allow some extra time for trickle charge at the end, losses and usage.

You can't compare that app to a meter that shows you the actual current being drawn
Sent from my SAMSUNG-SM-N900A using Tapatalk
why not? How do you think your meter is working? Phone has similar IC. How did you come up with your numbers first of all? I thought you plug Kill a watt into outlet and it shows what the charger is using at 110v and at about 10 watts(or is it 220-240v for your location), your unit maybe at the limit of accuracy, since the amperage would be somewhere around 100mA, where your device is designed more for larger power consumption like fridge or TV running 300-1000watts and few amps. Is your unit somehow capable of measuring what the charger is outputting and if so, how?
BTW you can't get more than 900mA from PC even over USB3, thats the max limit.
I checked again: galaxy S3 wall charger is giving me 600mA, Note3 charger with USB2 cable gives me 1200mA and Note 3 charger with USB3 cable pumps out 1800mA, computer USB gives 450mA regardless of computer port, but there is something wrong with the USB3 cable that I got, is not connecting properly and I have to wiggle it to connect so maybe bad cable is the reason I don't get higher charge rate from PC USB3.
so i lost my fast charger which i didn't didn't use anyway as i kept fast charging unchecked in phone settings
now i got a new romoss charger which is a good charger AFAIK. it is rated at 2.1a, plugged it in and it took too long to charge. i downloaded an app called Ampere to measure the current and the maximum it gets is about 1000mA.
i thought the new charger was ****ty so i tried my friend's LG charger 1.8a and got the same results. tried another 2.1a samsung charger and nothing exceeds 1a.
is it something wrong with my phone or is it software related?
i'm using eRobot's newest rom with spaceX kernel (also tried googymax and suemax kernels). tried to check the fast charge option and again, same results.
any opinions or thoughts are much appeeciated
thanx
You need a Qualcomm Quick Charge 2.0 compatible charger in order utilize adaptive fast charging on your Note 4([email protected] & [email protected] output). Buy new Note4,Nexus 6,Motorola X Style charger. Also make sure your USB cable is undamaged/good quality, since not all cables actually support fast charging.
i dont need to use it as a fast charger, i just want it to charge with 5v 2a which the chareger is capable of
Hi,
Selecting a charger for mobile devices seems to be confusing nowadays, atleast for me[emoji16].
Can help me how much power does the S7 edge needed for Fast Charging and non Fast charging? I understand that the original charger included in the box has 5V 2A or 9V 1.6A output. Am I right to say that when fast charging is off, it will use the 5V 2A and if it is on it will use the 9V 1.6A?
Reason for asking is, I am using the original charger at home and my old htc charger from M9+ in the office. But when I use the htc charger with 5V 1.5A output, charging suddenly stops at 50-60%. I observed that the htc charger gets hot than its normal but my phone doesn't get hot. I turned off fast charging when doing this. It seems that the htc charger cannot handle the s7 edge and stops at certain point when it gets hot.
Now, i'm checking which wall charger should i buy to use in the office as it seems i cannot use an ordinary charger on newer s7 edge device. Am I right to say that the minimum requirement for power output for s7 edge is 5V 2A? It doesn't matter to me if it is just non-fast charge as I normally on my desk all day so non fast charging is okay.
Please help. I need an advise for this.
