Third party chargers for the N4

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.

About AC adapter and its amperage

Hi all,
Ok, so I finally managed to order a 16Gb Nexus 4 and hopefully it will be with me in 1 week or so.
And I was wondering one thing regarding the AC adapter: I believe (pls correct me if I am wrong) that the original AC adapter’s output voltage is DC 5V, 1.2A.
I will need an extra AC adapter to keep it at work and I was planning to use one of those:
- The Sony Xperia P AC adapter will output 5V, 1,5A
- The Samsung Galaxy S AC adapter will output 5V, 0,7A
It is clear that neither of those 2 chargers will match exactly the specifications of the original Nexus charger (same voltage, but different amperage).
So, here goes the questions:
1) Is there any problem if I use a charger that will output the same voltage but with different amperage?... if not, which one would you use and why?.
2) how the amperage affect to the charging process?.
Thanks all in advance
PS: sorry for terrible English

You can use any charger up to 2 amps.

You must use a 5V AC USB Adapter and better no LESS than 1A
for Fast Charge.
AC Adapter I Use:
iPad AC Adapter 5V 2.1A at Work
PlayBook AC Adapter 5V 1.8A at Home 1
Original Nexus 4 AC 5V 1.2A at Home 2.
Our Nexus 4 will Draw around 0.8A when Batt lever at 0% - 80%,
then around 0.5A at 80%-95%, Final State 95%-100% will draw 0.2A roughly.
When 100%, Nexus 4 will use the AC power & the Current "A" show on phone
will like 2mA (0.002A) when idling.
** 1A = 1000mA

As previous poster said, do not go under 1.2amp.
I run the OEM charger in my bed room, a USB charger to my computer, and a 2.1amp charger in the car.

Why do you say not to go under 1.2A? Charging from a laptop is at .5A. I've been using a 1A charger since day one. Haven't experienced any issues with it.
Charging at a lower amperage shouldn't hurt anything, just charge slower. All you have to do is make sure it's a 5V charger. Amperage shouldn't matter but a lower amp charger will charge slower. As for a higher amp charger, the phone will only draw the amount of power it needs to charge so using 2A charger won't hurt anything either.

Also 2mA is 0.002A not 0.02 A

Since the charger doesn't actually regulate the charging itself (the phone does this) it doesn't matter how many amps it can supply, could be 100 amps, no worries. As long as it is 5V, the phone will draw as many amps as it needs.
Since the supplied charger is 1.2A rated, it's fair to assume that the phone will never actually try to draw any more than that, so there will be no benefit in going higher.
Going for a lower current charger will likely extend the charge time.

I use a 2.1 amp daily without any issues.

Wow guys!!... thanks all for your answers!!
So, if I understood correctly, the amperage will only affect to the charging time, meaning that by using the Xperia P AC adapter (1,5A) the battery will be charged faster that using the Galaxy S one (0,7A)... right?
Pls allow one last question: a few yeard ago, I think I read in some forums that a slower charging process could help to keep the batteries in the best conditions for a longer time... is this still true with modern batteries??
Again, THANKS all for your help!!

Yes, the .7A charger will take a little longer to charge you phone.
On the other answer, I think NO but I'm not as familiar with LiPo batteries. I would venture to say that .7A vs 1.2A (max the phone will draw but I think someone above mentioned it's even less than that when the battery is very low) is not going to make a bit of difference in your battery life.
One thing I do know about LiPo's is you do not trickle charge them. So while plugged in it will charge at the rates mentioned above until full and then it QUITS charging all together. Once the phone discharges the battery to a certain level, it will charge it back up again. Probably at 98-99%.

There may be one other thing to consider when selecting a third party charger. In the Nexus 7, the device looks for pins 2 & 3 (data) of the USB plug to be shorted in order for it to draw full current. If this pins are open (or have a load across them as is the case with iPhone/iPad chargers), the Nexus 7 will assume it is plugged into a computer and limit its draw to 500MA.
Not certain the Nexus 4 behaves the same way but would assume so.

setzer715, thanks for the answer... I think I will be using the Xperia P charger at work...
Thanks all for your help!!

I want to make this case clear. According to my Charging log,
Here is some key point.
Nexus 4 Max Draw Rate at Fast Charge Mode is around 800-900mA,
even you use a Charger that rated at 1A (iPhone Tofu), 1.2A (Original),
1.8A (Playbook), 2.1A (iPad).
Fast Charge Mode must be with Charging Cable with 2&3 pin Shorted,
or the charger itself have the 2&3 pin already shorted.
Therefore, 1A is a Sweet spot for getting Charger & Charging Time for
Li-Po/Li-Ion/Ni-MH Batt charging.
If you use under 1A Charger, eg 700mA or 500mA, it will take much longer
to charge the batt but no harm as well. Just too slow only.

The stock charger that came with my phone sucks, I use one from my epic 4g touch (gs2)and it charges much better

Left a phone on a charger all night with a long (10ft) cable and it couldn't even charge the phone over night. I know a 10ft cable will slow things down but my gs2 plug has no problem charging my phone. Search around and you'll find a few fail stories about the stock LG charger.

Question about the 5.3v charger

I don't know much about voltage and stuff, but with the 5.3v charger, I assume it's okay to use a 5v to charge the Note 3, it just might be a bit slower, correct?
Now what about using the 5.3v charger on the iPad Air? I can't find any info on its charger, or online, of what voltage it uses. will the 5.3v be too much for it or anything?

It's perfectly fine to use 5v, that's standard. The voltage the wall adapter puts out is not what will determine your charge speed, its the amperage your device draws - which I believe is capped at 1800 mah for the note 3. It doesn't matter what the amperage is (it can be higher), but the note 3 will only draw 1800 mah max and lower if the source is lower. When it comes to the 5.3v charger, there's a bit of mixed information from what I've gathered. Plenty of people have used it with no problems considering .3v is a fairly small difference, but there will be some that tell you otherwise. I personally avoid 5.3v just because I have plenty of alternative chargers.

If the source is lower, it will increase the time it takes to charge. But 5.3 volts as an output will actually drop to 5 once it is loaded by your device. Just like 5 drops to about 4.7 when loaded by a device. The unloaded output of a charger is always higher than when it is connected.

It's the device that determines the amount of charge drawn, the numbers on the charger are just the max-charge it can provide. (Think of it like a car. Your engine can go up to 200Kph, but the actual speed is determined by how much you tell it to give you.)
I charge my Note 3 with my 15V Asus TF700 charger. It still only charges at the max the Note 3 can draw.
Essentially a 15V charger can safely provide the 5V, but a 5V charger can never provide the charge for a device which requires 15V.
Besides, a USB2.0 cable can't go over 5Volt anyway, so your iPad is safe.

Now I'm not trying to be rude or anything, but I think you have a few facts astray here. If you can prove me wrong I'll be happy to learn since it has been awhile since I took circuits. First off your right about the device being a big factor in the rate of charge, in fact technically the charger is in the device, the wall adapter is just the source. The source will force a certain voltage, i.e. 5v or 15v, and can provide up to a certain current (amperes). The charger in the device then determines how much of this current to draw.
With all that being said, the reason you can use your asus transformer charger is because it only forces 5v unless the transformer is plugged in at which point it kicks it up to 15v. So your not actually plugging a 15v source into your n3, if it were possible you'd be on thin ice. Also, I'm pretty sure you'd be able to charge your asus via say the note 3 charger (really slow though), probably not while its turned on, but turn it off leave it plugged in for a few hours and you should see a change.

A USB cable is just a wire, if you put 5.3V on it then your device receives 5.3V (minus voldage drop due to the resistance of the cable but that's negligible unless you're using a cheap thin cable). That said, 5.3V should be within tolerance for pretty much every USB charging device out there including the iPad (which I think uses a 5.3V charger itself).

It's not undervoltage. The resistance "R" of the USB cable is fixed (varies from cable to cable, but is constant for any single cable), so as the current load "I" increases the voltage "V" lost across the cable also increases, according to V = I*R.
Given a 5v source, loaded to 1800 mA, you would expect to see 4.7v at the phone's end of the USB cable. The resistance of the USB cable itself comes out to around 0.1666666 Ohms in that scenario, which is a perfectly reasonable value for the gauge wire used in those cords.

In lieu of using higher voltage chargers to use with long cables, you can also use chargers that provide more current @ 5V or, of course, lower resistance cables.

I'm afraid not. The voltage will drop too far below 5.0V, the device will not accept the offered power, no matter how high the charging current. That's both based on physics and personal experience. Resistance in cables is an issue at 10 metres, even those with high gauge copper cores.

You are absolutely correct, however that isn't exactly what I was trying to share. I was trying to share a solution to situations where the charger cannot keep up and thus the voltage sags. I did not expect a 10metre situation. The longest I have is 5m. On my 5 metre cable, I don't notice any appreciable voltage drop from any of my chargers, so I generally consider it negligible. How much do you drop across 10 metres and at how many amps?
On a side note, I think the phone has some kind of safety when it comes to voltages. I just plugged in my 5.3V charger from my s5 into the s3 and it seemed to work fine. However, I also recently, and I only just realised this, plugged in a 7.2V supply to my S3 and though it did not charge, nothing bad seemed to happen. It was an off brand 5V USB Charger and when it died, it cranked up the voltage.

The voltage drop is dependant on gauge, copper quality and length. I never measured it at both ends but i estimate 0.3-0.5 volt based on what chargers do and don't charge what phones at 10ft. Note that i mixed up ft and metres lol, my cables are 3m. At that length voltage drop is an issue for me.
7v would perhaps be fine for a 10m cable I wish we knew the tolerance range of what voltages (at the usb in) common smartphones accept.

I think the reason the galaxy tab S tablets have a 5.3volt charger is to compensate a bigger voltage drop through the longer charging cable provided.
The voltage must be the correct voltage or near to it. I think from what others have said 5.3 is near enough to 5.0Volts.

Charging speed question (amps related)

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.

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.

Some questions regarding DASH charger, cable, and other phones

I'm aware to take advantage of "DASH" charging (5V 4A), you need a DASH charger with the circuitry, and a DASH capable phone.
1. Can I theoretically use any USB C to USB A cable with my OP5 and DASH charger, or will the phone limit the current? I understand cables may not support 4A of current, but I want to know will the charger and/or phone stop it from pulling so much current? What if I buy a high-quality cable off Monoprice? Or does the cable have to be "DASH Certified"?
2. If I were to plug in another phone into the DASH Charger and official cable, like say a Nexus 5X, how will the Nexus charge? The Nexus usually pulls 3A from a 5V charger. Can the Nexus still pull 3A from the DASH charger, or will it be limited to 1 or 2A?
3. If I were to plug the OP5 into another, non-DASH charger, what's the maximum voltage/amps it can pull? For example, the Nexus 5X charger is rated at 5V 3A. Would the OP5 be able to pull the 3A, or does it need some special circuitry? If so, what would it draw? 2A or less?
Last question: From what I understand if I use a laptop USB C charger, things should work okay- especially if the power brick shows it suppors 5V, 9V, and 12V. I assume the device will tell it to use the 5V line and draw whatever current it can. But what if I have a USB C charger that only says 12V on it? Or say 19V? Am I taking a gamble then? Let's assume this charger that is only rated at a high voltage is not a "shady" charger, and they followed the USB C spec properly. Should I be okay?
Thanks.

Any input or insight on these questions? I've read a lot about DASH charging, but looking for clarity on the above questions.

1. You can use any cable with your dash charger but your phone won't take advantage of the dash charging speeds and instead will charge at around 1.5 to 1.7 amps. So far I haven't seen a single cable no matter the brand working at dash charging speeds so the only cable I've seen working with dash charging are the official 1+ ones.
2. I don't have my Nexus 6p anymore to test this out but theoretically a 3 amp capable phone could draw the necessary amperage from the dash charger since the dash charger is capable of up to 4A. However, I'm pretty sure the phone will charge at the traditional 1 to 2 amps.
3. Amperage, as opposed to Voltage, is drawn by the devices themselves meaning a 5V 3A charger will always push 5 volts and can give up to 3 amps of power to a connected device. The amperage may be below or equal to the capacity of the charger, but never more. Modern batteries and phones have special circuitry embedded in them to protect them from over voltage or excess current and the OP5 is no different.
When connected to a charger, a phone will usually try to identify the charger it's being connected to, if if fails to recognize its capacity, the phone will reduce the amount of current to a safe amount that's below the charger's capacity. Seeing as there are many different chargers, like 2A, 2.4, 3A, 4A, phones usually fall back to a safe charging current that's within the lowest capacity of the most common chargers so even with a 3 amp charger, the OP5 will probably charge at between 1 and 2 amps even if the charger has a 3 amp capacity.
4. Computer USB ports are fine since they have a 5 Volt power bus and any extra current needed is passed through the BMC configuration line and/or the VBUS line only when requested by the connected device. As for using a higher voltage, since voltage is pushed to the device, is not a good idea to use a charger rated with a higher voltage that of the device being charged because you run the risk of overloading the circuits. Phone chargers used in cars usually operate at 12 Volts but they have DC/DC converters and resistors to reduce the voltage to the 5 volts required for phones and tablets. I'm not aware of AC chargers being able to operate with different voltage regulators.

1, No，you can only use official cables, but, I'v tested that oppo vooc cable+micro2typec adapter, can Also dash charge at 5v 4a,Turst me ,the charge chip is in USB C

In case nobody else does, I'll answer question 2 on Friday, when I get to the office. I'll be able to try it with several USB-C capable devices.
Hope I won't forget the dash charger home.

So, as promised...
Today I tried the following devices:
- Nexus 6P, LG 5, OnePlus 5
- Nexus 6 original charger (model SSW-268EU), OnePlus 5 original charger
- LG G5 original cable, OnePlus 5 original cable
I used Ampere to measure the values. All three phones were at around 50% charging state. Temperature of the phones was around 30 °C (+/- 2 °C). Measurement time was around 1 minute.
The results represent the maximum stable values (shown for at least 5-10 seconds). Where there was a variation, it meant that the reading varied slowly between those two. One value means that the reading stayed fixed at that value. Amperage readings are expressed in Amperes. No approximation made and any variation of less than 0.1A was not taken into consideration. (i.e. 1.4A = 1400 ~ 1500 mA).
The tests are not scientifically rigorous and should be taken as such. These results are purely informative.
On the horizontal are the charger&cable combinations. On the vertical,the phones.

If I forgot any details, don't hesitate to ask.

Thanks for the information! Your tests are exactly what I was looking for.

Dash Charger Stop charging at 83%
Is there anyone facing dash charger stop to charging at 83%? But with another charger can continue charging until 100%....

On the topic, there is a QC to VOOC adapter on TaoPao that someone tested on the OnePlus subreddit and it apparently works. I wonder how exactly it works, though. Apparently it's capable of getting 3A from a standard USB-C and QC 3.0 wall wart.
