[Q] Wall charger vs USB charger

Hi,
I have noticed my phone charges much quicker via the USB on my PC. It takes about 2 hours to charge fully, while the wall charger takes 3-5 hours to charge like 40% or something.
The specifications for the wall charger are:
INPUT: 100-240V ~ 50/60Hz 0.2A
OUTPUT: 5.1V=== 850mA
I do'nt know what the specs for my USB port are? Can I check it in the BIOS? I have googled and found it's something around 5V 500mA, so technically my phone would charge slower...
This is how the wall charger looks like (you can unplug the USB-cable and use it on the PC since it's not a standard USB-mini connection).

Well the 500mA is the minimum spec for USB, basically they say its at least 500mA so that manufactures know how much power to expect and can design devices to run at that amount of power or less. That being said, USB can be anything above 499mA, I have seen a laptop put out 2000mA before even. So yes it is quite possible that your computer could put out over the 850mA of your charger. It probably won't say what its capable of delivering in your BIOS, if you really want to know you could try to find the specs for your computer/mobo/usb chipset. All that being said, you could always get a different USB wall adapter if you wanted to charge faster w/o a computer, just because it came with the one you currently use doesn't mean you have to use it (it is just a powered USB port after all).

Thanks, I will have to look into this, since someone else was implying my charger is broken...

Seems like your wall charger is defective, normally It takes about 1.5-2 hours for working wall charger to make the job done.
Standard PC USB port output is 5v==500mA, so it's strange that you can fully charge 1140 mAh battery just in 2 hours.

Need help fiding a charger

Hey guys, i need to find another charger for my galaxy nexus
I currently have this one

But i need an EU exit which is 2 round pins, is it possible to buy it somewhere ? i need the Samsung official one. I do have different adapters but its not the same like the real one, most of them don't fit. Moreover i use a EzoPower travel international wall charger but the speed of charging is less then half of the real charger.
Thx!

I use all sorts of third party chargers and they pretty much all work, What you need to look for is the rated amperage. the GN needs a 1 amp charger, most chargers out there for cell phones are rated at 750 mA or 500 mA.
You should also check to make sure the phone is in "AC Charge" mode, as this will indicate that it's trying to draw the full power from the wall charger, if it's set as "USB Charge" it will only draw 500mA regardless of what it's connected to. You can cheat this by shorting the two data pins, this will force the phone into AC mode.
something like this would do the job, at 2 amps, it's overkill, but I assure you, your phone will charge *Very* fast.

The trick, look for chargers designed for the Ipad that have a USB port, then use your own wire.

The EU model ETA0U80E,
http://www.expansys-usa.com/samsung...r-for-galaxy-note-5-3-eu-micro-usb-1a-224814/
it's thesame EU nexus come in box.
try also ETA0U10E, same, but without USB cable.

Get tronsmart 4 port car charger before, like their quality, find this news from their official site, looks like an interesting accessories for opt2.
if you already reserve the opt2, you can ask them for a free sample, they offer 100pcs free sample for the opt 2 users.
PS: It's a shame that oneplus two don't support qualcomm quick charge.

Yes I still dont understand the reason for not having such a basic thing specially when some of the reviews have shown 2 to have a poor battery life

Hang on. You are saying that you think we should get a quick charge charger for a phone that does not accept quick charge? I'm not sure I'm following why we should... I have a USB Type C cable that I got with my macbook, and I also have a USB Type C to C cable. I'm not going to be buying any more, because two is more than enough.

NO,i am not talking we can get the quick charge just with this accessories, i wish we could, lol.
I just like this design, don't need to buy so many type c cables, also tronsmart said this car charger support quick charge 2.0, so we can charge type c device, quick charge device together in the car.
and like tronsmart said, in near future, there will be more and more device support qc2.0 and use type c port (again,i don't understand why OP2 don't support QC2.0), this design will be the winner then. From Qualcomm site, Seems they have approved LeTV One Max, LeTV One Pro, so qualcomm welcome that design. type c + quick charge 2.0.
hope to see some reviews on this type c car charger with quick charge.

How to change the Max 1.5 A (non dash charging) speed?

So I was wondering, When I dont use My dash charger the OP3 only charges with a maximum of 1.5A eventhough im using the Dash cable.
Is there a way to up this number to like 2.0A/2.4A with a custom kernel or something in that matter?

No, if you're not using both dash charger and cable you're stuck at standard 1.5A.

1.5A is limit of most cables so.. u can change it with the chance of a melting cable.

I would be quite unwise to go higher.

I have blitzwolf USB c cables that can handle up to 3 amps

Then idk..

While it can likely be done from the kernel side, I would advise against it. Some of the OnePlus 3 charging circuit has been offloaded to the Dash charging brick so we don't know how the phone/battery would react to a higher wattage standard charge. Could damage the board/battery or cause a fire.

Exactly - this is the reason OP3 charges fast only with DASH and nothing else (except VOOC which is the same thing).
It doesn't have the necessary internals to handle other fast charging solutions. And everything above 1.5A at 5V is considered fast charging.
If it could be done safely, someone would do it already; the device has been out for months and there are many custom kernels and ROMs.
We have enough burning phones already *cough*Note7*cough*, please don't try to detonate our beloved OnePlus 3 ?

USB-C can support far more (As is the case with the Nexus 5X/6P doing 3A) so the cable is not the issue.
the fast charging circuitry being offloaded to the charger itself is likely the main reason the phone can't do more than 1.5A, and if so, SW mods can't change that since it's a HW capability the OP3 lacks.
Honestly, there was no reason for this phone to have USB-C at all in terms of charging speed - this could have been done the same with microUSB.

Using Pixel 2 With Sam Chargers

Will the Samsung adaptive wall and car chargers work with the Pixel XL 2?

If its USB c why wouldn't it ?

I'm referring to the fast charging aspect.

from my understanding it'll charge, but not at the fast or quick charge rates. pixel phones are supposedly following the USB-IF standards, so for faster charging, you'll want a USB power delivery power source. I believe I read a post by Benson Leung on g+ that the pixel will get the best charge from 18W chargers (6 volt, 3 amps?)

This is correct, Samsung uses the proprietary QC fast charging that doesn't follow the spec. Google uses PD. You'd need a PD charger to fast charge the phone.

charging yes
fast charging NO
you will need PD charger for that

PD for fast charge. Sammy won't work

18W in the PDrev2 spec is 9v2a as it does not allow >3 amps until you hit the 20v source power.

Found out today that QC 4 charges are PD compatible, so maybe?
