[Q] Can I charge my arc with 1A?

Hi,
I've lost my charger, and I don't know if I can charge it with a charger with 5v - 1A or not, what I do know is that charging with USB is 5v - 500mA.
What's the power of the SE Arc original charger?

On the charger it says output 5V 1A
Is that what your looking for

It's Exactelly what I'm looking for thank you very much

The original SE charger for the arc is the GreenHeart charger EP800. It has got an output of 5V; 850mA.
As far as I know, there's no SE charger with an output of 1A. I've seen chargers with 500mA, 700mA and the 850mA.
My charger got fried during a power surge while holidaying in India so after asking around on the forum, I bought a Nokia AC-10N charger with an output of 5V, 1200mA. I've been using it without any problems. Pretty happy with it. Charges the phone much faster.

Thank you, that helps very much, but I heared charging the phone with higher voltage or higher Amperage can charge it faster, but it lowers the battery life on the long terme, it's appreciated to charge it with lower power in order to preserve battery life

Totally true on all counts. You can really use ANY usb charger to charge your Arc, but the higher the mA the faster it will charge. And the higher the mA, the less overall life your battery will have. If it's normally supposed to be good for 5000 recharges, it might drop to 4000 recharges (just numbers pulled out of thin air).
The "Normal" standard for USB power is 0.5A (or 500mA). The iPad for example uses 1.0A, or twice as much as standard. Now in the iPad's case, it refuses to charge with anything less. I don't know if that's true for the Arc or not...if so, and the SE charger is rated at 850mA, then that's probably as low as you'd want to go just to be on the safe side.
Personally, I'm willing to use the iPad's charger and charge a bit faster for a bit lower useful battery lifetime. A new battery I can buy....time spent waiting for my phone to be charged I can't get back

The amperage rating on a charger defines the maximum current the charger is capable of supplying. A 1A charger doesnt force 1A down the throat of whatever's connected to it, if you connect something can only manage to pull a maximum of 500mA then it will only get 500mA.
Consumer power supplies are generally constant voltage. E.g. a 5V charger will supply 5V to anything connected to it. The amount of current that the device will draw at 5V is the amount it was designed to draw, up to the limit that the charger can supply. If the charger cant supply enough, generally you just get slower charging (though some poorly designed devices will just refuse to charge at all). What *will* tend to destroy your device quickly is a voltage mismatch, e.g. connecting a 5V phone to a 12V charger.
You can get constant current power supplies. These ramp up the voltage in order to force the required current out regardless of what's attached to it (even if that's a human being). They are scary.

Exactelly what I was thinking, thanks.
Now I think I can charge my Arc with 1A without any problem, since it's gonna take only 850 mA from it

Car charger 1a or 2a

I have a universal car charger. With a 1a and 2a outlet.
Can you charge it safely with the 2a outlet?

If you want full charging speed, you want to use 2A as the G4 can draw up to 1.8A on a standard 5v USB port. Having a higher amperage charger won't damage it, as the phone draws what it needs up to what the charger supports, in this case it will draw up to 1.8A on that 2A port.
I'd look at getting a compatible quick charge charger though for the quickest charging.

use 2A, it wont mess it up, and the phone only takes what it needs which is 1.8

LG G4 charging

So the G4 comes supplied with a 1.8A output charger, and I am wondering whether it is okay to use another charger I have, which has a 2.1A output? As in will it damage the battery over time?
I have heard the G4 supports quick charging so I'm guessing in that case it would be okay.
Thanks in advance.

It's fine. The phone will charge at whatever current it deems safe, even if you had a 100A supply available.

Would it charge faster?

Maybe a little.
I get about 1600mA with the stock charger. And about 1900mA with my Quick Charge 2.0 charger, which can provide the equivalent of >2.1A. I don't have any good-quality normal 2.1A chargers available to try.
So the largest benefit you could see would be about 20%, if the phone charged as quickly as it does from a QC 2.0 charger. I doubt it would charge that quickly, personally.

Fast Charge

Hi guys, the Zenfone 3 deluxe supports qualcom quick charge 3.0 however it seems to be locked to the oem charger. Any other licenced qc 3.0 charger does not quick charge the phone. How hard would it be to get around this? Mainly for qc 3.0 powerbanks.

This is not true. I am using this one - https://www.amazon.de/gp/product/B01EH11AS8/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1
and the quick charge 3.0 works fine. I am still using the original type-c cable that came with the phone though.
Note: Make sure that you have plugged in the USB end of the charger correctly, push it all the way in. If it's only pushed in partially, then you may not be getting the full power for Quick Charge. You can verify this by using a tool like AIDA64 from the playstore and checking the "Charge Rate" under battery.

This is where I was told it's not supported.

Does it say Fast charging on the lock screen?

Update: Sorry guys, I realized that the OEM charger is indeed much faster at charging. Read posts below.

postimg.org/image/6wis1rux1/ - using licenced qc3.0 charger
postimg.org/image/ndr13s0pv/ - using oem charger.
Further test screen off
15min charge with licenced qc3.0 gives 13%
15min charge with oem charger gives 27%
Same test with screen on (playing video)
15mins with either charger yields about 15%, no noticible difference. Seems like the oem charger throttles when screen is on.
All tests are run when the battery is below 20%.
Same oem cable used for all tests.
Using the oem charger to fully charge my phone does it nearly twice as fast as the qc3.0 charger.
Don't know how your able to achieve the same speed regardless of charger

Hi guys, I've been experiencing the same problem with original charger, that's very big and it's seems that didn't have quick charge. I've a samsung charger and with samsung charger it wroks fine. I'll try to well plug thw original , but, it's thinner samssung's one.

Interesting ... I stand corrected now regarding the "Fast Charging" on the lock screen.
I never used the original charger because I bought mine directly from Taiwan which has an US plug which I cannot use here in Germany directly without an extension.
I tried the OEM charger now with an adapter and yes you are right, the Charge Rate with the OEM charger is 2 times faster than with other chargrers.
OEM charger - 2900ma charge rate
Other charger - 1300ma charge rate
---------- Post added at 11:29 AM ---------- Previous post was at 11:02 AM ----------
Actually now I'm confused. When I plugged in the OEM charger, it said "Fast Charging" for a short while and then it says "Charging". The Charge rate also came down from 3000ma to 1300ma and down to 800ma when the battery is at 90%.
I will do some proper tests with the different chargers and post back.

Confirmed: OEM charger is much faster than other QC 3.0 chargers

When the phone reaches 70-80%, the charging rate will slow down and just trickle charge. This is normal as it can be dangerous to keep charging at Fast speeds when the battery is close to full capacity. So if your phone has 80% and you put it on charge, it will not Fast charge regardless of the charger you use.

Thanks for the information

I can also confirm fast charging doesn't work with my QC 2.0 charger. Interesting thing to note is it outputs 5V - 2A and 9V -2A. My guess is this charger from Asus that fast charges the Zenfone 2 would work on our phones because it has the same outputs if you read the description. It's worth a shot and you could always return it to Amazon if it doesn't work.

It would be nice to remove the red light when the phone is charging. Maybe it's something that can only be removed after rooting?

Unfortunately, even though the charger referenced above has the same outputs it doesn't fast charge. Seems you can only fast charge with the included charger. At least we can use our own charging cable. If anyone gets another charger to fast charge the device let us know. It doesn't appear Asus sells the included charger on it's webpage yet.

Not allowing the standard quickcharge charger to work forces people to once again purchase / replace current QC chargers.
One tick to the CONs side of the evaluation.

At this moment, I don't really think it's a CON side...
The quality of all those QC2.x/3.x charger are not even today (may get better in future, however I really doubt those cheap, knock-off charger from China). Some are good, some are outright bad. QC is quite sensitive with the voltage/current delivered by the charger (it's by design of QC, I believe) and not optimum voltage/current will shorten the battery life at best, create danger at worst scenario.
LiPo battery is really not designed to be charged in high speed. The associated temperature issues needs to be check very carefully and charge current needs to be controlled strictly to avoid dangerous thermal runaway. It cannot only be done by phone itself and need co-work from adaptor (switching voltage, for instance.) Thus an adaptor which have good communication with phone is a safety requirement as far as QC is concerned.

Same with me. I bought a wall charger aukey PA-16 and a car charger Aukey CC-T8. Using the ampere APP, The original zenfone charger gets 2800 mAh. And the aukey chargers up to 1300 mAh.

K6 charger also does not enable Quick Charge function on 570KL
Input type: 100-240V 50-60Hz 0.5A - Quick charge 3.0 output: 3.6V-6.5V-3A/6.5V-9V-2A/9V-12V-1.5A - Power: 18W

I am wondering if someone achieved any solution to remove OEM charger lock to use fast charge with third party Qualcomm Certified Chargers/Power Banks?

Sorry to resume this thread but i lost my oem charger and id like to get one that works with the zenfone 3 deluxe and quickcharge. Can anyone post a link where i can buy it or maybe the model number of the charger? The EU version would be nice.
Thanks

Any solution to the original question?

ASUS locked the fast charge function to the OEM QC 2.0 charger that comes with the phone (it will NOT work even with other ASUS QC 2.0 - or 3.0 - chargers, only with the specific type/"model" that came with the phone). Therefore we don't get QC3.0 - as advertised - at all. The QC3.0 compatibility with 3rd party chargers, powerbanks and car chargers was disabled with one of the updates, I think it was the Android 7.0 Update (that replaced Android 6.0) that removed QC3 compatibility. So... any ideas how to re-enable the QC 3.0 functionality?

Quick charge was disabled for other chargers from day one. I'm still on marshmallow (Android 6.0) and only the charger that came with the phone works with quick charge.

Accubattery charging stats. Are these normal?

Let's take the charge current and voltage as 3000 mA and 4400 mV for best case scenario, the actual resulting wattage is 3000x4400 = 13200000 (i.e. 13.2W) which is still way lower than 18W. So what's the deal here?

It is charging the phone at 12V 1.5A = 18W
Charging the battery requires 5V Input (The shown 4400mV is the battery Voltage, not Charging voltage) so it needs to get Converted from 12V to 5V
In my case, It is charging at 12V 1.5A Converted inside the phone to 5V 3.4A = 17W (Software based Charging meter are not really accurate, it is even said in the app)
*To get full charging speed, the battery needs to warm up a bit, so the first time plugging the Charger wont be at full speed
*The battery Voltage will increase from around 3.8V at 5% to around 4.3V at 100%

So how to see this accurately in an app? Is there a way where I can check the actual charging voltage and current received by the battery?
Are you also using Accubattery?

Use hardware based charging meter like these. But its not really required, you can trust the Factory charger saying its 12V 1.5A.
What you can't trust is third party charger and cables in which case you should check using this.
