Car charger 1a or 2a - G4 Q&A, Help & Troubleshooting

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

Charging Question

So I got myself one of these
http://www.amazon.co.uk/gp/product/B001KP3YWA/ref=oss_product
as it looked like a nice neat solution.
Now the output is 500mA and guess what? It is not enough to charge the phone. This I get and can see that the HTC charger etc is 1A so get why the 3rd party charger is not powerful enough.
But.
The output from a USB port on my laptop is 500mA also. This is per the standard USB specification.
So how come the phone will charge from this 500mA feed but not from a stand alone 500mA feed?
What gives?
It should charge the phone, even it is only 500mA. However, it will charge a fair bit slower than a 1000mA charger, and may not charge at all if you're actively using the device.
Typically, 500mA car chargers are the problem, as when the used is being used as a SatNav the battery will run down faster than the charger can charge it.

Any reason we can't use a generic or old charger ?

I have a couple of generic chargers I've been using with my note 2 for a couple of years. I realize these will charge slower than the samsung fast charge charger but is there any reason we can't use them or will they impact battery life (I would think they would increase battery life); i supect the answer is that they are fine but maybe battery technology has changed and there is some 'smarts' between charger and battery that would be damaged by these ?
No issue using your old charger except as you mentioned it won't be fast charging. I do not believe that the fast charging will hurt the battery. The fast charge only works for the first portion of the charge then the rate of charge slows to a trickle charge.
U can use any charger but i recommend to use any charger with 2amp output as it charges quick 40% in 30 mins insteas of 50%in 30 mins with original.
Original charger has two modes 9v and 5v it charges with 9v untill 50% and switches to 5v after that.
I think the unit i use is a sanyo 800ma 5 volt. I don't mind the slwo charge as long as it can't harm the battery. This is only used during travel and office; @ home I use the charger that came with the device.
You can definitely use another charger. Like said before it wont charge as fast. The adapter that comes with the phone will charge your phone at 9v instead of the normal 5v. If you use a different usb cable with the charger it will still charge at 9v. If you change the adapter, it will charge at the normal 5v whether you use the another usb cable or the one that came with the phone. The usb cable is just wires. The wall adapter is what determines how fast it will charge...

What charger for the Galaxy Tab S

Hey guys !
I just bought an Galaxy Tab S (8.4) from eBay but it came without any charger/cable.
As it is a Micro USB port, there's no real problem, I have literally tons of usb chargers available.
The problem is that most the chargers/cable I used only charged the battery at a 0.3A rate (measured with an USB voltmeter + battery app).
I know that the original charger was 5.3v 2A. I tried with some powerful 5.0v charger (3.0A/Quickcharger 3.0 compatible from Anker) but no luck so far...
Is there a specific charger/specs know to work well with this pad ?
I'm using this aukey 3.0 compatible wall charger and so far it's charging as expected
How fast does it charge ? I only get 0.3A with this charger, which charges really slow...
0.3A is 300ma i am surprised the battery charges at all at that low rate, My 10.5" draws 1700ma from my third-party chargers according to my usb monitor, I have managed to charge it as low as 1000ma from my notebooks usb port, but you need a charge only cable as a data cable will not charge at all.

Is Qualcomm quick charge 2.0 supported on the OnePlus 3?

Hi guys,
Just a simple question... Is Qualcomm Quick Charge 2.0 supported on the OnePlus 3?
I know there is Dash Charge (which is great), but I have a powerbank which supports Quick Charge 2.0...
I want to know if it wil charge faster than a regular 5V/1A USB port.
Thx!
Same problem here, would like to know this too. Can anyone with a OP3 try and let us know the different charging times with a normal charger, QC QC2.0 and Dash charger?
Sent from my LG-H955 using XDA-Developers mobile app
I don't have a Quick Charge charger, but with another charger the OP3 pulls around 1.5 A @ 5V = 7.5 W from it. This is the USB compliant amount i think.
I don't think that the OP3 supports any version of Quick Charge... But with a capable charger (non-Dash) it's pretty quick, too! In my car it gains fairly quickly, even though i'm navigation with google maps and i don't have a Dash-Charge car charger! With previous phones (LG G3 for example) the phone even LOST battery capacity while being plugged in!
Normal 5V 2.4A Charger: 1.5A @ 5V
5V 3A Quick Car Charger (for Nexus 5X/6p): 1.5A @ 5V
Quick Charge 2.0 Wall Charger: 1.5A @ 5V... you're beginning to get the idea...
Dash Charge Wall Charger: 3.5A @ 5V
And I tried a genuine 5V 1A iphone charger, 0.5A @ 5V

This.
Just did the test by myself with the 'Ampere' app.
Battery was at 55%.
Dash Charge: 3330 mA
Qualcomm Quick Charge 2.0 Charger: 1420 mA
PC USB Port: 380 mA
My Nexus 6 charges at 2050 mA when connected to the Qualcomm Quick Charge 2.0 Charger.
Is it in some way possible to 'tweak' the OP3 so it can take 2000 mA when connected to a QC 2.0 charger?
I'm using ElementalX kernel btw.
OP3 is not quickcharge compatible so when connected to a quickcharge charger, the charger is in normal mode at 5V with a maximum of intensity that depend on the charger.
BUT the OP3 have only 3 charging step, one at 5V 0.5A, one at 5V 1.5A and then 5V 3.5A only if it's connected to a dash charger with a dash cable (or a oppo vooc with an adapter).
So for example, you connect to a 5V 1A charger, it will charge at 0.5V, like on a computer. But if it can draw 1.5A, it will do it but not above that unless a dash charger.
I tried many charger and it will not charge at another intensity.

SM-R800 charging dock - possible to use charger >1A?

The charger that comes with this phone is rated 5V 1A. I was looking at third party chargers on eBay so I could have a spare one to use at work. Some of them mentioned that the maximum input current should be 1A. If I use a 2A charger with the original or third-party dock, is this likely to damage the dock or the watch?
Neither. The input rating shows the maximum it can take - i.e. using a 5V 2A charger, it will still only take 5V 1A.

I use a 3.5A charger and charge just like with 1A
You can use a higher rated adaptor/charger, but you won't really charge at any faster rate. Still, if you are buying new it does make sense to buy a higher rated adapter so you can use it for other devices later on.
