I'm planning to set a tab S4 as my car dash. I want to know if it is possible to fast charge the device while using OTG at the same time.
I know that it will charge the device, but if it doesn't fast charge, even though it charges the battery capacity will decline because of the constant use of the display.
I have a usb hub which has PD 3.0 charging capabilities, but it shows as cable charging only with a 18w charger.

Hi guys,
I've noticed that my galaxy s4 mini 3g comes with a 1000 mA (1A) charger and it charges at a very good speed compared to when I plug it to an ordinairy USB port (500mA only I believe) on the desktop.
It gets warm after a while while charging using the official samsung wall charger (1A)
I plugged it in my battery bank where the output is said to be 1500 mA and it charged up much faster but gets a little more warmer in the back.
I have an ipad charger here rated for 2.1A but I haven't tried it yet..
I want to find the fastest but also a safe way to charge my phone in order for the battery life to become longer before I need to buy a new one. So I want to ask you guys here in the forum what chargers do you use?
A good read that made more familiar with charging via USB:

For the battery life to remain long you should stick with lower amperages. The 1A charger should do you fine. USB ports are typically 0.5A, unless its a USB3 port which gives more amperage I think.
I've used a Mega 6.3 charger on the S4 mini before (2A).
Howdy,
Galaxy S4 running 4.4.2 and a Samsung Smart Dock attached to an HDTV via HDMI with a Logitech wireless keyboard/mouse plugged into the dock. The dock is plugged into the wall via the Samsung adapter that came with an old S2.
For one reason or another (I think it is power usage of MHL) the phone slowly discharges even when it shows the charging symbol on the status bar.
Just wondering if anyone else has come across the same problem and if there is a way around it?
Cheers,
JL
The S2 adapter is probably 1A or less. S4 adapter is 2A, which means it charges at 2x the speed. While using HDMI with all your accessories, you are draining at a faster speed than you are charging. Switch your S2 adapter to S4 adapter or get any 2A wall chargers (those are $10 or so), and your problem will be solved!
I have an extra adaptive fast charger for my note edge and wanted to know if it would be ok to use for my tab s over the included one. I charge both of them on the same night stand and it's a pain to try to figure out what Samsung cord is which because all I see is the micro usb end, not the wall plug. If I plug the wrong one into my note edge I don't get the fast charging and the only way to know is plug one in and see if the "adaptive fast charger connected" notification pops up. So will using the fast charger on my tab s hurt the battery on my tab, or will it charge it slower/faster than the included one? Thanks in advance.
It should charge as fast as the Tablet allows - it will negotiate a speed with the charger for how fast It can be charged. It shouldn't cause any damage.
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.

Wondering if anyone else is having a similar issue..
I have an Anker PowerPort Atom III Slim 63W with a 100w USB-C to C cable
When plugged into the 18w or 45w port on the Anker charger, the ZF3 activates Super Fast Charging for a few seconds, then turns off, then a few seconds later starts charging again, then turns off etc
The only way to stop this is to disable Super Fast Charging on the ZF3 - but then its just standard, slower charging
Charger works fine with Note 10+5G (Super Fast Charging) and other devices
Cable works fine with other chargers
Using a different cable with the Anker charger doesn't fix the problem
Is the Anker charger just simply not compatible with the ZF3?
Does the Samsung 25w brick charge it normally?
Erratic fast charging is one of the signs of a battery failure.
It sounds though likes it's incompatible with the Fold.
If fast charging parameters aren't fully met, it will disengage.
If charge start battery temperature is below 50-70F
Above 101F
If battery charge state is above 75-90%
If display/phone is active*.
*screen off listening to bt with Poweramp doesn't skew the charge curve.
ZF3 Super Fast Charges perfectly fine with other chargers, including a third party WJOY USB C Charger 65W that I use.
The problem is only with this Anker charger.
I think the Anker charger is simply incompatible with the ZF3...
The issue is 2 fold. 1 - that charger doesn't support PPS or the new version of PD, so you can't get super fast charging. And 2- It supports PD, however it's an older protocol that only Google and Apple phones use for "rapid charging", so you can only use standard fast charging.
So it sounds like the phone is trying to handshake the PD signature from the charger for super fast charging, but fails once it realizes it doesn't actually meet the proper PD specs. Charging is very rudimentary, so it's going to keep trying because it keeps seeing "PD capable charger"
Simply disconnecting the charger from the mains, waiting 5mins, and then reconnecting everything seemed to do the trick - The ZF3 now Super Fast Charges. Seems like it was just a glitch with the Anker charger and it just needed a reset. Thanks for all your help
