[Q] Highest Wattage/Amperage AC Charger Needed? - Sony Xperia Z Ultra

I'm looking into AC charging adapters and want to buy the one that will charge the phone the fastest. I've found a 20 watt, 5 volt, 4 amp one. Is anything more even powerful even useful?
TIA

The PHONE asks for the power from the charger.
If the phone doesnt ask for more than 2amps, for instance, it doesnt matter if youve got a 100amp charger, it wont give it any more than 2amps.

panyan answers ur question.
However you can reduce the charge time by looking into buying a quick charger 2.0 as the S800 supports this. I repeat: version 2.0! 1.0 does not work with S800.
Details here: https://www.qualcomm.com/products/snapdragon/processors/800
For example:
http://www.ebay.com/itm/Qualcomm-Ce...682?pt=LH_DefaultDomain_0&hash=item35ec14a922
or
http://www.ebay.com/itm/Qualcomm-Ce...187?pt=LH_DefaultDomain_0&hash=item4d333ddd6b
will work with the phone. I don't have any quick charger so I don't know how much faster such charger act compared to a normal dc adapter.
The main advantage of buying a charger that has more amps output is that the unit will not heat up as much as compared to a 700mAh-1.5A charger. Because it has more performance to give than a smaller charger which is always going at full throttle.
But as panyan said. Your phone won't use more amps even if u buy one that can output like 20 amps..
And as many here has noticed. In the lollipop roms charging the phone is now ridiculous slow. Instead of 2 hours as we saw in KK roms it now takes like 4-6 hours.
In kitkat I topped 1,5A but now I get like 400mA-650mA. Dunno why they changed this in lollipop..
The disadvantage is just a miniscule thing to not even care about.
A charger with higher amps output can have a higher idle current then a smaller charger.
Instead of using something like 0,1W per hour a larger charger might use 0,15W per hour.
There's no linear formula for how it works but it can happen.. you might care about care about this if you are a controlfreak with the elecric bill.
This only applies if you leave your charger in the socket all the time like I do. Some people unplug it some just leave it in ready to charge the phone next time.

We have had a discussion about this on the forum before and i dont think the ZU is supported:

hmm strange... I don't really have much say about this. I have never tried it.
Did anyone around here on the forum tried buying a quickcharger and try?
How would you even know it's working? Is there any verbose output in the catlog or dmesg?

No idea unfortunately, i dont have a quick charge 2.0 charger

I bought a Qualcomm Quick Charge 2.0 charger and it doesn't work on my c6833.

Thank you! Finally someone bought one!
Now we have the answer. Quick charge does not work.
Edit:
I saw something about that quickcharge has the same connector BUT it uses 7 pins instead of 5 as a regular micro usb cable.
And looking into a microscope I can see that the Z ultra micro usb port has 5, five pins.
So the missing part might actually be an hardware issue here?
Värt att notera är att Micro-Flip inte har stöd för QuickCharge eftersom kontaken endast har fem stycken pinnar framför sju stycken, vilket krävs för turboladdning

Translated into:
It is worth noting that the Micro-Flip does not support QuickCharge because it only has five pins on the plug instead of seven, which is required for turbo-charging

The input and output numbers are considerably different from the oem chargers. I recall reading that using such generic chargers can significantly shorten our battery life. Perhaps someone with knowledge about electrical circuitry can comment.
It says 550 mA output. This charger is only half the oem output. It will take longer to charge your phone.

i think you are looking at the wrong numbers. this is what my charger says(charger that came with box)
PHIHONG
AC ADAPTER
MODELSAA05A-050
HTC PIN:79H00055-01M
INPUT:100-240V~
200mA 50-60Hz 13-20VA
OUTPUT:5V==1A LPS
the android charger guy says
Sciphone Dream G2
Model: G2
Input: 100-240V~ 50/60Hz 0.15A
Output: 5.0v 550mA
if you look at the output specs, the output on the android guy is half of the OEM charger. the 200mA is listed under input.
and the charger i used thats similar to the android guy is this:
http://cgi.ebay.com/USB-Charger-AC-...|66:2|39:1|72:2123|293:1|294:50#ht_2218wt_973
i used it on my shadow and tilt, i did notice that the charger charged my phone slower so i went back to using the OEM
also to have a clear comparison. the MOTO RAZR charger has the same specs as the android guy. and i have used the moto razr charger on all my devices before(whenever my cat would chew up my OEM chargers)
Yup, you guys are right. I was looking at the input numbers. Thanks for correcting me.

How quickly would they charge with 3A...

3A would be twice as fast as the stock wall charger and if yours is 1A, it'll be thrice as fast.

Li-ion batteries are smart, so are the chargers. If possible check reviews about whichever 3A charger you pick first. Battery won't get damaged because the chip they use will prevent charges heavier than they accept. Its all about if anyone's willing to spend the extra money to perform this experiment and see if the charger will actually make a real world difference in charge time or not.
those things are just huge!

I'm thinking about buying one... would be nice in some situations to charge with full 3A but i still think it's bad for battery longetivity.

It's actually not that easy, usually a battery charges to 80% in half the charging time and to 80% out of that 80 in a quarter of the charge time. Guess what I'm trying to say is that charging is not linear, meaning the equation is more complicated

Why'd you limit it? Secondly the only way to find out is noticing the charge time I think.

Faster you charge lithium batteries, you reduce the number of charge cycles. I'd rather charge it slower, especially because you can't change the battery.

True,
I have multiple chargers, in the car I have 1.2A (Sony original car charger), in work I have 2.0A ( Samsung original charger )... but near the bed I have 0.35A (Sony bluetooth headphone charger)... while sleeping I don't need fast charging so I went for the lowest possible power...
please dont try high amperage chargers... might burn the chip!

[Q] Best car charger with quick charge?

Hey guys, just wanted to know if anyone could recommend a brand that offers 2.0 quick charge on the go. I did some homework and the names Powermod and PureGear seem to pop up the most. Any suggestions? Thanks in advance
I had the powermod and it was slightly too small for my car outlet so if you bumped it then it would stop charging. I think I had a lemon but anyway I bought the incipio one and haven't looked back
Also, can I use any USB cable to receive the turbo charge? I'd hate to keep hauling around cables from my house back into my car.
http://www.amazon.com/Ventev-dashport-Charger-Single-Includes/dp/B00QU9DEBW
I have this and it's great. It's got a very low profile, came with a flat cable, has an LED light (albeit not very visible), and definitely charges quickly. Highly recommended.

I use this one as well. Any USB cable will work. I tried an old ASUS cable with my wife's Note 4 and it said a quick charger was enabled. That flat gray cable it comes with is really stiff and I drive a manual so it was always getting in my way when shifting. I switched to an old USB cable I have that's more floppy.
This doesn't sit flush with the port though even though the design makes it kind of look like it does. It sticks out about a centimeter or so. It would be super hard to get out of the vehicle if it sat flush.
Thanks for all the replies! i've decided i'm gonna go with the PureGear
http://www.amazon.com/PureGear-Qualcomm-Charge-Extreme-Charger/dp/B00QQPG57K
Pretty cheap on amazon and I like the design, will report back with my opinion on how it works
Sorry for resurrecting an old thread but does anyone know a very good quick charge 2.0 car charger with at least 2 USB ports? One port could be quick charge 2.0 and the other port could be normal or whatever.
I saw the choe one that has 4 points but its getting mixed reviews and I don't think I really need 4.
Thanks guys.
Yes just buy a power converter and use the OEM wall fast charger that came with phone.
Definitely not trying that in my car....
There made for cigarette lighters. Its perfectly normal. Most new cars have them built in.
I wanted to get the Ventev dashport charger, but they seem to be out everywhere, or ridiculously expensive in the places that do have them.
I want to try and get one thats as flush with the socket as possible, because theres already very little room in that spot in my car.
Found these two:
Aukey 4.8A / 24W Dual USB Car Charger Adapter for Apple and Android Devices (The Smallest but Most Powerful Car Charger in the World)
SCOSCHE USBC242M 12 Watt USB Car Charger for iPhone/iPad/iPod Lightning/Micro
I admittedly don't know much about, and neither of these are QC2. I was just wondering if anyone has used, or knows if they would work good. Would there be much of a diff between them and a QC2 one?

How Do I Know If My Mi 9 is Charging at QC 4.0 Speeds

Hi Guys
Just purchased a Xiaomi Mi 9 along with a razer charger QC 4.0 charger and was wondering if the phone gives any indication that you are charging at QC 4.0 speeds.

Just the charging speed, QC4+ should be around 4A, if I'm not mistaken? Haven't checked, but I think that's about what you should get. My Mi 9 charges at 3.3A with the stock adapter.

I bought the Belkin QC4+ charger and it seems to charge the same at the stock Chinese model (8/128) adapter.
Mid 4000s mAh @4.4v
Take it for what you will. I bet anything is better than the Global brick I guess.
I know it's working because my phone charges absurdly fast.
Look for rapid charging on lock screen
Or charge turbo on charge animation
I am using the Hama QC4+ charger, no Charge Turbo and no Charge Quick/Fast displayed.
Wonderful charger
It does charge kinda quick, and the text shows Charging Fast, but that's it. Disappointed.
Could always use one of these, they're fairly cheap and quite usefull for checking port/usb output
or you simply look at the GSI lockscreen which integrates usb meter
shows volts, ampers, temperature, battery% and speed status

This was not my experience at all. I bought that belkin 4.0+ and it averaged at 2200... I don't think the phone does Charge Turbo or even Fast on 4.0 / 4.0 + because it isn't really a QC 4 rated phone. Offical Xiaomi chargers that do 27 w are running at QC 3.0 (look closely at the brick) they do however have an extra mode which makes the QC 3.0 charge TURBO... here is the confusion I beleive after buying a Hama 4.0+ and this Belkin 4.0+ you said works but doesn't charge Turbo.

MI9 with WSKEN magnetic cable

I just love the cables of WSKEN. I use them on most of my devices.
So also on the MI9... But sometimes I had more battery drain than other times.
I found the problem through BBS. The WSKEN connector activates a kernel wakelock. Which uses lots of energy.
It declares why I have it sometimes because I don't use the connectors all the time.
Now i am on Xiaomi.eu rom. Can other users on different rom with maybe the same cable report if they have the same or not?
Thanks.... It's a shame i can't use it anymore now I know this.
It's the WSKEN X1 Pro.

Where do you think the leads of the wireless charging coil goes to?? [emoji848]. And wireless charging generates more heat.
And let's not talk about efficiency.... Wireless charging is around 60% so 30-40% of the energy got lost.
And the wireless charger I have got is very noisy.
I'm not unlocked and rooted so I can't use BBS, but I've got the WSKEN X1 and I haven't noticed a dramatic battery life.
EDIT : There is indeed a wakelock. I believe it might be due to pins being shorted by design. Like CC1 & CC2 (plug detection) being on all the time, and the phone constantly asking ("yes, who is it?") and getting no answer.
I'm writing to WSKEN about this (and dual magnetic cables) to see if it might be fixed in the future.
I use wsken cable for my mi 9, but most of the time it doesnt charge my phone, sometime it does.
The cable works perfectly on my micro usb plug, but not on my type-c plug (for wsken mini1 & mini2)
I've tried the cable and the type-c plug on another phones (not mi 9) and it works perfectly.
But my phones charge normally with the oem cable.
Anyone can help?
Sorry for bumping an old thread.
I'm using WSKEN mini 2 cable and the USB-C adapter on my Mi 9 which works flawlessly, no drainage and the phone charges every time.
So @24ilham I think that you might have a faulty USB-C adapter.

The drain is not very noticeable, but I got it too and decided to remove the USB-C Plug.
As I said in my edited post, I believe this comes from the 4x4 USB lines on the outside being fused towards the USB-C inside, which got 8x8 pins. To be reversible, I believe they are shorting VBUS and CC1 or CC2, and since it's used for Power-Delivery negociation, the phone is constantly asking "Ok, you're a PD Charger, what are you capable of?"
Unfortunately, the plug is too small for me to test removing a CC2 pin, and trying to find if it fixes it.
Someone with a lot of patience could try to use a USB-C cable with splitted CC2 wire to extend a plug, but... a lot of trouble.
@24ilham I believe you have a faulty USB-C plug as well, I have never had a problem with mine.
