This one is good : [Qualcomm Certified] Tronsmart® Quick Charge 2.0 18W USB Car Charger
Opt among 1 output, 2 output or 3 output. However, please note that only 1 output port supports Qualcomm Quick Charge 2.0. Rest 2 are fast, however, not QC 2.0 Fast.:good:
what is it i need one ?
Check slickdeals. I've been using the $5 one (on sale). It outputs 12v so it charges the phone very fast.

Thanks for that. slick deals is having a promo on this.
However i was wondering s6 edge plus is not qualcomm based, instead exynos.
I was considering this one.
http://www.amazon.com/Aukey-Charger-Adapter-Smallest-Powerful/dp/B00M6QODH2
This is 2.1amp, and is the smallest, it can virtually snap right into your car charger port, without the protruding charger popping out.

Technology is same. High Volt, low Ampere. Any QualComm Certified QUick Charger would be compatible with Samsung's Adaptive Fast Charging. Atleast any branded ones, never go for any unheard brands. Usually Tronsmart, Aukey and Anker are good choices in average budget. Here's a video review I did for Tronsmart Adapter (Quick Charge) with my Edge+ :- https://www.youtube.com/watch?v=DR8W9ozZgAs
Also, please note that I have no affiliation with any of these brands, I just received a product for the review from Tronsmart and I found it really good. And I'm sure Aukey and Anker are equally good.:fingers-crossed:
Also, the Car Charger you are considering isn't fast charging compatible. Although it will not take much time with high Amp output (as specified), but its definitely not a fast charger.
Well, I am using CHOETECH’s Dual USB Car Charger with a dedicated port certified by QUALCOMM’s quick charge 2.0 technology so that I can charge my S6 Edge plus at quick charging rate even on the go. The main specialty of this charger is that it is not only charge the fast charging devices but also Apple devices like iPad Air 2 or iPhone 6 plus at much fast rate as compared to their original charger. You can consider to buy this from Amazon: http://www.amazon.com/dp/B00YX7Y3G8/

Thats very good info. Charging technology is evolving with the phones, and thats a very positive start.
The day is not very far when we might have multi thousand mah of battery juice and charging becomes a weekend job.
Do you mind taking notes while charghing 20% of battery with both the qualcomm fast charge, and the regular 2.1amp charger.
I've already placed an order for the Aukey 4.8A / 24W Dual USB Car Charger mainly because of the size. I'd really want a charger that can **** plush within the car's charging port.

Charging isn't a very quantitative process. First 20% of charging would never be same as next 20% of charging. Usually with fast charger, the first 20% would be amazingly fast while the regular 2.1 amp might take upto 1.5 - 2 times the time. Also, assuming two different devices have same sized battery, with the same charger, one might get 70% charged within 30 min while the other can get 80% charged. However, by the end of 100%, both might take similar time. Thats why, the % readings aren't very consistent or dependable. Its approximation. With 2.1 Amp charger, you won't loose much time, trust me. Also, I don't have the facts, but I have noticed that when I do the fast charging, battery drains out marginally quicker than when I charge through regular 2 Amp charger. Hope that helps.. :fingers-crossed:

Thanks that was good info. I've received my 2.1Amp Aukey charger.
I tried it yst evening while commuting back home from work, which is about 20min drive, and the phone was at at 50%, and it was able to charge about 30% in less than 30 mins. Looks promising. I love the form factor. you cannot evne see the charger plugged into the car port. Best of all, the car port's cover covers the entire charger when not charging, this way i dont even have to remove the charger jack every time i have to charge the car, just pluck out the wires, and snap the cover back to conseal the charger.

With constant gaming and videos watching (after working hours ofcs ), mine doesn't stay beyond a day. I'm very happy with that though. I have seen significant different in battery life when I keep the power saving mode on and it doesn't really impacts my gaming at all even though it says that power saving switches to the 1.5 ghz cores and stays that way...!
It doesn’t matter a lot but yeah the main thing is internal circuit and the premium component used in the manufacturing. All of the chargers integrated with Qualcomm Quick Charge 2.0 chip inside. But the best components used in the manufacturing plays a vital role. I can trust CHOETECH more in this area as they are offering 18 months warranty, which means they are confident about what they produce or deliver to their consumers.
Hey guys, as we all saw, the new note 20 charging specs isn't as good as the old one coming up to 25W rather than 45W.
But as for my past experience those on-paper specs aren't exact accurate and sure never fully explained.
unfortunately I don't own note 20 (yet?), so I can't share my highly detailed tests that I usually do, but those of you who own it and can share any data of test please write it down here.
Try to measure any of the following details:
* what charger(s) are you using? (Name / output powers / Power delivery version / etc... picture of the specs on it will be sufficient)
* what voltage and ampere (or watt) are being used (hold it few seconds to let it settle, it also should vary on the current starting point battery level, and wether screen is on/ off) (the more details you bring, the better)
* if you got no power meter than charging times could also be usefull (0->30, 0->50, 10->20, etc..)
after we get some tests here I'll sum it all up in a google sheets (like these: example1, example2, example3)
and after that we can get some recommendation of what 3rd party chargers are best to buy
If you are like me and like plugging a charger in every corner you probably want something good, with high speeds, and original is always more expensive than 3rd party ones so why not knowing the specs first.
Also we might find out that some charger can charge even faster than the original 25W one (what about 30W,45W,65W PD 3.0 chargers? what about PD 2.0? 1.0? etc..)
Your contribute will be highly appreciated!
I have an N9860 from Hong Kong. Normally I am happy to slow charge and have my charge settings set that way. Today, as an experiment for this discussion I enabled fast charging and super fast charging and connected to a 60W PD/QC4+ charger via a USB-C monitor.. The charger is branded Klearlook and was bought from Amazon in the UK a couple of years ago.
The phone is receiving/demanding only 15W at 9.2V, 1.6A. That is from 13% to 44%.
I removed the monitor in case it was interfering with handshaking protocols and it has had no impact on remaining time to full charge (now 58 minutes remaining at 46%.
Using the same charger I disconnected the PD cord and switched to an 18W USB-A port without a monitor. No change to remaining time to full charge.
So I'm getting fast charging, but not super fast charging from my combination charger - a charger that will happily run my Dell XPS 13 laptop from the PD port.
So then I unboxed the supplied charger and cord, previously unused. With the monitor attached I'm seeing 18W - 9V at 2A - and the phone says super fast charging, briefly, with the screen off and only the charging information displayed.
I'll just carry on as normal with my slow charging to 80% (thanks Accubattery) since that suits my needs perfectly well and should hopefully minimise battery degradation over time.
Thank you very much for that highly detailed measurement and review!
Results are pretty disappointing, your charger should have be good scenario
Hopefully (but doubt it) maybe others would find better results

The fact that maybe your PD QC4+ does not support PPS (the only way to enable 25W charging on Note 20 ultra or 45W on Note 10 plus).
Confirm that your charger does support PD with PPS protocol.
Yes, it's a bit annoying (to say the least) that note 20 is slower (downgrade) compared to Note 10 in terms of charging speed.
Regards.

I have no idea about PPS - never heard of it until now. The charger is no longer available from Amazon. I bought it in August 2018. Maybe it predates PPS. Anyway, a Google search found what appears to be the same product here....

Yeah, no mention of PPS anywhere, only AFC on the 3 non-USBC ports (limited to 18W).
And you are right Note 10 and S20 (the ones using PPS - 25/45W are 2019 phones), so the power supply being a 2018 product may lack the latest protocols.
I have a Note 9 (2018 product) and no ”Super fast charge“...
I had the same problem (bought a 45W car charger), just to find out it lacked PPS protocol, so no 25W or 45W charging speeds. I Had to return it, and carefully search for an updated version (more expensive) supporting it.

I have several chargers I use, but without any real testing, it feels like my 45w charger from Samsung is the best experience. I attached my charging log screen shots. 1%-100% in 1hr 13min. I get the super charging icon through the entire charge. I will try the same test with the 25w charger and see if there is any difference. It feels like it charges just as fast as my previous note 10+ 5g, which is why I got this charging block in the first place.
So... Phone is supposed to charge at 45W but, from what I've read, this is not really true...
I do not have the original 45W Samsung charger but a 3rd party multiport 90W charger, with 2 PD usb C and one A port.
Till yesterday I was using a standard usb C to C cable and phone would display "fast charging" with an estimate of 1h from 15% to 100%. Not really a good performance I'd say. Today I bought a certified 100W cable with a display showing charging speed (usb C to C). With this cable two things change: phone displays "fast charging 2.0" and charging speed has slightly improved: less than 1h from 12% to 100%. Still not fast enough for a 45W charging... And as a metter of fact after 5 minutes the display on the cable stops at 28W...
This matches with lots of articles that complain for the same problem...
I also have a Xiaomi 12 Pro with dedicated 120W charger + dedicated usb C to A cable (charger has A). I'm saying dedicated, because with any other cable (standard usb C to A or even the above 100W usb C to C with adapter) the Xiaomi displays "turbo charging" while with original dedicated Xiaomi cable it displays "120W max" and is indeed blazing fast: 15 min for a full charge!!!
What is strange is that if I use the Xiaomi 120W charger with dedicated cable on the s22 ultra, phone displays only "fast charging" without the "2.0".
Now... I'm not trying to compare charging speed of s22 ultra to 12 Pro: Xiaomi can achieve such a speed because the phones have two separated batteries that charge simultaneously, thanks to a power splitter that takes the 120W input and splits it into two 60W, one for each battery.
What I'd like to know is what's going on with the s22 ultra. I understand that a basic cable is not enough to deliver 45W, reason why I bought a better cable, yet I was expecting a big improvement, while it improved charging speed of less than 10 minutes. And as a matter of fact I've never seen 45W on the cable display. Maybe I need an original Samsung 45W charger instead of a 3rd party one?
Search the forum, there is a few topics regarding 45w charging... I have a 65w charger and 5a cable and the charger has all the necessary properties/charging formats needed to fast charge 2.0 the samsung, but it doesn't. i don't even get the fast charge 2.0 notification....In the end the difference between the 25w and 45w is very slim....will be a waste of money to purchase the 45w samsung charger....check the other discussion.....my charger takes basically an hour from 10-100%...it's good enough for now
Well good enough if not compared to the blazing fast xiaomi's 120w charge
Most of the time, it's only several minutes charging time difference when I have a "Super fast charging" charger or a "Super fast charging 2.0" charger connected. 45W charging seems to be over hyped by Samsung and it's not using full power to charge all the time.
I have the original new 45W charger and the phone charges from ~ 0% to 50% in approximately 20 minutes as advertised. It is faster by around 22% in comparison to the 25W fast charger between 0-50% state of charge. Afterwards they both charge in almost same way with the 45W charger being max 10 minutes faster by reaching 100%. You need a PD & PPS charger. There are only some 3rd party ones that manage to do same as checked by androidpolice:

My charger is compatible with FC 2.0 but as I said it depends on the cable. Real problem is that 10 mins faster between 25W and 45W is a real joke. Given this phones is energy hungry then... With the Xiaomi 12 Pro I don't even care: 5 mins and I get 30% of charge, although you need proprietary charger and cable

It depends on what you want. For example I am perfectly happy with my 25W charger which comes rarely in use because of me charging wirelessly and without fast charging over the night but I bought the 45W one to have the possibility to get that extra speed between 0 and 50, and my girlfriend gets my old 25W one for her base S22. Samsung has a different approach to fast charging and for me 120W on Xiaomi or 150W on Oppo/OnePlus is something I do not need although I am curious why Samsung did not make the same move yet. Just split the cells in two or three, give each cell a maximum of 25W and boom, you're in the mix and nobody will complain.
On the other hand they lied to us about last gen 45W charger which was useless so it is fair to say that their battery & charging department is almost on the same bad level as the Exynos software team if not actually worse than them

2 cells is exactly what Xiaomi does
Reg Samsung, that's my point: they indeed lie, it's not a 45W phone. Full stop.
I have two Super Fast Samsung 25 watt chargers. One for my S22U and One for my Tab S7+ and both can charge in under an hour. 45 watt chargeers just wasting your money, and extra wear on the battery for a tiny bit of improvement. Not worth it to me.
Hello, 4 days ago I bought this new s22 ultra with exynos processor, but it is generating many doubts that the loading of the device I feel that it is going very slow or more than it should be.
It always takes 2 1/2 hours or more to charge 100% with a 47w essenger charger or a Samsung charger that I have from the s10+ which I think is 20w and 3a
Measuring the charging speed in a plant or portable battery that I always have mark at most 20w but never stays at that speed, usually oscillates a lot between 10 and 16w, and stays much more at 10w which makes me weird and annoying because it is very low
I do not know if I should buy a Samsung charger of 25w since from what I have seen the 45w charge does not work, and that charger would be 5A unlike the one I have that is 3A but I do not know if it would make any difference.
I would like to know if it happens to someone else or if it is something normal, this makes me think a lot about changing phones since the charge seems to be very slow.
Please would appreciate any help, I will also leave attached the charging settings I have placed and the measurement I have made with my charger, I serve any advice you have please
Charges fine (inc. super fast) with Samsung charger ex Note 20
I have Samsung (i think 25w charger) and from 10% to 100% Max 1h10 mins

It's a QuickCharge 3. It's an old standard for Snapdragon phones and Samsung S-series before s20. To charge fast You need 45W PPS PD 3.0 charger. PPS is crucial.
If i remember correct samsung 45watt charging is 9v x 5A not 5v x 9A. If you have 3A the maximum you can charge is 27w (9v x 3A) but if your charger is 5v then only 15w (5v x 3A).
Exynos very fast charging battery and I tested 8 hours on TV Pingu

Turn off adaptive battery. It will change the charging speed for battery life savings. It's a new feature but has been making people think fast charging modes aren't working.
I have some Anker brand USB-A to USB-C charging cables and just the wall wart (is there a technical name for those things?) from something... probably one of my old Samsung phones... it says "Adaptive fast charging" and output says "9.0 V === 1.67A or 5.0 V === 2.0 A".
( know that stands for "volts" and "amps", but I don't understand what the rest of it means... 2 Amps is "faster" than 1.67 Amps... I think... but what makes it charge at one speed or the other?)
My real questions:
1) Will using the USB-A to USB-A cable that came WITH the Galaxy S22 Ultra make a difference in charging speed?
2) Do I need to get a different "wall wart"? If I want one that supports USB-C plugging into it, I do, but will it gain me anything?
Thanks.
Edit: I guess tehnically it's an "AC Adapter" or a "power supply brick"...?
See how what you have now performs. The best/fully compatible would be Samsung own charger. And any decent quality cables
I use my original charger from my Samsung Galaxy Note 4 on my S22 ultra. It charges it about 90 minutes. I suspect this is the same charger as yours.
1.67amps x 9v is 15.03watts.
5.00apms x 5v is 10.00watts.
15 Watts is a nice steady rate to be charging your battery at.
45w...is really too fast if you want your battery to last more than 2 years.

45W is nothing and won't really degrade your battery much. Also, keep in mind, that batteries degrade regardless if you use them or not, they have a shelf life. So, in 2-3 years you will mostly need to replace your battery anyway if you plan to keep your phone for that long (assuming that you want the battery to be at it's "full" capacity after 2-3 years).

Even still...I'll keep slow charging my phone...knowing that it will last 5 years.
My note 4 battery outlasted the actual phone. The touch screen packed up first. The battery still lasted 6 hours screen on.
I replaced it with a Note 9. Again...the battery was fine...and original. Same story...6 hours of screen on time.
Now I have a Note 22....or S22 Ultra.
I have used the Note 4's charger for all of these phones...with my 10watt Kosee wireless charger. Even on the Note 4...with a wireless adapter.

It's still 10 Amperes into the battery.
I'm often running ~10 Amperes into my dual 224 Ampere-hour 6 Volt "golf cart" batteries.
They also weigh about 130 pounds more than your battery!

It doesn't push 10 Amperes into the battery.
PPS charging is pushing from 3.3V to 20 Volts at 2.25Amps, it's dynamic charging and it depends on the device's state (temperature of the battery, the charger, the capacity of the battery).
I'm not sure where you get this information, and not trying to be rude now but maybe you should check up on both PD and PPS charging protocols that Samsung uses before assuming it's charging at 10 amps.

I have some Anker brand USB-A to USB-C charging cables and just the wall wart (is there a technical name for those things?) from something... probably one of my old Samsung phones... it says "Adaptive fast charging" and output says "9.0 V === 1.67A or 5.0 V === 2.0 A".
( know that stands for "volts" and "amps", but I don't understand what the rest of it means... 2 Amps is "faster" than 1.67 Amps... I think... but what makes it charge at one speed or the other?)
My real questions:
1) Will using the USB-A to USB-A cable that came WITH the Galaxy S22 Ultra make a difference in charging speed?
2) Do I need to get a different "wall wart"? If I want one that supports USB-C plugging into it, I do, but will it gain me anything?
Thanks.
Edit: I guess tehnically it's an "AC Adapter" or a "power supply brick"...?

1. With Galaxy S22 there is an USB-C to USB-C cable not USB-A (maybe a typo on your side). That cable is rated for the full power charge the device supports, that is 45w. It can make a difference if you are using it with a proper charger (that's the actual naming for the "wall wart"...it is called "charger" or "wall charger" btw).
2. Yes, you should get a different one if you wanna charge faster. Your actual charger is a (so called) "fast" charger with the charging power varying from 15W to 10W. Your phone supports from 25W up to 45W, that are the "ultra fast" chargers.
I'd suggest to get at least a 25W charger, also there are some extremely good Anker alternatives (even better that original Samsung chargers), look for Nano II 635 or 615 Anker chargers.
If you wanna keep your phone for an extended period (like 4-5 years or more), you might wanna activate that battery protection charge that only charges it till 85% and will preserve it for a longer period. If you switch phones after 2, even 3 years, don't bother, charge it as you like fast or slow till 100%

If the charger is rated at 45 Watts and sometimes actually delivers that:
45 Watts / (maximum) 4.3 Volt battery > 10 Amperes
Maybe they are PWM-ing it or whatever, but the peak current is > 10 Amperes.
Ok, we can subtract the efficiency of the buck converter, but it's still in that neighborhood.
What would happen if I bought and used a 65-watt charger? Would it automatically drop down to 45 watts to charge my S22 Ultra? Could it damage it, etc.?

1.Q. Yes.
2.Q. It not gonna damage it if not pushed to full 100% or discharged completely before connecting.
Sorry to hijack this thread, but is there a decent wireless charger, that will give me fast wireless charging with a Spigen powerarc arcstation pro 65w charger? I have tried about 3-4 cheap crap ones, and they all give reg wireless charging of about 22% for an hour's charge.
The S22U‘s maximum wireless charging rate is only 15 watts. I use the Spigen PowerArc ArcField 15 watt wireless charger, which is powered by a conventional charger via USB C cable and works very well charging my S22U.
