Question Superfast charging + emark cables -- are they needed? - Samsung Galaxy Tab S8

So I have a 45W charger, thinking about purchasing a 65W charger. I know The Tab S8 Plus only goes to 45W.
My question: are there any advantages to using an emark enabled cable?
I'm getting super fast charge notice with a 60W cable, no emark.
In my google searches, someone mentioned you can get "super fact charging 2.0" if you use an emark cable. Other pages said you only need emark above 60W. I found this comment on one site "... the Samsung Note 10+ or S20 Ultra which supports 45W fast charging. With these devices, the maximum electrical current is 4A, therefore it also requires a 5A cable with E-Mark. "
Does anyone know the ins and outs of this?
Thanks,
Joe

Get the recommended Samsung OEM brick and use the cable that comes with it. For the N10+ the 25w brick/cable fast charges fine and lasts for years if you don't roll up the cable.
Charging issues are hard to troubleshoot and non OEM bricks/cables only add to that burden.
At $20 a pop the 25w brick/cable is a no brainer.

So I have managed to answer my own question:
With a normal 3.1A US0b-C to USB-C cable, my 45W power supply is throttled back to 25W. It is reported as "Superfast Charge" mode by the tablet. Using Ampere, it reports that the battery is being charged at 5A at 4.2V --~ 21W
I bought a 100W E-Mark cable, and it now reports "Superfast Charge 2.0" -- and now Ampere reports it has bumped up to 7.5A at 4.36 V. So it is bumped up to 32W. Still not seeing 45W, though.
So it would seem to be charging 50% faster with the new cable.

I ues this combo for my s8+:
Anker PowerPort III 65W
Anker PowerLine III-Flow
It gives me 28W which is plenty fast for me. I can also use same charger for all of my devices, my laptop included

No Quick Charge 2.0/3.0 support

TurboPower charger that comes with it is the only thing that will give it a fast charge.
I have no idea how or why Quick Charge tech was left out.
Mine does indeed say "TurboPower Connected" and charges super-fast when I use the USB C Quick Charge 3.0 AUKEY Amp Type-C Dual-Port Wall Charger and the USB C Quick Charge 3.0 AUKEY Car Charger with Dual AiPower Ports. I can't seem to find it now, but I remember reading somewhere that the Moto Z does use QC 3.0, otherwise I wouldn't have bought the above products. NOTE: I am going USB-C to USB-C.
Does not use 3.0.
http://forum.xda-developers.com/z-force/help/moto-z-forces-turbopower-quickcharge-t3429607
In short QC 2.0 and 3.0 don't follow usb c spec according to a top Google engineer. According to Usb c spec the vbus voltage should not exceed 5v. QC tech exceeds this by using 9v and 12v to achieve more power. Motorola built the Moto Z according to spec which allows you to ramp up the current (amps) to achieve more power which is why our stock charger outputs at 5.7amps. You don't need QC to charge fast with Usb c. Usb c with power delivery is actually better . Either way the QC chargers put out 15 watts total. Our turbo charger does 28.5 watts using 5v at 5.7 amps and is actually faster than what's out now. QC chargers use higher voltage to achieve this at 9v 1.7 amps 15 watts, a charger doing 5v 3a does the same 15 watts. So to turbo charge your phone don't use QC chargers unless it also outputs at least 5v at 3a that's the key. Anything less than 3a won't turbo charge. It needs to be a usb C to usb C cable so the charger should have a usb C port not a usb a port like most of you are trying to use. No other charger out now does more than 3amps besides the turbo charger until then use chargers that do 5v 3a. Verizon has a fast charger that supports this and all other fast charging tech.

Will these charge as fast as the stock charger out of the box? And with a USB C cable does it need to support quick charge, or do all USB C cables support quick charge as long as you have it plugged into a USB C quick charge adapter like you linked to?
Nothing charges as fast as the stock charger as far as I know.
I looked around on Amazon to try to find a spare charger with the same speed as the OEM, but there are none as far as I know. QC actually goes against usb-c standard, so whoever has a phone that supports both is technically being shorted on charge speed. I will be waiting for the verified brands (ex. Anker/Aukey) to release a legitimate charger because there have been instances where wall chargers have completely destroyed devices. For the fastest charge, you'll want usb-c cables end to end, but since usb-c is not the standard yet, I would be very careful when buying lesser-known usb-c accessories. Z owners will have to wait for the market to catch up at this point.
Total side note but I wonder if the problems Samsung is having is because of their bastardized quick charge/type setup.
I'm happy we don't have QC.

I bought the Choetech charger from amazon and it works great on my Z Force. no where near the OEM charger but still charges the phone dead to full in a little over an hour and a half. from my limited testing.

The car charger that Verizon sells turbo charges the phone, but not as quickly as the stock home charger. I don't think any charger will charge as fast as the stock home charger, since it's optimized for the phone. But the Verizon USB-C charger charges the phone plenty fast.

I can confirm this. I just got this phone on an upgrade after insisting to the Verizon sales representative that I did NOT want a Galaxy S8, that I was absolutely sure I didn't want the S8, and that I think the Z Force is a much better device than the S8. After seeing the genuine shock on his face that I slighted his phone, I bought the OtterBox case and the Verizon branded USB-C car charger with it.
The car charger definitely charges faster than my non quick charge USB-C cable, but not as fast as the stock charger. The stock charger will take me from ~5% to full in an hour. The Verizon car charger takes about an hour and twenty minutes to go from ~5% to full.
All in all, it was worth the money spent on the charger. It is definitely better than the 8 hour charge my standard USB-C usually takes.

Anyone found a Power Bank that charges the Ultra at high speed?

Been looking for one for a while and purchased a RavPower 60w PD power bank but only to find it charges the phone only at 18w speed.
I assume the 60w PD is for laptops rather than this phone perhaps? Did notice that Xiaomi has a 20000 mah 3 Pro power bank which supports 45w PD charging but could that also be the same where it will support laptop charging at those speeds but not the Mi 10 Ultra.
Rather than keep buying different ones to test, would appreciate if anyone has had any success with a brand that charges higher speed than 18w?
You need PD/PPS not just PD. You can also try looking for a GaN charger if those exist. People say wall GaN chargers work.
Also, if you can find a qc4/5 bank somehow, those charge faster than that 18w which is I think just qc3.0. I believe the ultra supports up to qc5

Question Can we charge S21U with 40W chargers?

Hi to all,
Can we charge S21U with 40W chargers? They are a lot chargers like Huawei, Xiaomi and etc... with 40W and more.
I believe the answer is yes - or at least probably. Most of those newer chargers are "Smart" in that they only provide the volts and amps that are needed by the device being charged. I may be wrong about that, but I don't think so - I don't think you have anything to worry about.

Pretty sure you can, I use a 45 watt "smart" charger on my NOTE 20 Ultra without any issue.
You can use any charger that supports PD (power delivery), AFC or QC2.0
Any 45 watt USBC charger out there is going to be PD standard so you'll be fine.
The downside is, it'll still only charge at 25 watts.
I am charging my s21U with an 40w charger, works without problem. not using 40 watts of course, but its working.
The phone, all phones in fact, will ONLY charge at it's highest speed the phone allows itself to receive, the charger doesn't matter, it can be lower or higher than what the device is recommended for. A lower power charger will just take longer to charge the phone, a higher power charger will just not charge at it's full power if the phone won't accept the full power from the charger.
I've been using the 90w charger from my HP Spectre X360 my S20 Ultra since I got it without a single issue, I still get about 2 days of use per charge on that thing, and now I've been using the same laptop charger on the S21 Ultra and it works just fine.
The phone fast charges normally, doesn't get super hot, works just fine, and I only need to keep laptop chargers around the house, it's great haha
I have a 45W USB-C PD port as part of an Anker PowerPort and also the 18W charger that came with my Pixel 5. Would I notice much of an improvement in charging speed or integrity/longevity of the battery by purchasing Samsung's 25W charger?

That's the charger I've been using w/ S21Ultra (25W from N10+) and I figured out I won't be needing anything bigger then that. Thanks to Samsung 'super fast charging' the 5Ah battery on s21U charges faster then 3.8mA Pixel 4a5G battery(with the same charger). +/- 1 hour and done!

Question adaptors other than stock to charge rapidly

I have noticed that my stockpile of "fast" chargers I have acquired and used with my LG G8 do not enable the "charging rapidly" notification I get on the Pixel 5a.
Do I need to purchase a new set of USB-PD chargers for car & a/c outlet in order to achieve the fastest charging.
My current quick charge 3.0 adaptors make this phone say "charging" and not "rapidly"

Probably. If your current chargers don't support PD then you won't charge at max speeds. And if your current chargers are using USB-a, meaning you need a USB-a to USB-c cable you're definitely not fast charging.
I can recommend Anker products. The Nano pro is a sweet tiny charger.
Anker's PowerIQ vs Quick Charge vs Power Delivery: What are the differences? - Dignited
With a lot of competiting charging standards, It's quite hard to choose what's best for your device. PowerIQ, Quick Charge and USB PD are the most popular choices today
www.dignited.com
I have anker products already however they are using the older type-A connection. its a shame that google will only allow rapid charging via USB-PD spec and not the older QC-QC3.0 spec.
anker car chargers that support PD are not cheap either but I guess I should future proof myself
Considering that the 5a is only capable of charging at a maximum of 18W (9Vx2A) I am pretty sure the USB-A to USB-C cable will work, if you can find a PD charger that uses USB-A. The reality is that you will probably need to buy a PD car charger, and a USB-C to USB-C cable. I'm in the same boat. There are quite a few options, with PD and QC and 2.1A/2.4A USB charging all in a single charger, on Amazon and the usual suspects. I think the real disappointment is that the 5a only charges at 18W. The upside is that the phone not only has a huge battery but it has adaptive charging so will slow charge overnight - fast charging being bad for battery life.
You should look for a USB-C "charging" cable. Charging cables have larger wires for lower loss in the cable, but also are often USB 2 speeds for data, which is fine for dedicated charging use. It is also possible to find USB 3 charging cables. There are a number of different USB-C cables out there, including special ones with an IC to support Thunderbolt. Be sure to mark the capability of each one you buy. It is a bit of a mess.
Quick Charge works well but is not strictly consistent with the USB spec (although it does not interfere with USB operation). IIRC QC uses analog voltage levels on the signal lines to control the supply voltage. IIUC PD uses a digital handshake. I for one have been happy with QC but am glad to move to PD for phone and eventually laptop and tablet. Recent announcements extend PD from today's 100W max up to 240W max.
Android 12 looks to have tweaked Pixel Adaptive Charging so phones reach 100% closer to alarm
Pixel users have had hit or miss experiences with Adaptive Charging, and Google now looks to have tweaked how it works on Android 12...
9to5google.com
this article explains a lot. I have been using adaptive charging for the "slow" overnight on my 2nd day of use since the battery has so much capacity. I woke up the other night because of a thunderstorm and noticed my phone was already at 100% 5 hours before my alarm was set to go off. Another night I woke up to use the bathroom, around 3 hours after I had went to sleep and plugged in phone, verified it said adaptive initially and now it said rapidly! Why would a phone switch to rapidly charging in the middle of the night. I might just dig out an OLD slow charger brick from the basement cave to prevent this overnight mystery from a gimmick feature.
Will post back when I acquire a car charger capable of "rapid" charging which 18w seems plenty fast to me for most road trips.

I actually have a car charger that triggers the 'Charging rapidly' notification. I would link to it at Amazon, but I bought over a year ago and it appears they no longer have that item in their stock. You need to make sure on those that they have a USB-C port on them labeled "PD3.0" or I believe that makes them incompatible. The search term I used there was

usb c car charger pd 3.0 21w
The 5a uses a USB-PD 2.0 charge protocol, not PD 3.0. Any USB-PD charger should work, as there were very few v1 devices ever made. When buying a car charger I recommend a charger with at least two ports: a PD charge port (USB-C) and a QC charge port (USB-A). The latest ones will support PD 2/3, PD 3 PPS, and QC 4 (and even 4+ and 5) on the USB-C port, and QC 2/3 plus several other protocols with the USB-A port. That pretty much covers the great majority of smart phones. I just bought a three port (2xUSB-C, 1xUSB-A) car charger. The USB-C ports are identical except that one is 30W (for phones) and the other is 100W (for laptops and tablets, or another phone). Note that increasingly new devices are requiring the PD 3.0 PPS, and there are fewer chargers available that support that. Also, higher power charging requires a special cable with a supporting IC inside so I ordered the package that included charger and cable.

I'm returning to Texas Thursday from an international business trip; will order one when I get back.
Thanks,
Joe
I purchased it and have been playing with it.
1) It is small. Fit in the palm of you hand small. Easy slip into a pocket while travelling small. Similar form factor to the old Samsung lightning chargers -- they are rectangular while it is square, but similar volume.
2) I don't see that it is faster than my existing 65W PD/PPS. Both give a max of 7.2A @ 4.1V -- but it could be cable limited. I have three supposed 100W / 5A cables. If you add 1A for the discharging load (Ampere reports 1A is discharging when unplugged), it's providing ~ 34W. But that's using Ampere which tells me what the state of the battery is, not what the actual current/voltage from the power supply is.
Overall, I'm a little real-life disappointed that I don't seem to be seeing 45W charging, but think it is worth the $30. If you have 30 min between flights, it can definitely top off an empty tablet battery.
Take care,
Joe
So I've been on several flights with this small charger. It is now my go-to for travel. What I like is that it charges the tablet so fast I don't feel bad disconnecting and charging my phone or ear buds for awhile. It only takes a few minutes to top up the tablet battery back to full. And no problem running on 240V power.
