Samsung Exynos' faster charging tech vs. Qualcomm's QuickCharge 2.0

Is anyone aware of what is this new charging standard Samsung is using for allowing 4 hours of battery in 10 mins charge?
It's definitely faster than Qualcomm's QuickCharge 2.0 but I'm not able to find any details on the specific name or tech details and I'm certain it's not a regular charger. I'm hoping to buy a few spares of these types of chargers so if anyone can provide details on this that would be great!
UPDATE: Answer confirmed! http://forum.xda-developers.com/showpost.php?p=59794206&postcount=9

honestly it's really nothing more than higher flow of electricity flowing through the USB adapter at 2A @ 9 volts ~ and a combination of higher capacity battery charge rate internally to handle the extra voltage.
i can probably get 4 hours on my S4 which also has a rapid charger, with only a 10-15 min charge... also, it's not really 4 hrs they mean of actual usage.. they probably mean that the device will have extra standby (light usage) for up to 4 hours with only 10 minutes charge., not that you will get 4 hours screen time in only 10 min charge time.
edit: it'll be a USB charger like this, which IIRC is similar to the one in the note 4 that supports the same quick charge:

Hmm...if higher amps and voltage is it then I'm curious to know exactly what those specs are. 2A @ 9 volts is that confirmed? If that's the case then just a higher amp QuickCharge 2.0 charger should be enough I'm guessing since we know it supports 9 volts along with the standard 5 volts as well.
And of course I know that "up to 4 hours usage" is to be taken with the best case scenario as usual (standby time) but nevertheless they did claim multiple times very cleary that they have the fastest charging solution on the market (counting QuickCharge 2.0 which has been out for a while so no way they can't be accounting for that I hope).
I'm reading here about this charger:
http://www.samsung.com/us/mobile/cell-phones-accessories/EP-TA20JWEUSTA
This Samsung charger has an output of 2 Amp to give your phone power at a much faster rate than your typical 1 Amp or 700mAh charger.

Pretty standard stuff so far, there are plenty of 2 Amp chargers out there already.
Additionally, it comes packed with Adaptive Fast Charging technology that will charge Samsung devices with that feature built-in at an even faster rate!

Do we know if that "Adaptive Fast Charging technology" is just extra voltages (like 9 and 12 volts) just like Qualcomm's basically? Or is it truly unique to Samsung devices that other devices can't take advantage of?

According to this looks like that's right. It's just an additional 9 volts (missing the third 12 volts like other Qualcomm QuickCharge 2.0 chargers).
http://www.amazon.com/Samsung-Adaptive-Charging-EP-TA20JWE-Universal/dp/B00PIZ5JB2/
Output/Sortie:
9.0V--1.67 A or 5.0V--2.0A

So if we got this right then as long as we have any QuickCharge 2.0 charger it should work the same way with Samsung's AFC technology.
(assuming there's no security chip preventing otherwise - Samsung has done similar things in the past)

yes, they should technically be compatible with each other. you''ll also be able to use the S6 charger on say another device that is only rated at 5V, that's basically what adaptive means,. 5 or 9V. or whatever else the charger is rated for.

Is it that you need this smart & security fast-charge cable ?

I tested a generic QUALCOMM 2.0 charger with an Samsug s 6 and worked with no warnings and provided message that 'fast charger' was being used

Samsung's own website does mention something about Quick Charge 2.0, which means that they're probably using Qcomm power management ICs.

Looks like the stock Galaxy S6 Edge AFC adapter is just 5v and 9v like all QC 2.0 chargers are. That's good to know that any QC 2.0 charger should work as a great spare as well. :good:

A 2600mAh lithium battery (@3.8v) should be 9.88Wh.
This charger can charge at [email protected] == 10 Watts, or [email protected] == 15 Watts.
Charging at maximum wattage for the Samsung charger would be charging at about 1.5C. Battery experts used to recommend not charging faster than 1C (at least as far as the wealth of information on the Battery University site goes), but I guess they've made advancements in the longevity of lithium these days.
Assuming the quick charge specs listed are measuring the part of the curve that can charge at maximum wattage, 15 Watts for 10 minutes is 2.5 Watts / 3.8v == 658mAh, or about 1/4 of the battery capacity.
The "100% in an hour" (I've seen that in press releases, but couldn't find that figure on Samsung's web site) is exactly 1C over all, but since lithium batteries are charged on a curve it will likely be charging at this 15 Watts for only part of its time on the charger and then drop down even below 1C for the last part until it is 100%. It would be interesting to see if it can get a full 50% in 20 minutes or if it can only do full charge for about 25% of the capacity in the best case scenario part of the curve. Also, over what range of initial SoC is the 25% still valid? It's doubtful it can charge that fast if it starts at 75% because the biggest cutbacks in charging tend to be on the "full" end of the scale. I believe that charging circuits will tend to also "take things slowly" when starting near 0%, but 10-35% should be doable, possibly 25-50%. Now if only I had an hour with nothing to do but stare at a phone's battery percentage and record figures...

So basically this car charger http://www.amazon.com/gp/product/B00D82O68Y/ should charge my s6 edge as fast as possibile right??
And there's no need to buy a "qualcomm 2.0 quick charge" car charger because it would just" adapt" to the power requirement of the s6, correct?

the 1C rule no longer applies. it's been years since that was the general rule. i run alot of different batteries for my hobbies and i charge some of them upwards of 3 - 4C.
imo, quick charge, fast charge, or whatever they want to call it, is just mostly marketing. the battery do charge slightly faster, but not much faster than at 5v @ 2A. my S4 can go from 5% to 50% in about 30 minutes, yet it's not "quick charge" just the 5v @ 2A.
in my opinion, i would much rather charge without using quick charge on an S6 because for that 5-10min faster charge it might offer, it'll just put unnecessary wear on the battery. considering that the s6 has no removable battery and if you plan to keep your device long-term (say upwards of 2 years) then id avoid using quick charge all together, including wireless charging which creates even more battery wear (more heat).
i do believe charge speed is slightly less important than charging capacity, so i don't even plan to always charge my s6 to 100%. li-ion battery will last longer if they are kept under 4.10v. might gain an extra 200 cycles by not maxing out the battery all the time.
if the battery were easy to swap, i wouldn't care, but i plan to have the phone for at least 2 years so i want to retain max life from the internal battery, hence why i dont care much for quick charge. getting to 50% battery 10 mins quicker is minor to me so ill be sticking to normal 5V charger.

I don't know enough details about how Quick Charge works to be able to answer this. The device looks like it always supplies 5v, but up to 4.8A to yield 24 watts. It also doesn't distinguish if it is actually a 12w+12w charger or if either side can draw the full 24 watts. Does the S6 fast charge off of 5v, or does it require the 9v output to do its magic? The Amazon listing does list the S6 and S6 Edge in its description so "maybe". If it simply supplied 5v and the S6 decided to only draw 2A from a 5v charger then you may not get as fast of a charge (10 watt vs 15 watt) compared to a charger that claimed Quick Charge 2.0 compatibility and might supply 9v.

Do you guys know if there are apps that prevent to charge up to 100%?
Lets say where you can set a max of 90%.

Tasker can notify you when it reaches 90%, maybe. No app can stop the phone from charging, though.

You need a charger that has - Qualcomm® Quick Charge 2.0 Technology
not one that says - PowerIQ Technology
Hope that helps

Something is Fishy
I've tested the S6 Edge with Multiple Chargers (my lady has the S6 Edge too). When I use my Samsung Charger at 20% Battery it says 3hrs 10min to full. When I use the charger that came with my LG G2, it says 1hr 30min to full. Seems like Samsung went cheap. I tried her charger too, different outlets, even at a different house. Fast Charger my butt

Samsung and Intel are using the Qualcomm tech with some slight modifications which can be done without paying royalties leaving the only truly different technology to Oppo. The spec requires an embedded controller on the SOC and the associated circuitry which allows the device (phone in this case) to control the charge coming from the charger. The quick charge tech works the fastest with (mostly) depleted batteries which can take more juice more quickly and is less effective with battery topping where the battery cant accept charge as quickly without overheating.
I've read a couple people saying they had non functioning chargers out of the box, I would try someones quick charger known to work ctrlaltdelete and see if that isn't the case with you. You should get much faster charging, The Oppo charger will not work with our devices but all the QC 2.0 chargers I have tried do work at the same speed as the supplied charger on my Edge. It's impossible for a functioning quick charge charger to need 3 hrs to charge this phone. The math simply wont allow it.

Just wanted to ask a quick question , which one charges faster the adaptive fast charging or quick charge 2.0 ?

LG G4, stock battery, quick charging 2.0 and AUKEY charger, is it a safe match?

Hi, I've recently bought a LG G4 and this certified 2.0 charger:

...it's still boxed and I've also found a thread here in XDA sayin it doesn't work on G4. For some reasons. I still haven't tested it. Yet the reviews of LG G4 owners on Amazon of this particular charger are all very positive.
ANYWAY
Prior to the LG G4 release I read a few articles that talked about a certain 3300mA battery that was Quick Charge 2.0 compatible.
This puzzles me.
THE QUESTION:
Do I need such 3300mA battery or a QuickCharge 2.0 special battery to *safely* quick charge my LG G4, or is the stock 3000mA battery ok?
(OPTIONAL QUESTIONS)
1) Is it going to damage my phone/battery in some way? Will the battery life get shorter? Will it overheat causing the phone/battery any damage?
2) How is it possible that a Qualcomm Quick Charge 2.0 certified charger does not work with the G4?
3) Could you suggest me a trusted, working charger, possibly under 15 euros?
Thanks for your time!

I think when you get people to say it doesn't work, doesn't mean it won't charge. It means that you won't get the additional benefit of quickcharge 2.0. AFAIK, the phone will still charge at higher amp (5V 1.8A), but will not charge at the QC 2.0 (9V 2A) standard.

Thanks for your answer. I still don't know what to think because LG-G4 owners' reviews on Amazon are all positive and satisfied with the increased charging speed.
What about the main question?

I use the same exact charger on my G4. It's great.
1. No damage, and your battery life won't be any shorter than regular charging. The QC is set to slow down after 60%, if I'm not mistaken.
2. Don't know who told you that it wouldn't work with the G4..
3. Who says you have to pay a lot for quality? It's a charger..

1. I heard 75% myself but either way it slows down.
2. The G4 seems to be finicky to what QC2.0 charger it wants to work with. There are reports of it not working with the aukey and reports of it working with the aukey.
3. Cheap crappy chargers can actually cause harm. If it's QC2.0 certified there's no problem.

I got [phone was off] 30% after 20 minutes
55% after 40 minutes
75% after 1 hour
then took 40 minutes for the remaining 25%, 10 minutes the last 5 percent alone.
Is QC2.0 working? I haven't ever measured normal charge percentages. It was a little bit hot in the first hour, then it cooled down.
I used the USB cable shipped with the AUKEY charger since the instructions say "please use the included cable for your non-iOS device" or something like that.
Should I keep using it or using the original G4 cable will make a difference?
Could you please suggest me a good (possibly cheap) QC2.0 certified charger from another brand that has a more... constant behaviour with the G4?
Thanks for your time

several days ago, i buy aukey multiport QC 2.0. From my experience, QC 2.0 does not give any advantage to G4, compare to original charger. It's need 102 minute from 5% to 100%. Stock charger need 105 minute from 5% to 100%. claim that's QC 2.0 will charge 60% for 30 minute, not proven using aukey. When i test using usb voltage and current tester, aukey using 9V. So i'm curious, is really G4 is qualcomm QC 2.0 compatible ? Yes, it's can use 9V for charging, but not get advantage charging 60% for 30 minute, and not much different from stock charging that only using 5V.
Something make me curious to, why other charger with more than 2A output, needed about 3hour (or more), compare to G4 stock charging (1.8A). Is this stok charging made spesial for fast charging too ? and G4 cannot get advantage from other charger, although it's have more than 2A output ?

My genuine Samsung fast adaptive charger charges my G4 about 20%+ faster. May be an Aukey problem.

I don't think aukey is the problem. It can charge at 9v, than regular 5v. But it not make it more faster than stock charger.
But for Samsung charger, yes, it can charged faster than stock charger, according to my mailing list friend. I'm not try using it yet, just order another QC 2.0 charger. LVSun 4 port charger, can be use for desktop or car charger.

I bought this one http://www.amazon.com/gp/product/B00ZZG6IKU?psc=1&redirect=true&ref_=oh_aui_detailpage_o03_s00
and it does not appear to charge any faster than regular car charger i had before. Ampere+ reports 1375mA or so

I heard that LG G Flex2, G4, is compatible with the Quick Charge 2.0 tech. If the phone is compatible, it is safe to charge it with a quick charger. And my friend use the Aukey 10000mAh Portable fast charger to charge his iphone. He says the charger works well and I wanna try it.

I just bought a Tronsmart Quick Charge charger and it charged from 15% to 100% in about 1:15 hours while a Samsung 2.1A charger (the one that came with my S4) charges it in 4 hours from 10% to 100%

If it slow down it's useless, I need to charged my phone before I leave home, like I have 80% because I used it during morning, but before leave home I need 100%...

So I just charged my phone with the original charger for the first time and it is actually giving me Quick Charge 2.0 speeds. From 27% to 67% in 40 minutes which translates to 1% every minute.

AUKEY Fast Charger ... Works great
I have the Aukey Pa-T1 5 Port Qualcomm 2.0 Certified Charger. It does charge faster than stock LG Charger. Generally, it seems to charge 1% or more per minute but slows down after about 80% charged. I have been using the LG Stock 3000ma batteries with the charger. Aukey guarantees that the charger will not harm the battery or phone. There is a special circuit inside the charger to regulate proper charging. The only way this charger won't work correctly is if you have a knockoff battery or cheap cable.

I have aukey 3 port usb quick charge and it is much faster than original LG one. Almost 3 times faster!

Could you check with an app like Ampere and compare numbers to the included wall charger? I'm guessing it's 2.4A and not the full 3A. Still faster than 2A at least but not the full potential.

Interesting. The Tronsmart for them gave only 1.8A but could be because it was done at a higher battery percentage.
And I'm willing to bet that at very low battery (5-15%) the stock charger does 3A.

This nexus 5x car charger is the best on the market right now, one of the few quick chargers for this phone. I thinks its a MUST accessory to have for this phone

Could you check with an app like Ampere and compare numbers to the included wall charger? I'm guessing it's 2.4A and not the full 3A. Still faster than 2A at least but not the full potential.

I just got my phone and I'm merely topping off the battery, but Ampere first gives an error in inability to gauge battery charge then asked to switch modes... then it only shows around 1A for the OEM charger. So not sure we are gonna get good reading from that app. I guess it's possible that the amps tapper off when the battery gets close to full, but there seems to be better testing involved here.

I believe I saw a video or read an article that explains that all fast charging tech basically works the same. The more empty the battery the greater the charge. As it gets full it'll be less. So topping off and only getting 1A could be right.

Full disclosure, @Tronsmart provided me a unit in exchange for an unbiased review. I've been using this charger for a few days on my Nexus 6 and have to say I'm very happy with it. I have a few Quick Charge 2.0 devices but also have a Nexus 5X and 6P on the way, so I wanted something that could handle any device. The Quick Charge port delivers, rapidly charging my Nexus 6 without any issue. The included 1m cable is very thick, as is the fixed Type C cable. My Nexus 5X showed up today, and officially it will not charge as quickly as the included 5V/3A charger the phones come with as this tops out at 5V/2.4A. That said, the fixed Type C cable registered as "rapidly charging" so while it may not be quite as fast as the 15W wall charger it's delivering enough power for the phone to indicate rapid charge. I'm very happy with this car charger since it offers both the old and new options until Type C becomes more ubiquitous.

Have you got the 6p? my bro's order still pending. If you get the 6P, please also test if it will rapid charging it, and show us some photos.
It's helpful to hear your review.

Glad it helped, no 6p yet. I'm still pending too

Can someone tell me if this would work for rapid charge?

For that price, you may as well try it. I will say though, the cable you use could make the difference and then there may be a handshake issue for it to get a full 3a charge. I think it is still very much unknown which type of car charger can provide the full 3a until they get tested. My guess is that you will need a true USB-C type that is also rated for at least 3a.

First review on Amazon is:
Cheap
Blew up (sparked, smoked), without even having anything plugged into it. Used it once.
There are a couple other reviews that say it doesn't charge at 3A.
I'd steer clear, but that's just me.

check the price here will definetely get one today!

Anyone read this?
http://www.techtimes.com/articles/9...-chip-and-a-soldered-usb-type-c-connector.htm
"The Nexus 5X currently does not have a Quick Charge feature. However, this teardown attests it is equipped with the ability to support the feature in the future, since it houses the Qualcomm SMB1358, Quick Charge 2.0 IC. Given the fact the 5X's USB-Type C connector is supported by Qualcomm, a possibility exists that this feature could soon be activated for the device."
Is that true? How to activate the quick charge 2.0 on Nexus 5x? can't wait for this, developer!!!!!

When I used the AmazonBasics Charger (2 USB ports, claiming up to 2A each) with an A to C cable my 5X says 'Charging Rapidly'. (Apologies for no links - new user account)
I haven't tried it with Ampere yet - I wasn't expecting it to say that at all, I was just looking to keep things topped off during my commute this morning.

Mailman just delivered the Tronsmart. Seems well built. It's odd that they chose to hardwire the cable to the charger rather than putting a female USB C port on the charger and then including a USB C double ended cable.

Quick Charger 4.0 wall charger

Hi guys, anyone here are using QC 4.0? If yes, can you tell me where to buy one good?
I'm looking for QC 4.0 in chinese sites, but it's hard find there,

You could try the official Razer phone charger. That has QC 4

I saw the Razer Charger, but found in on site only, like 40 eu.
I can't find any good review with QC 4.0, they are all QC3.0 and i don't know why :/
any clue?

i had a QC4+ adapter some weeks ago bought from amazon
https://www.amazon.de/helpers-lab-L...F8&qid=1538499272&sr=1-2&keywords=helpers+lab
there is absolutely no difference between QC4+ and a normal QC3.0 adapter.
I've send back the QC4+ adapter, by the way, Power Delivery 3.0 is 100% compatible with QuickCharge 4+. I've a power delivery powerbank and they can charge my phone on the same speed as a QC3.0 or QC4+ charger. I have compared all adapters and there is no advantage of Quick Charge 4+
With QC4+ adapter the phone charge on maximum 3300 mah ~17w
this is the same i get with my QC3.0 adapter and my PowerDelivery Powerbank.

It's not just speed that improves with each version, it's also efficiency. Less power drawn to charge at the same speed = less heat.

Good that you say that....
I forgot to mention that the QC4+ charger getting very hot in both situations, in IDLE and when Charging a phone. You can read the same phenomenon in feedbacks of the charger I mentioned from Amazon.
I stay with it, IT IS NOT WORTH the money you've to spend for a QC4.0+ charger, there is absolutely NO Advantage to buy it. I've tested for myself and this is just my opinion.
and as i said, its more useful to buy a PowerDelivery 3.0 charger instead a QC4+ charger because PD is 100% compatible with QC.
Here is some info about it:
Quick Charge or Power Delivery
It seems that PD can deliver a much higher power output, but actually most smartphones do not need more than 18w charging, that’s why Qualcomm’s Quick Charge is widely adopted by most of smartphones, while Power Delivery as a standard that anyone can use is more designed for larger devices like laptops and household appliances.
What’s more, Qualcomm announced Quick Charge 4.0 in 2016 which is compatible with Power Delivery. In other words, Quick Charge 4.0 has simply learned to speak PD language, but still does the same thing as Quick Charge 3.0 with a few upgrades.

No, but I read a lot and understand, that qc4 + support PD 3.0 and it give maximum 2800mA and charges by 2 channels. And we have fast charging with 12 v and 1.5A = 18 W, thats why we have no hot battery. With qc 3.0 we have 3700mA, thats why we have hot battery. And Miui qc logo appears with 3000mA and higher. Conclusion - QC 4+ works with PD technology

Can you try after updating to 10.3.1.0? I did and now PD charging is also marked as quick charge (text and lightning icon too). Using a (hopefully) PD3.0 capabke charger (Blitzwolf BW-PL4 45W). I also has a Baseus QC4.0+/PD3.0 car charger, but I can't figure out which protocol is working as the phone is compatible with both and only the Type-C port of the charger provides both.

Thank you guys. This is almost identical to my 18W QC3.0 and 45W PD3.0 charger (tops at 3400mA).

According to this gtrusted article,
The Xiaomi 18W QC 3.0 Charger supports the same power profiles of 15 watts (5 volts @ 3 amps), 18 watts (9 volts @ 2 amps) and 18 watts (12 volts @ 1.5 amps),
[...] with its battery fully discharged, we could see charging initially went up to around 16.7 watts (6.2 volts @ 2.7 amps) which later dropped slightly to about 15.4 watts. The current pulled continued to decrease along a 5 volts rail towards the end of charging to eventually settle close to zero when the battery was almost full
Click to expand...
Click to collapse
However, if using a PowerDerlivery 3.0 charger, we could benefit from Mi 8 support of 27 watts (9 volts @ 3 amps), and 27 watts (12 volts @ 2.25 amps) for charging.
I am after am AUKEY charger that is capable of switching between those voltages, which is called PDO. And according to that it is possible to charge 50% battery in 30 minutes.
Our Mi 8 phone has been tested to support this PDO profiles:
7.5w (5V - 1.5A)
15w (5V - 3A)
27w (9V - 3A)
27w (12V - 2.25A)
As such: QC4+ = PD3.0 + PPS + QC3.0

Question 100w same as 25w?

do you know what is happening here?

I don't have any information to illuminate what's going on, but this sounds familiar enough that I think at least one or two other users in this section have reported something similar. Me, I try not to quick/fast charge any more than I have to, and I keep my battery between 25 and 75%, so I don't pay that close attention.

I haven't used Ampere. I assume the top is the charging current? The one on the left shows a higher current, 5.58 amps, vs 4.40 amps. Higher current for a given voltage means more power is being transferred, thus a higher charge rate...but even 5 amps is pretty high. That's why fast charging schemes use higher voltages, because a given conductor can usually handle a higher voltage better than it can handle a higher current.

The Galaxy S8 is advertised to be able to charge at a 45 watt rate, max, so if this is true, a 100w charger wouldn't charge any faster as both devices would negotiate a max of 45 watts. This is assuming both the device and the charger limit the charge current; I imagine many devices will draw more power than they're rated, and many chargers will try to supply it, although the load might pull the voltage down.

Probably because your tablet can't charge at a rate any higher than 45W - 15v @ 3 amps.

That is correct it can only take 45w so 100w won't work. It will only limit the 100w charger down to 45w

You shouldn't look up what a USB port can take. It also depends on what main board and battery can take. In this case s8 ultra is limited to max 45w. So your 100w charger won't go 100w on this tablet because it does not support it.

the charge circuits are limited to a max input wattage and voltage. to protect the device from being burnt out. it is not like the good old days where you could pump as many watts and volts you wanted into a device hoping that you didn't burn it up, blow the fuse or a diode. now everything is limited to a max input. a lot of it has to do with the brand x / universal chargers being sold. that claim they charger faster when really they don't.

The question is not about 100w
it is about 100w doing 45w vs 25w charger and same time charging

I don't know. They're both charging at about 5 amps which is honestly pretty high. Nothing indicates the actual charging rate in watts because it doesn't display the charger voltage. I will say I'm rather skeptical of strange off brand Chinese tech so it's possible you'd get better results with a different charger.

Question is neither is showing super fast charging 2.0

Fast charging is on in settings. It shows super fast charging but not 2.0

I got the same issue with my s22 ultra...The charger must have the right specs and the cable must be 5a. If not, you won't get super fast charging 2.0. This will only give 25w fast charging. I have a 65w ugreen charger that has all the right specs...It has 65w max on 1 port and when other devices are connected on the other ports it distributes the 65w over the ports. I used the cable that came with the tabs s8 ultra and got the same as you, not charging to it's full potential. Bought a ugreen 5a cable and now it shows super fast charging 2.0 on my tab s8 ultra and s22 ultra. The charger and the usb cable must be 100 % correct, otherwise you won't get max charging speeds.

The cable makes absolutely no difference in the actual charge rate. Being rated for higher current just means the conductors are larger.
When you connect the device to the charger, the two negotiate a mutual rate.

Superfast charging + emark cables -- are they needed?

forum.xda-developers.com
If you have a normal 5A cable, all PD charges are throttled to 25W (or less). Your tablet (at best) will show "Super fast Charge" and you will see something like 5A @ 4.12V when running Ampere. This is the power going into the battery -- the PD Charger is probably delivering something like 4A @ 5V. Around 20W going into the battery. I assume the "missing" 5W is powering the tablet - i.e. Ampere only shows what is going into the battery.
To get more than 25W, you need special "e-mark" chipped cables. These allow current higher than 5A to be delivered. They will be generally be rated by power -- 100W -- not current. I use

This will allow the PD charger to run higher than 25W and you will see "Super Fast Charging 2.0" for charge status.
When I use the 100W cable, the tablet charges iin "Super Fast Charging 2.0" mode, and Ampere tells me the battery is receiving 7A @ 4.12V, or ~ 30W. Because I'm using the tablet at the same time I again assume some additional power is going to powering the tablet -- but that Ampere is only showing what is going into the battery. So maybe this bumps it up to 35W total. I have 45W and 65W power delivery bricks, so I assume the ~ 35W-ish delivery is being controlled by the tablet.
Note: The cable "in the box" with my Tab S8+ was NOT chipped, and was limited to 25W.
take care,

Please see
Superfast charging + emark cables -- are they needed?
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...

If you have a normal 5A cable, all PD charges are throttled to 25W (or less). Your tablet (at best) will show "Super fast Charge" and you will see something like 5A @ 4.12V when running Ampere.
