So I picked up my S8 yesterday, and those stories that came out a week or so ago about needing the new $90(USD) Samsung Fast Wireless Charger in order to fast-charge wirelessly were true!
I have that Samsung fast-charge wireless charger from last year (the one that came out with the Note 7) (https://www.amazon.ca/Genuine-Samsu...2614821&sr=8-10&keywords=samsung+fast+charger) and it doesn't fast charge my stupid phone!
And before you guys ask, yes, it is plugged into a fast charge brick (the one that came with the phone). And I *do* have wireless fast charging turned on on the S8. It's hidden in a weird spot in the settings, but it's there.
I tried it with a flat charger that I picked up on Amazon (https://www.amazon.ca/gp/product/B01N8RGTJV/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1) only because it was USB-C, and that one fast-charges it. Not sure why the one Samsung released 6 months ago doesn't do it.
Are you using a different cable than what came with the charger? I've noticed that sometimes the cable can affect the charging rate of the wireless charger (noticed it with the fast charging stand I just got after using it with my S7E).

The Samsung fast charging stand didn't come with its own cable (here in Canada, at least) - so there's no correct cable to use. And I can't use the cable that came with my S8 because that's USB-C. I'm using a plain old anker USB-A to Micro cable.

Honestly, that may be your issue. Do you have any other cables you could use? You could also buy an oem galaxy s7 cable. Again, I had plugged in my fast charger using a cable that I use to charge my wireless mouse, and it wouldn't fast charge, but using the cable that came with the charger or the original s7 cable does let it fast charge.

Thanks for the suggestion - I'll troubleshoot the issue. Don't have a lot of micro-USB cables laying around these days, but enough that I can try to isolate that as a cause if possible.
@KWoods41
Did you use the fast wireless charger from the Note 7 / S7 with one of these devices before?
I have a non original one
(same design as here - https://www.amazon.ca/Genuine-Samsu...2614821&sr=8-10&keywords=samsung+fast+charger).
I have two of them one does turn on/of repeatly for about half a minute then carges the S8 with normal wireless charing (5W). The other charges the S8 from the beginning with fast wireless charging (10W). Bothe same cable and QC 2.0 Wallplug)
But keep in mind that one of them had these problem from beginning even with my S7.
If you use the included USB-C to Micro-USB adapter of the S8 and plug this on the cabel that goes into your old (S7) wirelles charger and then in your S8 does it charge fast then or normal?
The fast charger I have for my S7 Edge, fast charges my S8. It's the round, upright Samsung charger. It even says fast charging when I place it on the charger. I use the cable that came with my S7E connected to the charger.

No problems wireless fast charging here either. Same charger as I used with my S7, 1 year old or so. Got the stand one that accepts your standard micro usb. You gotta make sure you have the adaptive power wall outlet, decent usb cable (no adapters on it), and wireless fast charging enabled in settings (mine was off for some reason).
I have a fast wireless charger I used on my GS7 and it still works for my my S8. And yes it shows "fast wireless charging".

My generic fast wireless charger that worked with my S7 and Note7 does not fast wireless charge my S8+ - BUT I think the previous posts have merit to them. I think the issue is that I am using a 6ft Anker cable. I'm thinking either a shorter cable, or one of the original Samsung cables, should resolve the issue. Sucks though because I need a 6ft cable to reach the outlet...

No they weren't! I have three 2016 fast chargers and they all work the same way they did with my S7e. If anything I'd say the S8 seems to charge a bit faster on them.

Wow - you were dead right. I swapped that Anker or Aukey cable (don't remember which brand it was) for the micro-USB one that came with my Gear S3 and, lo and behold, I am fast wireless charging with my S8 on the 2016 Samsung charger! Thanks for the suggestion.
I'm not sure why this was an issue for the S8 but not the S7 edge or Note 7, but I don't care anymore!

I have a jelly comb fast wireless charger that worked perfectly on my s7edge with the original cable and power adapter.
It does not work with the s8, unless it is used with a crazy short cable or the non-fast charger from an LG tablet.
there is a setting to turn on wireless charging? where is this?
Mine works fine as well, original flat Samsung fast charge wireless pad. Both on my work S8 and my personal S8.
My off brand generic fast wireless charger works just fine.
Just took delivery of an Anker fast charging plate from Amazon and it works in fast charging mode on my Galaxy S8! Had previously tried two Samsung fast charge plates which didn't fast charge the S8 and an Aukey model which worked for 30 seconds then stopped. The Anker one is here. It looks really nice too and has LEDs which only light up when charging starts. My only concern is that it has no fan so will need to monitor how hot the phone gets. Great for a nightstand!

Is there anything special about the USB cable and wall charger that came with the Atrix 4g?
The cable isn't long enough and I need to find one that is at least 6'.
not at all. it's just a standard micro usb cable.
Beware of other phone chargers with mini usb though. The atrix is much more greedy than my wife's lg clamshell and it won't charge from that charger. It turns on but never actually charges.

The cable yes, the charger itself, no.
I got a generic one from [a national store] and it charges but locks up the phone while charging.
So apparently there are differences.
I've used the USB cable from an HTC, a Samsung, and a Blackberry. All worked fine. Take apart a cable and see what's inside of it - I think you'll find they're all the same.
Universal Serial Bus is a standard. In Europe that means that all USB wall chargers have to be more or less the same. I use an Amazon Kindle charger with my Atrix just fine. Have also previously used chargers from other Android devices, WP7 devices and Blackberries.
In short, you'll be fine.

well, yeah. you'll find it won't fit and won't charge if you're trying to use a mini usb cable.
Fair point, I did name the wrong connector. In my defense the USB guys do mess with their connector names and types all the time.
A charger with exactly the same plug (from an lg clamshell) failed to charge my atrix but did turn it on.

All proper chargers work fine on mine!
DON'T use cheap 1$ china chargers! They often have badly stabilized voltage and can even destroy your devices!
While on devices with proper stabilisation the voltage should look like the topmost graphic on this image (even under full load), on cheap devices it often looks like the one on the bottom, or something inbetween!
Also, some very cheap chargers allow the device to draw too much current, while grilling some internal components of the device. This could even start a fire!

For cables, you can use the cheapest! I never had a cable break in a way it could destroy anything besides itself, and I always buy cheap cables from www.dealextreme.com!
I can recommend this cable. Very solid build quality, better than most cables for 10€ around here!
Any of the usb wall chargers advertised for iPhones will work. I found an awesome one for my car by looking the in apple section at walmart.
I order nearly all cables from monoprice.com super duper cheap and they always work just fine. You can get a micro usb for less than a dollar.
I just use a chargers off monoprice. Super cheap adapter and cable.
My friend's galaxy charger fits, but does not charge properly. About 10% per hour.

Funny, my front-mounted USB ports (which put out just about 500mA) do a fine job for most devices including my Atrix. However, do not try to charge from dead via USB. For that you really need the full-power AC adapter. I use one from a previous phone at work (Samsung I think) and it charges in no time.
cable any micro USB cable will do. I have been using the cable that came with my kindle since I got the phone. The cable that came with my phone I think is in my car and the some random 3' cable in my bag for my computer. They all work fine. As for charging the computer and car USB is very slow as the only put out about 2.5 watts. The one that came with our phone puts out a little under 5 watts.
I always buy Monoprice cables. Although I have to admit the 1" micro usb cable I had been using from them seems to be broken as the cable will or will not charge depending on how its folded. But for the $1 or whatever I paid for it, it lasted a long time.

Almost forgot...I've been using the ipad wall charger. It's a 2amp charger and charges the phone extra fast. I've been meaning to look for car cigarette lighter to usb chargers that are intended for ipad so I can have that 2 amps available for any device.
Just for information.
I recently bought HTC Evo 3D for my wife and installed a self-made 5V/3A charger in her car. The charger converts 12V in-car to 5V/3A stable.
I immediately was stuck with a problem. Whenever I put her Evo 3D it charges nicely. But my Atrix don't.
I remembered there is something special in Atrix USB toward charging. I checked and found that adding 10K resistor between white (receive or transmit?) and red (+5V) wires let my Atrix charges as it should be.
10K resistor has no effect in HTC.
From what I know it is just a standard Micro USB, the usb to outlet adapter, I am not sure, but it looks like a fairly standard device.

Good to know I'm not the only one that has this problem, thought there was something wrong with my handset.
Is there a fix or work around to the slow charging issue? If I use the stock charger and cable that came with the DNA I am fine, but my OEM Thunderbolt charger (which looks the same) and my car charger I got from Amazon (which I understand may be a knock off but had worked before on the DNA) or any other charger give me a slow charging notification.
This is a pretty big deal for me since I use my phone a lot for work. If I am in the car my phone is not charging fast enough to keep up with drain from the navigation.
I am rooted, s-off, twrp, and running Viper ROM 1.2.0. I understand HTC implemented this "feature" with the latest update. I couldn't find any info about a fix so are people just dealing with it?

You can flash a kernel like crpalmers or zarboz's kernels with fast charging implemented. But what I recommend is buying a USB charger that wont have that issue.
Take your phone somewhere that they have a Nexus 7 or Asus tablet set up on display with the regular charger hooked up.
They sell the chargers lots of places, the Nexus 7 will be best both spec wise and it comes with a pretty nice micros USB cable but I see the transformer prime charger in more places to walk in and purchase retail brick and mortar.They're solid chargers that will deliver the power your phone will allow. You just have to be careful when using it when charging with fast charging enabled it gets warm because it's running that current through their. The OEM charger only runs about 70% of the rated current through there.
Best Buy has a RocketFish 12volt car charger micro USB with an extra USB slot for a second USB cable and device. I almost never use car chargers but I was actually impressed with the quality of this charger. Also HotTips makes a charger that's rated at 5.0 amps and I believe as long as it's not a cheap crumby USB cable it will work fine. A lot of times it's the cable itself not the charger, so I would try taking your USB cable from home to work and plugging it up to that same USB charging plug and see if you get the same slow charging icon.
Thanks for the thorough response. I tried to do some testing combining different cables and charges and the only one that consistently gives me slow charging is the car charger (which worked fine previously). I have a Transformer Prime charger and Droid Razr charger that both worked fine. My Thunderbolt charger worked when I tried this time but has given me the slow charging notification in the past.
I may have to pick up one of the car chargers you mentioned because that is the most important. My phone is running great otherwise with Viper ROM and the kernel that comes with it so I'd rather not change it.

I believe that forces fast charge when connected to a computer via usb. Some people have said it may fry your usb port but I don't know how true that is.
Android phones in general charge slower when connected via car charger.
this Motorola one here works fine:
http://www.amazon.com/gp/aw/d/B000S5Q9CA
or you could always get a power inverter and then use whatever cable you want.
Get the Verizon car charger. Works fine for me..

I ordered these cables from Amazon, got them today and I'm still getting slow charging from the car charger. These are really high quality and still not working. This is pretty ridiculous, HTC should have at least made this optional.
I posted on this a while back, its the cable that causes the issue. If you open up the cable and short the data wires it works perfect. All you needs is wire strippers, electrical tape and shrink tubing.

Thanks for the suggestion. The cables I bought are very high quality, charging specific cables, and I'm still getting slow charging in the car. If HTC only wants to support official OEM chargers that's fine, but then they need to make an official car charger!!
Also, why does HTC only support using the OEM charger when the DNA supports Qi charging? Doesn't make "Sense"

I tried that with the Rezound awhile back and afterwards it still registered as 'charging USB'(aka slow charging).
P.S. that Motorola charger I mentioned above, I opened one up before and noticed it just had the 2 power cables(black & white) and they were also much thicker then the standard cables w/ all 4 wires.
When I did my cable hacks I cut the cable in half, put a piece of shrink tubing on one end reconnected the power wires, shorted the data wires on both plugs. When you do this you cannot reconnect the data wires. They must be separated. I'll post some pics in a few to show you what I mean.

Basically this is what you want it to look like...connect the positive and negative, you can reconnect the shielding too. Also I highly recommend soldering the wires together. Adds strength.

You can do the cable hack shown in the post above as some non OEM chargers do not have the data wires shorted at the charger itself. You can either hack the cables, or if you need the cable for data, then modify your charger. Please make sure your charger is rated at least 800mA. Any charger rated 800mA or below will charge slow. Computer usb ports are rated 500mA and this is why it charges slow. My car's radio has a usb hook up and it also charges my phone at 500mA which is not enough if I'm calling, navigating, etc. The OEM charger is rated 1A. You can use a 2A charger as well but don't use it everyday. Higher rated chargers do charge the battery quicker, but at the expense of the long term battery life.
Sent from my HTC6435LVW using xda app-developers app
In my testing even shorting the chargers data pins on chargers seems to be more of a miss. I've done a few and even after shorting them they still state USB mode. It mainly stems from the data pins being present in the cable itself. Two of the chargers I shorted were for a vehicle and they were rated for 2.0 amps. Also if just charging the phone yes don't use high output chargers. But if charging in the car high output won't hurt if you are using navigation, music etc...it actually needs the higher output to charge hence needing to charge at the AC rate.

I have this issue as well now, I never had it till the update back in Feb. I used other Android phones on my car charger and they charge just fine and it only happens with my DNA. I think there is a firmware issue that is causing this to happen.
This afternoon I hacked a cable as shown above, to use with my car charger. I'm glad to report it worked like a champ and my phone went from slow car charging to very rapid charging.

Then I bought this http://www.amazon.com/Kensington-Po...05&sr=8-4&keywords=kensington+4.2+car+charger and for some reason one port shows up as AC charging and the other as USB. Its supposed to be two identical 2.1 amp ports, so why that is happening is beyond me.
Can someone please recommend an app that works well withe the Note 3 to measure current?
Can someone please recommend something that will actually work? I basically want a charger (for car) that can charge my Note3 and my wife's, at the same time, at least at the same speed my OEM charger that came with the phone does.
Does what cable I use make a difference at all?
Thank you for your time
I don't have the GN3, but a GN2. I have and use Ventev 4.2A rapid car charger. You may want to try it. It works well with my GN2. What's nice about it, both ports are 2.1A 5V. I was hoping it would charge my GN2 and ASUS Infinity Pad tablet at the same time, but the tablet needed 15V. Thus, it's end up being trickle charger for the tablet, but does slow down the battery drain.
And it's pretty cheap. Seems solidly build. I also have the wall charger unit and works well too. It may just do the trick.

I didn't look at your second link. I thought you were looking for suggestions on a charger that could charge two GN3 quickly. I'm still a bit annoyed with many andriod 10" tablets needing 15V to charge. I have car cigarette power inverter with a AC plug outlet and two USB ports (2.1 and 1.0) that I can use that will charge my tablet quickly.

There's also a Pro version for $0.99 as well. I use the free version and it works just fine, but there are ads, but that's expected from a "Lite" version of an app.
Thank you for the app recommendation. It has been helping. So here are some results.:
Using Kensington adapter, I get 350mah on both USB ports using a regular micro USB 2.0 cheapo cable I picked up at Frys for 2 bucks. Using another cheapo cable but this time 3.0, I get 1200 mah in one port and 450 in another.

Try using OEM cables or at least high quality 3rd party cables. I ran into an issue with note 2 where my third party cables only charged at 250mah. When I got a replacement it jumped up drastically. Also car will be different than house wall outlet. Compare both.

I had the same problem at first. Then looking at others forums and checking out my own phone I realized that the phone only charges at 1200mah while the screen is on no matter what chargers or cables you use. When the screen is off then is charges at 1800mah like normal. Samsung built this into the phone and I have no idea why..

When I had my issues I ended up averaging 1800 mAH on an oem. I used the Galaxy Charging Lite app as well. (Edit: just realizedthat's what you used too)
Just in case, you may wanna try another app. Usually the apps just measure the input based on what software tells them so there is a bit of inaccuracy but not enough to be way wrong. Truest test is an amperage meter or something like that. But 1800 on Wall adapter sounds right bad on a micro usb (2.0), I haven't tested usb 3.0 but it should be higher I would think.

I had the same problem at first. Then looking at others forums and checking out my own phone I realized that the phone only charges at 1200mah while the screen is on no matter what chargers or cables you use. When the screen is off then is charges at 1800mah like normal. Samsung built this into the phone and I have no idea why.. I have noticed that the Y-CHARGE 4.2 Dual USB Car Charger charges two devices at 2.1amps each. I've tested both ports and they are good. http://www.tylt.com/y-charge-4-2/ Thats the link. Check it out. Hope it helps.

Just to be sure, you tested both ports using a note 3 and you actually got 2100mah readings in the app?

This is my limited understanding that comes from researching this myself....
USB has 4 pins that our phones care about. The 5v+, 5V-, Data + and Data -. The 5V pins charge the phone. The Data pins tell the phone what rate to charge at. I believe it is specifically the voltage the phone senses on the data pins. There are some DIY mods out there to use resisters to change this and force a higher or lower charge rate. Those mods were a bit out of my comfort zone so I just skimmed them.
Also, Apple and Android do this differently in some way and most high voltage chargers have iphone and android specific ports because of this (whether they are labeled or not). The Anker car charger I got does this. I don't know of a reliable high amp car charger that has two "android" specific ports. I have tested the Android specific port and it seems to charge at the same rate as the wall charger that came with the phone. I will try and make time to test the "iphone" specific port on my Anker charger to see what mah I get and if there really is an appreciable difference.

If it is not too much trouble, can you download the galaxy current lite app and tell me how many mah you are getting in your house charger and how many mah you are getting in your Anker Android port? Also, I'm assuming you got a Note 3?

The app will tell you 1200 if your screen is on - after is been plugged in, make sure your screen is turned off, then quickly pull up the app after you turn your screen on and it will show 1800

Here's what I've been using. Great so far. http://www.amazon.com/dp/B00GANTT94/ref=cm_sw_r_udp_awd_HsY3sb034XV0R
I bought a dual outlet 4.2amp charger at big lots (got 4 of them actually on sale $10 a pop) that is 2.1 amps per outlet. I use samsung cables with it and my note 3 charges are full speed no problem.
I would just bypass all this and get an inverter for the car and run the OEM charger... takes out all the guesswork and charges exactly the way you are expecting.
Example... turns your cars 12vDC into 120vAC

Hi, where to buy original Xiaomi Mi 9 Wireless Charger?
Is there a good offer? Maybe with a normal Charger QC4.0?
Thank you

I bought mine from AliExpress.
I too ordered mine from AliExpress - with the 27W wall plug bundle
https://www.aliexpress.com/item/Ori...381.html?spm=a2g0s.9042311.0.0.12f44c4dJnoFeC
Question: did you buy the bundle (~30 euros) or just the wireless charger? (~20 euros)
I wonder if I can use the stock 18W charger to power the wireless charger and still get the 20W wireless charging...
Does anyone know if you need a specific power adapter to use the wireless charger?

How do you want to get 20W on the wireless pad using a 18W socket?? If you use the 18W adapter you will just limit the pad to 18w too.
You must buy the bundle (27w power adapter + 20w pad). You can use the 27W adapter directly using usb cable to get full dash charge, or use it on the 20w wireless pad

Because there are watts, amperes and volts.
I just read the product description and saw that:
Input: 12 Vdc, 1.35 A or 20 V, 1.35 A for QuickCharge
Given that the charger that comes with Mi 9 (MDY-08-EI) delivers a max of 12V / 1.5A, the answer to my question is no, it won't work - not at max quick charge capacity at least.
Hard to see point of wireless charger really. Seems to me its better to have a cord, you can use the phone lol . On the wireless charger, phone have to sits there.
I like wireless in the car for example.

Agreed, though I must admit I've grown quite fond on my wireless charging stand next to my bed for night time. Just nice to simply place it down and pick it up, bypassing the need to plug or unplug!
It's the simple things in life eh lol

that's why order with adapter from ali for just 10$ extra. Otherwise it's a turd. Try find standalone QC4+ cable charger for this price locally. Worth it.
Your performance is ok, 18W QC2+ chargers were always used to power up 'fast charge' wireless stations in order to produce such output (10W).
in order to product 20W wireless, you need not 20W adapter, but 27W QC4+ adapter as there's lot of loss.
Wireless chargers (i have all types):
*5W: require basic hispeed charger (rated usually 5Vx2A=10W)
*7.5W: iphone stuff, who cares, requires QC2+ charger (18W)
*10W: requires QC2+ charger (18W)
*15W: forgotten generation (although some Huawei customs exist), remember people were waiting for samsungs to upgrade the speed for years but since S7 nothing happened
*20W: upcoming generation, requires QC4+ charger (27W), hope it will be official qualcomm format so we can use the charger for another devices..so far it's not specified in Qi
If you are thinking to use the pad next to your bed..... Don't.... The fan is making a lot of noise...

I have this one:
https://www.amazon.co.uk/gp/aw/d/B07KG5HDFX?psc=1&ref=ppx_pop_mob_b_pd_title
It's not fast as such, but I really don't mind. I pop it on when going to sleep and wake up fully charged, so fulfills it's purpose! Plus I like the stand more than just a pad (and it's silent )

That's a bummer... I had hoped to replace the good old cabled phone setup besides the pillow...
I'm really interested on buying the wireless car charger, but haven't seem that available at a fair price so far...
I can only find twice of Xiaomi's MSRP...

Made the mistake and bought only the wireless charging pad without the plug and cable :/... is there any cheap and good separate plug and cable available?
Same here, I just bought the pad, I thought it would come with the charger (different from the 27W) or at least I thought I could use the original Mi9 charger
I found only plug deal here. :highfive:

Cheers, kind sir!
has anyone received this yet and tried it out?
saw this but wanted to know how loud it is when in use: youtube.com/watch?v=gvXSAGuS1PU&lc=z22uu3xbswmlthudjacdp431dzjsvg5gjw53i03sje5w03c010c
I'm using the official one since a few days, it's fast, but the phone get hot and a quiet fan is running sometimes.
I know there don't seem to be a lot of 3rd party chargers that are capable of "Super Fast Charging" on the S20, but just wanted to drop a quick note that I found one.
I travel (well usually..) a bit, and try to consolidate my chargers a bit so I'm always on the lookout for decent multi-port adapters. As everyone knows, there are a ton of high powered adapters out there that you would hope give us the juice, but if you have read a bit - Samsung not only requires a PD port, but also PPS - and there aren't a whole of lot of adapters that support them.
I was hoping to pick a new adapter up to try and keep my Surface Go and S20 Ultra charged up, and not be a huge brick and came across this 65W 3-port bad boy: https://amzn.to/2L5d2uf from a company called Baseus. I have a couple of cables from them and they also seem to be popular on Aliepxress as well as Amazon, so decided to give it a try.
Got it in last night and paired it with a new USB 3.1 Gen 2 100W cable that I also just picked up, and lo and behold - I plugged that sucker in and "SUPER FAST CHARGING 2.0" popped up on the screen when using the top USB - C port.
Interestingly enough the second power only registered "SUPER FAST CHARGING" (no 2.0) and the USB-A QC port registered as "FAST CHARGING." Reading through the documentation it's because the first port can give the whole 65W, the second tops at 30W, and of course USB-A is limited. I guess that makes sense since Super Fast 2.0 is 45W with the Samsung OEM charger.
Bottom line, if you are looking for a 3rd party multiport that supports the max charging on the S20 (and I assume Note 10) - this one does the trick. I got mine on Amazon (they had US stock so came relatively quick) - but if you are willing to wait, can probably pick it up on Aliexpress or other source for cheaper.
I bought it for my laptop 4 months ago now its the only charger I use .

Nice! -- my primary use was for my Surface, and I didn't think I'd get the highest charge with the S20U, but was a pleasant surprise.
I got an Ugreen USB C Charger 36W with 2 Type C ports that works as a Super Fast Charger

You can use any PPS PD charger like baseus 65W on aliexpress but super fast 2 will not be real.
Many chargers trigger Super Fast Charging 2.0 but before You will celebrate, please run battery charging monitor from play store. It will draw a charging curve. Almost all non samsung chargers will oscilate. You wil see around 6000ma and after 2-3s it will drop to 500, and again and again.
This can damage your device, and will take a long time to charge

Thanks for the heads up. I ran the app for a few minutes on the BaseUS charger and didn't see any of the dramatic dips as you mentioned above - so I'm hoping that's a good thing. Looks like a pretty consistent curve.

The charging current you are getting is not Super Fast Charging 2.0 even though it says so in your notification bar. This is mine with Super Fast Charging 2.0 using the Samsung charger and cable. Battery Charging Monitor will report a higher charging current.
Also wanted to add that the Xiaomi Powerbank 3 Pro with USB PD will charge the S20 Ultra at Super Fast Charging 2.0 and at 5A with the supplied samsung cable. And aftermarket Baseus USB C cable only gives 3A.

Interesting -- well, I guess my takeaway is that it isn't TRUE 2.0 super fast - but also it hopefully won't fry my battery! (i.e. not as fast as I'd like, but at least not going to damage the battery).

I tried my test with a couple of 100W-rated USB 3.1 gen 2 cables - so it definitely wasn't the cables. But goes to show that cables are an important part of the equation too!
SFC 2.0 require e-marked cables to work, as well as compatible pps charger.
IMHO the best option is to get 45w samsung charger. Other brands are hit or miss.
