I bought this hdmi cable from amazon: http://www.amazon.com/gp/product/B00K61OB6C/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1
I hooked up the tab to the tv, cranked up netflix and nothing. I plugged in the power adapter and got a picture. So needs charger to plugged in to work. I wasn't real keen on the output, but was only testing for connectivity. Might come back and edit after I have chance to adjust settings.
Today, I plugged the cable into the second hdmi port on my tv and it does mirror the tab display. Good response time too.
The charger is necessary but it does not charge the Tab. Left it plugged in and battery was down to 38% before i noticed.
Maybe a hardware error? Because under features it's described that it will charge your device...

Probably not a hardware error. I'm on my 3rd dongle that's supposed to charge your tablet while using connected devices. The latest is this one: http://www.amazon.com/E-More%C2%AE-Multi-functional-Connection-Reader-Samsung/dp/B00K80C9CE/ref=sr_1_8?ie=UTF8&qid=1403104007&sr=8-8&keywords=HDTV+HDMI+Adapter+Cable+USB+OTG+Card+Reader
Everything works except for charging the tablet. Have a red X on the charging symbol while the battery continues to drain. It does charge the tablet while it's off. I have a power hungry Tab Pro 12.2 that has trouble maintaining a charge while playing a couple games with the stock 2 amp charger. I'm beginning to think that none of the HDMI dongles out there are capable of delivering the current necessary to run the larger tablets.
Ah, I see. It's because not enough power through the micro usb. You need 2A but this adapter's only delivering 1A.
It seems, there a no adapters with 2A...
I have a ton of usb chargers gathered over the years. Largest i have is only 5.1 volts. Tab has a large output. Wonder if other devices could be damaged using it or is output regulated by draw of whatever it is attached to? At any rate, i don't think any of the dongles or otg cables have a power source other than what is supplied by the tabs adapter. So are you thinking it is an issue with the pin configuration on the adapter? It is a 11 pin connector. Sure wish there was 1 standard for everyone instead of everyone having their own.
Sent from my LG-D959 using XDA Premium 4 mobile app
It's not limitated by the pins, there are just for more or less possibilities for an interchange (at least a salesman told me that). It's limited by the inside electronical components. Maybe anybody out there to explain it better or correct my words?
If I remember correctly (it's been a couple years since I tested it), my S3 required the Samsung charger + Samsung wire hooked up to the HDMI (I have the Samsung HDMI adapter) to charge the device while mirroring the screen. I tried it with a more powerful power adapter (2.1 amps vs Samsung 1.x amps) and generic wire but the phone would lose power over time. I could even charge the phone while mirroring if I used a generic Samsung wall charger and Samsung cord that was listed as 0.8 amps.
I bought the official Samsung one a few weeks ago and it is working fine, it also charges the device while using it but you have to connect a charger to the MHL-HDMI adapter.
Sadly I recently flashed CM11 on my TabPRO 10.1 and now the adapter doesn't work anymore. I get picture but no sound Was so happy about getting CM11 official on my device, but this feature is something I can't live without so I'm going to have to hop back to stockbased
HDMI doesn´t work
Hi guys! I´ve bought this one adapter dhgate.com/product/1-1-mhl-11-pin-micro-usb-to-hdmi-cable-hdtv/163941539 I know is not the original one but doesnt work!!!! I did all the steps but nothing. Any idea?? I have installed the original ROM on my galaxy tab t520. I need help!!! Thanks
Hey everyone, so just reading all the comments regarding the HDMI adapter not charging your tab while it is plugged in with the charger, I have also had issues with it and also with my Note2 and the Samsung Smart Dock I use with it. But I did however manage to find the solution to why it would not charge while on the HDMI dock that is connected to my T.V. It seams that if you plug either the Smart Dock or even the HDMI connectors to the HDMI cable first then plug in the charger it will show its charging but will eventually lose charge while outputting an HDMI output, instead, you need to first plug in the charger cable into your HDMI adapter, then plug it into your phone or tablet and finally plug in the HDMI cable into the adapter, I have found this to be the way to keep my phone and tablet charging while also having the HDMI output connected to my T.V..
Hope this helps .
When I connect my LG L90 D410 phone with Android 5.0.1 to charging with the travel power adapter (output: 5.0V) that came with the phone, it charges fine most of the time, sometimes it heats up the phone. Also when I connect the phone to my car charger, the phone heats up quickly every time.
However, the heating does not happen when it is connected to my laptop high or low powered USB 2.0 ports.
So, I want to check the power output of the chargers that I use with my phone.
Please suggest if there is any app that can measure the power input the phone is getting from the charger that is connected to it.
Try out Ampere in the play store.
Hello,
I have found this comment about the cable :
Note: I tested PC mode with a USB Type-C to HDMI cable I bought on Amazon. Because the Mate 10 and Mate 10 Pro support USB 3.1 it’s technically possible that you can screen share to a monitor and charge the device at the same time. I asked Anker if a powered USB hub with HDMI support like this would work, but they said it depends on wiring and whether a hub has been designed to communicate with the Mate 10 or not. I also asked Huawei for clarification, and they have vowed to get back to me on the specifics of what to look out for in a compatible hub. I’ll update the review as more information comes in. Thanks to Bram Peeters for raising this issue.

Is there a HUAWEI reference for this cable ?
Does it need to be HDCP compatible, with Netflix eg ?
Best regards
Hi Pascal... I already tried the desktop mode. Technically any type-c to hdmi adapter should work. I'm using this: https://www.incipio.com/chargers/usb-c/usb-c-digital-av-multiport-adapter.html ... and I added an HDMI to VGA cable adapter because there's a VGA cabled monitor at home that's not in use.
My current setup:
** Mate 10
** Incipio 3-port AV adapter
++ Logitech 2 in 1 wireless combo (keyboard and mouse using 1 usb dongle) attached to the 3-port adapter
++ Charger attached to the type-c port
** HDMI to VGA adapter
** monitor
Works without any issues except that the charger cannot push enough power to actually charge the phone. It still drops so probably from 80% you have a good 2 hours average of desktop mode time to perform stuff. I am thinking of getting a DELL type-c to hdmi adapter (just a simple hdmi adapter no extra ports) for playing games.
I got myself a Macbook usb 3.1 dongle ( Lmao ) and i can't seem to push power fast enough to charge my phone, it helps though, having power in drains the battery slower than having no power in

In fact, few months ago, i was looking for a USB C HUB (With or not HDMI, Ethernet) with power delivery,
for an ACER SWITCH V10 (2017), to connect many external USB HDD and KEYS.
I have found many products on Amazon.
And these products (USB C HUB) like EgoIggo HUB USB C (GN30E) on Amazon, could be fully adapted
with a Mate 10 PRO. Some of them are too Mac OS X or/and Windows compatible, with or not drivers.
Look the description :
[Multi-operation] 3 USB 3.0 ports, 2 Card Readers for SD and micro SD, 1 HDMI Slot, 1 RJ45 Eternet Port and 1 USB Type-C Charging Port. Compatible with new devices equipped with a Type-C USB port.
[High transfer speed] With a data rate of up to 5 Gbps, the three USB 3.0 ports allow you to connect your keyboard, mouse, USB flash drive and external hard drive to the laptop. An SD player and a micro SD player support SD / SDHC / SDXC cards up to 2 TB. An HDMI slot that supports resolutions up to 4K. An RJ45 Ethernet port allows a super-fast internet network up to 1Gbits / s, but also backwards compatible with 10 / 100Mbps
[Unique Design] This Hub is very small and thin, but robust, whose connection cable is properly flexible, which makes the connection very stable. This elegant aluminum-shaped design perfectly matches the style and color of MackBook and MackBook Pro.
[Power Delivery] USB-C Power Delivery (PD) for Macbook Macmini and other USB-C devices, capable of simultaneously transferring data and charging devices.
[Ultra Portable] This hub is packed with a small box of cardboard and well protected by a nice cover that prevents it from scratching your mackbook. Incredibly compact size and very practical to carry everywhere.
Best regards

same concern with the incipio that I'm currently using.
From what I see, it will just drain the battery however we use it. Probably faster if we use the same adapter as Pascal's find. If I have the chance I will test Huawei's adapters (they have a different brand of adapter here in the Philippines) - I can try and borrow: see if it CAN push the power enough to charge the phone. But I'm already assuming that it won't.
Given the fact that the type-c port provides 100% of what it's supposed to run on desktop mode, powering the adapter.. powering whatever usb device is plugged in, that power requirement is the one that needs to be addressed.
But overall not bad for a phone especially when you can still use the phone while working on desktop mode. We can't do work on the phone of course but just enough to get a few things done with a screen and keyboard/mouse combo...
Well according to some German website it's stated that the Mate 10 is Compatible with USB [email protected]*2A so we might need to get a USB PD compatible charger to hopefully gain more juice than using draining the battery slowly

probably if we use an adapter with a type-c slot going to the type-c port of the hdmi/type-c adapter....
I was looking at the Tronsmart multiport charger I think. It has a type-c port so you can use a type-c to type-c cable... BUT it only pushes out as fast charge on the mate 9... so of course that's also a fast charge on the mate 10... BUT again, that's if we plug the phone directly to the charger... would that be a different case if we plug it to the hdmi adapter? I'm actually planning to buy it.. just so I have a multiport adapter especially when out and about. This one says Power Delivery.. probably I'll grab this thing by end of the month and the type-c end to end cable...
http://www.tronsmart.com/products/tronsmart-u5p-60w-usb-pd-desktop-charger-with-voltiq
hopefully I can report back as soon as I get it.
current dilemma is we have a super charge adapter... and yet it's not pushing enough juice... hopefully the type-c type-c scenario works so we won't have draining issues...
***** UPDATE *****
CORRECTION ON THE BRAND...
I was referring to Anker and yes the idea for Power Delivery appears to work.
https://www.anker.com/products/variant/PowerPort%2B-5-Ports-USB-C-/A2053111
Still using my desktop mode original setup:
Mate 10 - Incipio 3-port adapter (type-c/hdmi/regular usb) - hdmi to vga adapter (vga cable LED monitor) - TYPE-C to TYPE-C cable going to the new Anker desktop charger (type-c port is Power Delivery capable) ....

Baseus O HUB Type-C multi-function converter Adapter
Hi, I'm using a mate 10 and I've just bought a Baseus O HUB Type-C multi-function converter Adapter (HDMI + Type-c charging port + USB3.0). Can't seems to get it to work (PC mode or mirror) when connected to HDMI (tried on Panasonic LED TV & Toshiba projector).
Wireless mouse and keyboard working and phone is charging when I've plug in the charger to the hub. Is there any setting that I've missed?
Regarding Desktop mode: I bought an adapter and successfully connected my mate 10 to an HD TV, but the resolution is low, does it depend on the TV, the cable, the adapter or there is a way to set the desktop mode resolution? I haven't found it ...

so standard Mate 10 Pro charger (which says fast charging when plugged into phone) doesnt fast charge the phone when connected to the USB Hub. But youre saying if i buy this Anker charger my phone will fast charge when connected to a USB hub?
What is the exact spec of that Anker charger that makes it different to the Huawei charger in the box? Sorry for confusion, thanks in advance.

Anker desktop charger that I'm using: https://www.anker.com/products/variant/PowerPort%2B-5-Ports-USB-C-/A2053111
It has Power Delivery - which powers most usb-c devices nowadays especially Macs and other Google devices if I got that correct.
The description has this:
USB Type-C, Premium 5-Port 60W USB Wall Charger with Power Delivery for Apple MacBook, Nexus 5X / 6P and PowerIQ for iPhone, iPad, Samsung & More
The stock charger will definitely work without problems IF DIRECTLY attached to the phone but this time we have an external device - the multi-port hdmi/type-c/usb adapter. Yes it has a type-c port included and you can attach the stock charger but from my experience especially with the Incipio adapter, it requires more "push" because the stock charger just slows down the drain when using desktop mode. It does not increase the phone's battery juice while in use.
:angel:
** Also, Huawei stock supercharger adapter pushes 22.5W of power BUT ONLY if connected directly to phone. Power delivery pushes 29W of power REGARDLESS of which device it's connected to. The Huawei charger is also picky so it might not be using all 22.5W if connected to an in-between adapter.

hi, thanks for your detailed reply. the edit with the wattage is especially useful. one last question. Does the Anker charger "fast-charge" the huawei mate 10 pro when connected directly? or just standard usb charging?
If yes, i will replace my huawei official charger with this anker one. handy that it has some usb ports as well so i can charge my bicycle lights overnight etc as well
thanks in advance for the further information

that's one of the things I actually was surprised with and didn't really expect...really good news for us because it does!! The phone registers FAST CHARGING even if I have "everything" connected for desktop mode.
* phone + incipio type-c hdmi usb combo
* incipio + hdmi-vga converter
* vga converter + vga led monitor
* Anker multi-port with type-c power delivery + anker type-c to type-c cord ..... connected to the incipio
** and a recent addition: since the incipio only has 1 regular USB port, I bought a 4-port usb hub... connected it to the incipio so that basically splits 1 into 4 usb ports... I attached my wireless keyboard/mouse combo and my Western Digital 1 Terabyte external HDD...... NO PROBLEMS WHATSOEVER.... haha!.. phone still chargers UP with fast charging indication...
Now I guess I have a full working desktop system with the mate 10
(I'm using the regular mate 10 but I guess that shouldn't affect the charge input/output)

Just an FYI to others, the Huawei Mate 10 Pro has 3 different charging modes. One is USB Charging, very very slow. One is Fast charging, like regular charging i guess. SuperCharging is really really fast. This Anker charger only fast charges my device.
I cant get SuperCharge unless I use the Huawei official charger or the Huawei AP09S PowerBank.
How can I SuperCharge with 3rd party accessories?!

To understand the chargin technologies one must understand how Watts Volts and Ampere work. Volt x Ampere = Watt. Explaining Volt and Ampere is kinda long story but to keep it short: Imagine a garden hose: The pressure of the water is Volt, the speed of the water is Ampere. Watt is the amount of water thats pouring out.
There are various technologies for charging, in the end it matter how many Watts there are. But different combinations of Volts and Ampere are possible to achieve the same amount of Watts.
There is a new universal standard called Power Delivery which was introduced with USB 3.1 Type C. So this is a standard that comes with usb 3.1 type c and that is why all the new usb3.1 type c laptops support it. (PD supports multiple protocols (combinations of V and A to reach up to 100W) and the more powerful ones mostly support the lower ones too. that means a 100W PD charging brick could charge a 5Vx3A=15W Phone, a 14Vx2A=28W iPad Pro, a 60W Macbook, an 80W Ultrabook etc.)
Previous Charging standards are something around 5V and 1A,2A, computer usb 2.0 ports only give 0.5A and usb3.0 ports give 1A, which is why some laptops have a dedicated phone charging port that delivers 2A (most phones used 5V/2A before fast charging technologies hit the market, it is also the protocol phones fall back to if the charging brick does not support the fast charging technology of the phones manufacturer)
Phone manufacturers have their own technoligies or license them from other companies. Qualcom has QuickCharge which many smartphones use (Samsung uses QuickCharge 2.0 with 9V and 1,67A (Delivers roughly 15W))
Huawei has its own SuperCharge which is based on 5V/4A and 4,5V/5A (delivers around 22W). So in order to use supercharge you have to get a charging brick that explicitely supports 4,5V/5A protocol and a cable that supports 5A (since standard USB 3.1 Type C Power Delivery protocols are based on a maximum of 3A most usb-c cables dont support 5A).
So as i mentioned before: more powerful charging bricks usually support less powerful protocols. so in order to charge devices that do not support the specific fast chargind protocol, all chargers also support 5V2A. Thats what happens if a Samsung is charged with huawei brick or my mate 10 pro is charged with the samsung brick (the difference being that Huawei seems to label the usb 3.0 pc port 5V/1A as "charging", the normal 5V/2A as fast charging and the Huawei SuperCharge at 4,5V/5A obviously is called SuperCharge). USB Power Delivery aims to end that by providing a standard that is available for all that use a 3.1 type c port. (that means if i have a 60W apple chargin brick for my macbook i can also use the same brick to charge my 29W ipad pro or another 60W usb type c ultrabook with windows with the same brick and cable without thinking twice. before usb type c and PD all laptops had to have dedicated chargers)

Hi enrico. I have exactly the same issue and it seems like its related to the 4K TV only. FHD TV work fine with my mate 10 pro but when I connect it to 4K TV it sticks to 640*480 resolution, which is useless obviously. Have you found a solution or anyone else ?

You getting much heat on the device I've used Samsung dex before and the S8 got warm but not very, I'm using the Mate 10 and the Dex hub which charges fast but phones gets quite hot using easy projection
So I have the stock charger, a rather generic charge cable, a generic hdmi cable, and an Insignia NS-PU378CHM Usb-c to three port HDMI /USB 3.0 /USB-C power
The problem: when I hook up hdmi and am running DeX on my TV, the battery drains. Even with external power connected.
So I measure the current the charger is delivering, and when using the hdmi adaptor, I'm getting about 1/2 an amp. When I plug power in directly to the tablet, I get a full amp. Battery drains faster than it charges when using the adapter.
I don't know if I need a better charger, to suuply more current under load, a better hdmi adapter / power adapter, a better power cable (but the fact the cable supplies twice the current when plugged in directly suggests it isn't the cable).
Does anyone have a combo they use that keeps power from draining when running dex on hdmi?
Or should I figure it is impossible to supply enough current to keep the battery charged at 100% when running hdmi / dex?
Thanks,
Joe

Check out this link https://forum.xda-developers.com/ga...-usb-c-hub-t3917848/post79289417#post79289417 This should supply enough power while using Dex via HDMI!
I'm recopying this from the Galaxy 9 thread referenced above in the hope someone here has tried this adaptor...
This thread is pretty old, but I'm finally looking at upgrading and have some questions about the Ugreen UCB C / USB 3.1 + HDMI Adaptor.
I'm looking at the USB C - 5 Port Adaptor here:
https://www.amazon.com/UGREEN-Adapte.../dp/B077FZQS95
In the notes it says that
USB C PD fast charging is only for laptops but not for phones. Phones only support normal charging.
Do NOT recommend you charge phone through USB 3.0 port as USB port only can only offer max 1.5A current and will charge your phone slowly
So I'm trying to figure out, is this like a powered USB hub that needs a PD brick to power the hub and then the hub powers the tabled (with 1.5A max), and separately powers the HDMI adaptor, UCB 3.1 devices etc., or is this a power-pass through that powers the tablet (slow) and then the tablet powers the USB devices?
In other words, is there an advantage to buying a $20-30 PD wall brick to power this hub, which the tablet doesn't support, or am I as good as I'm going to get with the original Samsung Lightning charger that came with the tablet?
Thanks,
Joe
I bought one of the U-Green hubs rated for 100W PD:
https://www.amazon.com/gp/product/B07RW343WG/
This one has two USB 3.0 ports, a USB C charger-in port, HDMI, and two card readers, one full size SD, one micro-sd.
Because all of the documentation specifies it uses power delivery type chargers, I was worried it would have problems with a Samsung lightning charger. No problems. With the original lightning charger, the tablet recharges to and holds at 100% even when loaded by hdmi, an external hard drive, a USB thumb drive, and a micro sd card. The simpler / cheaper hub I bought when I got the tablet discharges when hdmi + the same charger is plugged in.
The reviews complained it gets hot enough to burn your finger when touched, but I haven't noticed this at all. This could be a function of the total power delivered to the hub I believe the lightning charger is only 15W. The hub is rated at 100W with PD cgarger. So only a fraction of the power is transmitted through the hub when charging with Samsung lightning charger. It seems most of the 100W is used to charge a PD laptop or Apple device, not the peripherals.
The one change I'd make to it, is that I'd like to have a spring loaded recessed slot for the micro sd card reader. In this hub, it is pushed in / pulled out of the slot leaving ~ 1/4 inch sticking out from the body of the reader when the micro sd card is loaded. If you leave the card in all the time (to use as an external hard drive) there will be a danger of the card snapping. A minor quibble.
I'm happy that it allows the tablet to maintain 100% charge while running hdmi.

I have been trying a couple of multiport adapters (USB-C, USB-A, HDMI) but while USB-A and HDMI seem to work fine, the charging port seems to do nothing. The tablet does not indicate it is being charged, and when connected to a PC there is no data connection.
There is a suspicious remark in the documentation:
Operation
• Connect the plug to a USB-CTM port on your computer.
...
At the time this manual was written, Android smartphones were not supported.

So is it possible that this adapter is not supported by our Tab S4? I would be surprised since I read here that other adapters do work.
For completeness, it is a Renkforce USB C naar HDMI + USB 3.0 Multiport-adapter.

Your description is confusing to me, and I had to translate the product description of your adaptor from Dutch to English, but...
Plug the USB C male connector from the adaptor into your tablet. Your adaptor has three ports:
1) USB 3.0 female - connect to a USB device such as a mouse, keyboard, thumb drive, etc. I'm not sure if you can connect this port to a PC or not.
2) HDMI female - hook to a display
3) USB C female - power input port only. Does not carry data. Does not connect to a PC. Plug your power supply into this port using the same cable that you charge your tablet with.. The charging icon should activate. Your tablet should stay charged while using the other ports, or at least discharge more slowly.
It sounds like you are trying to plug the charging port into a PC. Doesn't work as far as I know.
Thanks for the reply. This is what I do:
1. Plug the USB-C cable from the adapter into the tablet C port.
2. Plug HDMI cable (connected to a monitor) into the adapter HDMI port. This is detected, Samsung Dex starts, and the monitor displays the Dex desktop.
3. Plug keyboard/mouse into the USB-A port of the adapter. This is picked up by the tablet and I can use the keyboard/mouse.
Alternatively, when I plug a USB stick into the USB-A port of the adapter, the tablet shows a new USB storage device.
So far, so good.
4. I connect the Samsung power supply to the USB-C port of the adapter. Nothing happens. The tablet does not start charging (or discharging less). I tried different power supplies and cables, makes no difference.
When I connect the power supply with the same cable to the tablet it charges normally. When I connect the tablet using this cable to a PC hub the tablet also start charging, albeit slowy.
So as far as I can see I did nothing wrong. What suprises me most is that almost everything works fine, except charging.
I've ordered a new adapter (different brand) to see if this makes a difference.
I think it should work... I have a couple adaptors similar to yours and they all work. Particularly Insignia NS-PU378CHM I referenced above.
I do think that adaptors that say they support power delivery (PD) work better than cheaper generic adaptors. Even though the Tab S4 doesn't support
PD itself. I strongly recommend the Ugreen adaptor above.
Good luck,
Joe
I would have bought the Ugreen immedeately if they were easily available in this part of the world. Buying from Amazon is expensive and delivery is slow.
I got myself another multiport hub, brand A-Konic, and this time all three ports seem to work correctly. USB-C charging. USB-A OTG and HDMI. However, Samsung Dex on the monitor is only 1280x720 (on the S4 it is 2560x1600; the monitor is 1920x1080). Not sure if this is related to the hub.
I'm glad you found something that works. I don't know about screen resolutions. There are other threads that discuss HDMI resolution. I think the HDMI cable can make a big difference.
Take care,
Joe

Initially I got a distorted image on the screen but replacing the high quality cable by an even higher quality cable fixed that.
I'll check out the resolution info.
Samsung Galaxy Tab S4 working 100w adaptor ?
Hello I have the following question to all owners of samsung galaxy tab s4. I have a desire to buy the following docking stantion for my tablet. I have a question if it will work correctly.
USB C Hub, USB C Docking Station, QGeeM 12 in 1 Triple Display Type C Hub to Dual 4K HDMI & DP,USB C to USB Adapter,100W PD, Gigabit Ethernet, USB C Card Reader,USB Docking Station
Samsung Galaxy Tab S4 does it support thunderbolt ?
Will work seamlessly with a 100w adapter?
It will work but it won't use all its capacity. The tablet only can charge at 18w.
I am having good luck with the AUKEY 5-in-1 USB-C Hub, here is the AMZN link:
https://www.amazon.com/gp/product/B089M7WSHM/
It will give screen mirroring to TV. I have used it on both a 720p and a UHD (2160x3840) TV.
It can charge through the hub and use HDMI out and ethernet on the S4. I just wish it wouldn't try to make me setup DEX everytime I plug it in.
was looking into upgrading to S20 but wondering if issue with S8 and S9/note9 has been fix thx for Samsung finally getting PD certification
So back in the day you could get USB C hub and hookup note9/S9 with pass-through charging, but charging speed wasn't enough to keep up with battery drain
playing a game or HDMI out or using GPS split screen with other app while hookup to hub will slowly drain your device even while charging ... eventually it will die.
or say using DEX
question is for people who already bought device S20 tested a USB hub with PD delivery see if there no difference in charging speed while phone is using say SSD or Harddrive or USB camera
and are charge levels while doing this able to keep up with drain speed / actually gaining % in battery rather loosing.
or does the OTG function is what limit all this from charging at respectable level
I did this with the s20u with the charger they provided it took 2 hours to charge no drain issue
If it's taking 2 hours it's probably charging at 5V/0.5A (2.5W) USB charging. So long as you leave it alone and don't use your phone it will charge .... Not doing PD charging (15W) that's a disappointing guess OTG disables anytype of fast charging.
If they would only enable 5V/2.4A normal USB charging I'll be happy under OTG
