Has anyone successfully used a 12v usb charger other than the BN ripoff? I have a gmax 2.1a and aluratek 2a and neither one will charge the bn tablet. I get the "not charging" message on the tablet.. so I supposed its getting some juice, but not enough to sustain it. I soldered d+/d- together on both adapters and now both will show ac charging in the nexus - so I know each is getting close to 1amp. Ironically, the tablet will show ac charging if I use the nexus power ac power cube which is rated at 5v / 1amp output. So you would think the 12v usb adapters which are rated the same would work as well.

did you read about the 'special' connector that is deeper than the normal ones ? please use the search function for more info.
sure did.. all of this was with the [email protected] cable..

There's also the part of the equation where the USB adapter must supply a lot more than the 500mA of current that most adapters and computer USB ports are limited to. Mine will say "charging" as long as the adapter puts out around 1A (1000mA) or more and I use the NT's supplied cable. <-- But it still won't charge as quickly as it does when I use a 2A charger such as the one it came with. The factory charger is around 2A and expecting the NT to charge with anything less may not result how you'd like. Just because your phone likes a charger doesn't mean your NT will.
There is more to it than just shorting the D+ and D- pins. If the charger was designed for iPad, then you will also need to remove 4 resistors. Check out the two links in my post relating this issue at http://forum.xda-developers.com/showthread.php?t=1614091
I modded a car charger by just shorting the two pins. My HTC EVO 4G phone showed AC charging but my NT showed USB charging. I opened it up again and removed the resistors network and NT showed AC charging right away. Good luck.
bigdogz - good advice - made an attempt at it but my eyesight and hand steadiness aint what it used to be However, I did find one that works - Scosche reviveII - GUSBC3. Its a 2.1a port for the galaxy tab and a 1amp port for apple. It charges both the galaxy tab 10.1 and the nook tablet on the 2.1a port. It also will charge in ac mode a galaxy nexus from the tab port. The 1a port does not have the d pins shorted, but will charge an iphone.
Hello All,
I thought I should post all the extra stuff that I had to buy for my S8 here so others can look for it easily. The following items have been tested by me but do not hold me for anything that may or may not work for you.
I bought these screen protectors as I found them to be of good quality, durable and can fit into most S8 cases. I had one on my S8 when I dropped it on concrete! Luckily only the screen protector got shattered and not my new S8. So I ended up buying a few more as they are crystal clear, no issues with touch sensitivity and fit snugly in most cases. The link for tempered screen protector is this
https://www.aliexpress.com/item/3D-...32818410451.html?spm=a2g0s.9042311.0.0.SfZNbo
I also bought slim cases for s8 and the link to that is https://www.aliexpress.com/item/Msv...32804190382.html?spm=a2g0s.9042311.0.0.SfZNbo
Cables: the stock cable that came with S8 is only USB 2.0 certified.
I also had to buy usb type c to type c cable which is USB 3.1 Gen 2 certified as I wanted data transfer speeds of 10 Gbps and to use USB Power Delivery charging that is enabled in S8 as sometimes quick charge charger isn't readily available to me. So I purchased this cable which is tested and certified by USB-IF programme. This cable has 60 W charging capability along with 10 Gbps data transfer speeds and supports 4k display mode.
USB type c 3.1 Gen 2 cable link: https://www.amazon.co.uk/dp/B06XDB3...TF8&colid=1HNOKML5JAN5S&coliid=I29D160LWWJZPF
Following this I also had to buy a USB type A to type C USB 3.1 Gen 2 cable for data transfer speeds of 10 Gbps as stock cable took too long to transfer large files from my laptop to phone. This cable is USB-IF certified and again is USB 3.1 Gen 2 with 10 Gbps and 60 Watt of power delivery. This cable is also USB-IF certified.
USB type A to type C 3.1 Gen 2 cable link: https://www.amazon.co.uk/dp/B07213D...TF8&colid=1HNOKML5JAN5S&coliid=I1F1MQL9SCB29T
finally I had to buy a charger that could support USB Power Delivery as well as Quick Charge charging. So I bought this 48 Watt (USB PD 30 Watt and Quick Charge 18 Watt) charger which can charge my S8 at the same speed as the stock charger. I bought this charger because I think as we move more into the future, the USB Power Delivery will be the main port used (as google is pushing for it) and quick charge will be side.
I use the above charger with samsung fast wireless charger and it fast charges the phone. This is the wireless charger that I use https://www.amazon.co.uk/gp/product/B01BSOPVDM?psc=1&tag=ho01f-21 which isn't the latest and greatest due to its microusb connector limiting the wireless charger to 9 Watt charging capability. I understand that the new samsung wireless charger ( https://www.amazon.co.uk/Samsung-Wi...6756&sr=1-7&keywords=samsung+wireless+charger ) has USB type C socket however samsung charger only outputs 9 Watt max on the new charger so a bit pointless unless you are in for the looks. The point I am making here is that the Tronsmart charger will work with both samsung chargers and others and will provide quickcharge 3.0 capability.
You can buy non-samsung wireless chargers that are capable of charging at 15W for S8 and the Tronsmart charger will work with them as it can pump up to 18 Watt on quickcharge and 30 Watt on USB PD.
Just a note: S8 charges at max of 15 Watts on stock adaptive fast charger, USB PD and Quick Charge 3.0 and I guess Samsung didn't want to repeat Note 7 scenario so they have put this limit on S8 however you can charge other gadgets at a much faster rate especially on USB PD which can support up to 100 Watt of charging.
Hopefully anyone looking for accessories could use this information rather than spending money and time in testing different items as I had to.
Best,
V
Question about device. Does it need 18+W charger like Nintendo Switch? It's just both of them are the only mobile devices I have that doesn't (NS) or almost doesn't (SD) charge when on 5V charger.
When I correct Duo to 5V charger is its so slowly charging than when used is actually discharging...
it could be your charger or your cable. I have a 5V charger and it goes up to roughly 2amps while charging. I have a USB ammeter, tested it this morning because i thought I was having charger issues (a reboot fixed my issue)
This is the 100W Baseus deskop charger and I have two issues with it:
1. When two USB C ports are used, the power division is C1=65W and C2=30W. So C1 should still be more than capable enough to handle SFC 2.0 45W charging. But as you can see in the video, SFC 2.0 is not working when two USB C ports are used.
2. When I charge at SFC 2.0 and SFC 1.0 with the same charger, they both cap at 33W. I thought SFC 1.0 is just 25W? When I use the official 25W Samsung SFC 1.0 charger, it just caps off at 24W as expected.
Baseus support sucks big time so I'm having a problem reporting this to them.

Baseus GaN5 Pro 65 watt can charge at 50watt peak.
after 60 percent,watt same as samsung 25 watt charger.
But your measurement is input power to the charger and not output power to the phone. There's a bit of a difference because of power adapter efficiency. I don't know what is the difference between the Gan5 Pro 65W and this 100W adapter really.
BUMP! Anyone please?
This is normal for such a charger. I have a PZOZ version - 65W GaN 2xUSB C + 1xUSB A. SFC 2.0 works only with 1 device plugged in, if you plug another (it might be a 5W one) - this breaks the SFC. I can assume that this is coming from the controller and the device is actually not capable to support such scenario, even though the power is declared as 100W.
Hmmm, that's interesting. I thought the issue was isolated to BaseUS. Their support is really non-existent. They reply but it's like you're talking to a stupid person that does not understand the issue.
Aside from this issue, do you have any other issues when using both ports? As for me, when I charge my phone while my laptop is plugged in, it sometimes drops the wattage on the laptop device to just 19w. If the laptop is plugged in by itself, it goes up to 59w. Not sure what's going on here.
Are there any usb c car chargers that support sfc 2.0?

But I bought the 65W charger and BaseUS said that it can only do PPS 18W.
S23 Ultra requires 10v 4.5 amp to achieve 45 w charging . Charger and Cable both should be capable of 5 amp current capacity and Charger should support PD 3.0 with PPS at 5 amp that is the basic requirement, Cable should have a e-marker chip to identify it as having 5 amp capacity to the charger. usually such cables have 5 amp written on the USB C port and are visibly thicker than the normal 3 amp cables .

Do you have any reference for that 10V 4.5A information? Some say it's 9V 5A but I never saw any official claims from Samsung regarding that too. I have no issues with cables. I'm using 100W BaseUS cables with e-marker chips on them. They don't have the 5A writing on them but they are obviously thicker than the included Samsung cable (which is only for 25W charging). Here are the specs of the 100W BaseUS desktop charger that I have:
As you can see, it does support PD3.0. Although PPS is not written there, it does support it as well as confirmed by BaseUS support and the video that I showed. I don't see 10V anywhere though so I'm not sure how it works with PPS or something. Does PPS adjust the voltage with fine adjustments or something? Also, that doesn't explain the issue I'm having where SFC 2.0 won't work when two USB ports are used. It only works when the phone is charged alone and this defeats the purpose of buying a multi-port charger in the first place.
Go to settings, about phone , and then status information the last entry there is Rated 10 V 4.5 Amp . Yes pps adjusts voltage with fine adjustment of 20mv . It can provide between 3.3 V to 21 V at upto 5 Amp . Your problem seems to be related to the charger itself which is unable to deliver the required power when two usb ports are used . BTW you can use an app called accubattery which should give you the exact charging data for your phone.

Ok, I see that now. Well, @Stenlius replied to this thread and says that this is normal. Any comments on that?
What's more weird though is that when it's charging at sfc 2.0, the cable only shows 33w. When I plug in another device in the charger, it renegotiates to sfc 1.0 but still at 33w!
When I use the official 25w samsung charger with the same cable, it goes down to 24w as expected.
SFC 2.0 - So far I have only seen with the Samsung official chargers. I've spent so much money on Belkin, Baseus, UGreen, Anker accessories and never been able to get peak speeds.

Never had the tools to measure the wattage output.
I just plug and wait for SFC 2.0 to show up, and if it doesn't - I just get rid of it.
I've tried 120W Xiaomi chargers as well.
Max anything other than samsung genuine chargers can go up to is "Fast Charging" or super charging 1.0.

Well theh that's not the same case as mine. If you read my OP and watched the video, you'll see that I can do sfc 2.0 with this baseus charger but only maxes at 33 watts. I thought you had the same issue as mine.

Ok, that makes sense. I'll try charging at 15% and see if it makes it to 48W.
Also, have you tried charging yout s23 ultra with more than one usb port plugged in your charger? That does not work as you see in my video.

No there is none. I posted on reddit before buying this and one guy posted the same issue. Can you test with yours?
