Ah.. OnePlus is a special kind of brand pulling an Apple move when it comes to charging. Only their chargers will do fast charging. Nothing else. I've got an anker charger that supports 60w PD and QC, other brands of phones and devices quick charge no problem, but not my two OnePlus devices - 5 & 9 PRO P.s over the years I have tested a handful of portable batteries and chargers from other vendors. Nothing seems to work.

Nothing seems to work. It should still normal slow charge though with pretty much anything. If I read the OP correctly it doesn't even do that. It should also fast charge with Oppo's chargers. And medium-fast charge with regular USB-PD on newer phones like my OP8. The separate charge tech is annoying but I have to say my 35W charging phone gets a lot less hot than my old Samsung S8 when slow charging. So I do think they have a point.

  To correct myself, it stays at the same battery level, so some current must be flowing. I have not tried for extended period of times (> 2hour). The thing is, on the one plus charger it goes to 100% in that time. I will keep it plugged for the night and see where it goes. So there is no way to fast charge it, even with some adapter? That's disappointing. Edit: I realize it was charging was faster (but not as fast as official adapter) with my older motherboard, so I guess there is still another issue here.

    But does the phone say "charging"? This is the indicator of slow charging (as opposed to fast charging, warp charging or whatever buzzwords they come up with). Regular charging is only 2.5W so it is technically possible for the phone to use as much as that while you keep the screen on and run a heavy app. Leading to what you describe, the battery never reaching 100%. It will of course also require hours to charge at that speed. Check your battery graph. If it stabilizes there may be a background app using a ton of power. But yeah fast charging a 5T is never going to work without its own charger. Only the latest OP models can do that and even then not as fast as they can with their own charger. If you want this get another brand next time. Although most brands are now moving away from standard USB-PD for everything and require USB-PD with PPS which allows fast and fine voltage adjustments. USB-PD has only a few set voltages and needs an interruption and slow negotiation for every change in voltage. PPS can do fine adjustment on the fly. The reason that fine adjustments are needed for ultra-high charging speeds is to remove the bulky and heat-generating high-power DC-DC converter from the phone itself and move it to the charger where heat and space are not so much of an issue. It's basically what oneplus has done for years but now in a standard way (and not compatible with OP's implementation) No laptop charger or port I know of supports this USB-PD-With-PPS right now. It'll still charge medium fast though. 18W or so (which is not actually a lot in most modern phones that have speeds of up to 100W sometimes)

      After the night, it went from 11% to 15%, ans it says "charging". So I guess I wasn't right when I say it didn't charge.

        Yeah check then if there an app keeping the phone awake. I bet that's it.

    Your OnePlus 5T have an USB 2.0 with USB-C port which by default should be charging with minimum of 2.5W. A full charge from zero to full would take 6 hours. This is likely what you are seeing now. Your old MB was likely charging at default USB-C port which "should" have a minimum of 7.5W charging, i.e 3x of what you are getting. My guess is that OnePlus is looking for USB-PD 1.0 but your newer Motherboard only support USB-PD 2.0 and 3.0. So it somehow dropped back to the minimum USB2.0 charging standard. Again you should look at BIOS settings to see if there are any relevant options.
