I've seen some people having similar issues, but not quite the same (especially since I don't have a gaming rig).
Machine: Acer Swift 14 (Swift SF14-61T)
Brick: Anker Nano Charger, 100W MacBook Charger, Foldable Charger for iPhone Series, and All USB C Devices, 6ft USB-C Cable Included (https://a.co/d/a2Z3bra)
Also bought a separate 10-ft cord: Anker 544 Bio-Nylon USB-C to USB-C Cable 10FT, Eco-Friendly Fast Charging Cable, Supports 140W (https://a.co/d/8POjgxr)
What's REALLY crazy - my laptop has 2 USB-C ports that support charging (used both with the OEM laptop charger). However, when using the Anker Brick with the separate Anker cord, only one of the USB-C ports will actually charge. Even crazier? The 6-foot cable that came with the brick works perfectly fine in both ports! I had bought 2 of the 10-ft cords, and same thing with both, where they charge with one USB-C port and not the other.
I figured it was just something with the style 10-ft cord from Anker, so bought ANOTHER 10-ft cord from Anker: Anker USB C to USB C Cable, Type C Charging Cord Fast Charge(10FT,100W) (https://a.co/d/8yHY3fX)
And the same thing with this one! Is it something about the cords being 10-ft? I can't imagine how, but this is just so bizarre.
Any help would be appreciated (or links to working 10-ft 100W chargers haha)
