Hi,
I have a Cosmos running wireless. after alot of the ryzen watchdog bsod problems I finally got i running without any problems (still on same ryzen) :-)
I use the "Anker PowerCore Speed 20000" for my setup. It supports Qualcomm Quick Charge 3.0 (24W) "Output 5-8V ⎓ 3A / 8-10V ⎓ 2.4A / 10-12V ⎓ 2A"
It seams to be working fine. it runs just over 3 hours before the need to recharge.
