On my unsupported Ubuntu 23.04 and mainline 6.5 kernel hibernate works just fine, although I do lose the running applications occasionally. It's not exposed in the UI though - I have to manually run systemctl hibernate

I'm not sure where in the world you are, but to my North American ears I've never heard of Teknet. Could be a bad brand, or a bad model where it can (in theory) hit 100w but fails spectacularly when you try.
FWIW, both my ugreen, aukey, and Anker chargers of various wattage are working fine.
