Not sure if you've seen it already, but the Zendure Passport 2 Pro is a travel adapter (supports plugs with a ground pin as well), 61W PD, 2C and 3A ports that uses GaN. It is in the typical travel adapter form factor though so a bit bigger and heavier than your current setup.

Personally worth it for me for the full speed laptop charging. There are no-brand ones popping up on Amazon as well for a little cheaper.
