I have multiple Pixel phones and can connect up to 8 devices. Generally, that works just fine for a single laptop and I can stream music on a second device. I struggle a bit with video running on Skype, Zoom, etc. 

My parking spot has wifi and I'd like to have access to my "home" network on the days I go into the office... 3D printers, cameras, temp sensors, NAS, desktop, etc.

I prefer to manage my own hardware, I do not want to use Speedify. I already have a VPN service that I use.

I would like to use channel bonding and get the boost in bandwidth. 

Which appliance would have the features I'm looking for?

PS I have looked, I have searched. Speedify is flooding the interwebs with their marketing hype and their fanboi's. No thanks.
