Please also consider the GL-iNEt Puli (XE300): - 5V 2A USB C connector and a 5000mAh battery - SIM and [not tested by myself] eSIM support. - Tailscale and Nebula available as a plug-in. - Main network and guest network can be set. - OpenWRT if you want the GL-iNET firmware.
I am running a Netgear Nighthawk when I am on the road. But the Mubi7 looks interesting - I would not want to go back from 5G to a slower networks, sorry :)
