I’m using a GLinet GL-XE3000 for that and it’s great. Initial setup of the 5G eSIM on a physical SIM took a little searching but it’s been rock solid and having consistent access on the road and hotels has been great for family travel. It has a built-in battery, but I’ve never really tested the duration (I suspect it’s 3-6 hours) as I put it on its AC adapter in the hotel and the n a cigarette lighter adapter in the car, so the battery gets used 15-45 minutes at a time to bridge between those two places.
I like it enough that I might buy a second, more compact unit for when space is more a premium, but I’ve been really happy with this one.
I bought that specific model to provide connectivity for our robotics team’s pit computers. For this need, good antenna performance is key, since different venues differ wildly in WiFi and cell coverage and when we setup the evening before comps, I want the best chance of getting a solid connection and offering it to the pit LAN.
But now that I have it, the device is handy for family travel as well. Put an unlimited data eSIM in the device and everyone has “unlimited” data n the road and when we arrive at a hotel or AirBnB, one person signs it on to wifi and everyone is connected, including tailscale connections to home.
If I was doing personal and work travel only, I’d look for a smaller unit, but still with a decent battery.
