Several companies offer 3G/4G hotspots. Some or all have rechargeable batteries that let you run for awhile without having a power connection.
Prices are going to vary. Unlimited is more expensive, of course. Some offer more data traffic on 4G than on 3G. But that could be partly because they have better coverage on one over the other. Or maybe it's more expensive to run one than the other. Usually they'll tell you it's one level for 4G and another for 3G on the same plan. That's because you may end up in areas where 4G doesn't work well or at all. There's a lot of that going around.
I just bought one myself. I'm looking at hooking it up in my truck for mobile wifi (if I can ever get the damned thing to activate). It was a Virgin Mobile model. Since I'm just testing this right now, I'm going with a low data plan. It's pay-as-you-go, so I can drop it if it doesn't work out (most of the others require you sign up for a dedicated plan for a couple of years). But it's also on Sprint. If you don't know, Sprint coverage is great where they have it except it's spotty, A lot of spots are terrible and a lot of others just drop out. But it's wonderful if you aren't in those spots. And if you in metropolitan areas or near major highways.
