MIFI-Hotspots that run off 12v?

[Calaverasgrande]

Looking up MIFI/Hotspot routers. The kind you can mount in your vehicle, not the kind you carry around in a briefcase.
Not sure if Amazon has accurate info because all of them either say 120v or 100-240V for powering.
That sucks!
When my electrical system is finished it should have no problem handing another 250MA of AC power. But I'd rather have more things directly 12V to avoid conversion loss. Since no inverter is 100% efficient, it will always be preferable to pull directly from battery.

Is anyone aware of a 12V powered Hotspot?

Most of them can be charged (or powered) by USB...meaning that all they really need is 5 volts. You can easily find USB chargers that are powered by 12 volts or 120 volts.
