Spring and thunderstorms before you know it. But yes, Damn this mess.

Nice! Is that 1800w per switched circuit or t800w per plug? Same basic problem though, no T-Mobile up here.

Hey guys, the Switchbox is 1800W total, from one plug or split across the 2x plugs.

Most of our pilots use the Engine Heater on outlet1 - 500-750Watts
And a cabin heater on Outlet2 for the avionics inside - 1000Watts

They use the free app to stagger the devices. So night before for Engine HEater and few hours before for Cabin Heater. Here is a sample video showing you how the app works and device gets setup

Also, the T-Mobile problem is solved with an AT&T card installed inside, instead. A lot of the rural pilots prefer AT&T because it has better service.

So far we are doing really well, about 2000x pilots setup with Switchbox in USA and no returns this season from any issues at all

PS We have a bunch of guys using the Switchbox for planes on Skiis, and working great in the snow. They put it in a pelican case and leave it outside
