Power stations, radios, and the specs that matter.

Measure the load, then size the pack
The P3 P4400 Kill A Watt reads watts, volts, amps, and kilowatt-hours on a 115 V circuit. It is rated to 15 A, 125 V, and 1875 VA. It does not measure 240 V. Plug in the fridge or the charger, note the watts while it runs, then leave it for a full cycle and read kilowatt-hours. A power station's useful number is watt-hours, not the surge figure on the box. A steady 100 W load on a 1000 Wh pack is about 10 hours before inverter loss and cold weather. Measure the load. Then pick the pack.
The Midland GXT1050VP4 is sold as a GMRS pair. In the US, transmitting on GMRS needs an FCC license. One license covers you and your immediate family, and there is no exam. The listing says up to 36 miles. That is an open-terrain maximum. Reviews on the same page split, and some people report well under a mile. Each radio takes the included rechargeable pack or 4 AA cells. Program one channel, walk until the other radio drops out, and write that distance down.
Both brands sell portable power stations in overlapping watt-hour classes. Compare watt-hours, continuous inverter watts, and whether you can add a second battery. When those three numbers match, a 1000 Wh class pack from either brand does the same job. A cabin photo is not a runtime. Affiliate links for Jackery and BLUETTI are not up.
