Diy battery box with 20amp solar mppt charge controller and 100Ah lifpo battery. 3x 12v sockets, 2x 5v USB sockets and 5 switches.
2x 200W solar panels keep the battery topped off
Box runs built in lights and fan and in addition my heating blanket and electric fridge and charges phones.
Haven't had a need for a 110v inverter, yet.
Battery is 100Ah Vestwoods LifePo with BT BMS
Solar MPPT Charge Controller is 20Amp HQST with BT monitor.
Whole set up cost about $450, much cheaper then commercial power stations with 1280Wh.

Good choice on the box, IP67 rated, I use them for their dust proof property. They’re so tight that the tops will flex with elevation/pressure change. Please report back on how it works for you.

Thanks! So far so good. I took it for a couple of nights in my camper in the snow, night temps dropped down to 24F. Battery/Solar/heating blanket worked just fine.

12V from Amazon: https://a.co/d/gJlnGgs, pulls about 2.5 - 3A when it's active. turns automatically on and off. I put it on the mattress, under the sleeping bag and it kept things comfortable. At 24F, it consumed about 15Ah/night.
