What to know

A storm that brings down lines can leave a street dark for days. This list is lean on purpose: the refrigerator, the router for 12 hours a day, two phones and two lights. It uses 1,801 Wh a day, so three days take 5,403 Wh usable, about 6,356 Wh of rated capacity at 85% efficiency.

One station in the data holds that much, the closest fit being the EcoFlow DELTA Pro Ultra X (12,288 Wh). 43 more run the list but not for 72 hours; the longest of them, the EcoFlow DELTA Pro Ultra, lasts 2.9 days.

The refrigerator is 72% of the energy. Every hour it stays off saves about 54 Wh, and food in a closed refrigerator stays cold for about four hours without power, so short breaks cost little.

Recharging is how a mid size station covers three days. At 4 peak sun hours, counting 75% of the panel rating, about 610 W of panels put back one day of this list. The solar guide works through panel sizes, and every station page lists its car charging input. The question below shows how many stations reach two days on one charge.

Questions

What size power station do you need for a 3 day power outage?
This setup uses 1,801 Wh a day. Lasting 72 hours takes 5,403 Wh usable, about 6,356 Wh of rated capacity at 85% efficiency. It also needs 360 W of continuous output and a surge rating of 1,085 W for the start.
Which is the smallest power station that is enough?
The EcoFlow DELTA Pro Ultra X, at 12,288 Wh: 10,445 Wh usable gives 5.8 days of this routine. The ranking puts the smallest capacity first, then the lower price, then the lighter unit.
Which power stations last two days of this list?
4 of the 54 stations last 48 hours on one charge, against 1 for 72 hours. The smallest is the OUPES Guardian 6000 V2 (4,608 Wh), with about 2.2 days.
