24 hour power outage: what size power station

The setup

The loads, with the goal of a full day at home without the grid
Appliance	How many	Running	Energy a day
Refrigerator (modern, full size)	1	275 W	1.3 kWh a day × 24/24 h = 1,300 Wh
Wi-Fi router and modem	1	28 W	28 W × 24 h = 672 Wh
Phone charging	2	20 W	20 W × 2 h × 2 = 80 Wh
LED bulb, 60 W equivalent (800 lumens)	4	8.5 W	8.5 W × 5 h × 4 = 170 Wh
TV, 55 inch LED (LCD)	1	82 W	82 W × 4 h = 328 Wh
Laptop (while charging)	1	65 W	65 W × 4 h = 260 Wh
Microwave oven (1,000 W cooking power)	1	1,530 W	1,530 W × 0.25 h = 383 Wh

Running, everything on at once: 275 + 28 + 2 × 20 + 4 × 8.5 + 82 + 65 + 1,530 = 2,054 W
Starting watts needed: 2,054 - 275 + 1,000 = 2,779 W
Watt hours a day: 1,300 + 672 + 80 + 170 + 328 + 260 + 383 = 3,193 Wh
Goal: a full day at home without the grid (24 h)

What to know

A full day at home without the grid asks for more than the essentials: the refrigerator, the internet, two phones, four lights, the TV for the evening, a laptop for 4 hours and a few minutes of microwave cooking. Together they use 3,193 Wh a day.

Two loads set the answer. The microwave draws 1,530 W, which lifts the list to 2,054 W with everything on at once, so 25 of the 54 stations fail the output check before the battery counts at all. The refrigerator takes 41% of the energy, and its compressor start raises the surge need to 2,779 W.

The microwave counts for 15 minutes a day here and uses 383 Wh, a small share of the energy. It decides which stations can power the list, not how long they last. The question below takes it off the list, for a home that heats food on a gas stove.

To stretch the battery, switch the screens off first: the TV and the laptop use 588 Wh of the day. The outage essentials setup drops them and the microwave, so a smaller station lasts the day there. Every station that is enough here also powers that list for longer, because it needs less power and less energy.

Questions

What size power station do you need for a 24 hour power outage?

This setup uses 3,193 Wh a day. Lasting 24 hours takes 3,193 Wh usable, about 3,756 Wh of rated capacity at 85% efficiency. It also needs 2,054 W of continuous output and a surge rating of 2,779 W for the start.

Which is the smallest power station that is enough?

The BLUETTI Elite 400, at 3,840 Wh: 3,264 Wh usable gives 24.5 h of this routine. The ranking puts the smallest capacity first, then the lower price, then the lighter unit.

What changes without the microwave?

The list needs 524 W running and 1,249 W to start, and 2,810 Wh a day. 11 of the 54 stations fail a power check, against 27 with the microwave, and 10 are enough for the full day. The smallest is the ALLPOWERS R4000 (3,456 Wh), with about 25.1 h.
