Apartment power outage: power station size

The setup

The loads, with the goal of one full day without a recharge
Appliance	How many	Running	Energy a day
Wi-Fi router and modem	1	28 W	28 W × 24 h = 672 Wh
Laptop (while charging)	1	65 W	65 W × 6 h = 390 Wh
Phone charging	2	20 W	20 W × 2 h × 2 = 80 Wh
LED bulb, 60 W equivalent (800 lumens)	3	8.5 W	8.5 W × 5 h × 3 = 128 Wh
Box fan (20 inch)	1	125 W	125 W × 8 h = 1,000 Wh

Running, everything on at once: 28 + 65 + 2 × 20 + 3 × 8.5 + 125 = 284 W
Starting watts needed: 284 W, no load starts above its running watts
Watt hours a day: 672 + 390 + 80 + 128 + 1,000 = 2,270 Wh
Goal: one full day without a recharge (24 h)

Enough: 17 of 54 stations

The 54 power stations in the data set, ranked smallest capacity first (the closest fit), then lower price, then lighter. Whether a link can earn us money never changes the order.

Cannot power it: 1 of 54 stations

Show the 1 stations and the number each one fails on

BLUETTI Elite 10 Mini Needs 284 W running at once; this station gives 200 W.

What to know

In an apartment the power station has to run indoors and come up the stairs. A fuel generator cannot run inside or on a balcony by a window: Ready.gov says to keep one outdoors and 20 feet from doors and windows. A battery station has no exhaust, so it can sit by the desk.

This list leaves the refrigerator out and keeps you working, lit and cool: the router, a laptop for 6 hours, two phones, three lights and a box fan for 8 hours. It uses 2,270 Wh a day and needs 284 W with everything on. The fan is the largest share, 44%, at 125 W; a smaller fan or a lower setting cuts it, and its label gives the watts to enter in the calculator.

17 of the 54 stations are enough for the day. Weight is the other number to read when you carry the station up: the closest fit, the BLUETTI Apex 300, weighs 83.8 lb (38 kg). The lightest station that is enough is the BLUETTI Elite 300 at 58 lb (26.3 kg).

Food in a closed refrigerator stays cold for about four hours without power, so a short outage may not need it on the list. The question below puts it on and shows what that does to the sizes.

Questions

What size power station do you need for an apartment power outage?

This setup uses 2,270 Wh a day. Lasting 24 hours takes 2,270 Wh usable, about 2,670 Wh of rated capacity at 85% efficiency. It also needs 284 W of continuous output.

Which is the smallest power station that is enough?

The BLUETTI Apex 300, at 2,765 Wh: 2,350 Wh usable gives 24.9 h of this routine. The ranking puts the smallest capacity first, then the lower price, then the lighter unit.

What if the refrigerator goes on the list?

With a modern full size refrigerator added, the setup uses 3,570 Wh a day and needs 559 W running and 1,284 W to start. 4 of the 54 power stations are enough for one full day without a recharge, against 17 for the setup above. The closest fit is the OUPES Guardian 6000 V2 (4,608 Wh).
