What size power station for a dishwasher (built-in)?
It needs a station with at least 1,200 W of continuous output. At the default 85% efficiency it takes about 1,412 Wh of rated capacity for its typical 1 h a day, and 11,294 Wh for 8 hours of running. 43 of the 54 power stations in the Enough Watts data set can power it. The smallest one that keeps it going for 8 hours of running is the EcoFlow DELTA Pro Ultra X (12,288 Wh).

The math
Worked with the typical figure, as the calculator does it.
- Output1,200 W running, so the station's continuous output must be at least 1,200 W.
- SurgeNo start surge: the running figure covers it.
- Average draw1,200 W: the running watts count for every hour it is on.
- A typical day1,200 W × 1 h = 1,200 Wh a day.
- Typical 1 h a day1,200 W × 1 h = 1,200 Wh usable, ÷ 0.85 = 1,412 Wh of rated capacity.
- 8 hours of running1,200 W × 8 h = 9,600 Wh usable, ÷ 0.85 = 11,294 Wh of rated capacity.
- On the EcoFlow DELTA Pro Ultra X12,288 Wh × 0.85 = 10,445 Wh usable, ÷ 1,200 W = 8.7 h.

What moves the number
A pump and a water heating element share the load, and the element runs for only part of the cycle. Current models list 792 W and up; 2,400 W, the top of the range, is a generator maker's chart figure. The math here counts the running watts for the whole hour of a cycle, the cautious case.
