The math

Worked with the typical figure, as the calculator does it.

  1. Output1,200 W running, so the station's continuous output must be at least 1,200 W.
  2. SurgeNo start surge: the running figure covers it.
  3. Average draw1,200 W: the running watts count for every hour it is on.
  4. A typical day1,200 W × 1 h = 1,200 Wh a day.
  5. Typical 1 h a day1,200 W × 1 h = 1,200 Wh usable, ÷ 0.85 = 1,412 Wh of rated capacity.
  6. 8 hours of running1,200 W × 8 h = 9,600 Wh usable, ÷ 0.85 = 11,294 Wh of rated capacity.
  7. 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.

Questions

How many watts does a dishwasher (built-in) use?
About 1,200 W while running, from 792 W to 2,400 W across the models in our sources. Watts vary by model and age. Check the label on your own appliance and enter it for an exact answer.
Can a portable power station run a dishwasher (built-in)?
Yes. 43 of the 54 power stations in the Enough Watts data set can power it on its own. It takes at least 1,200 W of continuous output.
How long will a power station run a dishwasher (built-in)?
It depends on the battery. At 85% efficiency the smallest station that powers it, the BLUETTI Elite 100 V2 (1,024 Wh), gives about 44 min. The largest, the EcoFlow DELTA Pro Ultra X (12,288 Wh), gives about 8.7 h.
Does a dishwasher (built-in) need extra watts to start?
No start surge is published for this type, so the site checks it at its 1,200 W running figure. Watts vary by model and age. Check the label on your own appliance and enter it for an exact answer.

We read published figures and do the math; we do not measure appliances. The methodology states every formula on this page. Capacities are rated watt hours: 1,000 Wh rated gives 850 Wh usable at the default.
