MIONJO V3 against the category
That's 48.1% below the dehumidifier category average of 378 kWh/yr, and ranks 73 of 546 certified dehumidifiers for annual running cost, 1 being cheapest. The category average comes from every dehumidifier ENERGY STAR currently certifies (546 models), not an outside benchmark, about $34/year below that average at the national rate. See the methodology page.
What sits beside it in the ranking
DOGHLY FDD20-5272V1R5-E ($37/yr, 198 kWh/yr) costs a little more to run than the MIONJO V3. AirCyan GF20C-20RW ($37/yr, 196 kWh/yr) costs a little less.
Within the MIONJO lineup
The MIONJO V3 is the only dehumidifier from MIONJO that ENERGY STAR currently certifies, so there's no same-brand model to weigh it against here, only the full dehumidifier category.
Lifespan
NAHB's Study of Life Expectancy of Home Components does not publish a figure for dehumidifiers, so no lifetime cost is shown here rather than a guessed one. The annual and monthly figures above stand on their own.
Shopping for a new one
The MIONJO V3 is already efficient for its category at $37/year. If you're shopping and comparing options, this is roughly what a well-chosen new dehumidifier costs to run.

Protecting what you have
At $37/year just to run, a dehumidifier is worth protecting against an unplanned repair bill on top of that.
Sourcing
At rank 73 of 546 for running cost, see the dehumidifier category page for the rest of the field, or the guide to how much your state matters. The 196 kWh/yr figure is ENERGY STAR's own certification, not a wattage estimate; exact dataset IDs are on the data sources page.
