Our read
Who it suits
On the ENERGY STAR table, the ADSE50X**# suits every space, wet ones over 2,000 sq ft included. Its running cost is close to the median, so drainage, noise, and price matter more.
Capacity suggested for each case, read Oct 5, 2026. ENERGY STAR adds that it’s better to oversize than undersize.
Running cost
Its power bill is close to the norm
A portable lasts 11 years on average, by the DOE’s count. In that time, this model costs $2 less to run in the United States than the median 45–50 pint model. The thriftiest 45–50 pint model, the Aeocky LEO PRO-RCS50(Y)-N4-3(B)-25, would save $163 over those years.
The EPA doesn’t list the ADSE50X**# as connected. Of the 156 certified 45–50 pint models, 14 are. In a crawl space you rarely open, a connected one saves the trip.
Ask for the pump lift and the lowest working temperature
Our sources don’t say whether the ADSE50X**# has a pump, or how cold it can run. With no drain lower than the unit, the pump lift must reach your sink. Under 65°F, ENERGY STAR says the coils can frost.
At 519 kWh a year, it sits 1 kWh below the middle of its class.
Its refrigerant is R-32, flagged as lower GWP.Global warming potential 675.
Of the 156 certified 45–50 pint portables, 75 use less energy, and 1 uses exactly as much.
At 2.01 liters per kWh, it clears the federal minimum for its class by 26%.The DOE sets 1.60 L/kWh for portables rated over 25 and up to 50 pints a day. Every unit made since June 13, 2019, must meet it.
The largest portable certified under the GE name. Next down is the ADSE35W**#, at 35 pints.That one uses 164 kWh a year less.
On the market since November 2025, newer than 58% of the 45–50 pint models on the list.
Not on the EPA’s Most Efficient list, which names 8 of the 45–50 pint models.
Another brand near this size: the Honeywell TPFIT50AWK, at 50 pints and 516 kWh a year.In the United States, this one costs $1 a year more to run.

in the United States
A day of nonstop drying means 49.64 pints of water, about 6.2 gallons, for some 11.7 kWh. At the average home electricity price in the United States, the ADSE50X**# costs $2.14 to run that day.
The EPA’s yearly estimate, 519 kWh, adds up to about 44 days like that. Each extra day at full output costs another $2.14.
Those 49.64 pints come from a DOE test at 65°F and 60% humidity. Cooler air at that humidity gives up less water, so expect fewer pints in a cold basement.
Every day at full output leaves 6.2 gallons to get rid of. Check how the ADSE50X**# drains, since our sources don’t say.
