Our read
Who it suits
At 50 pints a day, the Sailing P155A fits every space in the ENERGY STAR table, wet ones over 2,000 sq ft included. Its yearly energy use sits near the median, so weigh drainage, noise, and price.
Capacity suggested for each case, read Oct 5, 2026. ENERGY STAR adds that it’s better to oversize than undersize.
Running cost
A middle-of-the-pack power bill
Next to the median 45–50 pint model, this one costs $20 more to run in the United States over 11 years. That’s how long the DOE expects a portable to last. The thriftiest 45–50 pint model, the Aeocky LEO PRO-RCS50(Y)-N4-3(B)-25, would save $185 over those years.
Like 141 other 45–50 pint models out of 156, the Sailing P155A has no Wi-Fi app on the EPA list. In a basement you rarely visit, plan to check it in person.
Pump and cold are the two blanks for the Sailing P155A in our sources. A pump matters when water can’t run down to a floor drain. Cold matters because below 65°F, ENERGY STAR says frost can form on the coils.
Its 530 kWh a year is 10 kWh more than the median for its size.
Its refrigerant is R-32, flagged as lower GWP.Global warming potential 675.
Of the 156 certified 45–50 pint portables, 135 use less energy, and 20 use 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 Airecoler name. Next down is the Sailing P120A, at 38 pints.That one uses 156 kWh a year less.
On the market since May 2026, newer than 90% of the 45–50 pint models on the list.Certified in June 2026, one of the 97 models certified in the last six months.
Not on the EPA’s Most Efficient list, which names 8 of the 45–50 pint models.
Another brand near this size: the Yoau UDZ1-150P, at 50 pints and 475 kWh a year.In the United States, this one costs $10 a year more to run.

A day of nonstop drying means 50 pints of water, about 6.3 gallons, for some 11.8 kWh. At the average home electricity price in the United States, the Sailing P155A costs $2.16 to run that day.
The EPA’s yearly estimate, 530 kWh, adds up to about 45 days like that. Each extra day at full output costs another $2.16.
Those 50 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 6.3 gallons to get rid of. Check how the Sailing P155A drains, since our sources don’t say.
