Running cost
Among the thriftier 45–50 pint models
It uses 82 kWh a year less than the median 45–50 pint model. Over 11 years, the DOE’s average life for a portable, that’s about $165 saved in the United States.

Who it suits
On the ENERGY STAR table, the LEO PRO-RCS50(Y)-N4-3(B)-25 suits a wet space under 2,000 sq ft, or a very damp one over. It’s one of the cheaper models of its size to run.

The EPA doesn’t list the LEO PRO-RCS50(Y)-N4-3(B)-25 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 LEO PRO-RCS50(Y)-N4-3(B)-25 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.
Plan the drainFrom the data
Where it stands
- At 438 kWh a year, it sits 82 kWh below the middle of its class.
- Its refrigerant is R-32, flagged as lower GWP.Global warming potential 675.
- Ranks 1st of 156 certified 45–50 pint portables for low energy use.The median of its size is 520 kWh a year.
- Its efficiency, 2.21 liters per kWh, is 38% above the federal minimum for its capacity class.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 Aeocky name. Next down is the RHEA PRO-RCS50(Y)-N4-3-25, at 44 pints.That one uses 6 kWh a year less.
- On the market since February 2026, newer than 76% of the 45–50 pint models on the list.
- On the EPA’s Most Efficient list, like 7 other 45–50 pint models.
- The company that files it also files models under 7 other brands with the EPA, among them Deciuu, Easykey, and Greenlite.
- The nearest size from another brand is the Vellgoo TAURUS PRO-RCS50(Y)-N4-3-25, rated 45 pints and 444 kWh a year.In the United States, this one costs $1 a year less to run.

in the United States
In 24 hours at full output, the LEO PRO-RCS50(Y)-N4-3(B)-25 pulls about 5.6 gallons of water from the air and uses about 9.6 kWh. That day costs $1.76 in the United States.
About 46 such days make up the EPA’s yearly estimate of 438 kWh. If yours runs at full output more often, every extra day adds $1.76.
Its rating comes from a DOE test at 65°F and 60% humidity. In cooler air at that humidity, the LEO PRO-RCS50(Y)-N4-3(B)-25 pulls out less than 44.94 pints a day.
Those 5.6 gallons need a way out: a hose to a drain, a pump, or a bucket you empty. Our sources don’t say which ones the LEO PRO-RCS50(Y)-N4-3(B)-25 has.
