Our read
Who it suits
On the ENERGY STAR table, the MAD50P1AWS-A suits every space, wet ones over 2,000 sq ft included. Pelonis lists a model with the same EPA figures, so compare prices.
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 $10 more 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 $175 over those years.
The company that files it with the EPA lists the Pelonis PAD50P1ABLS with the same capacity, energy use, and efficiency. Compare their prices and warranties before you choose.
Wi-Fi app
No app to watch it from upstairs
The EPA doesn’t list the MAD50P1AWS-A 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 MAD50P1AWS-A 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 525 kWh a year, it sits 5 kWh above the middle of its class.
Its refrigerant is R-32, flagged as lower GWP.Global warming potential 675.
Tied for 103rd of 156 certified 45–50 pint portables for low energy use.
Its efficiency, 2.01 liters per kWh, is 26% 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.
Midea’s next size down is the MDUDP-40AEN8-BB0, rated 42 pints.That one uses 95 kWh a year less.
Sold since October 2025. Among 45–50 pint models, 62 of 156 came out earlier.
Not on the EPA’s Most Efficient list, which names 8 of the 45–50 pint models.
The company that files it also files the Pelonis models with the EPA.
The nearest size from another brand is the Amazon Basics B0GR2TN8YX, rated 50 pints and 525 kWh a year.Both cost the same to run in the United States.

in the United States
A day of nonstop drying means 49.74 pints of water, about 6.2 gallons, for some 11.7 kWh. At the average home electricity price in the United States, the MAD50P1AWS-A costs $2.14 to run that day.
The EPA’s yearly estimate, 525 kWh, adds up to about 45 days like that. Each extra day at full output costs another $2.14.
Those 49.74 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 MAD50P1AWS-A drains, since our sources don’t say.
