Running cost
Among the thriftier 45–50 pint models
It uses 45 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 $91 saved in the United States.

Who it suits
On the ENERGY STAR table, the UDZ1-150P suits every space, wet ones over 2,000 sq ft included. It’s one of the cheaper models of its size to run.

Wi-Fi app
No app to watch it from upstairs
The EPA doesn’t list the UDZ1-150P 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 UDZ1-150P 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
- Its 475 kWh a year is 45 kWh less than the median for its size.
- Its refrigerant is R-32, flagged as lower GWP.Global warming potential 675.
- Tied for 8th of 156 certified 45–50 pint portables for low energy use.
- Its efficiency, 2.02 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.
- Yoau’s next size down is the UDZ1-120P, rated 35 pints.That one uses 135 kWh a year less.
- Sold since September 2025. Among 45–50 pint models, 45 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 Shinco models with the EPA.
- The nearest size from another brand is the Moiswell Aegis HP150, rated 50 pints and 530 kWh a year.In the United States, this one costs $10 a year less to run.

in the United States
A day of nonstop drying means 50 pints of water, about 6.3 gallons, for some 11.7 kWh. At the average home electricity price in the United States, the UDZ1-150P costs $2.14 to run that day.
The EPA’s yearly estimate, 475 kWh, adds up to about 41 days like that. Each extra day at full output costs another $2.14.
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 UDZ1-150P drains, since our sources don’t say.
