TCL T50DC9SPB dehumidifier: specs and cost to run

Our read

Who it suits

On the ENERGY STAR table, the T50DC9SPB 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.

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 $20 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 $185 over those years.

The EPA doesn’t list the T50DC9SPB 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 before you buy

Ask for the pump lift and the lowest working temperature

Our sources don’t say whether the T50DC9SPB 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.

From the data

Where it stands

At 530 kWh a year, it sits 10 kWh above the middle of its class.
Its refrigerant is R-32, flagged as lower GWP.Global warming potential 675.
Tied for 136th 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.
TCL’s next size down is the H32D44W, rated 32 pints.That one uses 187 kWh a year less.
Sold since May 2026. Among 45–50 pint models, 138 of 156 came out earlier.Certified in May 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.
The nearest size from another brand is the Yoau UDZ1-150P, rated 50 pints and 475 kWh a year.In the United States, this one costs $10 a year more to run.

in the United States

Run for a whole day at its rating, the T50DC9SPB removes 50 pints, about 6.3 gallons, on roughly 11.8 kWh. In the United States, that’s $2.16.

Divide the EPA’s 530 kWh a year by one full day’s use, and you get roughly 45 days. Past that, each day at full output adds $2.16 to the bill.

The DOE test behind those 50 pints runs at 65°F and 60% humidity. At the same humidity, a cooler basement gets less water out of the T50DC9SPB.

Without a hose or a pump, someone has to carry out 6.3 gallons a day. Our sources don’t say whether the T50DC9SPB has a bucket, or how much it holds.
