8,000 BTU (SACC) single-hose portable air conditioner and inverter

Midea MAP08V1JWT

Excellent efficiency for its size: a CEER of 12.0 beats 99% of the certified 8,000 BTU portable air conditioners.

The Midea MAP08V1JWT delivers 8,000 BTU of real cooling (SACC), enough for about 250-350 sq ft, draws about 667 watts and costs about $90 a year to run at typical U.S. use and prices. A window unit that cools as much costs about $72 a year.

A good fit if…

  • You want low bills - its CEER beats 99% of the 710 certified 8,000 BTU portable models.
  • You want steadier, quieter running - its variable-speed compressor slows down instead of cycling.
  • You do not want to empty a bucket - it evaporates the water and sends it out through the hose in normal weather.

Think twice if…

  • You want the most efficient design - one-hose units pull warm air in through gaps; dual-hose units lead the efficiency ranks.
  • You also need heat - it cools only.

These model numbers are certified with the same capacity, efficiency, hose design, heating, drain type and compressor as the Midea MAP08V1JWT.They may be the same unit sold under several brands, or different products that test the same: the DOE data has no dimensions or noise figures, so check those with the maker. Ratings within about 2% in capacity and 0.3 in CEER are treated as the same; a model whose own rating differs a little shows it in brackets.

Questions7
What size room does the Midea MAP08V1JWT cool?
8,000 BTU of real cooling (SACC) suits about 250 to 350 sq ft with normal sun and two people (about 225-315 sq ft if very sunny), by the ENERGY STAR floor-area table. Size by SACC, not the larger BTU on the box.
How many watts does the Midea MAP08V1JWT use, and what does it cost to run?
About 667 watts at full power (8,000 BTU/h divided by its CEER of 12.0), roughly 5.8 amps if it runs on 115 V. At 750 hours a year and 18.0¢/kWh that is about $90, which is $58 less than the typical certified 8,000 BTU portable unit ($148). Its inverter compressor slows down once the room is cool, so real use is often lower. Its CEER beats 99% of the 710 certified models in its size class.
Is a one-hose portable air conditioner a problem?
It is the common design: 92% of the certified 8,000 BTU models have one hose, with a median of 7.3 CEER. The top-ranked Hisense HIAP0825TWD has two hoses and 13.5 CEER.
Do I have to empty the Midea MAP08V1JWT?
Usually not. It evaporates the water it removes and sends it out through the exhaust hose. In very humid weather the pan can still fill, and most units then stop and ask to be drained, so keep a drain hose or a bucket handy.
Can the Midea MAP08V1JWT also heat the room?
No, it only cools. 146 of the 710 certified 8,000 BTU portable models can also heat if you want one unit for the year.
Is the Midea MAP08V1JWT as efficient as a window air conditioner?
No. The 30 ENERGY STAR certified window units that cool about as much (within 15% of 8,000 BTU) have a median CEER of 15.0, against 12.0 here, and the best reach 17.0. At 750 hours a year a window unit with that median would cost about $72, $18 less than this one. ENERGY STAR window units are the more efficient part of the window market, so the gap to an average window unit is smaller. A portable unit makes sense when a window unit will not fit or is not allowed.
Which model numbers have the same ratings as the Midea MAP08V1JWT?
3 certified model numbers from 2 brands share these ratings: capacity, CEER, hose design, heating, drain type and compressor. They may be the same unit under different brands, or different products that test the same; the DOE data does not include dimensions or noise, so check those with the maker.

Power draw is capacity divided by CEER, which already includes standby power. Inverter units often run below full power, so real use can be lower. Electricity prices: U.S. EIA residential averages (12 months to July 2026). Days a year start from your state's cooling degree days (NOAA 1991-2020 normals).
