How efficient are NP portable ACs?

Of the 2 NP portable ACs, none files a higher CEER than the class median: 2 match it.

NP portable ACs against the median CEER (Btu/Wh) of their class. DOE data as of 2026-11-03.
Class	NP models	Above median	Class median	Best NP
Single hose portable ACs (1,044)	2	0	CEER 7.3	NPN-E508CE CEER 7.3

A higher CEER means more cooling per watt.

Who makes NP portable ACs?

DOE's database has no manufacturer field, so the evidence is whose model number each unit is filed under and which other brands file the same unit.

None of the 2 NP basic models is filed by another brand as of 2026-11-03, and none uses another company's model number. DOE's records tie them to NP alone.

How much does a NP portable AC cost to run?

While cooling, NP portable ACs draw about 1,096 to 1,096 W (certified SACC divided by CEER). That's 20¢ to 20¢ an hour, or $47.76 to $47.76 for 30 days at 8 hours a day.

At 18.16¢ per kWh, the US average residential price for August 2026 (EIA Electric Power Monthly, table 5.6.A). Worked out from the certified figures.

How does NP NPN-E508CE compare with other brands?

Picked by rule from models with a matched listing, DOE data as of 2026-11-03.

Within 1,000 BTU/h of its size, highest CEER: Hisense HAP0825TWD, 8,000 BTU/h SACC. Up to 350 sq ft, dual hose, CEER 13.5: about 46% less power for the same cooling.
Nearest size in its class with a higher CEER: BLACK+DECKER BPACT08NM, 8,000 BTU/h SACC. Up to 350 sq ft, single hose, CEER 12: about 39% less power for the same cooling.
Nearest bigger unit: icyberboom RHKT14030, 9,200 BTU/h SACC. Up to 400 sq ft, single hose, heats, CEER 7.6.

Questions about NP

Is NP a good portable AC brand?: How its 2 portable ACs compare on efficiency with their DOE class is above. Both are filed under NP alone. We don't test reliability, noise or build quality, so we can't rank brands on those. How we compare models.
How big a room will a NP portable AC cool?: Its models certify 8,000 BTU/h SACC, which ENERGY STAR's sizing chart puts at 350 sq ft. Every one was tested single hose. SACC and the BTU figure on the box.
Which NP portable AC is the most efficient for its size?: NP NPN-E508CE and NP NPN-E508CH tie at CEER 7.3: higher than 392 of the 1,044 single hose portable ACs certified to DOE.
