How much does the Nepsam NS1309PAC12 cost to run?

About 20¢ an hour of cooling, or $47.31 for 30 days at 8 hours a day (less once the compressor cycles off).

8,250 BTU/h SACC divided by a CEER of 7.6 is about 1,086 W while cooling. Electricity at 18.16¢/kWh, the US residential average for August 2026 (EIA Electric Power Monthly, table 5.6.A). Each 1¢/kWh you pay above or below 18.16¢ moves the 8 hour figure by 9¢.

How does the Nepsam NS1309PAC12 rank in its DOE class?

In its DOE class (single hose portable ACs), 171 models have a matched Amazon listing. 56 of them have a higher CEER than its 7.6, which is 4% above their median of 7.3.

Questions

What is the Nepsam NS1309PAC12's real BTU?
It's certified to DOE at 8,250 BTU/h SACC (seasonally adjusted cooling capacity), the rating DOE requires for portable ACs. A box figure labeled ASHRAE is usually higher for the same unit because it comes from a different test: SACC vs ASHRAE.
Is it single hose or dual hose?
It was tested as a single hose unit, per the DOE record.
How big a room does it cool?
About 350 sq ft. ENERGY STAR's sizing chart calls for 8,000 BTU/h in rooms up to 350 sq ft. A sunny room, a kitchen or a high ceiling needs more.
How much does the Nepsam NS1309PAC12 cost to run for 8 hours?
About $1.58 for 8 hours of cooling: roughly 1,086 W at 18.16¢/kWh, the US residential average for August 2026 (EIA).
