How much does the GUNJI GJ1309PAC14 cost to run?

About 23¢ an hour of cooling, or $55.42 for 30 days at 8 hours a day (less once the compressor cycles off).

10,300 BTU/h SACC divided by a CEER of 8.1 is about 1,272 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 10¢.

How does the GUNJI GJ1309PAC14 rank in its DOE class?

In its DOE class (single hose portable ACs), 171 models have a matched Amazon listing. 7 of them have a higher CEER than its 8.1, which is 11% above their median of 7.3. On cost, the same 10,300 BTU/h at their median CEER would cost about $61.50 for 30 days at 8 hours, $6.07 more than this one.

Questions

What is the GUNJI GJ1309PAC14's real BTU?
It's certified to DOE at 10,300 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 450 sq ft. ENERGY STAR's sizing chart calls for 10,000 BTU/h in rooms up to 450 sq ft. A sunny room, a kitchen or a high ceiling needs more.
How much does the GUNJI GJ1309PAC14 cost to run for 8 hours?
About $1.85 for 8 hours of cooling: roughly 1,272 W at 18.16¢/kWh, the US residential average for August 2026 (EIA).
