How much does the GOUKA GK-LB1-URF cost to run?

About 10¢ an hour of cooling, or $24.41 for 30 days at 8 hours a day (less once the compressor cycles off).

2,800 BTU/h SACC divided by a CEER of 5 is about 560 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 4¢.

How does the GOUKA GK-LB1-URF rank in its DOE class?

In its DOE class (single hose portable ACs), 171 models have a matched Amazon listing. 170 of them have a higher CEER than its 5, which is 32% below their median of 7.3. On cost, the same 2,800 BTU/h at their median CEER would cost about $16.72 for 30 days at 8 hours, $7.69 less than this one.

Questions

What is the GOUKA GK-LB1-URF's real BTU?
It's certified to DOE at 2,800 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 much does the GOUKA GK-LB1-URF cost to run for 8 hours?
About 81¢ for 8 hours of cooling: roughly 560 W at 18.16¢/kWh, the US residential average for August 2026 (EIA).
