How much does the LEMBERI 10K-PAC-WHT cost to run?

About 17¢ an hour of cooling, or $39.62 for 30 days at 8 hours a day (less once the compressor cycles off).

6,000 BTU/h SACC divided by a CEER of 6.6 is about 909 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 7¢.

How does the LEMBERI 10K-PAC-WHT rank in its DOE class?

In its DOE class (single hose portable ACs), 171 models have a matched Amazon listing. 123 of them have a higher CEER than its 6.6, which is 10% below their median of 7.3. On cost, the same 6,000 BTU/h at their median CEER would cost about $35.82 for 30 days at 8 hours, $3.80 less than this one.

Questions

What is the LEMBERI 10K-PAC-WHT's real BTU?
It's certified to DOE at 6,000 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 250 sq ft. ENERGY STAR's sizing chart calls for 6,000 BTU/h in rooms up to 250 sq ft. A sunny room, a kitchen or a high ceiling needs more.
How much does the LEMBERI 10K-PAC-WHT cost to run for 8 hours?
About $1.32 for 8 hours of cooling: roughly 909 W at 18.16¢/kWh, the US residential average for August 2026 (EIA).
