Answer
Can the Honda EU3000iS run BLACK+DECKER BDM05C 5,000 Btu/h window air conditioner?
Runs
Runs. Running draw 347 W fits within 2,800 running watts. Startup watts were not published; 3,000 starting watts is at least 3× the running draw, the common planning allowance for a compressor or pump start.

Questions
Can the Honda EU3000iS run BLACK+DECKER BDM05C 5,000 Btu/h window air conditioner?
Runs. Running draw 347 W fits within 2,800 running watts. Startup watts were not published; 3,000 starting watts is at least 3× the running draw, the common planning allowance for a compressor or pump start.
What watts were compared?
Generator: 2,800 running W and 3,000 starting W on gasoline. Appliance: 347 W running, startup not published.
How long will it run?
Fuel runtime depends on total load. Published runtime: 6.9 hr at rated load, 19.6 hr at 1/4 load.
Where did the numbers come from?
Honda spec table: 120V 3000W max (25A), 2800W rated (23.3A); 20A duplex and 30A 125V locking receptacle; 3.4 gal; 6.9 hr rated / 19.6 hr 1/4 load; 57/50 dB(A); 130.7 lb dry. The 30A outlet is an L5-30R, not a TT-30R. ENERGY STAR lists 5,000 Btu/h, CEER 14.4, 115 V, variable-speed compressor, and 260.4 kWh/year. Rated input is 5,000 ÷ 14.4 = 347.2 W. That matches the listed annual energy at the DOE room-AC assumption of 750 hours (347.2 × 750 ÷ 1,000 = 260.4). The 347.2 W figure is the draw while cooling at the rated condition, not a whole-year average. Startup watts are not published.
Safety first
- Run a generator outdoors only, at least 20 feet from the house, with the exhaust pointed away from doors, windows and vents. Never in a garage, basement, shed or crawlspace, even with the door open.
- Carbon monoxide is odorless and can kill in minutes. Keep battery CO alarms working inside the home.
- Never backfeed a house by plugging a generator into a wall outlet or dryer receptacle. It can energize utility lines and kill a lineworker or a neighbor.
- Connecting to home wiring requires a transfer switch or a listed breaker interlock with a power inlet box, installed by a licensed electrician and permitted where your jurisdiction requires it.
