Real-World Examples

Residential / Events

A 70 kW generator could run:

• A large home or estate with all lights, appliances, and air conditioners running

• Dozens of inflatables, sound systems, and lighting for a large event

• 15–20 average U.S. homes’ worth of electricity during normal usage

Commercial

• Small to medium commercial building (e.g., small supermarket, office building, or restaurant with HVAC, refrigeration, and lighting)

• Construction site with multiple welders, air compressors, lighting towers, and small cranes

• Mobile event power for a full carnival ride setup (Ferris wheel, game booths, lighting, sound systems)

Industrial

• Multiple 3–5 HP motors running at once (pumps, fans, conveyors)

• Medium-size HVAC chiller system

• Backup for small manufacturing facility or server/data center

💡 Rule of Thumb for Event Use 
If we’re talking event rentals, a 70 kW generator can easily:

• Power 15–20 large inflatable bounce houses/slides at the same time

• Run mechanical rides (e.g., mechanical bull, rock wall, carnival rides)

• Provide lighting & sound for a full field festival without maxing out
