Power setup is one of the most common day-of-event problems for inflatable rental operators — an undersized extension cord, a tripped GFCI outlet, or a shared circuit with too many devices causes blower failure mid-event and unhappy clients. Understanding the electrical requirements of your inflatables before every setup eliminates 95% of power-related issues.
Quick Answer
A standard 1 HP bounce house blower draws 8–12 amps on a 120V circuit. Use 12-gauge or heavier extension cord rated for outdoor use, no longer than 100 feet. Never share a circuit with another high-draw appliance. Always connect to a GFCI outlet or use an inline GFCI adapter.
🎯 Key Takeaways
- 1 HP blower draws 8–12 amps; 1.5 HP draws 12–15 amps; 2 HP draws 15–20 amps — never exceed 80% of circuit capacity
- Extension cord gauge matters: use 12 gauge for 50 ft, 10 gauge for 100 ft — undersized cord causes voltage drop and motor damage
- Always test the outlet before inflating — bring a plug-in outlet tester to every event (costs $8 at hardware stores)
- GFCI protection is required near water (water slides, wet events) by the NEC — never skip this at water events
- A portable Honda or Yamaha generator (2,000–3,000W) handles 1–2 blowers at events without outlet access
Blower Power Requirements by Size
| Blower Size | Amps Drawn | Cord Gauge (100 ft) |

| 3/4 HP | 7–9 A | 12 gauge min. |
| 1 HP | 8–12 A | 12 gauge min. |
| 1.5 HP | 12–15 A | 10 gauge min. |
| 2 HP | 15–20 A | 10 gauge (50 ft max) |
