The ETENWOLF P400 is a 660 W AC-powered electric balloon pump that moves 450 L/min of air — inflating a standard 11-inch latex balloon in approximately 5 seconds. It runs on AC 110 V (no 220 V version) and offers two operating modes: Touch-on (press and hold) and Auto (hands-free). Important: The P400 inflates with air, not helium — balloons will not float. It does not support 260Q long/twisting balloons due to pressure limitations; for those, the P600 is required. Maximum continuous operation is 2 hours before risk of motor overheating.

Important: Air Only — Balloons Will NOT Float
The P400 inflates balloons with ordinary air — not helium or hydrogen. Air-filled balloons are heavier than air and will not float or rise to the ceiling. If floating balloons are required, a helium tank and regulator are needed; the P400 is not suitable for that purpose.
Core Performance Specifications
The P400’s 660 W single motor delivers 450 L/min at zero back-pressure on AC 110 V. Measured noise levels at 1 m distance ranged from 78.4 to 82.2 dB(A) across three test conditions. The unit ships in three colors (Orange, Purple, Blue) with identical internal specifications; launched January 2025.

2 Nozzle Types
The P400 ships with two nozzle types, both attaching by threading onto the pump outlet. The long-balloon nozzle is included for foil (mylar) balloons; the round nozzle covers standard latex balloons.
| Nozzle | Balloon Type | Attachment |
|---|---|---|
| Foil balloon nozzle | Long-strip foil (mylar) balloons | Thread onto outlet |
| Round balloon nozzle | Standard round latex & foil balloons | Thread onto outlet |
Balloon Compatibility
The P400’s pressure output covers round latex and most foil balloons. It cannot reach the pressure required for 260Q twisting/modeling balloons; use the P600 for those.
| Balloon Type | P400 Compatible? | Notes |
|---|---|---|
| 11-in round latex (standard) | Yes (~5 s) | Most common party balloon |
| 14-in round latex | Yes | Slightly longer fill time |
| 18-in foil / mylar | Yes | Use foil balloon nozzle |
| 260Q twisting / modeling balloons | No | Requires higher pressure — use P600 |
P400 vs P600 — Which Should You Choose?
The P400 (450 L/min, 660 W, single motor) suits home use and small events; the P600 (850 L/min, 600 W, dual motor with high-pressure stage) is ~89% faster in raw flow rate, supports 260Q twisting balloons through its high-pressure motor, and includes 4 nozzle types vs 2. Noise levels are similar: P400 at 78–82 dB(A) vs P600 at 82–85 dB(A).
| Spec | P400 | P600 |
|---|---|---|
| Airflow | 450 L/min | 850 L/min |
| Motor | 660 W, single | 600 W, dual (incl. high-pressure) |
| Long / 260Q balloons | Not supported | Supported (3-mode pressure) |
| Nozzle types | 2 | 4 |
| Noise (1 m) | 78–82 dB(A) | 82–85 dB(A) |
| Max continuous use | 2 hr | 2 hr |
| Best for | Home / small parties (<100 balloons) | Weddings / large events / all balloon types |

Frequently Asked Questions
Will P400-inflated balloons float?
No. The P400 inflates balloons with ordinary compressed air, not helium or hydrogen. Air is denser than air at room temperature; air-filled balloons sink to the floor. For floating balloons, a helium tank and regulator are required — the P400 cannot produce helium.
Can the P400 inflate 260Q twisting / modeling balloons?
No. 260Q long/twisting balloons require significantly higher pressure than round latex balloons, and the P400’s single motor does not reach that pressure level. The ETENWOLF P600 (dual motor with high-pressure stage) supports 260Q balloons through its dedicated twisting-balloon mode.
How long does it take to inflate a 11-inch balloon? How many per hour?
Approximately 5 seconds per 11-inch round latex balloon at standard inflation. Continuous operation for up to 2 hours is safe before motor overheating risk increases. Exact hourly count depends on mode and rest intervals.
P400 vs P600 — which is right for my event?
Choose the P400 for home birthday parties, small gatherings, and events where only round or foil balloons are needed. Choose the P600 for weddings, corporate events, professional balloon artists, or any event requiring 260Q twisting balloons — the P600 is 89% faster (850 vs 450 L/min) and supports all balloon types.
How long can I run the P400 continuously?
Maximum recommended continuous operation is 2 hours. Beyond 2 hours, the motor may overheat and sustain damage. After 2 hours of use, allow the unit to cool before continuing.
Does the P400 work outside the US (220 V)?
No. The P400 is rated for AC 110 V only. There is no 220 V version. Using it on 220 V circuits without a step-down transformer will damage the unit.
