Key Findings

All three P400 samples measured between 78.4 dB and 82.2 dB at 1 m (front-facing), tested across three nozzle configurations; results are recorded for reference only under the internal standard.

• Product: Electric Balloon Pump (气球充气泵), Model B7 / P400
• Report No.: 2025041701
• Test Date: 2025-04-17
• Samples: 3 units
• Measurement distance: 1 m from front face of unit
• Noise range across all configurations: 78.4 dB – 82.2 dB
• Highest reading: 82.2 dB (Sample 1#, 2 nozzles installed)
• Lowest reading: 78.4 dB (Sample 1#, no nozzle installed)
• Verdict: For Reference Only (供参考)

Test Overview

Test Equipment & Setup

Test Procedure

1. Pre-test: Verify ambient temperature (23 °C) and humidity (60 %). Confirm sound level meter calibration.
2. Sample preparation: Set up each of the 3 sample units in turn on a flat surface, front face oriented toward the microphone.
3. Microphone positioning: Place microphone at 1 m horizontal distance from the front face of the unit.
4. Configuration 1: Install two large nozzles on the unit, power on, and record noise reading in dB.
5. Configuration 2: Remove one nozzle so only one large nozzle is installed, power on, and record noise reading in dB.
6. Configuration 3: Remove all nozzles (bare unit), power on, and record noise reading in dB.
7. Repeat steps 4–6 for all three samples (1#, 2#, 3#).
8. Post-test: Power off all units. Record all readings and observations.

Acceptance Criteria: No formal pass/fail threshold defined. Results recorded for reference only (供参考) per internal standard.

Test Data & Results

Observations: Noise levels are consistently higher when more nozzles are attached. Sample 1# showed the widest variance across configurations (78.4–82.2 dB). Samples 2# and 3# were more consistent across configurations. No formal threshold is defined; all data is for reference only.

Frequently Asked Questions

How loud is the ETENWOLF P400 electric balloon pump?

In testing at 1 m from the front face, the P400 registered between 78.4 dB and 82.2 dB depending on the nozzle configuration and sample unit. The highest reading (82.2 dB) was recorded with two large nozzles attached; the lowest (78.4 dB) with no nozzle installed.

Does adding nozzles to the P400 increase its noise level?

Yes. Test data shows that installing more nozzles correlates with higher noise output. With two large nozzles attached, Sample 1# measured 82.2 dB, compared to 78.4 dB with no nozzle — a difference of 3.8 dB on the same unit.

What test standard was used for the P400 noise test?

The test was conducted to ETENWOLF’s internal standard. No external standard (such as IEC or ISO) was referenced, and no formal pass/fail threshold was defined. The results are recorded for reference only (供参考).

At what distance was noise measured for the P400 balloon pump test?

The sound level meter microphone was positioned at a horizontal distance of 1 m from the front face of the unit for all measurements.
