Key Findings
All four S7 bare-unit samples completed the full 6-face drop sequence from 80 cm without functional failure; two units exhibited minor front/rear housing misalignment on four faces, while all units retained normal operating function throughout.
- Product: ETENWOLF Vortex S7 Tire Inflator (bare unit)
- Drop Height: 80 cm (per ISTA / IEC packaging drop protocol)

Test Equipment & Setup
| Parameter | Value |
|---|---|
| Drop Height | 80 cm |
| Drop Surface | Standard rigid flat surface (per drop test protocol) |
| Unit Configuration | Bare unit — no outer packaging, no accessories |
| Number of Faces | 6 |
| Drop Sequence | Face 1: Back → Face 2: Right Side → Face 3: Front → Face 4: Left Side → Face 5: Bottom → Face 6: Top |
| Post-Drop Functional Check | Visual inspection + operational function verification after each face drop |
| Sample IDs | 5#, 6#, 7#, 8# |
Test Procedure
- Pre-Test: Visually inspect each sample and confirm normal function before testing. Record sample IDs (5#, 6#, 7#, 8#).
- Setup: Place unit in the specified face-down orientation at a drop height of 80 cm above the rigid flat surface, with no packaging.
- Drop — Face 1 (Back face down): Release unit from 80 cm; allow free fall. Immediately inspect for physical damage and verify operational function.
- Drop — Face 2 (Right side face down): Repeat drop procedure from 80 cm with right side oriented downward. Inspect and verify function.
- Drop — Face 3 (Front face down): Repeat drop procedure from 80 cm with front face oriented downward. Inspect and verify function.
- Drop — Face 4 (Left side face down): Repeat drop procedure from 80 cm with left side oriented downward. Inspect and verify function.
- Drop — Face 5 (Bottom face down): Repeat drop procedure from 80 cm with bottom face oriented downward. Inspect and verify function.
- Drop — Face 6 (Top face down): Repeat drop procedure from 80 cm with top face oriented downward. Inspect and verify function.
- Post-Test: Record all observations for each face and each sample. Classify results as: no anomaly, cosmetic anomaly only, or functional failure.
- Acceptance Criteria: No functional failure is permitted. Minor cosmetic anomalies (e.g., housing misalignment without loss of function) are noted but do not constitute a test failure.
Test Data & Results
| Test Date | Sample No. | Drop 1 — Back Face Down | Drop 2 — Right Side Face Down | Drop 3 — Front Face Down | Drop 4 — Left Side Face Down | Drop 5 — Bottom Face Down | Drop 6 — Top Face Down |
|---|---|---|---|---|---|---|---|
| 2025-03-11 | 5# | No anomaly | No anomaly | Front/rear housing misalignment; function normal | Front/rear housing misalignment; function normal | Front/rear housing misalignment; function normal | Front/rear housing misalignment; function normal |
| 6# | No anomaly | No anomaly | No anomaly | No anomaly | No anomaly | No anomaly | |
| 7# | No anomaly | No anomaly | No anomaly | No anomaly | No anomaly | No anomaly | |
| 8# | No anomaly | No anomaly | Front/rear housing misalignment; function normal | Front/rear housing misalignment; function normal | Front/rear housing misalignment; function normal | Front/rear housing misalignment; function normal |
Observations: Units 5# and 8# exhibited front/rear housing misalignment beginning at the front-face drop (Face 3) and persisting through all remaining faces. In both cases operational function was confirmed as normal immediately after each drop. Units 6# and 7# showed no anomaly across all six faces. No unit suffered any functional failure during the test sequence.
Note on test date encoding: The raw data field contains the value 45454.0, which is the Excel serial date corresponding to 2025-03-11.

Frequently Asked Questions
What does the ETENWOLF S7 bare-unit drop test measure?
The bare-unit drop test evaluates the S7 tire inflator’s mechanical durability when dropped from 80 cm onto a rigid surface across all six faces — back, right side, front, left side, bottom, and top — without any protective packaging. It checks for functional failures and cosmetic damage after each drop.
Did any S7 unit fail the 6-face drop test?
No. All four units (5#, 6#, 7#, 8#) passed the test with zero functional failures. Units 5# and 8# showed minor front/rear housing misalignment on four faces each, but normal operation was confirmed after every drop.
What is considered a pass or fail in the S7 drop test?
A unit fails if it suffers a functional failure — meaning the inflator no longer operates correctly after a drop. Cosmetic anomalies such as housing misalignment, with no impact on function, are recorded as observations but do not cause a test failure.
How many faces and what drop height were used for the S7 drop test?
The S7 bare-unit drop test used a drop height of 80 cm and covered 6 faces: back face down, right side face down, front face down, left side face down, bottom face down, and top face down — one free-fall drop per face per sample.
