Test Equipment & Setup
| Item | Detail |
|---|---|
| Test Equipment | Thermal Rise Tester — Thermocouple Type K (温升测试仪，热电偶K型) |
| Load Condition | 35–40 psi (continuous load from startup) |
| Operating Mode | Unit powered on at indoor ambient temperature and run continuously until battery fully discharged |
| Measurement Points | Motor, Battery, Cylinder, Air-hose nozzle junction, Air-hose tail end, Laboratory ambient |
| Evaluation Criterion | Assess performance stability of sample temperature variation (评估样品温度变化的性能稳定性) |
Test Procedure
- Pre-test: Place samples in indoor environment and allow to stabilize at ambient temperature (26.0 °C). Confirm battery is fully charged. Attach thermocouple probes (Type K) to each measurement point: motor, battery, cylinder, air-hose nozzle junction, and air-hose tail end.
- Load setup: Connect the inflator hose to a pressure load target set at 35–40 psi.
- Operation: Power on the S1 inflator and run continuously under the 35–40 psi load while logging temperature data at each measurement point.
- Run to completion: Continue operation until the battery is fully discharged.
- Data collection: Record peak (maximum) temperature and temperature rise (ΔT in Kelvin, calculated as peak temperature minus ambient temperature) for each measurement point on each sample.
- Post-test: Allow the unit to cool. Document observations and photos of internal wiring configuration and unit in operation.
Acceptance Criterion: This test is conducted for reference purposes (供参考). Results are used to evaluate thermal stability and potential overheating risk; no pass/fail threshold is defined in the internal standard for this evaluation cycle.
Test Data & Results
| Sample No. | Measurement | Motor | Battery | Cylinder | Air-Hose Nozzle Junction | Air-Hose Tail End | Lab Ambient |
|---|---|---|---|---|---|---|---|
| S1-1# | Peak Temperature (°C) | 57.2 | 63.2 | 72.9 | 87.3 | 52.6 | 26.0 |
| S1-1# | Temperature Rise (K) | 31.2 | 37.2 | 46.9 | 61.3 | 26.6 | — |
| S1-3# | Peak Temperature (°C) | 58.6 | 57.5 | 69.6 | 85.3 | 51.8 | 26.0 |
| S1-3# | Temperature Rise (K) | 32.6 | 31.5 | 43.6 | 59.3 | 25.8 | — |
Observations: Across both samples the air-hose nozzle junction consistently recorded the highest peak temperature and the largest temperature rise — 87.3 °C / 61.3 K for S1-1# and 85.3 °C / 59.3 K for S1-3#. The motor and air-hose tail end were the coolest monitored components. Both samples showed closely comparable thermal profiles, indicating consistent manufacturing. Full time-series temperature change data is available in the companion sheet 温升变化数据. Test photos include images of internal wiring and the unit during operation.

Frequently Asked Questions
What is the maximum operating temperature of the ETENWOLF S1 tire inflator?
Based on this thermal rise test, the hottest point on the S1 is the air-hose nozzle junction, which peaked at 87.3 °C on sample S1-1# and 85.3 °C on sample S1-3# during a full-discharge run at 35–40 psi. Always allow the unit to cool before handling the hose nozzle area after extended use.
How long does the ETENWOLF S1 run before the battery is fully discharged?
The thermal test ran each sample continuously at 35–40 psi load until the battery was fully discharged, and full time-series data is captured in the companion 温升变化数据 sheet. Exact runtime depends on battery state and ambient conditions; refer to the product page for rated run-time specifications.
Which component heats up the most during S1 inflator operation?
The air-hose nozzle junction recorded the highest temperature and temperature rise across both test samples — reaching up to 87.3 °C with a rise of 61.3 K above the 26.0 °C ambient. The motor and air-hose tail end remained the coolest monitored components.
What test standard does the ETENWOLF S1 thermal test follow?
This test follows ETENWOLF’s internal reliability standard. The evaluation criterion is to assess performance stability of temperature variation and identify potential overheating risks. No third-party standard such as IEC or UL is applied to this particular evaluation cycle; the result is designated for reference only.
