Test Equipment & Setup
| Parameter | Specification / Value |
|---|---|
| Load pressure | 40 psi (continuous) |
| Initial battery state | Fully charged |
| Ambient temperature condition | ≥ 30 °C (room temperature) |
| Measured ambient temperature | 32.0 °C (both samples) |
| Monitored parameters | Battery temperature (°C), Motor temperature (°C), Ambient temperature (°C) |
| Test duration (unit 2#) | 30 minutes — test stopped at 30 min |
| Test duration (unit 3#) | 30 minutes — unit reported error E14, test stopped |
Test Procedure
- Pre-test: Ensure the sample is at room temperature and fully charged.
- Environment check: Confirm ambient temperature is ≥ 30 °C before starting.
- Setup: Connect the inflator to a 40 psi load.
- Run: Operate the product continuously at 40 psi load until battery is depleted or the test is otherwise stopped.
- Monitoring: Record battery temperature and motor temperature throughout the run.
- Stop conditions: Stop at 30 minutes of operation, or immediately if the unit raises an error code (e.g., E14).
- Post-test: Record peak temperatures and calculate temperature rise (K) relative to ambient.
- Acceptance criteria: No formal pass/fail threshold applied — results issued for reference only.
Test Data & Results
| Sample No. | Item | Battery Temperature (°C) | Motor Temperature (°C) | Ambient Temperature (°C) | Remarks |
|---|---|---|---|---|---|
| 2# | Peak Temperature (°C) | 70.0 | 62.8 | 32.0 | Test stopped after 30 minutes |
| 2# | Temperature Rise (K) | 38.0 | 30.8 | — | — |
| 3# | Peak Temperature (°C) | 75.1 | 65.6 | 32.0 | Unit reported error E14 after 30 minutes; test stopped |
| 3# | Temperature Rise (K) | 43.1 | 33.6 | — | — |
Observations: Unit 2# ran for the full 30-minute window without fault. Unit 3# triggered error code E14 at the 30-minute mark, halting the test automatically. Both units exhibited battery temperatures above 70 °C, which is consistent with high-duty-cycle cordless inflator operation. Detailed time-series measurements are contained in the companion sheet (温升测试数据 / Thermal Test Data).

Frequently Asked Questions
What temperatures did the S7 battery and motor reach during the thermal rise test?
Under a 40 psi continuous load with a fully charged battery at 32 °C ambient, the S7 battery peaked at 75.1 °C (temperature rise 43.1 K) and the motor peaked at 65.6 °C (temperature rise 33.6 K) in the higher-reading sample (unit 3#). Unit 2# recorded 70.0 °C battery and 62.8 °C motor temperatures.
What does the E14 error code mean on the ETENWOLF S7 inflator?
During this thermal test, unit 3# triggered error code E14 after 30 minutes of continuous operation at 40 psi. E14 is a protection fault — most likely an over-temperature or over-load cut-off — that halted the unit automatically. The test was stopped at that point per the test protocol.
Did the S7 pass the thermal rise test?
No pass or fail verdict was issued. The report is designated For Reference Only, meaning the data is used to characterise thermal behaviour under worst-case continuous-run conditions rather than to certify compliance with a specific temperature limit standard.
How long did the S7 run continuously at 40 psi during this test?
Both samples were operated for 30 minutes at 40 psi with a fully charged battery. Unit 2# reached the 30-minute mark without fault; unit 3# reached 30 minutes before triggering error E14. Neither unit depleted its battery within the 30-minute window.
