Test Equipment & Setup
| Item | Detail |
|---|---|
| Measurement instrument | Thermal rise tester with Type-K thermocouple |
| Load condition | 35–40 psi (continuous run until battery discharged) |
| Ambient environment | Indoor, ambient temperature 29.6 °C |
| Measurement points | Motor, cylinder joint, air tube, battery bottom, battery middle, battery top |
| Data collection method | Continuous thermocouple logging; full dataset on sibling sheet 温升采集数据 |
Test Procedure
- Pre-test: Record laboratory ambient temperature (29.6 °C). Verify sample identity (8# and 9#). Attach Type-K thermocouples to all six measurement points: motor, cylinder joint, air tube, battery bottom, battery middle, and battery top.
- Setup: Connect samples to a load maintaining 35–40 psi back-pressure. Confirm thermocouple logger is active and recording.
- Run: Power on each sample and run continuously under load until the battery is fully discharged. Do not interrupt the run; log temperature data at all points throughout the entire discharge cycle.
- Event monitoring: Note any fault codes or anomalies. (Sample 8# triggered an E14 error during the run.)
- Post-test: Record peak temperatures and calculate temperature rise (ΔT = T_peak − T_ambient) for each measurement point on each sample.
- Acceptance criterion: Evaluate performance stability of temperature variation across the discharge cycle. Results to be issued as Pass, Fail, or For Reference Only based on observed thermal behavior.
Test Data & Results
| Sample ID | Metric | Motor | Cylinder Joint | Air Tube | Battery Bottom | Battery Middle | Battery Top | Lab Ambient (°C) |
|---|---|---|---|---|---|---|---|---|
| C2PV-8# | Peak Temperature (°C) | 88.7 | 140.8 | 79.5 | 96.2 | 82.0 | 76.1 | 29.6 |
| C2PV-8# | Temperature Rise (K) | 59.1 | 111.2 | 49.9 | 66.6 | 52.4 | 46.5 | — |
| C2PV-9# | Peak Temperature (°C) | 75.6 | 128.9 | 80.2 | 82.6 | 73.6 | 66.9 | 29.6 |
| C2PV-9# | Temperature Rise (K) | 46.0 | 99.3 | 50.6 | 53.0 | 44.0 | 37.3 | — |
Observations: The cylinder joint was the hottest location on both samples, reaching 140.8 °C (ΔT 111.2 K) on 8# and 128.9 °C (ΔT 99.3 K) on 9#. The battery bottom was the second-highest thermal zone. Sample 8# triggered an E14 fault code during the run. Full time-series acquisition data is available on the companion sheet (温升采集数据).

Frequently Asked Questions
What does the E14 error code mean on the ETENWOLF C2PV inflator?
E14 is a fault code that appeared on sample 8# during the full-discharge thermal run. Based on the test context it is associated with an abnormal condition detected during continuous high-load operation. If you see E14 during normal use, stop inflation, allow the unit to cool, and contact ETENWOLF support for further diagnosis.
How hot does the ETENWOLF C2 inflator get during continuous use?
Under a 35–40 psi continuous load run to full battery discharge, the cylinder joint reached up to 140.8 °C (temperature rise of 111.2 K above the 29.6 °C ambient) on the tested sample. The motor reached up to 88.7 °C and the battery bottom up to 96.2 °C. These figures are engineering reference values from a worst-case endurance scenario and are not representative of typical short-duration inflation cycles.
Why is this thermal test result marked For Reference Only rather than Pass or Fail?
The test was conducted against an internal performance-stability criterion rather than a specific numeric pass/fail threshold. Because one sample also triggered a fault (E14) during the run, the engineering team classified the outcome as for reference only, meaning the data informs product development decisions without constituting a formal compliance verdict.
Which measurement point shows the highest thermal rise on the C2PV inflator?
The cylinder joint consistently shows the highest temperature rise on both samples — 111.2 K on sample 8# and 99.3 K on sample 9#. This makes the cylinder joint the primary thermal management focus point for the C2PV design.
