| Pressure Measurement Unit | PSI |
| Time Measurement Format | MM:SS (minutes and seconds) |
Test Procedure
- Pre-test preparation: Label three production-representative S7 units as 1#, 2#, and 3#. Verify each unit powers on normally and pressure display reads 0 PSI at rest.
- Baseline check: Confirm the inflation target is set to 40 PSI (passenger-car tyre mode). Record ambient temperature and humidity.
- Cycle execution: Begin continuous inflation cycles from 0 PSI to 40 PSI for all three samples simultaneously. Allow each unit to auto-stop at the preset 40 PSI target.
- Checkpoint measurement — pressure accuracy: At 4 h, 8 h, 12 h, 16 h, and 20 h of cumulative test duration, record the achieved cut-off pressure (PSI) displayed on each unit.
- Checkpoint measurement — inflation time: At each checkpoint, record the elapsed time (MM:SS) required for one complete 0–40 PSI inflation cycle for each sample.
- Intermediate observation: Inspect each unit for abnormal noise, overheating, leakage, or display malfunction. Note any anomaly.
- Test completion: After the 20-hour checkpoint, stop all units. Record final status as “Test Ended” (测试结束).
- Post-test inspection: Perform a visual and functional inspection of all three samples. Document any physical damage or performance degradation.
- Acceptance criteria: All samples must reach the 20-hour mark without functional failure. Pressure accuracy must remain within ±1 PSI of 40 PSI. Inflation time must remain within a stable range showing no significant degradation across checkpoints.
Test Data & Results
The table below contains all recorded data from the 0–40 PSI (passenger-car tyre) life test. Checkpoints are at 4-hour intervals. All six data columns are preserved exactly as captured.

| Test Ended — all three samples completed the full 20-hour endurance cycle | ||||||
Observations: Pressure accuracy across all samples and all checkpoints fell within the range of 39.8–40.6 PSI, representing a maximum deviation of ±0.6 PSI from the 40 PSI target. No progressive drift or degradation trend was observed. Inflation times remained stable between 03:37 and 03:56 across the entire 20-hour test, with no checkpoint showing a statistically significant increase in cycle time. No unit exhibited abnormal behaviour, noise, or failure at any point during the test.

Frequently Asked Questions
How long does the ETENWOLF S7 take to inflate a passenger-car tyre from 0 to 40 PSI?
Based on the life test data, the ETENWOLF S7 consistently inflated from 0 to 40 PSI in approximately 3 minutes 37 seconds to 3 minutes 56 seconds across all test checkpoints and all three sample units. This performance remained stable throughout the full 20-hour endurance test with no meaningful increase in cycle time.
How accurate is the ETENWOLF S7 pressure reading at 40 PSI?
Across all five checkpoints (4 h, 8 h, 12 h, 16 h, and 20 h) and all three samples, the S7 cut off within a range of 39.8–40.6 PSI when the target was set to 40 PSI. The maximum deviation observed was ±0.6 PSI, indicating consistent and reliable pressure accuracy throughout the product’s lifespan.
What does the ETENWOLF S7 life test cover?
The finished-product life test subjects three production S7 units to continuous 0–40 PSI inflation cycles for a total of 20 hours, simulating real-world passenger-car tyre use. Pressure accuracy and inflation time are recorded at 4-hour intervals to detect any performance degradation over the product’s service life.
Did the ETENWOLF S7 pass the 20-hour endurance test?
Yes. All three S7 samples completed the full 20-hour endurance cycle without any functional failure, abnormal noise, overheating, or display malfunction. Both pressure accuracy and inflation time remained stable from the first checkpoint at 4 hours through to the final checkpoint at 20 hours.
