Test Procedure
- Pre-Test: Confirm tire is a 215/55 R17 size. Deflate to 25 psi baseline before each run. Verify C2PV unit is fully charged or connected to power source per operating spec.
- Connection: Attach the C2PV inflator nozzle securely to the tire valve stem. Confirm no air leakage at the connection.
- Inflation Start: Start the timer simultaneously with activating the C2PV inflator.
- Monitoring: Allow the unit to inflate continuously until the onboard pressure gauge reads 35 psi.
- Inflation Stop: Stop the timer the moment the inflator reaches 35 psi and automatically halts, or is manually stopped at target pressure.
- Record: Log the elapsed time (MM:SS) for the completed run.
- Reset: Deflate tire back to 25 psi and allow the unit a standardized rest interval before the next run.
- Repeat: Perform steps 2–7 for 10 total runs per unit. Repeat full sequence for Unit 2#.
- Post-Test: Review all 20 recorded times for anomalies. Calculate per-unit averages and note the fastest and slowest runs.
Acceptance Criteria: All runs must complete successfully (inflator reaches 35 psi without failure). No acceptance threshold for maximum time was specified in this dataset; results are recorded for performance benchmarking.
Test Data & Results
| Unit | Run No. | Time (MM:SS) | Unit | Run No. | Time (MM:SS) |
|---|---|---|---|---|---|
| 1# | 1 | 02:51 | 2# | 1 | 02:48 |
| 1# | 2 | 02:56 | 2# | 2 | 02:25 |
| 1# | 3 | 02:45 | 2# | 3 | 02:42 |
| 1# | 4 | 03:05 | 2# | 4 | 02:47 |
| 1# | 5 | 02:42 | 2# | 5 | 03:08 |
| 1# | 6 | 02:49 | 2# | 6 | 03:27 |
| 1# | 7 | 03:05 | 2# | 7 | 02:41 |
| 1# | 8 | 03:06 | 2# | 8 | 02:43 |
| 1# | 9 | 02:34 | 2# | 9 | 02:42 |
| 1# | 10 | 02:56 | 2# | 10 | 03:03 |
Observations: Unit 1# showed consistent inflation times between 02:34 and 03:06, indicating stable motor output across repeated cycles. Unit 2# ranged from 02:25 to 03:27, with Run 6 being a notable outlier at 03:27. Both units completed all 10 runs without reported failure. The overall spread across all 20 runs is approximately 62 seconds, which is typical for consumer-grade portable tire inflators operating on a 10 psi load against a 215/55 R17 tire volume.

Frequently Asked Questions
How long does the ETENWOLF C2 take to inflate a 215/55 R17 tire from 25 to 35 psi?
In controlled testing across 20 runs on two units, the ETENWOLF C2 inflated a 215/55 R17 tire from 25 psi to 35 psi in approximately 02:25 to 03:27 (minutes:seconds), with a typical run completing in around 02:45 to 03:05.
Is the ETENWOLF C2 inflation time consistent across repeated uses?
Yes. Both test units completed 10 consecutive inflation cycles each without failure. Unit 1# showed particularly consistent results ranging from 02:34 to 03:06, while Unit 2# had a slightly wider spread of 02:25 to 03:27, with one outlier run at 03:27.
What tire size was used in the C2 inflation efficiency test?
The test used a 215/55 R17 passenger vehicle tire, which is a common mid-size tire found on sedans and crossovers. The pressure was measured from a starting point of 25 psi up to a target of 35 psi.
How many samples were tested in the ETENWOLF C2 inflation efficiency report?
Two C2PV units (designated 1# and 2#) were tested, each completing 10 inflation runs, for a total of 20 timed data points recorded on 2025-10-31.
