Test Procedure
- Pre-test: Confirm sample unit is P200-1#. Verify pump firmware and pressure sensor are functional. Deflate the target ball to below the starting pressure of the test range.
- Setup: Connect the appropriate needle adapter for the ball type under test. Set the target preset pressure on the P200 pump interface to the upper limit of the specified test range.
- Inflation: Activate the pump. Allow it to inflate the ball and auto-stop when the preset pressure is reached.
- Measurement: Record the actual stop pressure (PSI) displayed or measured at shutoff.
- Deviation Calculation: Calculate deviation as Actual Stop Pressure minus Preset Pressure. Record the result.
- Repeat: Deflate the ball, change the preset range as required, and repeat for all specified pressure ranges across all ball types.
- Post-test: Compile all results and compare deviations against the acceptance criterion.
Acceptance Criterion: Deviation between actual stop pressure and preset pressure must be within ±0.5 PSI across all test conditions.

Observations: All 27 recorded test runs produced deviations at or below −0.3 PSI. The largest single deviation was −0.3 PSI observed on American Football at the 1–3 PSI range (Row 16). Deviations of −0.1 PSI were the most common non-zero result, occurring across basketball, American football, soccer, and volleyball. No positive over-inflation deviation was recorded in any run. Rows numbered 1, 10, 21, 28 are absent from the source data (likely reserved for header groupings or intentionally skipped in the original worksheet); all rows present in the source have been included without omission. Note: The source data contains 27 data rows (rows numbered 2–31 with gaps); the raw JSON reports row_count as 30 including header rows.
Conclusion
| Parameter | Detail |
|---|---|
| Result | PASS |
| Acceptance Criterion | Deviation within ±0.5 PSI at all preset pressures |
| Maximum Deviation Recorded | −0.3 PSI (American Football, 1–3 PSI range, Row 16) |
| Test Conditions | 4 ball types; pressure ranges 1–11 PSI; 27 test runs |
| Sample | P200-1# |
| Test Date | 2025-03-19 |
| Verdict | The ETENWOLF P200 Electric Ball Pump (Sample 1#) meets the inflation accuracy requirement. All actual stop pressures fell within ±0.3 PSI of the preset target, well inside the ±0.5 PSI acceptance threshold. |

Frequently Asked Questions
How accurate is the ETENWOLF P200 Electric Ball Pump at stopping at the preset pressure?
In Sample 1# testing across 27 runs covering basketball, American football, soccer, and volleyball from 1 to 11 PSI, the P200 stopped within ±0.3 PSI of every preset target. The average deviation was less than 0.1 PSI, and 17 of 27 runs recorded zero deviation. This performance is well within the ±0.5 PSI acceptance criterion.
Which ball types were tested for inflation accuracy on the P200?
The P200精度-1# sheet covers four ball types: basketball (8 runs, 2–9 PSI), American football (8 runs, 1–11 PSI), soccer (6 runs, 1–7 PSI), and volleyball (3 runs, 1–4 PSI). Sibling sheets P200精度-2# and P200精度-3# cover additional samples using the same methodology.
What is the largest pressure deviation recorded for the P200 in this test?
The largest deviation was −0.3 PSI, recorded during the American football test at the 1–3 PSI range (preset 3 PSI, actual stop 2.7 PSI, test row 16). All other deviations were 0.0 or −0.1 PSI. No over-inflation (positive deviation) was observed in any test run on this sample.
Does the P200 inflate different ball types with equal accuracy across the pressure range?
Yes. The P200 demonstrated consistent accuracy across all four ball types tested. Deviations were small and unidirectional (the pump slightly under-shoots at the lower end of some ranges), and no ball type showed systematic inaccuracy. The worst-case −0.3 PSI deviation occurred once, at the lowest pressure range tested for American football.
