Test Overview

Test Equipment & Setup

Test Procedure

1. Pre-test: Confirm the P300 unit is fully charged and in working condition. Select the correct ball-type mode on the device display.
2. Pre-test: Deflate the test ball to the starting pressure indicated in the "Inflation Range" column (e.g., 0 PSI, 1 PSI, 2 PSI, etc.).
3. Setup: Connect the P300 inflation needle to the ball valve. Set the preset target pressure on the device to the value specified in the "Preset Pressure" column.
4. Inflation: Activate the pump. The device inflates the ball automatically and stops when the internal pressure sensor detects the preset value has been reached.
5. Measurement: Record the actual stop pressure (PSI) displayed or measured at the moment the pump cuts off.
6. Calculation: Calculate deviation = Stop Pressure − Preset Pressure. Record in the "Deviation (Accuracy)" column.
7. Post-test: Deflate the ball to the next starting pressure and repeat for all test cases listed in the data table.
8. Acceptance Criteria: The pump passes if all stop pressures are within ±0.1 PSI of the preset target pressure across all ball types and inflation ranges.

Test Data & Results

Observations: Of 31 test cases, 8 recorded a deviation of ±0.1 PSI and 23 recorded a deviation of exactly 0 PSI. The largest deviations (−0.1 PSI) occurred at the lowest inflation range (0–2 PSI) for both basketball and rugby, which is consistent with initial pressure-sensor calibration behavior at near-zero starting pressures. All deviations are within the ±0.1 PSI acceptance criterion. No anomalies or out-of-range readings were recorded.

Frequently Asked Questions

How accurate is the ETENWOLF P300 Smart Ball Pump?

In standardized inflation accuracy testing across 31 test cases covering basketballs, rugby/American footballs, soccer balls, and volleyballs, the P300 achieved stop pressures within ±0.1 PSI of every preset target. The majority of tests recorded zero deviation, with the small ±0.1 PSI deviations concentrated at the lowest pressure ranges.

What ball types does the ETENWOLF P300 support?

The P300 includes dedicated inflation modes for basketball, rugby/American football, soccer, and volleyball. Each mode is calibrated to the appropriate pressure range for that sport, with preset pressure targets from as low as 2 PSI up to 10.9 PSI depending on the ball type.

What is the maximum preset pressure the P300 can reach for sports balls?

Based on the P300-1# inflation accuracy test, the highest preset target tested was 10.9 PSI, used for rugby/American football. The pump stopped at 10.8 PSI in both test cases at that target, a deviation of −0.1 PSI, which is within the accepted accuracy tolerance.

Does the P300 automatically stop when the target pressure is reached?

Yes. The P300 uses an internal pressure sensor to monitor inflation in real time and automatically cuts off the motor when the preset target pressure is reached. This auto-stop feature was validated across all 31 test cases in the P300-1# accuracy test with no overshoot beyond ±0.1 PSI.
