The ETENWOLF P200 is a cordless electric ball pump built for sports balls — not tires. Running on a 2,000 mAh / 7.4 Wh battery, it inflates a size-7 basketball from 0 to 8 PSI in 57 seconds and delivers 68 full inflations per charge. Maximum output pressure is 17 PSI, which covers every common ball sport; the ±0.5 PSI auto-shutoff stops inflation precisely at your target. A deflation mode operates at 6.5 L/min through a dedicated port.

Core Performance Specifications
The P200 delivers 6.5 L/min of airflow at zero back-pressure and reaches 17 PSI maximum output — enough for every common sport ball. Its auto-shutoff accuracy of ±0.5 PSI (full range, all modes) stops inflation within half a PSI of your target. The 2,000 mAh / 7.4 Wh Hongli-brand battery charges fully in approximately 68 minutes via PD USB-C 10 W.

Ball Compatibility & Standard Pressures
The P200 covers a pressure range of 2–17 PSI, which encompasses all major ball sports. Its 17 PSI maximum is not sufficient for car tires (200+ kPa / 29+ PSI) or bicycle tires (60+ PSI).
| Ball Type | Standard Pressure Range | P200 Compatible? |
|---|---|---|
| Basketball (NBA) | 7.5–8.5 PSI | Yes |
| Soccer / Football (FIFA) | 8.7–11.6 PSI | Yes |
| Volleyball | 4.3–4.6 PSI | Yes |
| American Football (NFL) | 12.5–13.5 PSI | Yes |
| Tennis ball | — | Yes |
| Car / truck tires | 29–51 PSI (200–350 kPa) | No — max 17 PSI |
| Bicycle tires | 60–130 PSI | No — max 17 PSI |
P200 vs P300 vs P300 Plus — Series Comparison
All three ball pumps share the same 6.5 L/min flow rate, ±0.5 PSI accuracy, and 245 g weight. The primary differences are battery size (P200: 2,000 mAh; P300: 2,600 mAh; P300 Plus: 3,200 mAh) and minor exterior design — there are no performance differences between models.

Frequently Asked Questions
Can the P200 inflate a basketball to NBA standard (8 PSI)? How long does it take?
Yes. The P200 inflates a size-7 basketball from 0 PSI to 8 PSI in 57 seconds at 25 °C with a full battery, auto-stopping within ±0.5 PSI of the 8 PSI target. Per charge (2,000 mAh) it can perform 68 full inflations (0→8 PSI).
How many basketballs can the P200 inflate on one charge?
68 full inflations of a size-7 basketball from 0 to 8 PSI on a single 2,000 mAh charge (tested at 25 °C). For soccer balls (0→9 PSI) the count is 50; for American footballs (0→12 PSI) it is 63.
Does the P200 have auto-shutoff? What is the accuracy?
Yes. The P200 auto-stops at the target pressure with ±0.5 PSI accuracy across the full 2–17 PSI range and all modes. This accuracy is maintained even below 20% battery level.
Does the P200 support deflation?
Yes. Select deflate mode on the pump, then insert the needle into the deflate port (not the inflation port). Deflation speed is 6.5 L/min.
Can the P200 inflate soccer, volleyball, and football?
Yes — all common sports balls within the 2–17 PSI range are supported. Soccer ball (size 5, 0→9 PSI): 1 min 15 s. American football (0→12 PSI): 1 min. Volleyball (4.5 PSI): faster than basketball. The 17 PSI maximum does not cover car or bicycle tires.
Can the P200 inflate car tires?
No. Car tires require 29–51 PSI (200–350 kPa). The P200’s maximum output is 17 PSI — it is a ball pump only. For tire inflation see the ETENWOLF S1 or S5.
What is the difference between the P200, P300, and P300 Plus?
All three models have identical flow rate (6.5 L/min), accuracy (±0.5 PSI), and weight (~245 g). The only differences are battery capacity (P200: 2,000 mAh; P300: 2,600 mAh; P300 Plus: 3,200 mAh) and exterior appearance. Choose based on how many balls you need to inflate per session.
