Etenwolf P300 Electric Pump with 2600mAh Battery in Black

The Etenwolf P300 Electric Pump with 2600mAh Battery in Black is a compact, portable cordless inflation device designed to quickly and effortlessly prepare sports equipment and inflatables for use. Featuring a built-in rechargeable battery and a sleek black finish, this ergonomic pump delivers efficient performance with a flow rate of up to 6.5 l/min and support for pressures up to 17 PSI. It combines automatic preset modes, precise pressure monitoring, and dual inflation and deflation capabilities into a travel-ready construction, making it a reliable solution for athletes, coaches, and sports enthusiasts on the go.

Advantages

The device eliminates the physical effort of manual pumping by providing fully automatic inflation based on selected preset modes or custom pressure settings. Its sensitive pressure sensor and built-in gauge monitor the current pressure with an accuracy of ±0.3 PSI, preventing overinflation and ensuring consistent equipment performance. The high-capacity 2600mAh battery allows for up to 70 balls on a single charge, while the convenient USB-C port simplifies recharging. Furthermore, the compact construction includes integrated storage for two brass needles and exceptional durability confirmed by drop testing.

Suitable for

• Inflating basketballs, soccer balls, and footballs
• Adjusting pressure and deflating sports equipment
• Quick pre-game and pre-practice equipment preparation
• Portable use during travel, training sessions, and matches

The pump is not suitable for high-volume inflatables such as automotive tires, bicycle tires, air mattresses, or large pool toys, as it is specifically engineered for low-volume sports balls requiring precise lower pressure limits.

Key specifications

• Built-in 2600mAh rechargeable battery
• Maximum operating pressure up to 17 PSI
• Custom mode pressure range from 3 to 17 PSI
• Pressure measurement accuracy of ±0.3 PSI
• Pumping speed of 6.5 liters per minute
• Output and input power of 10 W
• USB-C charging interface
• Four operating modes including basketball, soccer, football, and custom

How to use

Charge the device fully using the USB-C port before first use. Select the desired operating mode corresponding to your sports equipment using the control interface, or input a custom pressure value between 3 and 17 PSI if necessary. Retrieve a brass needle from the integrated storage compartment on top of the device and attach it securely. Insert the needle into the valve of the ball, press the start button, and the pump will automatically inflate the item until it reaches the preset target pressure, stopping automatically once complete.

What to consider before purchase

• Verify that the maximum pressure limit of 17 PSI meets your specific equipment requirements
• Note that this model is designed primarily for sports balls rather than vehicle tires or large inflatables
• Consider the battery capacity if frequent, heavy-duty team use is planned away from a power source

For optimal battery longevity, recharge the device periodically when not in use for extended periods and store it in a dry environment protected from extreme temperatures.
