20 PSI rechargeable paddle board pump

The Tonsim 2040C is a rechargeable electric pump built for stand-up paddle boards and other inflatables. It delivers a maximum pressure of 20 PSI and offers both inflation and deflation functions. A 10.6 ft board reaches full pressure in about 4 minutes. The unit includes a 15000mAh lithium-ion battery and a 12V DC car connector for flexible power options.

Dual-stage airflow with auto shut-off

The pump operates in two airflow modes: 350 L/min for rapid inflation and 70 L/min for high-pressure topping off. An LCD screen shows real-time pressure and allows manual targets up to 120 PSI. The motor stops automatically when the set pressure is reached, preventing over-inflation. Four preset modes simplify operation for different inflatable types.

15000mAh battery runtime

The integrated 15000mAh battery provides up to 36 minutes of continuous use, enough to inflate roughly seven 10.6 ft paddle boards on a single charge. For longer sessions the 12V DC car adapter supplies power directly from a vehicle. Seven interchangeable nozzles cover kayaks, air mattresses, pool toys and other common inflatables.

Questions about this item

Should I pick the 350 L/min high-speed mode or the 70 L/min high-pressure mode for my paddle board?

Use the 350 L/min mode for rapid bulk inflation, then the pump switches to 70 L/min to reach the final 20 PSI target precisely.

How long does the 15000 mAh battery last when inflating a 10.6 ft board to 20 PSI?

A full charge runs about 36 minutes and can inflate roughly seven 10.6 ft boards to 20 PSI before needing a recharge.

What does the 120 PSI manual setting on the LCD actually limit?

The pump's maximum working pressure is 20 PSI; the 120 PSI figure is the upper limit of the digital gauge display, not an operating pressure.
