Dskeuzeew Rechargeable Paddle Board Pump – 9000mAh Electric

Why does the sound become louder during inflation?

As the internal pressure of the inflated object increases, the sup pump automatically switches to high pressure mode, allowing more air to enter the object and causing the sound to become louder.

Why can’t the pressure value continue to rise when the pump reaches 1.0PSI?

When entering the critical value of 1.0PSI, the pump triggers a transition from low pressure to high pressure, creating a 30-50s delay as the value goes from 1.0 to 1.1PSI. Please wait patiently until the transition is complete.

Why can’t paddle board pump reach the preset pressure?

Please check the airtightness of the hose connection and the paddleboard, and ensure that there are no leaks in the hose or the paddleboard. If everything seems fine, please reach out to us for assistance.

How should I use the USB and car DC cables that come with SUP air pump?

The sup pump’s battery can only be charged through the C port. The car DC cable is for direct power only and cannot charge the battery. Please refer to the included charging instructions for more details.

Why did rechargeable air pump suddenly stop working during operation?

In summer, the paddle board pump may overheat due to the high temperature and compression of air inside the cylinder. To avoid this, give the pump 15 minutes to cool down after using it for half an hour.
