If the pump still does not turn on after following these steps, please contact our customer support team for further assistance. They will be able to provide additional troubleshooting tips or arrange for a replacement if necessary.
The Smart Pump Pro offers two inflation modes: a faster mode that produces more noise and a slightly slower mode that is quieter.
It's important to note that all battery-powered pumps generate some level of noise. However, rest assured that the noise level of the Smart Pump Pro is around 75 decibels, which is designed to minimize disturbance while efficiently inflating your items.
When used on a plane, the noise from any pump is usually muffled to some extent by the sound of the plane's engines. It's worth mentioning that with the Smart Pump Pro's faster inflation speed, the noise duration is reduced, resulting in a shorter overall noise exposure.
I have attached a video for your reference on how to use the fast and slow mode.
