Here are some common inflators and their recommended inflating pressure values:

Paddleboard (SUP)
General recommended pressure: 12-15 PSI
Competitive paddleboards: 15-20 PSI, or even higher, some high performance paddleboards may need to be inflated to 22 PSI.
Recreational paddle board: 12-15 PSI, this pressure range is sufficient to provide good stability and rigidity.
Inflatable kayak
General recommended pressure: 1.5-3 PSI
Due to differences in materials and design, inflatable kayaks have a lower recommended pressure, but can provide sufficient rigidity and buoyancy.
Air mattress
General recommended pressure: 0.5-1 PSI
Air mattresses are designed to provide a comfortable sleeping surface where the pressure does not need to be too high.
Inflatable boat
General recommended pressure: 2-4 PSI
The specific pressure depends on the type of vessel and the manufacturer's recommendations.
Inflatable life raft
General recommended pressure: 2-3 PSI
Life rafts need sufficient buoyancy and stability, and the pressure is usually set within this range.
Inflatable sofa and chairs
General recommended pressure: 0.5-1.5 PSI
These furniture inflatable products need to provide comfort and support, and the pressure does not need to be very high.

Why choose an electric sup pump

Save time and effort:

The electric pump can fill the slurry plate more quickly than the manual pump. This is very convenient for users who need to get into the water quickly.The use of electric inflators can avoid physical exertion, especially in high temperatures or bad weather, which is especially important.
Precise control:

Many electric inflators are equipped with a pressure gauge and an automatic stop function that allows a target pressure (usually PSI) to be set. When the set pressure is reached, the pump automatically stops charging to prevent overcharging or undercharging.
Portability and convenience:

Modern electric inflators are designed to be lightweight, easy to carry, and some can even be recharged for outdoor activities.
Portable electric inflators usually come with a variety of power options, such as on-board power interfaces and built-in batteries, to adapt to different use environments.
Wide applicability:

The electric air pump is usually equipped with a variety of adapters, which can be used for a variety of inflation equipment such as inflatable paddle board, inflatable kayak, inflatable mattress, etc., with diverse functions and high cost performance.
Consistency and reliability:

The electric pump provides consistent inflation speed and pressure output, ensuring consistent results each time. This is very important for people who need to use inflators frequently.
Reduce the risk of injury:

Manual inflation requires hard pushing and pulling, which may cause muscle fatigue or joint pain over time. The use of electric inflators can reduce these potential health risks.
In general, choosing an electric paddle pump can provide higher efficiency, convenience and inflation quality, especially for those who need to use inflation equipment frequently.
