Question about Stx Electric SUP Pump incl. battery

I've never tried this, but if you read the description of the pump at various suppliers, they always talk about two to three SUPs. Suppliers, there is always talk of two to three SUPs. Overheating is, I assume, not a problem because the pump is extremely "relaxed" in terms of noise and vibration. It's comparable to a 12-cylinder engine at 100km/h that runs at just above idle speed and neither ages nor burns any significant amount of fuel.
This is not a scientific answer, but at least it is an assessment.
