What is the blower for?

It moves air without pressure, so it clears dust from a radiator or engine bay, inflates airbeds and paddle boards quickly, and can feed a charcoal fire. It is the function that separates a 3-in-1 from a 2-in-1.

How is a 6000mAh pack shared across three functions?

Starting, inflation and the blower draw from the same cells, so the display shows remaining capacity rather than a count per function. We measure jump starts, full tyre fills and blower run time separately on a sample.

Is the 14.8V system different from the 12V pumps?

It runs a higher-voltage pack, which is why the 21mm cylinder can be driven harder than the 19mm pumps. Starting output is still rated for 12V vehicle systems.

What is the packed weight?

Colour box 1150g, 12 units per 395x390x390mm carton at 14.5kg gross. The lower count per carton reflects the larger body.
