Description
It looks modest. It blows hard.
The Underdog Blast is a 120mm metal-ducted handheld jet fan that wears its power
quietly. No flashy bodywork, no exaggerated claims — just a pair of precision
metal ducted impellers, a brushless drivetrain, and a theoretical thrust of up to
20 kg waiting behind the honeycomb guard.
If you know, you know.

WHAT'S INSIDE
────────────────────────────────────
• Twin 120mm metal ducted impellers
All-metal housings, balanced rotors, built for sustained high-RPM abuse.

trigger. Respect the output.
• 18 Ah smart battery, included
High-density smart pack, balanced cells, built-in protection, ready to run
out of the box.
• Bluetooth smart control
Pair with your phone for power adjustment, runtime monitoring and switch
control — no fiddly dials on the grip.
• Gun-style grip, 3D-printed composite body
Ergonomic, well-balanced, sits naturally in your hand under full thrust.

A WORD ON SAFETY
────────────────────────────────────
This fan does not mess around. Because the thrust is genuinely that strong,
we strongly recommend running it with the included blue protective guard fitted.
Keep fingers, loose clothing and long hair clear of the impeller. Never point
it at people, animals or fragile objects. Wear eye protection.
