Although marketed for strollers, its compact 2000mAh battery and 3-speed options make it suitable for treadmill workouts where space is tight and you want a low-profile fan.

Caution: battery life varies by speed; top speed will reduce runtime more quickly.

Best for long treadmill sessions and outdoor use where sustained cooling matters. The 40000mAh battery delivers a claimed 20–150 hours of runtime depending on mode, with a 2-in-1 design that converts into a desk fan.

Limitation: heavier unit and higher cost, but extended operation justifies the trade-off for frequent outdoor workouts.
