The featherweight end of the catalogue: bodies around half a pound built on 4,000mAh and 5,000mAh cells, with turbo motors reaching 11,000–13,000RPM and runtimes of 20 to 25 hours on low. They keep the grown-up hardware — opposed steel clamps, bottom air intake, silicone armour, USB output — in a shell small enough to clip to a shirt collar or vanish into a jacket pocket.

They are tuned differently rather than cut down. Airflow reaches 19.69ft/s with an 8.2-foot supply distance, which is real cooling, and the five- or four-speed control scheme is carried over unchanged. What you give up is total battery capacity, not build quality.
Charge time. A 4,000mAh cell refills in two to three hours and a 5,000mAh cell is not far behind, so these recover over a lunch break while the big packs need most of a night. On thin summer fabric their low weight also keeps the clamp geometry working where a heavier fan would flop.
They carry a 5V-2A USB output with a dust plug over the port, so an emergency top-up is possible. Treat it as a genuine emergency feature — the same small cell has to run the fan.
