JISULIFE’s handheld fan solves two summer problems at once. It’s a powerful personal cooler that also serves as a reliable 4500 mAh power bank. This dual-purpose design means one less cable and dead device to worry about when you’re out for the day.

The updated blade design pushes 30% more air than the previous model. You feel the difference immediately—it’s a steady, focused breeze, not a weak puff. On its lowest setting, the fan runs for up to 37 hours, easily lasting through a weekend trip or multiple commutes on a single charge. The three speed settings give you control from a gentle background hum to a robust cooling wind.

It folds compactly for a bag or pocket, and the matte black finish feels sturdy, not cheap. While the airflow is strong for its size, it’s still a personal fan, not a desk fan replacement. The built-in battery is a genuine utility, capable of giving a smartphone a full charge. It’s a practical piece of gear that earns its keep.
