mimi fan

Mini fans are typically powered in one of three ways: USB power, plug-in (AC) electric power, or battery power. Many models list USB or plug-in power as their primary source, while some are battery-powered.

Mini fans commonly offer between 1 and 6 speed settings. Many models provide a 3-speed control, some rechargeable models offer up to 6 speeds, and a few are single-speed.

Reported rechargeable capacities include around 2000 mAh and 4000 mAh. Stated run times vary by capacity and fan speed—for example, a 4000 mAh model may list about 4–18 hours depending on speed, while a 2000 mAh model may list roughly 12 hours (low), 10 hours (medium), and 8 hours (high). Some models list other runtimes (for example, up to about 6 hours).

Mini fans range from very compact units (around 3.74 inches tall) to larger tabletop models (about 12.9 inches tall). Weights in listings span roughly 0.35 pounds up to about 2.73 pounds.

Several rechargeable mini fans list a full recharge time of about 1.5 hours. Recharge times can vary by model and battery capacity, so listed charge times should be checked for each product.
