The SUNCA SF-399A portable fan comes with a rechargeable battery. However, this model has a durable build even though it is still made out of plastic.
This model also has 3 adjustable speeds that can be selected with a push of a button. On a fully charged battery, you can get anywhere from 6 to 10 hours of use depending on the speed mode you choose. One additional advantage this fan has is a “misting” feature with 3 misting speeds that is so convenient on those hot summer days.
