Makita 18V Cordless Industrial Fan

Makita 18V / 14.4V Battery Compatible Industrial Fan CF301D

This fan can be used with AC100V power.

I've owned it for about 2 years and used it on job sites and at home.
As it is a fan, it can be quite noisy.
However, if you are using it outdoors or in a noisy environment, the sound may not be an issue.

I don't think it's suitable for use while sleeping.

Thank you.
