This little fan has become an extension of my hand. Stating the obvious, it's compact, rechargeable via USB which in my case means it's also solar because I have a solar charger for USB electronics. But to be honest I wasn't expecting much because I have a solar/USB fan that doesn't do much other than mentally making me feel a bit better when the power goes out. This fan is not that, I Keep it fully charged in case of power outage but I have it on my vanity and use it daily when applying make up and specially when putting on lashes. Did not expect the power of it and the fact that has 3 speeds blew my mind .
