This is the their one I got for a small space to move air around, dry delicate things and run off a usb power bank when I need it too. The battery lasts the build quality is excellent and it's very reasonably priced.
I am impressed with it, I highly recommend this to anyone looking for a portable fan, that's not only effective but good quality.
It is ideal for all, babies upto adults. There's endless possibilities for this and it's awesome!!
