Now this is just one darn cool gadget. Whats in my opinion is you its portable and you don’t need to mess with the power cord. This can be a pain if your not near a socket to use. This is great for outdoors if its just humid outside. It does have a power cord to use if you want too. It gets about 8 hours of time on a full charge. It isn’t as cheap as a normal fan and cost about $60.00. However think of all the energy cost you will save on in the long run.
