Q: If you already have the DeWalt batteries his is a great addition. This fan is so convenient to use that I end up using it all the time. It moves an impressive amount of air while at the same time is quiet. A 6Ah battery runs for over 10 hours on high.

A: positive
****
Q: Perfect as a personal item. NOT considered a carry on and you won't be charged for it! Wonderful when flying certain carriers that charge for everything!

A: positive
****
Q: I wish I could give less than one star. Twice I was purchased this product from this seller & twice it has crapped out shortly after the return window closed. I would say more but I'm down to less than 20% on my battery so I have to find my travel charger

A:
negative
