This is a powerful 3 speed handheld fan. It's USB rechargeable, and has a LED battery power indicator. The battery is replaceable. I'm used to buying those 99 cent ones you find at the dollar stores which were better than nothing. After surviving two +90 F hot spells that continued for weeks in Europe and South America, I decided to include this fan in my travel kit. It is compact enough to carry around in a small backpack or purse, and it will be well worth it when the time comes to pause and cool off. It's a travel fan, and I'm sure it will serve me well. I'm looking forward to my next trip with it! Overall great buy and I highly recommend.
