Im not sure I can comment on the battery use as I run it plugged into my laptop USB port but it works very well for me. Its gives quite a strong breeze at the high setting and a gentle one at the low setting. I like the quietness and the ability to swivel it in any direction. Its very useful for the stuffy, hot library I have to sit in all day to do work with my laptop.

This fan does what it says! Stays charged for a long time. Haven’t timed how long it lasts with charge but so far it hasn’t let me down for the 2-3 hours I use it

This tiny powerhouse of a fan does exactly what its supposed to do. Its QUIET, very quiet. And its remarkable how much cooling air it produces. I clipped it to my headboard, and on LOW it cooled me completely. There was a surprise record setting heat day, and I turned it on medium instead of turning on the air conditioner. It kept me cool all night long. Hand in photo for the size comparison. This fan you can hold in your hand. Youll look at it and think... yeah, this thing isnt going to work. Ha! Wrong -- it can cool the immediate area down to meat-locker cool in a matter of moments. Did I say QUIET -- it doesnt hum or click, but a gentle, welcoming white noise that lulled me right to sleep.

It has three speeds. I honestly didn’t figure that out until the third day being without electrics. A tornado hit the area of my city hard and because my crappy insurance didn’t want to pay for my hotel stay which seems like bad faith to me I had to figure out dk ethnographic quick. I had a small battery pack for phones and small outlets also purchased off Amazon. This is 109% worth it. It kept me from suffocating in a 90F house, which the adjuster said was habitable after a tornado. Some folks are simply evil but I learned to improvise. This fan was necessary to not only keep my sanity but to keep me somewhat comfortable.

Got this fan for my husband who bowls multiple times a week and it helps when he’s waiting for his turn. This little fan works great! And can be charged in the car too!

Really impressed with the quality of this fan, especially for the price! There are 3 speed settings. The clip is sturdy. I use it for my stroller for my newborn and my toddler. I bought a second one I was so pleased! Rechargeable with cord included.

I love this fan! It has been great!! It cools nicely and hold charge well!

Buy it now! Bought this fan last minute before a camping trip and I can honestly say its one of the best purchases I made. The charge lasts a long time. Been using it consistently all weekend and its still going. Love the different speed settings and it clips onto anything and actually stays and also can stand on its own too. Small fan that packs a punch!

I bought one of these fans for my 4 month old to be comfortable on the boat. It’s so perfect. 3 fan speeds, the charge lasted 2.5 hours on full speed. The clip is perfect size for the boat window and infant carrier or stroller. I actually just bought a 2nd one just so we have an extra one if it dies.

The AC at work went out twice in 2 weeks!! I wish I had this but now I have 2! One for work and 1 for the house. Gulf coast is prone to heavy storms, hot weather, high humidity and power outages. Having a small fan that can be charged really is a necessity. 3 speeds have a good air flow and also pretty quiet.
