I recently had surgery that required an overnight stay. When they wheeled me in it was like a heat wave hit. No joke, it was 83 degrees in my room. I had purchased this fan to use at my son’s baseball games and thankfully, I brought it with me. I turned it on the lowest setting and set it in the tray. It provided enough cool airflow to make me comfortable for a full 9 HOURS straight. Then I just swapped out the battery. I was released before the second battery even went down a level. The lady in the bed next to me couldn’t hear it at all and the poor thing didn’t get a fan (although she asked) until the middle of the following morning. Best $35 I have ever spent.

was not expecting such powerful speed from a small fan. The battery last forever! you can literally turn it on for days. Moreover, it comes with a second battery. The fan can be used on any power bank. Great

Day 1: This is the is a SERIOUS fan for a small little compact portable fan. I will probably purchase a second to have but I will take this everywhere! I hate being hot... let alone even a little warm! It runs at three speeds by a momentary touch of the power button. I AM SATISFIED WITH THIS PURCHASE! The only down side is on high it makes a little noise but I'd rather have that then be hot!

Oh yes this is a goood fan. Bought for Disney World. This thing is powerful at all it’s settings. It will help cool you down in the FL heat for sure. I LOVE the 2 batteries. I haven’t switched batteries out yet but haven’t used more than intermittently. The batteries are supposed to last 10 hrs on the highest fan setting. This was very important after our trip in July where we bought 2 of Amazon’s best selling clip on battery operated fans that died aster a few hours! This is the most expensive little fan I’ve bought BUT well worth it! If there’s any cons it’s that the fan is quite small and the head doesn’t pivot around only tilts back. Which has not inhibited my use as of yet.

This is one of the best products I’ve ever purchased from Amazon. I’ve used this everyday this summer and it’s been a welcomed item on public transportation or at work when there’s no air conditioning. Several co-workers stated they would certainly buy one for themselves or a relative. It’s lightweight and I LOVE the additional battery that can be immediately switched when the other is at a low output. This is worth every penny. Also: I’ve placed this at the rear or on the side of my computer at medium speed to give my machine some cooling when I’m using it.

This is a MUST for outdoor activities in the South. I live in Louisiana where the weather is HUMID and HOT. I purchased this for my daughter to use for Homecoming Court, but it turned out to be cool that night. I used it at the following football game (of course Louisiana weather is unpredictable so the temperatures were much higher than the previous week). It was AWESOME. First time I didn't feel like I needed to take a shower after leaving a game. I'm hot natured and I now KEEP this fan in my vehicle at all times. My friend tried it and couldn't believe the power it had. She took it with her to the college football game (her daughter is on a dance team and performs at the games). ALL OF THE MOMS went crazy over it and wanted one. The second battery is a bonus! The price is great and I love that you can adjust the speed. I expected the battery to die on me I used it so much but still haven't had to switch them out.

I was so surprised when I got this little fan. It is so cool. Has two charge stations which comes in handy for charging multiple devices. Cannot tell you how much I love this fan. It BLOWS! It is really surprising how hard this fan blows. Just ordered my second fan.

This fan works well. The airflow is pretty strong. It is comfortable to hold. It charges properly in a reasonable time. I like that it comes with a second battery, although the battery life was good even on the highest of three speeds and I didn't need to switch batteries. It runs even when the charge cable is plugged in, which I like for when I use it at night next to my bed. But as a portable fan, it is very good. I went to a picnic when it was hot, humid, and sunny, and I was happy to carry it around and keep my head cool. The weight was not a problem for me. My only minor complaint would be that it is a little noisy on the high speed. That is only noticeable when I am using it at night.

Love this fan. I bought several from amazon to try various brands/designs and this is my favorite by far. I am a league bowler and go to the alley 3-4 times a week. It is extremely hot inside the building and this keeps me cool and prevents overheating. I can't speak to the longevity of this fan or the length of charge. But it has lasted the longest out of all the fans I purchased. I used it for approximately 2 hours last night and it still has plenty of charge left. It comes with a wired stand, but it is not needed as the fan folds and stands on its own. It has indicators that light up to let you know how much battery/charge is left (4 total). I like that it uses a power bank instead of batteries; the extra even came in handy when a friend needed to charge his phone (took half charge to get him to 80%). Pretty good product for the price. Very satisfied.

This is the BEST battery operated fan I ever bought from Amazon. #1 - It gives out the max power I need. It has 3 degrees of power/strength #2 - It is handy. So chic and very modern looking #3- Very durable. The material is just great. I dropped the battery pack, the fan several times now and they were just amazing #4- The batteries are quick to recharge and lasts for a longtime. I like the features of blue lights showing the the power of the batteries and if they needed recharging #5 Charging is very easy to do Great product! I would recommend this product anytime.
