OPOLAR Portable Battery Operated Handheld Personal Desk Fan with 5-20 Hours Working Time/5200mA Battery,3 Setting, Strong Wind,Foldable Design, for outdoor Activities

I cannot praise this fan highly enough. What a genius idea this is! Since it arrived I have used it every day and I don't know how I survived without it before. I bought it because I'm having constant hot flashes which I find unbearable and I was due to go on an international flight which would be unpleasant without some kind of fan. I didn't expect it to be as good as it is. The quality is amazing. It has incredible power and the battery lasts for days. I rarely have to recharge it. I keep it on for hours and battery indicator barely moves. I love that it folds for storage and the fact it stands on a table. I put it on the night stand while I watch TV or read or on the tray table on the airplane so I can have my hands free. I only need to put it on the lowest setting as the breeze it makes is substantial! The strongest setting is like being in a wind tunnel! I literally don't leave the house without it and it stops hot flashes in their tracks. The best money I ever spent. Highly recommended.Update Jan 2020: the fan is still going strong and still performing at a high level. I loved it so much I bought a second one. No regrets.

By far my favorite purchase on Amazon. Bought a few of these for whole family for trip to Disney World in Florida.June in Disney is stupid hot and humid with little wind. These saved us from the misery. The battery that comes with the fan unit is very substantial. Only one fan got down to one bar of power (4 bars is fully charged) the entire trip. Of course we ensured we charged them each night, but battery anxiety quickly went away after a couple times/days of using them and realizing we could use the fans on max output pretty much all day long.In fact my wife wound up using the battery unit to charge her phone quite often in addition to using the fan.Really enjoyed the fact it folds up into a tiny package. The weight is really light considering the battery output and how robust the fan is.Also gets major points for allowing the fan unit to disconnect from the supplied battery. The fan unit can be plugged directly to a micro USB for times you have a wall plugin. The fan unit plugs into the supplied batterybvia regular USB so you can use a huge variety of other power banks.If you have read this far, all else I can say is, if you want portable air that truly will affect your comfort, and will last a realistic timeframe, get it. I know I used one for over 4 hrs almost continuous on its highest setting and it still ran.

This fan is more powerful than an electrical desk fan. The only thing I don't like about it is to turn it off you have to cycle thru all 3 speeds ( push the button 3 times for low, medium and then high before it turns off. I always keep it on low because it would blow me away on medium or high. Right now I use it for a desk fan at work, but can't wait till summer to use it at outdoor concerts. It's awesome! It holds charge for a long time, but is slow to recharge, so I recharge it overnight which works perfectly. It's a bit slow when charging my iPhone, not as fast as my iFrog 5000 charger, so personally I don't use it for that. I just use my iFrog at work to charge my iPhone. Overall it's awesome, and I highly recommend it. I will definitely buy another one soon just for outdoor concerts. I love it very much!Hello again,I said I would definitely purchase another one and I did. I love this product. If you're buying a big fan or fan with a cord at work, don't bother. This little tiny fan is so much more powerful, it will blow you away. I would give it 7 stars but 5 is the limit. I love, love, love this little fan, and highly recommend it. You can take it anywhere and it's small enough to fit in a purse. I wouldn't be surprised if I end up buying a 3rd one. I just hope the manufacturer considers some girly colors i.e. cute pink, lime green, etc. Thank you manufacturer, I can't get enough of this fan. I simply love it!

I travel a lot for work and always hustling in and out of airports. This little fan is awesome to have on hand to help cool off a little and not look like a sweaty pig after running to catch a flight. It comes in handy for my hotel stays too keeping a slight breeze and white noise to help sleep. You can disconnect the fan from the power pack and run via USB power, most hotel alarm clocks have a USB connection on top so I plug it in, run it all night and still have a fresh battery pack the next day. I have ran the fan on battery pack all night, after 7 hours of sleep it still had well over 50% battery life. I bought a second one.... two is one and one is none.

Works very well. Wish there was a forth speed for even stronger air. Very light weight easy to store and carry around. Can be used with the battery power bar/power bank or with out it by just Simply plugging it to a computer or to an outlet with the cord. I love this product so far.

Battery life: excellent (I have it on overnight at slow speed and there's juice still left). Furthermore, I can connect the fan directly to another power bank.Portability: excellentI have bought several of these for my friends after they see me use it.Highly recommended.Attached photos on how to connect USB cables.

Tried it today at work for first time. Steal clip is a little flimsy. When using the clip the power/speed button is a little hard to access as it's on the bottom when laying on metal clip. The air flow for me was great-used on LOW for hot flashes and worked great! Bought one for home and one to stay at work.

This is my fourth Opolar handheld fan, but this ones my favourite. It has a longer battery life & indicator which is useful, my other ones just stop with no warning so you have to guess how long you’ve used it for (if you are taking it out with you as I do daily). Definitely worth the money.

I haven't used it much and the battery life is still going strong without even needing a recharge! The strength of the fan is great for the summer warmth. It's really worth the value for money. I'm impressed and will definitely recommend! Lots of the girlies in my mom's group wanted to know where I got it and I shared it with them!
