OPOLAR Cordless Rechargeable Oscillating Tower Fan, 5000mAh Battery Operated Desk Fan, with 3-12H Working Hours, Quick Charge, for Travel, Camping and Outdoor Activities

Bought this fan for a music festival where we were camping in the heat. I have two other battery operated fans from previous years and was hoping to supplement with this one. The battery died after about 45 minutes of use. My other fans lasted the entire weekend. This fan would work well if you can keep it plugged in during use. Not worthwhile for an outdoor setting or place where you don't have power.

It's so frustrating to go with what people say in a review and to find out that almost everyone that put a review no in fact everyone that put a review lied the fan is weak and has no wind power whatsoever it's a waste of money and space definitely not worth almost $50 wouldn't even pay $20 please be honest it's a horrible product don't waste your time shame on everyone for lying.

Absolutely hands-down the best USB charged portable dual tower fan that’s small compact powerful with oscillating option charge indicator and can use both fans or shut one off to conserve power. Each fan can be adjusted up down.It’s amazing how compact this Van Ness and how powerful that is for its size and what’s best is during hurricane times and loss of electricity I’m able to charge it through USB port and last close to six hours on moderate power for hours on full power 10 to 12 hours on low powerAbsolutely recommend this purchase for summer time and in home useI bought 2 last year and another 2 this yearGreat qualityQuiet

I really enjoy the size of this fan! It can be placed on a desk and not feel like it's taking up too much real estate. The duel fan setup is a smart design, and I feel very comfortable even with the low setting after a few minutes. If you set it higher it feels as powerful as an A/C and can be used to cool of a small sized room. It has a built in battery, and the fact that you can charge via USB is very convenient. Recommended if you work in a warm/stuff office, it will really make a big difference in your overall comfort.

My fan lasted 2 years and still going! I love it this got me through not having a/c when I couldn't afford one! My husband has one too! I don't know what the negative ratings are about maybe got lemons but I have no problems with them both! I travel with them from my 560 sq ft apartment to my sisters no problem! I'm constantly going over to see my mother there and I'm always warm there! My husband has his on ALL day and it still works and his is just making it over a year this Feb. and he goes through fans like crazy this is the only one to make it this long! LOL He drops it from it being on this tv tray we have because we had such a short wire it came with. I had to buy a longer one. He takes it from bedroom to our tv room daily! So if it can withstand my husbands abuse it can stand anything! LOL I think it just matters if you get a good one or if it's how you take care of it, all depends on the maker or the person I guess!

I bought these specifically for when our power goes out. They are good size and weight. They charge with a USB cord. They put out good fan power and can rotate and adjust the position of each fan. You can alternate between fans and have them both running at the same time. I have them charged always in case of a power outage so I can rely on them to get me through the night. Worst case scenario I charge them back up in my car, which is another plus of them charging by USB. My only complaint is I wish the battery life was a little better. No matter what speed you have this fan on, if you wake up in the morning the fan be have run out of battery. I have relied on these several times and they do help me get through the night without my main fan in my bedroom. Nice to have so I suggest at least 2 or 3.

I love that you can adjust the fan to direct air both front and back while oscillating. Battery life is okay but should have bought the 10,000mAh battery for longer run time. Nice fan but a little pricey...

Product stopped working super fast. I got my unit replaced only to have the new one fail within the first month. Battery doesn’t hold a charge and the bottom fan was the first to break both times.Was really a fan of the design and the size, but when it comes to longevity this unit falls short. :(Also: contacted Opolar customer service with at least one email a week and have gotten 0 relies. I’m writing this review about a month later, but I’m still very unhappy.
