The Geek Aire Air Circulator Fan can run for 18 hours on a single charge, which takes only about 2.5-3 hours. An excellent trade-off. And while it may be a little heavy, it still weighs about the same as other best outdoor floor fans. Likewise, because of the rechargeable battery, the Geek Aire Fan is a best camping fan as well!\r\n\r\nWhy We Like It - Geek Aire Fan\r\nThe Geek Aire Fan eschews traditional AC power in favor of a 15,000mAH rechargeable lithium-ion battery with a power bank that can charge your personal electronic devices too. The all-metal construction adds durability and life, and the 180 degree tilt lets you point air to wherever it needs to go.\r\n\r\nPerformance\/Power\r\nGeek Aire Rechargeable Floor Fans features a 180 degree tilt feature so you can direct airflow simply to where it\u2019s needed most. It\u2019s very powerful and can blow air at 2500CFMs on the highest setting. This makes the Geek Aire Fan great not only for your home, but for outside, garages, and workshops too. And while the Geek Aire Fan does have variable speed settings, the exact levels aren\u2019t stated anywhere. If an oscillating tower fan with defined speeds is more of what you're looking for, check out the Pelonis Fan.\r\nDurability\/Build\r\nThe Geek Aire High Velocity Fan is built with a high quality, sturdy metal frame as well as metal fan blades. The all-metal construction gives you lasting durability and longevity so you can use the fan for years to come. The Geek Aire Fan weighs a little over 13 pounds, which isn\u2019t heavy but also not the lightest we\u2019ve seen. If you want something very light, check out the Ryobi Fan.\r\nNoise\/Sound Level\r\nThe Geek Aire Oscillating Fan states that noise level is dependent on speed, which makes complete sense. But along with not stating speed settings, they also don\u2019t state db levels. Turning to customer reviews we find that most customers are pleased with the very little noise the fan makes. Overall, it amounts to just some little white noise. If you use it outside a lot it may start to click, because it\u2019s a metal fan, but it\u2019s nothing some WD40 can\u2019t fix.\r\nVersatility\/Modern Features\r\nThe Geek Aire Variable Speed Floor Fan is powered by a 15000mAH rechargeable lithium-ion battery. By not having to plug the fan into an AC outlet to get it working, this feature will help you save on your energy bills. The battery takes only three hours to charge and can run for a maximum of 18 hours giving you a full day or two of cooling. And because it has a power bank, you can use the fan to charge your laptop and cellphone too! But you can also check out the B-Air FIRTANA if you\u2019d like a more traditional, non-tech fan.\r\nValue\r\nThe Geek Aire Portable Fan is missing one thing that will truly make it a high-tech fan, and that\u2019s a remote control. But then again, it\u2019s nice to see it keep some level of ruggedness. The fan black trim mixes very well with the yellow paint, which is probably why it was a Housewares Design Award finalist. Finally, the fan carries an IPX4 rating so it can survive rain, heavy or light, without much of an issue.\r\nGeek Aire Fan Wrap Up\r\nThe Geek Aire Fan blows powerful, high velocity air inside and outside. Because it\u2019s water resistant, you can also bring it camping or have it lounge by the pool with you, your family, and friends. It does miss a few high-tech things, like a remote control, but if you\u2019re planning to use it outside a remote control will just get lost amidst all the people and things, won\u2019t it?
