The USB Powered Desk Fan Aikoper hits you with a constant stream of cooling power without losing power or having a hiccup in its operation. There is a slight whirring sound when it\u2019s working, but it won\u2019t amount to anything. It\u2019s more background noise then it is anything else.

It\u2019s sleek and modern design will surely become the most eye-catching feature of wherever you decide to place it, and the whisper quiet operation means you can work or sleep without being disturbed.\r\n\r\nPerformance\/Power\r\nThe Aikoper USB Desk Fan contains the latest Aikoper technology, which is the twin turbo cyclone structure, to cut the airflow evenly and continuously. This allows the fan to constantly produce streams of cool air. It has two speeds, which is standard for a fan of this size, but it\u2019s not unheard of for fans to have more precise options. See the Vornado Pivot for a portable fan with three speed options.\r\nDurability\/Build\r\nAikoper Desk Fans feature a sleek and very modern design. Completely rejecting the traditional desktop fan design of competitors such as the Holmes Blizzard Fan, the Aikoper Desk Fan has a bionic shell sculpt with a painted black finish. There\u2019s no doubt it will be the most fashionable piece of equipment on your office desk. Weighing only 12 ounces, the fan is also easy to transport from room to room.\r\nNoise\/Sound Level\r\nThe Fan Aikoper USB Small Table Personal Electric Fan features whisper quiet operation. Despite the lack of dB-level measuring, the use of the term \u2018whisper quiet\u2019 leads us to believe it\u2019s somewhere around 40dB. By the company\u2019s own admission the fan does make a slight whirring sound which can be soothing background noise to some, but can also be annoying to others. Check out the Fancii USB Fan for something a bit more quiet.\r\nVersatility\/Modern Features\r\nThe Aikoper Desk Fan operation is as easy as pushing a button. Literally, a single button on the metal base is enough to turn the fan on or off. And since it\u2019s a USB fan, plugging it into your computer or power bank is enough to get it up and running. Because you won\u2019t be using AC or an electrical outlet to use the fan, you\u2019ll be saving on energy costs too.\r\nValue\r\nThe Aikoper Desk Fan has reduced vibration and wobble thanks to the rubber strips at the bottom of the fan. The fan comes with a 5V USB power supply, but it\u2019s not specified how long the cord is. Likewise, it only comes in one color: black. And while it\u2019s a painted black that can fit in with anything, we would have liked to see some bolder color operations to set the fan out from the rest of the pack.\r\nAikoper Desk Fan Wrap Up\r\nThe Aikoper Desk Fan may only contain two speeds, but the constant stream of cool air you\u2019ll get should more than make up for it. The painted black finish is strong, vibrant, and adds to the elegance of the design, and the one-button control system allows for easy operation even among the most technologically inexperienced among us.
