The OPOLAR battery operated desk fan comes with an excellent price to performance ratio. While looking to buy a USB rechargeable desk fan, the OPOLAR Clip Fan should be your go-to choice, as it is both the best stroller fan and the best camping fan on our list.\r\n\r\nWhy We Like It - OPOLAR Clip Fan\r\nThe OPOLAR Clip Fan is a very well designed 5 Inch rechargeable battery operated clip fan that lasts pretty long. And the clip\/body is large enough to use it as a handheld fan.\r\n\r\nPerformance\/Power\r\nAs the saying goes with pretty much every OPOLAR new fan, it\u2019s an extremely well-performing battery operated fan that provides strong airflow. You can select from three different speed settings, LOW, MED (Medium), and HIGH. And in each speed mode, the 5000mAh inbuilt battery lasts 20 hours, 10 hours, and 5 hours respectively. Basically, nothing (even a battery fan with more battery capacity) can beat the COMLIFE F170 Clip On Stroller Fan in terms of battery life.\r\nDurability\/Build\r\nEven though it looks a bit flimsy, it\u2019s pretty well made and durable. But the internal components are not that great. In fact, the motor will die on you after a while if you use this fan in a dusty environment. That\u2019s why you should open it up regularly and clean it from the inside. And the clip also is a bit flimsy. If you really need a flexible tripod clip fan, go for the Amacool Tripod Stroller Fan. And if you need a portable fan that can survive in a dusty environment, get the BLUBOON Clip On Fan.\r\nNoise\/Sound Level\r\nWith all we\u2019ve said against this fan, the noise it emits on all speed settings is pretty much negligible. And that is perfect for a baby stroller as it won\u2019t annoy your little one.\r\nVersatility\/Modern Features\r\nThis rechargeable clip fan is pretty excellent in terms of the modern features it provides. The strong clamp like clip of this USB desk fan holds it steady on pretty much every surface. Also, this OPOLAR battery operated fan has 360\u00b0 adjustability.\r\nValue\r\nFrom a positive perspective, the OPOLAR Clip Fan is a great buy for everyone who needs a battery fan. But you can get stroller fans with more features at lower prices too. So it\u2019s entirely up to you whether or not you\u2019d want to spend more on this fan.\r\nOPOLAR Clip Fan Wrap Up\r\nOn paper, the OPOLAR Clip Fan is pretty good. But when you start getting into the nitty-gritty details, this desk clip fan starts showing its weaknesses.
