Review on 💨 Versatile 10000mAh Rechargeable Fan with Strong Airflow and Clip-on Design - Perfect for Office, Camping, and Gym! by Scott Mcgowan

This is a useful fan when you need long runtime and good performance but don't want to spend a lot of money for advanced features like big wings, fast charging and Type-C performance. + Clip-on fans are very handy for traveling and around the house for airflow while doing chores or speeding up cooling while cooking + Runs smoothly and performs pretty well The 37Wh battery is said to give 9 hours of battery life worries. The manufacturer claims only 7.5 hours of battery life at maximum performance, and my device was able to achieve that without any problems + I like that it has mode indicator lights visible behind the fan. The red light indicates it's on, and the blue lights indicate the mode: low, medium, high, variable. It only shines 1 blue light at a time, so if you forget the mode you're set and instinctively don't know the distance, you won't necessarily know which mode is on, but you can quickly find out the setting by cranking the fan. modes. + The clip has decent padding to prevent damage. The spring has good strength, but the lever on the handle is enough to open the clamp with moderate force. As long as the structure you install it on has adequate friction and geometry, it can stick to a shaking surface while the fan is running without losing grip. - 8" refers to the height of the entire fan assembly, the actual diameter of the circle section is less than 5". Smaller blades = less efficiency and tighter spread. There is no battery level indicator. You can expect a 10,000mAh device has about 37 Wh of power, since 3.7 V is typically the standard voltage for small portable devices. Many portable fans with similarly sized batteries can achieve charge rates of 10 W and even 15 W, since lithium batteries are generally expected to work with the same power as their rated power (37Wh = 37W power, 1C), however, this fan uses Micro USB charging at very low speed, the charging port is rated at 5V 1A (5W) and the maximum charging rate is 7W at 0% and gradually decreases as the battery fills up.A full charge from empty takes over 7 hours, so you need to allocate a USB port to let it air he works.
