Review on 🌬️ efluky 3 Speeds Mini Desk Fan with LED Light and 2200mAh Battery, Rechargeable Portable USB Fan Quiet for Home, Office, Travel, Camping, Outdoor, Indoor Use, 4.9-Inch, Black by Taj Tyagi

I ordered this on a whim. I was looking for a factory to move air past an electric heater. I actually accidentally ordered two and didn't fear a return for the price. My mother-in-law came to visit. She is an avid hiker and was blown away by the performance. She left with a second. A few notes: This runs on an 18650 cell. This is a common battery found in rechargeable flashlights. The device has a micro USB port for charging the battery, which can be charged with most Android phone chargers. When connected to the mains, the fan speed for charging the battery is significantly reduced. The running time at high speed is about six hours. Care should be taken not to completely discharge these batteries. This is a good deal if their use suits your needs.
