Review on 🔋 KOONIE 10000mAh Portable Fan: Rechargeable Clip-On USB Fan with Strong Airflow - Ideal for Office, Travel, Camping, and Gym by Jim Ball

Bought for my husband who loves air circulation even when the house is cold. I always complain about fan noise when trying to sleep so this was a great solution for us. Now he takes it everywhere - on the patio, on the boat, on a picnic, etc. Needless to say, he loves this fan. One charge and it will last all night, I think it's the longest he's tried to use it. It won't cool the entire room in my opinion, but if you use it as a personal fan or in a small area it will help!
