I bought two of these fans. Unfortunately the batteries gave out within two weeks. One battery gave out and on the third charge. Now I’m stuck with two fans with one battery. Not able to buy new batteries….$84 down the drain……keep away from this brand with rechargeable batteries”
I've run this fan for 3 days now and it's great. Stuck it in a corner, on the tripod. Whisper quiet at lowest speed, with a slight hum. Have not had to swap or recharge the battery yet. I love this fan; I plan to buy more. (especially if Opolar makes a white version!)
Things to know:
1) The fan head does adjust up and down, but only slightly (maybe 10 degrees). If you want a fan that points straight up at the ceiling or straight down at the floor, this isn't it.
2) There is not a single 20,000mAh battery. Instead, there are two 10,000mAh batteries.
3) This is advertised as a desk fan - which it is. With the tripod, it's a floor fan too. At maximum height the fan head is about 41" off the ground. This will blow right at your head if you are sitting down. But not if you are standing. Which is why they call it a desk fan even if you put it on the tripod.
