Missing fan control panel
The battery only lasts two hours, it's light, it barely has a breeze of air at 10 cm, it has an LED light that doesn't turn off, etc. Don't buy it.
This fan wasn't up to expectations. The fan speed at max power was lower than much smaller and cheaper desktop usb fans that were 1/4 of the price. The fan wasn't really balanced when extended to full height because the base was really light. The fan would also fold over if not set up straight. Battery life was pretty poor and about half of the stated 5 hours. Not recommended at this price
The height is adjustable as described. 4 speed options.
However, it's very weak - not so good if it's not very close to you.. and it stopped working after about 2 weeks of use.
The wind is much weaker than the one bought two years ago. Only the remote control function is good.
