It's written in the middle of "Port Tech" and "fan." I don't know the manufacturer. There are no instructions. The wind speed cannot be adjusted. There is a switch on the back of the fan. It doesn't oscillate, and the wind speed isn't strong, so it's for desk work. It can be angled upwards in two steps. The front cover can be removed and washed. Height: 19cm (max 23cm), width: 14cm, depth: 12cm. It runs on USB and AA batteries. The battery compartment is rusty. The sponge on the feet is a little dirty. Price includes shipping.
