I have this base (used) with 6 fans and blue lighting for cooling the laptop. The fans push air to the laptop and the cooling is good. There are two USB inputs to power the fans, and the cable is USB to USB. It has a control for the fan speed and lighting (with a dial). It comes with a phone stand and is a laptop stand as shown in the pictures. It is suitable for laptops up to 15.6 inches and even 16 inches. The reason for selling is that I don't need it, and it's 100% working. Purchase price was 70 SAR, and I used it lightly. Selling price is 35 SAR.
