【4-Level Height Adjustment】By aligning the stoppers with the protruding parts, you can adjust the stand's angle in 4 levels. Ergonomically designed, the adjustable height allows you to work comfortably, effectively reducing neck and back fatigue and preventing slouching. The lightweight and thin design makes it a very convenient stand for working from home or in the office. 【Innovative New Technology & Instant Cooling】This is very useful for PC work in both winter and summer, and is the perfect tool for expensive PC users such as Macbooks. Although the main purpose is a laptop stand, you can save the trouble of buying another cooling pad! This is a cooling product that uses a plate-shaped semiconductor thermoelectric element - a Peltier element, so it is safe and cools down in just a few seconds, with excellent heat runaway prevention effects. Generally, it can cool the laptop chassis by 12°C to 18°C and the CPU temperature by about 12°C in about 5 minutes. It is a great item especially for thin and lightweight PCs such as the Macbook series and LAVIE N series, which are prone to overheating. 【High-Hardness Material - Excellent Stability】Adjusting the angle of the PC cooling pad/stand requires no force, and even children can use it without any problems. The triangular design, which maintains the most stability, shows no inclination at all and has excellent durability. By adopting CNC processing technology with excellent stability on a high-hardness alloy material, it can withstand about 20 kg of items, and there are silicone non-slip pads on the stand for stable use. The two black rubber hooks on the exterior are used when attaching a tablet, and can properly protect your valuable PC and tablet. 【Human-Centered Design, Active in Many Scenes】The role of cooling is mainly performed by the Peltier element, and the fan design also uses noise reduction technology applied to aircraft to reduce operating noise, so you don't have to worry about noise. The operating noise of the fan in the cooling device is only 18db, making it easy to work from home or in the office! Especially, the spring design allows you to adjust without blocking the heat exhaust holes of various PCs, eliminating the gap between the cooling element and the back of the PC, allowing for closer contact, reducing condensation and maximizing the cooling effect. Not limited to how to use a laptop stand, it is very easy to use even with various PCs and tablets from 12 to 17.8 inches.
