The Laptop Cooling Pad uses a macromolecular compound for the absorbtion of excess heat. This macromolecular compound remains in granular or crystal format up to temperatures of 25℃ Place a laptop computer directly on this pad, the pad will absorb large amounts of heat from the laptop’s base, the granules or crystals will slowly absorb heat and will change their molecular appearance, forming a viscous gel, this will continually absorb heat and allow any item in contact to dissipate it’s own heat output Revolutionary fanless design for absolute silence No extra external power required, get rid of astriction from the wire Exclusive heat-shift technology for ultimate laptop cooling Ultra light weight for easy transportation and carrying(only 640 grams) Long duration of absorbing heat(3~8 hours) Can be folded at both solid and liquid state Soft and durable material designed for maximum portability Suitable for all types of laptop computers Can be used as a cooling cushion Keep your laptop working at normal temperature to increase service life
