1. The power adapter outputs 5V/1A 15V/2.58A. Compared with the rated voltage and current of general chargers, we innovate and optimize the output method to ensure that the power supply has good stability and high accuracy, and avoid computer flickering, battery charging time, etc. Transmission is more stable, safer and faster.2. PC+ABS material, strong heat resistance, high temperature resistance, flame retardant and fireproof, high temperature burning test does not deform, realizing real fire prevention and anti-cracking, meeting the V0 fire rating standard3. Encrypted copper core, accelerating charging, high-quality wire with thickened copper core, tinned copper core, energy-saving transmission power, high oxidation and corrosion resistance, ensuring the service life of the wire4. Applicable computer models: for Microsoft SURFACE BOOK 3, SURFACE BOOK 2, SURFACE BOOK, SURFACE LAPTOP 3, SURFACE LAPTOP, SURFACE LAPTOP, SURFACE PRO X, SURFACE PRO 7, SURFACE PRO 6, SURFACE PRO (fifth generation), etc. Wait.5.
