1. The power adapter outputs 5V/1A 15V/4A. Compared with the rated voltage and current of general chargers, we and optimize the output to that the power supply has good stability and high accuracy, and avoids computer flickering, battery charging time and other phenomena. More stable, 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 standard 3. 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 wire 4. Applicable computer models: For 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. Magnetic interface, charging faster and , stable voltage and current, faster conversion efficiency, lower heat generation Output voltage: 5V/1A 15V/4A Input voltage range: 100-240V Applicable form of charger: direct charge Applicable products: laptop Scope of application: for Output current: 4A Power: 65W Charging interface: magnetic interface Line length: 2.
