How does the Emanjor 90W adapter protect my laptop?

The adapter integrates several electrical safeguards and adheres to common international safety standards to protect both the power supply and the connected laptop. These protections help prevent damage from common power issues.

• Over-current protection to stop excessive current draw that can overheat components.
• Over-voltage protection to prevent surges from reaching the laptop’s internal circuits.
• Short-circuit protection to cut output if a fault is detected, reducing risk of damage.
• Manufacturing and certification alignment with CE, FCC and RoHS guidance for safer operation.
