Input Voltage and Connector Check

Verify that your laptop uses a 4-Pin DIN jack and requires 20 V DC at 11 A before ordering. The unit accepts worldwide mains input from 100 V to 240 V at 50 Hz or 60 Hz, so no separate voltage selector is needed.

Protection Features and Cord Length

Over-current, over-voltage, short-circuit and total-power protection circuits guard the adapter and the notebook during normal use. A 10 ft power cord provides flexible placement while the FCC, CE and RoHS certifications confirm compliance with safety standards.
