  • World-wide 100-240V input works anywhere
  • 10 ft total cord length gives flexible placement
  • Over-current, over-voltage and short-circuit protection keeps hardware safe
  • FCC, CE and RoHS certified for regulated quality

Compatible Power Adapter for Dell Precision 7550

This WAWEIS AC/DC adapter replaces the original Dell Precision 7550 N7MWW charger. It delivers worldwide input voltage from 100 to 240 VAC at 50 or 60 Hz. The unit includes a 10 ft power cord for flexible desk placement. Safety certifications cover FCC, CE and RoHS standards.

Practical Limits of the Barrel Connector Interface

The barrel connector fits only the Dell Precision 7550 N7MWW charging port. It cannot supply power to laptops that require USB-C Power Delivery or a different barrel size. The fixed output voltage and current match the original specification exactly. No fast-charge negotiation or multi-voltage switching is supported.

Replaces Lost or Damaged OEM Charger

This adapter replaces a lost, frayed or failed original charger for the Precision 7550. The jump is worth it when the original unit shows exposed wires, intermittent charging or no power LED. Built-in over-current, over-voltage, short-circuit and thermal protections guard the laptop during daily use.
