WAWEIS 180W 4-Prong AC Adapter for Toshiba Qosmio X775-3DV78

SKU CH-SFDG-T79TN

180 W replacement AC adapter with a 10 ft power cord, worldwide 100-240 V input, and FCC, CE and RoHS certification for the Toshiba Qosmio X775-3DV78

  • World-wide 100-240V input for travel flexibility
  • 180W output with 4-prong connector matches original spec
  • 10 ft total cord length gives extra reach
  • FCC, CE and RoHS certified for safety compliance
  • Over-voltage, over-current, short-circuit and overload protection built in

What this adapter replaces

The WAWEIS 180W unit replaces the original Toshiba PA3546U-1ACA, PA3546E-1AC3 and PA3673U-1AC3 chargers for the Qosmio X775-3DV78 notebook. It delivers the same 180 W output through a four-prong connector so the laptop charges and runs exactly as designed.

Cable length and protection features

A 10 ft total power cord lets you reach distant sockets without an extension lead. Built-in safeguards include over-current, over-voltage, short-circuit and total-power protection plus overload, over-charge, over-discharge and overheating guards managed by a smart chip. The adapter carries FCC, CE and RoHS certification.

Check your laptop model and connector

Confirm the machine is a Toshiba Qosmio X775-3DV78 and that the original charger uses a four-prong barrel tip. The adapter accepts 100-240 VAC at 50/60 Hz for worldwide use, but verify the tip matches before ordering.

Questions about this item

Will the 4-prong connector or the 10 ft cord need replacing first?

The 4-prong connector is built into the adapter body, so it only fails if the unit itself fails. The detachable 10 ft cord can be swapped separately if it frays or the plug bends.

Which protection circuit trips first during a long gaming session?

Over-current protection is the first limit reached under sustained heavy load; the adapter will shut down before overheating protection activates.

How hot and loud does the brick get when it runs all day?

The adapter has no fan, so it is silent. The casing becomes warm to the touch but stays within safe limits thanks to over-heating and short-circuit safeguards.
