SKU CH-4HCW-HEE7J

Replacement 19 V 2.1 A AC adapter with 10 ft cord and FCC, CE, RoHS certification

  • World-wide 100-240 V input works everywhere
  • 10 ft power cord gives flexible placement
  • Over-current, over-voltage and short-circuit protection keeps hardware safe
  • FCC, CE and RoHS certified for regulated quality
  • 19 V 2.1 A output matches original laptop requirements

Replacement AC Adapter for Asus Laptops

This 19 V 2.1 A power supply replaces the Asus ADP-40KD BB unit and delivers up to 3.42 A output. It accepts worldwide input voltage from 100 to 240 VAC at 50 or 60 Hz for international use. The adapter is built with new components and carries FCC, CE and RoHS certifications.

10 Ft Power Cord and Safety Protections

A total 10 Ft long cord gives flexible placement between the wall outlet and the laptop. Integrated safeguards include over current protection, over voltage protection, short circuit protection and total power protection. A smart chip adds overheating protection while isolation materials reduce interference.

Check Connector and Voltage Before Ordering

Verify that your laptop requires a 19 V input and uses the same barrel connector as the original ADP-40KD BB adapter. Confirm the device draws no more than 3.42 A so the supply can meet peak demand. Buyers needing a different voltage or connector type should select another model.

Questions about this item

Will the 10 ft power cord need replacing if the cable sheath cracks after extended use?

The cord is a single 10 ft assembly; if the sheath or connectors fail the whole cable must be swapped for a compatible 19 V 2.1 A unit.

Which protection circuit trips first when the adapter runs continuously at its 3.42 A peak rating?

Over-current protection activates before total-power or over-voltage limits, cutting output until the load drops below the 2.1 A continuous rating.

How hot does the brick get and does it make any fan noise during all-day operation?

The adapter has no fan and relies on passive cooling; surface temperature rises with load but stays within FCC, CE and RoHS limits for 100-240 VAC input.
