WAWEIS 150W AC Adapter 19.5V 7.7A PA-15 D2746 laptop battery

Replacement 150W AC Adapter

This WAWEIS power supply replaces a Dell PA-15 family adapter rated at 19.5V and 7.7A. It delivers 150W output through a 10 ft cord and carries FCC, CE and RoHS certification. The unit is brand new and built with 100% new components.

Compatibility check before ordering

Verify that your laptop requires a 19.5V 7.7A barrel connector and that the original part number matches PA-15 or D2746. Confirm the device draws no more than 150W and that the mains voltage in your region falls within the 100-240VAC 50/60Hz range. The adapter is not suitable for devices needing a different voltage, amperage or connector type.

Build integration and protections

The adapter plugs directly into a wall outlet and supplies regulated DC power to the laptop, freeing the internal battery from charging duties while the system runs. Integrated safeguards include over-current, over-voltage, short-circuit, overload, over-charge, over-discharge and overheating protection managed by a smart chip. High-quality wires and anti-interference isolation materials maintain stable delivery during operation.
