Dell 2MWVW 90 W AC Adapter — Who It Serves

This 90-watt AC adapter delivers 19.5 volts at 4.62 amps through a 4.5-millimetre barrel tip. It is built for Dell laptops that require the original 2MWVW or 02MWVW part number and the matching voltage and current ratings. Buyers needing a higher-wattage supply or a different connector size should look elsewhere.

Sustained Load Behaviour

The Chicony Power Technology HA90PM190 design is rated for continuous 90-watt output, so it maintains stable voltage during extended charging or high-performance workloads without dropping to a lower burst rating. Thermal protection engages if internal temperatures exceed safe limits, allowing the adapter to throttle rather than shut down abruptly.

Compatibility Check Before Ordering

Verify that your laptop lists the 2MWVW or 02MWVW part number and accepts a 4.5-millimetre barrel connector at 19.5 volts and 4.62 amps. Confirm the original adapter’s label matches these exact specifications; a different tip diameter or voltage will prevent proper operation.
