Universal AC adapter for Phihong PSM03A-100-R

This WAWEIS AC adapter replaces the Phihong PSM03A-100-R switching power supply for compatible laptops. It accepts a worldwide input range of 100-240V AC at 50/60Hz, so it works across different mains standards without a separate voltage selector. The unit ships new and includes a 6.5 ft power cord for flexible desk placement.

Continuous operation with multi-layer protection

The adapter delivers steady output under sustained load thanks to over-current, over-voltage, short-circuit and total-power protection circuits. An internal smart chip adds overheat protection while isolation materials suppress interference during long charging sessions. All components are 100% new and tested to FCC, CE and RoHS standards for reliable daily use.

Limits of the fixed-output barrel interface

The barrel connector and voltage are fixed to match the Phihong PSM03A-100-R specification, so the adapter cannot serve devices that require a different tip size, polarity or output voltage. It also lacks USB-PD or programmable-voltage negotiation, meaning it cannot charge modern laptops that demand variable profiles over USB-C. Buyers needing multi-voltage or USB-C charging should choose a different power supply.

Questions about this item

How much heat or noise does the PSM03A-100-R adapter produce when running all day?

The unit has no fan and uses passive cooling, so it runs silently; normal warmth is expected during continuous use.

What must I already own for this WAWEIS adapter to work with my laptop?

You need a laptop that uses the Phihong PSM03A-100-R tip and voltage; the package supplies only the adapter and 6.5 ft cord.

Will this charger work alongside an older Phihong PSM03A-100 unit I keep as a spare?

Yes, both share the 100-240 VAC 50/60 Hz input and identical output specification, so they are interchangeable.
