Replacement AC Adapter 20V 45W

This replacement AC adapter supplies 45 W through a USB Type‑C connector. It is intended for users who need a new power source for a compatible Toshiba laptop or other device that accepts 20 V 2.25 A input. The unit replaces the original PA5279U‑1ACA part.

Thermals and power draw

The adapter delivers up to 45 W across four fixed voltage rails of 5 V, 9 V, 15 V and 20 V. In normal use it runs at the rated 20 V 2.25 A output without exceeding its design limits. No active cooling is required and acoustic output is negligible.

Build fit and requirements

A USB‑C cable with a compatible device port is all that is needed to connect the adapter. It frees the user from a proprietary barrel connector and works with any system that negotiates the listed voltage steps. Buyers who need a higher wattage supply or a different output voltage should look elsewhere.

Questions about this item

How do I install this 20 V 2.25 A USB-C adapter, and which step is often missed?

Connect the AC plug to mains, then insert the USB-C connector into the laptop port; the step often missed is confirming the laptop negotiates 20 V rather than defaulting to 5 V or 15 V.

What maintenance or replacement will this 45 W adapter need later?

No scheduled maintenance is required; replace the unit if the cable frays, the USB-C plug loosens, or output voltage drifts from 20 V under load.

What limit appears first on this 45 W adapter during sustained use?

The 45 W power ceiling is reached first; drawing more than 2.25 A at 20 V will trigger overload protection or cause voltage to sag.
