What this adapter powers

The Linksys MS15-050250-A1D delivers a regulated 5V 2.5A output from any AC supply between 100V and 240V at 50Hz or 60Hz. It is intended for devices that require exactly that voltage and current through a 5.5mm by 2.5mm barrel connector. The unit is new and carries the manufacturer's genuine part number.

Sustained-load behaviour

The adapter is designed to maintain its 5V 2.5A rating continuously rather than only in short bursts. Internal safeguards protect against incorrect voltage, short circuit and internal overheating during prolonged operation. Testing confirms no broken wires, loose particles or cracked housings that would degrade output stability over time.

Connector and voltage limits

The 5.5mm by 2.5mm barrel jack fixes the mechanical and electrical interface; only equipment specifying that exact connector and a 5V 2.5A draw should be attached. Input tolerance spans AC 100V to 240V at 50Hz or 60Hz, so the adapter cannot be used outside that mains range or with devices needing a different output voltage or polarity.

Questions about this item

Does the Linksys MS15-050250-A1D run hot or make noise when powering a device continuously?

The adapter has no fan and relies on passive cooling. Under normal load it stays warm but not excessively hot, and it operates silently.

What must I already own to use this 5.5x2.5mm connector with my hardware?

Your device needs a matching 5.5 mm outer diameter and 2.5 mm inner diameter DC jack that accepts 5 V at up to 2.5 A.

Will this 5 V 2.5 A unit safely replace an older 5 V 2 A supply on my legacy router?

Yes. The voltage matches at 5 V and the higher 2.5 A rating simply means it can deliver more current if the router demands it.
