Compatible FSP 48V 180W Adapter

This new AC adapter replaces the FSP180-AFAN1 unit rated at 48 volts and 3.75 amps. It delivers 180 watts through a four-pin connector with the v+ Left orientation. The unit is built to meet the original equipment specifications for compatible laptops.

Fits FSP part number FSP180-AFAN1

The adapter suits owners who have verified that their original charger carries the exact FSP180-AFAN1 part number and the 48V 3.75A rating. Buyers who cannot confirm that part number or who need a different voltage, amperage or pin layout should look at other options.

Four-pin v+ Left connector

The single specification that decides fit is the four-pin connector with v+ Left polarity matching the FSP180-AFAN1 design. Only laptops wired for this exact pin arrangement will work with this adapter.

Questions about this item

How do I install the 4-pin FSP180-AFAN1 adapter, and what is the common mistake?

Align the 4-pin connector with the laptop's DC-in jack so the v+ Left orientation matches, then push straight in until it clicks; the step people get wrong is forcing it in rotated 180 degrees, which bends the inner pins.

What maintenance or replacement will this 180W adapter need later?

The 12-month warranty covers defects; after that the 48V 3.75A brick itself may need replacement if the cable frays or the barrel connector loosens from repeated insertion cycles.

What limit appears first when the adapter runs at full 180W continuously?

Sustained 180W output causes the internal components to reach their thermal ceiling first, triggering protection shutdown until the unit cools below the trip point.
