The adapter delivers 180W continuously, matching the factory rating for GA401I, GA5021 and GA502D models. It will run those machines under full load while charging the battery. Systems that require more than 180W or a different voltage will not operate correctly with this unit.

Questions about this item

Will this 180 W adapter charge my older ASUS laptop that uses a 6.0 x 3.7 mm tip?

Yes — the adapter delivers 20 V at 9 A through a 6.0 x 3.7 mm centre-pin connector, matching the tip size listed for the supported ROG and TUF models.

How can I confirm the unit is delivering 20 V 9 A once plugged in?

The laptop’s battery indicator should show charging at full 180 W rate and the adapter’s LED (if present) will stay solid; no separate test equipment is required.

Does the package include both the power brick and a mains lead for UK sockets?

The box contains one AC adapter and one power cord; the cord ships with a UK plug when the UK variant is selected.
