What to know before buying

Listing details to confirm

Listing details are contradictory or inconsistent: the title says 180W and 150W, while the detailed description specifies 180W maximum and says it is compatible with 150W or 120W chargers. The table also gives 240 Volts input and an output voltage of 240, while other details state AC 100-240V input and 20V output. The listing names USB 2.0 Micro B and USB Type C as wired charging connectors despite describing a DC barrel charger. It also mixes US power-cord wording with a Type I Australian plug claim. Confirm the required wattage, voltage, barrel size and supplied plug against your original charger and laptop. The listing specifically says this is not a replacement for a 230W, 19.5V, 11.8A charger.

Who is it for?

A good fit for

Owners of a listed ASUS laptop whose original adapter calls for a 6.0 × 3.7 mm barrel plug and matching 180W-class power specifications.
Buyers seeking a corded laptop adapter with a Type I three-pin Australian plug claim.

Less suited to

Laptops requiring a different connector size or a 230W, 19.5V, 11.8A charger.
Buyers unable to verify their exact laptop model and original charger specifications against the listing.

Aggregate ratings are limited and sharply divided, with five-star and one-star ratings represented and no middle-star ratings shown. This provides little detail about fit or operation. For a charger where connector size and required power are critical, verify those specifications directly rather than treating the ratings as evidence of compatibility.

Frequently asked questions

Which connector size does the listing specify?

It specifies a 6.0 × 3.7 mm barrel connector and says the charger is only compatible with ASUS laptops using that size. Check your original plug before ordering.

Is this a 150W or 180W charger?

The title mentions both 180W and 150W. The detailed description calls it 180W maximum and says it is also compatible with 150W or 120W, so match the laptop’s required input rather than relying on the title alone.

Can it replace a 230W ASUS charger?

The listing says it cannot replace a 230W, 19.5V, 11.8A charger.

Does the listing confirm an Australian plug?

It lists a Type I three-pin Australian plug, but the package description also refers to a US power cord. Confirm the supplied cord for the selected listing.
