240W 20V 12A AC Adapter

This JPWEB adapter supplies 240 watts at 20 volts and 12 amps through a 6.0 x 3.7 mm barrel connector. It accepts 100-240 volt input at 50-60 hertz for worldwide use. The unit replaces the ADP-240EB B part number and includes a US power cord. Condition is new.

For ASUS ROG Strix and Zephyrus owners

It fits numerous ROG Strix SCAR 15, Strix G15, Strix SCAR 17, Zephyrus GX502, Zephyrus Duo 15 and Duo 15 SE models listed in the compatibility data. Buyers whose laptops require a different voltage, amperage or pin diameter should look at another adapter. Owners of non-ASUS notebooks cannot use this unit.

6.0 x 3.7 mm DC pin size

The critical specification is the 6.0 x 3.7 mm centre-positive barrel plug; if your device uses a different connector diameter or polarity this adapter will not connect. Verify the original charger’s output label reads 20V 12A before ordering. No other electrical or mechanical parameter overrides this physical fit requirement.

Questions about this item

The listing shows a single 240W model — is there any other capacity I should consider?

This adapter is only offered at 240W with a 20V 12A output. If your laptop requires a different wattage or voltage, this unit will not match the original specification.

What does the 240W rating mean when I plug it into my ROG laptop?

It delivers up to 20V at 12A, supplying the full power the listed ROG Strix and Zephyrus models expect for charging and high-load operation.

The barrel connector is 6.0x3.7mm — does that limit which ASUS models can use it?

Yes. Only laptops that accept a 6.0mm outer and 3.7mm inner diameter barrel at 20V 12A are compatible, such as the G533QS, GX502LXS, GX550LXS, G513IR, G513QR and G733QS series.
