Questions about this item

What does the 240W rating mean when the adapter is connected to a Zephyrus G14 (2023) GA402XU?

The adapter can deliver up to 240 watts at 20 volts and 12 amps, so the laptop draws only what it needs up to that limit for fast, stable charging.

What does the 100-240V 50-60Hz input actually cap in everyday use?

It accepts any mains voltage from 100 to 240 volts at 50 or 60 hertz, letting you plug it in worldwide without a voltage converter.

Will the 6.0 x 3.7mm barrel tip fit the charging port on a Zephyrus S17 GX701LWS?

Yes, the 6.0 mm outer and 3.7 mm inner diameter tip matches the DC-in jack on those models for a secure connection.
