Who it suits and who should look elsewhere

This adapter suits owners of the exact Acer model numbers shown in the compatibility list who need a direct replacement with the same voltage, current and connector. Buyers whose laptops require a different voltage, a higher wattage, a USB-C PD input or a different barrel size should look elsewhere.

Check before ordering

Confirm that your laptop’s original charger is rated 19 V 7.1 A 135 W and uses a 5.5 mm by 1.7 mm plug. Verify the model number against the supported list including Aspire V17 Nitro VN7-792G and Predator Helios 300 G3-571 series. Ensure the AC cord you will use matches your local mains plug.

Questions about this item

Which laptop models accept the 5.5 x 1.7 mm barrel connector on this 135 W adapter?

The connector fits Acer Aspire V15 Nitro VN7-593G series, Aspire V17 Nitro VN7-793G series, Predator Helios 300 G3-571 and G3-572 series, and Predator 17 PH317-51 series laptops listed in the compatibility data.

Will this 19 V 7.1 A unit safely replace the original PA-1131-16 charger on a Predator Helios 300 G3-571?

Yes — it matches the 19 V 7.1 A 135 W rating and includes short-circuit, over-voltage, over-current and over-heating protection, so it operates as a direct replacement.

How can I confirm the adapter is delivering power correctly after plugging it in?

The laptop charging LED should illuminate and the battery icon in Windows must show “Plugged in, charging” within a few seconds of connection.
