What this adapter does

The myVolts 19V 7.1A 135W unit replaces the original Acer power supply for listed Aspire V17 Nitro and Predator Helios 300 models. It delivers 19 volts at 7.1 amps through a 5.5 mm by 1.7 mm barrel connector and accepts 110 to 240 V input for worldwide use.

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.
