Genuine Acer 330W AC Adapter for Predator Laptops

This is a new genuine Acer power supply rated at 330 watts with a 19.5V output. It includes the AC power cord and supports a 100-240V input range for worldwide use. The unit matches part numbers KP.33001.001, KP.33003.001 and PA-1331-91. It is built as a direct replacement for the original charger supplied with compatible Predator models.

Fits Predator 17X, 21X, Helios 500.

The adapter suits owners of the listed Predator 17X, 21X, Helios 500, Helios 700 and Triton 900 machines who need a factory-spec replacement. Buyers with laptops that require a different voltage, a lower wattage rating or a proprietary connector shape should look at another unit. It is not for ultraportable or mainstream notebooks that draw less power.

330W output at 19.5V 16.9A

The single specification that decides fit is the 330W output delivered at 19.5V and 16.9A. Your laptop must accept exactly this voltage and be designed for a 330W brick. If the original charger shows a different wattage or voltage, this adapter will not work correctly.
