330W Acer laptop charger

This 330W AC adapter supplies 19.5V at 16.92A through a 5.5mm by 1.7mm barrel connector. It is built for Acer Predator Helios and Triton models as well as Nitro 15, 16 and 17 series notebooks. The unit accepts 100 to 240V input at 50 to 60Hz for worldwide use. A three-prong IEC C5 power cord is included in the package.

Sustained-load behaviour

The adapter delivers its full 330W rating continuously thanks to built-in protection against overcurrent, overvoltage, short circuit and internal overheating. A smart microchip regulates output to keep voltage stable during extended gaming or rendering sessions. The reinforced elastomer cable sheath resists wear from repeated bending and dragging. UL and RoHS certified connectors ensure consistent electrical contact over time.

Replaces original 330W brick

This unit matches the PA-330W specification and connector polarity, so it substitutes a lost or damaged factory charger without modification. The jump is worth it when the original adapter fails, shows frayed cables or trips its protection under load. Buyers who need a lower-wattage travel unit or a USB-C power source will not be served by this model.

Questions about this item

Does the 330W 19.5V adapter run hot or make noise during all-day use?

The unit includes internal overheating protection and a smart microchip that regulates power delivery, helping keep temperatures stable during continuous operation.

What must I already own for this 5.5mm x 1.7mm charger to work with my Acer laptop?

You need a compatible Acer model such as Predator Helios 18, 16 or 15 series, Predator Triton 17 X PTX17-71, or Nitro 17, 16, 15 series that accepts a 19.5V 16.92A barrel connector.

Will this 330W power adapter work alongside my older Acer Nitro 15 that originally used a lower-wattage brick?

Yes, the charger supports 100-240V AC input and delivers 19.5V 16.92A through the same 5.5mm x 1.7mm tip, so it can power compatible Nitro 15 models that match the voltage and connector.
