Replacement AC Adapter

The POWER-FENG ADP-180MB K supplies 20 volts at 9.23 amps through a 5.5 mm by 1.7 mm barrel connector. It matches the original charger for Acer Predator Helios 300 models G3-571, G3-572, PH315-51, PH315-52, PH317-51 and PH317-52. Buyers needing a different voltage or tip size should look elsewhere.

Universal Input and Thermal Design

The unit accepts 100 to 240 volts at 50 to 60 hertz for worldwide mains compatibility. A sealed enclosure handles heat passively without a fan, so operation stays silent on a desk. Normal use keeps the case warm but within expected limits for a 180 watt class adapter.

Sustained Load Behaviour

Under continuous gaming or rendering loads the brick maintains the rated 20 volt output without cycling. Voltage droop stays minimal during extended sessions thanks to the robust internal design. It is not suited for devices that require more than 9.23 amps or a different connector polarity.

Questions about this item

How do I install the ADP-180MB K adapter on my Predator Helios 300 and what step do people often miss?

Plug the 5.5 mm by 1.7 mm barrel connector firmly into the laptop's DC-in jack until it seats fully; the step people miss is verifying the tip clicks into place before routing the cable.

What maintenance or replacement will this 20 V 9.23 A power supply need over time?

The detachable AC cord and barrel tip are the wear items; inspect the cord for fraying and the tip for looseness, replacing either piece if the connection becomes intermittent.

What limit appears first when the adapter runs continuously at full load?

Sustained 180 W output will hit thermal limits first; the brick throttles or shuts down if ventilation is blocked, so keep the unit on a hard, flat surface during heavy gaming sessions.
