Will this 330W adapter fit my Acer Predator gaming laptop?

This adapter will fit your Acer laptop if your original charger requires a 5.5x1.7mm DC plug and operates at 19.5V. You must check the sticker on the bottom of your laptop or your old charger to verify the voltage and plug dimensions before purchasing.

Why is the AC power cord not included with this adapter?

This product is sold as a replacement power brick, allowing customers to reuse their existing wall cables to reduce electronic waste. If you need a new wall cable, you can purchase the compatible computer power cable directly from our website.

Can I use this adapter if my laptop requires a 5.5x2.5mm plug?

No, you cannot use this adapter for a device requiring a 5.5x2.5mm plug. The inner pin diameter of this adapter is 1.7mm, which will not fit properly into a 2.5mm socket, leading to a loose connection and potential electrical arcing.

Is it safe to use a 330W adapter if my original charger was only 230W?

Yes, it is completely safe to use a 330W adapter on a laptop that originally came with a 230W charger, provided the voltage (19.5V) and plug size match. The laptop will only draw the current it needs, and the higher-capacity adapter will simply run cooler and more efficiently.

Can I bring my laptop to your Hong Kong store to test the charger?

Yes, you are highly encouraged to bring your laptop to Sun Cheong Computer Co. Ltd. (新昌電腦有限公司) in Sham Shui Po. Our technical staff will help you test the physical fit of the 5.5x1.7mm plug and verify the charging status before you make a purchase.

Full Product Description

Heavy-Duty 330W Power for Gaming Laptops

This Chicony 330W Power Adapter provides the immense wattage required to keep high-end gaming laptops and mobile workstations running at peak performance. Manufactured by Chicony, a trusted OEM provider for major brands like Acer, it delivers a highly stable 19.5V and 16.92A output. This robust power delivery prevents frame rate drops, battery drain during heavy gaming sessions, and unexpected system shutdowns caused by insufficient power.

Precision 5.5x1.7mm DC Connector

The adapter is equipped with a specialized 5.5x1.7mm DC barrel plug, which is the exact standard required by many Acer Predator and Nitro series laptops. This specific connector size (5.5mm outer diameter, 1.7mm inner diameter) ensures a snug, secure fit into your laptop's charging port, preventing accidental disconnections. The durable, thick DC cable is heavily shielded to reduce electromagnetic interference and withstand daily bending.

Pro Tip from Our Technicians

Our Sham Shui Po technical team wants to remind you that this 330W Power Supply does not include the AC wall power cord (the cable that connects the adapter brick to the wall outlet). You can reuse your existing standard C13 power cable, or you can purchase a new, high-quality replacement directly from us here: Computer Power Cable. Furthermore, because 330W adapters generate significant heat under full load, always place the power brick on a hard, well-ventilated surface rather than on carpets or beds.
