Compatible 45 W AC adapter for Acer Aspire 3

This replacement power supply is built for the Acer Aspire 3 A315-51-31GK and A315-51-31RD notebooks. It delivers 45 W of continuous power to keep the laptop running and the battery charging. The unit ships new with a 10 ft mains cable included. It is a direct substitute for the original charger.

Steady output during extended sessions

The adapter maintains its rated 45 W under sustained load without dropping voltage or shutting down. Over-current and total-power protection circuits guard the laptop if demand spikes unexpectedly. The 100-240 VAC 50/60 Hz input range lets it operate on mains worldwide without a separate converter. A smart chip monitors the charging cycle to prevent over-charge and over-discharge stress.

Cool, quiet operation with certified safety

Over-voltage and short-circuit protections cut the output instantly if a fault appears, keeping the laptop and the brick itself safe. High-quality wires and better isolation materials reduce electromagnetic interference and heat build-up during normal use. The adapter meets FCC, CE and RoHS standards for emissions and hazardous substances. No moving parts means silent running on the desk.

Questions about this item

Does the 45W adapter run hot or draw extra power when charging all day?

The unit delivers 45W through a 10 ft cord with over-current, over-voltage and short-circuit protection to limit heat and power waste during continuous use.

What must I already have for this charger to work with my Acer Aspire 3 A315-51-31GK or A315-51-31RD?

You only need a standard wall socket supplying 100-240VAC at 50/60Hz; the adapter plugs directly into the laptop’s original DC jack.

Can I keep my older Acer power cord and use it with this 10 ft supply cable?

The replacement includes its own 10 ft mains lead, so no separate cord is required; it connects straight from the wall outlet to the laptop.
