45W AC adapter for Acer Aspire and Switch models

This 45W AC adapter supplies 19V at 2.37A for compatible Acer laptops including the Aspire S7 391, V3-371 and Switch Alpha 12 SA5-271 series. It replaces the A13-045N2A unit and delivers the rated power for charging and operation. The unit is new and ready for immediate use.

Practical limits of the barrel connector interface

The barrel connector fits only the listed Acer models so it cannot charge laptops with different tip sizes or voltage requirements. Maximum output is fixed at 45W so systems that draw more power under load will not be supported. Buyers needing higher wattage or a different connector must select another adapter.
