2-Power SK90A195231 65W 19V 3.42A AC Adapter

65W AC Adapter for Acer Laptops

This 65-watt power supply delivers 19 volts at 3.42 amps for compatible Acer Aspire, Swift, Spin and Chromebook models. It accepts a universal 100-240 volt input at 50-60 hertz for worldwide use. The barrel connector measures 3.0 millimetres outer diameter by 1.1 millimetres inner diameter. Buyers whose laptops require a different tip size or a higher wattage brick should look elsewhere.

Output capacity and headroom

The adapter provides 65 watts of continuous power, matching the original charger rating for the listed Acer series. It comfortably runs ultraportable and mainstream models such as the Aspire 3, Aspire 5, Swift 3 and Spin 5 during typical workloads and charging. Under sustained heavy loads or with larger 15 and 17 inch configurations the unit may reach its thermal limit and throttle output. Systems that ship with an 85 watt or 90 watt brick will not receive full performance from this model.

Build integration and cable freedom

A detachable AC mains cord is included so you can swap the plug for local sockets without replacing the whole brick. The 3.0 by 1.1 millimetre barrel plugs directly into the laptop’s DC jack; no additional converters are needed for the models named in the compatibility list. Pure copper conductors and a heat-resistant plum-flower connector shell improve durability during frequent connect-disconnect cycles. Units requiring USB-C Power Delivery or a proprietary slim-tip connector are not supported.
