myVolts 19V 3.42A 65W AC Adapter 3.0mm*1.1mm for Acer Chromebook

19 V 65 W AC adapter for Acer Chromebook

This 19 V 3.42 A power supply delivers up to 65 W and accepts 100–240 V AC input. It is built for Acer Chromebook models including 11, 13, 14 and 15 inch variants such as CB3, CB5, C720, C738T, C740, R11, Spin and Swift series. The barrel connector measures 3.0 mm outer by 1.1 mm inner diameter with an 8.5 mm length.

3.0 mm barrel connector and 1.2 m AC cord

A 1.2 m mains cord is included so the adapter reaches wall outlets without strain. The 3.0 mm × 1.1 mm tip fits the listed Acer models precisely, preventing loose connections that cause intermittent charging. Copper conductors and high-temperature resistant materials support stable current delivery. OCP, OVP, SCP and OTP circuits protect against over-current, over-voltage, short-circuit and over-temperature events.

Replaces 40 W and 45 W Acer chargers

The unit also covers 19 V 2.15 A 40 W and 19 V 2.37 A 45 W original adapters, so one brick serves multiple legacy power ratings. It is not for laptops that require a different voltage, a larger barrel diameter or a USB-C power profile. Buyers whose devices use a proprietary connector other than 3.0 mm × 1.1 mm should verify compatibility before ordering.
