myVolts 19V 3.42A 65W AC Adapter 3.0mm 1.1mm Black Tip

Replacement charger for Acer Chromebook 11

This 65 W AC adapter supplies 19 V at 3.42 A and is built for Acer Chromebook 11 models including C720, C730, C740, CB3 and CB5 series. It also fits Acer Switch Alpha 3 SA5-271, SW312-31 and SF313-51 devices, plus TravelMate Spin B1 B118-R and Aspire Switch 11 and 12 convertibles. The unit ships new with a detachable mains cable included.

100–240 V input covers global mains voltages

The adapter accepts 100 V to 240 V at 50 Hz or 60 Hz, so it works on household power worldwide without a separate voltage selector. Output is fixed at 19 V 3.42 A for 65 W maximum, and the supply is also compatible with 19 V 2.37 A 45 W loads. No other output voltages or current profiles are provided, so the device must match the laptop's exact requirement.

3.0 mm x 1.1 mm black round tip ensures correct

The barrel connector measures 3.0 mm outer diameter by 1.1 mm inner diameter with a black tip, matching the port on the listed Acer models. A mismatched tip will not seat properly or could deliver incorrect polarity, so visual confirmation against the original charger is essential before use. The moulded strain relief and standard IEC inlet on the body support daily plugging and unplugging without cable fatigue.
