Power specification and target device

This 85 watt AC adapter delivers 20 volts at 11.8 amps through a 3.0 millimetre barrel tip. It is intended for users who need a replacement charger for compatible Acer Chromebook and Aspire models that accept a 19 volt 3.42 amp input.

Behaviour under continuous use

The unit supplies a steady 65 watt output during extended charging sessions and includes short-circuit, over-voltage, over-current and over-heating protection. CE, FCC and RoHS certification confirms compliance with recognized safety standards for daily operation.

Connector and compatibility check

Verify that the laptop uses the 3.0 millimetre by 1.1 millimetre small tip; the adapter will not fit older 5.5 millimetre barrels or USB-C ports. Confirm the device appears in the supported model list such as Chromebook 11 C720 series, Chromebook 13 CB5 series, Chromebook 15 CB3 or CB5 series, and Aspire 5 A515 or A315 models before ordering.
