65 W AC Adapter for Acer Chromebook 14

This 65 W AC adapter replaces the original charger for Acer Chromebook 14 models CB3-431-C3WS and CB3-431-C7EX. It delivers 19 V at 3.42 A and automatically adjusts to support 45 W requirements at 2.37 A. The unit accepts worldwide input voltage from 100 to 240 VAC at 50 to 60 Hz. It is a compatible replacement, not an original Acer product.

Upgrade from a lost or faulty 45 W charger

The adapter supplies 65 W output while remaining compatible with the lower 45 W specification used by some configurations. Buyers replacing a damaged 45 W unit gain extra headroom for charging under load. The jump is worth it when the original charger is missing, the cable is frayed, or the barrel connector no longer seats securely. It does not increase the laptop’s maximum charging speed beyond its designed limit.

Plug-in replacement with built-in safeguards

Installation is limited to connecting the AC mains lead and the barrel plug to the Chromebook. The adapter includes over-voltage, short-circuit and over-current protection plus a smart chip for voltage matching. The main risk is selecting the wrong tip polarity or barrel size for other Acer models; this unit is specific to the CB3-431 series. No driver or firmware steps are required.

Questions about this item

What barrel connector size does the myVolts 65 W adapter use for the Acer Chromebook 14 CB3-431?

The adapter provides a 19 V output with a 3.42 A rating and uses the standard barrel connector that fits the Acer Chromebook 14 CB3-431-C3WS and CB3-431-C7EX models.

How do I install the myVolts 65 W adapter, and what is the step users often miss?

Plug the AC cable into a 100-240 VAC wall outlet at 50-60 Hz, then connect the DC barrel plug to the Chromebook; the step often missed is ensuring the barrel plug is fully seated so the smart chip negotiates the correct 19 V 3.42 A output.

When will the myVolts 65 W adapter need replacement, and what should I watch for?

Replace the adapter if the cable frays, the barrel plug becomes loose, the brick overheats, or the over-voltage, short-circuit, or over-current protections trigger repeatedly during normal use.
