45 W 19 V AC adapter for Acer Chromebook

This 45 W AC adapter delivers 19 V at 2.37 A through a 3.0 × 1.1 mm DC plug. It is built for Acer Chromebook 11, 13, 14 and 15 series as well as Aspire R, S, V, Switch, Swift and Spin ultraportables listed by the supplier. The unit accepts 100–240 V AC input for worldwide use.

Plug-in replacement with built-in safety protections

Installation is a direct swap: connect the barrel plug to the laptop and the IEC lead to a wall outlet. The adapter includes over-current, over-voltage, short-circuit and total-power protection circuits and is 100 % tested before delivery. The only common issue is ordering the wrong tip size; verify the 3.0 × 1.1 mm dimensions before purchasing.

Check your laptop’s voltage.

Confirm the original charger specifies 19 V and 2.37 A output and uses a 3.0 × 1.1 mm barrel connector. Ensure the device appears in the compatible model lists for Chromebook CB3, C730, C731, C738T, CB5 series or Aspire R5-471T, V3-331, V3-371, Switch SW5-171 and related SKUs. This adapter is not for laptops requiring higher wattage, different voltage or a larger tip.

Questions about this item

How can I confirm the adapter is delivering 19V and 2.37A after plugging it in?

The LED on the adapter body lights solid when the unit is powered; the laptop battery icon should show charging within seconds.

What comes in the box and is a mains lead included?

The package contains one AC adapter with a fixed 3.0*1.1 mm DC plug; a detachable IEC C7 mains cable is not supplied.

My Acer model is listed as CB3-131 and also as C738T — which entry do I match?

Both model codes appear in the compatibility list, so either reference confirms the adapter will fit.
