Questions about this item

What DC connector dimensions does this 19 V 3.42 A adapter use?

The barrel plug has a 1.1 mm internal diameter and a 3.0 mm external diameter.

Will the 65 W unit fit inside the Acer Chromebook C720 chassis?

No, this is an external power brick that connects via the barrel jack; it does not mount inside the laptop.

How do I install the replacement charger, and what step is often missed?

Plug the AC cord into the brick, connect the barrel tip to the Chromebook, then plug the mains lead into a 100-240 V outlet; the step often missed is seating the barrel connector fully until it clicks.
