Questions about this item

How do I connect the 3.0*1.1 mm tip to my Chromebook C720 without forcing it?

Align the 3.0 mm outer diameter and 1.1 mm inner pin with the charging port, then push straight in until seated; angling the plug bends the centre pin and breaks contact.

Which part of this adapter will wear out first and need replacing?

The detachable power cord cable typically frays at the strain relief before the AC adapter body fails, so keep a spare cord on hand.

What limits continuous charging on the C740 during heavy workloads?

The adapter delivers a fixed 100 % rated output; sustained maximum draw causes the brick to hit its thermal ceiling and throttle before the Chromebook battery saturates.
