Questions about this item

How do I connect the 3.0mm yellow tip to the charging port on my Acer Chromebook C720?

Align the 3.0mm x 1.1mm yellow tip with the DC jack and push straight in until it seats firmly; the step people miss is verifying the tip colour matches the original charger before inserting.

When will the detachable power cord or the adapter brick need replacement?

The IEC power cord can be swapped if the plug or cable frays; the sealed adapter brick itself has no user-serviceable parts and is replaced as a unit when output voltage drops or the unit overheats.

At what load does the adapter hit its thermal limit during continuous use?

Sustained loads near the 65W rating will cause the brick to reach its thermal ceiling first; operating at the 45W level (19V 2.37A) runs cooler and extends continuous-run time.
