65W 19V AC adapter for Acer Chromebooks

This 65-watt power supply delivers 19 volts at 3.42 amps through a 3.0×1.1 mm barrel connector. It replaces the original charger for a wide range of Acer Chromebook 11, 13, 14 and 15 models including the C720, C730, C740, C810 and CB3 series. Buyers who need a different voltage or connector size cannot use this adapter.

Thermals noise and power draw

The unit accepts 100–240 V AC input at 50 or 60 Hz and draws up to 2.4 amps. It meets CE, FCC, RoHS and UL certified standards for safety and efficiency. No active cooling fan is fitted so operation is silent. Users who require a higher wattage output for gaming laptops will find this unit insufficient.

Compatibility list and certifications

The bundled documentation lists dozens of specific Acer model numbers such as CB3-431, CB5-132T, C720P-2625 and C910-C37P to simplify selection. A 30-day full refund and a one-year free exchange for defects are offered by the manufacturer. Shoppers who want a USB-C power delivery charger should look elsewhere.

Questions about this item

How do I install the 3.0×1.1 mm connector on my Chromebook 11 and what step is often missed?

Align the 3.0 mm outer and 1.1 mm inner diameters with the laptop's DC jack, push straight in until it seats firmly, then plug the AC cord into a 100-240 V outlet — the step many miss is confirming the 19 V 3.42 A output matches the original charger before powering on.

What maintenance or replacement will this 65 W adapter need over time?

The adapter itself has no user-serviceable parts; expect to replace the unit if the cable frays near the 3.0×1.1 mm plug or the brick stops delivering 19 V 3.42 A after extended daily use.

What limit appears first when this charger runs continuously at 65 W?

Sustained 65 W output will cause the brick's internal temperature to rise until its thermal protection engages, temporarily reducing power until the unit cools.
