Replacement Acer Chromebook 45W Adapter

This 45 watt AC adapter replaces the original charger for Acer Chromebook models including CB3-431, CB5-132T, C720 and related 11, 13, 14 and 15 inch variants. It suits students, mobile workers and anyone needing a spare power supply for compatible Acer devices. The unit delivers 19 volts at 2.37 amps from a 100 to 240 volt input range.

45W Output With 10 Foot Cable

The adapter provides 45 watts continuous power, sufficient for charging and running supported Chromebooks under normal workloads. A 10 foot / 3 metre cable gives generous reach between wall outlet and desk, reducing the need for extension leads. Headroom is limited to the rated 45 watts; systems drawing more current will not be supported.

Compact Design With Detachable AC Cord

High-quality copper wire construction supports efficient energy transfer while the detachable mains lead makes packing for travel straightforward. The brick is small enough to slip into a laptop bag alongside the Chromebook. Normal warmth during operation is expected; the supplier advises against disassembly and use in extreme temperatures.

Questions about this item

Will this 19V 2.37A 45W adapter work with my older Acer Chromebook C720 that uses the same barrel tip?

Yes, the adapter lists the C720 among its compatible models and delivers the required 19V 2.37A output, so it will power that unit correctly.

How can I verify the charger is functioning properly once I plug it in?

The Chromebook should show the charging indicator and the battery percentage should increase; the brick warming slightly during use is normal.

Does the package include both the AC wall cable and the DC output cord, or must I buy the wall cord separately?

The 10 ft / 3 m cable mentioned is the combined AC and DC lead, so no separate wall cord is required.
