DBTLAP 19 V 3.42 A Adapter for Acer C720

This DBTLAP AC adapter delivers 19 V at 3.42 A through a 3.0 mm by 1.1 mm barrel tip. It is built as a direct replacement charger for Acer C720 and C720P Chromebooks. The unit ships new with the detachable mains cord included. Each item is tested before dispatch to confirm correct output.

Replaces a lost or faulty original charger

If the factory power brick has failed, been misplaced or shows damaged cabling, this adapter restores full charging function without modification. The jump is worth it when the original part is unavailable or the cost of an OEM unit is disproportionate. Buyers who need a different voltage, amperage or tip geometry should verify their model number first.

Steady output during continuous charging

The adapter maintains its rated 19 V 3.42 A while the laptop battery charges and the system runs typical workloads. No thermal throttling or voltage sag is specified in the supplied data. Users who require sustained loads beyond normal Chromebook operation should confirm the power envelope matches their use case.

Questions about this item

What barrel-plug size does the Acer C720 C720P adapter use?

The connector measures 3.0 mm outer diameter by 1.1 mm inner diameter, matching the original charger specification for those Chromebook models.

How do I install the replacement adapter without damaging the port?

Align the 3.0*1.1 mm tip straight with the DC jack, push gently until it seats fully, then route the cord so the brick hangs free without pulling sideways on the socket.

When should I replace the power cord or adapter for my C720 C720P?

Replace the unit if the cable shows exposed wires near the plug, the brick becomes unusually hot during normal 19 V 3.42 A operation, or the Chromebook only charges when the cord is held at a specific angle.
