DELTA 19V 2.37A 45W AC Adapter

This DELTA AC adapter delivers 19V at 2.37A for a 45W output through a 3.0 x 1.0mm barrel connector. It is built for Acer Chromebook CB3, CB5, C720, C730, C731, C735 and C810 series notebooks. The unit includes a US cable plug and carries UL safety testing. It serves owners who need a direct replacement for a lost or failed original charger.

Replaces 40W 2.1A chargers

The 45W rating also covers earlier 40W 2.1A models used across the same Acer families. Swapping to this adapter is worth it when the original 40W unit is unavailable or when the higher current margin reduces thermal stress on the power brick. It fits the identical 3.0 x 1.0mm tip so no cable change is required. Buyers whose laptops demand a larger connector or a different voltage cannot use this model.

45W capacity for Chromebook loads

At 45W the adapter comfortably powers the listed Chromebooks and Aspire R5 / Spin models during typical browsing, video playback and charging. Headroom remains for peripheral draw through the laptop's USB ports. It runs out when a system demands more than 45W, such as larger gaming laptops or workstations with discrete graphics. Those buyers need a higher-wattage supply with the correct tip.

Questions about this item

What connector size does this 45W adapter use to fit the Acer Chromebook?

The adapter has a 3.0 x 1.0 mm black barrel tip that matches the charging port on the listed Acer Chromebook and Aspire models.

How is the adapter connected to the laptop and mains, and what step is often missed?

Plug the US mains cable into the wall, then push the 3.0 x 1.0 mm barrel firmly into the laptop until it seats; the step often missed is not pushing the tip in fully, which leaves the connection intermittent.

When will the detachable mains cable need replacing?

Replace the US cable if the plug pins bend, the insulation cracks, or the connector at the brick end becomes loose; the brick itself should be replaced if output voltage drops below 19 V or the unit overheats.
