Compatible Dell models

This 65 W AC adapter fits Dell Chromebook 3181 and Latitude 3190, 5300, 5400, 5500, 7300 and 7400 laptops. It accepts 100-240 V input at 1.6 A and delivers 19.5 V at 3.34 A. The unit is also compatible with 45 W requirements. It is a new replacement charger supplied with a power cord.

Sustained delivery

The adapter provides a continuous 65 W output through over-voltage, over-current and short-circuit protection circuits. These safeguards maintain stable voltage and current during extended charging sessions. The 100-240 V, 50-60 Hz input range allows consistent operation across different mains supplies.

Thermals and noise

The compact, lightweight design uses passive cooling with no moving parts, so it runs silently. Protection circuits limit heat build-up by cutting output if voltage, current or a short circuit exceeds safe thresholds. Normal use stays within the rated 65 W without active airflow.

Questions about this item

How much heat or noise does the 65 W adapter produce when powering a Dell Latitude 7400 all day?

The adapter has no fan, so it runs silently; its OVP, OCP and SCP protection circuits keep temperatures stable during continuous 65 W or 45 W loads.

What must I already own to use this adapter with my Dell Chromebook 3181?

You only need a standard wall socket and the laptop itself — the box includes the AC adapter and a detachable power cord.

Will this 19.5 V supply work safely with an older Dell Latitude 3190 that originally used a 45 W charger?

Yes — the adapter is rated 65 W and explicitly noted as 45 W compatible, so it will power the 3190 without issue.
