What this adapter is and who it suits

This is a DELL CT-1250 AC adapter rated at 85 watts with a 20 volt, 11.8 amp output. It is a new, corded electric unit weighing 0.283 kilograms and carries an ETL mark. The adapter is intended as a replacement power supply for compatible laptops that require a 20 volt input at this wattage.

Check your laptop before ordering

Confirm that your device accepts a 20 volt DC input and draws no more than 85 watts. Verify the barrel connector size matches either the 4.5mm by 3.0mm or 7.4mm by 5.0mm tips used on this model. The unit operates from a 12 volt DC vehicle socket, so it is not suitable for mains wall outlets without a separate inverter.

What the bundled items change

Two interchangeable barrel tips are included to fit the two connector sizes listed above. This allows the same adapter to serve multiple laptop models without buying separate cables. No software, driver disc or additional accessories are mentioned in the specifications.
