240 W Dell laptop adapter

This 240 W AC adapter delivers 19.5 V at 12.3 A for compatible Dell laptops including G7 17 7790, Inspiron 15 7577, 7588 and Precision 15 7510, 7520 models. It replaces original 180 W, 230 W and 240 W Dell chargers with a 7.4 x 5.0 mm centre-pin barrel plug. The unit includes a 6 ft AC cord and a 6 ft DC cord for extended reach.

7.4 x 5.0 mm barrel limitation

The connector is a 7.4 x 5.0 mm barrel with a centre pin and will not fit Dell systems that require the larger 9.0 x 6.2 mm tip. Input voltage ranges from 100 V to 240 V at 50 Hz to 60 Hz for worldwide use, but the adapter cannot supply power to devices demanding more than its rated output. It is not a substitute for 280 W, 300 W or 330 W Dell power supplies.

240 W capacity boundary

The adapter comfortably powers and charges supported Dell laptops that ship with 180 W, 230 W or 240 W bricks, providing continuous output up to 240 W. It runs out of headroom for any system that draws above 240 W, such as configurations requiring 280 W, 300 W or 330 W adapters, and will not meet the power demands of those higher-wattage models.
