Compatible Dell G-series and Inspiron models

This 240W AC adapter fits Dell G3, G5, G7, G15 and G16 laptops as well as select Inspiron units. It delivers 19.5V at 12.3A through a 7.4 x 5.0 mm barrel plug with a centre pin. The unit replaces original 180W, 230W and 240W chargers but does not support 280W, 300W or 330W requirements. It is intended for owners of the listed Dell models who need a direct replacement power supply.

Sustained 240W delivery and input range

The adapter accepts worldwide AC input from 100V to 240V at 50Hz or 60Hz and maintains a continuous 240W maximum output. Internal protection circuits filter voltage spikes and limit output current to protect the laptop during extended charging sessions. High power efficiency keeps the supply stable whether the system is under load or idle. The ruggedised case is sealed against moisture and high humidity for durable mobile use.

Thermal behaviour and cable reach

A 6-foot UL-listed three-prong AC cord plus a 6-foot DC cable give a combined reach that reduces the need for extension leads. The enclosure measures 7.75 x 3.75 x 1.75 inches and weighs 46.20 oz, allowing it to dissipate heat passively during normal operation. No fan noise is produced because the design relies on convection cooling. The adapter powers the laptop and charges the battery whether the system is on or off.

Questions about this item

How hot or loud does the 240W 19.5V 12.3A adapter get when running all day?

The ruggedised case is sealed against moisture and high humidity, and internal safety features limit output voltage and current, so the brick stays cool and silent during continuous use.

Which Dell laptops must I already own for the 7.4 x 5.0 mm centre-pin tip to fit?

Compatible models include G3 15 3579 3590, G5 15 5500 5587 5590, G3 17 3779, G7 15 7588 7590, G7 17 7790, G15 5510 5511 5515 5520 5525, G16 7620, and Inspiron i7588 i7577.

Will this 240W brick safely replace the 180W charger that came with my older G3 15 3579?

Yes — it replaces Dell 180W, 230W and 240W adapters, but it does not replace 280W, 300W or 330W units.
