Dell 240W Alienware Charger

Dell 240W Alienware Charger

A Dell 240W Alienware Charger is the right power class for several Alienware systems that were designed around Dell's 240W adapter. Dell documents a 19.5V output at 12.31A with a 7.4 x 5.1mm barrel connector on compatible models, so matching wattage and connector type matters before you order.

Which Alienware laptops use a 240W adapter?

Dell lists a 240W option for systems including the Alienware m15 R2, m15 R7, m17 R2 and m17 R4. Some configurations from the same model family can ship with a different wattage, especially when CPU or GPU options change, so the laptop model alone is not always enough to confirm the adapter.

Why the full 240W rating matters

Gaming workloads can keep both the processor and discrete graphics active for long periods. Using an under-rated adapter may cause slower battery charging or reduced performance while the system is under load. The correct 240W class supplies 19.5V at up to 12.31A through Dell's larger barrel connector, giving the laptop the power budget it was designed to request.

• 240W maximum output
• 19.5V rated DC output
• 12.31A continuous output
• 7.4 x 5.1mm Dell barrel connector

Confirm the fit before checkout

Alienware power requirements vary by exact revision and configuration. Check the label on your existing adapter and the model shown on the underside of the laptop before replacing it.
