85 W Dell AC adapter with yellow square tip
This 85 W Dell power supply delivers 20 V at up to 11.8 A through a yellow square connector. It is built for users who need a replacement or spare charger for compatible Dell laptops that require this specific tip geometry and wattage.
Replaces worn or lost 85 W Dell chargers
The adapter steps in when an original 85 W unit fails, is misplaced or a second charger is wanted for travel. The jump is worth it when the laptop demands 20 V 85 W input and the yellow square tip matches the device jack; lower-wattage bricks will not supply enough power for full performance or charging under load.
Limited to devices accepting 20 V 85 W via yellow
The barrel connector and 85 W ceiling restrict use to laptops designed for this exact voltage, current and tip profile. Machines that require higher wattage, a different voltage or an alternative connector — such as USB-C Power Delivery or a larger barrel — cannot use this adapter safely or at all.
