Not all Dell laptop chargers will work on all Dell laptops, because the individual models vary in power source requirements. The chargers, while paired with compatible models, are designed to work with all laptops that use the same type of connection and require the same power output. For example, some Dell laptops may only require 35 Watts to operate, whereas others may need over 100W. A Dell charger may work with a laptop that it wasn’t intended to work with, but the difference in power output may damage the laptop. Writer Bio
