Laptop chargers have two parts: a transformer and a power cord. The transformer is the brick that converts the current from your power outlet from AC to DC, and the power cord connects the charger to the outlet. Over time, transformers can overheat, which can cause internal damage.
What is inside a laptop charger?
A simple AC adapter consists of a transformer, a rectifier, and an electronic filter. The transformer initially converts a relatively high-voltage alternating current that is supplied by an electrical outlet to a lower voltage suitable for the device being powered.
