Avoid Generic Laptop Chargers

While the construction of a laptop charger might seem simple, picking a generic laptop charger versus one from the original equipment manufacturer (OEM) could damage your laptop. Manufacturer-made computer chargers are designed to safely convert the alternative current (AC) power from an outlet into the direct current (DC) your laptop requires to keep charge.

A generic laptop charger may not properly charge the lithium-ion battery in your laptop, which could result in overheating. Most manufacturer-recommended laptop power supply equipment undergoes rigorous testing to ensure safety. Although generic laptop chargers may cost less initially, their lower-grade components and construction aren't designed to last for long.
