# Why Do USB-C Chargers Power the Same Laptop at Different Speeds?

I’ve tried two USB-C chargers with my laptop, and one charges noticeably faster even though both seem to work normally. The chargers have different wattage ratings, but I’m also wondering whether the cable or the laptop’s current workload affects the result.

When comparing **USB-C charging speeds**, which specifications actually matter most?
