The Laptop’s Adapter Charger
Laptop chargers and adapters consume power to keep your laptop running. Plugged chargers use electricity even when it is not charging the laptop.
Low-end and affordable laptops have 60 watts adapters since they need less power consumption.
Gaming laptops and work laptops, on the other hand, come with 90-watt adapters for higher power consumption.
Current adapters are more energy-efficient and do not consume excess power. They balance laptop wattage and its usage.
So the answer to how many watts to charge a laptop lies in the laptop’s adapter.
How Many Watts Does a Gaming Laptop Use?
If you wonder how much watts does my laptop uses, it is always 2-5 times more than a regular laptop’s power consumption.
A regular low-end or affordable laptop consumes 20-Watt to 100-Watt when the computer is at 10% battery with an unplugged charger.
An average high-end gaming laptop wattage ranges from 40-Watt to 320-Watt. Since these laptops come with specialized units and components for an enhanced gaming experience, they consume more power.
You also have to factor in its size, software, hardware, processor, and chargers when you check the wattage of a laptop.
