Use the tool

Add a chosen planning margin to your laptop’s stated power requirement before you compare charger options.

How the estimate works

Planning watts = rated watts × (1 + headroom percentage ÷ 100). Wattage alone does not confirm charger compatibility.

About this tool

Add a planning margin to a power requirement you read from your laptop documentation or existing adapter. The result is a planning value, not a compatibility check. USB-C Power Delivery profiles, cable ratings, barrel connectors, voltage and manufacturer restrictions all matter; wattage alone is not enough. Confirm the exact laptop model, voltage, connector and supported charging protocol before buying. The marketplace links are searches for candidate products and do not certify fit or safety.
