This guide covers the essentials of laptop and usb-c pd charging in one place — the standards, trade-offs, and practical buying advice that matter most.
- USB-C Power Delivery now scales from 15W to 240W, covering everything from tablets to high-performance workstation laptops on a single standard.
- GaN chargers deliver the same power in a smaller, cooler-running package compared to traditional silicon-based designs.
- Matching or exceeding a laptop’s rated wattage prevents battery drain under heavy load — going lower means the battery makes up the difference.
The rest of this section breaks each of these topics down in more depth, covering specific devices, standards, and buying scenarios.
