Can You Charge a Laptop via USB-C? The Ultimate Guide

USB-C has emerged as a versatile port that not only transfers data but also delivers power to devices. With its slim and reversible design, USB-C has become increasingly popular in laptops, smartphones, and other electronic devices. One common question that users have is: can you charge a laptop via USB-C?

Understanding USB Power Delivery

The answer to this question lies in the concept of USB Power Delivery (USB PD). USB PD is a specification that defines how power can be delivered over USB cables and connectors. It enables devices to negotiate and deliver varying levels of power, up to 100 watts.

To support USB PD, a device must have a compatible USB-C port and a power delivery controller. The power delivery controller manages the negotiation and monitoring of power delivery between the device and the power source.

Can You Charge a Laptop via USB-C?

Yes, you can charge a laptop via USB-C if the following conditions are met:

Laptop supports USB-C charging: The laptop must have a USB-C port that supports USB PD.
Charger supports USB-C PD: The charger or power adapter must be capable of delivering power via USB-C PD.
Cable supports USB-C PD: The USB-C cable used to connect the laptop and charger must be rated for USB-C PD.

Power Delivery and Charging Speeds

The power delivered via USB-C PD varies depending on the specifications of the device and charger. The most common power levels are:

5V at 3A (15W)
9V at 3A (27W)
12V at 3A (36W)
15V at 3A (45W)
20V at 5A (100W)

The higher the power delivered, the faster the charging speed. However, it’s important to note that the actual charging speed is also influenced by the laptop’s battery capacity and charging circuitry.
