Can You Charge a Laptop with USB-C?

In the era of modern technology, USB-C has emerged as a versatile connector that offers a range of capabilities, including power delivery. This has led to the question of whether it’s possible to charge a laptop using a USB-C cable.

USB-C Power Delivery

USB-C Power Delivery (USB PD) is a protocol that enables USB-C ports to deliver up to 100 watts of power. This is significantly higher than the standard 5 watts provided by USB-C connections. With USB PD, it becomes possible to charge devices that require more power, such as laptops.


Not all laptops support USB-C charging. To determine if your laptop is compatible, check the following:

  • USB-C port: Verify if your laptop has a USB-C port.
  • USB-C Power Delivery: Check the specifications of your laptop to see if it supports USB-C PD.

Most newer laptops released in recent years support USB-C charging, but it’s always best to confirm.

Charging Speeds

The charging speed of a laptop via USB-C will vary depending on the power output of the USB-C charger and the power requirements of the laptop. Higher-wattage chargers will typically charge laptops faster. Some laptops may also support fast-charging protocols like Power Delivery 3.0 or Qualcomm Quick Charge, which can further increase charging speeds.

Advantages of USB-C Charging

  • Convenience: USB-C cables are smaller and more versatile than traditional laptop chargers, making them easier to carry and use.
  • One cable for all: USB-C can charge a wide range of devices, including laptops, smartphones, and tablets, eliminating the need for multiple chargers.
  • Fast charging: USB-C PD allows for faster charging speeds compared to standard USB-C connections.
  • Future-proof: USB-C is a widely adopted standard, ensuring compatibility with newer devices and peripherals.

Potential Drawbacks

  • Compatibility issues: Not all laptops support USB-C charging, and even those that do may not support high-wattage charging.
  • Charger wattage: Using a lower-wattage charger than what the laptop requires may result in slower charging or insufficient power for the laptop to operate.
  • Heat generation: High-wattage USB-C charging can generate heat, particularly in laptops that are under heavy load.


Charging a laptop with USB-C is possible for laptops that support USB-C Power Delivery. This method offers the advantages of convenience, versatility, and fast charging. However, compatibility, charger wattage, and potential heat generation should be considered before using this charging method. By verifying compatibility and using appropriate chargers, you can harness the benefits of USB-C charging for your laptop.
