Can You Charge a Laptop with a USB-C Phone Charger?

With the increasing popularity of USB-C ports on laptops and other devices, you may be wondering if you can use your USB-C phone charger to power your laptop as well. The answer is yes, but there are a few things you need to keep in mind.


Not all laptops are compatible with USB-C charging. To determine if your laptop can be charged via USB-C, check the manufacturer’s specifications or look for the USB-C symbol on the power port.

Additionally, your phone charger must support USB Power Delivery (PD) to be able to charge your laptop. PD is a charging standard that allows devices to negotiate and deliver higher power levels over USB-C.

Charging Speeds

The charging speed of your laptop will depend on the wattage of your phone charger. Most phone chargers provide 18W of power, which is sufficient for charging small laptops or tablets. However, for larger laptops, you may need a charger with a higher wattage, such as 60W or 100W.

It’s important to note that the maximum charging speed of your laptop is determined by its own hardware and power management capabilities. Even if you use a high-wattage charger, your laptop may not be able to charge at the maximum rate.

Safety Considerations

While using a phone charger to charge your laptop is generally safe, there are a few safety precautions you should follow:

  • Always use a genuine charger from the manufacturer or a reputable third-party brand.
  • Check the cable for any damage before use.
  • Avoid using a phone charger that is rated for a lower wattage than your laptop requires.
  • Do not leave your laptop charging unattended for extended periods of time.


Charging your laptop with a USB-C phone charger is a convenient option if your laptop is compatible. However, it’s important to consider the compatibility, charging speeds, and safety considerations before using this method. If you have any concerns, it’s always best to consult with the manufacturer of your laptop.
