Can You Charge a Laptop With Another Laptop?

While it is not a common practice, it is possible to charge one laptop using another laptop.
This can be useful in an emergency or when you don’t have access to a power outlet.

How to Charge a Laptop With Another Laptop

There are two methods to charge a laptop with another laptop:

• Using a USB-C cable:
  This method is only available if both laptops have USB-C ports that support power delivery.
  To charge a laptop using a USB-C cable, connect the USB-C cable to the USB-C port on both laptops.
  The laptop will automatically start charging.
• Using a USB-A to USB-C cable:
  This method can be used if the charging laptop has a USB-A port and the other laptop has a USB-C port.
  To charge a laptop using a USB-A to USB-C cable, connect the USB-A end of the cable to the USB-A port on the charging laptop.
  Then, connect the USB-C end of the cable to the USB-C port on the other laptop.
  The laptop will automatically start charging.

Things to Consider

Here are a few things to consider when charging a laptop with another laptop:

• Power output:
  The charging laptop must have a USB-C port that supports power delivery or a USB-A port with a high enough power output to charge the other laptop.
• Battery life:
  The charging laptop’s battery will drain faster when charging another laptop.
  The amount of time that the charging laptop’s battery will last depends on the power output of the USB-C port and the battery capacity of the other laptop.
• Heat:
  Charging a laptop with another laptop can generate heat.
  Make sure that both laptops are well-ventilated to prevent overheating.

Conclusion

Charging a laptop with another laptop is possible as long as you have the right cables and consider the power output, battery life, and heat.
This can be a useful way to charge your laptop in an emergency or when you don’t have access to a power outlet.
