If you’re like most people, you probably rely on your laptop to get through the day. But what do you do when you can’t find your charger?

Don’t worry, we’ve got you covered. Here are a few tips on how to charge your laptop without a charger.

Top 3 Ways to charge a laptop without a charger

If you find yourself in a situation where you need to charge your laptop without a charger, there are a few options available to you. Depending on the model of laptop you have, you may be able to charge it using a USB cable, an AC adapter, or by connecting it to an external battery pack.

Before trying any of these methods, it’s important to check your laptop’s manual to see if it’s designed to be charged in this way. Some laptops are not designed to be charged without a specific type of charger, and attempting to do so could damage your laptop or shorten its lifespan.

If your laptop is able to be charged without a charger, here are a few methods you can try:

  • USB charging: Many laptops can be charged via USB using either a USB charging cable or a standard USB data cable. To do this, simply connect one end of the USB cable to your laptop and the other end to either a USB port on another device (such as a computer or smartphone) or a USB power adapter.
  • AC adapter: If your laptop has an AC adapter port, you may be able to use an AC adapter from another device (such as a phone charger) to charge it. Just connect the AC adapter to the appropriate port on your laptop and plug it into an outlet. Note: That, not all AC adapters are compatible with all laptops, so you’ll need to check that the voltage and wattage output of the adapter is compatible with your laptop before using it.
  • External battery pack: Another option for charging your laptop without a charger is to use an external battery pack. These devices work by storing power in batteries and then outputting that power through a standard USB port. To use one of these devices, simply connect it to your laptop via USB and allow it to charge for a while until the battery pack is empty.
  • Power Bank: Power banks are portable devices that store energy and can be used to charge laptops, phones, and other gadgets. To use a power bank to charge your laptop, simply connect the power bank to your laptop using the included cord and then press the “power” button on the power bank.

Te Benefits & Risk of Charging Your Laptop Without a Charger

Most laptop computers come with a standard charger that plugs into an outlet and delivers power to the battery. However, there are some benefits to charging your laptop without a charger.


  • charging your laptop without a charger can extend the life of your battery. When you use a charger, the battery goes through what is known as a “charge cycle.” This means that the battery is charged up to 100%, then discharged back down to 0%, and then charged back up to 100%. This process can put a lot of wear and tear on your battery, and over time, it can shorten the lifespan of your battery.
  • charging your laptop without a charger can help you conserve energy. When you use a charger, your laptop has to convert the AC power from the outlet into DC power for the battery. This process is not 100% efficient, so some energy is lost in the conversion. When you charge your laptop without a charger, it bypasses this conversion process and doesn’t waste any energy.
  • charging your laptop without a charger can be more convenient. If you’re away from an outlet and need to charge your laptop, you can simply plug it into another device like a power bank or an external battery pack. This way, you won’t have to worry about finding an available outlet.


  • One of the biggest risks is that you could overheat and damage your laptop. When your laptop is running on battery power, it is not able to dissipate heat as effectively as when it is plugged into a power source. This means that there is a greater risk of your laptop overheating and sustaining damage.
  • Another risk of using your laptop without a charger is that you could drain the battery too low. If you allow the battery to drain completely, it can cause damage to the battery and shorten its lifespan. Additionally, if you are using your laptop for important tasks, such as work or school, running out of battery power could result in lost data or an interruption in your work.

The bottom Line:

Overall, it is best to avoid using your laptop without a charger whenever possible. If you must use it without a charger, be sure to monitor the temperature of your laptop and keep an eye on the battery level. If possible, plug it in to charge periodically to help minimize the risks.
