Other Ways to Charge Your Laptop Without Charger

Besides the top 3 ways that we have mentioned above, there are some other different ways that can be used to charge your laptop, without any laptop chargers around, if you aren’t in possession of its original charger.

2. Charging the Battery Externally

If all of the above options of a backup power supply aren’t available, you can always get an external laptop battery charger. External battery chargers will allow you to charge your laptop’s battery externally as long as you have a USB type C recharge port available. However, you must also find the right charger for your battery, as the compatibility varies for each charger. So, you must find the right charger for your laptop’s battery.
