How to Charge 18650 Battery Without Charger?

18650 batteries are a type of lithium-ion battery that is commonly used in high-drain devices such as flashlights and electric vehicles. While these batteries are typically charged using a dedicated charger, it is possible to charge them without one using a few different methods.

Use a USB Power Bank

One way to charge 18650 batteries without a charger is to use a USB power bank. Power banks usually have multiple ports that can be used to charge various devices, including 18650 batteries. To charge the battery, simply connect it to the power bank using the appropriate cable and turn on the power bank. Most power banks will have an indicator light that will let you know when the battery is fully charged.

Use a DC Power Supply

Another way to charge 18650 batteries without a charger is to use a DC power supply. This method requires a bit more equipment than the previous one but can be useful if you don’t have access to a USB port or if you need to charge multiple batteries at once. To use this method, you’ll need an adapter that converts the DC voltage into something that your 18650 battery can use (usually 4.2 volts).

Need Some Alligator Clips or Similar

You’ll also need some alligator clips or similar so that you can connect the positive and negative terminals of the power supply to the corresponding terminals on the battery. Once everything is connected, turn on the power supply and monitor the voltage until it reaches 4.2 volts – at which point, your 18650 battery will be fully charged. If you find yourself in a situation where you need to charge an 18650 battery but don’t have access to any sort of charger, there are still some options available to you.

With a little creativity and some basic electronics knowledge, you can get your 18650 battery charged up and ready for use again in no time!
