Here are a few simple techniques for charging your Fitbit without a charger.

1. Charge a Fitbit Using USB Port on Laptop

If you don’t have your Fitbit charger with you, you can charge it using a USB port on your computer or laptop. Simply use a USB cord to connect your watch to the laptop to start charging.

It is, without a doubt, the most common and simplest method of charging your Fitbit without a charger.

Important: If the port to which you attached the cable doesn’t appear to be charging your Fitbit, try another port.

2. Charge the Fitbit to a Wall Charger

If you don’t have the official Fitbit charger, you can use any USB wall charger, such as the one from your phone or tablet, to recharge your Fitbit. This method may charge it considerably faster and more effectively than plugging your Fitbit into a laptop or desktop computer.

Further, it is recommended to use a UL-certified USB wall charger. It will not harm the battery or the device, so you may leave it charging for as long as you want.

3. Charge Your Fitbit from Power Bank

A power bank is one of the affordable ways to recharge your Fitbit. It can be used as an external charger when you don’t have a charger for your Fitbit watch. In addition, they are especially useful when traveling because you can charge your devices while on the go.

Charging your Fitbit with a power bank is easy if you follow these simple instructions.

Step 1: First, ensure your power bank is fully charged and able to send voltage to your Fitbit.

Step 2: Turn on the power bank by pressing the power button. When the light comes on, the device is ready for usage.

Step 3: Connect the charging wire to your power bank and Fitbit smartwatch.

Step 4: Examine the watch’s battery life.

Step 5: Once your power bank has finished charging, press the power button to turn it off.

Wireless power banks are also available for your convenience. When using a wireless power bank to charge your Fitbit, you should align the backside of your watch with the rear of the power bank. Make sure the two devices are positioned parallel to the charging coil.

4. Charge Your Watch with a DIY Fitbit Charger

Here’s how to make your own Fitbit wall charger:

Step 1: Using a nail clipper, carefully cut the USB’s smaller end off.

Step 2: Next, peel away the outer insulation from the end you just cut.

Step 3: Cut all wires apart from the red and black ones.

Step 4: Remove the insulation from the red and black wires and coil them tightly.

Step 5: Attach the black cable to the Fitbit’s side button. You can use tape for this.

Remember that the connection above is very weak and hard to keep in place. So, if you want to see how much your Fitbit has charged, utilize the app on your smartphone. It is preferable not to interfere with the setup by touching or moving it.

Step 6: Connect the USB’s other end to a power bank.

Caution: Do not use a laptop or a wall adapter for this procedure since a short circuit may occur if you accidentally contact the connections at the end. Ultimately, it can harm the laptop’s battery.

How to Check If the Fitbit Watch is Charging

When your Fitbit watch is charging, you can check the battery level by pressing the button or tapping the screen. Fitbit series such as Inspire, Alta, Ace, and Charge will display a solid battery icon on the screen when the device is fully charged to 100%.

In some Fitbit devices like Flyer and Flex, you can check the watch’s charging status with the LED light at the watch’s back. The device may flash various colored lights to indicate the charging status, as given in the following table:

LED ColorBattery Status
White LightMedium to fully charged

Essential Tips for Charging Your Fitbit


Here are some important tips that will enable you to charge your Fitbit watch and increase its lifespan properly:

1. Use the Original Charger

Whenever possible, charge your Fitbit smartwatch using the original charger that came with it. Use a charger designed for your battery model to avoid harming the battery.

2. Let The Battery Drain Before Charging.

If you always charge your smartwatch before the battery is entirely depleted, the battery will never be able to calibrate itself. Let the battery completely discharge once in a while before recharging it.

3. Keep The Charging Port Clean.

A buildup of dirt and debris in the charging port can hinder the charger from forming a proper connection. The charging port should be cleaned with a toothpick or sharp item at least once a month.

4. Avoid Extreme Temperatures

Ensure you do not leave your smartwatch in a hot car or direct sunlight for long periods. In doing so, the battery is at risk of being damaged and its lifespan reduced.

5. Avoid Using Heavy Apps and Games

High-resolution graphics and animations can quickly deplete the battery life of an app or game. Avoid using these applications and games if you want to extend the battery life of your Fitbit smartwatch.

By following these suggestions, you may prolong the battery life of your Fitbit and ensure that it charges properly.


If you don’t have a charger, there are numerous ways to charge your Fitbit. You can use a computer, a power bank, or an external charger. These ways are fantastic for quick charging, so you may pick whichever one you like best.

The most important thing is that you follow the directions precisely so your watch is charged properly.
