How to Charge a Fitbit Without a Charger?

Fitbit has revolutionized the way we monitor our health and track our fitness goals. With a wealth of features from heart rate monitoring to sleep tracking, it’s no wonder that these devices have become integral parts of our daily routines. However, there may be instances when you find yourself without a Fitbit charger, leaving you with a device that’s steadily running out of battery power.

Fortunately, charging a Fitbit doesn’t always require its specific charger. With some everyday gadgets, it’s possible to infuse life back into your Fitbit. By using certain materials like USB cables, power banks, computers, or even other Fitbit chargers, you can easily navigate around this issue.

This article delves into the various methods you can use to charge your Fitbit without its charger. Not only will you learn about the techniques and materials you need, but you’ll also gain insights into the precautions and estimated charging times of these methods.

What Is a Fitbit and How Does It Usually Charge?

Fitbit is a popular brand of wearable technology, known for its range of fitness trackers and smartwatches. These devices monitor a range of health metrics such as step counts, heart rate, and sleep quality, supporting users in their fitness and wellness goals.

Typically, a Fitbit device charges using its proprietary charger that comes with the device at the time of purchase. This charger has a specific design and mechanism that matches the charging port on the device. It usually connects to a power source like a laptop or power adapter via a USB cable, enabling Fitbit to recharge.

Why Might You Need to Charge a Fitbit Without a Charger?

There are several circumstances where you might need to charge a Fitbit without its charger. Maybe you’ve lost or misplaced the charger, or it could be damaged and unusable. Other times, you may be traveling and forget to pack it. No matter the situation, finding yourself with a dying Fitbit and no charger can be frustrating.

What Do You Need to Charge a Fitbit Without a Charger?

Charging a Fitbit without its charger requires some common materials. These might include:

  1. A USB cable, preferably one with a narrow plug.
  2. A power source, such as a computer, a power bank, or a wall charger with a USB port.
  3. (Optional) A different Fitbit charger, if available.

These materials work as substitutes because most Fitbit devices can be charged with a simple power connection through their charging ports, and do not strictly require a specific charger.

How Can You Charge a Fitbit With a Computer or Laptop?

You can use a computer or laptop as a power source to charge your Fitbit. Here’s a step-by-step guide:

  1. Plug one end of the USB cable into the charging port of your Fitbit device.
  2. Connect the other end of the USB cable to a USB port on your computer or laptop.
  3. Ensure the computer or laptop is turned on so it can provide power for charging.

Can a Power Bank Be Used to Charge a Fitbit?

A power bank can also be a handy solution to charge a Fitbit without its charger. The process is similar to charging it with a computer or laptop:

  1. Connect your Fitbit to the power bank using the USB cable.
  2. Turn on the power bank.
  3. Monitor the device to ensure it’s charging.

While convenient and portable, power banks may not always provide the same power output as a wall charger, which might result in slower charging times.

Can a Smartphone Charger be Used to Charge a Fitbit?

Yes, in most cases, a smartphone charger can be utilized to power your Fitbit. However, it’s important to note that not all smartphone chargers are compatible with Fitbits. Here’s how to do it:

  1. Identifying a Compatible Charger: Ensure the charger has a USB port and delivers an appropriate power output for your Fitbit device.
  2. Connecting Your Fitbit: Use your USB cable to connect your Fitbit to the smartphone charger.
  3. Initiating Charging: Plug the smartphone charger into a wall outlet. Check your Fitbit screen to confirm it’s charging.

Remember to exercise caution when using this method. Charging your Fitbit with a high-power charger could potentially harm the device.

How to Charge a Fitbit With a Different Fitbit Charger

Fitbit has several models, each with its own specific charger. However, in some instances, one Fitbit charger can be used to charge a different Fitbit model. To do this:

  1. Compatibility Check: Ensure the charger fits into the charging port of your Fitbit model.
  2. Start Charging: Connect your Fitbit to the charger, then plug the charger into a power source like a computer or wall outlet.

Remember, while this method can be a convenient solution, frequent use could potentially cause damage to the charging port over time due to the design differences between chargers.

How Long Does It Take to Charge a Fitbit Without a Charger?

Charging times can vary depending on the method used. Generally, charging a Fitbit with a computer, power bank, or alternative Fitbit charger can take up to two to three hours for a full charge. Using a smartphone charger might speed up the process, but you need to ensure the charger isn’t too powerful for your Fitbit to handle.

Precautions When Charging a Fitbit Without a Charger

When charging a Fitbit without its designated charger, here are some safety precautions to consider:

  1. Power Output: Check the power output of your alternative charging method. High-powered chargers could potentially damage your Fitbit’s battery.
  2. Connector Compatibility: Ensure the USB cable fits perfectly into your Fitbit’s charging port. A loose connection can damage the port or lead to ineffective charging.
  3. Device Supervision: Keep an eye on your Fitbit while it’s charging, especially if you’re using an alternative method. This helps prevent potential overheating or other issues.

Frequently Asked Questions (FAQs)

Does charging a Fitbit with an alternative method harm the device?

Not necessarily. However, it’s important to ensure the power output is compatible and the connection is secure. Using incompatible chargers or forcing connections could potentially harm the device.

How can I extend the battery life of my Fitbit?

Reducing screen brightness, turning off all-day sync, and disabling notifications can help extend the battery life of your Fitbit.

Can I charge my Fitbit overnight using an alternative charging method?

While it’s possible, it’s best to monitor your Fitbit while charging with an alternative method, as these methods may pose a risk of overheating or overcharging.


Though it can be inconvenient to find yourself without a Fitbit charger, there are alternative methods to power your device. By using items like a USB cable, a laptop, or even another Fitbit charger, you can keep your Fitbit charged and continue tracking your fitness journey. Just remember to keep safety first, making sure your alternative charging methods are compatible with your Fitbit to prevent potential damage.
