You don’t need the original charger to power up your watch

What to Know

  • Samsung Galaxy Watches charge wirelessly using the Qi wireless charging standard. 
  • If you don't have its charger, place the Galaxy Watch on any compatible Qi charging station or a Galaxy Phone that supports PowerShare. 
  • Not all Qi chargers work with Galaxy Watches, and you need to monitor for excess heat when using a third-party charger.

This article explains how to charge a Samsung Galaxy Watch without the charger.

Can I Charge My Samsung Watch With Any Wireless Charger?

You can charge your Samsung watch without the charger it came with, but you can’t charge it without any charger at all, and you specifically need a wireless charger. The Samsung Galaxy Watch series relies on Qi wireless charging, which means the watches lack physical charging ports. There’s no way to connect a USB charger or any other kind of charger, so wireless charging is the only option.

Not all wireless chargers work with Samsung watches, and it's essential to monitor for excess heat when using a third-party charger. The Galaxy Watch 4, in particular, is only guaranteed to work with the Galaxy Watch 4 charger and the Samsung Duo, but some third-party WPC-compliant Qi chargers do work.

If you've lost or misplaced your Galaxy Watch charger, or you're traveling and forgot it at home, you have two options:

  • Use a compatible Qi charging station: Galaxy watches use the Qi wireless charging standard, which means you can charge them with any compatible Qi charging pad or station. Third-party chargers aren't guaranteed to work, though, even if they use the Qi standard.
  • Use a Galaxy phone that supports PowerShare: If you have a Galaxy phone that supports PowerShare, you can charge your Galaxy Watch wirelessly using the phone.

Some phones from other manufacturers are also capable of wireless power-sharing. Still, it's vital to monitor excess heat if you use a non-Samsung phone to charge a Galaxy Watch.

How Can I Charge My Samsung Watch Without a Charger?

There’s no way to charge a Samsung watch without a charger, but you can use most wireless chargers if you don’t have access to the charger that came with your phone. Samsung watches use the Qi standard so that you can charge a Samsung watch on any compatible Qi charger. Some Qi chargers work better than others, though, so it’s a good idea to look for a wireless charging pad or station designed for watches.

If you can’t get your Samsung watch to charge on your wireless charger, and repositioning doesn’t help, the coils in the charger probably aren’t capable of charging the ones in your watch. If you notice excess heat when using a third-party charger, remove it immediately.

Here’s how to charge your Samsung watch without the original charger:

  1. Obtain a Qi wireless charger.

    Not all Qi wireless chargers will work. Stick to reputable brands, as some wireless chargers are technically Qi-compatible but don’t work with the small coils used in watches. Check if the manufacturer specifies that it works with Samsung watches, and look at the reviews to see if people have used it with your specific watch.

  2. Place your watch on the charger.

  3. Reposition the watch as necessary until it starts charging.

  4. If necessary, remove the watch band. The watch band may cause the watch to sit too far away from the surface of the charger.

How Do I Charge My Samsung Watch With My Phone?

Many phones support Qi wireless charging to receive power from a charging station, but a few are capable of also reversing that process to charge other devices. Samsung's PowerShare feature available in some Galaxy phones allows you to charge devices from your phone, and it's meant to work with Galaxy watches. If your phone has this feature, you can charge your Samsung watch without the charger.

Samsung’s PowerShare is designed to work with Galaxy Watches, but the power-sharing feature of other phones may work as well. If you have a non-Samsung phone with a similar feature, monitor your phone and the watch for excess heat, and remove the watch if it gets hot.


Here’s how to charge your Galaxy Watch with your Galaxy Phone:

  1. Charge your phone to at least 30 percent.

  2. Swipe down on the screen to open the quick settings.

  3. Tap Wireless PowerShare.

  4. Place your phone face-down on a flat surface.

  5. Place your watch on the back of the phone.

  6. Rotate and reposition the watch until it starts charging.
