Wall chargers and charging your Galaxy phone or tablet

Samsung Galaxy S21 phone connected to charging adapter

Charging isn't the most exciting aspect of a phone or tablet, but it's a vital one. You can charge your device using any Samsung travel adapter, but charging speeds may vary depending on the charger. Using the charger that originally came with a Galaxy phone or tablet is recommended. If you need additional cables, power adapters, batteries, or replacements, only use Samsung charging devices and batteries.

S21 compatible chargers

We discovered that more and more Galaxy users are reusing accessories they already have. Therefore, we are transitioning to the removal of the wall charger and earphones in our latest line of Galaxy smartphones. If you get a new S21 phone, you will need to buy the wall charger separately. However, the inbox items will still include a USB-C cable that can be used for transferring data or for connecting an existing charger.

Samsung Galaxy S21 phone with compatible chargers

The S21 lineup is compatible with USB-C chargers that support USB Power delivery 3.0, up to 25 watts, or Quick Charge 2.0. Samsung has used the USB-C charger on devices since 2017 – or since the Galaxy S8 and Note8. If you’ve had a Galaxy device since then, you’ll be able to use its charger.

Here are past phones with compatible chargers:

Chargers with Superfast charging

  • Note20 series phones

  • S20 series phones

  • Note10 series phones

  • Z Fold 2

  • Galaxy A71

Chargers with Adaptive fast charging

  • Galaxy Fold, Z Flip, and Z Flip 5G

  • S10 series phones

  • Note9 and Note8 series phones

  • S9 and S8 series phones

  • A70, A50, and A51

If you are a first-time Galaxy customer or do not have the charger for past phones, you can purchase a new wall charger or wireless charger from the Samsung website. Please see the “What kind of charger should I use?” section for more information on different chargers.

Which charger goes with my phone or tablet?

The correct charger is usually included in the box, but if you are in need of a new one, find your model in the following list to see what kind you need. You can purchase replacement chargers directly from Samsung.com.

Most phones and tablets use either a USB Type C or Micro USB charger. USB Type C is the newest type of USB charger. The design helps prevent damage occurring inside the USB port because it doesn't matter which way you insert it into a phone or tablet.

If you aren't sure what model phone or tablet you have, you can check in the device's settings. Navigate to and open Settings, and then tap About phone or About tablet. Your device's name and model number will appear on this page.

Devices that use USB Type C

  • Galaxy Fold phones: Fold and Z Flip

  • Galaxy S phones: S8, S8+, S9, S9+, S10e, S10, S10+, S10 5G, S20 5G, S20+ 5G, S20 Ultra 5G, S21 5G, S21+ 5G, and S21 Ultra 5G

  • Galaxy Note phones: Note8, Note9, Note10, Note10+, Note10+ 5G, Note 20 5G, and Note20 Ultra 5G.

USB Type C charger cable

You're probably already familiar with Micro USB Type B cables. They've been used for a long time with multiple devices. The cable's head is not symmetrical. One side has ridges while the other is flat. Make sure to insert it into your phone's USB port the correct way or it could damage the inside of your phone or tablet.

Devices that use Micro USB Type B

  • Galaxy S phones: S5, S6, S6 edge, S7, and S7 edge

  • Galaxy Note phones: Note5

  • Galaxy A phones: A6

  • Galaxy J phones: J3 and J7 (all models)

  • Galaxy S and E tablets: Tab S, Tab S2, and Tab E

  • Galaxy A tablets: Tab A 10.1 (2016), Tab A 8.0 (2015), Tab A 7.0, and Tab A 9.7.

USB Micro B charger cable

If you've lost your Micro USB Type B charger, you can purchase a new one on Samsung.com. You can also use adapters with these cables to charge USB Type C devices.

What kind of charger should I use?

Important: Using third-party chargers may invalidate your warranty and cause damage.

All phones since the S8 and Note8 (including the new S21!) are compatible with USB-C chargers and QI-certified wireless chargers. Newer Galaxy tablets are also compatible with USB-C chargers but may not work with wireless chargers because of their size.

Wall chargers:

  • Wireless Charger Pad: This wireless pad lays flat on a table, so you can lay your phone down on it to charge. It’s 9W and can be used with other QI-certified devices like iPhones.

  • Wireless Charger Convertible: This is another charging pad, but it stands your phone upright. You can place your phone upright or sideways and use it while it’s charging!

  • Wireless Charger Pad Trio: This new accessory lets you wirelessly charge three devices at once! You can charge a phone, a smart watch, and another device simultaneously. Switch it up for the best order that works for you.

What charger should I use when traveling internationally?

Most Samsung chargers can be used in countries outside of the United States. However, you should check the charger to make sure it's compatible.

"TRAVEL ADAPTER" and an input voltage of 100-240 V will be printed on Samsung chargers. If your charger has these features, then typically only a plug adapter is required when traveling internationally. These can be purchased from many electronics retailers.

Best practices for charging

  • When using wireless charging accessories, please be aware that any metal or magnetic materials (e.g., coins, magnetic cards) placed between the device and the wireless charger may decrease charging efficiency or cause damage to the phone or tablet and charger.

  • Charging may take longer when using adapters, charging wirelessly, or charging the phone or tablet through another device like a PC.
     

  • When using wired charging accessories, always check whether any foreign objects are in the connector or plug, as they may prevent charging or cause the charging accessories to overheat.

  • Make sure your phone or tablet doesn't overheat. Keep it in a cool location, especially while charging.
     

  • Don't let your battery completely drain. With new lithium-ion batteries being used, it is better to keep the battery partially charged, instead of letting it die. When possible, charge your device in small amounts to keep the battery from depleting.
     

    Note: If the power has been depleted, the battery charging indicator may take up to 10 minutes to appear on the phone or tablet's screen while charging.

  • Use a genuine Samsung fast charger for the quickest charge. You can't use the fast charging feature if you're using a standard charger.
     

  • If your phone or tablet is not charging, there are a couple of things that could be causing the problem. However, if your charger doesn't work at all, it should be replaced. If it's under warranty you can request service. If not, you will need to purchase a new one.

Make sure your charger is authentic

Important: Using third-party chargers may invalidate your warranty and cause damage. If you need to replace your charger, visit Samsung.com.

Samsung does not recommend using any chargers other than Samsung chargers, especially chargers that are uncertified or counterfeit. These can hinder the charging of your device and may cause battery issues if used long term.

You should also make sure your charger is an authentic Samsung charger. Standard, genuine Samsung chargers will have the following:

  • The Samsung logo

    Samsung charger's Logo
  • The words "TRAVEL ADAPTER"

    Samsung Travel Adapter words
  • A serial number

    Samsung Travel Adapter's model number
  • A model code

    Samsung Travel Adapter's serial number
