Most Apple Watches ship without a charger in the box

Apple stopped including chargers with most Apple Watch models starting in 2021. When you open a new Apple Watch, you get the watch itself and a USB-C or magnetic charging cable, but not the power adapter that plugs into the wall. You need to provide your own USB power adapter — the kind you probably already have from a phone, tablet, or laptop.

The only exception is the Apple Watch Ultra, which comes with a USB-C power adapter in the box. Every other current model — Series 9, Series 8, SE, and Ultra 2 — includes only the cable.

This matters because you cannot charge your watch without a wall adapter. The cable alone will not work. You need both pieces: the cable that came with your watch plus a separate USB power adapter.

Key Takeaways

  • Apple Watch Series 9, Series 8, and SE come with a charging cable but no power adapter; the Apple Watch Ultra includes both.
  • You must use a USB power adapter from another device or buy one separately — the cable alone cannot charge your watch.
  • Any standard USB power adapter works, including ones from iPhones, iPads, or Android devices, as long as it matches your watch's cable type.
  • Older Apple Watch models (Series 7 and earlier) used a different magnetic charging cable and may not work with newer adapters.

Which cable type your watch uses

The charging cable that comes with your watch depends on the model and when it was made. Apple Watch Series 9, Ultra, and Ultra 2 use USB-C cables. Apple Watch Series 8 and SE (2nd generation and newer) also use USB-C. If you have an older watch — Series 7, Series 6, SE (1st generation), or earlier — it uses a magnetic charging cable that is not USB-C.

This matters because you cannot use a Series 9 USB-C cable with a Series 7 watch, and you cannot use an old magnetic cable with a new Series 9. The connectors are physically different. Before you buy a replacement cable or adapter, check which series your watch is and what cable type it originally came with.

What power adapters actually work

Any USB power adapter will charge your Apple Watch as long as the cable connector matches. If your watch uses USB-C, you can use the USB-C power adapter from your iPhone 15, iPad, MacBook, or any other device. You can also use a third-party USB-C adapter from Amazon, Best Buy, or another retailer — it does not have to be made by Apple.

The wattage of the adapter does not matter much. Apple Watch charges slowly compared to phones, so a 5-watt adapter (the kind that came with older iPhones) works just as well as a 20-watt or 30-watt adapter. Using a higher-wattage adapter will not damage your watch or charge it faster in any meaningful way.

If your watch uses the older magnetic cable, you need a USB-A to magnetic cable setup. These are harder to find new because Apple phased them out, but you can still buy them from third-party sellers. Do not try to use a USB-C adapter with a magnetic cable — they are not compatible.

Where to buy a charger if you do not have one

If you lost your cable or need a second one, Apple sells replacement cables directly. The USB-C magnetic charging cable costs around $35 on Apple's website. Third-party options are cheaper — you can find USB-C charging cables for Apple Watch on Amazon for $10 to $20, and they work the same way.

For the power adapter, check what you already own first. Most people have a USB-C power adapter somewhere in their house from a phone, tablet, or laptop. If you do not, a basic USB-C power adapter costs $15 to $25 at Best Buy, Target, Walmart, or online. You do not need anything fancy or expensive.

If you have an older Apple Watch with a magnetic cable, replacement cables are harder to find. Check Amazon or eBay for "Apple Watch magnetic charging cable" and the series number. Prices vary widely because these are no longer made by Apple.

How to tell if your charger is working

When you plug in your Apple Watch correctly, you should see a red lightning bolt appear on the screen within a few seconds. This means the watch is charging. If you see nothing, or if the screen stays black, the connection is not working.

First, check that the cable is fully seated in the charging puck on the back of the watch. The magnetic connection should feel snug. If it is loose, the watch will not charge. Second, make sure the power adapter is actually plugged into the wall and turned on — some outlets have switches. Third, try a different power adapter if you have one available, to rule out a bad adapter.

If you still see no lightning bolt after trying these steps, the cable or watch may be damaged. Contact Apple Support or visit an Apple Store to have them test the hardware.

Charging time and battery life

A fully drained Apple Watch takes about 45 minutes to 1.5 hours to charge completely, depending on the model. Series 9 and Ultra charge faster than older models. You do not need to wait for a full charge before wearing the watch — it will work at any battery level above 10 percent.

Most Apple Watches last a full day on a single charge with normal use. If you use features like GPS or always-on display heavily, the battery drains faster. Charging overnight is the most common routine — plug it in before bed, and it will be ready by morning.

If your watch is not holding a charge the way it used to, the battery may be degrading. Apple Watch batteries degrade over time, just like phone batteries. After two or three years of daily use, you might notice the watch needs charging more often. Apple can replace the battery, though it is usually cheaper to upgrade to a newer model.

Frequently Asked Questions

Can I charge my Apple Watch with my iPhone charger?

Yes, if both use USB-C. Most iPhone 15 chargers are USB-C and will work with Series 9, Ultra, or Ultra 2 watches. Older iPhones used Lightning cables, which will not work with any Apple Watch. Check the connector on your iPhone charger before assuming it will work.

What if I lost the cable that came with my watch?

Buy a replacement USB-C magnetic charging cable from Apple or a third-party seller like Amazon. Make sure you order the right type for your watch model — USB-C for newer watches, or the older magnetic cable for Series 7 and earlier. The cable alone costs $10 to $35 depending on the brand.

Do I need to buy an Apple charger or can I use any brand?

Any brand works as long as the connector matches your watch's cable type. Third-party USB-C cables and adapters are cheaper and perform identically. You do not need to buy from Apple unless you want to.

Can I charge my Apple Watch with a wireless charger?

No. Apple Watch does not support wireless charging pads like Qi chargers. You must use the magnetic charging cable that came with your watch or a compatible replacement cable plugged into a power adapter.

Why does my watch charge so slowly?

Apple Watch is designed to charge slowly compared to phones — this is normal and protects the battery. If it is taking much longer than usual (more than 2 hours for a full charge), try a different power adapter or cable. A damaged cable or weak adapter will charge the watch very slowly.
