How to charge your Apple Watch as fast as possible

Fast charging is one of the most practical improvements to recent Apple Watch models. With the right cable and adapter, you can go from 0 to 80% in just 30 to 45 minutes, depending on your device. But Apple doesn’t give you everything you need in the box, and not all models are compatible. Here’s how to unlock the fastest charge times possible.

Which Apple Watch models support fast charging

Apple’s fast charging is available on several models, including Apple Watch Series 7, 8, 9, 10, Ultra, and Ultra 2. The latest Series 10 charges the fastest—up to 80% in only 30 minutes. Older compatible models take around 45 minutes, while the Ultra models reach that level in roughly an hour. If you’re using a Series 6 or older, fast charging is not supported regardless of accessories.

What accessories you need to charge faster

To access fast charging, you’ll need Apple’s USB-C Magnetic Fast Charging Cable (model A2515). This cable has an aluminum housing around the puck and is bundled with new compatible models, but you can also purchase it separately. Beware of third-party cables that don’t support the same power delivery specs.

Next, you need a USB-C wall adapter that supports at least 5W USB Power Delivery. Apple’s 18W, 20W, or higher adapters work, and trusted third-party brands like Anker also offer reliable options. Note: the MagSafe Duo and Apple Watch Magnetic Charging Dock do not support fast charging, no matter what cable or adapter you use.

For best results, pair the A2515 cable with a certified 20W USB-C adapter and avoid using outdated docks or underpowered bricks.
