The new Apple Watch Series 12 and Apple Watch Ultra 4 have hardware changes that allow for faster charging, but you will need to use the new version of the Apple Watch Magnetic Fast Charger included in the box in order to achieve this boost. If you need extra ones for your own charging stands or travel or so forth, Apple released the new version of the charger on its online store last week, with U.S. pricing set at $29.
We have confirmed that the new version of the Apple Watch charging puck — model A3277 — can deliver up to 10W of power to enable the faster charging speeds. The previous version of the charger is limited to 5W. Accordingly, you will also need to use a USB-C Power Delivery charger that is rated 10W or higher for the fastest charging.
With just 15 minutes of charging, Apple said the new charger can add 12 hours of battery life to the Series 12 and 18 hours of battery life to the Ultra 4.
The previous Apple Watch Series 11 and Apple Watch Ultra 3 can get 8 hours and 12 hours of battery life respectively with a 15-minute charge, according to Apple. Using the new charging puck will not speed up these times, as the Series 12 and Ultra 4 have hardware changes, so you need both a new watch and the new charger for the fastest charging.
| Model | New Charger | Previous Charger |
|---|---|---|
| Apple Watch Series 12 | 12 hours of battery life in 15 minutes | 8 hours of battery life in 15 minutes |
| Apple Watch Ultra 4 | 18 hours of battery life in 15 minutes | 12 hours of battery life in 15 minutes |
| Apple Watch Series 11 | 8 hours of battery life in 15 minutes | 8 hours of battery life in 15 minutes |
| Apple Watch Ultra 3 | 12 hours of battery life in 15 minutes | 12 hours of battery life in 15 minutes |
As mentioned, the new 1-meter Apple Watch Magnetic Fast Charger to USB-C Cable is available to order for $29 U.S. on Apple's online store.
