The new Apple Watch Series 12 and Apple Watch Ultra 4 feature hardware changes that allow for faster charging, but you’ll need to use the new version of the Apple Watch Magnetic Fast Charger included in the box to get that boost. If you need more for your own charging stands or for traveling etc., Apple released the new version of the charger on its online store last week, with the US price 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 faster charging speeds. The previous version of the charger is limited to 5W. Therefore, you will also need to use a USB-C Power Delivery charger rated at 10W or more 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, from a 15-minute charge, according to Apple. Using the new charging puck won’t 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 faster 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 to USB-C Magnetic Fast Charger Cable is available to order for US$29 from Apple’s online store.
