While it isn't for sale yet, Apple has revealed the new MagSafe Duo charger's price. At $169, it is significantly pricier than the standard MagSafe charger, which costs $55. As its name suggests, it can charge compatible iPhones, AirPods wireless charging case, other Qi-certified devices, and the Apple Watch, which the standard MagSafe Charger doesn't support. It's foldable, so it's easy to bring around as well.
Unfortunately, it will cost you more if you need a power adapter to plug it into an outlet. Apple doesn't include it with the charger. You can buy Apple's 20W USB-C power adapter for $25.
