Apple 40W USB C Dynamic Power Adapter with 60W Max A3353 - MGTV4B/A

Apple brings a more compact approach to higher-output charging with the 40W Dynamic Power Adapter, a USB-C power adapter that combines a pocket-sized format with advanced power delivery. The A3353 model provides a sustained 40W output and can boost up to 60W in short bursts, offering higher power when required while remaining close in size to Apple’s standard 20W charger.

Built for USB Power Delivery 3.2 with Adjustable Voltage Supply (AVS), it can negotiate the voltage required by compatible devices rather than relying only on fixed levels. Foldable UK 3-pin prongs make it easier to carry, while internal thermistors monitor temperature in real time and adjust output to keep charging within safe operating limits. It is optimised for iPhone 17 and iPhone Air, and remains compatible with USB-C enabled devices including iPads, older iPhones and MacBook Air models.
