About this item

Product details

Apple's current brick, launched alongside the iPhone 17 line, which ships with no charger in the box. It holds 40W steadily and briefly steps up to 60W when a device asks for it, so a phone takes on the bulk of its charge early and then settles.

The single USB-C port also suits an iPad, an Apple Watch puck or AirPods, stepping down to whatever they draw. Prongs fold flat against the housing, and a MagSafe puck plugged into it reaches its full 25W.

Sold and shipped by ComBuy. Free shipping on orders over $35.

Key features

Holds 40W continuously and peaks at 60W when the device requests more
Charges iPhone 17 to about 50 percent in 20 minutes over a USB-C cable
Uses USB Power Delivery 3.2 with adjustable voltage for cooler, steadier output
Single USB-C port also suits iPad, Apple Watch pucks and AirPods cases

Foldable prongs keep the brick flat in a bag or jacket pocket

Questions & answers

Is a cable included?

No, the adapter is sold on its own. You need a USB-C to USB-C cable for an iPhone 15 or later, an iPad or a Mac, or USB-C to Lightning for an older iPhone.

What does dynamic power actually mean?

It runs at 40W as its normal ceiling but will lift briefly to 60W when a device pulls hard, then drop back. The voltage is also trimmed in fine steps, which keeps the brick and the phone cooler.

Which devices can I charge with it?

Any USB-C device: iPhone, iPad, AirPods, an Apple Watch charging puck, and a MagSafe puck, which needs 30W or more behind it to hit 25W. It will also trickle a MacBook Air.

Is it enough for a MacBook Air?

It will charge one, more slowly than the brick Apple ships with the laptop. Fine overnight or during light work, less suited to heavy exporting while plugged in.

Can I use it on 220V power abroad?

Yes, the input range covers 100-240V. The prongs are US shaped, so a physical plug adapter is still needed for other outlet types.
