The 35W Dual USB-C Port Compact Power Adapter supports up to 35W total output, and it supports Power Delivery 3.0. ChargerLAB has torn apart the Compact version, so we don't yet know what the internal components of the non-compact model look like. The 35W Dual USB-C Port Power Adapter looks similar to a standard MacBook charger, while the 35W Dual USB-C Port Compact Power Adapter is more like an iPad charger with two ports at the bottom rather than at the side. ChargerLAB says that the components on the front and back of the power adapter are symmetrical.Īpple has two versions of the Power Adapter, both priced at $59. The power adapter has a unique design that makes it easy to replace the prongs inside to make it available in different regions, plus it comes with two identical power supply circuits. The host needs to assume that the device will continuously draw up to the offered limit.ChargerLAB, known for taking apart Apple devices and accessories, today shared a teardown of the 35W Dual USB-C Port Compact Power Adapter, giving us a look at the components inside. Offering USB Type-C Current at either 1.5 A or 3.0 A is allowed for a host providing bus power to a device.

The Sink can vary its current draw up to the advertised limit. USB Type-C Current at either 1.5 A or 3.0 A is primarily intended for charging applications.

Default is intended for host operation in providing bus power to a connected device where the host manages the device’s current consumption for the low-power, high- power and suspend states as defined in the USB base specifications.

There is a clear functional distinction between advertising Default versus the USB Type-C Current at either 1.5 A or 3.0 A.

Default is the as-configured for high-power operation current value as defined by a USB Specification (500 mA for USB 2.0 ports 900 mA or 1,500 mA for USB 3.2 ports operating in single-lane or dual-lane, respectively).Three current level advertisements at 5V VBUS are defined by USB Type-C Current: Sadly the standards are not cut and dry as it depends on what the two devices agree to per the Release 2.0 - USB Type-C Cable and August 2019 Connector Specification: Apples spec page for the MacBook Air (M1, 2020) Systems specs Which does not list the USB-C USB4 output power!
