Remove the heat sink, and we can see the internal module. The length of PCB module is 87.6mm (3.45 inches).Īnd the thickness is 23.2mm (0.91 inches). The insulating tape is pasted on the side. It fixed with screws and used to evenly dissipate heat. The large heat sink is covered on the PCB module. The solder joints of AC wire are insulated with heat-shrinkable tubes.
This is the ground wire that is connected to the plug. Use the cutting machine to open the shell.Īnd those black glue is used to fix the module. It supports Apple 2.4A, Samsung 5V2A, DCP, PD3.0 protocolĪnd the supported five fixed PDOs are 5V3A, 9V3A, 15V3A, 20V4.7A, and the 28V 5A additionally.Ĭonnect it to the outlet and use ChargerLAB Power-Z KM001C to test, we can see it can reach 27.73V 4.92A 136.68W. Use ChargerLAB POWER-Z KT002 to test the protocols. The length of the charger is about 96mm (3.78 inches). You can replace the plug equipped with ground wire. You can conveniently change the plug you want to use. It is still equipped with foldable pins and a replaceable plug. And the manufacturer is Flextronics Power.
We will test and teardown this charger to answer those questions.įirstly, it continues the simple white shell of other Apple PD chargers and adopts the glossy surface, and the corners are rounded.īut compared to 81W, 87W and 96W, it changed from the traditional square to rectangle. Many people are curious about the internal design, architecture of the first PD 3.1 GaN fast charger, and what kind of brand new components are inside. You have to use this cable to achieve 140W charging.Įxcept for this 140W PD charger, Apple has released ten PD chargers, from 18W to 140W. There is also a customized USB-C to MagSafe 3 cable. And it’s also the world’s first laptop that supports USB PD3.1 protocol, which makes it can support up to 140W PD fast charging.
MACBOOK USB C CHARGER PRO
The brand new MacBook Pro 16 inch is equipped with powerful processors M1 MAX. So at a minimum, ~50W to supply 45W (which is only enough for a MBAir and not enough for a Pro).On october 19, 2021, Apple held the special event, released AirPMacbook Pro, and also brought a new color for HomePod mini. There does not seem to be a USB-C PD → MagSafe2 option, possibly because it would require a charger that supports enough wattage to both power the MacBook (45W/65W/80W) and the dongle itself. Any USB-C → MagSafe2 dongle would essentially ensure the wattage via USB is available and emulate the correct MagSafe2 charger ID. It won't draw more current than the charger will allow because it knows which charger is plugged in. The MacBook knows what the max wattage for the charger is by getting the id of the charger from the MagSafe2 plug itself. There are only 3 wattages for MagSafe2 chargers and they have well known voltage / currents.
As people have noted, there are plenty of MagSafe2 → USB-C PD options. Electrically, it is possible to go from either direction, it just requires a computer (microprocessor, etc) in between to do the USB-C PD negotiation.
