Teardown

Peel off the base's anti-slip silicone pad to expose the four hidden Phillips screws.

After unscrewing the base and opening the cover, the interior is dominated by a large metal plate, with an LED PCB connected to one side.

Here is the LED PCB, featuring a light guide cover for even light distribution.

Removing the metal bottom plate reveals the wireless charging coil used for the AirPods.

This is the mainboard, we can see that components like the chokes on the PCBA are reinforced with white potting compound.

Moving on to the MFM front panel, the module is tightly coupled with the heatsink to boost thermal performance and keep excess heat away from the phone.

With the MFM and PCBA taken out, we can see the solder joints for the MFM and MFW wireless charging modules are clean and well-soldered.

Removing the PCBA reveals a small power input PCB positioned on the side.

The USB-C female port is soldered onto the edge of a separate extension PCB.

There are no other components on the back of the mainboard but the step-down chokes.

A pink thermal pad is applied to the back of the MFM, contacting the internal heatsink for better thermal management.

The large metal heatsink base extracted from the housing is specifically designed to pull heat away from the MFM and dissipate it.

We have extracted the original Apple MFM-certified MagSafe charging module, which is connected using soldered wires.

The wireless charging module for the phone is an Apple-certified MFM MagSafe component.

Removing the MFW wireless charging arm, which extends from the main unit.

With the white cover removed, we can see the official MFW-certified Apple Watch wireless charging module located beneath.

On the front of the PCBA, the top three chokes manage the MFM and MFW wireless charging, while the bottom choke powers the earphone wireless charging alongside the main controller.

The synchronous buck-boost chip is from Southchip, model SC8724, housed in a QFN25 package. It is a four-switch synchronous buck-boost converter that ensures high power efficiency and stable voltage regulation, regardless of whether the output voltage is higher, lower, or equal to the input voltage.

It supports an input voltage range of 2.7V to 22V, an output voltage range of 3V to 22V, and provides a maximum output current of 3.5A.

The SC8724 uses average current mode control, with output voltage set by resistors on the FB pin. External settings allow for adjustments to both the switching frequency and the operating mode (PSM/FPWM).

It also supports programmable output current limiting to suit different needs. Safety is ensured by a suite of protections, including internal current limiting, input UVP, output OVP, output/FB short-circuit protection, and OTP.

The chip is from MPS, model MP1471A, marked IAGCS, and in a TSOT23-6 package. It is a high-frequency, synchronous, rectified, step-down, switch-mode converter with integrated power MOSFETs.

It delivers 3A of continuous output current over a wide input supply range, providing a highly compact solution with excellent load and line regulation.

Well, those are all components of the Anker737 MagGo 3-in-1 wireless charger.

Summary of ChargerLAB

Our teardown of the Anker737 MagGo 3-in-1 wireless charger showcases its standout industrial design, featuring a unibody curved panel and a unique triangular skeleton structure. An embedded metal plate in the base provides the necessary weight for stable, one-handed device retrieval.

Inside, Anker has opted for official Apple MFM and MFW modules for phone and watch charging, ensuring seamless compatibility. Power for these modules is provided by Southchip's SC8724 and an MPS MP1471A.

The earphone charging module utilizes an MPS MP1471A synchronous step-down chip paired with a CVS CV90362A master control chip. The power stage is driven by a dual Vergiga VS3622DB NMOS MOSFETs, alongside a JSCJ CJAB55P03A PMOS for switching control.

Thermal design is equally thorough, with grid-pattern vents in the housing and thermal potting on critical components. The MFM module is coupled to a large metal heatsink base via thermal pads for effective cooling. It is, in short, a premium, well-engineered desktop charging solution with a unique aesthetic.
