The USB-C port and the built-in cable share the same protocol compatibility.

The USB-C port and integrated cable share identical fast-charging protocol support.

Using the USB-C interface for wired fast charging of the iPhone, the actual charging power reached 19.23W, successfully establishing a PD fast charging connection.

Having looked over the product's design and compatibility, let's moving on to the teardown.

Teardown

Removing the rear panel reveals an efficient internal layout, the massive battery cells take up most of the space, while the mainboard is neatly tucked away at the top edge.

A large black graphite thermal pad lines the back panel, which uniformly dissipates heat from the battery cells and the PCBA.

The surface of the battery cell is covered with high-temperature tape for protection, and a long strip of blue thermal pad is attached to the PCBA to assist in heat dissipation.

The PCBA is layered with a blue thermal conductive pad, which ensures that heat from the mainboard's core components is quickly transferred to the external housing.

Components are clearly visible once the thermal interface material is removed, and the battery leads are hard-soldered to the PCBA.

An NTC thermistor probe is fixed to the side of the battery with high-temperature tape to monitor the cell temperature in real time and ensure charging and discharging safety.

With the battery pulled from the housing, we can confirm the cell is manufactured by Tuoyuan. It’s good to see the 3C and CE safety certification, other info is rather blurry and difficult to identify.

The PCBA is laid out with precision. Moving from left to right, you'll encounter the display ribbon cable and the integrated cable's terminals, followed by the battery leads, the NTC thermistor contact, and the wireless charging coil assembly on the far right.

As shown in the image, the cable channel is perfectly integrated into the side of the housing.

Separating the internal chassis, the wireless charging module, the PCBA, and the display panel.

The front panel housing has a ring of strong magnets and a positioning magnet in the middle, providing magnetic positioning for the iPhone.

The wireless charging transmitter coil uses multiple strands of Litz wire tightly wound on a magnetic shielding sheet, with a circular magnet in the center, specifically designed for Apple Watch positioning and charging.

The front of the PCBA features the USB-C interface, power choke, power button, filtering caps, the master control chip, and the dedicated wireless charging transmitter chips, including the power stage drivers.

The back of the PCBA features the lithium battery protection chip, the display driver MCU, and the NOR Flash.

Here is the elongated display module we've isolated from the main unit.

The master control chip is from iSmartWare, model SW6236. This high-integration SOC is designed for multi-port power banks (2USB-A and 2USB-C), featuring a high-efficiency 5A switching charger and a 22.5W synchronous boost converter, achieving an impressive conversion efficiency of up to 95.73%. Furthermore, it maintains an ultra-low standby power consumption of less than 40μA at 3.7V.

It supports fast charging on all four ports, with the two USB-C ports facilitating bidirectional input and output. It is compatible with a wide array of mainstream fast-charging protocols, including PPS, PD, SCP, FCP, QC, AFC, PE, and BC1.2, ensuring universal compatibility for most market-leading devices.

The SOC offers versatile battery chemistry support, including 3.6V/3.65V LiFePO4 and various ternary lithium battery voltages (4.2V to 4.5V). Through its I²C interface, developers can precisely configure charging currents, output voltages, and current limits. Additionally, the chip supports smart insertion detection, low-current mode, and wireless charging mode, including the capability for simultaneous fast-charged input and wireless output.

iSmartWare has packed a lot of "smarts" into the SW6236. Its built-in Coulomb counter and 12-bit ADC deliver pinpoint battery accuracy, allowing for versatile display options like simple LEDs or an advanced "188" numeric display that even includes icons for wireless charging status.

Beyond display functionality, it is equipped with a comprehensive suite of safety protections—including OVP, OCP, UVP, OTP, CTP, and NTC-based temperature monitoring—guaranteeing operational reliability and device longevity.

A VBUS MOSFET, marked 8205A.

Another one, also marked 8206A.

The wireless charging master control chip, marked R9337xDQ.

The wireless charging power stage is from SouthChip, model SC5008. This highly integrated 15W full-bridge power stage controller is engineered to meet the rigorous WPC standards.

It encompasses all essential analog components required for WPC-compliant wireless power transmission, including low-resistance MOSFETs, high-efficiency gate drivers, internal 5V and 3.3V LDOs, precise communication demodulators, and integrated input current sensing circuitry.

Designed to work in tandem with the primary transmitter controller, it facilitates a robust, cost-effective architecture compliant with both WPC V1.3.2 Baseline and Extended Power Profiles.

The SC5008 enhances system safety and reliability through advanced Foreign Object Detection (FOD). It achieves this by continuously monitoring transmitted power and comparing it against the power received, utilizing a high-precision integrated current sense amplifier to measure the input DC current accurately, and the device integrates 5V and 3.3V LDOs to power both internal and auxiliary external circuitry.

Its robust protection suite—including UVLO, OCP, SCP, and OTP—ensures stability under varied operating conditions. It is housed in a compact 3mm x 4mm QFN package.

This is an NTC thermistor, utilized for OTP.

The MCU is from XHSC, model HC32L021. It features a 48MHz ARM Cortex-M0 core and is housed in a QFN20 package, and is used for screen display driving and related logic control.

Next to the MCU is a SPI Flash memory chip from BoyaMicro, model 25Q16AWTIG , which is used to store firmware and screen UI information.

A MOSFET, marked 8205A, is used for power supply switching control.

The two lithium battery protection chips are from iCM, model CM1143-BBS, and are packaged in SSOP-3.

These chips incorporate high-precision voltage detection and delay circuits. By detecting the battery's voltage and current, they provide protection against overcharging, over-discharging, and overcurrent. They are suitable for protection circuits of single-cell lithium-ion/lithium polymer rechargeable batteries.

Here is the info about ICM CM1143-BBS.

The wireless charging resonant cap MOSFET, marked R4885.

Well, those are all components of the inno3C 22.5W Magnetic Wireless Power Bank.
