The USB-C port is compatible with the same protocols as the integrated USB-C cable.

The PDO communication is also the same.

The USB-A port supports QC3.0, FCP, SCP, and DCP charging protocols.

When charging the HONOR Magic7 RSR using the integrated USB-C cable, the charging power is about 64.62W.

Teardown

Next, let's take it apart to see its internal components and structure.

The snap-fit enclosure is opened by disengaging the clips.

The battery cells are covered with protective foam padding.

A thermistor is installed at the front of the battery cells, and the PCB is secured with screws.

Remove the PCB and battery cells. The bottom of the PCB features a black plastic plate and supporting posts.

The battery pack is connected to the front lithium battery protection PCB via nickel strips.

The front of the lithium battery protection PCB houses the battery protection chip, battery protection MOSFETs, and the balancing circuitry.

The battery pack consists of four identical polymer lithium cells.

The cells are from FHE, model FHPS576477P, with a nominal voltage of 3.87V, a capacity of 5,000mAh, and an energy of 19.35Wh. They are CCC-certified.

The back of the PCB has no components.

The battery protection chip is from iCM, model CM1341-QAT, specifically designed for 4-series lithium-ion or LiFePO₄ batteries. It features built-in high-precision voltage and current detection circuits.

By monitoring the voltage of each cell, charge and discharge currents, and temperature, the chip provides protections including overcharge, over-discharge, cell balancing, open-circuit detection, low-voltage charge inhibition, over-discharge current, short-circuit, overcharge current, and over-temperature. The discharge overcurrent protection delay is adjustable via an external capacitor, while other protection delays are built-in.

The battery protection MOSFETs are from TUOFENG, model TF040N03N, NMOS type, with a voltage rating of 30V and an on-resistance of 4.7 mΩ. They are packaged in PDFNWB5×6-8L.

The front of the PCBA module features a synchronous buck-boost controller, a synchronous buck-boost MOSFET, a buck-boost inductor, solid capacitors, and other components.

The back of the PCBA houses the protocol chip, synchronous buck-boost MOSFETs, and VBUS MOSFETs.

The synchronous buck-boost controller is from SouthChip, model SC1815A, and comes in a QFN32 package.

The synchronous buck-boost MOSFETs are from TUOFENG, model TF030N03NG, NMOS type, with a voltage rating of 30V and an on-resistance of 3.6 mΩ. They use a PDFNWB5×6-8L package.

The fourth TUOFENG TF030N03NG synchronous buck-boost MOSFET is located on the front side of the module.

The buck-boost inductor is reinforced with adhesive.

The solid capacitor is from YMIN, rated at 25V 220 μF.

There is another capacitor with the same specifications.

The protocol chip is a SouthChip SC2006A, a fast-charging controller supporting three Type-C DRP ports. It is compatible with all mainstream fast-charging protocols and features CC and DPDM interfaces. Its target applications include power banks, car chargers, and power tools.

The SC2006A integrates Type-C/PD circuits, DPDM/UFCS protocol circuits, a VBUS discharge path, voltage and current sensing, an 11-bit high-performance ADC, two 11-bit DACs, NMOS gate drivers, an I²C interface, and protection circuits, minimizing the need for external components.

The SC2006A features a built-in 32-bit high-performance microcontroller with 128 KB of flash memory and 8 KB of SRAM, providing a cost-effective solution for various applications. It also supports multiple protection mechanisms, including overvoltage, undervoltage, overcurrent, short-circuit, overtemperature, DPDM overvoltage, CC overvoltage, and VCONN overvoltage/overcurrent/short-circuit protection, ensuring stable and reliable system operation.

The VBUS MOSFETs for the integrated USB-C cable are from TUOFENG, model TF030N03M, NMOS type, with a voltage rating of 30 V and an on-resistance of 3 mΩ, packaged in PDFN3333‑8L.

The VBUS MOSFETs for the USB-C port also use the TUOFENG TF030N03M.

The VBUS MOSFETs for the USB-A port also use the TUOFENG TF030N03M.

Well, those are all components of the HONOR CHOICE 100W 20000mAh Power Bank.

Summary of ChargerLAB

Here is the component list of the HONOR CHOICE 100W 20000mAh Power Bank for your convenience.

It features an integrated USB-C cable, along with one USB-C and one USB-A port, supporting up to 100W PD/SCP fast charging. A low-current mode is designed for small devices such as wearables, ensuring safe low-power output without damaging the device.

After taking it apart, we found that it uses FHE polymer cells and an iCM CM1341-QAT lithium battery protection solution. The module employs a SouthChip SC1815A power management chip paired with the SC2006A protocol chip to control the integrated USB-C cable, one USB-A port, and one USB-C port for input/output. The battery protection MOSFETs, synchronous buck-boost MOSFETs, and VBUS MOSFETs all come from TUOFENG. Key components, including chips and capacitors, are secured with adhesive for protection.
