That's how big it is in the hand.
ChargerLAB POWER-Z KM003C shows the USB-C port can support DCP, SAM 2A, and Apple 2.4A charging protocols.
Teardown
Next, let's take it apart to see its internal components and structure.
First, pry along the gap to open the cover.
Separate the magnetic panel and casing.
The battery pack is fixed on the aluminum alloy casing.
The inside of the button is fixed with double-sided tape.
The position contacting the PCBA module is insulated with transparent tape.
The battery is protected by foam cushioning around it.
There are battery tabs and a thermistor on the top of the battery.
Remove the battery from the housing.
The battery cell model is 606072, from GFL, with a nominal voltage of 3.87V, a nominal capacity of 5000mAh, and an energy of 19.35Wh.
The NTC thermistor is used to detect battery temperature.
The coil is connected to the PCBA module through wires.
The wires are fixed tightly with high-temperature tape.
The PCBA module is fixed with screws.
The cell tabs and PCBA module are connected by spot welding.
The coil is insulated with highland barley paper.
Remove the barley paper.
There is also a thermistor inside the coil, embedded in the middle of the magnetic isolation sheet.
Separate and remove the coil, PCBA module, etc. from the housing.
The magnet ring adopts a double-layer integrated structure.
This is the wireless charging coil.
The NTC thermistor is used for coil temperature monitoring and over-temperature protection.
The PCBA module is filled with potting compound.
Clean off the potting compound. The front of the PCBA module has a USB-C port, a boost inductor, a master control chip, four filter capacitors, a battery protection chip, and an SMD power button.
The back also has potting compound.
Clean off the potting compound. There are four resonant capacitors, a wireless power transmitter, and a wireless charging master control chip on the back.
The master control chip is from iSmartWare. This is a highly integrated multi-protocol bidirectional fast charging power bank dedicated all-in-one chip. It integrates 5A high-efficiency switch charging, 22.5W high-efficiency synchronous boost output, and multiple fast charging protocols such as PPS, PD, QC, AFC, FCP, PE, and SFCP. Model is SW6201S.
There is the information about iSmartWare SW6201S.
The alloy inductor is used to improve conversion efficiency. 2.2μH.
These are 4 filter capacitors connected in parallel.
The integrated battery protection chip is from Xysemi. It is used for battery overcharge, over-discharge, and over current protection. It adopts CPC5 package. Model is XB7608.
The wireless charging master control chip is from i-Core. It is a general-purpose flash memory MCU with a built-in enhanced 1T 8051 core, built-in analog comparator, op amp, 6-channel PWM output, SPI, I2C, and UART interfaces for wireless charging control. It adopts QFN24 package. Model is CMS8S6990.
The wireless charging power stage chip is from SouthChip. It is a 15W full-bridge power stage with voltage/current demodulation for highly-integrated wireless power transmitter. It adopts QFN19 package. Model is SC5008.
There is the information about SouthChip SC5008.
These are four NPO resonant capacitors.
These are LED lamp beads.
The USB-C port has a black plastic sheet.
There is the SMD button.
Well, those are all components of the OPPO 5000mAh Slim Magnetic Power Bank.
Summary of ChargerLAB
Here is the component list of the OPPO 5000mAh Slim Magnetic Power Bank for your convenience.
It has 10W wireless and wired fast charging capabilities, supports 12W maximum input power, and has an exquisite and lightweight appearance.
After taking it apart, we found it adopts a 5000mAh soft pack battery from GFL, with a nominal voltage of 3.87V. The MCU adoptsiSmartWare SW6201S. The PCBA module is filled with potting compound for heat dissipation. The battery pack and coil are surrounded by barley paper for insulation and foam for buffering protection. The workmanship is solid.
