Introduction

ChargerLAB this time got a 15000mAh 20W power bank from Gendome. It adopts an aluminum alloy case for a long lifespan. There is a slot on the side of the case to store the cable.

It adopts two USB-C ports and a USB-A port, which can support an input of 18W and an output of 20W. One end supports wireless charging that can wirelessly charge the iWatch. Next, we are going to take it apart to see its internal components and structure.

Product Appearance

It adopts an aluminum alloy case and is sprayed with silver-grey metallic paint. The transitions between the four sides are rounded, and it feels good to hold.

The power button and battery indicator lights are located on the left side of it.

The "Gendome" is laser engraved on the right side.

The power indicator light is light blue. Each of the four indicator lights represents 25% power. You can know the approximate remaining power based on the number of lights on.

There is a slot on the back to store the cable, and the USB-C3 port is in the slot. It comes with a dual USB-C cable and a USB-C to Lightning cable which matches the slot, making it convenient to carry and use.

The included cable can be stored perfectly in the slot.

The length of the cable is about 12 cm (4.72 inches). The two cables are the same length.

The ChargerLAB POWER-Z MF001 shows the Lightning port is not original.

This end can support wireless charging. The wireless charging area is concave and can be used to wirelessly charge devices such as Apple Watch.

The other end is equipped with USB-A and USB-C ports, and below the port is the specs info.

The USB-C2 port can support outputs of 5V3A, 9V2.22A, and 12V1.67A. The USB-C3 port can support outputs of 5V3A, 9V2A, and 12V1.5A. When the USB-A port and any USB-C port are outputting at the same time, the output power is 5V3A. It has passed FCC and CE certifications.

The length of it is about 158 mm (6.22 inches).

The width is about 50 mm (1.97 inches).

The thickness is about 47 mm (1.85 inches).

That's how big it is in the hand.

The weight is about 473 g (16.68 oz).

The ChargerLAB POWER-Z KM003C shows the USB-C2 port supports FCP, SCP, AFC, QC3.0, PD3.0, and DCP charging protocols.

And it has three fixed PDOs of 5V3A, 9V2.22A, and 12V1.67A.

The ChargerLAB POWER-Z KM003C shows the USB-C3 port supports FCP, SCP, AFC, QC3.0, DCP, and Apple 2.4A charging protocols.

The ChargerLAB POWER-Z KM003C shows the USB-A port supports FCP, SCP, AFC, QC3.0, and DCP charging protocols.

Teardown

After the product's appearance, let's start to take it apart. 

First, remove the cover of the wireless charging panel.

Inside the cover are the fixing screws and the wireless charging coil.

The wireless charging coil is wound with Litz wire.

There are the screws for fixing.

Unscrew the fixing screws and push out the internal movement.

The PCBA module is fixed inside the plastic frame.

The battery is also fixed inside the plastic frame and cushioned with foam.

The PCBA module is fixed to the frame by screws.

This is the screw that fixes the PCBA module.

The wireless charging coil is connected by soldering.

Unscrew the fixing screws, separate the connection between the battery and the PCBA module, and remove the battery and the PCBA module from the frame.

The USB-C and USB-A sockets, power detection button, protocol chip, VBUS MOSFET, synchronous buck-boost circuit, and wireless charging chip are on the front of the PCBA module.

A thermistor is soldered on the back to detect the battery temperature.

The buck-boost chip is from SouthChip. It integrates an I2C port and supports input and output voltage ranges of 2.5-36V. It has under-voltage protection, overvoltage protection, and overcurrent protection. Model is SC8815.

Here is the information about SouthChip SC8815.

This is the alloy inductor and synchronous buck-boost MOSFETs.

The MOSFET of the battery side is from Tuofeng and adopts PDFNWB5 x 6-8L package. Model is TF025N06NG. 60V 2.5mΩ.

The two MOSFETs at the output end are of the same model.

The specification of the capacitor for input filtering is 100μF 16V.

The specifications of the solid capacitor for output filtering are the same.

The master control chip for wireless charging is from Injoinic. It is compatible with the latest WPC, Qi, and V1.3 standards, and supports 5W, Apple 7.5W, Samsung 10W, and 15W wireless charging. Model is IP6829.

Here is the information about Injoinic IP6829.

The protocol chip is from Chipsea. It has a built-in 8-bit RISC core, built-in 32K*16-bit FLASH, and built-in 2K SRAM. It supports fast charging protocols such as QC4, SCP, FCP, and AFC. Model is CSU3AF10.

These five VBUS MOSFETs are from Yieternal and adopt PDFN3333 package. Model is ET6303. -30V 8.5mΩ.

These four LED lights are used to indicate the remaining battery capacity.

The SMD button is used for power detection.

The battery protection chip marked with 12AB is from Hong Kang.

These two battery protection MOSFETs are marked with L2030.

The boost chip marked with Y5UH is from Microne.

This is the boost inductor. 22μH.

The regulated MOSFET used to regulate the output voltage is from Microne. Model is ME6203. 3.3V.

This is a thermistor used to detect the battery temperature.

Here is the blue USB-C socket. 

The USB-A socket is also blue. 

A thermal pad is pasted on the inside of the plastic frame at the position corresponding to the PCBA module.

The battery is glued inside the frame.

The positive terminal of the battery is connected with a nickel sheet.

The negative terminal of the battery is also connected with a nickel sheet. The blue plastic film pasted on the explosion-proof valve indicates the negative terminal.

The length of the battery is about 140 mm (5.51 inches).

The diameter of the battery is about 33 mm (1.3 inches), and it is a 33140 battery.

The battery is marked with 15AH and 48Wh. The battery type is LFP and the rated voltage is 3.2V.

Well, those are all components of the Gendome 15000mAh 20W Power Bank.
