Disassembly Report: UGREEN 10000mAh Magnetic Wireless Charging Power Bank
- Appearance of UGREEN Magnetic Wireless Charging Power Bank
The front of the box is printed with the brand, product name, appearance, and three major characteristics.
The package contains mobile power, data cable, storage bag and instruction manual.
The attached data cable is A to C cable, the thread end is frosted and the UGREEN brand is gravure printed.
The charging cable is about 53cm long.
This power bank has a flat and compact body, a matte shell surface, rounded corners, and a good overall feel, as well as a high-value appearance.
The front center of the power bank is printed with a circle wireless charging area, on which is the UGREEN brand logo.
With metal feet on the back, it has high strength and is not easy to break.
Open the support frame and change the power bank to the mobile phone holder in seconds.
There is a power button on one side of the fuselage and a bright decorative ring on the edge, which makes the product look more temperamental. In addition, it can be seen that the front of the power bank has a concave design, which is to reserve a position for the convex part of the mobile phone camera, so that the iPhone 12 and the mobile power supply fit more closely, thereby ensuring the stability of charging.

The PDO message shows that the USB-C port also has three sets of fixed voltage gears of 5V2.4A, 9V2.22A, and 12V1.67A, and a set of PPS voltage gears of 3.3-11V2A.
In addition, it is tested that the USB-A port supports Apple2.4A, Samsung 5V2A and DCP protocols, as well as QC2.0/3.0, FCP, SCP, VOOC/DASH/WARP, SuperVOOC fast charge protocols.
The mobile power bank has the same weight as the largest iPhone 12 Pro Max. It will be tightly attached to the phone when it is close to the phone, and it will not fall even if it is suspended in the air.
In addition, in daily use, you can unfold the feet and use it as a “vertical wireless charger”, and the experience of using it while charging is also very good.
2. Disassembly of UGREEN Magnetic Wireless Charging Power Bank
The body shell is disassembled, and the edges are encapsulated with buckles.
The PCB board is fixed with screws, and the wireless charging coil is fixed on the battery core, and is protected by foam.
A thermistor is fixed on one side for temperature monitoring.
Take out the PCB board and the battery core, there is a protective foam inside the body shell, and there is an isolation board at the junction of the corresponding circuit board and the battery core.
The metal feet are fixed with screws, and you can see that there is insulation tape on the corresponding area of the PCB board. The details are particular.
The front of the PCB board is covered with a brass heat sink to reduce the temperature rise during charging.
Remove the heat sink, the main control chip and the inductor are also pasted with thermal pads to help conduct heat.
Three places on the back are exposed copper and tin to enhance heat dissipation. Insulation tape is attached to the lower right corner, and there are two chips next to it.
The battery core and the PCB board are connected by spot welding of nickel sheets.
The main control chip of the mobile power supply adopts Yingjixin/Injoinic IP5568, which is an integrated wireless charging TX/RX, QC2.0/QC3.0/SCP output fast charging protocol, FCP/AFC/SFCP input and output fast charging protocol, MTK PE+ 1.1&2 .0 output fast charge protocol, USB-C/PD2.0/PD3.0 input and output protocol, USB-C PD3.0 PPS output protocol, compatible with BC1.2/Apple/Samsung mobile phones, synchronous boost/buck converter, Lithium battery charge management, battery power indicator and other multi-function power management SOC provide a complete power solution for fast charging mobile power.
IP5568 can support USB-A x 2, USB-B, USB-C four USB ports at the same time. Any one of the USB ports can be used alone to support fast charging. When two or more output ports are used at the same time, only 5V output is supported. When IP5568 supports wireless charging and USB port at the same time, the USB port also supports input and output fast charging function.
In addition, Injixin IP5568 has also passed Qi certification. The WPC official website page shows that it has passed the latest Qi V1.2.4 certification, the Qi certification ID is 7485, the registration type is the transmitter, the certification type is BPP certification, and the power is 5W. With the support of Qi certification, the wireless charging compatibility and safety of the product are more guaranteed.
Close-up of 2R2 alloy buck-boost inductor, 10*10 large size reduces heat generation and improves efficiency.
Filter solid capacitor, the specification is 16V 100μF.
LED Indicators。
USB-C Female Socket。
A close-up of USB-A female socket, sink plate through-hole welding, widened positive and negative poles for high-current charging.
Wireless charging coil, Litz wire wound. The edge of the coil is a circle of magnets used to attract the mobile phone.
After all the dismantling is complete, let’s take a family portrait.
WOKOO DESIGN Disassembly Summary
UGREEN’s magnetic wireless charging mobile power bank has a capacity of 10000mAh and strong adsorption capacity. It can provide stable magnetic charging for iPhone 12. It is also medium in size and suitable for daily use. The whole body is silver-gray, and the edge is designed with a decorative ring. The overall appearance is high and it has a good feel in use. In addition, there are feet on the fuselage, which can be turned into a “vertical wireless charging” with the magnetic suction, which can meet the demand of playing games while charging. The 1A1C interface of the power bank supports QC, SCP, PD3.0, PPS and other fast charging protocols, which can meet the iPhone 12 20W fast charging, Huawei 22.5W fast charging, etc., and the performance is practical.
WOKOO DESIGN, through the disassembly, it is found that the internal circuit of the mobile power supply is quite simple. An Insets IP5568 main control chip can realize the control of all the functions of the whole machine, and the integration level is very high. In addition, the well-known ATL battery cells are used, which are reliable in quality. They are equipped with lithium battery protection circuits and thermistors to protect the cells. The cells themselves are fixed with foam. The PCB board and wireless charging coil are equipped with heat sinks, and the overall workmanship details are exquisite.
