The measured length of this shared power bank body is 134.85mm.
The width is 70.02mm.
The thickness is 15.31mm.
The size of the power bank in the hand is intuitively felt.
In addition, its weight was measured to be about 142g.
Finally, the ChargerLAB POWER-Z MF001 was used to measure that the Lightning terminals were not original.
Street power x Sodian 5000mAh shared power bank dismantling
After reading the appearance display of this shared charging treasure, let's disassemble it and take a look at the internal design and workmanship.
Hidden below the data line that comes with the power bank is the fixing screw of the case.
Unscrew the set screws to disassemble the housing, and the housing is fixed by screws and clips.
There is a PCBA module at the bottom of the power bank, which is fixed by screws. The top power switch and indicator light are connected by a cable.
A thermistor that detects the temperature of the battery is also soldered on the PCBA module.
The cable connector is fixed by tape.
The batteries are connected by spot welding.
The PCBA module is fixed to the housing by screws.
Unscrew the fixing screws, take out the PCBA module, and remove the glue-fixed battery.
The self-supplied charging cable is connected by wire welding.
The included charging cable is secured through the opening of the case.
The battery is protected by a plastic cover.
Cut the connecting wires and separate the connection between the PCBA module and the housing.

SMD micro buttons and RGB LED close-up.
The LED driver chip is from Chipone, with ICND2038S model and supports 16 constant current drive outputs.
The lower left corner of the PCBA module is provided with a battery protection chip, and the main control chip and alloy inductor are provided on the right side.
The back is equipped with an NTC thermistor, a main control MCU and a voltage regulator chip.
The main control chip of the power bank comes from Zhirong, model SW6008, which is a highly integrated Type-C mobile power all-in-one chip, which supports USB-A+Micro USB+USB-C and Lightning or two USB-A + Micro USB+USB-C interface combinations. The chip integrates 3A high-efficiency switching charging and 3.1A high-efficiency synchronous boost output.
SW6008 also integrates the power metering function, 188 digital tube or LED power display and the corresponding interface control management logic, only a small number of peripheral components are needed to achieve a complete high-performance mobile power solution.
Zhirong SW6008 data information.
The 1.5μH alloy inductor is used with Zhirong SW6008 for voltage conversion.
The MOS tube of the silkscreen 8205 is used for output VBUS control.
The battery protection chip is from Saixin Micro, model XB4908, and the chip has an integrated protection tube inside the chip for overcharge, over-discharge and over-current protection of the battery.
The main control MCU inside the power bank is silkscreened CC2538.
The voltage regulator chip that supplies power to the main control MCU is silk-screened CHUF.
