The white packaging box is equipped with a hook to facilitate offline sales display, and the front is printed with the appearance of the mobile power supply, and several major selling points of the mobile power supply are marked with pictures and texts.
On the back of the box are detailed product specifications.
The side of the box is printed with the number of times this charging treasure charges different electronic products.
In addition to the power bank, there is a charging cable and an instruction manual in the box.
The charging cable is a MicroUSB port.
This power bank has a long strip shape, the corners are rounded and transitioned, and it is more comfortable to hold in the hand.
There is a power switch button on the side near the output connector.
On the corresponding side are four LED battery indicators.
The function information is marked on the back interface of the power bank, and the detailed specification information is printed below.
HIPER RPX30000, USB-C and MicroUSB inputs: 5-12V 18W, USB1 and USB2 outputs: 5V3A, Max 15W, QC fast charge output 5-12V 18W, USB-C interface output 5-12V 18W, capacity of 30000mAh, battery energy 111Wh.
The output is configured with two USB-A ports, a USB-C interface and a MicroUSB interface.
The length of the power bank is about 150.7mm.
The width is approximately 77mm.
The thickness is approximately 41.5mm.
The net weight of the power bank is about 597g.
This power bank compares to the size of the iPhone 13 Pro Max.
The capacity of 30,000mAh is in hand, and the weight is full.
The USB1 port output protocol was measured by the ChargerLAB POWER-Z KT002, and the display supports Apple 2.4A, Samsung5V2A, DCP protocol, as well as QC2.0/3.0, AFC, FCP, SCP, MTK PE and other fast charging protocols.
The output protocol of the USB2 interface is exactly the same as that of the USB1 interface.
The USB-C interface output supports Apple 2.4A, Samsung5V2A, DCP protocol, as well as QC2.0/3.0, AFC, FCP, SCP, MTK PE, PD3.0 and other fast charging protocols.
The PDO message display USB-C interface has three fixed voltage levels of 5V3A, 9V2A and 12V1.5A.
HIPER 18W fast charge mobile power bank disassembly
The mobile power supply housing is assembled with snap-on clips, and the battery pack and PCB board inside are visible after the housing is opened.
The battery pack is patched with foam shock absorption, and the PCB board is fixed to the housing using screws.
The battery pack is a number of cells connected in parallel, and is insulated with tape, and then connected to the positive and negative poles of the PCB board through two wires.
The battery pack and PCB plate mold are removed from the shell, and it can be seen that the battery pack is fixed with the shell using a large amount of silicone, and the bottom of the battery is pasted with shock absorbing foam.
The mobile power supply adopts three lithium-ion batteries inside, welded together in parallel.
The design of the main control PCB board is very simple, centered on a mobile power supply main control chip, and the two USB interfaces are welded by the sink plate to achieve symmetrical design.
The back of the PCB board is equipped with a power switch button and a 2.2μH alloy inductor on the right side, an LED power indicator on the left side, and two lithium battery protection chips next to the black negative wire.
The lithium-ion battery adopts Jiatuo New Energy, with a single-chip battery cell of 10000mAh, a voltage of 3.7V and an energy of 37Wh.
Lithium battery protection chip adopts Sedicum micro XB7608, which is an all-in-one lithium battery protection chip, built-in 14.5mΩ conductive resistance MOS tube, peripheral components only need a capacitor, support overtemperature protection, overcharge protection, support overdischarge protection and short circuit protection, its internal integrated high-precision voltage detection, ultra-low quiescent current.
Another Sedic micro XB7608 protection chip.
Zhirong SW6228 is a highly integrated multi-protocol bidirectional fast charging mobile power dedicated all-in-one chip, support A+ A + B + C + L port any port fast charge. It integrates 5A high efficiency switch charging, 22.5W high efficiency synchronous boost output, supports PPS, PD, QC, AFC, FCP, SCP, PE, SFCP and other fast charging protocols, fuel metering, digital tube/LED lamp display and corresponding control management logic. Only a small number of peripheral devices are required to form a complete high-performance bidirectional fast charging mobile power solution.
Detailed specifications of Zhirong SW6228.
Buck-booster inductors for fast charging.
Two 8205A MOS tubes for interface switching.
Two additional MOS tubes of 8205A.
USB-A interface close-up, built-in blue rubber core, two sides of the pins widened processing.
USB-C interface and MicroUSB interface close-up.
Power switch button close-up.
The LED battery indicator close-up supports fast charge status indication.
The mobile power supply is all disassembled.
Charging head net disassembly summary
HIPER 30000mAh mobile power supply mains large-capacity, multi-interface product selling points, large capacity can be used as a backup power supply for mobile phones, tablets and other products, improve the endurance of the device, equipped with two USB-A interfaces and a USB-C interface support output function, single port can achieve 18W power fast charging, and can meet the needs of three mobile phones charging at the same time; in addition, this mobile power supply also retains the MicroUSB interface, taking into account the use experience of old users.
Charging head network disassembly learned that this mobile power supply built-in three pieces of Jiatuo new energy lithium polymer battery, and the use of Zhirong Gao integrated mobile power chip SW6228, a chip to complete the mobile power supply charge and discharge, multi-interface protocol control, LED power display and other functions, simplifying the peripheral circuit design, and optimize the cost.
