We all know that Hangjia in the power supply industry is a comprehensive strength of the head brand enterprises, Hangjia in the mobile phone charger product development and manufacturing has more than ten years of experience, cooperation and service to many mainstream mobile phone manufacturers around the world, the production of a variety of reliable mobile phone brand charger products.
After the outbreak of the PD fast charging market, in order to meet the needs of consumers, Hangjia also entered the fast charging market, bringing a variety of reliable quality and safe fast charging products. Not long ago, the charging head network disassembled a 100W gallium nitride double certification safe fast charge.
Recently, Xiaobian received a mini 30W safe fast charge launched by Hangjia, the product focuses on small mini, multi-voltage output, multi-protocol compatibility and other selling points, and has also passed the national CCC safety certification, and the performance and quality are guaranteed. The following charging head network will disassemble this Hangjia mini 30W charger in detail to help the favorite friends fully understand it.
First, Hangjia mini 30W safe and fast charging appearance
The box is colored in blue and white, and the front is printed with the HuntKey hangjia brand, product name, appearance map and three major selling points.
The back side is printed with a product usage scenario diagram and parameters.
The package contains a charger and instruction manual.
Hangjia 30W safety fast charging adopts PC material white shell, waist bright surface design transition round, top surface frosting treatment.
The charger is equipped with a fixed GB pin.
The input housing is printed with charger parameters
Model:HKC03020015-0A1
Input: 100-240V~50/60Hz 1A
输出：5V3A、9V3A、12V2.5A、15V2A、20V1.5A
Manufacturer: Shenzhen Hangjia Chiyuan Electric Co., Ltd
The charger has been CCC certified.
The top surface is printed with the HuntKey brand logo, equipped with a single USB-C interface, rubber core blue, Hangjia brand color.
The measured height of the charger body is 35.03mm.
The width is 32.87mm.
The thickness is 32.74mm.
Compared with Apple's 30W charger, the volume advantage is huge.
The size of the hand is intuitive and very small.
The net weight is about 60g.
Using the ChargerLAB POWER-Z KT002, the charger supports Apple 2.4A, Samsung 5V2A, DCP protocols, as well as QC2.0/3.0, AFC, FCP, PD3.0, PPS fast charging protocols.
In addition, the PDO message shows that the C port also has five fixed voltage files of 5V3A, 9V3A, 12V2.5A, 15V2A, 20V1.5A, and two sets of PPS voltage levels of 3.3-11V3A and 3.3-16V1.8A.
Second, Hangjia mini 30W safe fast charge disassembly
Detach the top case of the charger and ultrasonically solder the package.
The charger is internally glued, and finally it has to be violently disassembled by cutting.
The 30W power level charger is rarely filled, and Hangjia has done it, relatively speaking, weather resistance, heat dissipation performance, etc. will be better, more stable and reliable.
The side panels are covered with white plastic plates.
At a glance at the input terminal, there are NTC thermistors and common-mode inductors on the bottom panel, and I-inductors, high-voltage filter electrolytic capacitors, main control chip power supply capacitors and transformers on the side panels.
The back of the board is equipped with a chip fuse, a rectifier bridge, a chip Y capacitor, and a protocol chip.
After the charger is plugged into the socket and energized, the current first passes through the patch fuse, the rated current is 4A, and the circuit is cut off by fusing.
Then through the NTC thermistor, NTC thermistor is used to suppress the inrush current when plugged in, reduce the spark of plugging, the temperature rises during normal operation, the resistance is reduced, and the loss is reduced.
Then pass through the common-mode inductor on the left side, and the two wires are wound and sheathed with insulated pipes to filter out EMI interference.
Then cross the LPR10L30 rectifier bridge to convert alternating current into pulsating direct current.
The pulsating DC is filtered into DC by an I-inductor and a high-voltage filter electrolytic capacitor, and this I-inductor jacket insulates the tube.
Two high voltage filter electrolytic capacitors from KoShin Dongjia Electronics are available in 400V 27μF and 400V 18μF, respectively.
The switching power supply main control chip power supply capacitor comes from Chang Changzhou Warwick Electronics, and the specification is 50V 4.7μF.
The back of the side panel is equipped with a switching power supply main control chip.
The direct current output after filtering through the electrolytic capacitor enters the primary side of the transformer, and the main control chip switches on and off at high frequency, and finally converts it into a low-voltage ALTERNA output through the transformer.
The switching power supply main control chip adopts PI SC1713C, which integrates PWM controller, high voltage switch tube and synchronous rectifier controller.
The right side of the transformer is covered with a plastic shell, and the alternating current is stepped down through the transformer.
The chip Y capacitor comes from WEIDY.
At a glance at the outputs, there are also solid filter capacitors on the side panels.
After removing the transformer and other devices, you can also see that there is a synchronous rectifier.
There is an output VBUS switch next to the USB mother.
The main control chip controls the synchronous rectifier tube for rectification, converting the transformer output low-voltage alternating current into low-voltage pulsating direct current. This synchronyping tube is from AOS.
The pulsating DC is then filtered into DC by a solid capacitor. This solid capacitor is from Yubang and has a specification of 25V 560μF.
The interface protocol chip adopts Ingenics IP2726, which is a fast charging IC that integrates multiple protocols for USB output ports, supporting Type-C DFP, PD2.0/3.0, PPS, QC4+, QC2.0/3.0, FCP, AFC, SCP, MTK PE+, Apple2.4A, BC1.2 and Samsung 2A. With high integration and rich functions, it requires very few peripheral devices in the application, effectively reducing the size of the overall solution and reducing the BOM cost.
The charging head network learned that the Inji core IP2726 has passed the Qualcomm QC4+ certification and obtained the first QC4+ certification certificate Chinese mainland.
Charging head network learned that Yingji core IP2726 has previously been adopted by Motorola 68W gallium nitride charger, Nubia dabai 20W dual-port gallium nitride charger, AOHi 100W dual USB-C port gallium nitride fast charge, bull fast charge 86 panel, AUKEY 65W 1A1C gallium nitride fast charge charger and other products. In addition, other series of fast charging chips of Yingjixin have also been highly recognized by customers such as Xiaomi, Huawei, and Samsung.
The output VBUS switch tube was accidentally damaged when splitting the two small boards, and it can be seen from the silk screen that it is the VS3610AE, withstand voltage 30V, PDFN3333 package.
Wei Zhao VS3610AE data information.
Charging head network disassembly learned that the use of Weizhao VS3610AE also has Xiaomi 11 Pro/Ultra standard 67W fast charge, Aohi mini 30W gallium nitride charger, Olympian Technology 45W mini gallium nitride charger, bull 65W gallium nitride charger, Lenovo Savior 45W PD fast charger, Greenlink 65W gallium nitride fast charger and other products, while using Weizhao other MOS also xiaomi 6 port USB charger 60W fast charge version, zimi 65W PD mini charger, RaVPower 45W GaN PD charger, Huawei 20W charge pump fast charge charger, Beth 45W PD fast charge charger and dozens of other products are used.

All dismantled, come to Zhang Hangjia 30W safe and fast charge family portrait.
Charging head net disassembly summary
The launch of this mini 30W safe fast charging of Hangjia is to fill the gap in the 30W power level fast charging of its products. This charger is not only very compact, but also supports QC, PD, PPS, AFC, FCP multiple fast charging protocols, with 5-20V full voltage gear, as well as 3.3-11V3A and 3.3-16V1.8A two sets of PPS voltage gear, which can meet apple iPhone new machine full speed fast charge, but also charge tablets and other devices.
The charging head network learned through disassembly that this product is also one of the few in the 30W power level fast charging for filling treatment, and the overall reliability and heat dissipation performance are more excellent. It adopts Apple's original fast charging chip - PI SC1713C, with AOS synchronous rectifier tube to form a switching power supply, and the IP2726 protocol IC control interface output of Yingji core. Dongjia and Yubang two major brand capacitors for filtering, the overall material is solid and reliable.
