In July 2019, Zimi launched a super small charger ha712, which caused a market sensation when it went on the market. At that time, the market was basically large-scale old-fashioned chargers, and Zimi ha712 let consumers see the R & D strength of Zimi.But in February 2020, Xiaomi ad651 came into the market, all of them are single port small volume chargers. What's the difference between them?


Let's talk about the appearance first,Purple rice HA712 with bright black face The new family ID design, In the frosted part, 65W power words are very beautiful.Millet AD651 maintains millet 's consistent style of sexual coldnessThere is no silk screen on the shell with bright white surface.


In terms of pins, Xiaomi ad651 and Zimi ha718 both use folding pin designWhen carrying out, the pins can be put in flush with the charger to avoid scraping with the luggage.


In terms of output interface, both Xiaomi ad651 and Zimi ha718 are single usb-c output, with the maximum output power of 65WIt can provide power supply for mobile phones, tablet computers and laptops.


The size of purple rice is 50mm * 50mm * 28mm, the weight is 96g, the same size of millet is 50mm * 50mm * 28mm, the weight is 96g, and the power density of both products has reached 0.92w/cm.


In terms of fast charging agreement,Both Xiaomi ad651 and Zimi ha712 support apple 2.4a, Qualcomm qc3.0, Samsung AFC and Huawei FCP fast charging protocols,It can provide fast charging for most devices, and the fast charging agreement of the two products is completely consistent.


In terms of USB PD, the two products are based on pd3.0 version, and PDO message feedback five fixed voltages, respectively: 5v3a / 9v3a / 12v3a / 15v3a / 20v3.25a. The complete PDO voltage does not support the PPS function, and the two chargers are consistent.


Xiaomi ad651 dismantling list, the transformer and its surrounding solid-state capacitance and electrolytic capacitance are fixed by gluing, and the primary electrolytic capacitance and small PCB are also separated by black plastic plate. From the diagonal side, the input terminal is equipped with delay fuse, safety gauge x capacitor, two common mode inductors, six primary filter electrolytic capacitors and PWM main control chip power supply capacitor and other components.


Purple rice HA712 disassembly map, the transformer actually says Xiaomi ad651 and Zimi ha712 both use Infineon primary switch tube ipl60r185c7, MPs secondary synchronous rectifier controller mp6908, Toshiba's secondary synchronous rectifier tube tph4r10anil and Weiquan's USB pd3.0 certification chip wt6636f, use Aihua high voltage electrolytic capacitor, and the output adopts solid-state capacitance filtering.

Summary:Whether it's the size, performance or even the materials for disassembly,Xiaomi ad651 and Zimi ha712 can be understood as the same products with small volume and large power, which also proves that the scheme is stable and reliable, and it is mature enough to be copied directly without any change.

In terms of price, the price of Xiaomi official mall ad651 is 129 yuan, while Zimi ha712 fluctuates between 129 and 149 on major e-commerce platforms. The only difference is the appearance.
