The whole package is still ordinary colored cardboard, with product pictures and several necessary selling points on the front and product parameter information and factory information on the back. Manufacturer: Jiangsu Mizi Electronic Technology Co., Ltd. Manufacturer: Nanjing Kuke Electronic Technology Co., Ltd. Because the product is connected to 220V high-voltage power supply, it needs to have mandatory 3C, so the manufacturer, manufacturer and manufacturer are clearly marked on the product packaging. The following is the old habit before starting. Let's list the parameters first:
Of course, the performance of the above parameters in actual use will be disassembled and analyzed with you later. Let's talk about related accessories: 65W desktop charger rice, complete accessories: product host, AC power cord, instruction manual, and double-headed USB-C cable supporting high-power storage of adhesive tapes.
In terms of the overall appearance of the product, the 65W desktop charger of Mizi adopts a black appearance, and the surface of the product adopts a design similar to a sawtooth groove. The non-slip foot pad is placed at the bottom of the product charger, and the overall flat cuboid design not only fully shows the texture, but also looks full of beauty. Having said that, let's mainly talk about its functional configuration:
The 65W desktop fast charging equipment Mizi is equipped with two USB-C interfaces and one USB-A interface. In the demand scenario, more consideration is given to the mixed use of high-power devices such as notebooks, mobile phones and game consoles and low-power digital products. The maximum power configuration of the whole charger is 65W, and the Mizi has made a very optimized configuration in power distribution. First of all, the USB-C 1 interface, that is, the leftmost interface of the charger, can support 65W when used alone, that is, full load output. It can be fully compatible with the charging requirements of most notebooks, ultra-thin books and game machines on the market at present. When one of the other two USB-C2 or USB-A on one side is used at will, the power of USB-C 1 on the left side drops to 45W, which can also meet the charging requirements of notebooks, game machines and tablets. The remaining 18W power is allocated to the USB-A or USB-C2 interface in the middle, which is acceptable to ensure that it also has 18W power. That is, the functions of simultaneous multi-port use and multi-port fast charging are realized. Finally, even if all three ports are used, the leftmost USB-C 1 interface can still support 45W fast charging output, which ensures the use of high-power equipment.
Compared with the multi-USB interface charging on the market at present, this function has greatly improved its practicability compared with the multi-port charging method that can only be used in 5V mode. After the power distribution, how does this Mizi 65W desktop charger perform in fast charging compatibility? Small language test alone: USB-C 1 interface on the leftmost side of the charger only supports PD2.0/3.0 protocol, and it is turned on in 5v/9v/12v/15v/20v mode with the maximum power of 65W.
The USB-C2 interface in the middle only supports PD2.0/3.0 protocol in the charging protocol, and it is open in 5V/9V/ 12V mode, with the maximum power of 18W, mainly for low-power digital devices, such as iPhone, iPad and Android phones.
Finally, after testing, it supports the USB-A interface on the right. Android DCP 5V- 1.5A high current mode and Apple 5V-2.4A high current mode support QC2.0/3.0, but do not support Samsung AFC, Huawei FCP and other common fast charging protocols. Xiaoyu is quite surprised here, because for a desktop fast charging charger, of course, the more compatible protocol types, the better, and in the previous tests of Mizi's mobile power supply and charger, Samsung AFC and Huawei FCP are all supported and compatible. If compared with the previous products, the compatibility of this charger is really a little worse.
After talking about the compatible fast charging protocol, the last thing worth mentioning is the double-ended USB-C cable that comes standard with this 65W charger. The main reason for taking this accessory out for everyone to see is that the total length of this double-ended USB-C is nearly 1.5 meters, and the length is very sufficient. In addition, more importantly, not every USB-C terminal is equipped with an E-Marker chip because this double-ended USB-C line supports high power and high current. It can support 5A current at most, and this configuration completely reaches the level of notebook charging cable.
Here, Xiaoyu successfully read the built-in electronic tag chip through the instrument. The biggest function of this chip is to play the role of over-current protection to prevent large current from damaging devices with high charging current such as notebooks and tablets. At present, the mainstream ultra-thin notebook on the market, as long as it is powered through USB-C interface, the original USB-C charging cable will have an E-Marker chip built in. Compared with the ordinary and cheap double-ended USB-C wires on the market, most of them don't have an E-Marker chip. Although it can be used, its security and compatibility cannot be guaranteed.
Finally, the clutter communication output by the charger, that is, the ripple of DC output, is tested. The unit of ripple is MV (millivolt), because the greater the output power, the greater the ripple will be, so I directly tested the ripple of the charger with an instrument at a full load output of 65W, which is about 32.2mV, and the value can be said to be very small, far higher than the mandatory standard of the national standard. It also shows from one side that the rice charger is very good in selection scheme, circuit optimization and material selection.
Similarly, in order to test compatibility, Xiaoyu found iPhoneX, iPad Pro, macbook Pro, Xiaomi Notebook, Huawei Matebook and Lenovo yoga as the actual test objects, and analyzed their compatibility on the spot. Because it is borrowed temporarily, some devices have a lot of remaining power, which may not be full when actually charging.
First, charge the iPhone and iPad pro respectively. After using the purple USB-C lightning cable, the iPhone successfully shook hands with PD for fast charging, and the charging power was maintained at about 12W, while the iPad pro was tested with 47% remaining power, and the charging power reached about 30W, exceeding the power of the official standard 18W charger. Therefore, for students who use iPad pro, if they can buy a charger compatible with PD fast charging, the charging speed can be completely shortened by half.
Macbook Pro 18 Edition 13 inch, charging with double-ended USB-C cable as the standard charger, successfully shaking hands in 20V mode. The charging power reached 47W. Charging the notebook has been basically satisfied.
Huawei MateBook 13 inch, charged with the standard of double-ended USB-C line in the charger, and the handshake was successful. Charging started in 15V mode, and the measured power reached about 32W.
Xiaomi notebook 13 inch version, the charger comes standard with double USB-C cable charging, and the 20V mode successfully shakes hands. The measured power reaches about 52W.
Lenovo yoga high-end ultra-thin business book, the charger comes standard with double USB-C line charging, and the 20V mode successfully shakes hands. The measured power reaches about 44W.
Reason one: the appearance technology is improved and the details are exquisite;
Reason 2: 65W high power can feed more equipment;
Reason 3: it can support the charging of various electronic products, such as mobile phones, Switch, cameras, tablets, laptops, etc.
Reason 4: dual USB-C and USB-A can support high-power charging of two devices at the same time;
Reason 5: The price 145 yuan is more cost-effective than similar high-power chargers;
Problems needing improvement in products:
1 and USB-A support less fast charging protocols;
Summary: For a desktop charger, the Mizi 65W charger basically meets the needs of daily desktop use, and can replace notebook charging, mobile phone charging and tablet charger at the same time, which is a good desktop charging station product. Although there are still some shortcomings in mobile phone fast charging, it can fully integrate the daily desktop charging of computers, tablets and mobile phones. And supports multi-port simultaneous fast charging.
