What is the difference between 08?

At the previous "Endless" conference, Mi Xiaomi also launched a 80W sailing windless wireless charge in addition to the launch of the 11 Pro and 11 Ultra new machines. MDY-13-ED, the oversized wireless charging power can be said to defeat a lot of cable fast charging, once it was launched, it attracted great attention.
and on August 10, Xiaomi held the theme "My Dream, My choice" 2021 Lei Jun's annual speech. The Xiaomi MIX 4 was taken in the front. Among them, there is a 100W sailing windless wireless charge MDY-13-EE, which is now officially launched at 599 yuan.
The maximum power of this wireless charger reaches an amazing 100W. The wireless charging power will last a new level to continue leading the industry. However, friends who have followed attention should find that the two wireless charges of 80W and 100W are the same in modeling design. It seems that it is only different in color and different power.
The charging head network has now started with Xiaomi this new 100W sailing wind cold wireless charging MDY-13-EE. The following will be disassembled in detail to solve everyone's questions.
. The appearance of the Xiaomi 100W wireless charger
The packaging box is still black color. In the middle of the front is the pointed -angle pattern of Phnom Penh, which is lined with wireless filling type. On the upper floor, Xiaomi LOGO in the upper right corner also used the latest version.
The 100W wireless charging seat suit information stickers are posted on the back, and wireless charges, data cables and chargers are printed.
This on both sides of the box is "Xiaomi 100W wireless charging seat set" perm, making the packaging look more grade.
The packaging contains 100W wireless chargers, chargers, data cables, instructions and three packages.
This cable is Xiaomi's magic reform 6A fast charging line. The charging head network has been disassembled in detail.
The charger is Xiaomi's very well -known magic reform 120W super fast charging.
Xiaomi This 100W wireless charger uses a sail -shaped design, matte on the surface of the fuselage shell, black color scheme, and the mobile phone support platform is gold transparent acoustic block. The overall black gold color matching is also in line with the design of the box.
This on the front of the fuselage is printed with xiaomi, xiaomi Co., LTD. and Designed by xiaomi.
The front of the fuselage is concave, and there is a air outlet at the bottom. The mobile phone will naturally form a air duct. When charging, the wireless charging fan will take away the heat generated during the charging process to achieve the active heat dissipation effect.
This support platform adopts step -level design to effectively prevent mobile phones from slipping.
From the side, the fuselage has a certain tilt, and the mobile phone will not overwhelm during wireless charging. The two triangle connections seem fragile, in fact, the bottom is a metal plate support, which is very strong.

The charging head network disassembly summary
Xiaomi 100W sailing wind cold wireless charging MDY-13-EE is like its name, continuing sailing design, wireless charging power is as high as 100W, many cable fast charging on the market, continue Continue to write the "myth" of the wireless charging industry. The wireless charging interior of the active turbine air cooling system is used for heat dissipation, intelligent dynamic dynamic adjustment fan speed, and at night charging can inhibit noise and does not affect sleep.
This wireless charging also supports freely charging horizontally and vertically. In the speed mode, this product can be filled with Xiaomi MIX 4 100%power in 28 minutes. In addition, it is compatible with Xiaomi's own wireless charging mobile phone, Xiaomi 11 Ultra and other models. In addition, it has passed the QI certification of the wireless charging alliance, and supports equipment that uses Qi wireless charging standards on the market.
The charging head network disassembly learned that this wireless charging the same built -in Voda semiconductor NU1513 NU1028 high -integrated wireless charging scheme, the circuit is simple and complete. The Xiaomi 80W wireless charging based on this set of solutions has been verified by the market in terms of performance and reliability. It is believed that the power increase to 100W is also reliable.
Ip using Yingfei CyPD3171 port controller control input voltage, Nanxin SC8701 and Silicon Lijie SY8201 liter/antihypertensive solution to the coil and wireless charging control circuit, and also used Fengbin capacitors for filtering, which is generally used. The materials are basically the same and reliable.
In general, Xiaomi 100W sailing wind is cold and wireless charging MDY-13-EE shape, internal structure and materials are basically the same as 80W. As of now, Xiaomi's 80W wireless charging has only white models, and has not been launched in other colors. At present, 100W has only black gold color matching. Therefore, the two wireless charges are still very distinguished. Based on face value, performance, price, etc., friends can choose in combination with their own conditions.
