Xiaomi has launched a unique 80W sail wireless charger in 21 years. The sail design is full of artistic sense, with built-in double coils. The mobile phone can be charged wirelessly both vertically and horizontally.When Xiaomi 14 Ultra was released this year, it also brought a new 80W lift air cooled wireless charge with small sensing wireless charging technology.
Although it also supports up to 80W wireless charging, the compatibility of Xiaomi 14 Ultra is also different due to design and technology differences. The 80W Sail wireless charging can only support up to 50W wireless charging while the new vertical air-cooled wireless charging can reach 80W, but due to the unavoidable heating problem of wireless charging,Wind sail wireless charger has a larger volume and built-in fan. How about the specific charging performance of the two wireless chargers? Let's have a look at the comparative test.
Appearance performance comparison
Xiaomi 80W elevating air-cooled wireless charger (left side) adopts classic pure white color matching, ergonomic vertical support design, and the bottom is suspended.The front bottom tray is equipped with a twill rubber pad to prevent sliding. At the same time, there is a groove between the rubber pad and the wireless charger body, which is used as an air outlet to facilitate heat dissipation.
Xiaomi 80W Sail Wireless Charger (right side) adopts the sail shape design, the wireless charger body adopts PC flame retardant material shell, the surface is matte, and the mobile phone support platform adopts transparent acrylic block design.The support platform adopts a stepped design, which can effectively prevent the mobile phone from sliding.
The back surface of Xiaomi 80W elevating air-cooled wireless charger is concave right angled bevel design, and the Type-C port with an orange rubber core is located below;The Xiaomi 80W Sail Wireless Charger is designed as a flat slope, with an LED indicator on the top, which lights green when working, and a white rubber core Type-C port on the bottom.
From the side, the new lift type wind cooling wireless charging volume is significantly smaller than the old model sail wireless charging.
In terms of weight, the new lift air-cooled wireless charge is 180.7g, and the old model of sail wireless charge is 208.5g.
In terms of charging power, Xiaomi 14 Ultra and the original 120W charger were used together with Xiaomi 80W elevating air-cooled wireless charge and Xiaomi 80W sailboat air-cooled wireless charge for wireless charging. The measured new elevating air-cooled wireless charge reached 75.06W, while the old version of the sailboat wireless charge was 48.67W, in line with the official promotion of 80W and 50W wireless charging.
Charging comparison
Comparison of whole charging test
Next, let's take a look at the charging performance of this Xiaomi 14 Ultra with Xiaomi 80W elevating air-cooled wireless charge and Xiaomi 80W sailboat air-cooled wireless charge. After the mobile phone has run out of power, put the mobile phone, Xiaomi 80W elevating air-cooled wireless charge and Xiaomi 80W sailboat air-cooled wireless charge into the 25 ℃ incubator respectively, connect the power supply, and record the data.
Let's take a look at the charging performance of Xiaomi 14 Ultra with Xiaomi 80W elevating air-cooled wireless charge.
After the power is connected, shake hands with 20V voltage;The peak power in the first three minutes is 60W;The power is reduced from 51W to 35W within 7 minutes;Then the power fluctuates between 27-30W and lasts for 58 minutes;Then the power drops to 19W and lasts for 1h and 01min;Finally, the power suddenly drops and the battery is fully charged in the first hour and five minutes.
Take a look at the charging performance of Xiaomi 14 Ultra with Xiaomi 80W sailboat air-cooled wireless charging.
After the power is connected, shake hands with 20V voltage;The power reaches the peak value of 50W in the first three minutes;Then it dropped to about 44W and maintained for 1 minute;Then the power was reduced to 38W for 1 minute;Then the power was reduced to 32W and maintained at 11 minutes, then the power fluctuated between 29-36W and lasted for 46 minutes;Finally, the power drops sharply and is charged to full power in the first hour and 10 minutes.
Plotting the results of the two tests into a curve, it can be seen that the Xiaomi 80W elevating air-cooled wireless charge is about 5 minutes faster than the Xiaomi 80W sailboat air-cooled wireless charge. The power of the Xiaomi 80W elevating air-cooled wireless charge is about 60W at the initial stage, 10W higher than the sailboat air-cooled wireless charge. In the later stage, the power is kept at 27-30W for a long time.Although the charging time of Xiaomi 80W sailboat air-cooled wireless charging is higher than that of Xiaomi 80W lift air-cooled wireless charging, the charging time is shorter and the end trickle charging time is longer.
Summary: Xiaomi 80W elevating air-cooled wireless charge can better adapt to Xiaomi 14 Ultra mobile phone, and obtain higher charging power. Charging is slightly faster than Xiaomi 80W sailboat air-cooled wireless charge.If the original Xiaomi 80W sailboat air-cooled wireless charging user upgrades the Xiaomi 80W lift air-cooled wireless charging, the perception of charging efficiency improvement is not significant.
Charging temperature test comparison
After 30 minutes of charging, use the thermal imager to take pictures of the connection between the mobile phone and the Xiaomi 80W sailboat air cooled wireless charging. The maximum temperature is 37 ℃.At this time, the charging power is about 29-36W.
After 30 minutes of charging, use a thermal imager to take a picture of the connection between the mobile phone and Xiaomi 80W elevating air-cooled wireless charging. The maximum temperature is 36.4 ℃.At this time, the charging power is about 27-30W.
Summary: After charging Xiaomi 14 Ultra for 30 minutes, the power of Xiaomi 80W sailboat air-cooled wireless charging is slightly higher than that of Xiaomi 80W lift air-cooled wireless charging, and the heating is also about 0.6 ℃ higher.
Summary of charging head network
The Xiaomi 80W elevating air-cooled wireless charger and the old version of Sail wireless charger use Sail, although they also support up to 80W wireless charging, due to differences in design and technology, the compatibility of Xiaomi mobile phones such as Xiaomi 14 Ultra is also different.The lift air cooled wireless charger is smaller in size and lighter in weight, and adopts the classic pure white color matching;The wireless filling model of Xiaomi 80W sail is more unique.
In terms of charging comparison, the Xiaomi 80W elevating air-cooled wireless charging with small sensing wireless charging technology can better adapt to the Xiaomi 14 Ultra and obtain higher charging power. Charging is slightly faster than the Xiaomi 80W sailboat air-cooled wireless charging;In terms of the total charging time, the whole process of the new 80W air-cooled wireless charging is 1 hour and 5 minutes, which is only 5 minutes faster than the old model of windsurfing wireless charging. The perception of charging efficiency improvement is not significant, and users can choose according to their actual needs and preferences.
