■ Press: 360, E-color, Beth, Locke has better compatibility with the test mobile phone, and the charging speed is faster.
Recently, the Shenzhen Municipal Consumer Commission announced the comparative test results of wireless charging of 10 hot-selling car mounts on the market.
The test results show that the wireless charging samples of 10 car mounts meet the test requirements, of which 4 samples of Bess, Locke, Yise and Greenlink have performed well in all aspects and have been rated five stars.

Poor compatibility between mobile phones and wireless chargers, serious heat generation, hardware mismatch, etc. will lead to slow charging speed.
This compatibility test simulates the actual use scenarios of ordinary consumers, and the actual input power of the three test mobile phones is wirelessly charged from the car bracket and whether it reaches the declared value is assessed.
The results show that the 360, Ese, Bess, and Locke samples have better compatibility with the test mobile phones and charge faster.
In terms of charging time, the performance of samples of each brand varies, ranging from 2 hours and 12 minutes to 7 hours.
This comparative test measures the charging time required for three mobile phones from 0% to 100%.
The results show that the shortest charging time of Apple 12 mobile phones is: Locke (2:32), Beth and Greenlink (2:37); the shortest charging time of Huawei P40 pro mobile phones is: Yise (2:15), 360 (2:22); The shortest charging time of Xiaomi 11 mobile phones is: 360 (2:12), Zhaowei (2:14).

Huiduoduo, Locke and GreenLink performed well
Charging protection mainly refers to whether the wireless charging device will enter standby or enter the low-power charging state when the receiving device (mobile phone) is fully charged, so as to avoid the continuous high-power charging of the wireless charging device, overcharging, overheating, short circuit and so on.
Foreign body detection refers to when the charging area of the wireless charging device is detected by the metal foreign body, will take automatic power off, temperature control or stop the work of a protection function, if the function fails, will make the metal object quickly produce high heat, resulting in equipment damage or cause accidents such as accidents
This comparative test was evaluated from four aspects: foreign object warning of wireless charging equipment, foreign body detection ability, wireless charging input power after placing foreign body, and foreign body temperature.
The heat requirement test is assessed from the surface temperature of wireless charging and the temperature of the front and back of the three test phones (Apple 12, Huawei P40 Pro, Xiaomi 11) (below 48 ° C).
Based on the above three test results, the samples of Huiduoduo, Locke and GreenLink performed well and were rated five stars.

Beth, 360, GreenLink and other performance is better
The 10 samples participating in the test performed differently in the three aspects of Qi logo certification, product ontology logo, and environmental protection logo, and each had its own shortcomings.
In addition, the five products of Beth, Tulas, 360, Greenlink and Suning Xiaobiu have done a good job in the label identification requirements of the wireless charging part.
<h1 class="pgc-h-arrow-right" data-track="73" > consumption tips</h1>
1. At present, there is no Apple's official car bracket wireless charging products, when selecting third-party products, the maximum compatibility power is only 7.5W, so Apple mobile phone users do not need to blindly pursue the maximum power products when choosing. Android mobile phone users can choose according to the compatibility of the product claimed, and choose according to the demand.
2. Users who use mobile phone cases should pay attention to the fact that there is no metal in the mobile phone case before use.
3. Try to avoid high temperature, so as not to reduce the firmness and service life of wireless charging.
