1, the amount of charging within minutes reaches or exceeds 10%, and the charging efficiency is even higher than the direct use of wireless chargers. In contrast, the Deep Blue SL0 Long comfortable Da and Wei brand Blue Mountain DHT-PHEV are obviously not too friendly for Apple iPhone 13 Pro, with a 15-minute charge of 3%, which is a large gap compared with other test models.
2, ▲ The induction key bin and the middle of the stick is a wireless charging board, you can charge the mobile phone, our home queen with the Oneplus 10 Pro has 5000mAh large battery, support 80W wired super flash charge and50W wireless flash charging technology, respectively, can be fully charged in 32 minutes of wired fast charging and 47 minutes of wireless charging to the phone, usually put the phone on the charging board after the car, basically full to the location, or more convenient.
3, battery charging part, Samsung S20 Ultra uses 5000mAh ultra-large capacity battery, and supports 45W wired charging power and 15W wireless charging power and 5W wireless reverse charging function. The Huawei P40 Pro uses a 4200mAh capacity battery, and supports 40W wired charging and 27W noneLine charging function, while supporting 5W reverse wireless charging function. In comparison, there is no doubt that the battery life and charging experience of the Samsung S20 Ultra phone are relatively better.
4, "Electric vehicle wireless charging system Part 2: Communication protocol between vehicle charger and charging device" (GB/T 38772), "Electric vehicle wireless charging system Part 3: Special requirements" (GB/T 38773), "Electric vehicle wireless charging System Part 4: Electromagnetic environmental Limits and Test methods (GB/T 38774) a total of 4 itemsNational standards.
5, wide impedance range, to meet a variety of needs of the inductance of the wireless charging coil is usually at the micro hen level, the test frequency is in the kHz range, which requires a wide and accurate measurement range. The E4980A/AL has a wide impedance range from 4 milliohm to 100 milliohm, and can cover this band with 10% accuracy, making it particularly suitable for the precise evaluation of wireless charging coils.
6, although the accessories are slightly unreasonable, but Huawei is the most comprehensive product in the test, the product texture and performance are very outstanding, of course, for this you have to pay as much as twice the price of similar products.What is the power and charging distance?
Generally about 0.9-2 meters high-power wireless charging transmission distance up to 5 meters wireless charging technology can be divided into low-power wireless charging and high-power wireless charging two ways. Low-power wireless charging often uses electromagnetic induction, such as the Qi method of charging mobile phones, but ZTE's electric vehicle wireless charging method uses induction.
The distance is greater than 10 cm, and the conversion efficiency is only about 60%, that is, the sent power is 1000W, and the received power is only 600W.
If the charging efficiency is relatively positiveIn terms of standards that are not harmful to the human body, the farthest distance that can be done now should be 5-10cm, and domestic micro goose technology and Qualcomm should be able to do it. And this is not the public familiar with Qi wireless charging, is magnetic resonance wireless charging, based on the principle of magnetic resonance. Although there are also 1 meter or even farther wireless charging technology, but the current charging power of these are too small, charging speed is too slow, difficult to put into daily use.
Wireless charging distance mobile phone and charger can not leave more than 10cm, the closer the effect is better. Wireless charging technology has been moving only with "small" mobile phones and small-size tabletsDevice dependent. However, A4WP (" Wireless Charging Alliance "), one of the three major wireless charging camps, recently announced that its technical standards have been upgraded, and the charging power supported has increased to 50 watts, which means that high-power devices such as laptops and tablets can also achieve wireless charging.
The core magnetic resonance medium and long distance wireless charging developed by Spurotin can successfully achieve wireless charging within one meter.
At present, the main wireless charging standards in the consumer field include the three major standards of the wireless Charging Alliance Qi, 4AWP and PMA. From the market size point of view, Qi is undoubtedlyCurrently the most popular, Qi's latest standard can achieve a wireless charging distance of 7 to 45 mm, which is a small breakthrough. A4WP's wireless charging technology, called "Rezence", uses resonant coupling technology, and although it has occasionally appeared at some consumer electronics shows, it has not yet been officially commercialized.
The following series introduces the different models and performance of TOTU car chargers. Item number: Ling Zhi Series - Car charging Car charging appearance level is very high, black materialThe surface texture is also great, the charging speed has reached the expected effect, there is no heat, and it is still very reliable after 2 hours of warm charging. It is not only suitable for car use, but also can be used in ordinary times.
Finally is Yingcaixing 108B, put on the car to use easily, and voltage display, fully functional, support mobile qc0 fast charge, can also output AC, put in the car can take into account multiple electrical products, notebook printer can be used, no noise, beautiful appearance, one USB support multiple protocol fast charge, the other support intelligent charge, Effectively improve the charging efficiency.
Can be bought newOr try to save it according to the following way: The reasons for the charger and charging line may be due to the fact that we do not have a good use habit in daily use, resulting in serious damage to the charging line, serious bare wear of the charging line, and therefore can not continue to use. Of course, there is also a case: the charging cable skin is not abnormal, the internal charging line is broken, in this case, we also need to replace the charging line to charge the phone.
How about TOTU car charger Item number: Lingzhi series - Car charger The appearance level of car charger is very high, the surface texture of black material is also great, and then as a charging device, the charging speed has reached myThe expected effect is really fast, and there is no fever, and it is warm for 2 hours, which is still very reliable.
TOTU charge fast and good, the line is not hot, the appearance and feel are very good, the car charge is also very good quality, three charging ports can be charged at the same time, and no matter what type of mobile phone can be charged, the brightness is soft when used at night, the light does not sting the eyes, the heat dissipation is also barbar drop, very safe, no longer afraid of the mobile phone will run out of power.
The power choice of millet car charge has a significant impact on the charging speed: the comparison between ten watts and twenty watts is particularly obvious, and the most important difference is the increase in charging speed. Twenty watts of charging power compared to ten watts, has a significant advantage, it can provide services for electric vehicles at a faster speed, significantly improve the charging efficiency, and bring great convenience to users.
The most intuitive difference is the difference in power, the power of one car is 10 watts, the power of another car is 20 watts, which also leads to the difference in its charging speed, 20w wireless car charging speed is much faster than 10w. The appearance of the car charger is different, the front panel ring indicator of the 10w wireless car charger is replaced with a blue indicator, and there is no on-board charger.
Xiaomi car charging 10 watts and 20 watts of charging, the biggest difference is that the charging speed is not the same. 20 watts can charge faster than 10 watts.
