Master brother measured 4 different brands of car chargers
Let everyone see what they have advantages and disadvantages
(Tips: this article does not have any sponsors ~)
Unit price comparison:
Domestic big brand bull, 33 wattS PD double mouth fast charge.
International big name Dr SC208, 45 watt double mouth fast charge.
A treasure sales of the first telecommunications, 30 watts double mouth fast charging.
A sonic boom model Qinmao, 100 watts double mouth fast charging.
First, the fast charging protocol and output power comparison.
bull:
It supports mainstream fast charging protocol ports such as Apple, Huawei, Xiaomi, Samsung, and vivo.
The maximum power output of the single port is 33 watts, and the simultaneous output of the dual port is 5V/2.4A, which is a total of 24 watts.
doctor:
It supports fast charging protocols for mainstream brands such as Apple, Xiaomi, Huawei, and Samsung.
The maximum output of a single port is 45 watts, and the maximum output of a double port is a total of 25 watts.
Telecommunications:
It also supports the fast charging protocol of huawei, xiaomi, apple, oppo, vivo and other mainstream brand mobile phones.
The maximum output of the single port is 30 watts, and the maximum output of the double port is 25 watts.
Qinmao:
It is also a fast charging protocol that supports mainstream brands such as Huawei, oppo, Samsung, and Apple.
The maximum output of the single port is 50 watts, but it is known that the dual port can output 10V/5A at the same time, that is, the dual port can output 100 watts of power at the same time. The highest nominal power among the 4 tested products!
Second, the single port charging speed and working temperature comparison.
I chose a cloudy and sunny place to keep the vehicle idle at a steady idle speed for this test.
I will use these four car chargers separately to charge the oppo find x3 that supports up to 65 watts of charging power from 50% of the battery for 15 minutes.
Then I took the thermal imaging temperature measuring instrument, fixed it 50 cm away from the charging head, and measured the temperature all the way, and recorded the maximum temperature.
The initial temperature of the charging head is 22.6 ° C, after charging for 15 minutes, the temperature of the charging head rises to 29 ° C, and the power of the mobile phone is charged to 65%.
I would like to add here that this thermal imager has high and low temperature tracking, so I only need to read the maximum temperature tracked by this measuring instrument.
The initial temperature of the charging head is 24.3 ° C, after charging for 15 minutes, the charging head temperature rises to 31.5 ° C, and the mobile phone charge is also charged to 65%. Same as a bull charging head.
The initial temperature of the charging head is 26.3 ° C, after charging for 15 minutes, the charging head temperature rises to 34.1 ° C, and the mobile phone charge is only charged to 58%.
The initial temperature of the charging head is 27.9 ° C, and after charging for 15 minutes, the charging head temperature rises to 47.4 ° C, which is the highest temperature measured at present. The phone's battery charge has reached 81%, and this charging speed is really surprising to me!
conclusion:
The fastest charging speed is the Qinmao charging head, which fills 31% of the power in 15 minutes. But its temperature has also risen a little hot...
The key is that this is still the position where the vehicle is protected from light, and the charging temperature in the case of idle speed rises, and if the car runs up, the temperature should be higher. So it's still a bit dangerous.
The charging speed is generally the bull and the doctor's charging head, their charging speed is similar, but the doctor's temperature rises slightly higher than the bull.
The slowest charging speed is a treasure Top1 telecom charging head, not only that, its temperature rises even higher than the Doctor!
Third, the two mobile phones charging speed comparison at the same time.
I use these 4 car chargers respectively, in the case of stable idle speed of the vehicle, at the same time to the iPhone11 and oppo find x3 charging, Apple's charging line for the original PD fast charging line and iPhone11 original line, oppo is also the original line.
Each time I tested both phones with an initial charge of 30% and a target charge of 40%, I would use the phone to time and record, and finally compare the total time of these 4 chargers.
The iPhone charged from 30% to 40%, a total of 10 minutes and 26 seconds, while the oppo charged from 30% to 40%, taking 13 minutes and 38 seconds.
This means that when the bull charger charges two devices at the same time, it is equally divided into total power, while the iPhone's battery will reach 40% faster because of its relatively small capacity.
The iPhone is charged from 30% to 40%, a total of 9 minutes and 34 seconds, while the oppo is charged from 30% to 40%, taking 13 minutes and 38 seconds.
The iPhone is charged from 30% to 40%, a total of 5 minutes and 55 seconds, while the oppo is charged from 30% to 40%, taking 12 minutes and 43 seconds, which is currently the fastest charging speed in the test.
This charger is a bit special, when the plug was just plugged in, the iPhone just flashed the charging icon, and then it didn't charge. But oppo shows a fast charging mode.
Fortunately, I asked the customer service of this charger, she said that it is because this charger is a double fifty watt high-power vertical charger, if the two devices are not the same voltage, will give priority to the high voltage of this device charged first.
This time, the oppo was charged from 30% to 40%, a total of 4 minutes and 52 seconds, while the iPhone charged from 30% to 40%, taking 13 minutes and 30 seconds.
The fastest dual-port charging speed is Telecommunications, which took only 12 minutes and 43 seconds to charge two mobile phones.
Followed by the Bull and the Doctor, it takes 13.38 seconds to charge both phones, but probably because the Doctor's power is slightly greater than the Bull, so it charges the iPhone slightly faster than the Bull by about a minute.
The worst is Qinmao, it has no way to charge two different mobile phones at the same time, and it also has a drawback, that is, it is 2 USB interfaces, so it has no way to use Apple's PD fast charging cable, which is also one of the reasons why it has a slow test time in this round.
Fourth, the overall texture contrast.
This is my personal subjective conclusion, for your reference only!
First of all, the quality, these 4 products are still much stronger than the plastic miscellaneous charger of twenty or thirty dollars on the market.
Very cheap car charger, I recommend that you do not use, one is because plastic is easy to high temperature will be more dangerous, the other is because the bargain in the mobile phone while navigating while charging is not charged.
And these four products I have tested with navigation before, and can be charged while navigating.
Then there's the exterior design, the bull's exterior design is my personal favorite, its entire fuselage is a fully integrated streamlined shape, and it is all metal, and it is also very comfortable to touch.
The doctor's color looks the best, the dark green matte metallic paint with bright metal trim, inserted in the car is actually a certain sense of high-grade.
The appearance of Telecommunications is a bit old-fashioned, but it has a very bright function, that is, after it is plugged into the car, it can display the voltage of the current vehicle.
Qinmao design is very moderate, there are not too many highlights, but it is the highest power and most practical.
The above is my evaluation of these 4 car cigarette lighter charging heads, I hope to help everyone ~
