At the launch of domestic mobile phone manufacturers, there are always some spaces to accessories, especially charging accessories, which are often “fully armed”, from chargers, wireless charging, mobile power to vehicle chargers, which are very complete. The manufacturers earlier realized that the scene of the scene was charging.

As a creative digital brand, Benks Bangkos launched a 30W high -power car charging, the classic matching of 1A1C interface, pocket volume, strong performance, cool appearance. Not only can it be a fast charging for iPhone and iPad, most Android phones can be charged fast. Even due to multiple positions voltage, some notebooks can also be charged emergency. Let’s take a look at this product together!

1. Open the box

The skin of the tree, the face of the human, and the appearance of the product, and the packaging are the same thing, belonging to the first ring of the “interlocking”.


1. Open the box

The Benks car is different from the tradition on the packaging. I have made new ideas. Let’s take a look.


Benks 30W 1A1C Mini car is very small and light, and product packaging also focuses on highlighting this feature. How can it be? It is so simple to charge the car on the card. So you can’t see the traditional box packaging, there is only one card, a card like a business card.

The front is pure black, the name is printed, and it is a car charging in the middle. You can see it directly through the shell. This packaging is OK.

Behind the parameters, it seems that the packaging is indeed the “business card” of the product. The excerpts are as follows:

The car charging is also very simple and humane. In the preset area behind the card, you can open the package and take out the car charging.

2, appearance display

Benks 30W 1A1C Mini car is a small highlight, which is small, how small is it?

Between you, the same size as the thumb,

Put in the palm, light and small. It is, so, compact!

The car charging adopts two -stage design, which is distributed in a staircase as a whole. The side is straight, and the surface anode oxidation treatment has a slight matte texture, and a logo with “BENKS” is printed on one side.

The other side is printed with parameters, and the excerpts are as follows:


MINI hand -carried car charger

USB-A Output: 4.5V5A / 5V4.5A / 9V3A / 12V2.5A

USB-C Output: 5V2.4A / 9V3A / 12V2.5A / 15V2A / 20V1.5A


Total output: 30W

In order to be small and convenient to use, BNKS has set up a MINI car charging the active semicircular dual -pull ring structure. It needs to be used as a pull -ups to easily remove the car charging. The handle part can be folded and storage is flat on the shell. Usually, the ring is put down as part of the frame of the car. The size of the car is close to most car cigarette lighter slots. The hidden design does not occupy extra space at all.

The end surface of the car is made of PC, with a USB-C and a USB-A total two output interfaces. In addition, the end surface is also designed with a hidden atmosphere light.

After the car is charged, the atmosphere lights light.

3. Size and contrast

The thickest diameter of the car charging is about 20.62mm.


The maximum is about 39.94mm.

In the past, we compared the cross -sectional area of ​​the cross section of the car. This model was completely comparable. Compared with the side of the coin and the car, you can see that the coin is higher than the side.

The car is over 20g, which is very light.

2. Basic performance test

Digital products such as mobile phones and computers, the important consideration before buying lies in performance. The same is true of the charger. Basic properties such as power size and compatibility protocol constitute the basis of high -quality experience. Let’s take a look at the performance of BNKS 30W 1A1C Mini car charging.

1. Quick charge protocol detection

Use Power-Z KT002 to read the fast charging protocol of the USB-C interface, and actively support the fast charging protocols such as Apple2.4A, QC2.0, QC3.0, QC4+, AFC, FCP, SCP, PE, PD, and PPS.


Reading PDO packets, support 5V2.4A, 9V3A, 12V2.5A, 15V2A, 20V1.5A five fixed voltage gears, as well as a set of PPS gears of 3.3-11V 3A.

Read the fast charging protocol of the car charging USB-A interface, and the actual test supports Apple2.4A, QC2.0, QC3.0, AFC, FCP, SCP, PE and other fast charge protocols.


2. USB-C charging compatibility test

The fast charging protocol of this car charging USB-C interface is very rich. How compatible with the product?

I want to see a representative, using the USB-C interface to use the car charging to charge iPad Air4 with a power of about 28.4W, which is really good.

For all the test data assembly forms, Apple devices are in PD fast charge state, and the Xiaomi family compatibility is good. Nubia Red Devils 5G, Samsung S20 Ultra, Black Shark 3s are in PPS fast charging state, and the overall performance is very good. Essence

From the pillar map, the top equipment is mostly models such as iPad and Xiaomi 11, Black Shark 3S, OnePlus 8T, Nubia Red Devils 5G, Meizu 17 Pro, Samsung S20 Ultra followed, and then It is the iPhone12 series.


3. USB-A charging compatibility test

In the USB-C link, Huawei’s two flagship performances are average, but in the USB-A test session, Huawei is “male”. The power of Huawei P40 Pro can reach about 22W, which is enough to supplement the power in a short time.


The summary of all the test data is made into a table, and Apple devices are in the Apple2.4A charging state. Huawei’s mobile phone successfully shakes hands with SCP fast charging, and Meizu’s models perform well.


Look at the pillar chart, the flagship of Meizu and Huawei in front, the flagships of OPPO and vivo are behind. This situation is classic in the USB-A interface compatibility test.


4. Output at the same time with both mouth

Use USB-C to charge iPad Pro 11 with a power of about 9.5W. At the same time, USB-A is used to charge Samsung S20U with a power of 8.9W.


Third, charging measurement

After the basic compatibility and fast charging protocol test, I believe that everyone has a certain understanding of the performance of the BENKS 30W 1A1C Mini car charging. Let’s test it in the “actual combat” below.

1. iPad Air4 charging the whole process


This car charges up to 30W and the iPhone 12 series rated 20W. The challenge is too low, so it is iPad. The USB-C interface using the car charging is charged for the iPad Air4 to see the change in the entire charging.


After a short -term boot time of iPad Air4, the power reaches the power gear of 15V 2A; the high power input lasted for about 45 minutes, and then the current and power began to decrease in step -level Until the end. The highest power is 14.92V 1.94A 28.99W.

The charging test data is made into a curve chart. The car charging is half an hour to charge 35%of the iPad Air4, and it is charged 66%of the power in 1 hour. The whole journey takes about 2 hours and 12 minutes, which is quite good.

2. Huawei P40 Pro charging the whole process


The USB-A interface of the car is marked with the FCP and SCP fast charge protocols that support Huawei, so we measure the entire process for Huawei’s flagship P40 Pro.

After a brief boot time of the P40 Pro, the power has reached a power gear of 4.5V 5A for a short period of time, which lasted about 5 minutes; then the current and power began to fall to 1 hour and 5 minutes; then the power decreased as the current gradually decreased. Until the end. The highest power is 4.67V 4.79A 22.39W. The entire charging process is indeed the taste of Huawei fast charging.


The car charging half an hour is 48%of the P40 Pro, 82%of the power in 1 hour, and the whole journey takes about 1 hour and 55 minutes.

3. Maximum output power


The maximum output power of the EB program -controlled electronic load test charger is used as a current in 0.1A as the current, 10 seconds is the time interval, and the maximum output of the car charging 20V gear was finally recorded at 18.8V 1.5A 28.2W.


Look at the 9V gear, the maximum is 29.7W.


4. One hour full load stability

According to the rated power 20V 1.5A 30W full load, the charger is tested for stability. The test time is one hour. The voltage value during the test process is horizontal, without obvious fluctuations, and the long -term full load is relatively stable.

5. Temperature test

This car charging is very small. Many readers are very concerned about the heat of nitrogen -nitride charger, so we add the temperature rise test, but we must first understand that a few warm -up test little knowledge is understood.

The calorie of the charger is related to power density, efficiency value, internal solution design, environmental temperature, and so on. Products with low power density have sufficient space to separate the component layout, but the surface temperature will be low, but the volume is often huge.

Products with high power density often adopt the design of vertical plug -in components in the interior. As much as possible, the charger is used as a small convenience for users to carry. Theoretically, the temperature will heat the product with low power density.

In addition, the single -port charger and multi -port charger are also different because the circuit design is different. The single -port charger belongs to the AC to DC direct output method. The multi -port charger is AC to DC to DC. The single -port charger will be higher.


Test the temperature rise of the charger. The test conditions are tested at a constant temperature of 20V 1.5A 30W full -load in a constant thermostatic box with a temperature of about 25 ° C for one hour. One hour later, the car charging with the “cigarette lighter” as a whole. At this time, the maximum temperature is 53.4 ° C. Compared with the ambient temperature, the temperature rise is about 28.4 ° C.


It should be noted that the metal has a good thermal conductivity, and the wire interface is generally high -connected with the car charging. In the previous temperature rise test, we try to avoid the temperature recorded to the interface position. The test of the car charging is more complicated, so in the figure above, it is calculated as a whole.

After removing the car charging from the “cigarette lighter”, observe immediately. At this time, the maximum temperature of the car charging is about 42.5 ° C. Compared with the ambient temperature, the temperature rise is about 17.5 ° C.

Let’s look at the interface position after removing the wire. At this time, the maximum temperature of the car is about 47.7 ° C. Compared with the environmental temperature, the temperature rise is about 22.7 ° C.

Winning test summary

The one -hour full -load temperature is used to test the fever of the charger under extreme use. In daily use, users rarely encounter this long -term full load. The power of digital equipment such as mobile phones, tablets, and charging treasures is not high, and the temperature rise will be more relaxed, while the notebook charging will gradually reduce the power with the battery, and the heat will be reduced simultaneously.


At present, the surface temperature requirements of the charger are not higher than 95 ° C. It may be due to the metal body and a good structure. BNKS 30W 1A1C Mini car has good control temperature control, and the test maximum temperature meets the standard.

Charging head network summary

In terms of appearance, the BNKS car is different from traditions on the packaging and made new ideas. The car is very small and light, and it is light and light in the palm. The car charging adopts two -stage design, which is distributed in a staircase as a whole. The side is straight, and the surface anode oxidation treatment has a slight matte texture. The thickest diameter of the car charging is about 20.62mm, the longest is about 39.94mm, and weighs about 20g.


In terms of performance, the two interfaces of the 1A1C of the car are very powerful. USB-C interface supports Apple2.4A, QC2.0, QC3.0, QC4+, AFC, FCP, SCP, PE, PD and PPS and other fast charge protocols. It has 5V2.4A, 9V3A, 12V2.5A, 15V2A, 20V1. 5A five fixed voltage gears and 3.3-11V 3A set of PPS gears. The fast charge protocol of the USB-A interface supports the fast charge protocols such as Apple2.4A, QC2.0, QC3.0, AFC, FCP, SCP, and PE.

The temperature control of the charger is particularly good. After a full load, the highest temperature is only about 28.4 ° C. It means that it has worked hard on the heat dissipation. Interested friends can see our disassembly about this car charging.

In general, the Benks 30W 1A1C Mini car is very careful in packaging and appearance. The highlight is that it is small and light, while maintaining a strong performance. Friends in need can try.
