I am very pleased to apply for a new upgrade of the small steel hammer car charger (including QC3.0 fast charge) product evaluation. In recent months, I have been using a 2-port cradle with a display battery voltage and USB output voltage and current. Because of the battery voltage and so on, basically I am quite satisfied with it, you can always know the voltage of the car battery. Because of the lack of voltage and current display, the small steel hammer car charger was originally put into the cold palace (glove box) for use after the test was finished, but after testing, I finally decided to correct it and occupy the car for a long time. The only cigarette lighter charging port.
First, packaging and appearance
The small steel hammer car is packed with a simple outer box, and the outer packaging is printed with a lot of instructions. It is quite good, but unfortunately there is no simple explanation of how to use the safety hammer.
On the left is a small steel hammer car charger, which is much larger than the ordinary car charger. On the right is my commonly used 2USB car charger with voltage and current indication.
The function indicators are straightforward, support QC3.0 fast charge, 3.6V-6.5V/3A, 6.5V-9V/2A, 9V-12V/1.5A; dual USB fast charge-air purification-alloy striker broken window; negative ion concentration 2 ×10 6/cm 3.
FCC, CE certification, input 12V-24V output 5V/2.4A; push-type broken window car charger.
Broken window experimental glass
Second, broken window experiment description
I am dull, I have not been able to find how to use the broken window function. There is no introduction on the website. The box is prompted to scan the code to obtain the electronic manual. However, after the WeChat scan code, only the public number of Yuanchuang Technology is added, and no instructions on how to use the broken window can be found.
I think it is necessary to teach how to use the window breaker in the simplest and most direct way. The video presentation is the quickest way to teach, but unfortunately I didn't find it. Also, I personally recommend printing (or engraving) a simple instructions on the small steel hammer car charger housing, which is very important. After all, the car is not necessarily the one I have been using. I can't teach the car every time. This car charger is still a window breaker. How to use it when you need to remove the glass.
Since I couldn't find the instructions, I tried several methods, pressed the two springs on both sides, screwed the charging head, and pressed the top metal head by hand (very dangerous, but nothing happened)..., no success. Finally decided to try it directly on the glass. Since there are no relevant instructions and warnings (tips), I will take the glass out of the plastic bag directly. (Other users of the evaluation are very smart, the glass continues to be placed in the plastic bag, so it can't splash out). Of course, I did it with security measures. I used a box with edges to prevent the glass from splashing too far, and I took a 3M polycarbon splash-proof mirror.
The first time I failed, because I didn't use the instructions, I don't know how to use it. I can only estimate whether it is the first time to press the bullets like a child's pistol first, and then press a release switch to pop the striker. As a result, the press was found to be pressed to a certain extent, and the striker popped up by itself. Since the box was initially padded on the thick grass and the hand was not compacted, the striker just hit a small white hole on the glass.
The second time I explored, the box changed a place and placed it on a flat ground. The car tried to press it on the glass again. With a bang, the glass was broken. I didn't have any thoughts, and I didn't have time to video.
In this way, the glass is broken. I only had time to use my camera to make up a photo of the experimental glass. The picture shows that the tempered glass burst is still quite far.
The final conclusion is that the use of the push-type window breaker is to grasp it and press it hard on the glass until it hits the needle and slams it into the glass.
