Car charger seems to have become a must-have car products, recently the editorial department has a small number of colleagues to feedback: the new car to buy a full charge in a week after the discovery of a slow charge. You know, if not qualified to buy a car charger, charging too slow, not only will not charge, charging temperature and other conditions, will even cause on the circuit of the automobile, the more serious is the product itself, there may be an explosion and spontaneous combustion. And this is not alarmist.

For the business platform and the car charger a superb collection of beautiful things on the market, a few days ago "weekly quality report" has just conducted a sampling of the results showed that the unqualified products share is very high, it is worrying, as the owner, how should we these unqualified car charger discrimination? And how to choose and use the car charger? Do not worry, the following official website Xiaobian for everyone to answer.
Which I price range of the most serious failure.
Xiao Bian in a treasure on the search for car charger as keywords related products, according to the sales ranking in the top 10 in the average price of 27 yuan, with an average monthly sales of about 7000, visible high heat. However, the car charger is not bulky electronic products, so there are not many well-known brands, mostly Jerry, and if you buy a poor quality product is likely to have security risks.
But it is found that the risk monitoring, "the price in the car charger 20 yuan a total of 7 batches of samples, testing found that these are not qualified, unqualified rate was 100%; the price ranging from 20 yuan to 40 yuan between a total of 9 batches of samples, of which 7 batches do not meet the requirements of industry standards, not qualified the rate is still as high as 77%; and in the price of 40 yuan higher than the 4 batches of products, only 1 batches failed, a failure rate of 25%.
Terror, substandard car charger may direct explosion.
A small car charger can explode or ignite is really amazing, found in the inspection, there are security risks of the project focused on the lack of protection device, shell, flame retardant, overvoltage strength failed, and the normal temperature under temperature exceed the standard.
However, the carrying capacity will identify the product on the existing capacity virtual target problem, if this car charger if the load capacity is too low, at the same time for multiple devices charging, charger will cause excessive load, the charged mobile phone and other equipment may be in danger of explosion.
For those with a strong ability to carry the car charger, in this period, the weekly quality report, the engineer pointed out that it is necessary to focus on its normal temperature rise project is compliance. "If the car charger and drives a plurality of external devices, it will be a relatively large power capacity, and is affected by the temperature inside the car cigarette lighter, higher cooling channel is single factor, there will be excessive temperature rise of the car charger."
Is the metal material filled with a plastic car full?
n the flame retardant car charger shell to the metal shell, relatively safe, than plastic shell of course, no matter what material, car charger shell must meet the flame retardant requirements, if the components inside car charger short-circuit or other fault, there may be the risk barrier inside the product.
However, this can not be said that the metal material of the car must be filled with plastic car better, because no matter what kind of material charge, but also need to look at its structural design. For example, some metal materials of the car charge, in the design will be very close to the anode and cathode, it is easy to occur in the short circuit of the positive and negative, causing the power supply system of the short circuit fault risk.
The importance of internal structure
Internal structure, we need to see whether the product is equipped with protective devices and the internal structure of the design is reasonable, there will be a certain impact on the safety of the vehicle circuit. The internal structure of the design of the protection device, when the car charging circuit part of the exception, the fuse will fuse, to avoid greater losses.
How to select and use the car charger
In the purchase and use of car charger, should avoid very small volume of the product (there are a lot of this kind of charger will be sent to the gift), such a small volume of products often do not have a protective device.
Second, if you are not sure whether the car carrying capacity of vacuity, try not to blindly pursue high current and charging rate of products, use the car charger, if at the same time filling a plurality of electronic devices, also to observe the temperature of it, to avoid too large current caused by line fault.
In the use of car charger, as far as possible to start the vehicle, and then insert the car charge, after the vehicle flameout and the use of the end, it is recommended to pull out, especially in hot weather, to avoid overheating.
