multi usb wall charger

2019-07-13

According to incomplete statistics, China's car ownership accounts for 20% of the world's total, while sales account for 30% of the world. China's cars have exceeded 200 million, and it is still increasing.
Although the number of cars is increasing, but the car as one of the heavy assets, the update iteration speed can not reach the same as electronic products. Nowadays, smart phones and even human hands plus driving recorders, car vacuum cleaners and other equipment, it can be said that many owners now There is a problem with insufficient power supply in the car.
At this time, an excellent extended car charger can solve many of your problems, such as one-to-three extended car USB charger. Some small partners may think that many new cars are not equipped with a USB charging interface. Why do you need to purchase additional car chargers?
In fact, the USB interface of the new car is not born for the charging function. They are more for transmitting audio/video signals. If the load is large, the power of the USB interface is not enough. The interface has become the best choice for us to expand the power supply interface.
 
One-to-three extended car USB charger adopts an integrated injection molding design, and the product has no slotted nozzle. The upper boundary is made of aluminum alloy and treated with a matte finish.
The overall appearance is round and exquisite, the shape of the curved shape transitions smoothly, has a very good feel, whether it is visual or touch, the entire car charger has a very strong sense of unity.
 
 
One to three extended car USB chargers can expand two USB charging ports and one power interface, one for three extended solutions, one by one.
The contacts are made of manganese steel, which is resistant to wear and is not easy to loosen. When the power is turned on, there is a blue light bar as a reminder. If the car is dark or even at night, it can give a good hint effect.
Performance parameter analysis Multiple security protection, can carry multiple devices simultaneously
 
 
One to three extended car USB chargers use dual USB split + power interface expansion design, single port maximum output 2.4A, output total power 100W, fast and stable charging.
In addition, driving recorders, navigators, car purifiers, etc. can also be used with charging. It is compatible with 12-24V wide-amplitude voltage and is compatible with all kinds of mainstream models. It also has built-in precision chips to resist transient surges and is compatible with a wide range of devices.
 
 
 
 
In addition, the USB interface has a five-fold protection design, overvoltage protection, overcurrent protection, anti-static protection, short-circuit protection and surge protection.
In addition, the design of the expansion port security cover is as far as possible to avoid the charging safety hazard (note that the expansion port can not be inserted into the cigarette lighter), multi-port output, and even the expansion interface can also be connected to a car charger device.
Charging performance test
Although we mentioned the performance of the charger in the past, it is only an official label, but it is actually a simple test by physical.
 
 
 
 
One to three extended car USB chargers support a maximum of 5V/2.4A charging. In the actual test process, it is often difficult to reach the officially declared value due to the difference between the rated current limit of the mobile phone and the residual current.
Android mobile phone test value is 9.76W (5.143V/1.897A), and test Apple mobile phone charging has 9.14W (5.14V/1.77A) high-power charging, compared to a few hundred pieces can only buy one Apple ancestral 5W charger It’s not too good.
In terms of dual output, when facing two high-current devices at the same time, a total of nearly 18W output can be provided, which is in line with the officially rated maximum power value of 5V/3.6W.
It is worth mentioning that the two interfaces are indeed in the same order as the official ones, and can recognize digital products such as Android/Apple and even charging treasure, and automatically allocate the reasonable current output value of each interface.
