Nowadays, people are more and more inseparable from portable digital devices. "Internet+electricity" is like having the world! No matter where you go, it is a crazy thing that the mobile phone is in short of power, so the battery life and charging have always been the concern of users. Whenever I find a charging place and hear the sound of "beep" to connect the power supply, my heart will be put down. Therefore, in the era of mobile Internet, people can't live without the power of equipment and the network. In this regard, the well-known hardware manufacturer ORICO has designed a 10U charging bus - DUK-10P for some public use scenarios such as coffee shops, parties, restaurants, airports, etc., to solve the problem of simultaneous charging by multiple people, and to optimize the wiring harness with a bracket to make the desktop look cleaner and simpler.

"Rechargeable bus", as its name implies, can carry multiple devices at the same time, The DUK-10P can meet the demand for parallel charging of 10 devices at the same time with its full fire, and each USB port can provide more 5V/2.4A output at the same time with a built-in intelligent identification IC. The total power can reach up to 120W, so today when fast charging is in the ascendant, there is no need to worry about the speed of multiple devices charging at the same time. It has a clear market positioning.

From the appearance, the "rechargeable bus" is relatively round, some of which are similar to the shape of the bread machine. The whole machine is made of PC+ABS flame retardant materials. The top of the machine is innovatively designed with 10 slots, and all of which are made of texture surface treatment to ensure the stability of equipment placement. The lower part of the machine body is made of pure white high gloss surface treatment. The overall style is simple, and the feel is very delicate.

The bracket has been rounded, so there is no need to worry about scratching the equipment. In addition, the concave surface treatment and reasonable depth at the bottom of the bracket, together with the lower center of gravity, make it stable to place both mobile phones and tablet devices, even if the iPad is placed, there is no need to worry about falling down.

There are 10 USB sockets on the side and a power indicator light. It is also very reasonable to have both sockets. There is no pressure when multiple USB charging lines are inserted side by side. With a total power of 120W, the full output of 5V/2.4A can be achieved, so the devices supporting fast charging will charge quickly, and there is no need to worry about limiting current when multiple devices are charging in parallel.

There are cooling holes at the bottom and side of the "charging bus". It is worth noting that the cooling holes at the bottom are equipped with fans for active cooling. The four high legs can not only prevent skidding, but also allow the air to flow well, so as to facilitate the smooth discharge of heat from the internal main board.

In the experience, when the three devices are charging at the same time, no body temperature can be felt. If the 10U port is output with full load at the same time, the strip heat sink on both sides and the active heat sink on the middle honeycomb will play a role, and the air duct circulation can be formed inside to control the temperature.

On the other side of the "charging bus" is the power switch and power input interface. The power input adopts a universal split three prong design, which is easy to carry. The 100V-240V wide voltage can be used in many countries as long as it is equipped with plugs of different specifications. As a mobile charging station, the "charging bus" has taken its portability into consideration at the beginning of design, so it has been optimized from the specification of accessories.

As a multi port charging device, the charging bus can not only adjust the current through the intelligent IC, but also provide a stable and continuous output. Therefore, when charging multiple devices, the built-in MPS synchronous rectification technology will play a stable role, which can not only reduce the overall loss of the charger and improve the conversion efficiency, It can also reduce the heat of the charger to ensure stability.

During the output test, the input voltage and current of the single plug-in 5V/1A device are basically the same as those of the original charger. The maximum 5V/2.4A output port is automatically identified and current limited to ensure the safety of the charging device.

Charging the Xiaomi 5s Plus 5V/2.5A mobile phone, the output voltage is 4.99V, and the current is 1.83A. Since the mobile phone will slowly enter the trickle charge after 70% of the power, the charging bus has no difference with the publicity in output. In addition, during the test, a previous USB charging line was used, because there was a short circuit in the damaged part of the charging line, and the charging bus also made a short circuit protection in time, which was excellent in safety.

When the other three devices are charged together, the output voltage of Xiaomi 5s Plus is still stable at 5V, and the current is 1.81A, which is 0.02A lower than that when charged separately, and can be ignored. It can be seen that the charging bus can still maintain the independent output of each U port when multiple devices are charged simultaneously, and the U ports do not affect each other, ensuring the charging efficiency.

Summary:

The original intention of ORICO DUK-10P design is more from the perspective of parallel charging in public places, but now it seems that more electronic products are used well in families. Although the unique and domineering shape occupies a space of the table, the design of multi rack really plays a good role in the process of multi device charging, Because the wire material is not uniform, it does not look beautiful. It is also suggested that the "rechargeable bus" should be designed with a thread trimmer; The main 10 port USB charging is really a good idea, which also meets the needs of most families and public places. It changes the current situation of insufficient sockets in many places. Smart IC chips and charging safety measures also fundamentally solve the problem of electricity safety, and multiple devices can still maintain a strong output when charging, It also allows the charging bus to effectively solve people's pain points; Although the current price of 699 yuan may exceed some people's expectations, in the long run, such a new multi port charging device still has room for development.
