With more and more electronic devices in everyone's hands, the supporting chargers are also increasing, every time you buy a mobile phone or computer will bring an original charger, the number of time is longer, the socket is not enough, the backpack is heavier when you go out, so everyone is looking for a good solution.
There are more devices, more original chargers, what if you want to reduce the burden of the charger? One is a multi-port charger (currently mainstream); the other is directly not sent (yes, it's you, Apple). So now multi-port chargers have become the main choice of users, especially multi-port, high-power, gallium nitride, compact chargers.
The emergence of wireless charging is convenient for users to use, and only need to put the mobile phone on the table, eliminating the operation of plugging and unplugging cables.
Here is a question for everyone, how many of you who are using wireless chargers are used under the above conditions. In a multi-port charger, use one interface to connect to the wireless charger and the other interface to charge other devices.
Just want to think about something different
In the continuous development of multi-port high-power gallium nitride chargers, there are also problems, such as interface fights, power allocation, and protocol fights, which is also a "side effect", after all, compared to convenience, these small problems can still be overcome. However, there are also some chemical reactions in the middle, such as in the multi-port charger, whether the no load of an interface will affect the power use of the other interface, which we have tested, and the details can be stamped here. Will the data cable also be unloaded? The multi-port charger plugs in this data cable motorcycle to change the bicycle
Today's content is to solve the feedback of readers, and it is also an advanced version. Then in the previous article, the interface is plugged in with a line no load to an interface connected to the wireless charger no load to see if it will affect the power use of other interfaces (in fact, the author also wants to know). The test randomly selected some chargers and wireless chargers, and the choice of chargers was selected according to the interface configuration of the four current mainstream multi-port chargers of 1C1A, 2C, 2C1A and 3C1A.
Nubia White 65W Gallium Nitride Charger
First of all, let's take a look at the dual C interface configuration, the object of this selection is the Nubia White Dual USB-C 65W Gallium Nitride Charger, nubian White 65W Gallium Nitride charger supports 65W fast charging in single-port output, and will become a 45W+18W output strategy when multi-port simultaneous output.
Use a C port to connect the Apple MagSafe magnetic wireless charger no load, use another C port to charge the laptop, the actual charging power is about 44W, and the C port of the no-load wireless charger is at 9V output voltage, but there is no output power, which shows that there is indeed an impact.
Replace the Apple MagSafe magnetic wireless charger with the Xiaomi Sailing Wireless Charger, other conditions remain unchanged, it can be seen that it will still affect the power output of the charger.
Xiaomi Mi 65W Gallium Nitride Charger 1C1A
The 1C1A interface version chose the Xiaomi Mi 65W Gallium Nitride charger 1C1A as a representative, and the Xiaomi Mi 65W Gallium Nitride Charger 1C1A supports 65W fast charging when USB-C is output alone, and the power distribution principle of 45W+18W will be followed when the dual port is output at the same time.
Connect the USB-A interface of the charger to the Xiaomi Sailing Ship Wireless Charger no load, and the USB-C interface of the charger to charge the laptop, at this time the USB-C output about 44W of power. It can be seen that when USB-A is connected to wireless charging, the power output of the USB-C interface will indeed be affected.
Under the same conditions, using USB-C to connect Apple MagSafe magnetic wireless charger is empty, using the USB-A of the charger to charge the Xiaomi Mi 11 Pro, the actual measured output power of USB-A is about 16W, and the output of USB-A is not affected at this time.
Greenlink 65W Gallium Nitride charger
The 2C1A interface version here selects the Greenlink 65W Gallium Nitride charger as a representative, the USB-C of the Greenlink 65W Gallium Nitride charger supports 65W fast charging when it is output separately, and the power distribution principle of 45W+18W will be followed when 2 USB-C are output at the same time.
Use USB-C to connect apple MagSafe magnetic wireless charger no load, use another USB-C to charge the laptop, the output power is around 63W. The measured maximum output power of USB-C is not affected.
Under the same conditions, the Apple MagSafe magnetic wireless charger is replaced by the Xiaomi Sailing Wireless Charger, and the power received by the computer is about 63W, which is actually not affected.
MOMAX 100W Gallium Nitride Charger
Finally, let's take a look at the 3C1A interface version of the 100W Gallium Nitride charger, the object of this choice is the MOMAX 100W Gallium Nitride charger, the USB-C of the charger supports 100W fast charge output when the output is separate, and the power will be intelligently allocated when the dual USB-C or 3 USB-C outputs are simultaneously made to make the total power 100W.
Use USB-C to connect the wireless charger no load and use another USB-C to charge the laptop. At this time, the charging power of the laptop is about 44W, and the actual measurement will be affected.
Replacing the wireless charger with the Apple MagSafe magnetic wireless charger under the same conditions, as shown in the figure, will indeed be affected.
Charging head net summary
The above tested for everyone 1C1A, 2C1A, 2C and 3C1A four interface versions of the charger in the wireless charger no load, the output of other interfaces will be affected, here the charger is randomly selected, but for different interface versions.
The actual test found that there will indeed be an impact, the charger is no loaded in the connection wireless charger, and the output power of other interfaces will be affected, which will make the charger determine that it is a dual-port output state at this time.
However, at present, there are many chargers with four interface versions on the market, and this time it is impossible to test one by one, not to say that all multi-port chargers connected to wireless chargers have occupied power, and the author also holds the mentality of exploration to test. If you have a friend who is also in this state of use, and there happens to be a POWER-Z tester around you, you may wish to take a look at the power situation.
