I got it in a white box with some specification on it.

DSC_8553

The box contained the charger, instruction sheet in Chinese and mains plug.

Just below the Mi logo is a white led behind the plastic, it is not very bright.

Measurements


  • Power consumption when idle is 0.25 watt at 230VAC
  • USB output: 4×2.4A, but total limited to 4.8A
  • PD modes: 5V 3A, 9V 2A, 12V 1.5A
  • QC modes: 5V 3A, 9V 2A, 12V 1.5A
  • Default state for usb PD output is off.
  • Standard USB output is auto coding with DCP and Apple 2.4A
  • The two first standard ports also support Samsung.
  • QC port is also auto coding with DCP, Apple 2.A, QC3, Huwei-FCP, Samsung-AFC
  • PD has a Apple 2.1A coding.
  • Minimum QC3 voltage is 3.65V
  • The normal usb outputs share the minus connection.
  • QC & PD share one mains transformer.


Mi%20CDQ06ZM%20%233%20230V%20load%20sweep

Each port has individual overload protection that limits the current to about 2.7A, this is fine for a 2.4A port.

Mi%20CDQ06ZM%20%233-6%20230V%20load%20sweep

Running all four normal usb ports in parallel can deliver up to 5.6A, the rating says 4.8A

Mi%20CDQ06ZM%20QC5V%20230V%20load%20sweep

Quick charge at 5 volt can deliver 3.4A, this is fine for a 3A rating.

Mi%20CDQ06ZM%20QC9V%20230V%20load%20sweep

At 9V it can deliver 2.3A

Mi%20CDQ06ZM%20QC12V%20230V%20load%20sweep

And 1.8A at 12V, all a bit above the rated current, but never too much above.

Mi%20CDQ06ZM%20PD5V%20230V%20load%20sweep

USB-C Power delivery (PD) can deliver 3.5A at 5V, it is rated for 3A and it has cable compensation.

Mi%20CDQ06ZM%20PD9V%20230V%20load%20sweep

At 9V the current is 2.3A

Mi%20CDQ06ZM%20PD12V%20230V%20load%20sweep

And 1.7A at 12V, again a bit over rated current, but not too much.

Mi%20CDQ06ZM%20230V%20load%20sweep

Running all outputs at the same time, they first trip a bit above rated current. All 3 outputs are tracking and reach 1.5A/1.5A/4.8A at the same time.

Mi%20CDQ06ZM%20120V%20load%20sweep

Output power is the same at 120VAC

Mi%20CDQ06ZM%20230V%20load%20test

Running at 12V 1.5A, 12V 1.5A and 5V 4.8A (i.e. rated power) at the same time for one hour is no problem.
The temperature photos below are taken between 30 minutes and 60 minutes into the one hour test.

Temp5427

M1: 57.4°C, M2: 56.1°C, M3: 50.7°C, M4: 57.4°C, HS1: 61.5°C
Due to the internal heatsink the temperature is fairly uniform on the backside, but the QC+PD output is the highest power and is warmer.

Temp5429

M1: 46.5°C, HS1: 61.5°C

Temp5430

M1: 63.3°C, HS1: 77.7°C
There is no internal heatsink on this side and the two transformers are much more visible, M1 is 24W output for normal usb and HS1 is 36W output for PD+QC, the transformer must handle even more, due to the less than 100% efficiency of the secondary switchers, but there is basically no heat signature from them.

Temp5428

M1: 49.5°C, HS1: 60.1°C

Tear down

DSC_9112

I had to cut the back off to open it.

DSC_9113

When the back panel was cut all the way around I could remove it and pull the circuit board out.

DSC_9114

At the mains input is a fuse (F1) and a inrush current limiter (NTC1), this supply only has one common mode coil. There is two mains transformers, one for the 4 normal usb outputs and one for the PD ans QC outputs, near each transformer is two safety capacitors (CY1..CY4). Near the PD and QC output is two inductors for the switchers and a PD controller (U200: WT6615F)


DSC_9117

DSC_9118 DSC_9120

DSC_9119

DSC_9115

The other side of the circuit board is covered in a shield, it is connected to mains!
The black circle with a hole is for the indicator led.

DSC_9116

DSC_9122

I had to unsolder the shield before I could remove it. All the white spots are device that gets warm and need a heatsink, two of them need it so much that there is holes in the black isolation layer for them (It is the mains switching transistors).

DSC_9123

DSC_9124

DSC_9125

I used some time to remove the white stuff, making it possible to see the chips.
There are two bridge rectifier used in parallel (BD1 & BD2). Before each transformer is a switcher controller (U1 & U2) and switcher transistor (Q1 & Q2), they use the same controller but different transistors. There is also a temperature sensor near each controller (NTC2 & NTC3), probably to shut down the switcher if it gets too hot. On the low volt side is a synchronous rectifier transistor (Q51 & Q52) and controller (U51 & U52). The normal usb outputs then goes to the 4 usb connectors with a usb coding and current limiting chip (U55, U56, U57, U58) for each port, the chip and circuit about it looks the same for all four ports, I wonder why I got different results when testing.
The QC output uses a synchronous buck regulator (U53: SC8001) with two external transistors (Q53 & Q??) and a small QC/auto coding chip (U59: FT4) that supports a lot of protocols.
The PD output is similar with synchronous buck regulator (U54: SC8001) and two external transistors. The PD controller is on the other side, on this side is a mosfet (Q200) to turn usb-c on/off.

DSC_9126

DSC_9127

The distance between mains and low volt side looks fine.


Testing with 2830 volt and 4242 volt between mains and low volt side, did not show any safety problems.



Conclusion

This charger is not a really high power charger compared to the number of ports, but for most cases it has enough power for phones and tablets. It supports many different standards, including QC and usb-c PD with many different voltages, making it a very universal charger. Output noise is low and safety looks good.

I will call this a very good usb power supply.

Looks great. Depending on price, I might get one.

So when using both the Orange and single White port, you’ll still only receive 4.8A max combined?

The four white usb ports are one circuit and can deliver up to 4.8A, the orange and ucb-c is another circuit with its own power limit.

I going to pick one of these up! They are on Gearbest…

Thanks for the review.
