I got it from HDfury.eu shop.

This is a usb charger, that with the help of a smartphone, can show current and voltage for all 3 outputs. This sound like it may be a smart idea.
But the specifications are a bit of nonsense, some of the data looks to cover only the MPU inside the charger and they are basically useless: Knowing the power consumption of the MPU in different modes, is not really useful when not knowing what modes are used and how much, a total power consumption from mains would be better anyway. That the MPU has 11 ADC channels, do not say anything about how many is used.

DSC_9542

I got it in a cardboard box with a very important cable outside the box.

DSC_9543

Inside the box was the power supply and a couple of mains adapters. No manual was supplied.

DSC_9544

The cable between the power supply and the phone. This uses the headphone jack on the phone to supply data on the microphone input (Remember that not all phones has this jack).

Application (Android)

Click on the images to get full size.

Screenshot_3

3 devices charging, each at 1A and 5 volt. The WATT label is not watt, but watt hours (Wh).

Screenshot_4

One device has finished charging, this is concluded from the power consumption.

Screenshot_5


Two devices finished and one output not connected.

Screenshot_9

Here I am using Quick Charge on the 3 output, the device is charged with 12V.

Screenshot_8

Overload, I tried charging two devices at 5V 1A and one device at 12V 1A, the power to the 12V device was shut down.

Screenshot_2

But everything is not fine, here I am drawing 1A, 0.2A and 0.5A. I tried it again at a later time, but there the result was not this bad.
The first channel has been drawing 1A all the time, but as can be seen on the curve the registered current jumps a bit up/down, depending on the load on the other channels.

The chart scale only goes to 2A on the display, this is slightly less in real life due to the errors.
The chart will be cleared when power goes into standby or the application is stopped for any reason.
Watt(Wh) and time is accumulated in the charger and will show correct when the application is started.



Measurements


  • Power consumption when idle is 0.14 watt
  • Usb output #1 is coded as no coding (The data pins are used for communicating with the phone).
  • Usb output #2 is coded as Apple 2.1A (There may be some auto coding, but I did not detect it).
  • Usb output #3 is coded as Quick Charge 2.0 and auto with Apple 2.1A as max.
  • Weight: 156g (without accessories)
  • Size: 89.8 × 81.8 × 54.4mm (EU plug)
  • Current resolution is about 0.02A, this fits fine with a 10bit ADC


CurrentLimits

A device must draw about 70mA before it will be registered and anything below about 120mA will report “Charging complete”.

CurrentMeasurement

Even when everything is working the current is not that precise.

VoltageMeasurement

Voltage measurement is also a bit off and fairly high when the device is unloaded.

Comm

The communication to the phone is done with audio tones (FSK). I did not see an obvious gab between messages, i.e. the tone must be on all the time.

Fury%20Universal%20PSU%20Doctor%20%231%20120V%20load%20sweep

Output #1 can deliver about 3.6A before overload protection kicks in. The output voltage drops significantly with load, this may be due to current sense resistors inside the supply.

Fury%20Universal%20PSU%20Doctor%20%231%20230V%20load%20sweep

There is not much difference between 120VAC and 230VAC supply.

Fury%20Universal%20PSU%20Doctor%20%232%20230V%20load%20sweep

The current limit on output #2 is at about 3.2A, I do not know why it turned the output off twice at the start.

Fury%20Universal%20PSU%20Doctor%20%233%20230V%20load%20sweep

Same with output #3 when run at 5V.

Fury%20Universal%20PSU%20Doctor%20%233%20QC9V%20230V%20load%20sweep

With QC at 9V the output is only about 1.6A

Fury%20Universal%20PSU%20Doctor%20%233%20QC12V%20230V%20load%20sweep

And down to about 1A at 12V.

Fury%20Universal%20PSU%20Doctor%20230V%20load%20test

No problems running one hour at 4.2A distributed on all 3 outputs.

Tear down

DSC_0082

Some directed pressure with my vice could crack it open.

DSC_0087

At the mains input is a fuse and a fairly large common mode coil. The switcher IC (U1: LNK6765E) is mounted on a heatsink. The safety capacitor (CY1) is mounted beside the transformer. Next to the capacitor is a filter inductor (L2) for the low voltage. The flat inductor (L3) is for the QC voltage adjustment. On the black heatsink is the rectifier diode (D1). Between the usb connectors are the indicator leds.

DSC_0088

The switcher is mounted with a clamp to a heatsink. The safety capacitor has a lot of approvals (as usual).

DSC_0089 DSC_0091

On the first picture the common mode coil is in front, on the second picture the usb connectors and the four leds (3 blue + one red) are in front.

DSC_0090

The heatsink for the rectifier diode is next to the input fuse.

DSC_0083

Part of this side is covered in isolation tape, that is the part above the mains input.

DSC_0084

With the tape removed the bridge rectifier (BD1) can be seen. The low volt side is much more interesting, let see how much I can find out.
The largest part is the MPU (U2: R5F102AAA). There is a QC controller (U8: CHY100D) and the switcher for QC (U12: marked PMOQ / 08W / Z02C) with two rectifier diodes (D5, D6)
Resistors for current sense (R14, R14, R18, R19, R36, R37: R200), two in parallel for each output.

And some guessing:
Maybe U10 (Marked: HEE / ZE) is switching between auto coding and QC.
Probably auto coding chips (U3, U6, U13: Marked BTW), I wonder if they are controlled by the microprocessor.
Maybe a switch (U4, U7, U11: marked GUU / 5NF / 12) to control output power.
(U9: marked JCB / 4S3 / E)

R5F102AAA: Renesas MPU with flash memory, RL78/G12 Data flash provided, 30pin, 16kB rom, consumer -40°C ~ 85°C

DSC_0086

Safety distance looks good.

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


Conclusion

A charger that can show current and voltage for each output is interesting and has been seen before, but with graphing, multiple outputs and quick charge this device is more versatile that anything I have seen before.
There can be some good economic in using a phone for display, instead of mounting the display in the charger. The phone uses a high-resolution display and today most people have one, but I am not really impressed with the connection used. Some phones are lacking the audio jack and the usb connection will increase resistance on that output. A Bluetooth module would be a more modern solution. The app. do also loose the chart way to easy, some way for the app. to stay in the background and continue collecting would have been nice (This may not be possible due to the usage of the audio jack).
The precision is not very good, an external usb meter is much more precise

The total current is a bit low for a 3 output device, there is a lot of noise and I am missing auto coding on the outputs, my phone will only charger with 0.6A. The output voltage starts rather high and drops significantly when loaded.


In total I am not that impressed with the charger, it is a fairly good charger, but the analyzing part fails.

So, it's good at charging, but not at the thing you're buying it for.

When this got introduces in the request thread, I had some thoughts about the way they're using a cable to transfer the data to the phone.
But even with a cable they can't keep a connection so it seems.

Thanks for the review, HKJ!!!
