Anker PowerPort Speed 5 2xQC3 A2054

DSC_9692

Official specifications: I got it from a amazon.de dealer: AnkerDirect DE

DSC_9484 DSC_9485

I got it in a cardboard box.

DSC_9684

The box included the charger, a mains cable, a welcome guide (Instruction sheet) and a adhesive strip to mount the charger somewhere.

Measurements

Anker%20PowerPort%20Speed%205%202xQC3%20A2054%20%231%20230V%20load%20sweep

The output has cable compensation and there is no individual port protection.

Anker%20PowerPort%20Speed%205%202xQC3%20A2054%20%233%20230V%20load%20sweep

This output looks the same.

Anker%20PowerPort%20Speed%205%202xQC3%20A2054%20%23123%20230V%20load%20sweep

Running all 3 2.4A output in parallel I can see the overload protection is at around 5.5A, this is a high current for a single usb port.

Anker%20PowerPort%20Speed%205%202xQC3%20A2054%20%235%20230V%20load%20sweep

At 5V the QC port can deliver about 3.5A (I did run this test on both QC port, they are very similar).

Anker%20PowerPort%20Speed%205%202xQC3%20A2054%20%235%20QC9V%20230V%20load%20sweep

This also holds at 9V

Anker%20PowerPort%20Speed%205%202xQC3%20A2054%20%235%20QC12V%20230V%20load%20sweep

And even at 12V

Anker%20PowerPort%20Speed%205%202xQC3%20A2054%20%235%20QC12V%20120V%20load%20sweep

Using 120VAC do not change it.

Anker%20PowerPort%20Speed%205%202xQC3%20A2054%20230V%20load%20test

For load test I did 5V 4.8A and 2x12V 1.5A
The temperature photos below are taken between 30 minutes and 60 minutes into the one hour test.

Temp5936

M1: 58.5C, M2: 51.6C, HS1: 60.3C
The heat profile matches the heatsink below (See tear-down). HS1 and M1 are the two transformers (HS1 is QC).

Temp5938

M1: 59.8C, M2: 54.5C, HS1: 61.2C (The "Barcode" is a fault from my camera or memory card, this is the only time I have seen it).

Temp5939

M1: 53.9C, HS1: 55.9C
HS1 is one of the mains switchers.

Temp5940

M1: 45.6C, HS1: 57.0C
Again HS1 is one of the mains switchers.

Temp5937

M1: 55.3C, HS1: 60.2C

10ohm

Noise at 0.5A load is: 15mV rms and 126mVpp.

5ohm

Noise at 1A load is: 14mV rms and 244mVpp.

2ohm

Noise at 2.5A load is: 12mV rms and 152mVpp.

1ohm

Noise at 5A load is: 14mV rms and 163mVpp.

10ohmQC5V

Noise at 0.5A QC load is: 4mV rms and 99mVpp.

2ohmQC5V

Noise at 2.5A QC load is: 10mV rms and 205mVpp.

10ohmQC12V

Noise at 12V 1.2A QC load is: 5mV rms and 118mVpp, all values are very low.



Tear down

DSC_1939

Some pressure with my vice and I could break the lid of with a screwdriver. The circuit board did not come loose, it is secured with a bit of glue.

DSC_1940

A bit more breaking and it was out, notice the white pads on the lid, they are to improve heat transfer.

DSC_1941

The transformers is very close to the top heatsink.

DSC_1944

And there is some heat transfer paste between transformer and heatsink.

DSC_1942

The heatsink is covered in yellow tape for isolation and a gray heat transfer pad.

DSC_1945

At the mains input is a fuse (F1) and two common mode coils (L1, ?) followed by a bridge rectifier (BD1). There are two mains switcher transistors on for 5V 2.4A and one for 2xQC (Q2). Between the two transformers are two safety capacitors and one opto-coupler for QC.
One the low volt side are two rectifier transistors (Q14 & Q15, synchronous rectification). The QC outputs shares a common mode coil and there is a inductor for each, they are mounted on two small circuit boards with the a QC controller each. There is also a small circuit board with 3 leds for the indicator on the front.

DSC_1943

With two transformers there must also be two switch mode controllers (U1 & U2). The opto-coupler for 5V is on this side (U3). For the 5V 2.4 outputs there is a synchronous rectifier controller (U4), a OpAmp (U7) together with a resistor (R69: 0.007ohm) to add the cable compensation to the reference (U8 and/or U10). Each of the 3 2.4A usb output has a auto coding chip (U11, U12, U13: probably CW3002).
The QC contains a 14.1V power supply that has a synchronous rectifier controller (U5) and a voltage reference (U9).
The actual QC controllers are on other circuit board that are soldered in slots with 6 connections on each side.

DSC_1950

DSC_1952 DSC_1956

The square chip (U15: marked AGQH569) is probably the buck converter.

DSC_1953 DSC_1955

The QC controller is here (U20: Marked PJK789)

DSC_1951

There is more than enough distance between mains and low volt side.

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



Conclusion

This is a good charger with lots of output current (I can fast charge 4 devices at a time), it has auto coding, low noise and two Quick Charge outputs.
