Official specifications:
I got it from ebay dealer direct-england

I got this charger in a fairly plain cardboard box with a white wrapper.

DSC_2161

The box contained the charger, a usb cable and a instruction sheet.

The small hole above the green usb connectors has a blue led behind it.

Measurements


Load%20sweep%2011.6V
Load%20sweep%2014.6V

The usb outputs works fine at both high and low battery voltage and has a overload protection at about 2.6A

Load%20sweep%2011.6VQC5V
Load%20sweep%2014.6VQC5V

On QuickCharge the overload protection kick in at 2.3A

Load%20sweep%2012.0VQC9V

9V looks fine and has same overload protection.

Load%20sweep%2011.6VQC12V

With 11.6 volt supply the 12V QC output is a bit low.

Load%20sweep%2014.6VQC12V

But at 14.6V it is stable 12V.

No%20load%20voltage%20sweep

The charger needs a few mA for idle current.

Voltage%20sweep%202.4A%20input%20current

The normal usb output needs a bit above 1A at 12V to supply 2.4A on usb output.

Voltage%20sweep%202.4A

And the output will be stable down to below 7 volt input.

Voltage%20sweep%201.5AQC12V%20input%20current

QuickCharge will use 1.5A from 12 volt input to deliver about 12V output at 1.5A

Voltage%20sweep%201.5AQC12V

QuickCharge drops out of 12V mode at about 11 volt.

Load%20test%202.4A

There was no problem running 1 hour with full load (2.4A usb and 1.5A QC12V).

The temperature photos below are taken between 30 minutes and 60 minutes into the one hour test.

Temp2641

M1: 47,4C, M2: 44,2C, HS1: 64,4C

Temp2642

M1: 46,2C, M2: 44,9C, HS1: 61,4C

10ohm

The noise is very low with 10mV rms and 80mVpp

5ohm

A bit more load decreases the noise 8mV rms and 56mVpp

2ohm

Running all outputs at full load do not give much noise: 9mV rms and 88mVpp

qc5ohm

Mostly QC has fairly low noise, but not for all loads 5 volt 140mV rms and 441mVpp

qc9v5ohm

At 9 volt: 7mV rms and 94mVpp

qc12v10ohm

At 12 volt: 3mV rms and 68mVpp



Tear down

DSC_2440

It was fairly easy to open, I just removed the lid over the usb connectors, then everything was loose.

DSC_2441

With a QuickCharge and a normal usb port it needs two buck converters, this means two inductors.

DSC_2442

The green part at the 12V connections is a fuse (Very nice), then there is two switchers and two rectifier diodes.
U1 is EUP3466A and U3 is EUP3453, none of them has built in support for quick charge.

DSC_2443

DSC_2445

DSC_2447

The U4 chip is the auto coding chip for the normal usb port.

DSC_2446

There is a chip hidden behind the inductor, this must be the chip handling QuickCharge coding and controlling the switcher.


Being a 12V device there is no need to test with high voltages.



Conclusion

This is a very compact universal usb car charger and it will charge nearly anything at maximum speed.
If you need one or two charge ports in your car this is a good charger.
