Measurements
Load%20sweep%2011.6V%201A

The charger can deliver about 2.8A on the 1A output

Load%20sweep%2011.6V%202.1A

It can also deliver 2.8A on the 2.1A output

Load%20sweep%2011.6V

And the same 2.8A with using the outputs in parallel.

Load%20sweep%2014.6V

A bit higher input voltage do not change anything.

Load%20sweep%2024.0V

At 24V input the maximum current is down to about 2.2A, this is below the 12W rating.

Voltage%20sweep%202.5A%20input%20current
Voltage%20sweep%202.5A

The charger needs about 6V to maintain 5V output.

No%20load%20voltage%20sweep

When unloaded the current consumption is a bit above 30mA.

Load%20test%202.4A

I used the rated 12W, i.e. 2.4A for testing.
The temperature photos below are taken between 30 minutes and 60 minutes into the one hour test.

Temp6716

M1: 39.4C, HS1: 51.9C

Temp6717

M1: 43.3C, HS1: 52.7C

Load%20test%202.4A%2024V

I was a bit curious about 24V and also did a load test with 2.4A at 24V, it did not work as well, it could only maintain output for 5 minutes.

Temp6715

M1: 43.1C, HS1: 58.4C
It is about 6.5C hotter.

10ohm

Noise at 0.5A output is 34mV rms and 150mVpp

5ohm

Noise at 1A output is 35mV rms and 164mVpp

2ohm

Noise at 2.5A output is 53mV rms and 269mVpp, the output noise is low.





Tear down

DSC_6369

Some pressure on the sides and I could split it apart.

DSC_6370

The circuit is a single switcher IC (U1: LinTop LT6002C) with smoothing capacitors and a inductor.

There is nothing on this side.

The front circuit board contains the coding, for one connector it can be either DCP or Samsung, the other can be any Apple coding depending on resistors mounted.


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



Conclusion

This is a fairly simple charger with power enough to fast charge one device, but the coding do not correctly specify that.



Notes

The charger was supplied by a reader for review.
