Test/review of Orico Dual Port Car Charger QPC-2U

Orico Dual Port Car Charger QPC-2U
DSC_5969
Official specifications:


  • Made of high quality durable aluminium alloy and plastic.
  • Dual USB, can charge two mobile devices at once.
  • Support to plug into any car power outlet.
  • The charger is very short and did not connect in my standard test socket.
  • With Blue LED indicator light.
  • Output: 2.1A & 1.0A.
  • Universal USB port works with most USB cables.

I got it from ebay dealer: orico_black_tech

The charger was in a box with specifications on the outside.

Measurements

  • USB output 2.1A is coded as Apple 1A    This is silly
  • USB output 1A is coded as USB charger (DCP)
  • USB outputs are in paralle.
  • Power consumption when idle is about 30mA on 12V and about 33mA on 24V
  • Weight: 15.5g
  • Length: 56mm
  • Diameter: 26.2mm

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: 39.4°C, HS1: 51.9°C
Temp6717
M1: 43.3°C, HS1: 52.7°C
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: 43.1°C, HS1: 58.4°C
It is about 6.5°C 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

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.
