Original OEM Fast Car Charger FB-001-QC2.0
I got it from ebay dealer: cnfu7527
- The car charger is Dual USB Interface.
- Input Voltage: DC 12-24V
- Output Voltage: Adaptive fast charging (5 V 2.5 A or 9 V 1.67 A)
- Compatible with: Fast charging with Samsung Galaxy S6, S6 edge, S6 Edge Plus, S7, S7 edge, Note 5, Note 4, Note Edge,Note 2. The other Galaxy will charger with output 2.0A.
No fancy box for this charge, just an envelope and a plastic bag, but it did include a USB cable.
The fake QC specifications.
- Fast charge USB port (#1) is coded as Apple 2.4A
- 2.1A USB port (#2) is coded as usb charger (DCP)
- Power consumption when idle is 21mA from 12V and 22.5mA from 24V
- The charger do NOT support any Quick Charge protocol.
- The two outputs are in parallel.
- The "Samsung" sign is lit.
- Weight: 20.7g
- Length: 72mm
- Front: 38 x 32.4mm
The QC marked output can deliver about 2.6A
And slightly less at 24V supply
The 2.1A marked output is exactly the same.
And also when they are used in parallel.
There was no problem running 1 hour with 2.1A load.
The temperature photos below are taken between 30 minutes and 60 minutes into the one hour test.
M1: 34.4°C, HS1: 57.4°C
M1: 39.3°C, HS1: 51.4°C
At 0.5A the noise is 61mV rms and 353mVpp.
At 1A the noise is 64mV rms and 406mVpp.
At 2.0A the noise is 74mV rms and 556mVpp.
I could easily pull the front off, but getting the circuit board out I broke a capacitor!
On this side is the two capacitors, the inductor and a led.
The "fuse" is a zero ohm resistor. The switcher (U1: HC8813) is a 2.1A chip with 10V to 30V input range and support for cable compensation.
Being a 12V device there is no need to test with high voltages.
This charger is a fake, it do not in any way support QC. With that said, it is an acceptable 2.1A charger, it is without any auto coding and has some noise.
