Hi, guys. Welcome back to ChargerLAB.
We have taken apart many Baseus chargers and desktop charging stations before.
And today, we got another unique product from the PowerCombo series,
which is slightly different from other products.
As we can see, it's more like a charging tower than a power strip.
And there's a retractable USB-C cable and two USB ports on the front.
All specs info are on the back.
Open the packaging.
And take out all items inside.
This charging station comes with a long power cord, which is not detachable.
And the rubber sleeve on the junction can enhance its durability.
The length of this power cord is about 1.5m (4' 11'').
The power button is at the top, which is convenient to control.
And after connecting to the power supply, the indicator light turns blue.
Take a closer look at the output panel.
It has a USB-C and a USB-A port.
The retractable USB-C cable can be pulled out.
And it'll be retracted automatically when you let go.
Except for the output panel, there are a total of three AC sockets on two sides and the back.
So, you can charge large appliances and small portable devices at the same time.
All specs info are printed here.
Model is CCGAN65-S3ACS.
The AC part can support up to 1625W,
and the DC part can support input of 100-125V, 50-60Hz 1.5A.
When charging a single device, the retractable USB-C cable can support up to 65W,
and the other two USB ports can only support up to 60W.
The size of this charger is about 113 x 66.5 x 66 mm (4.45 x 2.62 x 2.6 inches).
And the retractable USB-C cable is about 80 cm (2' 7.5'').
The weight of the charging station and the power cord is about 534g (18.84 oz).
The ChargerLAB POWER-Z KM002C shows
the retractable USB-C cable supports FCP, SCP, AFC, QC3.0/4+, PD3.0, PPS charging protocols.
And it also supports five fixed PDOs of 5V/9V/12V/15V3A, 20V3.25A, and a set of PPS.
The supported protocols and PDO info of the USB-C port are the same as the retractable USB-C cable.
As for the USB-A port, it can support FCP, SCP, AFC, QC3.0 charging protocols.
Next, let's go ahead and take it apart to see what it looks like inside.
Pry along the gap and remove the back cover.
The green, black, and white wires are connected to the internal module.
It can be divided into three parts.
The orange case is used to store the retractable USB-C cable.
The AC part is in the middle, and the DC output part is at the top.
Then, let's remove those fixing screws.
And now, we could take out the entire module.
ChargerLAB found it adopts QR flyback topology for fast charging.
Except for this switching power supply, there're another two switching power supplies,
used for relay control, power and touch detection.
And it's composed of four different PCBs,
which are control circuit, fast charging circuit, input detection circuit, and output protocol circuit, respectively.
Next, let's introduce all components inside one by one.
The input time-delay fuse is from Better Electronics.
3.15A 250V.
The green NTC thermistor is from Shiheng Electronics, used to suppress the inrush current.
The blue varistor is also used for input surge protection.
The safety X2 capacitor is from DGCX.
Capacity is 0.33μF.
The green common mode choke is next to the safety X2 capacitor.
The input bridge rectifier is soldered on a small vertical PCB, from World Industrial.
The electrolytic capacitor for input filtering is from Yongming.
27μF 400V.
The other two electrolytic capacitors are from CapXon.
33μF 400V for each.
The differential mode choke is between two capacitors.
The master control chip is actually a GaN IC from Southchip,
which adopts QFN6 x 8 package.
It integrates driver and can support multiple working modes.
The transformer is tightly wound and insulated with yellow tape.
The SMD Y capacitor is from TRX.
The optocoupler is used to regulate the output voltage.
Then, continue to talk about the synchronous rectification circuit.
The synchronous rectification controller is from Southchip.
And the synchronous rectifier is from Ruichips and adopts PDFN 5060 package.
100V, 8.5mΩ.
The solid capacitor for output filtering is from CapXon.
560μF 25V.
And the output current will be filtered by a toroidal core inductor.
There're two output circuits on this independent buck PCB.
So, there're two identical protocol chips from Southchip.
Withstand voltage is 40V, output current is 6A.
And a single chip can support the fast charging of a USB-C and a USB-A.
Those two synchronous buck MOSFETs are from Ruichips and adopt PDFN3333 package.
40V, 5.5mΩ.
Flip to the front.
Two USB-C and a USB-A connectors are between two capacitors and two inductors.
This USB-C connector is connected to the retractable USB-C cable.
The output VBUS MOSFETs are the same as the synchronous buck MOSFETs, from Ruichips.
Next, here is the top PCB with a touch sensor in the middle.
The buck IC is from Bright Power Semiconductor and adopts SOP7 package.
The sticker shows this transformer can support an output of 5V1A.
And the SMD Y capacitor is from TRX.
The Schottky diode is next to it.
This solid capacitor is also from CapXon PX series.
330μF 6.3V.
There's a layer of conductive fabric and foam over the touch button.
Four LED indicators are around the button.
This tiny chip is used to control the touch sensor.
An MCU is used for overvoltage and overcurrent protection.
And this is the optocoupler.
The groove under it can separate the primary and secondary sides.
Another small vertical PCB is used for input detection and control.
The input fuse is wrapped with heat-shrinkable tubing for overcurrent protection.
The bridge rectifier is on another side, used for input rectification.
1A 1000V.
Those two electrolytic capacitors are from CapXon.
2.2μF 400V.
The non-isolated buck converter is from Lii semiconductor.
It integrates a 750V MOSFET, and the output current can reach 150mA.
The buck inductor is insulated with heat-shrinkable tubing.
The detection chip from Hiliwi can measure the AC voltage and output current.
This 1mΩ current sense resistor can detect AC.
The white relay is from Hongfa, which is used to control the power supply of the AC module.
The contact current is 16A.
Finally, take a closer look at this orange case, which is fixed by a screw.
The retractable USB-C cable is stored in this orange case.
Those metal contacts on the right PCB are connected to the metal grooves on the left PCB.
Let's go ahead and remove it.
The internal USB-C cable is soldered on the back of this PCB.
And it's also directly connected to the USB-C connector on the internal PCB we just mentioned.
The retractable USB-C cable can be easily retracted when you let go.
Well, that's all components of this unique 65W charging station from Baseus.
The AC-DC 2-in-1 design is common these days,
but a retractable USB-C cable can keep your desk clutter-free.
After taking it apart, we found the internal structure is pretty compact.
And the internal module is stacked with four different PCBs, responsible for different functions.
The retractable USB-C cable is stored in a separate case.
And the connection method is pretty special.
OK. That's all for today's video.
