Hi, guys. Welcome back to today's video.
As the PD3.1 protocol is equipped on more devices,
more third-party chargers on the market can support 140W now.
And today, we got a 140W multi-port charger from Baseus,
equipped with two USB-C ports and a USB-A port.
Let's go ahead and take it apart to see how it works.
The front of the box is printed with Baseus logo and the product itself.
It is called the "GaN 5 Pro Fast Charger".
The specs info in different languages are printed on the back.
Tear off the sealing strip.
And take out all the items inside.
This is a 240W dual USB-C cable,
which can fully support PD3.1 protocol.
And the length is about 1.06m (3' 5.73'').
Connect the cable to the ChargerLAB POWER-Z KM002C.
It shows the cable is only used for 240W super fast charging.
Cause the data transmission speed is still USB 2.0.
The charger is pretty like the Apple 140W charger with a rectangular shape.
And the other side is printed with 140W GaN.
It continues the Baseus tradition.
A small indicator light is at the corner.
The specs info is pretty complicated.
Model is CCGAN140CS.
It can support input of 110-240V 50/60Hz 3.5A.
The manufacturer is Baolaipo Communication.
Only the USB-C1 can support 140W, and the other USB-C port can only support up to 100W.
And when charging multiple devices, the 140W output will be distributed automatically.
You can pause to take a look.
The input prongs can be folded, which is easy to carry around.
Take a closer look at the output panel.
All USB ports are orange.
And the C1 and C2 are printed below the USB ports.
The size of this charger is about 94 x 59 x 30mm (3.7 x 2.32 x 1.18 inches).
Compared with Apple 140W charger, the size is almost the same but with two more ports.
And the weight is about 287g (10.12 oz).
After connecting it to the power supply,
we can use the ChargerLAB POWER-Z KM002C to test the charging protocols.
The USB-C1 supports FCP, SCP, AFC, QC3.0/4+, PD3.1, and PPS protocols.
It also supports six fixed PDOs of 5V3A, 9V3A, 12V3A, 15V3A, 20V5A, 28V5A, and a set of PPS.
And the USB-C2 only supports PD3.0 instead of 3.1.
The rest of the protocols are same as C1.
And the PDO info shows it cannot support 28V 5A 140W.
Finally, the USB-A supports FCP, SCP, AFC, and QC3.0 protocols.
Next, let's use the spudger to pry along the gap and remove the bottom cover.
We can see a large area of pure copper heat sinks.
And cut off the white and black input wires.
We found the entire module is covered by the heat sinks.
And a layer of black Mylar sheet for insulation is under it.
Remove the top and bottom heat sinks.
And take off the Mylar sheet.
The gaps between different components are filled with gray silicone adhesives.
It can fix the components and dissipate heat.
Clean up the module.
All plug-in components are on the front,
including capacitor, transformer, inductor, etc.
And all SMD components are on the back.
ChargerLAB found it adopts LLC topology and has a PFC circuit.
The current will be filtered by synchronous rectification circuit for output.
The time-delay fuse is from Better Electronics.
3.15A 250V.
This is the blue varistor for overvoltage protection.
The first common mode choke is wound with magnet wires and insulated wires.
The safety X2 capacitor is from DGCX.
0.47μF.
The second common mode choke is wound with flat copper wires.
The model of the bridge rectifier is GBU1506.
15A 600V.
The film filter capacitor is 0.68μF 400V.
And the other one is 1μF 450V.
The filter inductor is insulated by heat shrinkable tubing.
The primary controller of the charger is soldered on a vertical PCB, from NXP.
It integrates the LLC controller and PFC controller to improve space utilization.
Those two tiny electrolytic capacitors from Yuguang Electronics can power the primary controller.
47μF 50V.
The GaN IC for PFC circuit is from Navitas and adopts QFN 6 x 8 package.
It integrates GaN FET, GaN driver, and logic circuit.
125mΩ, 650V.
This is the sampling resistor, used to detect the current of the PFC circuit.
It adopts 2512 package, and the resistance is 50mΩ.
The PFC boost inductor is tightly wound and insulated with yellow tape.
The PFC boost rectifier consists of three ultra-fast recovery diodes.
They are connected in parallel and marked with E5JB.
600V 5A.
Those three electrolytic capacitors for input filtering are from Yuguang Electronics.
27μF 450V.
The other electrolytic capacitor is also from Yuguang Electronics.
18μF 450V.
And 99μF in total.
Those two LLC MOSFETs are from HRmicro and adopt DFN8 x 8 package.
700V, 180mΩ.
The LLC resonant capacitor is 0.033μF 630V.
And the resonant inductor is wound with yellow tape.
The LLC transformer is also tightly wound with tape for insulation.
The SMD Y capacitor is from TRX.
Another blue Y capacitor is from DGCX.
This is the EL1019 optocoupler, used to regulate the output voltage.
The synchronous rectification controller is from NXP.
It integrates two independent drivers for synchronous rectification circuit.
Those two synchronous rectifiers are from Hunteck and adopt DFN5 x 6 package.
3.8mΩ, 65V.
Those three solid capacitors for output filtering are from Reloncap.
220μF 35V for each.
This is the inductor for output filtering.
The other three solid capacitors are 470μF 35V.
The synchronous buck-boost controller is from Southchip,
which integrates four switches and can improve output efficiency.
Those two MOSFETs are from Adamant and adopt PPAK 5x6 package.
40V, 4.3mΩ for each.
This is the buck-boost inductor, which is insulated with a heat-shrinkable tubing
and fixed with silicone adhesives.
Two protocol chips of USB-C2 and USB-A are from Ismartware,
which is used for step-down control and protocol identification.
And two buck MOSFETs are from ruichips.
The other two buck MOSFETs are the same.
Those two blue solid capacitors are from CapXon PT series,
used for output filtering of USB-C2 and USB-A, respectively.
470μF 25V for each.
Finally, the 8-bit MCU is from Chipsea and adopts MSOP10 package.
It integrates 12-bit ADC and is used to control the output power automatically.
Well, that's all components of this 140W PD3.1 charger from Baseus.
The USB-C1 can support up to 140W and has almost the same size as the Apple 140W.
But unlike the Apple 140W, it has an extra USB-C and USB-A port.
So, you can fast charge multiple devices at once.
After taking it apart, the internal layout is pretty compact.
Multiple small vertical PCBs can significantly reduce the charger's size.
It has two-way independent output circuits, used for USB-C1 and USB-C2, USB-A, respectively.
OK. That's all for today's video.
