Hi, guys. Welcome back to today's video.
As a well-known distributor of accessories in Germany,
Hama focuses on adapters, cables, phone cases, and more.
Today, we got a 45W dual USB-C car charger from this company.
We gonna take it apart to see what components are inside.
It looks very simple, with a black plastic shell.
The Hama logo is on the front.
And all specs info are on the back.
Model is 00201632.
It supports DC input of 12-24V 6200mA.
The USB-C1 can support up to 25W output power.
And the maximum power of USB-C2 is 20W.
Except for PD, the USB-C1 can also support the PPS protocol.
It has passed CE certification.
Two cyan USB-C ports and an indicator light are on the output panel.
The maximum power is printed below two ports.
The weight of the car charger is about 32g (1.13 oz).
After connecting to the power supply, the indicator light turns blue.
At 14V DC input, the ChargerLAB POWER-Z KM003C shows
the USB-C1 supports FCP, AFC, QC3+/4+, PD3.0, PPS, and Apple 2.4A protocols.
And it also has two fixed PDOs of 5V3A, 9V2.77A, and two sets of PPS.
As for USB-C2, it supports FCP, SCP, AFC, QC3.0, SFCP, PD3.0, and Apple 2.4A protocols.
And it also has three fixed PDOs of 5V3A, 9V2.22A, 12V1.67A.
Switching to 24V DC input, the supported protocols and PDO info of USB-C1 are the same as those of 12V DC input.
And the USB-C2 is the same thing,
which means it can be used in different vehicles.
After the brief introduction, let's use the spudger to pry along the gap.
After removing the top case, we found
some silicone adhesives between two PCBs for heat dissipation.
Then, use the cutting machine to cut off the shell.
And take out the PCBA module.
It's composed of a long strip PCB and a small PCB.
Two USB-C connectors are on two PCBs.
The long strip thermal pad on the back can also enhance heat dissipation.
The plug-in components are on the front,
while the SMD components are soldered on the back.
This is the copper alloy spring on the positive side.
And the silicone wire inside can reduce the resistance.
A fuse is connected in series with the positive contact for overcurrent protection.
The solid capacitor for input filtering is from Shengtong Electronics.
100μF 35V.
This diode is connected to the input filter capacitor for reverse polarity protection.
And the synchronous buck IC is from Injoinic.
It integrates buck converter and the protocol chip,
which can simplify the PCB circuit.
This buck inductor can work with the buck IC we just mentioned.
The other buck converter is used for another buck circuit, from Chengxinwei.
It can support precise constant voltage and constant current.
And the input voltage can be up to 32V.
And this protocol chip is also used for another buck circuit, from Wing Semiconductor.
It can support multiple fast charging protocols.
The other buck inductor is for another buck circuit.
Those two solid capacitors for output filtering are 220μF 16V.
And two USB-C connectors are controlled by two independent buck circuits.
Well, that's all components for this 45W dual USB-C car charger from Hama.
It can support wide range input of 12-24V and can be used in different vehicles.
After taking it apart, we found it integrates two independent buck circuits.
It can ensure two phones are fast-charged at the same time.
But the 45W is not enough to charge your laptops or other high-power devices.
OK. That's all for today's video.
