Introduction

Recently, we tested the USB-C inside the center console of the Tesla Model Y and Tesla Model 3. But if you need to charge multiple devices at the same time, two USB ports may not be enough for you. So, today, we're going to introduce and take apart a 45W expansion dock from Baseus for Tesla car.

Product Appearance

The packaging box got the biggest selling point printed on the front, which is 4-Port Expansion,

Flip to the back, here are the technical specifications in different languages.

Some specs are on the bottom. We will get to that later.

Open the box, these are some documents, like quick start guide, user manual, and stickers.

Then, take out the dock. It is made of ABS+PC flame-retardant material and features a black matte finish.

There's a retractable cable on the front. Two USB-A and a USB-C port are next to it.

Two USB-C input cables are on the other side.

The USB-C connector is vertical to the cable, which won't affect other things you put into the center console.

And the joint between the cables and the dock are protected by rubber sleeve.

Here are some specs info on the back. Model is BS-TS002. The input of USB-C1 and C2 are 9V 3A. As for the output, the retractable cable can be up to 45W. And the other USB-C port only reach 20W. But two USB-A ports only reach 12W. It also passed CE, FCC, UKCA certifications.

When you are not charging, the output panel can also be hidden to reduce dust and risk of damage.

It can be pulled out for passengers in rear seats to charge their phone.

Inside this groove, there is a magnet that automatically attaches when retracted, making it convenient and aesthetically pleasing.

The shallow stripes on flat cable can increase friction.

There's a Lightning adapter for you to convert the retractable cable into Lightning cable.

Both input cables are about 15cm (5.91 inches).

The length of this dock is about 104mm (4.09 inches).

The width is about 194mm (7.64 inches).

And the height is about 47.5mm (1.87 inches).

The length of the retractable cable is about 1M (3' 3.37'').

The total weight is about 313g (11.04 oz).

After powering on, the indicator light next to the USB-C port turns blue.

The ChargerLAB POWER-Z KM003C shows the retractable cable supports FCP, SFCP, SCP, AFC, QC3.0, PD3.0, DCP, Apple 2.4A protocols.

It supports five fixed PDOs of 5V/9V/12V/15V3A, 20V2.25A.

The other USB-C only supports PD3.0, DCP, Apple 2.4A protocols.

It supports three fixed PDOs of 5V3A, 9V2.22A, 12V1.67A.

As for the USB-A1, it only supports DCP, Samsung 5V2A and Apple 2.4A protocols.

So is the USB-A2.

Teardown

Now that we have completed our testing of this dock, it's time to take it apart and examine its internal components and structure.

Firstly, let's pry along the gap to remove the cover. Most space inside is quite empty, cause there's no switching power supply.

As we can see, there're three USB-C sockets inside the dock. And the last two sockets are connected to the two input cables below. The first one is used to connect main PCB to the module.

The retractable cable module is covered by an orange plate.

Continue the teardown.

The main PCB is fixed by screws.

And the dust-proof cover is fixed by magnets.

At this point, you might be a little confused. It clearly has two USB-A and one USB-C output port, so why are there three USB-C sockets on the PCB?

Looking at it the other way around, everything starts to make sense. In reality, it allocates the two USB-A ports on the output panel, one USB-C port, and one USB-C retractable cable, all to the two rightmost USB-C sockets at the back.

Besides, two synchronous buck-boost circuits for two USB-C and a buck circuit for two USB-A are on the front.

Those USB-C sockets and other chips are on the back.

Two USB PD Sink controllers are from Hynetek. Model is HUSB238. They can control the output of two USB-C ports. And the output power can be up to 100W.

Those metal contacts on the right small PCB are connected to the metal grooves on the left part. And the USB-C cable is connected to the USB-C connector on the main PCB.

Well, that's all components of this 45W expansion dock from Baseus for Tesla cars.

Summary of ChargerLAB

It brings two more USB-A ports to your Tesla car and exceeds the 27W charging limit. So you can fast charge more devices than before. And the retractable cable is very convenient for passengers in rear seat to charge their devices.

It can perfectly match your Tesla's center console. And the internal structure is relatively simple. Different output ports correspond to different buck-boost conversion circuits.

Introduction

The fact that the iPhone 15 series features USB-C ports is definitely good news in the long run. But it may not be so for long-time Apple users who have many Lightning cables. To prevent users from wasting resources, Apple has introduced the USB-C to Lightning Adapter.

ChargerLAB got this adapter immediately. And next, we will take a look at its build quality compared to similar products we have previously took apart, such as the USB-C to Apple Pencil Adapter.

Product Appearance

As usual, the packaging box adopts the Apple style.

It shows you how to use the product on the back.

The model is A2868.

This adapter is compatible with iPhone and iPad models that come with USB-C port.

The box contains the adapter itself and some documents.

The cable part is also in a woven design, just like the included USB-C cable for the iPhone 15 series.

The USB-C connector adopts a non-full-pin design, and the pins are gold-plated.

There is no protective sleeve between the connector and the cable.

And there's a Lightning icon on the other side.

The length is only about 11cm (4.33 inches), which makes perfect sense for an adapter.

And the diameter is about 3.6mm (0.14 inches).

This is how it looks like on my hand, pretty tiny.

The weight is about 10g (0.35 oz).

The ChargerLAB POWER-Z KM003C shows it doesn't have E-marker chip, obviously.

This product arrived before the iPhone 15 series, so we can only perform a simple test on the iPad Pro. The charging power can reach up to 25.75W.

Teardown

Next, let's begin the actual teardown.

Firstly, use the cutting machine to cut off the USB-C connector. Just the Apple 240W USB-C Charge Cable we just took apart before, it has a steel sleeve to protect internal components, which is fixed by plenty of solder joints.

Continuing to remove the steel sleeve, you can see a lot of potting compound on top of the black PCB.

All the wires are connected to this side, all of which are reinforced with glue.

And there are no components on the back.

Moving on to the Lightning part, it also has a steel sleeve to protect internal components.

There is soft rubber on the shell for fixing.

Continuing to remove the steel sleeve, there are two PCBs inside.

They were originally connected through the extension parts within the red frame.

The first PCB is covered with a lot of potting compound.

The solder joints of the wires are reinforced with glue.

The back only has potting compound.

The other PCB also has potting compound applied in the same way.

And there is nothing on the back.

Next is the cable, you can see red, yellow, blue and green wires.

There's a layer of white TPE, followed by the shielding net.

No aluminum foil.

Here is a close-up of the cable's internal structure, including the outer woven layer, white TPE, shielding net, and data wires.

These two positive power supply wires are made of tinned copper.

Here is the green wire.

Purple wire.

Yellow wire.

Blue wire.

These five bare tinned copper wires are used for negative power supply.

Well, that would be all the components of the two connectors and the cable.

Summary of ChargerLAB

In terms of build quality, the extensive use of potting compound inside and the special way of connecting the two PCBs are top-tier. And these advantages somehow justify the $29 price tag.

If you already have plenty of Lightning cables on hand, it is recommended to purchase this adapter to help protect the environment. If not, you may consider buying a brand new USB-C to USB-C cable instead.

Introduction

Those buying Nintendo Switch Docks should be very careful as fake docks that look just like the real thing have been spotted worldwide.

ChargerLAB has gotten a fake Nintendo Switch Dock, and let's take it apart.

Appearance

This fake Nintendo Switch Dock looks the same as the real one, which is hard to tell.

The dock has a black frosted shell with the NINTENDO SWITCH logo in the center of the front.

The left features an LED indicator as well as a display icon.

There are two black USB-A ports on the side.

There is a USB-C port to charge the Switch, and the whole dock can also serve as a stand.

There is a back cover, inside which is the cable organizer.

Inside the back cover is a square base on the right side.

The square base has one USB-A and one USB-C port on the side, as well as an HDMI output port.

These are the imprints of AC ADAPTER, USB, and HDMI OUT.

The bottom is equipped with non-slip pads. The parameters on the shell show it supports 15V2.6A input and 15V1.2A output and the NOM, NYCE, VCCI, EAC, and CE certifications. However, since it is a fake, the above parameters and certifications are questionable.

Its size is about 172.45 X 102.3 X 50.68 mm (6.78 X 4.02 X 1.99 inches).

The net weight is about 303g (10.68oz).

The ChargerLAB POWER-Z KT002 shows that the USB-A port supports Samsung 5V2A and DCP protocols.

The other USB-A port also supports Samsung 5V2A and DCP protocols.

Teardown

The fake dock adopts the same Y-shaped triangle screws as the original.

Take it apart.

These are air intakes for losing heat.

The PCB board is for power supply, HDMI output and USB transfer.

The flat cable socket connecting to the console is at the bottom of the small PCB board.

These are the very few components on the front of the PCB board and the screen printings of chip model, AG9311 for HDMI converter and FE1.1 hub controller for USB HUB.

A cable inside the shell connects to the USB-C port, and a wire is for the indicator.

This is the USB-C port.

The cover is supported by springs on the left and right side of the port.

The small PCB board is fixed to the spring bracket at the bottom by screws to act as a cushion.

Here is the spring bracket.

A USB-C connector is soldered on the front of the small PCB board, and the flat cable socket is below.

The USB-C receptacle is fixed and soldered by the vias.

These are the flat cable plugs.

The indicator is connected to the small PCB board with red and black wires.

This is the indicator on the small PCB board.

There are no components on the back.

This is the flat cable plug.

Two converter chips are soldered on the front of the small PCB board, and three buck chips at the bottom, outputting 5V, 3.3V and 1.2V, respectively.

The flat cable socket, capacitor, resistor and MOS tube are on the back. And the USB3.0 is led directly from the host controller.

Here is the flat cable socket connected to the USB-C port.

The ALGOLTEK AG9311 for DP to HDMI output supports DP1.2 input to HDMI1.4 output. It is a USB-C to HDMI solution, supporting 4K30Hz output.

The 27.000 MHz crystal is used to provide the clock signal for the AG9311.

The USB HUB is from CoreChips, Shenzhen, with the model SL2.2s. It is a USB2.0 HUB chip that supports four USB ports and BC1.2 mode. The 12.000MHz crystal is used to provide the clock signal.

The USB-C receptacle is fixed and soldered by the vias for input.

The USB-C input is transmitted to the synchronous buck circuit through a VBUS switch.

The VBUS switch is from AOS, with model AO4805. It is a dual PMOS with 30V withstand voltage and 10mΩ thermal resistance in an SO8 package.

Synchronous buck converter for 5V buck output has a screen printing of 3683 in the SOT23-6 package, with a 4.7μH inductor on the right.

The Synchronous buck converter, JW5250A from Joulwatt, for 3.3V buck output has screen printing of JWM3L, which has an input of 6V and output of 1A. It adopts the SOT23-6 package, below which is a 4.7μH inductor.

The 1.2V and 3.3V synchronous buck converters have the same model, both from Joulwatt.

This is the USB3.0 receptacle, fixed and soldered by the vias.

The HDMI receptacle is alos fixed and soldered by the vias.

The USB2.0 receptacles are the same as the previous two.

It is the outlet that connects to the indicator.

The MLCC filter capacitor for the USB 3.0 port is in the 1210 package.

That's all for the teardown.

Summary of ChargerLAB

This fake Nintendo Switch Dock looks just like the real one, and it's difficult to tell from the appearance. After taking it apart, ChargerLAB found that this dock uses only a DP to HDMI converter to convert the DP signal into HDMI signal output and a built-in HUB chip for USB2.0 expansion.

Compared to the original dock, the overcurrent protection chip of the USB-A port is omitted, while the buck circuit can not meet the needs of connecting high-power devices. Besides, many other chips are also not saved. So the security can not be guaranteed.
