Hi, guys. Welcome back to today’s video.
We received many comments requesting the teardown video of the Baseus power bank from the blade series.
And here it comes.
It adopts an ultra-thin design and fits the size of the bag.
So, you can conveniently take it out.
Today, we gonna take it apart to check why it can be so thin.
Firstly, tear off the plastic film.
The pure black packaging is pretty simple and high-end.
It can support up to 100W output and 65W input, which is rare in ultra-thin power banks.
Open the box.
And take it out.
It contains a small bag and dual USB-C cable.
And also, the power bank.
The most important feature, 100W, is printed at the bottom.
And there’s an LED display at the top that shows the remaining battery, charging power, etc.
The twill texture surface can avoid the sticky feeling of the hand sweat
and make you hold it more firmly.
Some specs info are on the back.
Model is PPBLD100-S.
It adopts a polymer lithium battery, and the energy conversion rate exceeds 75%.
The rated capacity is 12000mAh.
It has passed CE and FCC certifications.
When charging multiple devices, the charging power is automatically adjusted.
But the total power is up to 100W.
You can pause to take a look.
There are four rubber pads at the corners to ensure stability.
The power button, two USB-C, and two USB-A ports are at the top.
And the specs info of every single port is next to them.
The size of the power bank is about 162 x 134 x 19mm (6.38 x 5.28 x 0.75 inches).
The power bank and cable are about 539g (1.19lb).
The USB-C connector is printed with the Baseus logo.
And the 100W means it can support up to 100W fast charging.
Our POWER-Z KM002C shows the same result.
The length is about 1.08m (3' 6.52'').
Then, let’s test the protocols.
The ChargerLAB POWER-Z KM002C shows the USB-A1 supports FCP, SCP, AFC, QC2.0, Apple 2.4A protocols.
And the other USB-A is the same.
And then, the USB-C1 supports SCP, AFC, QC3.0, PD3.0, PPS, QC5, and Apple 2.4A protocols.
And it also has five fixed PDOs of 5V5A, 9V5A, 12V5A, 15V5A, 20V5A, and a set of PPS.
The compatible protocol, fixed PDOs, and PPS of the USB-C2 are the same as that of the USB-C1.
As we mentioned, you can choose any USB-C port to charge and discharge.
The next step is definitely to take it apart.
As usual, use a spudger to pry along the gap and remove the back cover.
The inside of the back cover is reinforced by stiffener.
There’s a thermal pad on the back of the PCBA module for heat dissipation.
And the PCBA module is fixed with screws.
The battery pack is sealed and fixed with a blue heat-shrinkable cover.
Let’s separate the battery pack from the case.
And remove all the screws.
Take out the battery pack and the internal module.
The large screen, inductor, and some capacitors are on the front.
Then, disconnect the red and black wires connected to the PCB.
And then, we can use the knife to tear off the blue heat-shrinkable cover.
The battery pack consists of four polymer lithium batteries connected in series.
The battery protection board is under the barley paper for insulation.
The battery protection chip is from Joulwatt.
It supports 3-5 cells battery pack.
It also integrates a high-precision voltage detection circuit inside.
Those two battery protection MOSFETs are from Allepic Semi and are used to control the battery output.
Withstand voltage is 30V.
The sampling resistor can detect the battery pack’s current.
8mΩ.
The LED display module can be divided into three parts:
power percentage, output voltage, current, and remaining time, respectively.
Two toroidal core inductors are in the hollow of the PCB,
corresponding to six synchronous buck-boost MOSFETs and two buck-boost controllers.
The primary controller is on the back of the LED display module from Silan
and is compatible with various fast-charging protocols.
It can also analyze fast charging protocols of four USB ports and up to two USB-C ports.
An analog switch is from SG Micro, featuring low on-resistance, low voltage, and fast switching times.
And It’s a double-pole/double-throw analog switch.
The buck-boost controller of USB-C is from Southchip.
It is a synchronous buck-boost charging controller with I²C,
and supports battery discharge function.
The other buck-boost controller for another USB-C port is also from Southchip.
They are exactly the same.
Those three synchronous buck-boost MOSFETs are from Allepic Semi.
Same as the battery protection MOSFET.
The fourth MOSFET on the front can form an H-bridge circuit
with the other three for buck-boost conversion.
The toroidal core inductor is insulated with heat-shrinkable tube and fixed with glue.
Four solid capacitors on the front are all from BERYL,
corresponding to three-way output and the battery input.
100μF 25V for each one.
The VBUS MOSFET for USB-C port is marked with 7409.
Two buck ICs for two USB-A ports are from Ismartware
and are used for buck control and protocol identification.
Those two buck MOSFETs can work with two buck ICs, marked with 7446.
And those two MOSFETs are used to control the USB-A output.
Here is the power button, used for battery detection.
Two USB-C connectors are orange and sit between two USB-A ports.
While two USB-A connectors are also orange,
the internal contacts have been widened for high-current charging.
Well, that’s all components of this Baseus 100W ultra-thin power bank from the Blade series.
The flat design is completely different from other products in the market.
We cannot find an alternative option with the same powerful performance and the same flat design.
Those four USB ports can charge almost all your devices at once.
OK. That’s all for today’s video.

See you in the next video. Bye.
