Teardown of Baseus 20W Popsicle USB-C Power Bank (PPKDC05I)
Baseus launched two fast charging pocket power banks, which come with built-in cables. According to the different cables it comes with, it is divided into two types: USB-C and Lightning, which are used for charging Android phones and old iPhones. ChargerLAB has introduced this product of Baseus before, and you can click on the link to view it.
Next, let's take a look at the internal components and structure.
The Baseus logo and selling point description are printed on the front of the box.
The manufacturer info is printed on the back. I'll introduce the detailed introduction below based on the product itself.
The packaging contains a power bank, instruction manual, warranty card, and cartoon stickers.
It has a two-color gradient transition of blue and orange. The plastic casing looks like a thin layer of ice on the surface of a popsicle. The product is small and exquisite.
A major feature of the product is that it comes with a Lightning cable and is designed with a corresponding fixed slot on the body.
The cable can be used as a lanyard when not charging.
Four blue indicator lights, each representing 25% battery, making it easy to use.
In addition to the Lightning cable slot, there's a power button and a USB-C port on the top.
The plastic sheet of the USB-C port on the left is orange-red. The port area has a concave design, which can play a particular stabilizing role when plugging in the cable.
Specs infos are printed on the back.
Model is PPKDC05I. The battery capacity is 5200mAh. And the energy is about 19.24Wh. The USB-C can support up to 18W input power. And it can output up to 20W. The product has passed CE, FCC, and UKCA certifications.
The length of the power bank is about 93mm (3.66 inches).
The width is about 53mm (2.09 inches).
And the thickness is about 23mm (0.9 inches).
The lightning cable length is about 15cm (5.91 inches).
The weight is about 139g (4.9 oz).
The ChargerLAB POWER-Z MF001 shows that the Lightning cable is not original one.
The ChargerLAB POWER-Z KM003C shows that the USB-C port supports FCP, SCP, AFC, QC3+/4+, SFCP, PD3.0, PPS, and DCP protocols.
It has three fixed PODs of 5V2.4A, 9V2.22A, and 12V1.67A, and a set of PPS of 3.3-11V2A.
Now that we’ve finished unboxing this power bank, it’s time to take it apart and examine its internal components and structure.
The casing adopts a two-layer design; after removing the translucent casing, we can see the inner layer is a gradient color. It is very eye-catching.
After opening the case fixed by buckles, you can see that the light is covered with foam to avoid light leaks.
There is an aerogel sticker, which can reduce the surface temperature of the power bank.
The internal components of the power bank are fixed with screws. A white thermal pad is attached to the side of the PCBA module and fixed with foam.
After removing the top components, another thermal pad is attached to the PCB, and the battery is connected through solder joints.
There is a thermistor on the side of the two batteries, which is used to detect the temperature rise of the battery.
A thermal pad is pasted inside the casing.
There is also an aerogel sticker under the thermal pad.
Two batteries are connected in parallel. The battery voltage and limited charging voltage are 3.7V and 4.4V, respectively. The capacity is 2600mAh, and the power is 9.62Wh.
The battery protection chip, master control chip, 2.2μH alloy inductor, and Lightning cable are all on the front of the PCBA module.
And a power button, USB-C socket, and filter capacitor are on the back. The battery indicator light is covered by foam.
The SoC is from Injoinic and is used to provide a maximum output capacity of 22.5W and supports four port controls: USB-A x 2, MicroUSB, and USB-C. In application, only one inductor is needed to realize the buck and boost functions. Model is IP5356.
Here is all the information about the Injoinic IP5356.
The chip is from Xysemi and is used for overcharge, over-discharge, and over-current protection. Model is XB8886M.
