Hello, everyone. Welcome back to our channel.
The old audiences know that we have torn down lots of wireless chargers and wired chargers
And today, we found a very special charger, which integrates wireless and wired chargers.
That's the 5 in 1 GaN wireless fast charger from fledging spruce.
We can see it consists of a powerful charger base and a wireless charging pad
And we can also transform it into a charging stand. Just like this.
The overall size is relatively big, so it should be placed on your desktop at home or office.
After folding the charging pad, it's like a square.
And this time we got the white version, it also has black and gray.
The shell still adopts flame-retardant PC. And the front charging pad is transparent acrylic.
Accidentally broken.
And the brand logo is in the middle.
The input port is on the back.
There are three USB-C ports and one USB-A port at the bottom.
The single USB-C can support up to 100W.
Single USB-A can support up to 36W.
The total power can reach 132W.
The wireless charging pad can support up to 10W.
There is an LED indicator here.
Another one is on the other side.
The specifications are printed here.
Product name is desktop charger.
Model is SPR140.
It supports input of 100-240V 50/60HZ 2.5A.
You can use it globally.
C1/C2/C3 can supports 100W max. USB-A can support 36W max.
For the rest of the information, I'll put it in here. You can pause to see it.
It has passed PSE, CE, FCC, ETL, RoHS, and other certifications.
As for the actual size. The length is 109mm (4.29 inches).
The width is 79mm (3.11 inches). The thickness is 47.2mm (1.86 inches).
Weight is about 474g (1.04 lb).
When power is on, the indicator light will turn blue.
Use ChargerLAB POWER-Z KT002 to test.
USB-C1 supports Apple 2.4A, Samsung 5V2A, DCP protocol
and QC2.0/3.0, AFC, FCP, SCP, PE2.0, PD3.0, PPS fast charging protocols.
It also supports five fixed PDOs of 9V3A, 12V3A, 15V3A, 20V5A.
And one PPS PDO of 3.3-11V 3A.
The protocol of C2 is the same as C1. As well as the PDO.
As for the C3 port. Exactly the same.
USB-A supports QC3.0, QC2.0, AFC, FCP, SCP, PE2.0 fast charge protocol
The bottom will form a groove after opening the charging pad.
Those holes on the back are used to dissipate heat.
You can choose your own way to charge your phone, no matter horizontal or vertical.
Then, let's take the compatibility of this charger.
When charging MacBook Pro 16-inch, the power is 89w.
When charging iPhone 12 Pro Max, the power is 23W.
When charging Mi 11, the power is 28W.
When charging Samsung S21, the power is 21W.
When charging OPPO Reno6 Pro, the power is 17W.
When charging OnePlus 9 Pro, the power is 17W.
When four ports are connected to the device at the same time,
The USB-C1 can still reach 83W. And the wireless charging part can work properly.
OK, that would be the brief introduction of this product,
then let's open it to see what's inside.
Remove the shell, and we can see the internal PCB is attached with a thermal pad.
Remove the black isolation board of bottom shell, we can see the metal heat sink.
And of course, another heat sink is covered on the PCB.
and it also exists on the top of the case to help dissipate heat.
There are inductors, capacitors, and transformer on the front PCB.
This charger adopts the architecture of PFC+LLC switching power supply.
The output has secondary step-down circuit.
The front side can be divided into four parts.
The input side is responsible for EMI filtering and rectification.
The middle is responsible for PFC boosting and filtering.
The left side is LLC circuit.
Those four small boards are secondary step-down circuits.
PFC boost and LLC control circuit are on the back.
This is the main controller, three GaN power transistors, and a silicon carbide diode.
Here is also a synchronous rectifier controller.
Here is a 5A time-delay fuse.
The surge suppressor resistor is next to it.
This is a varistor The yellow one is a safety capacitor.
Two common mode chokes are in here.
And the rectifier bridge is vertical to save space.
Here are two CBB capacitors and one inductor for filtering.
The middle one is the boost inductor.
Here are seven electrolytic capacitors in parallel,
used for filtering after boost.
The total capacity is 106μF.
The LLC circuit contains the transformer, LLC inductor, and LLC resonant capacitor.
The master control chip comes from NXP TEA2016AAT.
It integrates LLC controller, PFC controller, and multiple protection functions,
which can simplify the design and reduce components.
The PFC boost switch transistor is in here, which comes from Innoscience INN650D02.
Specification is 650V, 0.2Ω.
And the Maplesemi silicon carbide diode is next to it, packaged by DFN5*6.
It is suitable for high power density GaN chargers.
Those two are also Innoscience power transistors, which can form
LLC half bridge and are controlled by the master control chip to step down.
Here is the CT 1019 optocoupler, used to regulate voltage.
The synchronous rectifier controller comes from NXP TEA2095.
The corresponding position on the back is two synchronous rectifier MOSFETs.
Specifications of those two red filter capacitors are 25V 680μF.
We found the step-down circuits of three USB-C are identical.
A step-down chip and two step-down MOSFETs are on the front.
The step-down inductor and output filter capacitor are on the back.
This is a highly integrated dual-port ismartware protocol chip with multiple fast charging protocols.
Model is SW3518S.
It has passed VOOC certification and the maximum output power is 100W.
The two step-down MOSFETs and a VBUS switch MOSFET come from Maplesemi.
The specification of output filter capacitor on the back is 25V 220μF.
This single-chip microcomputer is used for intelligent power distribution.
There is also a step-down circuit on the small PCB of USB-A.
This is the high-efficiency synchronous buck converter.
It supports input of 7-38V and the output can be up to 6A.
Next, let's tear down the wireless charging pad.
This part consists of PCB and double coils.
This master control chip of wireless charging comes from injoinic IP6809,
which is also the world's first wireless charging chip
that supports QC3.0 input certification.
It supports 2-3 coils and output of 5-15W.
There are two drive MOSFETs of coil.
Those two are switching MOSFETs of coil.
All of them come from AGM-Semi.
Well, that's all components of this Fledging Spruce 5 in 1 GaN Wireless Fast Charger.
As a desktop charging station, this product can perfectly charge mobile phones, tablets,
TWS headphones, and laptops through four physical fast charging ports and a wireless charging pad.
It also has good protocol compatibility and output strategy of multi-port,
which can greatly improve the user experience.
But the disadvantage is obvious. Too big and a little bit expensive.
The current price is $89.99 on their official website.
