Although wireless charging has existed for many years, it has been particularly popular this year. Wireless chargers have become the most popular accessories. It has brought a very convenient user experience to our lives. At present, more and more brands are involved in wireless charging.
After Hammer Technology's Bird's Nest conference in May this year, the official Mall of Hammer officially launched the wireless charger for Nut R1: Nut Alarm Clock Wireless Charging Stand. It supports 10W wireless fast charging. It is the first wireless charger listed on the hammer. At present, we have arrived at the editorial department of the rechargeable head net. Here we will bring it out of the box for dismantling.
One, nut alarm clock wireless charging station out of the box
White hard box packaging, simple design, printed on the product design. Nut R1 used with it, the phone screen will automatically show the time, turned page turning alarm clock.
Under the white background is a red product printing.
The bottom is marked with the product main information: product name (nut alarm clock type wireless charging stand), product parameters, manufacturer (Beijing Hammer Technology Co., Ltd.), and company contact information, address, product barcode, etc.
Open the package, there is a small box, tight packaging.
Open the box, inside the alarm clock type wireless charging base body and some attached items.
4. The lid of the box has holes and there are long strips on it.
Open a small grid, which is equipped with a charging line.
The contents of the entire package are: wireless charger, USB-A to USB-C charging cable, manual.
The part of the plug is textured and has a non-slip function. It can be seen to be well-designed and very hard.
The product is a terrace shape, the front is to put the phone, the material is silicone, non-slip, mobile phone is not easy to move, reduce the risk of mobile phone accidents. Inevitably there is a situation of caller vibration when charging, wireless charging stand silicone material design can effectively prevent The occurrence of accidents such as falling or falling mobile phones.
Common side for the PC material, feel tough.
The bottom is also silicone, which greatly increases the anti-skid ability. The charging base is not easy to move and it is stable.
Back of a USB-C input port and product related parameters.
Product parameters: Input: 5V/2A,9V/2A; Output: Max 10W. Model: WCD2000. Manufacturer: Beijing Hammer Digital Technology Co., Ltd. Made in China.
A bump below the front of the product is used to place the phone charging.
Place the iPhone 8 Plus above, almost the same size as the wireless charging plane.
It is not correct to place the mobile phone according to the instruction manual, and the back test stand cannot be charged.
The net weight of the product is 300g measured by an electronic scale.
Length 17cm.
Thickness 7cm.
Height 10cm.
Plug in next, ready to test the power of the product, insert the charging cable.
Tested by Chargerlab POWER-Z FL001super, standby current 24mA.
Power supply with music as QC3.0 head, can provide 7.8W output.
The new QC4+ charger that Nut has just released is also chargeable, Chargerlab POWER-Z FL001C test is 6.5W output.
Second, nut alarm clock type wireless charging seat dismantling
The bottom silicone sheet is torn off and there are four screws inside.
Remove the screws, and the charging head net has a non-slip adhesive on the screw.
Remove the panel, there are three coils, the three are diagonally distributed. Compared to a single coil, the three coils have the advantage of not picking up the charging position, that is, put the charge. In addition, the reason for this distribution is mainly It is to cope with the nuts R1 mobile phone: The nut R1 wireless charging receiver coil position is not completely centered, but is slightly to the right below (front view).
There are two screws that fix the internal structure.
Remove the screws and separate the charging part from the housing.
The PCB is on the bottom, separate from the coil.
From the back view, you can see that the entire back is affixed with aluminum heat sinks.
The bottom PCB is very clean.
Three coils, two temperature-controlled probes.
The PCB has 3 coil outputs and 13 NPO capacitors. This number can be described as unprecedented. When a product needs wireless charging, it will find the closest coil for wireless charging.
3 pairs of MOS tubes drive 3 coils respectively.
Output NPO capacitor and IDT drive signal switching chip.
Products using the United States IDT P9237 wireless charging program.
Winbond Winbond W25X40CL memory, 4Mbit, operating voltage range 2.3-3.6V, charge head network learned that this is used to store IDT P9237 configuration.
Winbond Winbond W25X40CL details.
USB-C input port.
PCB front view, almost all components are concentrated in the front of the PCB.
Third, the charge head net dismantling summary
Nut alarm clock wireless charger base design is simple and reasonable, Nut R1 with it turning body alarm function is also very interesting.
As for how the internal workmanship likes? The charge head net dismantling found that the internal workmanship is also very conscience: solid materials, configuration, luxury, cost expensive. USIDT P9237 wireless charging scheme, 10W fast wireless charging guarantee.
With three coils, the industry's rare use of 13 expensive NPO capacitors, as well as large-area aluminum heat dissipation, all of which provide a solid guarantee for the product's hardware performance.
