Anker brought two wireless wireless chargers for the PowerWave 7.5 series on the MWC 2018, the horizontal PowerWave 7.5 Pad and the vertical PowerWave 7.5 Stand. Unlike the common 5W wireless chargers, they not only support the Apple 7.5. W also supports Samsung 10W wireless fast charge. Previously, the charge head net dismantling the horizontal one, today brings you a vertical PowerWave 7.5 Stand unpacking.
I. ANKER PowerWave 7.5 Stand Unpacking
The ANKER PowerWave 7.5 Stand is packaged in blue on a white background, maintaining the brand's consistent design style. The following line of small print indicates that this is a packaged version with an adapter: PowerWave 7.5 Stand with Quick Charge 3.0 Charger.
Backside product promotion information, along with some simple authentication information.
Observing the package carefully, we can see that the surface pattern is pressed up, and the simplicity adds rich details at the same time, which instantly raises the product to a higher level.
Open the package and you can see the inside is ANKER PowerWave 7.5 Stand vertical wireless charger body, a data cable and an adapter.
The data cable is a Micro USB connector with a magic cable tie and the adapter is Anker PowerPort+1 QC3.0 charger.
The adapter has only one USB interface, supports QC3.0 fast charging and Anker smart IQ charging, and can intelligently identify the device to distribute the appropriate power.
With foldable pins for easy carrying.
Next is the ANKER PowerWave 7.5 Stand vertical wireless charger body, with a white body and an ANKER logo on the front.
The charging panel and the base have an angle of about 60°. When the mobile phone is used for daily charging, it is convenient to see the notification message and other contents at a glance without having to pick it up.
Looking from the back, the cross section of the pedestal is in the shape of a track, with a certain thickness, and it seems that the key components are hidden inside.
The bottom of the product is an anti-slip rubber pad with the main parameters of the product printed on it. Product Name: PowerWave 7.5 Stand; Model: A2522; Output: 10W (MAX) Input: 12V 1.5A.
The small circle in front of the pedestal is the aperture work light, which is usually in the extinguished state. When it is working, it will light a light blue aperture, and moderate brightness will not cause light pollution.
Wireless charging has an excessively high temperature and limits the charging power. Therefore, as a wireless fast charging product, heat dissipation is a problem that must be solved. There is an elongated air inlet at the top of the back of the charging panel. Because it is hidden behind, don't worry about getting into the ash.
The back of the pedestal is a Micro USB type input interface, and a large area of ​​grid-like ventilation and cooling holes is located next to the pedestal. It matches with the top air inlet to discharge the internal heat of the product in good time.
Second, ANKER PowerWave 7.5 Stand dismantling
Remove the cover and double-sided adhesive assists the fixation between the front of the coil and the housing.
Two-color indicator light is soldered on the small board.
Two wireless charging coils, each with a corresponding thermistor probe, are used to detect the temperature rise during charging.
Coil solder joints have a fixed glue, increasing strength.
There is a centrifugal fan on the back of the board.
AVC's centrifugal cooling fan, 5V 0.3A, speeds up the heat generated during the wireless fast charging process.
Since this wireless charger is a vertical design, there are 2 charging coils, so there are 3 half-bridge drivers and different drivers are combined according to different coils.
WP80025 is a wireless charging control chip launched by Yichong Wireless. The charging head network has found that it supports Qi-BPP 5W, Apple 7.5W fast charge, and Samsung 10W fast charge. 12V input, 10W efficiency 67-75%, charging height 3-8mm, CE/FCC/Qi-EPP certified, integrated over-temperature protection, over-current protection, over-voltage protection, and foreign object detection.
TI's LM324 4 op amp.
Input common-mode inductance to suppress interference conduction.
STI3472 switch buck. 600KHz fixed frequency, input voltage range 3.5-18V, maximum output current 2A.
MPS MP2229 synchronous rectification buck, voltage conversion inside the wireless charger.
Charging head net found that 8 NPO capacitors are lined up in a row, and this number is rare.
Half-bridge drive close-up, a FD2105M drive two AON7544 as a half-bridge.
Family portrait, this is the end of dismantling.
Charge head net dismantling summaryANKER PowerWave 7.5 Stand vertical wireless charger adopts active cooling design. The built-in centrifugal fan takes away the heat generated by the coil and circuit board to avoid the problem of limited charging power caused by excessive temperature. The use of MPS, TI, AO, Yi Chong wireless and other major brands of materials, as well as 8 expensive NPO capacitors, materials, luxury work, provide a reliable guarantee for the performance of the product.
