The impression of Taobao has always been limited to platform service providers, providing an operating environment for the millions of stores in different locations. However, looking at Jingdong’s own business, Suning’s self-employed, NetEase’s selection of on-track earning has become a hot fire. Fire, Taobao also began to set up their own e-commerce 'Taobao heart', a variety of products, including two wireless chargers.
There are two models of Taobao Wireless Charger, black square and white round, they support the common devices supporting Qi wireless charging protocol on the market, and 9V fast charging mode can charge iPhone X up to 7.5W, which is the charging on the market. One of the most powerful products.
First look at the volume comparison, the left is the Taobao heart elect wireless charger, the right is a brand of wireless charger 500$, Taobao heart size slim like a little girl, is one of the smallest wireless charger on the market .
↑↑↑ input interface, Taobao heart selection of wireless charger uses a new type of USB-C input interface, support 5V2A (conventional) 9V1.67A (fast charge) two input voltages.

Four anti-slip mats are attached around the bottom of the one-piece aluminum sandblasting to avoid sliding when used. 
The following nameplate parameters are as follows: Product Name: Portable Wireless Charger, Model: TB-XX12 (Round), Input: 5Vdc / 9Vdc; 2A / 1.67A, Output: 5Vdc / 9Vdc; 1A / 1.1A, Execution Standard: GB 4943.1-2011, Manufacturer name: Hangzhou Xinxuan E-commerce Co., Ltd. 
Most of the wireless chargers on the market are made of plastic shells. The Taobao heart selection wireless charger shell material is relatively rare, the base is made of a single piece of aluminum CNC, better thermal performance than plastic products, panel selection Crystal-clear glass bonding, the overall appearance is to take a simple style line. POWER-Z FL001 monitoring standby, Taobao heart wireless charger standby hand QC2.0 fast charge, but running in the 5V gear , Standby power 0.049W is almost negligible. 
↑↑↑ After placing the iPhone 8 plus supporting 7.5W wireless charging, Taobao's heart rate wireless charger immediately jumps to the QC2.0 9V input, and the response speed is extremely fast. The maximum input power of the wireless charging board reaches 9.3V / 0.87A / 8.2W. 
Glass-lined panels work well, but the premise is that you don’t have a mobile phone case. After you wear the phone case, the glass panel will “stick” with the phone case. When you pick it up, it will remain stuck and cannot be removed instantly. .

Silicon is CS78S33 LDO regulator for the silicon, to provide stable power supply for the IC. 
瀚 is the CS4967 Wireless Charging Transmitter Control IC of Silicon Division. This is a wireless charging transmitter control chip that conforms to the Qi standard. The CS4967 integrates all control functions to minimize external components. CS4967 supports Qi standard multi-coils Application, integrated communication function compatible with WPC 1.2.4 standard, support two-way communication, support Qi wireless charging 15W power. It is worth noting that it also supports CBB capacitor over Qi 1.2.4. Support Foreign Object Detection (FOD) function, integrated high performance MCU, 8K Program Memory (Flash), 512B Data Memory. Integrated digital communication module for better compatibility.
Silicon Valley CS4268 + AON AO4616, coil drive. 
↑↑↑ 4 NPO capacitors, provide enough drive current. to sum up:
Say good not to engage in self-employment? (laugh). Taobao's heart-selected wireless charger's thin body is made of one-piece aluminum CNC shell, plus a crystal clear glass cover, is a rare material on the market with design.
Support Qi wireless charging protocol, can provide 7.5W wireless charging power for iPhone X. When measuring the iPhone 8 plus 74% charging, the wireless charging board input power reaches 8.2W. When the iPhone power is low, the charging power should be higher. .
After dismantling, it was discovered that Taobao chose a wireless charger to use a complete set of silicon wireless charging kits, CS4967 master + CS78S33LDO + CS4268 driver, with several expensive NPO capacitors, through one aluminum cooling The thin body can still support the 7.5W high-power charging mode. The work materials are all worth noting. At present, only the black Quartet is available on the Taobao Heart Selection Mall. The white disc style tested has not been found to be openly sold. Can pay attention to it.
