Nowadays, smarter in coastal or first-tier cities is becoming more and more popular. Whether it is going to work, traveling, shopping, going to the streets without cards, without cash, just bring a mobile phone. If the mobile phone has no electricity, it will be very annoying. thing. With the evaluation of the electric small two W7100 model wireless charger, the electric small two W7100 is composed of two parts, which are wireless charging transmitter and wireless charging receiver. The charging transmitter is powered by the supplied 12V adapter, and then the power is transferred to the receiver via radio waves. Finally, the receiver transmits energy to the inside of the mobile phone, and a convenient wireless charging operation can be realized. The receiver inside the electric small W7100 wireless charger we designed this time is specially designed for the Samsung Galaxy Note 2 mobile phone. In the field of mobile power, the products of the electric small two have excellent quality and good performance. In order to adapt to the rapid development of the entire market, and to provide a good experience for those who want to experience wireless charging, electric Xiaoji introduced this true third-party wireless charging product in a timely manner. Let's take a look at the receiver of the electric small W7100 wireless charger, which is the receiver installed between the back of the Samsung Galaxy Note 2 phone and the battery. In order to better match the Note 2 with a small internal space, the receiving end of the electric small W7100 wireless charger uses an ultra-thin design to achieve better compatibility. The electric small two W7100 wireless charger receiving end is composed of two parts: the receiving coil and the adapting circuit. The two metal contacts on the right side are used to connect the wireless charging interface on the side of the internal battery of the Note 2 mobile phone. The installation method is as above. As shown in the figure, the installation is very convenient. After the wireless receiver is placed and its two metal contacts correspond to the wireless charging module contacts inside the Note 2 phone, the back cover is installed to complete the wireless receiver installation. It should be noted that since the receiving end of the electric small W7100 wireless charger does not have any fixed design on both sides, it is better to install the mobile phone on the desktop during the installation to avoid the metal contact offset. It can be seen that after the wireless charging accepting module is installed, a small gap appears in the volume key portion of the Samsung Galaxy Note 2, although the receiving module of the electric small W7100 uses an ultra-thin design, but the back space of the Note 2 mobile phone. The design is very compact, and there will still be some gaps after installation, but for those who have a mobile phone case, there is still no inconvenience in daily use. Finally, let us look at the actual charging speed of the mobile phone with the W7100 wireless charger. The specific test method is: when the mobile phone prompts that the battery is low, put on the wireless charging base to start wireless charging, and then calculate the value of the full charge at regular time. After about three hours of continuous charging using the wireless charging state, the electric small two W7100 wireless charger has a total of 21% of the charge for the Samsung Galaxy Note 2. Features: 1. Wireless charging mode design; 2. Simple operation, easy to install; 3. Low heat when charging; 4. Base with USB output interface. Insufficient product: The charging speed is slow and the efficiency is not high. Nowadays more and more mobile phones support the wireless charging function. Wireless charging not only facilitates the charging of the mobile phone, but also reduces the number of USB plugging and unplugging of the mobile phone. To a certain extent, it increases the life of the USB data interface, so wireless charging will inevitably become The trend of mobile phone charging development in the future. The following is a review of Samsung's vertical wireless fast charge. The packaging of the charging board is very simple. In order to conveniently accommodate the charging board, the outer packaging is also a bit of a "vertical" feeling, and the function of the charging board can be understood from the packaging. The front of the charging board is very simple and beautiful. The position on the center is Samsung's logo, and the lower position is FASTCHARGE. It indicates that the charging board supports the center of the front of the quick charging base. It is a charging indicator light that can indicate the charging status. There is only one micro USB port on the back of the charging pad base, which is used to supply power to the charging board through the charging cable connection plug. The rear seat of the charging board is a very fan cooling vent. If you look closely, you will find that the fan port is not simply open on the rear case. The two ports are separated by a certain degree. Processing is still very thoughtful. The bottom of the base is also a non-slip material, which is the most basic protection for the charging board and mobile phone. In the middle are some specifications and manufacturing information. The mobile phone used here is the Galaxy S6 edge+, equipped with a large battery of 3000 mAh, which supports fast charging; the charging head and charging cable used are the original standard of the Galaxy S6 edge+. Test data results: the phone is placed vertically when charging, the actual measurement from 2% to 100% takes 150 minutes, but the charging time test process is carried out according to normal usage habits, which will cause a certain amount of power loss, Therefore, the time required from 0% to 100% in the case of no operation should be much shorter than 150 minutes. Charging graph, through which we can see that the charging speed of the wireless charging board is relatively uniform at each stage. It can be seen that the charging efficiency of Samsung's vertical wireless charging board is still quite high, only about 40 minutes longer than wired charging. This efficiency is worthy of recognition under the premise of convenient charging experience and wireless connection! When charging normally, whether it is the heat of the mobile phone or the charging board is not serious, the mobile phone has only a little warm feeling, and the charging board feels like no heat, which may be due to the hanging behind the vertical charging board. Built-in fan, so the heat dissipation is very good. Wireless charging technology is becoming more and more widely used, and car wireless chargers have also opened up the market. At present, many vehicles have their own wireless technology charging boards, such as Cadillac and JEEP. Some of them can be installed by themselves, the price is cheap, and the installation is simple. The following is a review of the Raphon car wireless charger. Raphon is a universal car wireless charging technology brand that supports Nokia, Google Nexus 4 HTC 8X (International Edition) and other mobile phones that support Qi standard (the built-in wireless charging induction coil). Raphon products include bracket accessories, charging cups, 5S mobile phone distribution case, cigarette lighter power cord and instructions for use. The suction cup has a multi-coil design inside, and the back has a detachable slider design and vents. Whether the stickiness of the Velcro will be weakened with the long time of use, we have done the actual measurement in the early days. Generally, the Velcro, which works well after a period of use, can be returned to normal after being washed and dried with water. This is the case with Raphon, except that it has a coil inside it, so it is not convenient to rinse directly. It is recommended that the owner wipe it directly with a damp cloth. In addition, this wireless charging device is also equipped with a 5S mobile phone case. The Raphon phone case has a power connector, and the speaker exit and the position of the plug-in earphone are designed, although the lower part of the case will be a bit thick, but will not affect the insertion of the earphone. The inside of the mobile phone case has a coil structure for forming a resonance with the device to realize efficient transmission of electric energy. The output power is 5V 600mA, and the output of the original 5S device is 5V 1A. From this point of view, charging with a wireless charging device is slower than charging with a wire. The charging prompt is given immediately when the phone is placed on the wireless charging pad. However, in terms of charging time, because the power output of the cigarette lighter is not stable at all, the charging time of the vehicle wireless charging device will be long and the efficiency is not very high. What is certain is that with the advancement of wireless charging technology, the trouble of frequently plugging and unplugging cables is eliminated when the mobile phone is charged, and the popularity of wireless charging devices is just around the corner.
