Nowadays, living without a wallet or cash in major coastal or first-tier cities is becoming increasingly common. Whether it’s commuting to work, traveling, shopping, or even just strolling down the street, people are relying solely on their smartphones. But what happens if your phone runs out of battery? It becomes incredibly inconvenient. This is where wireless chargers come into play.
Let's evaluate the Electric Two W7100 wireless charger. This device consists of two main components: the wireless charging transmitter and the wireless charging receiver. The transmitter is powered by a 12V adapter, which then transfers power to the receiver via electromagnetic waves. Ultimately, the receiver channels energy into the smartphone, enabling seamless wireless charging.
The receiver of the Electric Two W7100 wireless charger we tested was specifically designed for the Samsung Galaxy Note 2. Known for its exceptional quality and performance in the mobile power sector, Electric Two has quickly adapted to the growing market demand for wireless charging. They introduced this genuine third-party wireless charging product at the right time to give users an authentic wireless charging experience.
Take a look at the receiver of the Electric Two W7100 wireless charger. It fits between the back of the Samsung Galaxy Note 2 and the battery. Given the limited internal space of the Note 2, the receiving end of the W7100 employs an ultra-thin design for better compatibility.
The receiver of the Electric Two W7100 wireless charger comprises two parts: the receiving coil and the adaptation circuit. The two metal contacts on the right side connect to the wireless charging interface on the side of the Note 2's internal battery. Installation is straightforward—simply place the wireless receiver so its metal contacts align with the internal charging module and secure the back cover to complete the setup. Keep in mind that since the receiving end lacks a fixed design, it’s best to install it while the phone is resting on a flat surface to prevent misalignment.
After installing the wireless charging module, you’ll notice a slight gap near the volume keys of the Samsung Galaxy Note 2. Despite the ultra-thin design of the Electric Two W7100 receiver, the Note 2’s compact back design leaves little room for error. However, users with phone cases will likely not encounter any significant issues during daily use.
Now, let’s examine the actual charging speed of the Samsung Galaxy Note 2 using the W7100 wireless charger. The testing method involved placing the phone on the wireless charging base when the battery was low and timing how long it took to reach full charge.
After approximately three hours of continuous wireless charging, the Electric Two W7100 wireless charger managed to charge the Samsung Galaxy Note 2 from 0% to 21%.
Features:
1. Designed for wireless charging.
2. Easy to install with simple operation.
3. Minimal heat generation during charging.
4. Base features a USB output interface.
Inadequacies:
The charging speed is relatively slow, and efficiency could be improved.
Moving on to wireless fast charging evaluations, more and more mobile phones now support wireless charging. Not only does this simplify the charging process, but it also reduces wear and tear on the USB data interface, thereby extending its lifespan. Wireless charging is undoubtedly the future of mobile phone charging trends.
The packaging of the Samsung vertical wireless fast charger is minimalistic. Its vertical design makes it easy to store the charging board. From the packaging itself, you can understand the product's functions.
The front of the charging base is sleek and simple, with Samsung's logo at the center and the word FASTCHARGE below it. There's also a charging indicator light that shows the charging status.
On the back, there’s only one Micro USB port used to supply power via a charging cable. The rear section of the charging base features a fan for cooling purposes. Upon closer inspection, you'll notice that the fan ports are not simply open but are slightly offset, showing attention to detail.
The bottom of the base is made of a non-slip material, providing basic protection for the charging board and phone. In the center, you’ll find specifications and manufacturing information.
For our tests, we used a Galaxy S6 edge+ with a 3000mAh battery and Samsung’s original charging head and cable. The actual measurement from 2% to 100% took 150 minutes. However, this test was conducted under normal usage conditions, leading to some power loss. Thus, the time required from 0% to 100% would be significantly less than 150 minutes.
The charging graph shows that the charging speed remains relatively consistent throughout. The efficiency of Samsung’s vertical wireless charging board is impressive, only about 40 minutes slower than wired charging. Considering the convenience of wireless charging, this efficiency is commendable. During normal charging, neither the phone nor the charging board generates excessive heat. The phone feels slightly warm, while the charging board remains cool, likely due to the built-in fan for effective heat dissipation.
Finally, let’s evaluate car wireless chargers. Wireless charging technology is gaining traction, and car wireless chargers are becoming more prevalent. Many cars already feature built-in wireless charging systems, such as Cadillac and Jeep. Some models allow for easy installation at a reasonable cost.
Raphon is a universal car wireless charging brand supporting devices like Nokia, Google Nexus 4, HTC 8X, and others that comply with the Qi standard. Raphon products include bracket accessories, charging cups, 5S mobile phone cases, cigarette lighter power cords, and user manuals. The suction cup has a multi-coil design, and the back features a detachable slider and vents. While the Velcro’s stickiness might weaken over time, cleaning and drying it usually restores its functionality. Raphon’s suction cup differs in that it contains coils, making direct rinsing impractical. Instead, it’s recommended to clean it with a damp cloth.
Additionally, this wireless charging device comes with a 5S mobile phone case. The Raphon case has a power connector, speaker openings, and an earphone jack, though the lower part might feel thicker. However, this doesn’t interfere with headphone insertion. Inside the case, there’s a coil structure to resonate with the device for efficient energy transfer.
The output power is 5V 600mA, compared to the original 5S device’s 5V 1A. Clearly, wireless charging is slower than wired charging.
The charging prompt occurs instantly upon placing the phone on the wireless charging pad. However, due to the unstable power output from the cigarette lighter, the charging time is longer, and efficiency is not optimal.
Despite these limitations, the convenience of eliminating frequent cable plugging and unplugging during charging cannot be overstated. The rise of wireless charging devices is imminent.
In conclusion, wireless charging is becoming increasingly popular across various devices, offering convenience and longevity benefits. Whether it’s personal electronics or in-car solutions, the future of wireless charging is bright.
