Nowadays, living in first-tier or coastal cities has become increasingly popular. People are embracing a lifestyle where everything from commuting to shopping can be done without carrying cash or cards—just a smartphone suffices. However, if your phone runs out of battery, it can be quite inconvenient.
Let's talk about the evaluation of the electric small two W7100 wireless charger. This model consists of two main components: the wireless charging transmitter and the wireless charging receiver. The transmitter is powered by a 12V adapter, and the energy is transmitted to the receiver via radio waves. Ultimately, the receiver transfers energy into the phone, enabling seamless wireless charging.
The receiver of the electric small W7100 wireless charger we’ve designed is specifically tailored for the Samsung Galaxy Note 2. In the realm of portable power solutions, the products from Electric Small Two are renowned for their superior quality and excellent performance. To keep pace with the rapidly evolving market and provide users with a top-notch wireless charging experience, Electric Xiaoji promptly introduced this third-party wireless charging product. Let’s examine the receiver of the electric small W7100 wireless charger. This receiver is installed between the back of the Samsung Galaxy Note 2 and the battery. To ensure better compatibility with the compact design of the Note 2, the receiver adopts an ultra-thin design.
The electric small two W7100 wireless charger receiver comprises two parts: the receiving coil and the adaptation circuit. The two metal contacts on the right side are designed to connect to the wireless charging interface on the internal battery of the Note 2. The installation process is straightforward. Once the wireless receiver is aligned with the charging module contacts inside the Note 2, the back cover is simply fitted to complete the installation. However, it’s important to note that since the electric small W7100 wireless charger receiver lacks a fixed design on either side, it’s best to place the phone on a flat surface during installation to prevent misalignment of the metal contacts.
After installation, a slight gap appears near the volume buttons on the Samsung Galaxy Note 2. Although the electric small W7100 uses an ultra-thin design, the backspace within the Note 2 is already quite compact. Despite this, users with phone cases should not encounter any significant inconveniences in their day-to-day use.
Finally, let’s evaluate the actual charging speed of the Samsung Galaxy Note 2 with the W7100 wireless charger. The test was conducted by placing the phone on the wireless charging base when the battery level was low, and we calculated the time required to fully charge the phone at regular intervals.
Using the wireless charging state, the electric small two W7100 wireless charger managed to charge the Samsung Galaxy Note 2 by 21% over approximately three hours.
Features:
1. Designed for wireless charging.
2. Easy to install and operate.
3. Low heat generation during charging.
4. Base includes a USB output interface.
Inadequacies:
1. Slow charging speed.
2. Lower efficiency compared to wired charging.
Nowadays, more and more mobile phones support wireless charging. Not only does this make charging easier, but it also reduces wear and tear on the USB port, thereby extending its lifespan. Thus, wireless charging is bound to become the future trend in mobile phone charging.
The packaging of the Samsung vertical wireless fast charger is simple yet elegant. The front features Samsung’s logo, and below it is the label “FASTCHARGE,†indicating that the charger supports fast charging. The center of the front is a charging indicator light that reflects the charging status.
On the back, there’s only one micro USB port for connecting the charging cable. The rear of the charger has a fan vent for cooling purposes. Upon closer inspection, you’ll notice that the fan vents are strategically placed to enhance airflow.
The base is made of a non-slip material, ensuring stability and safety during use. The bottom contains specifications and manufacturing details.
The phone used in the test was the Galaxy S6 edge+ with a 3000mAh battery and support for fast charging. Using the original charging head and cable, the phone went from 2% to 100% in 150 minutes. However, this test was conducted while using the phone normally, causing some power loss. Hence, charging from 0% to 100% would likely take less than 150 minutes without active use.
The charging graph shows that the speed remains fairly consistent throughout the process. The charging efficiency of Samsung’s vertical wireless charger is impressive, only slightly longer than wired charging. Its convenience and wireless connectivity make it a standout feature.
When charging, neither the phone nor the charger generates excessive heat. The phone feels slightly warm, while the charger remains cool, thanks to the built-in fan for effective heat dissipation.
Wireless charging technology is gaining traction in the automotive industry. Many cars now come equipped with their own wireless charging systems, such as those from Cadillac and Jeep. Some models even offer aftermarket options, making installation affordable and straightforward. Here’s an evaluation of the Raphon car wireless charger.
Raphon is a versatile brand offering car wireless charging solutions that support Nokia, Google Nexus 4, HTC 8X, and other devices compliant with the Qi standard. The product lineup includes bracket accessories, charging cups, a 5S phone case, a cigarette lighter power cord, and user instructions. The suction cup features a multi-coil design, and the back has a detachable slider with vents. Over time, the stickiness of the Velcro may diminish. However, our earlier tests showed that after cleaning and drying, the Velcro returns to its original condition. For Raphon, the presence of an internal coil makes direct rinsing impractical. Instead, wiping it with a damp cloth is recommended.
Additionally, the wireless charging device comes with a 5S phone case. The Raphon case includes a power connector, speaker outlets, and a headphone jack. While the lower part of the case is slightly thicker, it doesn’t interfere with headphone usage. Inside the case is a coil structure that resonates with the device to efficiently transfer electrical energy.
The output power is 5V 600mA, lower than the original 5S device’s 5V 1A output. This suggests that wireless charging is slower than wired charging.
The charging prompt is immediate upon placing the phone on the wireless charging pad. However, due to the instability of the cigarette lighter’s power output, the charging time is prolonged, and efficiency isn’t optimal.
Despite these limitations, wireless charging eliminates the hassle of constantly plugging and unplugging cables, making wireless chargers the next big thing in automotive tech.
