As the New Year approaches and the Spring Festival draws near, after a year of hard work, many of us are looking forward to taking some time off to relax and spend quality time with our families. One of the best ways to do that is by setting up a smart home theater. The Cool Music R4 Smart Projector, known for its "Reverse Twist Value," "Almighty Configuration," and "Super High Price," is an excellent choice for a family-friendly gift this season.
The R4 is a 1080p smart cinema projector from Cool Music Technology, a brand with 17 years of experience in projection technology. Despite its compact size—comparable to a small or medium biscuit box—it can project stunning full-HD images on screens as large as 100-200 inches. With a brightness of 880 ANSI lumens and excellent optical performance, it delivers cinematic-quality visuals in various environments. What makes it even more impressive is its price: at around 3,000 yuan, it offers incredible value compared to similar 1080p projectors that typically cost between 4,000 and 7,000 yuan.
The design of the R4 stands out from typical flat-style projectors. It features a vertical box-shaped body with a simple yet elegant look, available in classic silver or black. This not only gives it a sophisticated appearance but also makes it suitable for any home decor style. The all-metal construction adds durability and helps with heat dissipation, while the leather handle enhances portability, making it easy to move from room to room.
In terms of hardware, the R4 is packed with high-end features. It uses a Texas Instruments 1920×1080p HD display chip (supporting 4K), along with 880 ANSI lumens of brightness. It includes autofocus, dynamic focus, trapezoidal correction, gesture remote control, active shutter 3D, and wireless screen mirroring. With a short-throw ratio of 1.2, you can get a 100-inch image from just 2.65 meters away. The system is powered by a new 64MSTAR intelligent OS, Mali-T720 3D graphics engine, 3GB DDR4 RAM, and 16GB eMMC storage, ensuring smooth performance and high-quality image output day or night.
When it comes to audio, the R4 doesn’t fall short. It features a custom-built dual-channel sound system developed in collaboration with American audio brand AR. The system includes DBE dynamic bass boost, DSP sound field processing, and 360° Dolby surround sound. Even though the projector is small, the audio output is powerful and immersive, delivering a true movie-like experience.
For those who want even better sound, the R4 also includes an SPDIF digital coaxial output for lossless surround sound. And when you're done watching, the projector can double as a high-fidelity Bluetooth speaker, allowing you to connect your phone, tablet, or laptop and enjoy your favorite music anytime.
The user interface has also been significantly improved with the latest version of Cool OS. It now features a fresh, optimized layout and faster operation. Upcoming features like second-by-second boot and fastzone technology will further enhance the user experience. In terms of content, Cool Music has partnered with official licensees to provide a vast library of films, games, and office apps, ensuring users always have access to the latest and most complete entertainment options.
If you're looking to create a full-featured home theater this holiday season, the Cool Music R4 is an unbeatable choice. With its combination of high performance, sleek design, and affordability, it’s a perfect gift for the whole family.
100W PERC Mono Solar Cell
PERC mono panels are fabricated using monocrystalline silicon wafers, which are known for their high purity and uniform crystal structure. This results in a higher efficiency compared to polycrystalline or thin-film technologies. The "passivated" aspect of PERC refers to the treatment of the cell's surfaces with specialized materials that reduce recombination losses, allowing electrons to flow more freely through the cell. This is achieved by applying an oxide layer on both the emitter and rear surface, improving the cell's light absorption and reducing the reflection of light.Unlike traditional cells where the front side is used for the emitter, PERC cells have the emitter on the rear and the contacts on the rear as well. This design minimizes shading effects caused by the front contacts, leading to improved efficiency under low-light conditions.
Key Features
1. Higher Durability: The multi-busbar design can decrease the risk of the cell micro-cracks and fingers broken.
2. High Power Density: High conversion efficiency and greater power output are achieved through lower series resistance and improved lighting.
3. PID Resistant: Tested in accordance to the standard IEC 62804, our PV modules have demonstrated resistance against PID (Potential Induced Degradation), which translates to security for your investment.
4. Bigger Cells with better performance: A slight increase of the size of our cells, Boosts the performance of the newest modules by six percent on average.
In summary, sunpower monocrystalline solar panels are a testament to the ongoing innovation in solar technology, offering a balance of high efficiency, durability, and cost-effectiveness that makes them a preferred choice for both commercial and residential solar energy projects worldwide.
