SunnyBag is an Austrian company that has revolutionized the way we think about portable power by combining solar technology with everyday bags. Their product line includes backpacks, shoulder bags, and other versatile designs, each tailored to different lifestyles. The commercial version is crafted from natural botanical calfskin leather, offering a sleek, minimalist messenger bag that exudes a subtle, earthy elegance. For those who want more personality, the personalized version comes in a variety of colors and materials, with shapes ranging from slim to wide—though some may find the style a bit too trendy for their taste. The light-inspired backpack, on the other hand, strikes a perfect balance between aesthetics and function, making it ideal for students or urban commuters.
Among all the options, the "LEAF" solar charger stands out as the most innovative. Designed to be lightweight, waterproof, and flexible, it resembles a leaf in both form and function. It can easily attach to any backpack, handbag, or even a tent using its swiveling hook system, making it compatible with over 99% of existing bags. Charging is simple—users can either use the PowerStick LEAF configuration or directly charge devices like phones, cameras, and tablets through the bag itself. While some users have successfully charged their LG phones, the iPhone 5C has yet to be fully supported, which might be a minor drawback for Apple fans.
In terms of performance, the LEAF delivers impressive results. On a sunny day, it charges in just 2–3 hours, while cloudy weather requires 5–10 hours, and rainy days take around 13–20 hours. Once fully charged, it can power a tablet up to 50%, charge a phone completely, power a camera twice, or illuminate a headlamp four times. This makes it a reliable companion for outdoor adventures, travel, or daily commutes.
The technology behind the LEAF is equally impressive. Solar panels integrated into the bag are designed to capture sunlight more efficiently than standard panels. The battery features three layers that absorb blue, green, and red wavelengths, achieving a 9% conversion rate under direct sunlight. With a power box that can be fully charged in as little as two hours, the LEAF is not only practical but also efficient year-round. In fact, it performs better in winter conditions than traditional solar batteries.
Currently, SunnyBag offers global shipping through its official website, making it easy for customers worldwide to experience the convenience of solar-powered mobility. Whether you're an adventurer, a student, or a busy professional, the LEAF is a smart, eco-friendly solution that keeps your devices powered without relying on traditional outlets.
Low Porosity Refractory Brick
Low porosity clay bricks are made of low aluminum mullite as the main raw material, formed by high pressure molding and high temperature sintering. The main mineral composition is mullite phase, the product has excellent high temperature physical properties and chemical erosion resistance.
Low porosity clay brick stability is good, the degree of erosion does not occur sudden change, than ordinary clay brick life increased by 2 to 3 times. Thermal conductivity, specific heat and solubility, respectively, than ordinary clay bricks 2 times higher than 10% and 40%, heat storage capacity than ordinary clay bricks 50% to 60% higher than the thermal efficiency of the kiln can be improved.
Low porosity clay bricks are characterized by:
1. Low porosity, 13 to 15%;
2. Load softening temperature is high for about 1472 ℃;
3. High compressive strength at room temperature, generally about 100MPa;
4. Good volume stability at high temperature and good abrasion resistance;
5. good resistance to infiltration and erosion.
Low porosity clay brick as a good clay refractory brick products, so often used in chemical erosion, temperature fluctuations in the environment, such as steel, glass, chemical industry. The effect is quite obvious in the use of glass hot room and the use of iron water tank.
