Using USB power supply, it eliminates the limitations of traditional plugs. As long as there is a USB port, such as on a computer, power bank, or car USB, you can easily power the heater. Whether creating a desktop aquarium in the office, taking care of small pet fish during travel, or keeping fish in the car, it offers flexible usage and provides suitable water temperature for the fish anytime and anywhere. 2. Maintaining a constant temperature of 26°C is ideal for most tropical ornamental fish. A stable water temperature environment effectively reduces stress reactions caused by temperature fluctuations, lowers the risk of illness, and allows the fish to grow healthy and lively, creating a vibrant mini-aquarium world for you. 3. The product dimensions are only 18mm in diameter and 85mm in length, making it compact and not occupying too much space in the aquarium. It perfectly fits desktop tanks of 25 liters or less, without affecting the overall aesthetics of the aquarium's scenery. It provides warmth for the fish while allowing you to fully enjoy the visual pleasure of the miniature aquatic landscape on your desk. 4. The power is only 10 watts, which is much more energy-efficient compared to traditional high-power heaters, making it more environmentally friendly. Long-term use will not significantly increase electricity bills, providing a comfortable living environment for fish while helping you save money, truly achieving both economy and practicality. 5. Equipped with safety explosion-proof features, made from high-quality explosion-proof materials, it effectively prevents electrical leakage and other safety hazards caused by accidental breakage of the heater, even in complex aquatic environments. This ensures safety for you and your fish, giving you peace of mind while using it.
