Builtin egg candling for easy inspection: A brightness LED candling light on the incubator control panel lets you check embryo development by turning the light on and off. This helps remove infertile eggs and underdeveloped weak sperm eggs. Even heating with rotating egg turning: The rotating egg turning provides more uniform heating during incubation, promoting consistent temperatures and greatly improving the hatching rate. Safe and versatile USB power: 5V ultralow voltage design for safety, making it reliable for use by the elderly and children. Power options include USB sources such as mobile phone chargers, power banks, computer USB ports, and car USB sockets. Use scenarios: Home backyard hatchery: Suitable for hatching chicken or other eggs with easy embryo monitoring and reliable, even heating. Educational setting: Ideal for classroom or family science projects to observe embryo development and learn about incubation. Portable or offgrid use: Incubation possible on the go or during power outages with a power bank or car USB charger.
