Dual power supply with automatic switching: The incubator can be connected to a 12 V battery and a 110 V power supply at the same time. In case of a power outage, it automatically switches to the 12 V battery power. Automatic egg turning and sizeadaptive roller spacing: It can automatically turn eggs and adjust for eggs of various sizes. The incubator turns eggs every 90 minutes, and the distance between the rollers automatically adjusts according to egg size. Fully automatic hatching mode: A completely automatic hatching mode can be selected. The incubator can incubate chickens, ducks, pigeons, geese and other eggs. After configuring the temperature in the machine, it controls all eggs. External water function: To increase the water volume, simply add water from outside the incubator. The incubator has small holes and is waterproof. If the amount of water is too large, it will overflow. Use scenarios: Small farm or hobby hatchery requiring uninterrupted operation in areas with unstable power supply, thanks to dual power and automatic switching. Breeders who hatch multiple species (chickens, ducks, pigeons, geese) with automatic turning and size adjustments to fit different eggs. Remote locations or temporary setups where mains power is unavailable and battery backup ensures continuous incubation.
