The Andmon MINI400 is a capable solar-powered electric fence charger designed to energize up to 20 miles of fencing with its 0.3 joule output. This makes it suitable for medium to large properties. Its 18.5V/3W solar panel and 12V/4.5AH sealed lead acid battery provide impressive longevity, with the ability to run up to 14 days without sunlight, which is quite beneficial in less sunny climates. The device’s high reliability is evident as it operates in extreme temperatures ranging from -20 to 80°C.

Additionally, it boasts a durable IPX4 waterproof ASA outer casing, ensuring it withstands various weather conditions. The installation process is straightforward, and maintenance is minimal, making it user-friendly. However, the 0.3 joule energy output may not be sufficient for very high-intensity fencing needs or for containing extremely aggressive animals. Also, the product's weight of 2.7 kilograms may be a consideration for some users during installation.
