Solar PowerBank SBX-N32

Datasheet


Sometimes you just need to take something outside and disconnect it from all wires. You need an outdoor power source which can supply your system with enough power throughout the day and you need some sort of reliable connectivity to talk to the outside world or just supervise your system. This highly efficient and rugged outdoor power bank fulfills all requirements for industrial and reliable operation and supervision. It allows the user to operate devices in an outdoor setting without worrying about quality.
