This clever design puts a cable extension and five power distribution sockets, neatly within the Systainer toolbox format. With 10m of cable contained in the box you no longer have to deal with loose cable and potential tangles. The box stacks and clips to your existing Systainers, SYS-Roll or SYS-Cart making transport and storage both neat and simple. There are four external sockets for power tools. A red light on the front indicates the SYS-PowerHub is ready for use when connected to the mains supply. The fifth socket is internal and protected against dust and contamination. The internal socket is useful for charging a phone or tablet, closing the SYS-PowerHub lid protects the item. The SYS-PowerHub has an integral thermal overload providing additional safety.
