Loopz requires one 12VDC power supply for the pump, UV-C light, everything. There are many ways to hook up your electrical equipment and we have tried to accommodate most of them. The Loopz Filtration Module has a short cable with a heavy duty, waterproof and compact connector. To connect Loopz to a power source, you can select four additional “add-on” perks. We offer both a 5 meter and 10 meter extension cord. We also offer a 100-240VAC to 12V adapter (plug depending on your country) and a converter to a car lighter outlet.
