The Jebao WM series propeller water pumps have blown up in popularity in the last year or two, a trend driven primarily by extremely low cost. Being that this pump by Jebao is powered by a DC motor, it is quite simple and it makes sense that someone finally created a battery back-up for it.
The Aquarium Pump Extender is exactly that, a DC battery supply designed specifically for powering Jebao pumps when main electrical power is unavailable. Whether it is due to a power interruption, or a long road trip with large prized corals, the Aquarium Pump Extender can power any model of Jebao propeller pump for a long period of time without breaking the bank.
The Battery Back-up for Jebao pumps can be daisy chained either with multiple batteries for longer run time, or multiple pump for covering multiple tanks, and it offers a degree of peace of mind by automatically switching to battery power in the event of a power interruption. Priced at just $99, the Reef Breeders Aquarium Pump Extender can power a Jebao RW-4 pump for 48 hours, an RW-8 for 24 hours, an RW-15 for 18 hours, and the RW-20 for 12 hours. [Reef Breeders]
