1. A renal failure therapy system comprising:
a dialyzer;
a blood circuit in fluid communication with the dialyzer;
a dialysis fluid circuit in fluid communication with the dialyzer;
a housing supporting the dialyzer, the blood circuit and the dialysis fluid circuit;
a first electrical socket held by the housing, the first electrical socket including a first transformer and configured to provide a first voltage output for a first external electrical device; and
a second electrical socket held by the housing, the second electrical socket including a second transformer and configured to provide a second voltage output that is less than the first voltage output for a second external electrical device,
wherein the first and second electrical sockets are configured to power or charge the respective external electrical device via the respective transformer,
wherein each transformer of the first and second electrical sockets is configured to provide galvanic isolation to form an open cirucit and prevent propagation of fault currents, the respective transformer having an input coil separated physically from an output coil, the input coil magnetically inducing the respective first and second output voltages in the output coil, and
wherein each of the first and second electrical sockets includes electrical insulation for protecting a patient while powering or charging the respective external electrical device.
