Nature's Generator 30A Automatic
#8 in 30 AFull review
An automatic switch for a power station or a generator, with lots of circuit space. Best paired with a battery that is always ready to take the load.

3.6/5
An outdoor six circuit switch that doubles as the inlet, so the generator plugs straight into it. Good for houses where the panel is on an outside wall or in a garage.

Nature's Generator 30A 12-Circuit
#9 in 30 AFull review
The most circuits for the money on a 30 A generator or 240 V power station. A good pick when you want to switch many small circuits.

A complete 30 A kit with an unusually long cord and easy rocker switching. Good for owners who want the generator parked well away from the house.
