Most generators with more than 3000w output are suitable to run all the appliances of a camper, however many campers also have an air conditioner. A 13,500btu air conditioner needs approx. 2800-3000w to start with a continuous running wattage of 1500-2000w. A 15,000 btu air conditioner needs approx. 3300-3500w to start, with a continuous running wattage of 2000-2500W. Check the power requirements of your air conditioner before making a choice of generator

The Cromtech Outback is the lightest (19.5kg) most compact model in its class. It has a max output of 2.4kw, it is portable, uses the inverter technology and has a continuous 2.1kw output.

The best generator for home use include; the no fuss and simple Cromtech petrol range of generators or the portable quiet Cromtech Outback and Cromtech Brumby.

kW is the amount of power capable of doing work, while kVA is the “vectorial summation” of KVAR and KW. kW is kilowatts, while kVA is kilo Volts Amperes. kVA is equal to kW in DC circuits because the voltage and current are in phase. In AC circuit at unity power factor KVA=KW.

A 2000 watt generator could power a 500 watt freezer and one element of an electric stove. Or you could run the freezer, cook with a 650 watt microwave (using 1000 watts) and a few lights. A 2000 watt generator won’t be able to power a hot water heater.

A 5kva generator at unity power factor (1.0), the maximum output is 5000 watts (volts x amps x power factor / 1000), but at 0.8 power factor (Some Crommelins generators) it will be 4000 watts. Continuous running power is usually 80% of that maximum output, so 4000w (0.8 power factor) has a continuous 3200w running.

Many devises need more power to start up (Maximum Output Watts) and then require less power (Rated Watts) to run continually. For example, a refrigerator requires 2200 starting wattage with a 700 running wattage, so you would need a generator with at least 2200 watt maximum output.

Homeowners can often power most household appliances using 3000 to 6500 watts. If your home has a smaller electric water heater you can generally expect 3000 to 5000 watts would be sufficient. If you have a large electric water heater, bore pump and/or large 8kg washing machine you will likely need a 5000 to 6500 generator.

Inverter Generators require a resistor type spark plug. As we have had reports of problems with other brands of plugs, we recommend keeping with the original NGK plug.

Altering the throttle position is not recommended as over-voltage or in some cases, under voltage, can damage these units. The cost of repair if this happens,  is usually around $200.
