These items will primarily run through their 110-volt circuits. The size of the generator you need depends on your power requirements. Typically, a higher power generator allows you to power more items at once. This generator sizing sheet will help you determine your running and starting watts so you can choose the right generator for your needs.
If your appliance has a plug, you can connect it to a portable generator, as long as the generator supplies enough electricity to power it. You can even connect many appliances at once, but collectively, they shouldn't consume more energy than the generator can supply. Doing so will cause the appliances to malfunction and could damage the generator. In addition, power cables can overheat and cause a fire.
Whatever the reason for the evening, generators are almost always needed for outdoor parties. DJ setup, dance floor lighting, food warmers, coffee makers, photo booth, and any heating or cooling unit need a power supply. Sometimes power can be consumed indoors, but you'll want to avoid overloading extension cords or trying to take them too far. Sometimes portable generators are sufficient for these uses, but large trailer-mounted units are often needed to provide enough energy for the environment.
To find out if you can run your welder with a 2000 watt portable generator, you need to know your welder's power requirements (refer to the data label or user's manual you received on your welder). Most importantly, they insulate your home and prevent the portable generator from feeding back utility lines, posing a serious danger to utility workers trying to restore power. Many schools and sports organizations rely on generators to power scoreboards, lights for night games, speakers for broadcasters, and other electronic devices. Extremes of heat and cold kill Americans every year, and the ability of a generator to power something as simple as a heater during a snowstorm could mean the difference between life and death.
When choosing a backup power source for your home, it's important to consider exactly what you need and want to be able to operate when the power goes out. In addition, because generators have engines that run on fuel and emit harmful fumes, they need proper ventilation; you should never operate one in an enclosed space. To turn on all the Christmas lights, grazing reindeer, or giant inflatable pumpkins, you may need to turn on the generator. Some appliances, such as refrigerators, air conditioners, and well pumps, consume additional power when started, and this increase in power can overload a generator.
We prefer to go for a very small emergency window AC unit, since 2000 watt generators can have very little starting power. You will find the power consumption of a device clearly marked on a label on its housing, usually near the point where the power cable is connected.
