Features To Consider With Portable Generators
The amount of power you need is one of the key features you need to consider prior to purchasing any portable generator. Think about the purpose for which you require a portable generator - is it a standby generator for instances of a power outage? Or, is it something to take with you when you go camping, or perhaps while tailgating?
If you are looking to run major household appliances, you will need a powerful portable generator that offers high wattage. Our FAQs below will look in a bit more detail about what size generator you should opt for to support your needs.
The next consideration when you think about power is the type of outlets a generator offers. For more simple applications, inverter generators tend to have AC outlets and sometimes USB ports, whereas larger standby generators feature 240V plugs and multiple AC outlets.
If you are purchasing a portable generator to serve as backup power in an outage, you will tend to find that they are quite bulky; this is due to their construction which helps keep them running for years to come. Large portable generators tend to feature an OHV engine and fuel tank, which make them heavy, especially when encased in a steel frame. On the other hand, inverter generators tend to be much smaller, although their range of applications are much more limited due to the lower levels of power they offer.
Noise level is a big consideration when it comes to purchasing a portable generator! Of course, any motor-powered appliance is going to come with some noise level, but the best portable generators use mufflers and other features to help reduce noise levels. To help you as you are deciding which generator is best, do bear in mind that the noise level of normal conversation is about 60 dB, so anything below this is excellent for a generator. If you have neighbors to consider, or your bedroom is located close to your garage where your generator operates, looking for a generator with low noise levels is key.
Many of the best portable generators include a range of safety features that help protect you and your appliances connected. One of the most important safety features to consider is overload protection; this will help ensure you do not connect too many appliances and devices to your generator, which could then become a fire hazard. Overload protection will recognize when the generator is being overloaded or if there are circuit issues and will automatically cease the supply of power.
Fuel Tank Size
There is nothing worse than waking up in the night during a power outage to realize your generator has run out of fuel and has turned itself off. If you do plan on running your generator for prolonged periods of time, looking for one with a large fuel tank will ensure that you get hours of use of a full tank. The smaller the fuel tank, the more often you will need to fill it.
Electric starts are the most simple kind of way to startup a generator and make it easy for nearly anyone to start it. Always ensure you keep your battery charged and ready for use. Pull start engines can take a bit of patience (and strength!), so they are not always suitable in emergency situations or for those that lack strength, perhaps due to a mobility issue or arthritis.
The ease of portability is a big consideration, especially if you wish to take your generator while out exploring. Larger portable generators are typically supplied on wheels and have a large handle that allows you to angle the generator back onto the wheels and take it to the location required; these kind of generators are good for job sites and home use.
Other compact generators, like inverter style generators, usually are much lighter and feature a carry handle on top of the unit, so you can easily bring it with you while camping, tailgating, or hosting an outdoor event. Some smaller generators are also supplied with a carry bag, which makes them even more convenient for travel.
Portable Generator FAQ
Q: What is a portable generator?
Portable generators are used to supply power to essential appliances, like your fridge, lights, computer, and even air conditioning units, in some cases. They are great as a backup source of power during power outages, but they do have a range of other uses. Some high power portable generators are capable of being paired with power tools, which makes them ideal on building sites. Smaller battery-operated generators can act more like a power station to help charge your devices and even power a CPAP machine.
Q: What can you run on a 2000 watt portable generator?
A 2000 watt portable generator is capable of running a range of small appliances, which why they are one of the best portable generators in power outages and similar situations. Here are some ideas of what can be run on a generator offering 2000 watts:
- Mid-sized fridge
- Portable AC
- Smart Air Purifier
- Lower powered microwave
- Smart bulbs
- Small mini split air conditioner
- Coffee maker
- Induction Cooker
Q: How big of a portable generator do I need?
The wattage level you require in a generator will depend on what you wish to power. Do note that there are two types of wattage levels you will typically see advertised - running watts and starting watts. Running watts advise the consistent level of wattage that can be supplied, whereas starting watts are only briefly available.
When thinking about what you need to power, you may initially have a long list, however, in a power outage, you will only want to think of the essentials. If you are on a building site, for example, you will need to consider the power tools used and whether lighting is needed. You can then add up the wattage of the essential or required appliances/devices required. Do remember that when motors kick in on certain appliances, they can draw more power for a brief period of time, so this is where looking at your starting watts is ideal to ensure your generator will not become overloaded and turn off during these moments of power surging.
If you are using your generator more recreationally, such as for camping, you will want to consider what light sources you will need, whether you will be using a portable air conditioner, and mini-fridge, for example, to help determine which sized portable generator will best cover your camping trips.
Q: How do you hook up a portable generator to your house?
If you are opting for a portable generator to cover you in times of power loss, learning how to connect it to your house is essential, reducing the need to run cables and extension cords all over the place. Start by determining your essential appliances and determine their wattage to ensure they can all run on your generator.
There are two wiring systems you can choose between when connecting your generator, either an interlock kit or a manual transfer switch. We highly recommend a transfer switch, while it is more expensive, it is much safer and is legal, whereas interlock kits are not approved everywhere.
You should hire an electrician to sort out all of the wirings to prevent any accidents, but an inlet box would need to be installed outside of your home and will have a recessed male connector that will be connected to the panel system inside your home. You can then plug your generator into this inlet box and plug the attachment cable into the generator.
Q: Can you run a portable generator overnight?
You are able to leave a portable generator running overnight, however, you need to ensure it is rated for long run times and is set up correctly so that it is shielded from harsh weather conditions. If you are running your portable generator in an enclosed space, like a garage, you will need to ensure there is proper ventilation; this is extremely important, as generators can emit carbon monoxide, and not having adequate ventilation can cause carbon monoxide poisoning. The best place to run your generator is away from your home, with the exhaust pointing away from any windows and doors. If you are running a generator in a well-ventilated garage, always install a carbon monoxide detector, which can help save your life as well as others living with you if levels get too high.
Q: How long do portable generators last?
Portable gas generators typically last anywhere between 2,000 to 3,000 hours, but this figure is entirely dependent on how often you use your portable generator and how well you maintain it. Portable power stations that are battery-powered tend to last for years, although it is important to note that you should always allow the battery to cool before recharging, as this helps extend the battery life.
Q: Are portable generators loud?
The majority of portable generators include a decibel rating which will allow you to compare noise levels. On the whole, most portable generators now run relatively quietly, with comparable levels to normal conversation or a dishwasher running in the next room. Inverter style generators typically run much more quietly than gas-powered. Don't expect whisper-quiet noise levels with any generator, but you can rest assured knowing you are still going to be able to get some sleep in a power outage with the majority of portable generators.
