Generator Types & Descriptions
Different portable generators will appeal to people depending on their needs. Each type has specific fuel requirements and features a unique build and structure.
When consumers know what they want, it makes buying a generator a lot easier.
Diesel-Powered
Most folks recognize diesel, but they may not realize that these generators are easy to maintain. They also last longer than gas-powered types. It is less flammable and better suited to heavy-duty machinery.
Since diesel is considered more of a premium fuel source, these types of portable generators often cost more. People should also consider the emissions, which are higher than many others and could cause harm to humans and animals.
Pros:
- Dependable strength
- Least flammable
- Longer shelf life than gasoline
- Suits heavy-duty devices
Cons:
- More expensive
- The number of emissions can be a problem
Gas-Powered
These portable generators are among the most common because of the convenience. It’s easy to fill up on gasoline since it’s widely available and inexpensive. Devices of this type come in different sizes and models, so there’s something for everyone.
While gas electronics are safe to use, they produce a lot of emissions. Therefore, this isn’t the best portable generator option for sustainability. Also, these units don’t hold up as well in colder climates or for long-term storage.
Pros:
- Most affordable
- Suits a range of power requirements
- Variety of makes and models
- Widely available
Cons:
- Not environmentally-friendly
- Storage can be an issue
Inverter Generators
Another less conventional option is a portable inverter. As the name suggests, it involves a built-in inverter that converts DC (direct current) in one swift motion. This makes it a good choice for smaller or more fragile devices.
Those who are looking for generators for home use should look into this option. One thing to remember is that these generators tend to be more complex, so upkeep isn’t the easiest.
This also hikes the price up. On the other hand, they’re very quiet and run more efficiently.
Pros:
- Fewer emissions
- Great for fragile or smaller devices
- Low noise levels
- More energy efficient
Cons:
- Can get quite pricey
- Complex engine interior (more difficult upkeep)
Propane-Powered
These portable generators offer a more environmentally-conscious option. They run on clean(er) energy and are also much quieter compared to others. While these devices help to cut down on emissions and fuel consumption, they are not without their dangers.
Propane is highly flammable, and setting them up can be a challenge. Storage can be tricky because it must be kept under high pressure.
On the plus side, its shelf life is good, and propane is affordable and available in most places. Just be sure to use it for smaller machinery.
Pros:
- Availability of dual-fuel generators
- Cleaner energy
- Save money in fuel consumption
- Usually a quieter option
Cons:
- Better for smaller devices

Portable Generator Buying Guide
The world of portable generators can be a bit confusing, especially for newcomers. So, here is a beginner’s guide to choosing the right appliance.
Once people know what it’s for and where to use it, they can better estimate their power requirements.
1. Determine the Required Power
First, consumers should think about where, when, and how they want to use their portable generator. That way, it’s easier to narrow down their energy requirements and start looking at specific models. For example, a property demands more output than something like a campsite. Also, consider the devices that will need power. Some examples include a microwave, refrigerator, or sound speaker. When it comes to wattage, keep in mind:
- Starting wattage is what's required for booting up the appliance.
- Running wattage is the recommended output to maintain a device continuously.
2. Consider Noise Levels
If people are going to bring a portable power source to an event or camping trip, they want it to be as quiet as possible. That may seem quite uncharacteristic for these types of devices. However, there are plenty of options that create far less noise. Something to look for while shopping around is a muffler or some kind of sound reduction mechanism. Most of these products hover around the 60-decibel mark. For reference, here's a guide:
- 30 dB: whispers.
- 50 dB: refrigerator buzz
- 70 dB: vacuum cleaner
3. How is it on Fuel?
Something else to consider, besides the type of fuel, is how much the device will use. No one wants to have to worry all the time about running out of gasoline or propane. Be sure to check the specifications and keep an eye out for things like fuel gauges, eco-throttles, and auto-adjustments.
4. Fuel Tank Run-Time
Along the same lines, consumers should consider the device's run time. Usually, the specs show this per quarter or half-load. For example, some portable generators can go for 8 hours at 50%. Keep that in mind when shopping around. If the purpose is for emergency backup, then it's better to go with longer run time.
5. User-Friendliness
Some people are well-versed in the world of portable power supply, and others are not. For the latter group, it's a good idea to check out some customer reviews. This way, it's easier to pick a product that's easy to use. Some features that can help include fuel gauges, a control panel or screen, electric start, and auto-shutoff.
6. Smooth Movement
Another thing that should come easily is the machine's overall operation. Remember, the larger the device, the more power it's capable of producing. That's great, but it might make it less portable. On the other hand, if the machine is small, then maintenance could be harder due to more components sitting in tight space.
7. Does it Have Enough Outlets?
Something that lots of people may overlook is supplemental outlets. This is important because it helps the appliance offset its load. While individuals don't want to occupy all of the outlets at one time, it helps to have more options.
8. Exhaust Output
Thinking about the different types of appliances, it's not hard to see that some emit more gases and fumes than others. As more people become aware of their environmental footprint, they might not feel comfortable with "dirtier" forms of fuels. For example, solar is a renewable energy source, and propane is better for the air than gasoline or diesel.
9. Price
Of course, individuals want to consider the costs involved in purchasing and maintaining these devices. Some figures to keep in mind include the initial price, the cost of fuel, and any service or maintenance. It's often better to spend more upfront for a trusted product of higher quality. Some factors that impact price include:
- Power level
- Noise rating
- Manufacturer reputation
- Fuel source
- Safety features
10. Service Support & Customer Reviews
Finally, it's always a good idea to check out some customer reviews before purchasing an item. This is especially true when looking at a big-ticket product like a generator. Take the time to look at client feedback and honest critiques. Also, don't forget about the warranty information. Some policies include the entire device while others only cover parts.
How Much Power Do You Need?
Yet another thing to take into account is overall power levels. As one might expect, different products have unique energy sources and stamina. Plus, consumers may purchase one of these devices for several reasons.
Below is a closer look at what kind of power ratings to look for depending on different circumstances.
Camping Power Requirements
As the weather gets warmer, more people are going to think about taking a relaxing camping trip. While campers want to pack lightly, lots of people have some non-negotiables that they like to keep on hand. For instance, people might bring along a coffee maker for their morning cup of joe.
Perhaps others want their laptop so they can work or watch movies in the evenings. Add all of these things up, and campers will need a device capable of generating 1,000 to 2,0000 watts. For reference, here are the wattage requirements for common camping supplies.
- Coffee maker: 600W
- Laptop: 200W
- Light: 75W
Home Power Requirements
Being at home is another story. The household is where family members have all of their prized possessions: phones, computers, kitchen appliances.
Some people may be more tech-dependent than others, so their power needs will be higher. It also depends on how many machines are running simultaneously.
Since most folks only need the generator for backup or emergencies, it’s probably going to use less power than on a typical day. Here are some points of reference:
- Electric heater: 4500W
- Microwave: 650W
- Small furnace: 3000W
Job Site Power Requirements
Those who have a job in the construction field may already be familiar with transportable generators. They need these devices to help power up things like jackhammers and drills.
On average, these workers need about 7500 watts to avoid power outages.
- Chainsaw: 1100W
- Circular saw: 1400W
- Hand drill: 600W
Recreational Power Requirements
There are plenty of times when folks need some extra energy to sustain their outdoor event, party, or concert. Whether they’re in their backyard or at a park, a compact inverter can keep the fun going.
