But shopping for a generator can be a difficult and confusing task, especially in a market that is flooded with numerous options and varieties. Let's walkthrough the different types of generators available on the market, and help equip you with enough information to make an informed decision.

A generator is a device that can provide power to your house, office, or tools and equipment when you're on the go. Generators, contrary to what their name implies, do not generate electricity. Instead, they transform a different type of energy into electricity.

When there is an outage due to inclement weather, downed power lines, or other risks, generators can be utilized to provide backup power to your home or workspace. A generator is great for running a heating system, powering up the fridge, or keeping the shop running. When you're camping or traveling in an RV, you may also utilize them to provide power on the fly.



A gas-powered engine is used to power a portable generator, which is then turned on by an on-board alternator. Extension cords, electric-powered equipment, and appliances can all be plugged into the unit's power outlets. In most cases, the higher the wattage, the more items you can power up.

Pros: The main benefit of having a portable commercial generator is that it may be used in a variety of situations. Portable generators are designed to be easily transported because they are smaller than standard generators. Portable generators are less expensive than standby generators and don’t require significant effort to set up.

Cons: Portable generators can often create noisy sounds, and unlike standby generators, they do not automatically turn on when the power goes out. Some require starting by hand, though automatic start options are available. Some models (though not all) run exclusively on gas, requiring regular refilling.


To produce AC electricity, an inverter generator connects an engine to an alternator. Unlike other generators, it also converts AC electricity into DC power via a rectifier.

Pros: It is more environmentally friendly to choose an inverter generator over a normal generator, as these require less gasoline. Generators with inverters are genuinely portable. Because they're smaller and handy than normal generators, you can easily toss them into your car and take them with you wherever you go. Inverter generators are also very silent.

Cons: Amidst the advantages we get with an inverter, there are also drawbacks. Inverter generators are typically significantly more expensive, and also provide limited amounts of power. Depending on your needs, it may not be powerful enough to power home appliances or heavy-duty machinery and tools.


Standby generators, also known as whole-house generators, automatically supply power to your home. Within 20 to 30 seconds of detecting a brownout or blackout, the whole-house generator can start providing electricity automatically.

Pros: It works on its own. Provides long-term power protection. It will use the same sort of fuel that is already in use in the institution or at home. It detects a power outage and turns on the power, causing the outage to be felt only briefly. It can give enough power supply for the entire house.

Cons: Standby generators can be expensive, especially if they're big enough to power a whole house. Because they rely on a source of fuel, it's critical to ensure sure you have enough propane or that the generator is connected to your natural gas line. They require constant upkeep. 


Calculate what size generator you need in 3 simple steps

Step 1: Make a list of all the appliances you want to run.

Step 2: Calculate the starting and running wattages for each item on your list. You can use this wattage estimation guide as a reference (see below), if you can't locate these values on the appliance label.

Step 3: Add the wattage together. Then, use this number to guide what size generator you need.
