Are you looking for a portable generator to power up your home during an emergency? The 12000 watt portable generators are the best on the market. This article will give you all of the information that you need to know about these generators so that you can make an informed decision. We’ll look at some of the most popular models and review them with pros and cons, as well as helpful tips about how to use them correctly.

What Can a 12000 Watt Portable Generator Power?

The short answer is that a 12 000 watt generator can power just about everything in your home. That said, it will depend on the size of the appliance and how much electricity they consume. Let’s take a look at some examples to see what appliances are ideal for this type of generator:

  • Refrigerator
  • Air Conditioner
  • Sump Pump
  • Furnace Fan (in emergencies)
  • Hot Water Heater

Other appliances may be able to run with reduced capacity or not at all which means you’ll want to prioritize powering them up first during an outage. This would include things like lighting, television/computer systems, fans, etc. Depending on where you live there could also be restrictions regarding running larger appliances depending on the time of day. If you’re unsure, we recommend calling your local utility company so that they can inform you of the best way to help them during an outage and where possible to avoid drawing too much power from their grid system.

How to Choose the Best 12000 watt portable generator

Who should buy 12000 watt portable generator?

This generator is ideal for those who have larger homes or just need a lot of power more than 10000w generator can provide. For example, if you’re constantly running multiple appliances at the same time then it would be beneficial to get an electrician out and upgrade your electrical system so that you can take advantage of more electricity without blowing fuses in your home. If not, however, these generators are great because they don’t require any additional work on your part other than filling them up with gas when necessary (generators do vary though so make sure to read product specifications before purchasing).

You’ll also want to consider whether you should buy one big 12000 watt generator or several smaller ones depending on how many things powering during an outage. That said, you should keep in mind that these generators are often very loud – quieter than they used to be but still quite loud. If noise is an issue then it might not be the best idea for your home, especially if there’s a possibility of sleeping while using one.

  • Transfer Switch

It offers the utmost safety when using a generator as your backup plan. It also bolsters your powering ability and protects your generator from damage. You can choose between a manual and automated transfer switch, although the automatic one is slightly expensive.

  • Upkeep Needs

It is important to take good care of your generator, especially if you want it to last for a longer time. For example, change the oil and air filter every 50 hours. Be sure that the gas tank is full at all times after each use because this will allow easy starting in case there’s an emergency.

  • Local Laws

Make sure that you are aware of the local laws regarding emergency generators. For example, some areas have restrictions on where to place your generator in case there’s an outage. It is best if their installation area can be clearly seen by all so as not to obstruct views or pose any safety hazards at night for vehicles and pedestrians alike.

  • Power usage

Knowing how much power you are going to need for your generator will allow you to pick the one that matches your needs. The best choice would be an inverter because it can regulate its wattage usage depending on what appliances or devices are in use at a given time.

  • Noise levels

Although it is a good idea to use generators in an emergency, you should not run them for too long at a given time. They produce very loud noise that can be harmful and disruptive. Noise levels of up to 60 decibels are common among most generators; however, they can go as high as 90 decibels or higher if the engine size increases.

  • The running time and fuel capacity

The larger the engine of a portable 12000 watt generator, the longer it will last on just one tank or load. If you plan to use several appliances at once, then look for one that has higher fuel capacities. On average, generators with up to 5000 watts can run continuously for about eight hours while those with more than 8000 watts can go on for around six hours before needing refueling.

  • Portability and assembly

The more portable a generator is, the better. You should look for one that can be easily moved and placed on different locations such as your garage or deck. The weight will also factor into this decision because some units are very heavy and difficult to move around especially if you don’t have the proper equipment with you.

  • Ease-of-use

Since you will be using your generator for emergencies, it is best to choose one that can easily be started up. Many generators today come with electric starters so they don’t require pull-cords or other complicated starting mechanisms. Other models have an automatic turn on feature which allows them to power up as soon as the engine starts running and shuts off when it stops completely.

  • Price

Last but not least, you need to balance between the price and quality of a generator before making your purchase. Don’t just look at one or two factors because these can be misleading; instead take into consideration all important aspects such as power usage, noise levels, durability, ease-of-use etc.

Key Features of a 12000 watt portable generator

Lightweight and Portable

Most of these generators are under 100 lbs which makes it easy to transport between your home, garage or shed if necessary.

Electric Start Option

Many manufacturers offer electric start options so that you don’t have to start their generator manually with a pull cord (although this is still an option for some models). We recommend checking to see what the model you’re looking at offers before purchasing since each one varies in terms of size/type.

Quiet Mode Function

This function allows users to reduce noise levels up to 50% while using quieter mufflers as well as high frequency inverters for even more power output. In our opinion, however, unless you live far from other homes then it’s not likely going to be worth the extra cost.

Fuel Efficiency

It’s important to consider how long you can run your generator before it needs gas, especially if there are multiple people in your home who will need to use it at different times throughout the day or week. This is often measured in hours which means that 12000 watt generators typically have a longer life than smaller models when running appliances with lower power output.

Parallel Capability

This feature allows generators to be connected together so that they can share the workload. In other words, if you have two of these 12000 watt portable generators then it will double your power output which is ideal for larger homes with multiple appliances requiring electricity simultaneously.

Digital Gauge/Monitoring Panel

Most models come equipped with a digital gauge or monitoring panel so that users are able to see how much gas and oil they have as well as engine temperature levels during operation.

Tips for using the 12000 watt portable generator

  • If you live in an area where it’s often windy, make sure to secure the generator with ropes or chains; choose a model that comes equipped with wheels for easier transportation.
  • If your electricity went out during summer months when temperature is high, don’t leave the generator outside – this will cause overheating which might damage engine parts making them unusable until repaired (requires professional assistance).
  • Don’t forget to check oil level on regular basis and refill if needed using only suggested type of motor oil as instructed by manufacturer. Otherwise, unit can become damaged over time due to lack of lubrication preventing proper functioning.
  • Keep the generator away from water and other liquid spills while working in damp conditions. If caught in rain, make sure to turn it off immediately; also avoid any contact with floodwater (risk of electric shock).
  • Make sure that children or pets stay at least 15 feet away from the unit when powering up as there’s always a possibility for machine parts becoming loose which can cause injuries if stepped over by someone unaware of such risks.
  • Don’t leave your 12000 watt portable generator outside during winter months – low temperatures might affect performance significantly making engine work harder than usual until heated enough thus draining too much power, leaving nothing left for later use.
