The Best Firman Generators -Buying Guide
Firman generators convert motive energy into electrical power for use in an external network circuit. A generator typically serves as an emergency backup system in the event of power failure. Keeping a generator handy is important because power outages can prevent you from completing numerous important tasks. For example, a power outage can prevent the output of heating or air conditioning, resulting in potentially serious health and safety concerns. Power outages can also cause food to spoil in the refrigerator at home or equipment and software to malfunction within businesses. Owning a reliable generator can help keep a power outage from turning into a much bigger disaster.
Keeping a spare generator can have practical benefits as well. You can use a generator to power your RV while camping or traveling. Generators make excellent resources for individuals in tropical climates prone to hurricanes or cold climates prone to blizzards. Most businesses can benefit from keeping generators on hand to avoid losing precious man hours due to damaged power lines or other environmental factors. In short, keeping spare generators handy can help keep your household or company running smoothly regardless of the emergency.
Firman generators are among the most reliable on the market. Since these generators come in a variety of models, it is understandable that you would have questions on how to choose the best generator for your needs. The following guide to Firman generators ensures that you can make an informed decision when selecting the best generator for your lifestyle.

Firman Generators - The Complete Buying Guide
The Firman generator is the flagship product of Firman Power Equipment. As a fully owned subsidiary of the multi-billion dollar machinery company Sinomach, Firman Power Equipment has produced more than 10 million generators over the course of nearly 20 years. North American equipment produced through the Firman brand undergoes over 500 hours of testing before production to meet American regulatory standards. Compliance organizations that regularly approve Firman generators include cETL (Certified Edison Technology Laboratories), CARB (California Air Resources Board), and EPA (Environmental Protection Agency seal). In addition, these products also undergo extreme-weather testing beneath blistering hot, heavily humid, or freezing cold conditions. This testing helps ensure great generator performance regardless of region or season.
One of the key benefits of the Firman production process is that it lowers the cost of buying a generator for the end customer. Consumer reports have shown that Firman Hybrid series, Performance series, and Whisper series tend to be more economical than generators from comparable brands. Moreover, the lowered production costs also translate into an increase in features from the manufacturing company. Specifically, the average tank size of a Firman generator is 25-percent higher than industry standard. This means that while other industry tanks are 3.4 gallons, Firman tanks are 5.0 gallons. And on larger generators, while other company tanks are 6.0 gallons, Firman tanks are 8.0 gallons. As a result, you can use a Firman generator for up to 12-14 hours before ever needing to refuel.
There are also operational benefits to using a Firman generator. Each generator operates via propane fuel or gasoline. This gives the user flexible options whether you are operating during natural disaster or driving during a long road trip. Many Firman generators also feature an extended propane hose that helps you use it with a large or dual propane tank.
The Firman Company's famous research and development (R&D) departments have resulted in design innovations as well. Patented design features like the Firman volt-lock automatic voltage regulator ensures clean and power generation, and the signature tubular roll-cage frame means that each generator is compact and built to last. Standard Firman generators include the u-shaped padded handle for ergonomic grip that makes it easy to push, pull, or lift the generator when needed. Firman generators that include wheel kits showcase trademarked never-flat wheels to ensure easy portability -- a great option for individuals who need to take their generators along on the road.
Firman Generators - Important Factors to Consider
When selecting your favorite Firman generator, one of the most important factors to consider is the right power output for your home or business. Try to get a reading on all of the appliances, electronics, or equipment that you plan to run with the generator. This reading will tell you the power requirements for your operation. As a general rule, the Firman generator should be able to give 20-percent more power than your average reading or power requirement.
The Firman generator operates on either liquid propane (LP) or gasoline. Although generators running on propane tend to run longer than those running on regular unleaded gasoline, the manufacturer does not favor one type of fuel over the other. In fact, many users prefer natural gas as it outpaces both LP and regular unleaded gasoline. The Firman Company also produces a Hybrid series of dual-fuel generators that provide the flexibility of using either gasoline or propane. With dual-fuel Hybrid machines, the choice is up to you and whichever type of fuel is available on hand.
Fuel capacity refers to the tank size. There is a direct relationship between fuel capacity and running time. In other words, the larger the fuel capacity or tank size, the longer your generator can run without needing to stop for a refill. Make sure you have a large enough fuel capacity (tank size) regardless of whether you plan to use liquid propane (LP) or regular unleaded gasoline.
The Firman Company recommends 10W – 30 standard oil. Individuals who prefer to use full synthetic should select 5W – 30 synthetic oil. Importantly, you should note that once you start using synthetic oil, the manufacturer recommends that you keep using synthetic to ensure the lifespan of product.
Your generator should also use the best start method for your environment and lifestyle. Each Firman generator can use any three different starters: remote wireless, electric, or recoil start method. Most Firman generators have electric and recoil start methods, and some Firman generators use all three starters. Although the recoil starter is the most traditional (employing a simple "pull-start" mechanism), many people prefer to use the electric starter instead. The wireless remote starter method adds another layer of convenience to an electric starter, so you may consider whether the model has a remote as well (especially if you plan to use the generator on an RV or road trip). Note that all Firman generators with electric start come with a lithium battery included.
You should consider if the outlet type matches the purpose for which you intend to use the generator. Firman generator can use any of four outlet types: standard outlet, DC plug, USB port, or RV-ready outlet. This type of built-in outlet determines the extent to which you can operate the generator.
Total Starting Watts
The generator you choose should also produce the correct total starting watts needed to power your devices. Watts are units of power used to quantify energy transfer. The simple formula for the Total Starting Watts for an individual appliance is as follows:
WATTS = VOLTS x AMPS
Volts are units of electromotive force, and amps are units of electric current. The required electric force and current tells you of how much energy you need to power everything from appliances to electronics.
What is the Difference Between Starting Watts and Running Watts?
It is important not to confuse running watts with the total starting watts needed.
Running Watts - The power needed to continuously run or operate an appliance or electronic device after it has already started. This is the continued stream of energy needed to keep a device on and running.
Starting Watts - The surge of power needed to start or boot an appliance or electronic device. Motor-driven appliances like refrigerators need this surge of energy to power up correctly. Note that total starting watts for large, motor-driven appliances may be twice the amount (wattage) of running watts. The total starting watts of your generator has to at least cover the highest starting watts of the largest appliance you want to use.
How Do I Determine the Total Starting Watts That My Generator Needs?
1. Decide which devices you plan to run simultaneously using your generator. Write down the Running Watts and the Starting Watts for EACH of these devices you want to use.
2. Add up all of the Running Watts for all devices you want to use at the same time. Record the total. This number represents the Total Running Watts.
3. From your list of devices, pick the device with the HIGHEST Starting Watts required. Record that number.
4. Finally, add the Total Running Watts to Highest Starting Watts. This final number represents the Total Starting Watts needed to power your devices in the event of an outage or blackout. As a rule, the generator you want should be able to produce at least the Total Starting Watts calculated for the devices you want to use.
