Description
The Firman T08072 has 120/240V power and can run on gasoline, propane, or natural gas thanks to its tri-fuel technology. It has a running wattage of 8,000W and a peak wattage of 10,000W when it is powered by gasoline. When it is powered by propane, it has a rated power of 7250 watts and a peak power of 9050 watts. It runs on natural gas and has a rated wattage of 5,500W and a starting wattage of 6,900W. The generator has a noise level of 74 dBA, which is just a little louder than a shower. It has a traditional pull-start mechanism as well as a convenient and easy-to-use electric starter (battery included). With a fuel capacity of 8 gallons, the T08072 can run for about 12 hours at 0.5 load on a full tank of gasoline (fuel consumption is approximately 0.67 GPH). If propane is used, it can run for about 5 hours (estimation based on a 20 lbs tank – propane consumption around 0.94 GPH). The T08072 can’t be used to power sensitive electronics because its THD is quite high (14%).
Outlets
The control panel has 5 AC outlets: a 120V 20A (5-20R) GFCI outlet, a 120V 30A (L5-30R) outlet, a 120/240V 30A (L14-30R) outlet, and a 120/240V 50A (14-50R) outlet.
Since it has a 14-50R outlet, this Firman unit is ready for an RV with a 50-amp service if you have an RV with 50-amp service.With an L5-30P to TT-30R adaptor, its L5-30R plug can also be used to connect a simple RV.The T08072 also has a twist-lock L14-30R receptacle, which makes it ready for a transfer switch.This means that it can power your home when the power goes out, as it can be easily connected to your breaker box.Features
On the T08072’s control panel, there is a handy meter that shows voltage, frequency, and lifetime hours so you can keep track of its status and activity.
Along with this information, a light lets you know right away if the generator is ready.The generator has a built-in fuel gauge that makes it quick, easy, and convenient to find out how much gas is in it.In terms of safety, the generator can be used without worry because it has a circuit breaker for overheating and an automatic shut-off when the oil level gets too low.The T08072 also has Firman’s CO Alert carbon monoxide shutdown, which turns the engine off automatically when harmful levels of carbon monoxide build up around the generator or when a CO Alert fault happens.It’s a nice extra safety measure, but don’t forget to take your generator outside at all times.The Firman T08072 comes with a funnel, a propane hose, a natural gas hose with an NPT adapter, a tool kit, and oil.It also comes with basic paperwork and an owner’s manual, which will help you start the generator right away.Mobility
With dimensions of L29.8 x W27.5 x H26.1 in, the Firman T08072 is a traditional, open-frame generator that is stable and can be raised above ground level.
This type of design is great for tough environments and heavy outdoor use.Even though this device is technically portable (meaning it can be moved), it weighs 213 pounds and can be hard to move and use without special tools.Still, because of its wheel kit (dia:10 “Once the generator is on the ground, it is easy to move thanks to its wheels and folding handle, which make up for its lack of maneuverability.Product Videos

- We compared more than 500 portable generators at 50% load. We found that there is “skewed right” distribution for the difference between 50% load and 25% load and the median comes at 1.43. With this number we converter all the 25% load runtime to 50% load. Same with the propane efficiency, where median is 1.38.
- For some generators where propane runtime was not given, we used NIST 1994 GGE (Gasoline Gallon Equivalent) formula: 5.66 lbs. of propane = 1 gal of gasoline. All propane runtime is for 20 lbs. propane tank (4.7 gallons).
- Unlike many other sites, we actually tried to find out information about each of the above requirements. However, we are human and are therefore capable of the odd oversight or mistake. Please let us know if you spot any missing or erroneous values so that we can fix them.
