Description
The Firman W01785 is made with an 80 cc OHV 4-stroke engine that runs on gasoline. It has a 120V output and a running power of 1,700W and a peak power of 2,100W. Also, since the generator can work in parallel (but doesn’t come with a parallel kit), it can be linked to a second unit to make more power. The noise level of the inverter generator is 54 dBA, which is just a little louder than a conversation at home. It is started with a pull-start mechanism. Due to its 0.9 gallon fuel capacity, the W01785 can run for up to 9 hours on a full tank. It uses about 0.1 GPH of fuel per hour. The W01785 makes a clean sine wave. Its Total Harmonic Distortion (THD) is less than 3%, so you can safely plug sensitive electronics into its AC outlets.
Outlets
There are two AC outlets on the control panel: a 120V 20A (5-20R) receptacle and a 120V 30A (L5-30R) receptacle.
It also has 1 DC outlet and a 5V USB port (USB-A) that lets you charge devices like cell phones and tablets easily.Even though this Firman generator is not RV Ready, an L5-30P to TT-30R adapter can be used to connect it to an RV easily (included).Features
The lights tell you if there isn’t enough oil, if the generator is overloaded, or if it’s ready to use.
When it comes to safety, this product has an automatic low oil shut-off and an overload protection (circuit breaker), so you can use it without worry.The W01785 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.Along with the basic paperwork and an owner’s manual that will help you get the generator going right away, the Firman W01785 comes with a tool kit, funnel, oil, and an RV adapter.Mobility
The Firman W01785 is an inverter generator.
It has a case that is 20 inches long, 12.1 inches wide, and 16.7 inches high.So, it looks better than most other products with open frames.This kind of design is the most modern and easy way to make power for fun.The W01785 is called a lightweight portable generator, and it only weighs 45.9 pounds.The device is easy for one person to move, so its power can be used while on the go.The case is also made with a handle that makes it easy to carry and adds to its convenience.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.
