Description
The Genmax GM1200i has a 57cc Dinking OHV 4-stroke engine that runs on gasoline, puts out 120V, and has a running power of 1,000W and a maximum power of 1,200W. Also, since it can work in parallel and comes with a parallel kit, its power can be doubled if it is connected to a second unit that works with it. The pull-start mechanism on the inverter generator is standard. It has a noise level of 58 dBA (lower decibel levels than rain). With its 0.7 gallon fuel tank, the GM1200i can run for up to 10 hours on a full tank (fuel consumption is approximately 0.07 GPH). The GM1200i makes a clean sine wave. With a Total Harmonic Distortion (THD) of less than 3%, you can safely plug your sensitive electronics into the AC outlets.
Outlets
On the control panel, there are two 120V 20A duplex outlets (5-20R). Also, it has 2 DC outlets: there are two 5V USB ports (USB-A) that make it easy to charge devices like cell phones and tablets.
Features
The lights tell you if the generator is ready to go, if the oil level is too low, or if it is overloaded. 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. It also has the CO DETECT technology from Genmax, which checks the amount of carbon monoxide in the air while the generator is running. If the generator isn’t set up right and carbon monoxide levels get too high, the generator will turn off by itself. It’s a nice extra safety measure, but don’t forget to take your generator outside at all times. The Genmax GM1200i comes with the usual paperwork and an owner’s manual , which lets you start it right away. It also comes with an RV adapter, a funnel, and a tool kit.
Mobility
The Genmax GM1200i is an inverter generator and has an encased design of the following dimensions: L16.5 x W9.5 x H15.7 in, So, it looks better than most other products with open frames. The goal of this modern design is to give recreational users the best way to get power. The GM1200i is a portable generator that weighs only 25.3 pounds. A single person should be able to move it around easily and get power wherever they go. The case is also made with a handle that makes it easy to carry and adds to its convenience. On our list of the 10 smallest portable generators, this one comes in at number 4.

- 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.
