The Firman P01202 is a 1200-watt portable gas generator built around an 80cc OHV 4-stroke engine with a cast iron sleeve. At this wattage, it powers small household appliances like microwaves, window air conditioners, and power tools, but not multiple heavy loads simultaneously. The 1.7-gallon fuel tank delivers 10 hours of runtime at 50% load, meaning a full day of intermittent use without refueling. Weighing only 55 pounds and measuring 17.5 by 14.2 by 15 inches, this unit fits in car trunks and garage corners. It runs at 64 decibels, which is moderate noise output suitable for residential areas when placed at a distance from living spaces.

Here's the quick tradeoff view — what this model does well, and where it may not fit.
The Firman P01202 is a gasoline-powered generator built for light-duty, grab-and-go scenarios where portability matters more than raw output. With 1,200 running watts and 1,500 starting watts, this unit sits firmly in the small-appliance tier. It can keep a few lights on, charge phones and laptops, run a small fan, or power a basic tool like a drill. It will not run a full kitchen or a window AC unit. For campers, tailgaters, and hobbyists who need a compact power source they can toss in a truck bed and forget about until it is needed, the P01202 fills that role well.
Firman has carved out a reputation for budget-friendly portable generators, and the P01202 reflects that approach. The 1.7-gallon fuel tank and 55-pound frame keep things simple and small. This is not a jobsite workhorse or a whole-home backup solution. It is a purpose-built portable unit for users who need a modest amount of electricity away from the grid.
The P01202 runs on gasoline and delivers 1,200 watts of continuous power with a 1,500-watt surge capacity for brief startup loads. That 300-watt gap between running and starting watts is narrow, so users should plan their loads carefully. A small power tool with a high inrush current could push the unit to its ceiling quickly.
At 50% load, the 1.7-gallon tank delivers up to 10 hours of runtime. That means running about 600 watts of equipment through an entire overnight stretch before needing to refuel. For a weekend camping trip where the generator powers a string of lights, a phone charger, and a small portable cooler, one fill-up could last from sundown to sunrise. The small tank size also means refueling is cheap and fast.
Noise output sits at 64 dBA, which is close to the volume of a normal conversation or a running dishwasher. At 20 to 25 feet away, it will be noticeable but not overwhelming. In a campground setting, placing it on the far side of a vehicle or behind a barrier will help keep the sound manageable for neighbors.
One important consideration is the 25% THD (Total Harmonic Distortion) rating. This is high. Sensitive electronics like laptops, smartphones, and medical devices can be damaged or behave erratically when exposed to unclean power. Users who plan to plug in anything with a microprocessor should invest in a separate surge protector or a power conditioner. This generator is better suited to resistive loads like lights, fans, and basic tools than to modern electronics.
The P01202 includes two 5-20R 120V outlets rated at 20 amps each. These are standard three-prong household receptacles, the same type found on most home walls. They accept everyday cords for lamps, chargers, fans, and small appliances without any adapters. Having two of them means users can run a couple of devices simultaneously without a power strip, though total draw across both outlets still cannot exceed the generator's 1,200-watt running limit.
A single 12V DC outlet rounds out the panel. This port works like a car cigarette lighter socket, making it useful for charging devices through a 12V car adapter or powering small DC accessories directly. It is a handy addition for camping setups where a 12V LED light strip or a portable tire inflator might come in handy.
At 55 pounds, the P01202 is light enough for one person to carry from a garage to a truck bed without help. That weight is comparable to a medium-sized bag of dog food. Picking it up, walking it to a campsite, and setting it down is a realistic one-person task.
The physical footprint of 17.5 by 14.2 by 15 inches is compact enough to fit on a closet shelf, slide under a workbench, or sit in the corner of an SUV cargo area without eating up much space. For apartment dwellers or anyone with limited garage storage, this small frame makes off-season storage a non-issue. The combination of low weight and tight dimensions makes the P01202 one of the easier generators to live with day to day, even when it is not running.
Starting the P01202 requires a recoil pull, the classic rope-pull method familiar to anyone who has used a lawnmower. There is no electric or remote start here, so users will need a firm tug to get the engine turning. For a unit this size, recoil is standard and reliable with minimal maintenance.
A built-in fuel gauge lets users monitor tank levels at a glance without opening the cap or guessing based on runtime. During extended use, this small detail saves real frustration. The outlet panel includes covered receptacles, which shield the plugs from rain, dust, and debris when the generator is stored or running outdoors. A spark arrestor is also included, which is critical for use in wooded or dry-grass environments where a stray spark could start a fire. Many national forests and public campgrounds require a spark arrestor for generator use, so this keeps the P01202 compliant out of the box.
The unit meets both CARB and EPA emissions standards, meaning it is legal to purchase and operate in all 50 states, including California, which enforces the strictest air quality regulations in the country. Firman backs the P01202 with a 3-year warranty, giving owners a solid window of coverage against manufacturing defects or premature failures.

These are estimates using typical wattage assumptions. Real appliances vary. Startup surges can be 2–6× the running wattage for motor-driven loads. 240V loads require a 120/240V generator and proper connection. Use a transfer switch or interlock kit; never backfeed a panel.
Firman is recognized for its durable and affordable generators that cater to both residential and small business needs, offering reliable power solutions.
