Our FIRMAN verdict
FIRMAN is the answer to the question Predator raises. Similar value positioning, but three years of warranty instead of ninety days, and tri-fuel on most of the range so a natural gas line can feed it during a long outage. Check whether the unit you are looking at is new or refurbished, because that swaps the warranty from three years to three months.
Dual-fuel 4550/3650W $899.99 up to tri-fuel 16800/13500W $4,699.99, read from firmanpowerequipment.com in August 2026. Refurbished units are sold alongside new ones and carry 90 days instead of three years, so check which you are buying.

Strengths & considerations
What it does well
- +3-year warranty on new units, matching Champion and Honda rather than the budget tier.
- +Tri-fuel across most of the range, so a natural gas line removes refuelling during multi-day outages.
- +Wide price ladder from $899.99 to $4,699.99 without leaving the brand.
Where it falls short
Sourced, not our opinion. This is the part the brand's own page leaves off.
Refurbished carries 90 days against three years for new. The listings look similar and the warranty difference is the whole value proposition.

Support runs through the manufacturer rather than a dense dealer network, so a repair is a shipping and scheduling exercise.

The open-frame models are storm-duty loud. The Whisper and inverter series cost more.

Before you buy: confirm these
These are FIRMAN's own documented terms and open questions, not our test results. Get the specifics in writing on the quote before you order.
- ?Confirm new versus refurbished before you buy. It is the difference between a 3-year and a 90-day warranty.
- ?Tri-fuel only helps if you have a natural gas line and the hookup done by a licensed installer.
- ?Match the model to your loads, not to the starting-watt headline. The running-watt number is the one that holds a fridge.
Buyers who want the quietest possible unit, or who need a dense local service network.
Alternatives to compare
Champion Power Equipment
budgetChampion is the watts-per-dollar play that does not feel like a gamble: $733 buys a dual-fuel storm portable with CO Shield, $1,260 buys tri-fuel with electric start, and no rival matches the 10-year warranty on the aXis standby line. The honest tradeoff is what stands behind it: no dealer-install network, so warranty claims run through a phone queue and service centers instead of a dealer's schedule. That makes Champion ideal for the self-reliant buyer who lines up their own electrician and wants maximum hardware for the money. White-glove buyers who want one company to size, install, and service everything should pay up for a dealer brand instead.
Machine $733 - $5,787
Westinghouse
budgetWestinghouse is the watts-per-dollar play: $1,249 buys 9,500 running dual-fuel watts in the WGen9500DF, roughly half of what Honda charges per watt, and the hardware itself reviews well. Spend the extra $150 on the WGen9500DFc for the CO sensor; that is cheap insurance on a machine that will run next to your house. The honest tradeoff is what happens after the sale: an FTC action over illegal warranty terms and a documented BBB backlog of unanswered claims mean you are betting on the machine, not the support desk. If you want the best spec sheet in the budget dual-fuel class and accept DIY-grade service, buy it. If a warranty you can actually use matters more, pay the Honda premium or look at Champion.
Machine $499 - $3,499
DuroMax
budgetDuroMax is job-site iron pointed at your breaker panel, and at July 2026 prices it is a strong deal: $1,399 for the XP13000HX buys 13,000 peak watts, CO Alert and a 5-year warranty, and $1,499 for the XP13000HXT adds natural gas capability nothing else matches at the price. The tri-fuel HXT is the standout; hook it to the house gas line and storm-week fuel hunting disappears. Plan for the tradeoffs: 200-plus pounds, open-frame noise, and a warranty that ships you parts rather than sending anyone to your driveway. Buy it for the interlock-plus-big-watts use case and treat the 5-year HX warranty as parts insurance, not a service plan.
Machine $549 - $3,499

Methodology
Brand verdicts are based on buyer fit, lane and fuel logic, real machine and installed pricing, warranty terms, service network reach, and the recall and complaint record. A strong reply from a manufacturer can improve factual clarity, but it does not improve placement.
If dealer coverage is thin, the warranty fine print is ugly, or the complaint file is long, we say that plainly instead of hiding it behind marketing copy.
