Our DuroMax verdict
DuroMax 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.
DuroMax sells direct at duromaxpower.com under a near-permanent was/now sale, so the sale price is the real price; in July 2026 the XP13000EH ran $1,299 against a $1,699 list. The step-ups are cheap: $100 more buys the XP13000HX at $1,399 with CO Alert, a digital panel and the 5-year warranty, and another $100 buys the tri-fuel XP13000HXT at $1,499 (list $2,199) that also runs on home natural gas. The XP open-frame range spans $549 for the XP4850EH up to $3,499 for the 15,000-watt tri-fuel EFI unit, and the quiet low-THD iH inverter line starts at $649 for the XP2300iH and runs $1,999 for the XP9500iH. Hookup gear sells on the same site at public prices: Reliance Pro/Tran manual transfer switches run $299 to $579 depending on amps and circuits, power inlet boxes $32 to $85 (the 50A XP50PB is $79.99), and through-the-wall kits $130 to $224. Orders over $199 ship free, and the same machines sell at Home Depot, Lowe's and Amazon at public prices that track the direct sale numbers.

Strengths & considerations
What it does well
- +13kW-class dual-fuel and tri-fuel for under $1,500 on sale
- +5-year residential warranty on HX/HXT lines beats the budget field
- +50A outlet and MX2 switch make whole-panel interlock hookups simple
Where it falls short
Sourced, not our opinion. This is the part the brand's own page leaves off.
BBB shows unanswered complaints (not BBB accredited) and review sites log slow or no response on parts and warranty repairs; complainants note coverage pays for parts, not service calls.
Source: BBB profile; Trustpilot and PissedConsumer reviews
The 13kW class weighs well over 200 pounds and runs far louder than any inverter; fine on a job site, a lot of generator to wheel out and live next to in a week-long outage.

Before you buy: confirm these
These are DuroMax's own documented terms and open questions, not our test results. Get the specifics in writing on the quote before you order.
- ?The volume-selling XP13000EH has no CO shutoff; CO Alert only comes on the DX, HX and HXT lines, roughly $100 to $400 more at July 2026 prices. Verify the model suffix before buying.
- ?The 5-year warranty applies only to HX, HXT, iH and iHT models, and even there the XP2300iH, XP4500iH and XP9000iH are carved back to 3 years; everything else is 3-year residential. Confirm your exact model's term on the warranty page.
- ?The warranty text excludes freight, loss of time and incidental costs, with no service-call provision; assume shipped parts and your own wrench, and check the authorized service center locator for your zip code before you buy.
- ?Open-frame XP generators are not low-THD machines; DuroMax reserves its Low THD marketing for the iH and iHT inverter lines, so confirm the THD spec before feeding computers or other sensitive electronics.
Anyone who wants quiet, light or hand-holding support; this is job-site iron pointed at a house.
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
Predator
budgetPredator gives you more starting watts per dollar than anything else that is not a no-name marketplace listing, and CO shutoff is standard across the range. Then the warranty ends after 90 days, against three years from Honda, Champion and Firman. That is not a detail, it is the tradeoff. Buy it if the price difference matters more to you than support in year two, and buy it near a store.
Machine $780 - $1,650

Support runs direct from California via 1-844-DUROMAX and email with a thin authorized service center network; BBB complaints describe slow responses, and the warranty explicitly excludes freight and loss-of-time costs.

Direct phone and email support from California with sparse authorized service centers; plan on shipped parts and DIY-friendly repairs rather than house calls.

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.
