A-iPower SUA10000EC vs Firman P08008
Compare A-iPower SUA10000EC vs Firman P08008: both hit 10,000 starting watts, but Firman runs longer, quieter, and adds a 3-year warranty.
- A-iPower SUA10000EC
- Firman P08008
Comparison Overview
Runtime is the biggest real-world separator here. The Firman P08008 is rated for 12 hours at 50% load, while the A-iPower SUA10000EC lists 7 hours at 50% load, which can mean fewer refueling breaks during an outage or long workday.
Power output is very close. Both deliver 10,000 starting watts, and the A-iPower edges ahead on continuous output with 8,200 running watts versus 8,000 running watts on the Firman. That small gap can help if you are stacking several loads at once, but for most home backup setups, they will feel similar.
Neither is an inverter generator, so expect traditional generator sound and power quality. The Firman is a bit quieter at 74 dB compared with 77 dB for the A-iPower, and it is slightly lighter at 208 lb versus 216 lb. Warranty also favors Firman at 3 years vs 2 years.
Pick the Firman if longer runtime, slightly lower noise, and longer warranty matter most, and lean A-iPower if you want a touch more running wattage headroom.
Key takeaways
- Both deliver 10,000 starting watts for handling big motor start-up surges.
- Firman P08008 runs 12 hours at 50% load, A-iPower SUA10000EC runs 7 hours.
- A-iPower SUA10000EC provides 8,200 running watts vs 8,000 running watts on Firman.
- Firman is slightly quieter at 74 dB compared with A-iPower at 77 dB.
- Firman weighs 208 lb, A-iPower weighs 216 lb, both are heavy to move.
- Firman includes a 3-year warranty, A-iPower includes a 2-year warranty.
Best use cases
Choose the A-iPower SUA10000EC if you want the most continuous power of the two for demanding, mixed loads. With 8,200 running watts and 10,000 starting watts, it is a solid fit for home backup where you may be running a refrigerator or freezer, sump pump, lights, and a few outlets at the same time, especially if you are trying to avoid constantly juggling what is on. It can also make sense for a job site where you want a little extra cushion for motor starts. The tradeoff is convenience: the listed 7-hour runtime at 50% load means more frequent refueling on longer outages, and at 77 dB it is on the louder side for neighborhoods.
Choose the Firman P08008 if you value longer stretches between fill-ups and a slightly more comfortable ownership experience. Its 12-hour runtime at 50% load is a big advantage for overnight outage coverage or long workdays when you do not want to refuel as often. It is also a bit quieter at 74 dB and a bit easier to move at 208 lb. Power is still strong at 8,000 running watts and 10,000 starting watts, which is plenty for many home backup setups, but if you are right on the edge with multiple large motor loads, the A-iPower’s extra 200 running watts may be reassuring. Neither model is ideal for camping or RV use due to weight, noise, and non-inverter power, but both can work for occasional remote power where portability is not the priority.
Verdict & recommendation
If your priority is fewer refueling stops during an outage, the Firman P08008 is the easier generator to live with thanks to its 12-hour runtime at 50% load, slightly lower 74 dB noise rating, and 3-year warranty. If your priority is squeezing out a bit more continuous capacity for stacked loads, the A-iPower SUA10000EC offers 8,200 running watts while matching the same 10,000 starting watts.
In practice, choose Firman for longer, steadier coverage and ownership peace of mind, and choose A-iPower when that small extra running-watt margin matters for your load plan.

| Summary | The A-iPower SUA10000EC is an 8200-watt gasoline generator built for home backup and job site power. Its 10000-watt peak capacity means it can start large appliances like air conditioners and compressors that demand high inrush current. Once running, the 8200-watt sustained output powers multiple devices simultaneously, making it suitable for extended outages or construction work where you need both initial surge capacity and steady load handling.
At 216 pounds, this unit is stationary by nature. A-iPower includes a wheel kit in the box, which transforms the weight from a dead-lift problem into a roll-behind solution. The 7-gallon fuel tank runs for 7 hours at half load, meaning a typical job site or home backup scenario requires refueling once daily. The 77 dB noise level is moderate for this wattage class, placing it in the range where outdoor operation is acceptable but indoor use near sleeping areas would cause disruption. | The Firman P08008 is an 8,000-watt gas generator built for job sites, emergency backup, and outdoor events where sustained power matters more than portability. At 8,000 running watts and 10,000 peak watts, this unit can run a refrigerator, microwave, and power tools simultaneously, or handle the electrical load of a small RV. The 439cc cast-iron-sleeve engine burns gasoline, a fuel readily available at any gas station, and runs for 12 hours at half load on an 8-gallon tank. This runtime window means a single refueling cycle covers an overnight power outage or a full day of outdoor work. |
