Generac #7247 XT8500EFI vs DEWALT DXGNR8000

Comparison Overview

Key takeaways

• Generac #7247 XT8500EFI delivers 8500 running watts and 10000 starting watts.
• DEWALT DXGNR8000 provides 8000 running watts with the same 10000 starting watts.
• DEWALT is lighter at 183 lb, Generac weighs 214 lb for more output.
• Both are gasoline, non-inverter generators aimed at home backup and job sites.
• Both list 9 hours runtime at 50% load and include a 3-year warranty.

Best use cases

Choose the Generac #7247 XT8500EFI if you want the most running power between these two for home backup or heavier tools. With 8500 running watts and 10000 starting watts, it is better suited to situations where multiple loads may overlap, like a refrigerator and freezer cycling while you also run a sump pump, lights, and a microwave. It is also a sensible pick if you tend to run closer to the generator’s limit for extended periods, since the extra 500 running watts can reduce how often you have to manage loads. The tradeoff is portability, at 214 lb it is more of a roll-it-into-place generator than something you will want to lift or reposition frequently.

Choose the DEWALT DXGNR8000 if you want similar starting capability in a package that is easier to move and store. It still provides 10000 starting watts for startup surges, and 8000 running watts is plenty for many backup setups and job site needs, especially if you are comfortable staggering big loads. At 183 lb, it is notably less of a chore to maneuver around a garage, trailer, or job site. The tradeoff is that you have a bit less continuous headroom, so if you plan to run several high-draw items at once, you may need to be more intentional about what is on.

For camping and RV use, both are generally a tougher fit because they are non-inverter models and typically louder and bulkier than inverter options. If your priority is quiet operation or cleaner power for sensitive devices, you would usually look at an inverter generator instead of either of these.

Verdict & recommendation

If your priority is maximizing continuous output for a more demanding home backup load plan, the Generac #7247 XT8500EFI is the better match thanks to 8500 running watts. If your priority is easier handling with nearly the same surge capability, the DEWALT DXGNR8000 makes more sense at 183 lb while still offering 10000 starting watts.

Because both are gasoline, non-inverter generators with the same 9-hour runtime at 50% load and a 3-year warranty, the decision mostly comes down to whether you value extra running headroom (Generac) or easier portability (DEWALT). Pick the one that best fits how often you will move it and how close to the limit you expect to run.
