Comparison Overview

Key takeaways

• Both deliver **3650 running watts** and **4550 starting watts** on dual fuel.

• Both list **14 hours runtime at 50% load** for longer outage coverage.
• Noise is similar, Firman **67 dB** vs Champion **68 dB**.
• Both are non-inverter generators, better for tools and backup than quiet camping.
• Both include a **3-year warranty** for comparable long-term coverage.

Best use cases

Choose the Firman H03655 if you expect to move the generator often. At 112 lb, it is noticeably easier to maneuver than a 127 lb unit when you are rolling it out for a storm, repositioning it to manage exhaust direction, or lifting it into a vehicle for a job site. It is also a sensible pick for typical home backup on a budget when you want dual-fuel flexibility, for example running propane for cleaner storage and easier long-term fuel management, then switching to gasoline when you need maximum availability.

The tradeoff is that it is still a non-inverter generator, so it is not ideal for sensitive electronics or for places where quiet operation matters. You can still run many household items safely, but you will want to avoid treating it like a silent RV or camping unit.

Choose the Champion Power Equipment 201504 if you are buying based on brand familiarity, parts availability, or you already own Champion accessories and prefer to stay in that lane. Performance is essentially the same as the Firman at 3650 running watts and 4550 starting watts, with the same 14-hour runtime at 50% load and a 3-year warranty, so it fits the same core scenarios: emergency home backup, driveway power for tools, and occasional remote work.

The tradeoff is the extra weight, which matters most if you are frequently transporting it or moving it around solo. Like the Firman, it is not the best match for quiet camping or RV parks where inverter generators are usually the better fit.

Verdict & recommendation

If your priority is easier handling and transport, the Firman H03655 is the more practical choice simply because it is 15 lb lighter while delivering the same 3650 running watts and 4550 starting watts. If your priority is sticking with a brand you trust, or you value Champion’s broad market presence and prefer buying into that support channel, the Champion Power Equipment 201504 is a reasonable pick with nearly identical real-world performance.

Either way, you are choosing a dual-fuel, non-inverter generator with similar noise (67 to 68 dB) and the same 3-year warranty, so plan your decision around how often you will move it, where you will run it, and whether you need inverter-level quiet and clean power. Pick the one that best matches your handling needs and brand comfort, since the power output is effectively a tie.
