Best use cases

Choose the Briggs & Stratton 30814 P4500 PowerSmart if you want fewer refueling stops and more set it and forget it running. That 16 hour runtime at 25% load is especially helpful for overnight home backup (fridge, lights, router, fans) or long events where you do not want to babysit the fuel tank. It is also a good fit if you are noise sensitive, since its 60 dB rating is slightly lower than the WEN. The tradeoff is portability: at 104 lb, it is more of a roll it into place generator than something you casually lift into an RV compartment. If you expect to move it frequently, plan on ramps, a second person, or keeping it on a cart.

Choose the WEN 56480iX if your priority is moving it more easily while still getting strong output. At 77 lb, it is notably easier to load into a vehicle, reposition around a campsite, or store between uses. The extra capacity at 4000 running watts and 4800 starting watts can also help with higher starting surges, like some RV air conditioners, power tools, or a larger mix of household loads (within safe, properly connected backup use). The tradeoff is runtime clarity: it is listed at 7 hours at 50% load, but there is no 25% runtime figure provided here, so if long, light load overnight running is your main goal, the Briggs is the safer bet on paper. Noise is still reasonable at 62 dB, but it is a touch louder than the Briggs.

Verdict & recommendation

If your priority is long, steady run time for home backup or all day events, the Briggs & Stratton P4500 is the more confidence inspiring choice thanks to 16 hours at 25% load and a slightly lower 60 dB rating. If your priority is easier transport and a bit more power headroom for mixed loads, the WEN 56480iX makes a strong case with 4000 running watts, 4800 starting watts, and a much lighter 77 lb build.

Both give you inverter style power and the same 3 year warranty, so the decision mostly comes down to how often you move it and whether long runtime or higher output matters more for your typical day.
