Best use cases

Choose the WEN 56450i if you plan to use your generator in noise-sensitive environments like campgrounds, tailgates, or RV parks. At 58 dB, it runs about 2 decibels quieter than the P4500, which translates to a noticeable difference when you're parked near neighbors. Its lighter 99.2 lb frame also makes it easier to load into a truck bed or carry short distances, which matters if you're frequently setting up and breaking down. The 3500 running watts will handle most recreational loads comfortably, including a small RV air conditioner, a few lights, a phone charger, and a portable cooler. If you're budget-conscious and want a solid inverter generator that won't break the bank, the WEN is a compelling option.

Choose the Briggs & Stratton P4500 PowerSmart if you need a bit more headroom in your power budget. The 3700 running watts give you extra capacity to run larger appliances or stack more devices without worrying about overload. This makes it a better fit for home backup scenarios where you might need to power a refrigerator, sump pump, and a few lights all at once. The 16-hour runtime at 25% load is particularly appealing for overnight power outages, letting you keep essentials running through the night without refueling. Briggs & Stratton is also a legacy brand in the small engine space, which can make finding parts and service easier in some areas.

Both generators produce clean inverter power safe for sensitive electronics like laptops and phones. Both run on gasoline and carry the same 3-year warranty. The tradeoffs here are genuinely small, so your decision should come down to whether you value the WEN's lighter, quieter profile or the Briggs & Stratton's extra wattage and extended runtime.

Verdict & recommendation

If your priority is portability and quiet operation for camping, tailgating, or RV use, the WEN 56450i is the better fit. It's lighter, a touch quieter, and typically comes in at a competitive price point. If you need more running watts and longer runtime for home backup or powering multiple household appliances during an outage, the Briggs & Stratton P4500 PowerSmart earns its keep with 3700 running watts and that impressive 16-hour runtime at light loads.

Neither generator is a wrong choice here. They occupy nearly the same space in the market, and the differences between them are incremental rather than dramatic. Pick the one that aligns with how you'll actually use it most often, and you'll be well served either way.
