• Westinghouse iGen5000c lasts up to 18 hours at 25% load, great overnight.
• Westinghouse iGen5000c provides 3900 running watts and 5000 starting watts.
• WEN 56450i delivers 3500 running watts and 4500 starting watts for essentials.
• WEN 56450i weighs 99.2 lb, lighter than iGen5000c at 105.8 lb.
• Both are gasoline inverter generators with a 3 year warranty.

Best use cases

Choose the WEN 56450i if you want a capable inverter generator for occasional home backup and you do not need marathon runtime. With 3500 running watts and 4500 starting watts, it is well suited to keeping essentials going like a refrigerator, lights, Wi-Fi, and battery chargers, especially if you manage loads (for example, not running a microwave and a space heater at the same time). It is also a reasonable fit for tailgates and weekend camping where you run it in blocks of time rather than all night. At 99.2 lb, it is still heavy, but it is a bit easier to move than the Westinghouse, which matters if you are lifting it into a truck bed or rolling it around a garage. The tradeoff is that the listed runtime at 50% load is 8.5 hours, so for longer outages you should expect more frequent refueling and more planning.

Choose the Westinghouse iGen5000c if your priority is longer, quieter operation and a little more power headroom. Its 52 dB noise rating is notably lower than the WEN’s 58 dB, which can be the difference between “background hum” and “noticeable” when you are trying to sleep, camp near neighbors, or run it outside an RV. The big practical win is endurance: up to 18 hours at 25% load and 15 hours at 50% load means fewer refuels and better overnight coverage. With 3900 running watts and 5000 starting watts, it is also the safer bet for higher starting surges, like an RV AC compressor or a fridge plus another motor load. The tradeoffs are extra weight at 105.8 lb and typically a higher buy in for the longer runtime and quieter operation.

Verdict & recommendation

If your priority is long runtime and lower noise for overnight use, RV trips, or extended outages, the Westinghouse iGen5000c is the more comfortable generator to live with, thanks to 18 hours at 25% load and a 52 dB rating. If your priority is a solid inverter generator for shorter backup windows, lighter handling, and straightforward essentials power, the WEN 56450i still covers a lot with 3500 running watts and 4500 starting watts.

Both give you inverter safe power and a 3 year warranty, so neither is a risky pick on paper. The practical choice is whether you value fewer refueling stops and quieter operation (Westinghouse) or you are fine refueling more often to save some weight and keep things simpler (WEN).
