FlexPower 4500ies Inverter Generator vs PowerSmart PS5046CE Inverter Generator

Both are 120V inverter generators with electric start and a 30A RV outlet, so the choice comes down to noise, safety and output. The FlexPower 4500ies is the quieter unit at under 63 dB and is lighter at 82 lb, which matters for campgrounds and national forest rules. The PowerSmart PS5046CE adds a CO sensor with automatic shutdown, USB and 12V DC ports, and slightly more running watts. Owners of both rate them 4.8 out of 5, but PowerSmart buyers report more noise and heavier weight, while FlexPower buyers praise the quiet running and easy transport.

• Choose the FlexPower 4500ies if you camp in quiet hours or national forests, want the lighter unit to wheel around, and value low noise over extra outlets.
• Choose the PowerSmart PS5046CE if you want a CO shutdown safety system, USB and 12V charging ports, and a bit more running power for RV appliances.
