Specifications side by side

How to choose the right generator

1. Match wattage to load

   Start by calculating the total running watts of your devices. If you only need to charge phones and run a small fan, the WEN 2350W Inverter Generator provides sufficient power. It delivers 2350W and weighs just 39 pounds, making it easy to carry for short trips. For larger loads like RV air conditioners, you need at least 4000W. The WEN 4500W Portable Inverter Generator offers 4500W output, ensuring your sensitive electronics run safely without interruption during your travels.

2. Consider fuel flexibility

   Dual fuel capability adds significant value for extended trips or emergencies. The WEN 4750W Dual Fuel Electric Start Generator allows you to switch between gasoline and propane. This flexibility ensures you can keep running as long as you have fuel, regardless of local availability. Single fuel models like the WEN 4750-Watt Electric Start Generator rely solely on gasoline. While simpler, they require a steady supply of gas. Choose dual fuel if you camp in remote areas or need backup power for multiple days.

3. Check start type needs

   Electric start saves effort, especially for heavier units. The WEN 4750W Dual Fuel and the WEN 4750-Watt Electric Start Generator both feature electric start systems. This means you press a button rather than pulling a recoil cord. This is crucial for the 113-pound WEN 56475, which is too heavy to move manually. Inverter models like the WEN 4500W often use recoil start. If you prioritize ease of use over weight savings, select a generator with electric start.

4. Verify safety features

   Carbon monoxide protection is essential for enclosed or semi-enclosed spaces. The WEN 4500W Portable Inverter Generator includes a CO sensor and automatic fuel shut-off. If dangerous CO levels are detected, the engine stops immediately. This feature is critical for RV camping or tailgating. Other models in this list do not list this specific safety sensor in their attributes. If you plan to use your generator near living spaces or inside an RV, prioritize the model with built-in CO detection for your safety.

5. Evaluate portability constraints

   Weight and dimensions dictate where you can carry your generator. The WEN 2350W Inverter Generator measures 11.5 by 17.5 by 17.3 inches and weighs 39 pounds. It fits easily in a car trunk. In contrast, the WEN 4750-Watt Electric Start Generator weighs 113 pounds and measures 26.6 inches long. It requires a wheel kit for movement. Decide if you need to carry the unit by hand or if it will stay in a garage or workshop. Choose compact inverters for hiking and heavy open-frame units for stationary backup.
