Choosing the Right Yeti Electric Generator
Capacity & Power Output
The most crucial factor when selecting a Yeti electric generator is understanding your power needs. Capacity, measured in Watt-hours (Wh), determines how long the generator can run your devices. Power output, expressed in Watts (W), dictates what devices you can run simultaneously. A higher Wattage is needed for appliances with motors (refrigerators, power tools) which require a surge of power when starting. Consider the continuous wattage requirement of your devices and ensure the Yeti generator can meet or exceed it. If you plan to power multiple devices at once, add up their wattage requirements. For example, the Yeti PRO 4000 boasts a 3600W continuous output, ideal for running most home appliances, while the Yeti 500 with 500W is better suited for smaller electronics. Choosing a generator with significantly more capacity than you currently need provides a buffer for future needs and extends the generator’s lifespan by reducing the depth of discharge.
