Frequently Asked Questions

How long does the Delta Pro take to charge?

With standard AC input, it charges 0-80% in 1.8 hours and full in 3.5 hours. Solar charging takes 3-5 hours depending on panel wattage and sunlight.

Can I power my entire house with it?

For essential appliances, yes. For whole-house backup, you'll need 2-3 units plus the Smart Home Panel. It's best for powering essential circuits during emergencies.

Is the 5-year warranty worth it?

Absolutely. Most competitors offer only 2-year warranties. The 5-year coverage demonstrates EcoFlow's confidence in their product quality.
