EcoFlow typically has 2-3 big sales events a year where they offer products at a deep discount. They are having a flash sale for the next 10 hours on the Delta 1300 for $750. At this price, there is nothing of comparable size except a couple of Chinese brands. The Delta 1300 is one of their 1st generation products, it does not have the LiFePO4 chemistry used in later generations, so its listed 800 lifecycles to 80%. If that's acceptable, it's otherwise a great power station. I bought this model when it was introduced, almost two years ago. It performed flawlessly, I merely outgrew it.
