Its price is $0.565 per Wh. The EcoFlow DELTA 3 Classic is $479 at $0.468 per Wh. The Jackery HomePower 1000 v2 is $559 at $0.546 per Wh. It matches the Classic at 1,024 Wh and 1,800 W, and adds expansion to 5,000 Wh, 4,000 cycles and 6 outlets for $100 more.

It ranks #17 of 18 expandable, #49 of 50 solar, #46 of 53 lightweight, #31 of 39 UPS, #11 of 43 fast charging. Warranty is not stated as a standard term; the page says only 5 years. Its price is a sale price, with a higher list price shown on EcoFlow's page.

Buy it if you want to grow to 5 kWh later. Skip it if you will never expand, since the Classic is $100 cheaper.
