Which is better for whole-home backup?

The Jackery HomePower 3600 Plus. It expands to 21 kWh and offers 120V/240V output in parallel, which covers a dryer or water pump. The EcoFlow Delta 3 Ultra tops out at its 3,072 Wh battery.

The Jackery states a 6,000-cycle LFP battery rated for over 10 years and a 5-year warranty. EcoFlow does not publish a cycle rating for the Delta 3 Ultra.

Is the Jackery worth the extra money?

At the lowest recent prices, the Jackery cost about $148 more. That buys roughly 500 Wh more capacity, 240V output, expandability and a stated 6,000-cycle life.

Can either run on propane?

Only the EcoFlow Delta 3 Ultra lists propane as a power source, alongside solar. The Jackery HomePower 3600 Plus is solar only.

Do both deliver the same power?

Yes. Both are rated at 7.2 kW output with a built-in inverter, so the gap is battery capacity and outlet count, not peak wattage.

Which is better for camping?

The EcoFlow is the lighter-duty, lower-cost pick for camping at $1,299.00 at its lowest since November 1, 2026. The Jackery is a home backup unit first, despite its portable design.

The Jackery HomePower 3600 Plus with SolarSaga 500 X has a 3,584 Wh battery, expands to 21 kWh and was $1,447.10 at its lowest since November 2, 2026.
