Usability

8.0 out of 10

It stores 3,600 Wh, the top of the large tier, so it scores 10 on capacity; CNET drew 3,328 Wh of it on AC, 92 percent of rated, while OutdoorGearLab drew 82 to 85 percent.

Its inverter is rated 3,600 W continuous and 7,200 W surge at 120 V, so it scores 10 on power output.

A full charge takes about 2.7 hours from a 120 V outlet, though solar input reaches 1,600 W, so it scores 4 on recharging.

EcoFlow rates the cells for 3,500 cycles to 80 percent capacity, so it scores 6 on battery life.

It switches to battery within 30 ms, takes two extra batteries to 10.8 kWh and works with EcoFlow's Smart Home Panel 2 through the Double Voltage Hub, so it scores 7 on backup readiness.

SGS lists it to UL 2743 and UL 1973 by model, so it scores 8 on verification.

EcoFlow's policy gives it 2 years plus 3 on registration, so it scores 8 on warranty and support.

Warranty and returns

Its warranty runs 5 years on most stations, or 3 years plus 2 on registration, with returns within 30 days.

3.6 kWh from 2021, 240 V only with two units

The DELTA Pro is EcoFlow's 2021 3.6 kWh LiFePO4 station on wheels, a 99 lb unit with a 30 A RV outlet.

Verdict

It suits a buyer who wants the most capacity in one 120 V unit and can move 99 lb, or who plans to pair two for 240 V. $1,899 at us.ecoflow.com.

About

We compare products properly: every one scored against published criteria, with what independent sources actually say kept separate from our own assessment.

The method is published so you can see what a score means. Where evidence is missing, the page says so rather than showing an invented number.
