EcoFlow DELTA 3 Plus Review: Fast Charging at 1 kWh
Verdict
3.9/5
The DELTA 3 Plus suits people who want a 1 kWh LFP station that recharges quickly and can grow later: 1,024 Wh, 1,800 W continuous and a 56-minute AC charge to 100%. Its main limitation is price per Wh, which is the highest of the 1 kWh stations we track at the reference prices of Oct 11, 2026.
Best for: Fast top-ups between outages; Buyers who may add capacity later; Larger solar setups
Skip if: You want the lowest price per Wh; Weight matters more than charging speed

Who is it for?
The DELTA 3 Plus is aimed at people who want a 1 kWh station that refills fast and has headroom to grow. EcoFlow rates it at 56 minutes from 0 to 100% on AC, which is only beaten among the 1 kWh stations we track by the Anker SOLIX C1000 Gen 2 at 49 minutes. It is a poor fit if the lowest price per Wh is the goal.
Battery and output
The pack holds 1,024 Wh of LFP chemistry, which EcoFlow rates for 4,000 cycles (to 80% or more). Continuous AC output is 1,800 W with a 3,600 W surge rating, and EcoFlow lists a switchover time of 10 ms or less for UPS-style use. It weighs 12.5 kg, about 82 Wh per kg.
Charging and solar
Beyond the 56-minute AC charge, solar input tops out at 1,000 W (two 500 W inputs), the highest solar rating among the 1 kWh stations we track. Extra batteries can extend the system to a larger capacity, up to 5 kWh according to EcoFlow’s page.
Ports
Six AC outlets, two USB-C, two USB-A and one car outlet. Plenty of AC sockets means a desk, a router and a few appliances can share one unit.
How it compares
Reference price on Oct 11, 2026: $719 in the US store (a promotional price that day; regular price $799). The UK and EU versions have a different outlet layout, so we list the US model only. At the US price that is about $0.70 per Wh, higher than the Jackery Explorer 1000 v2 at about $0.47 per Wh, the Anker SOLIX C1000 Gen 2 at about $0.49 per Wh and the BLUETTI AC180 at about $0.43 per Wh on the same date. Those three accept less solar input (400 W to 600 W) and none of them is expandable. The DELTA 3 Plus gives up price for speed, solar headroom and expandability. See all stations on the power station list and estimate runtime with the runtime calculator.
What to watch out for
Prices change with promotions, so treat the figures above as a dated snapshot. As of Oct 11, 2026 the US listing was a pre-order with shipping expected in November. To connect any power station to house wiring, use a transfer switch installed by a qualified electrician. This review is based on published specifications, not hands-on testing.
