EcoFlow DELTA 3

Now EcoFlow's mainstream 1kWh pick, built on a 3rd-gen LFP pack EcoFlow rates for a 10-year lifespan. 1,800W continuous (2,400W via X-Boost) covers most single appliances — microwave, hair dryer, small power tools — but there's no extra-battery port, so 1,024Wh is the ceiling.

EcoFlow RIVER 3 Plus

The RIVER 3 Plus replaces the RIVER 2 as EcoFlow's small grab-and-go unit — a touch pricier but with X-Boost surge to 1,200W and genuine expandability via EB300/EB600 batteries. Not for kettles or big appliances, but excellent for devices and camping.
