Our take on the EF EcoFlow DELTA 3 Classic Portable Power Station

The EcoFlow DELTA 3 Classic is a 1,024 Wh portable power station with a 1,800 W AC output that X-Boost can push to 2,600 W for resistive loads like kettles and space heaters. It uses LiFePO4 cells rated for thousands of cycles, charges to 80% over AC in about 45 minutes, and switches to battery in under 10 ms as a UPS. It suits campers, van and RV owners, and anyone who wants a mid-size home backup unit. Against the DELTA 2 it adds a higher base output and faster charging; it is heavier and pricier than 500–600 Wh rivals, and X-Boost will not run every high-draw appliance.
