The EcoFlow DELTA 3 1500 is a 1,536 Wh portable power station that combines a fairly large mid-range battery with a compact 16.5 kg body and an IP54 housing. Its four Type F outlets deliver 1,800 W of pure sine power with peaks up to 3,600 W and X-Boost up to 2,400 W, enough for around 99% of common household appliances from fridges to hair dryers. UPS switchover in under 15 ms protects sensitive equipment during outages, and the pack is quiet: 35 dB at loads below 600 W and 45 dB up to 1,200 W. LiFePO4 cells rated for 4,000 cycles to 80% capacity make it a genuinely long-life battery.
