The EcoFlow DELTA 3 Plus is a 1024Wh portable power station built on third-generation LiFePO4 (LFP) battery chemistry, delivering 1800W of AC output with 3600W surge capacity and support for up to 13 simultaneous output ports. X-Boost technology extends compatibility to appliances drawing up to 2200W, enabling use with ovens, hair dryers, kettles, and other high-draw devices that would otherwise exceed the rated output.
The unit supports five charging methods: AC wall charging at up to 1500W for a full charge in 56 minutes, dual MPPT solar input accepting up to 1000W (500W x2) for a full charge in approximately 70 minutes, 800W car charging for a full charge in 1.3 hours, hybrid AC plus solar, and compatibility with EcoFlow's Smart Generator 3000 for automated overnight replenishment. Output ports include 6 AC outlets, 2 USB-A fast charge ports (36W max), 2 USB-C ports (140W max each), 1 car power port (126W max), and 2 DC5521 ports. A built-in UPS function provides switchover in under 10 milliseconds, making it suitable for protecting sensitive equipment like NAS servers and desktop computers.
The battery pack is IP65-rated for dust and water splash resistance. Rated for 4000 charge cycles to 80% capacity, the DELTA 3 Plus is designed for approximately 10 years of regular use. Capacity can be expanded up to 5kWh by connecting compatible extra battery packs (DELTA 3, DELTA 2, DELTA 2 Max, or DELTA Pro 3 Extra Batteries) via an Alternator Charger XT150 Output Cable. The unit measures approximately 16 x 8.0 x 11 inches and weighs 27.6 lb. Noise output remains under 30 dB at loads below 600W. Compatible with the EcoFlow app for time-of-use scheduling and storm warning alerts. Backed by a 5-year warranty.
