EF ECOFLOW DELTA 4 3000+AC Portable Power Station

EF ECOFLOW DELTA 4 3000+AC is a battery-powered portable power station listed with 3,072 watt-hours of energy capacity. Its stated 3,600-watt continuous AC output and 7,200-watt surge rating are aimed at home backup and mobile power, while the listing also promotes solar, alternator and generator recharging.

At a glance

The listing gives both a 3,000-watt output specification and a separate claim of 3,600W continuous AC output with 7,200W surge. Confirm which figure applies to the exact configuration before planning loads.
The claimed 3,072Wh capacity is intended for longer-duration backup than smaller portable batteries, though actual runtime depends on connected equipment and use.
Four charging methods are claimed: AC wall, solar, alternator and generator.
The listing claims a refrigerator runtime of up to 58 hours and a full recharge in 118 minutes. These are manufacturer claims, not independently verified results.

What to know before buying

Listing details to confirm

Listing details are inconsistent: the specification table states 3000 watts output, while feature text claims 3600W continuous AC output and 7200W surge. The 3072 watt-hours capacity is energy, not output power. Confirm the applicable output rating and exact model configuration before purchase. Runtime, charging speed and other performance figures are manufacturer claims and can depend on operating conditions.
