EcoFlow DELTA 3 Plus Portable Power Station

EcoFlow · DELTA 3 Plus

About 1 kWh of LiFePO4 storage with the output to handle a fridge compressor at start-up, and room to expand with extra batteries.

The DELTA 3 Plus sits at the point where a battery stops being a phone charger and becomes household backup. Its 1,024 Wh capacity covers a fridge-led day plus lights and the router, and its 3,600 W surge rating handles the start-up draw of a fridge compressor. It recharges fully from the wall in under an hour, so it can be topped up between outages, and it is the only unit in this group that expands with extra battery packs for households that later want longer coverage.

What it does well

  • Surge headroom for a fridge compressor
  • Expandable as your plan grows
  • Very fast wall recharge

Trade-offs
