Pros and cons

Best 1 kWh OverallModel DELTA 3 Plus

EcoFlow DELTA 3 Plus Portable Power Station

The most complete 1 kWh station we cover: fast to recharge, strong on solar, and expandable when you need more. Pick it unless weight or a lower budget matters more.

  • Full recharge from a wall outlet in 56 minutes, by EcoFlow's figures
  • 1,000 W of solar input, double the DELTA 2
  • Two 140 W USB-C ports charge most laptops at full speed

Cons

  • At 27.6 lb it is heavier than the Jackery Explorer 1000 v2 and Anker SOLIX C1000 Gen 2
  • Reaching 5 kWh needs extra batteries, sold separately
  • X-Boost runs high-wattage heaters and kettles at reduced power, not at their full rating

What we could not confirm

Anker's regional pages disagree on the C1000 Gen 2's AC outlet count, and Anker ties its warranty term to registration. EcoFlow's outlet count differs by region; the US model has six.
