1,000W solar input and six outlets — the best solar recharge at 1kWh.

$899.00

Overall score 8.1/10

Pros

  • + 1,000W of solar input means a genuine same-day solar recharge, which nothing else at this size manages
  • + Six AC outlets and 56 minutes to full
  • + Expandable to 2,048Wh if your needs grow
  • + Sub-10ms UPS is fast enough for desktop PCs and networking gear

Cons

  • The 3,600W X-Boost figure is voltage reduction, not real surge
  • Only 36W total across both USB-A ports
  • 27.6lb
  • EcoFlow's ecosystem pricing escalates quickly once you start expanding

EcoFlow DELTA 3 Plus review: what the specs say

1,000W solar input and six outlets — the best solar recharge at 1kWh. At $899, EcoFlow's 2024 model sits in the middle of the range — the portable Power Stations we compare run from $249 to $4,799. It scores 8.1/10 overall, calculated from published specifications across 8 categories rather than from a subjective impression.

Its strongest showing is Solar Input at 9.5/10 — maximum solar input and how practical off-grid recharging is. The weakest is Portability at 6.5/10, which is the trade-off to weigh before buying: if that is the specification you care about most, one of the alternatives below will serve you better.

Worth knowing before you buy: the 3,600W X-Boost figure is voltage reduction, not real surge; and only 36W total across both USB-A ports. Every specification on this page comes from EcoFlow's own documentation or a verified retail listing — where a figure is not published, the table says so rather than estimating it.
