Portable Power Stations / EcoFlow
EcoFlow DELTA 3 Plus
1,000W solar input and six outlets — the best solar recharge at 1kWh.
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.
