Quick answer

Jackery (Explorer 1000 v2), EcoFlow (Delta 2), and Anker SOLIX (C1000) are three of the most-compared 1kWh-class power stations, and each wins on a different axis. Jackery is the lightest by far — about 23.8 lb per Jackery’s own published specs, roughly 9-11 lb lighter than either rival — and its LiFePO4 cells carry the longest cycle-life rating of the three (4,000 to 80% capacity). EcoFlow has the biggest ceiling: the Delta 2 expands to 3,040Wh with an add-on battery and pushes 2,700W of surge output via X-Boost. Anker SOLIX is the fastest to a genuinely full battery — about 58 minutes for a true 0-100% recharge, per Anker’s published specs — and its 5-year warranty applies automatically, while Jackery’s matching 5-year total requires product registration to unlock the final two years. Buy based on which single advantage — weight, expansion headroom, or no-hassle charging speed — matters most for how you’ll actually use it.

Three of the biggest names in portable power, three different bets on what a 1kWh unit should get right. Rather than picking winners in isolation, here’s the full head-to-head using each brand’s flagship 1kWh-class unit: the Jackery Explorer 1000 v2, the EcoFlow Delta 2, and the Anker SOLIX C1000.

Where Jackery wins

Jackery’s edge is weight, and it isn’t close. At about 23.8 lb per Jackery’s own published specs, the Explorer 1000 v2 is roughly 9 lb lighter than the EcoFlow Delta 2 and about 11 lb lighter than the Anker SOLIX C1000 — the clearest reason to pick it if the unit gets loaded in and out of a car, RV, or backpack regularly. Its LiFePO4 cells also carry the longest cycle-life rating of the three, about 4,000 cycles to 80% capacity versus roughly 3,000 for both rivals, a real edge over a multi-year ownership window even though it isn’t the number most buyers check first.

Where EcoFlow wins

EcoFlow’s edge is headroom. The Delta 2 expands to 3,040Wh with an add-on battery — the biggest ceiling of the three — and its X-Boost mode pushes 2,700W of surge output, ahead of the SOLIX C1000’s 2,400W and far ahead of Jackery’s 1,500W continuous rating (Jackery’s 3,000W surge figure looks bigger on paper, but its continuous ceiling is the lowest of the three). If there’s any chance you’ll grow into home backup later instead of buying a second unit, the Delta 2’s expansion path is the most proven — EcoFlow’s modular battery system has been on the market longest of the three brands’ systems. Street pricing has also dropped the furthest of the three, now commonly $349-429 versus its original $699 list.

Where Anker SOLIX wins

Anker’s edge is a faster path to a genuinely full battery and the least hassle on paper. The SOLIX C1000’s roughly 58-minute recharge figure covers a true 0-100% charge, while the Delta 2’s faster-sounding 50-minute number only reaches 80%, and the Explorer 1000 v2 needs about an hour either way. Anker also accepts the highest-rated solar input of the three (600W max, 11-60V MPPT per Anker’s own spec sheet), and its 5-year warranty applies automatically — unlike Jackery’s matching 5-year total, which needs product registration to unlock the final two years.

Anker SOLIX C1000

Best for a fast, no-hassle full charge · $799 list, $399-479 street · 1,056Wh LiFePO4 · 1,800W
  • ~58-minute recharge covers a genuine 0-100% charge, the fastest of the three to full.
  • 600W max solar input, the highest rated of the three.
  • 5-year warranty applies automatically — no registration step required.

The verdict

Buy Jackery (Explorer 1000 v2) if weight and long-term cycle life matter most — it’s the clear pick for anything that gets carried, not just plugged in and left. Buy EcoFlow (Delta 2) if you want the most proven expansion path into home backup and the biggest surge headroom for resistive loads. Buy Anker SOLIX (C1000) if charging speed without a registration step matters most — it’s the only one of the three that reaches a genuine full charge in under an hour with zero extra setup. All three use long-life LiFePO4 cells, so the decision comes down to which single tradeoff — weight, ceiling, or no-hassle speed — fits how you’ll actually use it.
