The models people weigh against each other

• 
  EcoFlow DELTA 3 family

  Which EcoFlow DELTA 3? The whole family, judged against one plan

  Several boxes wear the DELTA 3 badge, and more than one of them holds the same battery behind a different price. Judged against a refrigerator for an 8-hour working-day outage, the EcoFlow DELTA 3 Plus is the default buy in this family.

  Buy the EcoFlow DELTA 3 Plus unless you know you do not need its wider solar input, or you are sizing for something longer than a refrigerator for an 8-hour working-day outage.

• 
  1 kWh class

  The one-kilowatt-hour class: Jackery 1000 v2, Anker C1000, EcoFlow DELTA 3

  These three hold near enough the same battery, so the thing that separates them is whether your refrigerator's compressor gets going on the first try.

  Buy the Jackery Explorer 1000 v2 unless you plan to add a battery later, in which case buy the Anker SOLIX C1000 instead.

• 
  Home-backup class

  The home-backup class: DELTA Pro 3, SOLIX F3800, Explorer 5000 Plus and the rest

  The biggest boxes you can buy without calling an electrician, judged against a refrigerator, Wi-Fi, a few LED lights and phone charging for 24 hours. Of the 58 stations we track, 29 cover that day on the best case and none covers it on the worst, these three included.

  Buy the Anker SOLIX F3800.

• DELTA 3 vs DELTA 2

  EcoFlow DELTA 3 vs DELTA 2: what changed, and which one to buy

  The same battery, a generation apart: the EcoFlow DELTA 2 (EFD330) and the EcoFlow DELTA 3 hold identical capacity behind different inverters, inputs and expansion ports. This page is about what EcoFlow changed, and whether the older box is still the one to buy.

  Buy the EcoFlow DELTA 3: it is the current generation, it carries a verified listing, and in the listings we checked it is the cheaper of the two at $629 against the EcoFlow DELTA 2 (EFD330)'s $699.

• 
  F3800 vs F3800 Plus

  Anker SOLIX F3800 vs F3800 Plus: the real differences

  Two power stations that share a name, a product page, a battery and an inverter. What separates them is the way power gets in, and whether there is a listing we can verify.

  Buy the Anker SOLIX F3800: it is the one with a verified listing, at $2,200, and it carries the same battery and the same continuous and surge output as the Anker SOLIX F3800 Plus in our record.

• 
  1000 v2 vs 1000 Plus

  Jackery Explorer 1000 v2 vs 1000 Plus: the expandable one or the cheaper one

  Two Jackerys one word apart, holding near enough the same battery, except that one of them takes add-on packs and the other cannot. Which you want comes down to whether you will ever buy the pack.

  Buy the Jackery Explorer 1000 v2 unless you expect to add a battery, in which case the Jackery Explorer 1000 Plus (JE-1000C) is the box built for it, with the caveat that we found no verified listing for the bare unit and so cannot tell you what it costs.

• 
  1000 v2 vs C1000 Gen 2

  Jackery Explorer 1000 v2 vs Anker SOLIX C1000 Gen 2

  Two boxes holding near enough the same battery: one is lighter and has a listing we could verify, the other is rated higher and refills quicker. Which of those you need depends on what you plug into it.

  Buy the Jackery Explorer 1000 v2 if the weight matters, or if you want to order today from a listing we checked ourselves at $559.
