  EcoFlow DELTA 3 family

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

  Several boxes wear the DELTA 3 badge. The plain DELTA 3, the Plus and the Classic hold the same battery at three prices. Judged against a refrigerator for an 8-hour working-day outage, the EcoFlow DELTA 3 Classic (1024Wh) is the default buy for a typical fridge, unless you will add a battery.

  Buy the EcoFlow DELTA 3 Classic (1024Wh).

  Home-backup class

  The home-backup class: DELTA Pro 3, SOLIX F3800 Plus, 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 82 units we track, 20 cover that day on the best case and none covers it on the worst, these three included.

  It has the higher continuous and surge rating of the two picks that have one, and it takes the most extra batteries; take the EcoFlow DELTA Pro 3 if you would rather start with more nominal capacity in the box itself, and the Jackery Explorer 5000 Plus if you want the most battery and the most output on this table and will go and find the price yourself.

  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, above all the solar inputs.

  Buy the Anker SOLIX F3800 Plus.

• 
  1000 v2 vs 1000 Plus

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

  Two Jackerys one word apart. The 1000 Plus holds a little more, enough to carry an old, big fridge through 8 hours, and it takes add-on packs. The 1000 v2 does neither. Which you want depends on your fridge and on whether you will ever buy a pack.

  Buy the Jackery Explorer 1000 v2 if your fridge is typical.
