Head to head on value

Average cost per watt-hour across each brand’s tracked range, and the winner in each capacity band. This is a value comparison only — it says nothing about support, app quality or build, which we cannot measure from a spec sheet.

What each brand will not tell you

EcoFlow’s known weaknesses

  • The ecosystem is the product — accessories are priced accordingly
  • App dependency for features buyers may expect on the device
  • Line-up churn means similar names differ a lot between generations
  • Support experience is a recurring complaint in independent coverage

Goal Zero’s known weaknesses

  • Capacity per dollar is generally behind the value brands
  • Recharge speeds and solar input can trail the newer competitors
  • Generations vary a lot — an older Yeti and a newer one are not comparable
  • Line-up has churned, which complicates comparisons across years
