EcoFlow RIVER 3 vs EcoFlow RIVER 3 Plus

Technical comparison · Ultraportable

In brief

Between the two sizes in the same line, the choice comes down to how long you want the battery to last and how much power you need on tap: the Plus doubles continuous output and more than doubles cycle life over the base model.

The differences that matter

  • Continuous output: 300 W vs 600 W → the Plus runs appliances the base model can't sustain continuously.
  • Battery cycle life: 730 vs 1825 → the Plus absorbs far more recharges before losing capacity.
  • Warranty: 2 years vs 5 → much longer coverage for the Plus.
  • Maximum solar input: 110 W vs 220 W → the Plus recharges from solar much faster.

Which one to choose

Choose EcoFlow RIVER 3 if…

Pick the base RIVER 3 if light loads up to 300 W are enough and you want the more compact of the two (3.5 kg vs 4.7). You accept a shorter warranty (2 years vs 5) and a battery rated for fewer recharges over time (730 declared cycles vs 1825).

Choose EcoFlow RIVER 3 Plus if…

Pick the RIVER 3 Plus if you need to run appliances up to 600 W continuously and expect to use it often over the years: declared cycle life rises to 1825 and the warranty reaches 5 years. In exchange you carry about 1.2 kg more.
