Jackery Explorer 300 Plus vs EcoFlow RIVER 3 Plus

Side-by-side on the specs that decide it — surge, capacity, runtime and price.

Both models' specs verified against manufacturer listings · Last updated

The short answer

Jackery Explorer 300 Plus costs $30 less. Whether that gap is worth closing depends on what you need to run.

⚠️ Before you buy

Neither of these will start a sump pump or well pump — both surge below the ~3,400W those motors need. If home backup with pumps is your use case, look at higher-surge models instead of either of these.

Jackery Explorer 300 Plus

A device charger, not a power station. At 8.27 lb and 288Wh it's for phones, laptops and a CPAP — nothing with a heating element or compressor.

Best for: CPAP users and travelers who need days of small-device power in a bag.

Where it falls short:

  • 300W output rules out almost every appliance
  • 288Wh is a single laptop-day of capacity
EcoFlow RIVER 3 Plus

Doubles the River 3's output for $90 more, and adds an expansion battery port. The better buy of the two unless weight is everything.

Best for: Campers who want one unit that covers devices plus the occasional small appliance.

Where it falls short:

  • 286Wh alone is a single evening of real use
  • 220W solar input is modest
