Jackery Explorer 300 Plus vs EcoFlow RIVER 2 Max
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
These two cost the same, so the decision comes down to what you're powering.
- EcoFlow RIVER 2 Max holds 78% more energy (512Wh vs 288Wh), so it runs the same load proportionally longer.
- EcoFlow RIVER 2 Max has 400W more surge headroom (1000W vs 600W) — that decides whether a fridge, pump or AC compressor will actually start.
- Jackery Explorer 300 Plus is 4.9 lb lighter (8.27 lb vs 13.2 lb).
We'd skip the Jackery Explorer 300 Plus in this matchup. It costs $0 more than the EcoFlow RIVER 2 Max while matching or trailing it on capacity, surge and cycle life — there's no spec here that justifies the premium.
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
Double the River 2's capacity and output for $100 more. The sweet spot of EcoFlow's small line for anyone eyeing the occasional small appliance.
Best for: Campers who want headroom over a pure device charger without the size of a 1kWh unit.
Where it falls short:
- Still not enough output for heaters or compressors
- 220W solar input is modest
