Jackery Explorer 300 Plus vs EcoFlow RIVER 2
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
EcoFlow RIVER 2 costs $100 less. Whether that gap is worth closing depends on what you need to run.
- Jackery Explorer 300 Plus holds 13% more energy (288Wh vs 256Wh), so it runs the same load proportionally longer.
- EcoFlow RIVER 2 is 0.6 lb lighter (7.7 lb vs 8.27 lb).
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.
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
The cheapest way into LiFePO4. 256Wh is a device charger, but at under $200 with a 60-minute recharge it's hard to argue with.
Best for: Budget campers who just need to keep phones, cameras and a laptop alive.
Where it falls short:
- 300W output runs devices only
- 256Wh is a single evening of real use
