EcoFlow RIVER 2 Pro vs Allpowers R1500
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 Pro costs $100 less. Whether that gap is worth closing depends on what you need to run.
- Allpowers R1500 holds 50% more energy (1152Wh vs 768Wh), so it runs the same load proportionally longer.
- Allpowers R1500 has 1400W more surge headroom (3000W vs 1600W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow RIVER 2 Pro is 20.5 lb lighter (17 lb vs 37.5 lb).
- Allpowers R1500 is rated for 3,500 cycles vs 3,000 — meaningful if you cycle it daily.
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.
The one you actually carry. At 17 lb it is light enough for one hand, yet unlike the true pocket units it has the 800W of output needed to run small appliances rather than just charge devices.
Best for: Backpackers, photographers and festival-goers who care about weight above all.
Where it falls short:
- 800W output limits you to electronics and small loads
- 220W solar input means slow off-grid top-ups
A well-priced 1.1kWh with a real 1,800W output and fast charging, a common budget pick for home backup starter kits.
Best for: First-time backup buyers who want 1,800W output cheap.
Where it falls short:
- 37.5 lb for 1.1kWh
- Not expandable
