EcoFlow RIVER 2 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 July 29, 2026

The short answer

EcoFlow RIVER 2 costs $500 less. Whether that gap is worth closing depends on what you need to run.

Allpowers R1500 holds 350% more energy (1152Wh vs 256Wh), so it runs the same load proportionally longer.
Allpowers R1500 has 2400W more surge headroom (3000W vs 600W) — that decides whether a fridge, pump or AC compressor will actually start.
EcoFlow RIVER 2 is 29.8 lb lighter (7.7 lb vs 37.5 lb).
Allpowers R1500 is rated for 3,500 cycles vs 3,000 — meaningful if you cycle it daily.

⚠️ 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.

EcoFlow RIVER 2

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

Allpowers R1500

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
