Goal Zero Yeti 1500X 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
Allpowers R1500 costs $1300 less. Whether that gap is worth closing depends on what you need to run.
- Goal Zero Yeti 1500X holds 32% more energy (1516Wh vs 1152Wh), so it runs the same load proportionally longer.
- Goal Zero Yeti 1500X has 500W more surge headroom (3500W vs 3000W) — that decides whether a fridge, pump or AC compressor will actually start.
- Allpowers R1500 is 8.1 lb lighter (37.5 lb vs 45.64 lb).
- Allpowers R1500 uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- Allpowers R1500 is rated for 3,500 cycles vs 500 — meaningful if you cycle it daily.
The Goal Zero Yeti 1500X is poor value on paper: 0.76 Wh per dollar versus 1.65 for the Allpowers R1500. Only worth it if you specifically need its higher output or 240V capability — otherwise you're paying a large premium per watt-hour.
The previous-generation flagship. Its NMC battery is the catch — far fewer cycles than the LiFePO4 units now around it, including its own replacement.
Best for: Only at a steep discount against the newer LiFePO4 Yeti 1500.
Where it falls short:
- NMC chemistry — roughly 500 cycles vs 4,000 for the new 1500
- 180-minute recharge is slow
- Only a 2-year warranty
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
