Goal Zero Yeti 1000X vs Ampace Andes 1500
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
Ampace Andes 1500 costs $200 less. Whether that gap is worth closing depends on what you need to run.
- Ampace Andes 1500 holds 49% more energy (1462Wh vs 983Wh), so it runs the same load proportionally longer.
- Ampace Andes 1500 has 600W more surge headroom (3600W vs 3000W) — that decides whether a fridge, pump or AC compressor will actually start.
- Goal Zero Yeti 1000X is 5.1 lb lighter (31.68 lb vs 36.8 lb).
- Ampace Andes 1500 uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- Ampace Andes 1500 is rated for 3,000 cycles vs 500 — meaningful if you cycle it daily.
We'd skip the Goal Zero Yeti 1000X in this matchup. It costs $200 more than the Ampace Andes 1500 while matching or trailing it on capacity, surge and cycle life — there's no spec here that justifies the premium.
The older X-series 1kWh. Rugged and expandable, but its Li-ion cells and 2-year warranty look dated next to the LiFePO4 6th-gen Yeti 1000.
Best for: Only at a discount against the newer LiFePO4 Yeti 1000.
Where it falls short:
- NMC — ~500 cycles vs 4,000 for the new Yeti 1000
- 2-year warranty
Backed by an Amperex/CATL cell pedigree, the Andes 1500 stands out on charge speed — 0-80% in well under an hour — and a light 36.8 lb for 1.5kWh.
Best for: Buyers who prize fast charging and low weight at 1.5kWh.
Where it falls short:
- Newer brand with a thinner track record
- Not expandable
