Goal Zero Yeti 700 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
Goal Zero Yeti 700 costs $200 less. Whether that gap is worth closing depends on what you need to run.
- Ampace Andes 1500 holds 116% more energy (1462Wh vs 677Wh), so it runs the same load proportionally longer.
- Ampace Andes 1500 has 2600W more surge headroom (3600W vs 1000W) — that decides whether a fridge, pump or AC compressor will actually start.
- Goal Zero Yeti 700 is 16.5 lb lighter (20.3 lb vs 36.8 lb).
- Goal Zero Yeti 700 is rated for 4,000 cycles vs 3,000 — meaningful if you cycle it daily.
Goal Zero Yeti 700
The largest of the rugged compacts. Still not an appliance unit — 600W of output caps what it can drive — but a durable mid-size companion.
Best for: Rugged off-grid use where durability outranks running heavy loads.
Where it falls short:
- 600W output rules out compressors and heaters
- 20.3 lb is heavy for 677Wh
Ampace Andes 1500
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
