Goal Zero Yeti 6000X 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 $4500 less. Whether that gap is worth closing depends on what you need to run.
- Goal Zero Yeti 6000X holds 315% more energy (6071Wh vs 1462Wh), so it runs the same load proportionally longer.
- Ampace Andes 1500 has 100W more surge headroom (3600W vs 3500W) — that decides whether a fridge, pump or AC compressor will actually start.
- Ampace Andes 1500 is 69.2 lb lighter (36.8 lb vs 106 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.
If you plan to cycle the battery daily, think twice about the Goal Zero Yeti 6000X. Its NMC cells are rated for 500 cycles against the LiFePO4 rival's longer life — over years of regular use that's the more expensive unit, whatever the sticker says.
A huge-capacity home unit whose weakness is the same as its siblings: NMC cells with a low cycle count, at a flagship price.
Best for: Large-capacity backup for infrequent, deep-discharge use.
Where it falls short:
- NMC — ~500 cycles
- 2,000W output is low for the capacity
- 106 lb, 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
