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
Bluetti EB3A costs $760 less. Whether that gap is worth closing depends on what you need to run.
- Ampace Andes 1500 holds 446% more energy (1462Wh vs 268Wh), so it runs the same load proportionally longer.
- Ampace Andes 1500 has 2400W more surge headroom (3600W vs 1200W) — that decides whether a fridge, pump or AC compressor will actually start.
- Bluetti EB3A is 26.7 lb lighter (10.1 lb vs 36.8 lb).
- Ampace Andes 1500 is rated for 3,000 cycles vs 2,500 — meaningful if you cycle it daily.
Bluetti EB3A
The budget veteran. 268Wh at $239 with a 30-minute recharge — still one of the fastest-charging small units you can buy.
Best for: Budget campers who value fast top-ups between trips.
Where it falls short:
- 2500 cycles is the lowest here
- 268Wh empties fast under real load
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
