Bluetti EB3A vs Anker SOLIX C300
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
Anker SOLIX C300 costs $60 less. Whether that gap is worth closing depends on what you need to run.
- Anker SOLIX C300 holds 7% more energy (288Wh vs 268Wh), so it runs the same load proportionally longer.
- Bluetti EB3A has 600W more surge headroom (1200W vs 600W) — that decides whether a fridge, pump or AC compressor will actually start.
- Anker SOLIX C300 is 1.5 lb lighter (8.6 lb vs 10.1 lb).
- Anker SOLIX C300 is rated for 3,000 cycles vs 2,500 — meaningful if you cycle it daily.
Neither of these will start a sump pump or well pump — both surge below the ~3,400W those motors need. If home backup with pumps is your use case, look at higher-surge models instead of either of these.
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
Anker's smallest. 288Wh at $179 with three USB-C ports — aimed squarely at people charging modern devices, not running appliances.
Best for: Content creators and travelers with a bag full of USB-C gear.
Where it falls short:
- 300W output is device-only territory
- 100W solar input
