Anker SOLIX C300 vs Bluetti AC2A
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 $20 less. Whether that gap is worth closing depends on what you need to run.
- Anker SOLIX C300 holds 41% more energy (288Wh vs 204Wh), so it runs the same load proportionally longer.
- Bluetti AC2A is 0.7 lb lighter (7.9 lb vs 8.6 lb).
We'd skip the Bluetti AC2A in this matchup. It costs $20 more than the Anker SOLIX C300 while matching or trailing it on capacity, surge and cycle life — there's no spec here that justifies the premium.
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
One of the cheapest LiFePO4 stations on the market. 204Wh is tiny, but a 200W solar input that outpaces the capacity makes it a surprisingly capable little off-grid trickle unit.
Best for: Ultralight campers who recharge from a panel daily.
Where it falls short:
- 204Wh is genuinely small
- 300W output is device-only
