Power & Performance
Both models provide 300W of continuous AC power, which is plenty for phones, laptops, lights, and small appliances. Surge capacity tops at 600W, enough for short bursts when starting devices like fans or mini-fridges.
Performance-wise, they’re evenly matched in output, but EcoFlow River 2 benefits from EcoFlow’s advanced X-Boost mode, which can power resistive loads up to 600W with reduced voltage — handy for borderline appliances.
Battery Capacity & Cycle Life
Here’s where capacity counts:
- EcoFlow River 2: 256Wh
- Bluetti AC2A: 204.8Wh
This gives the River 2 roughly 25% more usable energy per cycle, which could mean an extra phone charge or extended LED light runtime. Both use long-lasting LiFePO4 batteries rated for 3000+ cycles to 80% capacity, ensuring years of use.
Output Ports & Expandability

BLUETTI AC2A Portable Power Station
from: BLUETTI US
Port layout is nearly identical:
- 2 × AC Outlets (300W)
- 1 × 12V Car Port
- 2 × USB-A
- 1 × USB-C (Fast Charging)
Bluetti AC2A edges ahead slightly in USB-C output (100W vs River 2’s 60W), ideal for fast-charging newer laptops or tablets. However, neither model supports battery expansion — these are designed for grab-and-go power, not modular setups.
Portability & Weight
Portability is a tie — both weigh under 8 lbs and have built-in handles for easy carry. Perfect for camping, light overlanding, or power outages where mobility matters.
- EcoFlow River 2: 7.7 lbs
- Bluetti AC2A: 7.9 lbs
The small difference is negligible for real-world use.
Charging Options
Charging speed is a major win for EcoFlow River 2, reaching 0–100% in just 60 minutes via AC thanks to its ultra-fast charger. The Bluetti AC2A is close at 70 minutes, but not quite as quick.
Solar input:
- River 2: Max 110W
- AC2A: Max 200W
So if you’re relying heavily on solar panels, Bluetti AC2A offers faster off-grid charging — assuming your panels can provide the input.
Price & Value
- EcoFlow River 2 MSRP: ~$239
- Bluetti AC2A MSRP: ~$179
If budget is tight, Bluetti AC2A is one of the most affordable LiFePO4 power stations on the market. However, the River 2 brings faster charging and more capacity, justifying the higher price for some users.
Look for deals — both units often go on sale. [Link to: Best Portable Power Stations]
Final Verdict
Choose EcoFlow River 2 if:
- You want faster charging (1 hour full charge)
- You need more capacity (256Wh)
- You like app control and EcoFlow’s ecosystem
Choose Bluetti AC2A if:
- Budget is your top concern
- You want the highest solar input for its size
- You need 100W USB-C charging for a laptop
For pure value under $200, the Bluetti AC2A is tough to beat. But if you can stretch your budget, the EcoFlow River 2 offers a faster, slightly more robust experience.
