When it comes to portable power solutions, there’s an abundance of options on the market. But two models that frequently catch the eyes of enthusiasts and casual users alike are the EcoFlow River and the Bluetti AC2A. Picking the right one can be a bit daunting, which is why we’re diving deep into a technical comparison of these two powerhouses to help you decide.
Capacity and Battery Life
| EcoFlow River | Bluetti AC2A | |
|---|---|---|
| Capacity | 288Wh | 204.8Wh |
| Battery Chemistry | NCM Lithium-ion | Lithium Iron Phosphate (LiFePO4) |
| Lifecycle | 500+ cycles to 80% capacity | 3,000+ cycles to 80% capacity |
| Cycle Life Advantage | Bluetti AC2A | Bluetti AC2A |
The EcoFlow River boasts a 288Wh capacity powered by NCM Lithium-ion battery, which is decent for several electronic devices. However, the Bluetti AC2A comes with a Lithium Iron Phosphate battery, which is known for longer lifecycles, hitting over 3000 cycles to 80% capacity versus 500 cycles from the River.
Output and Efficiency
| EcoFlow River | Bluetti AC2A | |
|---|---|---|
| Continuous Output | 600W | 300W |
| Surge Output | 1200W | 600W |
| AC Outlets | 3 | 2 |
| USB-C Output | 1 (PD) | 1 (100W Max) |
| Car Outlet | 1 | 1 |
| Total Output Ports | 8 | 6 |
EcoFlow River takes the lead in terms of output, providing 600W of continuous power and a max surge output of 1200W. That extra juice means it can handle more energy-intensive devices with ease. Bluetti AC2A offers a more modest 300W continuous output but compensates with a 100W max USB-C port, ideal for fast-charging laptops and other compatible devices.
Charging and Portability
| EcoFlow River | Bluetti AC2A | |
|---|---|---|
| X-Stream Fast Charging | Yes | No |
| Solar Charging | 200W Max | 200W Max |
| Car Charging | Yes | Yes |
| Wall Outlet Charging | Yes | Yes |
| Weight | 11 lbs | 7.9 lbs |
| Dimensions | 11.3 x 7.3 x 7.7 in | 9.8 x 6.1 x 6.8 in |
EcoFlow excels with its X-Stream fast charging, juicing up from 0 to 80% in less than an hour. Both models support solar and car charging, but the River charges slightly faster via solar. The Bluetti AC2A, though, is more compact and lighter, making it the better choice for long treks where space and weight really matter.
Additional Features and Considerations
EcoFlow River and Bluetti AC2A both have expandable capabilities with compatible solar panels and have built-in management systems for safety. They also offer remote monitoring via dedicated apps. Bluetti, however, provides a notably longer warranty period of 5 years compared to EcoFlow’s 2 years.
