|---|---|---|
| AC Outlets | 2 x 300W Total | 6 x 1800W Total |
| USB-C Port | 1 x 100W Max | 2 x 100W Max each |
| USB-A Ports | 2 x 12W | 2 x 12W, 2 x fast charge 18W |
| 12V DC Outlet | 1 x 12V/10A | 1 x 12.6V, 10A, 126W Max |
| Surge Power | 600W | 2700W |
Additional Features and Safety
The AC2A and Delta 2 are equipped with features that complement their primary functions. From built-in BMS for safety to MPPT technology for efficient solar charging, these devices are engineered for convenience and reliability. Bluetti presents an intuitive mobile app for remote monitoring, while EcoFlow goes a step further with expandable ecosystems, offering compatibility with other products such as portable air conditioners.
| Feature | Bluetti AC2A | EcoFlow Delta 2 |
|---|---|---|
| Mobile App | Yes | N/A |
| BMS | Yes | Yes |
| MPPT Technology | Yes | Yes (>98% efficiency) |
| Expandable Ecosystem | No | Yes |
| Safety Protections | Multiple | Multiple |
Pricing Considerations
Finding the right power station also depends on your budget. The Bluetti AC2A, with a smaller capacity and fewer features, typically comes with a smaller price tag than the EcoFlow Delta 2, which offers more power and expandability. When considering cost, evaluate the value based on your power needs, the frequency of use, and the potential need for accessories or expansion.
Final Thoughts
The Bluetti AC2A and EcoFlow Delta 2 both serve as excellent mobile power solutions, but selecting the right one is a personal choice that hinges on your specific needs. If compactness, lightweight design, and affordability are your top priorities, the AC2A might be the ideal choice. However, if you require higher power output, expandable battery capacity, and rapid charging, the Delta 2 is likely the better fit. Consider your power consumption, expansion needs, and budget to guide your choice between these two impressive portable power stations.
