When it comes to portable power, the market has no shortage of options. But how do you decide which power station is the right fit for your needs? In this article, we will dive deep into two of the popular choices available: the Bluetti AC70 and the EcoFlow Delta mini. We’ll compare their specifications, features, and optimal use cases to help you make a well-informed decision.
Power Capacity and Battery Life
Central to any portable power station is its capacity and battery longevity. Bluetti’s AC70 boasts a 768Wh capacity with a lithium iron phosphate (LiFePO₄) battery, known for its durability, offering over 3,000 charge cycles before dipping to 80% of its original capacity. The EcoFlow Delta mini, on the other hand, features a slightly higher capacity of 882Wh, using NCM Li-ion battery technology, and guarantees about 800 cycles to the same state of health.
Charging and Recharging
The availability and variety of charging options are essential for optimal flexibility. Both the AC70 and Delta mini provide AC, solar, and car charging capabilities. Highlight-worthy is the AC70’s impressive 950W maximum AC input allowing a rapid charge of just 1.3-1.6 hours, while the Delta mini is no slouch with the efficient X-Stream technology ensuring a full recharge within approximately 1.6 hours. Solar charging paces differ slightly, with the AC70 taking between 2.8-3.3 hours via a 500W panel and the Delta mini recharging in 3-6 hours with a 300W panel.
Output Ports and Power
When you’re looking to power various devices, the number and type of output ports can swing your decision. The AC70 services your devices with dual AC outlets at 1000W total, two 100W USB-C ports, and more. Meanwhile, the Delta mini punches above its weight with five AC outlets boasting a higher combined output of 1400W. It also includes USB-A and USB-C ports.

Design and Portability
In the world of portable power stations, the size and weight make a big difference. The AC70 weighs around 22.5 pounds and has a fairly compact shape. The Delta mini is slightly heavier at 23.6 pounds but maintains a design that’s still easy to carry and stow away in your car or home.
Advanced Features and Capabilities
Both models offer innovative technologies and smart features. The AC70 shines with a UPS function and mobile app compatibility, allowing seamless power switching and remote control. The Delta mini also interacts with an app for real-time power management and is supported by the stunning X-Stream charging technology.
Conclusion
While both the Bluetti AC70 and EcoFlow Delta mini are strong contenders in the portable power space, your choice may come down to specific needs. Whether it’s the higher output capability and number of outlets of the Delta mini or the superior battery life and rapid charging of the AC70, each has its unique advantages. Consider your power needs, the devices you wish to support, and where you’ll be using your power station most to make the best choice.
