Frequently Asked Questions
Common questions about this comparison
Which is better for home backup power?
EF ECOFLOW DELTA 2 is far better for home backup with its 1024Wh capacity (expandable to 3000Wh) and 1800W AC output, capable of running more powerful appliances. The Anker 535's 512Wh and 500W are more suited for smaller devices.
What's the main difference in AC output power?
The main difference is the power output capability. The EF ECOFLOW DELTA 2 provides a high 1800W AC output, capable of powering most home appliances. In contrast, the Anker 535 offers a 500W AC output, limiting it to less demanding electronics.
Which has a longer battery lifespan?
Both use durable LiFePO4 batteries. However, the EF ECOFLOW DELTA 2 specifies over 3000 cycles to 80% capacity. The Anker 535 also uses LiFePO4, ensuring a long lifespan, but specific cycle count is not provided in the given specs for direct comparison.
Is the EcoFlow Delta 2's expandable capacity a significant advantage?
Yes, significantly. The EcoFlow Delta 2 starts at 1024Wh and can expand up to 3000Wh with additional batteries, offering much greater flexibility for varying power needs. The Anker 535 has a fixed 512Wh capacity.
Which is better for basic outdoor camping?
For basic camping needs powering small devices, the Anker 535 with its 512Wh capacity and 500W output is sufficient and likely more portable. The EcoFlow DELTA 2, while more powerful, is also heavier at 27 lbs and potentially overkill for simple trips.
