Buy on AmazonOur verdict
Top of the category versus the value entry: nearly double the capacity, 50% more output, and vastly more expansion for roughly $500 more. If battery backup is your primary outage strategy, the DELTA Pro's headroom is worth it. If it's a supplement — quiet overnight power beside a fuel generator — the Anker covers that for less.
Pick the EcoFlow if…
- ✓Battery is the primary backup plan
- ✓3,600W output / 3.6kWh+ capacity needs
- ✓Solar charging at scale (1,600W input)
Pick the Anker if…
- ✓Supplemental silent power, not primary
- ✓Best entry price from a trusted brand
- ✓Grab-and-go size preferred
