Which is better for whole-home backup?

Both can scale to whole-home backup, but the Anker F3800 Plus offers higher single-unit output (6,000 W) and slightly more expansion capacity (53.8 kWh). The Delta Pro 3 provides faster charging and a lower entry price.

Both use LiFePO4 batteries. Anker rates the F3800 Plus at 3,000+ cycles to 80% capacity. EcoFlow does not specify cycle life for the Delta Pro 3, but LiFePO4 typically lasts 3,000–5,000 cycles.

Is the Anker worth the extra cost?

Only if you need the higher 6,000 W output or the extra solar input. For most users, the Delta Pro 3 at $845.10 is a much better value.

Can I use these for RVing?

Yes, both support 120V/240V output. The Anker F3800 Plus includes TT-30R and L14-30R ports specifically for RV use. The Delta Pro 3 requires adapters for some RV connections.

Which has faster charging?

The Delta Pro 3 charges from 0 to 80% in about 50 minutes via AC. Anker does not specify a charge time for the F3800 Plus, but it supports fast charging.
