Quick answer
The EcoFlow Delta Pro 3 is EcoFlow’s current flagship power station: a 4,096Wh LiFePO4 battery with 4,000W continuous AC output (8,000W via X-Boost surge) that recharges from 0-80% in about 50 minutes on wall power, according to EcoFlow’s own published specs. It carries a $3,699 MSRP, but EcoFlow’s own site and Amazon both commonly list it between $1,999 and $2,699 depending on active promotions — budget for that range, not the sticker price. It’s the newer, larger unit EcoFlow now positions above the original Delta Pro, which remains on sale as a cheaper way into the same general capacity class.
We flagged the Delta Pro 3 as a distinct model in our Delta Pro review after readers kept searching for it under the same “Delta Pro” name. This review covers the Pro 3 on its own: what the extra capacity and faster charging actually buy you, and how it stacks up against the Anker SOLIX F3800 in the same whole-home-backup tier.

What we like
- Recharge speed is the real upgrade over the original Delta Pro. EcoFlow’s own specs put 0-80% wall recharge at about 50 minutes, roughly twice as fast as the original Delta Pro’s 1.7-hour figure — meaningful if you’re topping up between outages or camping trips rather than leaving it plugged in full-time.
- 8,000W of surge headroom. X-Boost surge on a single unit reaches 8,000W, enough to start compressor-driven loads like a well pump or central AC’s startup draw that trip smaller stations’ surge limits.
- Expansion is straightforward math. Two Smart Extra Batteries take one unit to 12kWh without needing a second full base unit, and EcoFlow rates up to 3 units in parallel for buyers who eventually want a genuine whole-home system.
- Street pricing lands in the same neighborhood as the Anker SOLIX F3800, without needing as deep a sale. The Delta Pro 3’s common $1,999-2,699 range overlaps the Anker SOLIX F3800’s $1,600-2,400 range, but the Delta Pro 3 reaches its lower prices on EcoFlow’s own site and regular Amazon listings more often, rather than requiring one of the F3800’s occasional deep sale windows.
Where it falls short
- At 113.5 lb, this isn’t a grab-and-go unit. It’s built for a garage, basement, or RV bay that stays put, not a rotation between a truck bed and a campsite.
- 4,000 cycles to 80% sounds lower than the original Delta Pro’s 6,500-plus, but the numbers aren’t directly comparable. EcoFlow rates the Delta Pro 3 to 80% depth of discharge and the original Delta Pro to 50% depth — a shallower depth naturally supports more cycles, so don’t read the original’s figure as simply “better” without accounting for the different benchmark.
- Whole-home automatic switchover needs EcoFlow’s Smart Home Panel 2, sold separately. Without it, you’re manually plugging in circuits during an outage rather than getting automatic transfer.
- $3,699 MSRP is rarely the real price, which makes comparison shopping harder. EcoFlow’s own site discounts it often enough that treating the sticker price as a baseline will make every competitor look artificially cheaper by comparison.
Who should buy it
The Delta Pro 3 makes sense for buyers who want EcoFlow’s current flagship — faster charging and more surge headroom than the original Delta Pro, at a similar or lower street price once a sale hits. If portability matters more than whole-home capacity, a 1-2kWh unit like the EcoFlow Delta 2 covers most outage and camping scenarios at a fraction of the weight and cost. For true 240V split-phase support to run hardwired appliances directly, compare it against the Anker SOLIX F3800 before buying. Our best power station for home backup picks line the Delta Pro 3 up against both directly.

The bottom line
The EcoFlow Delta Pro 3 is the flagship to consider once a 1-2kWh station isn’t enough and you want EcoFlow’s newest hardware rather than the original Delta Pro — faster recharging, more surge capacity, and a cleaner path to 12kWh on a single unit. It’s heavy, and the $3,699 MSRP overstates what most buyers actually pay, but caught at its common $1,999-2,699 street price it’s a genuine alternative to the Anker SOLIX F3800 for whole-home-leaning backup.
