EcoFlow DELTA Pro 3
The DELTA Pro 3 is four kilowatt-hours and a 240-volt outlet one owner wired into the breaker box instead of fifteen extension cords. It wins 20 of 34 head-to-heads and has never beaten a Jackery in five tries, a streak Jackery keeps framed. Owners run above the norm; eight serious reports: shutdowns, support asking for 112 pounds shipped back.

What the DELTA Pro 3 actually runs
The load profiles every comparison on the site is scored on, computed for this unit alone: energy needed against the usable tank after inverter losses, and whether the inverter holds and starts the biggest single load.

03 · From the verdicts
Who it is for, and when a rival won instead
Each line is lifted from a written matchup where it decided the verdict, and links to the page it came from. Repeated across many matchups means it is the unit’s signature, not one author’s opinion.
Buy the DELTA Pro 3 if…
You want the option to relocate the unit, or you're carrying it yourself without help.
Decided 14 matchups · read one →
You already own EcoFlow gear and want everything in one app and one expansion chain climbing toward 48kWh [A1].
Decided 3 matchups · read one →
You want one box, not two — a single 112.4 lb unit instead of a stacked 148.8 lb system.
Decided 3 matchups · read one →
You need to charge and run a load at the same time — the F3800 has no pass-through mode [B4].
Decided 3 matchups · read one →
A rival won when…
You want the lower lifetime cost per kWh and don't specifically need 240V output.
Decided 18 matchups · read one →
Your daily draw is genuinely close to 4,685Wh — the one scenario where the DELTA Pro 3's smaller tank simply can't keep up.
Decided 3 matchups · read one →
You need to start big motor loads — 5,000W continuous and a 10,000W surge at a 2.0× ratio clear what the DP3's 6,000W might trip on.

You'd rather put the other $1,849 into panels, a second unit, or the trip itself.

How to read this
- Usual is the price the unit carried most of the time, tested for how long it held rather than how often we looked. A weekend promotion cannot move it.
- Best is the lowest price we have read on the store itself. Typed coupon codes, member-only prices and marketplace listings are not counted; anything applied automatically at checkout is.
- A gap in the line is a day we could not read a price. We never draw across one, and we never show the store’s own “was” price.

56% positive weighted · corpus 51% · above the norm
Raw counts reward whoever writes most, and people write when something breaks. Here each report is weighted by what the complaint costs a buyer (a failure outranks an app gripe) and by its evidence (a measured owner report outranks a shopper’s opinion), then compared with every report in the corpus.

Questions people ask
Which is cheaper, the EcoFlow DELTA 3 Max or the DELTA Pro 3?
The DELTA 3 Max, by $1,550 — $849 against the DELTA Pro 3's $2,399. It's also the cheaper unit to own long-term, at $0.10 per lifetime kWh against the Pro 3's $0.15.
Is the DELTA Pro 3 worth 61.7 lbs more?
Only if you need the capacity it buys. At 112.4 lbs against the DELTA 3 Max's 50.7, it's more than double the weight for headroom that matters on a full weekend trip or an extended blackout. For a CPAP, a remote workday, or a tailgate — jobs the DELTA 3 Max clears using half its tank or less — you'd be carrying 61.7 extra lbs for margin you won't use.
Is the Anker SOLIX F3800 Plus worth the extra money over the EcoFlow DELTA Pro 3?
Only if you can name the appliance that needs it. The $101 premium buys 2,000W more continuous output, 3,000W more surge and 1,200W more solar input, and across all six load profiles we model, both units already power the peak. If you're backing up a fridge, some lights and electronics, you're paying for ceilings you won't reach and carrying 19.9 extra pounds to own them.
Is the EcoFlow DELTA Pro 3 worth $1,450 more than the DELTA 2 Max?
If your use is real camping weekends, blackouts, or tailgate days, yes — it wins every one of those scenarios, and in one case (Weekend Camping) the DELTA 2 Max literally can't finish the trip at 121% of its capacity. If your heaviest load is an overnight CPAP, no: both handle that at under a fifth of capacity, so save the $1,450.
How much heavier is the DELTA Pro 3 than the DELTA 2 Max?
61.7 lbs heavier — 112.4 lbs against 50.7 lbs (112.4 minus 50.7). That's the difference between a one-person lift and a genuine two-person or cart job.
