EcoFlow Delta Pro 3 vs EcoFlow Delta Pro Portable Power Station

The Delta Pro 3 is the newer, cleaner choice for most people: it runs 240V appliances natively, has a bigger 4,096Wh LFP battery, and takes 2,600W of solar. The original Delta Pro still wins on expandability and cycle life, with a larger ecosystem and more owner reviews behind it. Both are heavy wheeled units, so plan on moving them rarely. Owners of both praise the app and build quality; the Pro 3 draws complaints about its weight and the Pro about its older chemistry and slower solar ceiling.

  • Choose the Delta Pro 3 if you need 240V output for a well pump, dryer or EV charger, want the larger base battery, or plan to charge fast from solar.
  • Choose the Delta Pro if you want the deepest expansion path to 25kWh, a long track record with hundreds of owner reviews, or you already own Delta Pro batteries and the Smart Home Panel.

What reviewers say

EcoFlow Delta Pro 3

  • 4.7 / 5151 ratings

Rated 4.7 out of 5 from 151 ratings. Owners treat it as a serious whole-home backup unit rather than a camping battery. The main complaints are its weight and price.

What people mention
  • WeightCriticisedAt about 114 lbs it is hard to move without help or a cart.
  • OutputPraisedOwners report it runs 240V appliances like central AC and well pumps.
  • PriceCriticisedBuyers call it a premium purchase, and expansion batteries push the cost higher.
  • Charging speedPraisedAC fast charging to 80% in about 50 minutes is a commonly noted strength.

EcoFlow Delta Pro Portable Power Station

  • 4.8 / 5737 ratings

Owners rate it 4.8 out of 5 across 737 ratings and mostly praise its capacity and output for home backup. Complaints center on weight, price and fan noise under load.

What people mention
  • OutputPraisedOwners say it powers fridges, pumps and tools that smaller stations cannot.
  • WeightCriticisedBuyers call it too heavy to carry regularly; it is a set-in-place unit.
  • PriceMixedReviewers see the cost as high but acceptable for the capacity.
  • Fan noiseCriticisedThe cooling fans get loud when drawing high wattage.

Questions and answers

Which is better for running a 240V well pump or dryer?
The Delta Pro 3. It has native 120V and 240V outlets and a 4,000W continuous rating, so it can run many 240V loads directly. The original Delta Pro needs extra hardware for 240V.
Which lasts longer?
The original Delta Pro is rated for 6,500 cycles to 50% capacity; the Pro 3 is rated for 4,000 cycles to 80%. Both use lithium chemistry and should last many years of normal backup use.
Is the Delta Pro 3 worth stepping up to?
Yes if you need 240V, more solar input or a bigger base battery. If you mainly want maximum expandable storage for whole-home backup, the original Delta Pro with the Smart Home Panel is the stronger fit.
Can I charge either one from solar?
Yes. The Pro 3 accepts up to 2,600W across two MPPT ports; the original Pro accepts up to 1,600W. Both work with third-party panels within their voltage ranges.
Which is easier to move around?
The original Delta Pro, at roughly 99 lbs versus about 114 lbs for the Pro 3. Both have wheels, but neither is easy to carry up stairs.
Do both work as a UPS for my home office?
The Pro 3 specifies a 10ms UPS switchover, which is fast enough for most desktop gear. The original Delta Pro also supports backup pass-through, but check the switchover time for sensitive equipment.
