EcoFlow DELTA 3 Ultra Portable Power Station vs EcoFlow Delta Pro 3

Both are EcoFlow LFP stations with 10ms UPS switching, so the choice comes down to capacity and output versus size and weight. The Delta Pro 3 is the stronger whole-home unit: 4,096Wh, 4,000W output with 120V and 240V, and expansion to 48kWh. The Delta 3 Ultra is smaller and lighter at 3,072Wh and 3,600W, with app-controlled output priority and a faster wall charge to 80%. Owners rate both 4.7 out of 5; the Pro 3 has far more ratings behind it.

  • Choose the Delta 3 Ultra if you want a lighter, more compact 3kWh station for circuits you pick in the app, and 240V whole-home output is not a requirement.
  • Choose the Delta Pro 3 if you need 240V for central air, well pumps or a transfer switch, or plan to grow past 4kWh toward whole-home backup.

What reviewers say

EcoFlow DELTA 3 Ultra Portable Power Station

  • 4.7 / 559 ratings

Owners rate it highly, praising the fast wall charging, the steady output under heavy loads and the quiet operation. Complaints center on weight and on the cost of expanding capacity.

What people mention

  • Output powerPraisedReviewers report it runs large appliances and tools without tripping.
  • WeightCriticisedBuyers note it is very heavy and best left in one place.
  • NoisePraisedUsers describe it as quiet in normal operation.

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.

Questions and answers

Which is better for running central air conditioning?
The Delta Pro 3. It delivers 4,000W at 120V and 240V, which the Delta 3 Ultra cannot do at all. The Ultra's 3,600W output suits fridges, tools and electronics, not a 3-ton AC.
Which one lasts longer?
Both use automotive-grade LFP cells rated for roughly 10 years of regular use, so cycle life is close. The Pro 3 adds an IP65-rated battery pack, which helps in dusty or damp storage.
Is the Delta Pro 3 worth stepping up to?
Yes if you need 240V, more than 3kWh of daily runtime, or a path to whole-home backup. If you only back up a few circuits, the Delta 3 Ultra covers it in a lighter box.
Which charges faster from the wall?
The Delta Pro 3 reaches 80% in about 50 minutes. The Delta 3 Ultra takes about 1.48 hours to 80% on AC, though pairing solar with a generator cuts that to about 48 minutes.
Can I expand either one later?
Yes. The Delta 3 Ultra grows to about 11kWh with extra batteries and a Smart Generator. The Delta Pro 3 grows to 48kWh and can run parallel units for 12,000W total.
Which is easier to move around?
The Delta 3 Ultra. The Delta Pro 3 weighs 114.6 lbs, so it is best left in one spot or moved with a cart. The Ultra is the one to carry between rooms or load into a vehicle.
