Category Scores
Capacity
The EcoFlow DELTA Pro 3 leads clearly here, 9.5 against 6.5 — a 3.0-point margin on usable watt-hours and how long it runs real appliances. If that is what you are buying for, the EcoFlow DELTA 3 Plus does not close the gap elsewhere.
Output Power
The EcoFlow DELTA Pro 3 leads clearly here, 9.8 against 8.0 — a 1.8-point margin on continuous AC output and whether the surge rating is genuine. If that is what you are buying for, the EcoFlow DELTA 3 Plus does not close the gap elsewhere.
Recharge Speed
The EcoFlow DELTA Pro 3 and EcoFlow DELTA 3 Plus are level here, at 9.0/10 each. how quickly it refills from mains power is not what separates these two — look to the categories where the scores diverge.
Solar Input
The EcoFlow DELTA Pro 3 is marginally ahead, 9.8 to 9.5. A gap this small rarely decides a purchase on its own, though it counts if maximum solar input and how practical off-grid recharging is is your priority.
Portability
The EcoFlow DELTA 3 Plus leads clearly here, 6.5 against 2.5 — a 4.0-point margin on weight and handling relative to capacity. If that is what you are buying for, the EcoFlow DELTA Pro 3 does not close the gap elsewhere.
Expandability
The EcoFlow DELTA Pro 3 leads clearly here, 9.8 against 8.5 — a 1.3-point margin on whether extra battery packs can be added, and how far it scales. If that is what you are buying for, the EcoFlow DELTA 3 Plus does not close the gap elsewhere.
Features
The EcoFlow DELTA Pro 3 leads clearly here, 9.5 against 9.0 — a 0.5-point margin on UPS switchover, app control, port variety and extras. If that is what you are buying for, the EcoFlow DELTA 3 Plus does not close the gap elsewhere.
Value
The EcoFlow DELTA Pro 3 and EcoFlow DELTA 3 Plus are level here, at 8.0/10 each. capacity and output relative to price is not what separates these two — look to the categories where the scores diverge.
