When you’re shopping for a high-capacity portable power solution, EcoFlow’s Delta Pro and Delta Pro Ultra are two contenders that deserve your attention. Both are designed to offer reliable power for home backup, outdoor adventures, or professional use, but what sets them apart? In this detailed comparison, we’ll dive into the technical aspects of both products, their capabilities, and suitability for different use cases, helping you make an informed decision.
Design and Portability
Beginning with their physical characteristics, the Delta Pro boasts a hefty structure, weighing in at 99 pounds, while the Pro Ultra’s separate inverter and battery modules come at 70 and 116.4 pounds respectively. Their sizes are respectable considering the technology packed inside, and while neither can be called lightweight, they are portable in the sense that they can be relocated as needed with some effort.
Power and Capacity
Power capacity is where these products truly shine. The Delta Pro kicks off with a 3600Wh capacity, expandable to an impressive 25kWh with additional batteries. The Pro Ultra starts at 6kWh and scales up to a massive 90kWh – enough to power your home for a month. Both systems offer more than just backup power; they’re capable of being part of a broader energy management strategy.
Expansion and Compatibility
Expansion is made easy with both models supporting additional batteries for increased capacity. The Delta Pro works with the Delta Pro Smart Extra Battery, and the Pro Ultra is expandable via stacking multiple units. They’re both compatible with solar panel inputs for improved sustainability, though the Pro Ultra takes a lead with its higher solar input range and integration flexibility.
Charging and Energy Input
Charging methods are diverse for both units. The Delta Pro can charge from AC, solar, or even EV charging stations, with a 2.7 hour charge time from AC. The Pro Ultra, however, towers with its versatile charging options and compatibility with current solar installations, as well as offering a rapid solar energy collection and higher solar input capabilities.
