Our take
The EcoFlow DELTA Pro is a battery-based 'solar generator' rather than a gas unit, packing a 3,600Wh LiFePO4 (LFP) battery and a 3,600W AC output that can surge to 4,500W with X-Boost. Because it produces zero fumes and runs silently, it can be used indoors, in apartments, and during camping or RV trips where a gas generator simply isn't an option. It recharges fully in about 2.7 hours from a wall outlet, accepts solar input, and is expandable with extra batteries and smart panels for larger backup needs. The tradeoff versus gas generators is finite runtime per charge and a higher up-front cost, but for clean, quiet, maintenance-free backup the DELTA Pro is a category leader and frequently discounted on Amazon.
What we like
- Completely silent and fume-free, safe for indoor and apartment use
- Large 3,600Wh LiFePO4 battery with long cycle life and 3,600W output (4,500W X-Boost)
- Fast 2.7-hour wall charging plus solar input and expandable battery capacity
- No fuel, oil, or maintenance, and frequently discounted on Amazon
What to keep in mind
- Finite runtime per charge unless paired with solar or extra batteries
- High up-front cost compared to gas generators of similar peak wattage
- Heavy at about 99 lbs despite being marketed as portable
