• Ultra-fast charging, 0-100% in 56 minutes: With a 1500W AC input, it reaches 80% in just 40 minutes and 0-100% in 56 minutes. Solar charging achieves 80% in 1 hour and 100% in 70 minutes. The 800W alternator charges DELTA 3 Plus to 80% in 1 hour and fully in 1.3 hours. Using the EcoFlow Smart Generator, it charges 80% in 40 minutes and 100% in 56 minutes. Hybrid charging (AC + solar) matches this rapid speed.
• Up to 2400W, powers 99% of household appliances: Equipped with multiple interfaces, it can power up to 11 devices simultaneously, making it ideal for emergencies. X-Boost technology enables continuous support for resistive appliances with power needs exceeding 2400W.
• Smart Energy Management System: The app provides 12-hour storm and outage alerts, low battery/storage reminders, and a detailed usage dashboard. Adjust charge speed, set power schedules, and activate power-saving mode. The enhanced Time-of-Use (TOU) mode automatically calculates savings and optimizes charge and discharge times.
• Whisper-Quiet Performance and 10 ms Switch-Over UPS Protection: X-Quiet technology ensures ultra-low noise levels, with just 30 dB below 600W and 40 dB at 1200W, making it perfect for use in a tent or at home without disrupting sleep. The DELTA 3 Plus acts as a true UPS with a 10 ms switch-over time, making it ideal for NAS, servers, POS systems, and critical backups, preventing data loss during unexpected shutdowns.
• Durable and Reliable for 10 Years: Equipped with LiFePO4 (LFP) cells, it offers 4,000 cycles to 80%, providing 25% greater durability than industry standards. The IP65 battery pack ensures triple protection: LFP battery, IP65-rated enclosure, and an advanced Battery Management System (BMS).
• Flexible Expansion up to 5kWh: The DELTA 3 Series integrates effortlessly with EcoFlow’s ecosystem, allowing you to add DELTA 3, DELTA Pro 3, or DELTA 2 Max battery packs. Expand your power capacity to a substantial 5kWh.
