Same performance, more compact. With the EcoFlow Delta 3 additional battery (1 kWh) you can achieve a capacity of 2 kWh. It is therefore a third smaller and lighter than the Delta 2 power station. Durable and robust for reliable data backup anywhere and at any time. Triple all-round protection for guaranteed safety. The third generation LiFePO4 cells (LFP) enable fast charging without compromising on durability. With 4,000 charge cycles up to 80% capacity, you can work reliably for up to 10 years - 25% longer than the industry standard.
