Tesla Battery's technology
Say goodbye to technology that's made to die in a couple of months. Delta 2's LiFePO4 battery chemistry gives you years of regular use until hitting 80% of its original capacity.
At the heart of the new EcoFlow DELTA 2 is the LFP battery; this is the same type they use in Tesla vehicles and boasts a lifetime six times greater than the industry average at 500 cycles. As a result, this has the potential to be re-charged 3,000 times over its lifetime.
Expandable capacity for your needs
It's original 1kWh capacity provides you with enough energy for your essentials for hours. Need more? Link it to the Delta 2 Extra Battery to reach 2048kWh, or couple it with a Delta Max Extra Battery to hit 3040kWh. Best home backup for your loved ones.
Huge AC OutputHow peaceful is it to know that you can keep your largest and most appliances running, even when a blackout its? More than 90% of your home appliances can be powered with its huge 1800W output. You can plug up to 15 devices at once, thanks to X-Boost Technology that will prevent overloading.
The fastest charging on the market
X-Stream tech means that Delta 2 charges 7 times faster than the competition. That's 0-80% in just 50 minutes and 0-100% in 80 minutes with AC Input. If you'd rather go green without sacrificing performance, you can pair your Delta 2 with solar panels and charge in as fast as 3-6 hours with 1x400W, or 2x220W portable solar panels.
