EcoFlow DELTA 2 + DELTA 2 Smart Extra Battery - DELTA2-DELTA2EB
Expandable capacity - 1-3kWh expandable capacity to grow your storage to your needs. Add on the DELTA 2 extra battery to reach 2048Wh, or add on the DELTA Max Extra Battery to hit 3040Wh. Great for home backup or everyday appliances.
Huge AC output - 1800W AC output means you can power more than 90% of your home appliances. Or, try plugging in up to 15 devices at once. Unlike other brands, DELTA 2 can prevent overloading from devices up to 2200W thanks to X-Boost technology.
7x Faster AC charging - 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.
Or go green without sacrificing speed - Plug in portable solar panels and get up to 500W input to charge from anywhere in as fast as 3 hours.
Built to last 6x longer - Get 10 years of daily use until hitting 80% of its original capacity. That’s down to its LFP battery chemistry giving you 3000+ cycles.
Control from anywhere - Use the EcoFlow app to control your DELTA 2 from anywhere using Wi-Fi. Link with Bluetooth when off-grid. Either way, you can check charging data, customize settings and adjust the charging speed with ease.
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 power station has the potential to be re-charged 3,000 times over its lifetime.
Huge AC Output
How 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. Delta 2 detects the voltage and current in real-time thanks to its MPPT (Maximum Power Point Tracking) in order to reach >98% efficiency.
