EcoFlow DELTA 2 + DELTA Max Smart Extra Battery

 

  • 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.
  • 5-year warranty Unlock an extended 5-year warranty for worry-free experience.


EcoFlow DELTA 2 is a must-have for any home that puts power security & comfort first. Ensure you're prepared with the power station made for almost any situation your family could find themselves in. All while staying green.

 

Make it a triple. Expand capacity.

With a capacity of 1kWh to start with, you’ve got enough energy for your essentials for hours on end. Need even more? 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.

 

 

Power pretty much anything.

A 1800W AC output means you can power more than 90% of your home appliances. That’s your microwave, fridge, or even coffee maker covered in a blackout. Or, try plugging in up to 15 devices at once for when you’re around the table with the family. Unlike other brands, DELTA 2 can prevent overloading from devices up to 2200W thanks to X-Boost technology.


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 with AC input, or 0-100% in 80 minutes.



Go green without sacrificing speed.

Pair with solar panels and charge in as fast as 3-6 hours with 1x400W, 2x220W portable solar panels. With its MPPT (Maximum Power Point Tracking) smart algorithm, DELTA 2 can actively detect the voltage and current in real-time to reach the maximum power point with >98% efficiency. That means a more efficient charge than other brands.



Built to last 6x longer.

Finally… tech that’s made to last. Get years of regular use until hitting 80% of its original capacity. That’s down to its LiFePO4 battery chemistry giving you 3000+ full charge and drain cycles.



Ready for emergencies.

Use as an EPS (emergency power supply) to auto-switch to battery power when the grid goes down. Great for blackouts to keep your essentials running.



Part of an ever-growing ecosystem.

DELTA 2 is just the start. Link with a wide variety of EcoFlow products such as portable solar panels, the Wave portable air conditioner, extra batteries and so much more. All to deliver a one-stop power solution for your family.



Portable & light.

Designed so you can take power anywhere, DELTA 2 weighs about as much as a medium-sized dog. Compared to generators, it’s portable, indoor-friendly, and light. Add on the waterproof bag and you can use it outdoors in any weather too.



You've got our word.

With a 5-year extended warranty, you can rest easy knowing you've got a unit built to last.
