Catching Up With The Times

The EcoFlow Delta 2 also packs a battery upgrade, but it follows the theme of subtle and unnoticeable changes. Compared to the first-gen model, the capacity is similar at 1,024 Wh, but the output has been bumped up a bit to a total of 1,800 watts without the surge. With EcoFlow’s proprietary X-Boost technology, that output can go all the way up to 2,200 watts. The most important upgrade, however, is the change of battery type from NCM to LFP — LiFePO4 is considered to be a safer and more stable battery technology, and it’s the same kind that’s used in electric vehicles.

There are also now 15 output options available on the power station to keep up with the growing demand, even in small houses. The most important here is that the two USB-C ports on the front now support 100 watts of output and the Power Delivery (PD) standard. That’s enough to charge hungry laptops like MacBook Pros, for example, and everything in between. Like before, there are dedicated buttons to turn each group of power output on or off, but the button on the front has been given a new color to make it more visible even in the dark.

The back of EcoFlow Delta 2 has all of the AC and DC output ports, as well as a flap that covers the two input options that we’ll get to later. Depending on your model, you’ll have four or six AC outlets with a total 1,800-watt output or 2,700-watt surge, enough for even a microwave or small fridge. DC output options include two barrel-type ports and a car charger, which is also hidden behind a flap of its own.

If that 1,024 Wh capacity sounds insufficient, you can expand the Delta 2 model’s power if you have other EcoFlow products lying around. In particular, an EcoFlow extra battery kicks it up to 2 kWh, while hooking it up to the larger EcoFlow Delta Max will produce a total of 3 kWh of power. At that point, you do lose a bit of the portability, but there will always be emergency cases where you’ll need more juice in the same place, like during a power outage at home.
