How DELTA 2 prepares your home.

1-3kWh Expandable Energy Storage

Energy for the long haul.

Storing energy in a battery means you can power things for hours or days on end indoors or out. All without access to the grid. DELTA 2 lets you store 1kWh. In other words, it’s a ton of energy to power your essentials. Unlike smaller batteries, it can keep refrigerators, phones, and even hotplates powered for extended periods.

It’s the fastest charging in the industry.

X-Stream tech means you can charge from 0-80% in 50 mins*, that’s faster than you’ll pack your trunk for the next road trip.To iterate just how fast that is–it’s 7x faster than other power stations on the market.

*Graph represents 0-80% charge speeds achieved in lab conditions. 0-100% charge takes 80 minutes.

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.

Pick from a range of solar panels to get the speed you need (110W, 160W, 220W, 400W). With that, you’ve got access to free energy anywhere.

It’s sustainable in more ways than one.

LFP Battery Chemistry

Built to last 6x longer.

Finally… tech that’s made to last. Get 10 years of daily use until hitting 80% of its original capacity. That’s down to its LiFePO4 battery chemistry giving you 3000+ full charge and drain cycles and 6x longer than industry average.
