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.
to get the speed that meets your need (110W, 160W, 220W & 400W).

Lasts 6x longer

It has been designed for stability, even if heavy damage or accidents occur. The built-in management system regulates vitals to keep your beloved safe and secure.
