What this unit is for
An energy-technology company first and an outdoor brand second: the pitch is a smart, expandable energy ecosystem rather than a single box.
Best suited to: Buyers who want one system to grow from camping into home backup. Less suited to: Buyers who want the lowest cost per watt-hour and will never use an app.
Phones, lights, a laptop. Carryable in one hand.
