This little box provides on-demand power when off the grid

EcoFlow’s Alternator Charger is a device designed for installation in pickup trucks, vans, or RVs to charge a power station for gear. It can produce up to 800W while the vehicle is running, allowing for quick charging of the Delta 3 power station in just over an hour of driving. This provides eight times more power than a typical 12V cigarette lighter jack and is a convenient solution for on-the-go charging needs.
