EcoFlow\u2019s Alternator Charger<\/a> is a device you install in your pickup truck, van, or RV to charge the giant power station you carry to keep all your gear running.<\/p>\n<\/div>\n While your vehicle\u2019s on, the Alternator Charger produces up to 800W. That\u2019s about eight times more power than you can typically extract from a 12V cigarette lighter jack, and it\u2019s enough to charge EcoFlow\u2019s new 1kWh Delta 3<\/a> from zero to full in a little over one hour of driving. It takes five hours if you\u2019re traveling with EcoFlow\u2019s larger 4kWh Delta Pro 3<\/a>.<\/p>\n<\/div>\n It\u2019s also clever enough to reverse the flow of electrons, using the power station to maintain your starter battery with a trickle charge or jump-start it back to life. When you return home from the job site or vacation, those big-ass portable batteries can be connected to EcoFlow\u2019s $200 balcony solar kit<\/a> to help offset your energy bill and provide emergency power during a blackout<\/a>.<\/p>\n<\/div>\n EcoFlow\u2019s Alternator Charger is far from an industry first, and it uses proprietary connectors that only work with Ecoflow\u2019s own batteries. But the company brings simplicity, elegance, and a superior user experience to a product usually designed for electricians and mechanics.<\/p>\n<\/div>\n After 3,700 miles (6,000km) of testing, I can say that the $599 Alternator Charger could be a game-changer for many. It allowed my wife and I to live and work carefree from a Sprinter van this summer, comforted by all the modern conveniences afforded by so much on-demand power.\u00a0<\/p>\n<\/div>\n
