The EcoFlow Alternator Charger Plus 1000 is a 1000W in-vehicle DC-DC charger that lets you top up a portable power station while you drive, up to 10x faster than a standard car cigarette socket. With 700W of alternator input and an additional 300W solar input (when paired with the optional solar input cable), it adds 1kWh of charge in roughly 1 hour, making it ideal for motorhomes, 4WDs, freedom campers, and trade vehicles travelling between sites.
It supports the EcoFlow DELTA 3 Plus and EcoFlow DELTA 3 Max Plus directly via the included XT150 output cable, and also supports the EcoFlow DELTA Pro 3 with the addition of the EcoFlow Smart Generator Adapter. Reverse charging protects the starter battery, and the EcoFlow app gives you real-time control over charging modes, starter battery status, and power station charge level. Plug-and-play installation, IP4X dust protection, and fanless natural cooling make it a reliable long-term fit for road trips and worksite power. Key Features:
