The EcoFlow Alternator Charger Plus 1000 is a 1 kW DC-DC charger that turns a vehicle's alternator into a fast top-up source for a portable power station and adds an integrated 300 W solar input for stationary charging. It refills a compatible unit up to ten times faster than a standard 12 V cigarette lighter, delivering about 1 kWh per hour of driving. The 1.7 kg housing is protected to IP4X and communicates over Bluetooth for live status and mode changes in the EcoFlow app.

• Up to 1000 W of continuous alternator charging, around 1 kWh per hour behind the wheel — roughly ten times faster than a 12 V cigarette-lighter connection.
• Dedicated 300 W solar input (11–60 V, 15 A max) built into the same unit, so the same hardware handles panels when the vehicle is parked.
• Three modes: alternator charging, reverse charging into the starter or house battery and low-current maintenance that extends camper battery life.
• Integrated ignition-sense line in the input cable starts and stops charging with the engine, without manual switching.
• Adaptive output-voltage matching, gallium nitride switching and a 125 A safety fuse guard against overload and short circuits.
• Bluetooth link exposes real-time state of charge, temperature and mode selection to the EcoFlow app.
• IP4X ingress protection makes the unit tolerant of dust and debris in a technical compartment.
