## Description

EF ECOFLOW500W Alternator Charger, 3-in-1 Fast DC-DC Charger for Portable Power Stations, Car Battery Charger & Jump Starter 5× Faster Than Cigarette Chargers, Charges 1kWh in 2.1 hr

## Features

- [5× Faster Than a Car Cigarette Lighter Charger] The 500W Alternator Charger replenishes 1kWh of energy to your portable power station within a 2.1 hour drive, tapping surplus alternator power to keep phones, coffee makers, lights, and more running on the move.
- [3-in-1 Functional Design] Integrates alternator charging, vehicle battery maintenance, and jump-start capability into one compact unit, ensuring your power station tops up, your battery stays healthy, and you're ready for sudden starts.
- [Easy-Install System for Vanlife] Seamlessly integrates with 12V/24V SUV house batteries using plug-and-play wiring to extend runtime on overland and vanlife adventures. Lightweight and portable, it also detaches for off-grid power when you hit the great outdoors.
- [Access the EcoFlow App Anywhere] View real-time vehicle energy usage, power consumption, and charging status remotely. Monitor temperature, appliance loads, and battery health from your smartphone, no matter where you roam.
- [2-Year Service & Vehicle Protection] Built with GaN technology for high-efficiency DC-DC conversion without overheating. Comprehensive safeguards protect against reverse polarity, overcurrent, shorts, and voltage spikes throughout your journeys.
- When using an XT60 cable, the Alternator Charger switch on the device must be manually turned on and the charging function enabled in the app before charging can begin. Therefore, if planning to use the XT60 cable for output, avoid concealed installation of the Alternator Charger in advance.
