EcoFlow 500W Alternator Charger — Charge Your Power Station 5× Faster While You Drive
The EcoFlow 500W Alternator Charger captures surplus power from your vehicle's alternator and feeds it directly into your EcoFlow power station — charging 1kWh in as fast as 2.1 hours while you drive, 5× faster than a cigarette lighter. A 3-in-1 charger, battery maintainer, and jump starter, it's compatible with all EcoFlow and most third-party portable power stations.
⚠ Reverse Charging & Battery Maintenance Require XT150 Cable (Sold Separately). The 500W Alternator Charger ships with an XT60 cable. Reverse charging and battery maintenance functions are only available with the XT150 cable, and require an EcoFlow DELTA Series product.
⚠ DELTA Pro Requires Adapter. A DELTA Pro to Smart Generator Adapter (sold separately) is required to connect the 500W Alternator Charger to a DELTA Pro.
⚠ Verify Alternator Capacity. The 500W Alternator Charger's maximum power draw must be within your vehicle alternator's rated output. Check your vehicle or alternator manual before use.
