Description
Turn every mile you drive into meaningful battery charging with the EcoFlow DELTA 3 plus 800W Alternator Charger bundle. By connecting directly to your vehicle’s alternator terminals, the 800W Alternator Charger delivers up to 800W of charging power from your vehicle’s engine, adding approximately 800Wh of energy to the DELTA 3 for every hour of driving. For overlanders, van lifers, and road trip campers, this means your power station stays charged from driving alone.
The DELTA 3 holds 1,024Wh of LiFePO4 storage expandable to 5kWh, and delivers 1,800W of continuous AC output with 2,200W X-Boost mode. On a typical daily commute or road trip, the 800W alternator charger can bring a depleted DELTA 3 back to near-full charge, making every drive a productive recharging session. Unlike standard 12V car outlets limited to around 120W, the direct alternator connection bypasses that bottleneck entirely, delivering over 6 times more charging power from the same vehicle.
The 800W Alternator Charger is also a 3-in-1 automotive tool: it functions as a 12V vehicle battery maintainer during storage periods, and as an emergency jump starter for dead vehicle batteries. Both roles add practical value beyond EcoFlow charging alone. Installation connects to your alternator’s charge circuit and is straightforward for users with basic automotive electrical experience.
Sub-15ms UPS, multiple AC and USB outputs on the DELTA 3. Backed by a free 5-year warranty on the DELTA 3.
