DriveCharge™ Extended Runtime System – Vehicle-Powered Backup & Work Power
🚗⚡ DriveCharge™ Extended Runtime System
Vehicle-Powered Backup & Work Power with Maximum Runtime
The DriveCharge™ Extended Runtime System is designed for customers who want serious energy capacity without stepping into complex fixed installations. By combining the EcoFlow DELTA 2 Max with two Extra Batteries and the EcoFlow Alternator Charger, this system delivers long-duration backup and mobile work power — replenished simply by driving.
This system is ideal for extended outages, off-grid work, mobile trades, rural properties, and anyone who wants to use vehicle-generated energy to run essential loads across multiple days.
🔧 What’s Included
- EcoFlow DELTA 2 Max Portable Power Station (2048Wh)
- 2 × EcoFlow DELTA 2 Max Extra Batteries (total system ≈6144Wh)
- EcoFlow 800W Alternator Charger
- XT150 charging cables & required EcoFlow connectors
- 15A Heavy-Duty Extension Lead (for home backup use)
⚙️ How the DriveCharge™ Extended Runtime System Works
- The alternator charger captures energy from your vehicle while driving
- Power is stored across the DELTA 2 Max and two Extra Batteries
- At home or on site, the system delivers clean 230V power instantly
- Driving time refills the system — no fuel, no generators, no rewiring
With up to 800W of alternator charging, you can recover roughly 0.8kWh per hour of driving, making daily vehicle use a meaningful source of energy for extended runtime scenarios.
🔌 What This System Can Power
- Lighting, internet, Starlink & devices
- TVs and entertainment systems
- Fridge or fridge/freezer for multiple days
- Power tools, chargers, compressors (within 2400W continuous limit)
- Mobile workshops, sheds, and rural workspaces
- Extended outage resilience with reduced load management
Note: This system increases runtime (energy capacity), not inverter size. High-draw heating or cooking appliances should be assessed individually.

❓ Frequently Asked Questions
Does adding extra batteries increase charging speed?
No. Adding Extra Batteries increases total energy storage (Wh), not charging speed. The EcoFlow Alternator Charger continues to charge the system at up to 800W. With more stored energy available, you simply gain longer runtime and greater outage resilience.
What is the maximum capacity of this system?
The EcoFlow DELTA 2 Max supports up to two EcoFlow Extra Batteries, giving a total usable capacity of approximately 6144Wh. This Extended Runtime system represents the maximum expandable configuration available for the DELTA 2 Max platform.
Is professional installation required?
Professional installation is not mandatory. The EcoFlow Alternator Charger includes clear instructions and wiring diagrams, and many mechanically minded customers choose to install it themselves. Alternatively, a local auto electrician can assist.
Is this system only for off-grid homes?
Not at all. This system is ideal for both grid-connected and off-grid homes. It’s especially useful for customers who drive regularly and want to reduce peak electricity use, improve outage resilience, or power tools and essentials during extended outages.
What if I need more power than this system provides?
If you require more than ~6kWh of storage or higher continuous output, EcoFlow’s DELTA Pro–class systems are the next step up. We’re happy to help assess the right option for your needs.
Accessories & shipping:
Non-EcoFlow accessories (such as extension leads) may vary in appearance. Components may ship separately depending on supplier location and availability.
