Vehicle-Powered Backup Power for Everyday Homes
Use your daily commute / drive to power your essentials.
The DriveCharge™ Home Backup – Core system captures energy while you drive and stores it for use later at home — during power cuts, peak pricing hours, or whenever you want more control over your electricity use.
Built around the EcoFlow DELTA 2 Max, this system provides reliable backup power for everyday essentials without rewiring, generators, or permanent installation.
Optional upgrades available separately: extra batteries, portable solar panels, professional installation.
While you drive, your vehicle’s alternator feeds power into the EcoFlow alternator charger, safely charging the power station.
A typical daily drive can comfortably cover evening essentials and overnight device use.
Designed for everyday reliability — for longer runtimes, consider the Plus or Extended systems.
| Feature | Core | Plus | Extended |
|---|---|---|---|
| Total Capacity | 2048 Wh | 4096 Wh | 6144 Wh |
| Alternator Charging | 800 W | 800 W | 800 W |
| Typical Runtime | Evening essentials | Overnight + morning | Multi-day essentials* |
*Runtime depends on load management and driving time.
Clear installation instructions are included. Many mechanically minded customers install the alternator charger themselves, or use a local auto electrician.
Auckland customers: EcoFlow professional installation is available at $180 + GST per hour. Most installs are completed in 1–2 hours. Installation is arranged and billed directly by EcoFlow.
