🚗⚡ DriveCharge™ Home Backup – Plus

Vehicle-Powered Backup Power with Extended Runtime

Same fast charging. Twice the usable energy.

The DriveCharge™ Home Backup – Plus system builds on the Core setup by adding a Smart Extra Battery, giving you more runtime and more margin without changing how the system charges or operates.

This is the most popular option for households wanting reliable overnight backup power without stepping into larger, more expensive systems.

🔋 What’s Included

  • EcoFlow DELTA 2 Max Portable Power Station
  • EcoFlow DELTA 2 Max Smart Extra Battery (≈ 4 kWh total storage)
  • EcoFlow 800W Alternator Charger
  • 15A Heavy-Duty Extension Lead

⚡ How the Plus System Works

Charging behaviour is identical to the Core system — you simply store more energy.

  • ≈ 0.8 kWh gained per hour of driving
  • Predictable daily charging
  • No additional complexity

🏡 What the Plus System Can Support

  • Lighting, internet, and devices
  • TV and entertainment systems
  • Fridge or fridge/freezer overnight
  • Extended outage resilience

📊 Compare DriveCharge™ Systems

System Capacity Best for What it can cover Not ideal for
Home Backup – Core ~2 kWh Evening essentials Wi-Fi, lights, devices, TV, short fridge runtime All-night heavy loads
Home Backup – Plus ~4 kWh Overnight + more headroom Essentials + longer fridge runtime + better outage resilience Heating / cooking appliances
Home Backup – Extended ~6 kWh Multi-day essential backup* Essentials for longer outages with careful load management High-draw whole-home running

*Runtime depends on what you power, how you manage loads, and how much you drive/charge.

❓ Frequently Asked Questions

No — charging speed is the same. The benefit of the extra battery is longer runtime because you’re storing more energy.

Yes. You can expand capacity with additional compatible batteries if your backup needs grow over time.

It can. If you commute/drive regularly, you can shift some evening usage off peak-time grid power by using the stored energy at home.

Accessories & shipping:

  • The included 15A extension lead is not manufactured by EcoFlow, and its colour/appearance may vary.
  • Components may ship separately and arrive in multiple deliveries.
