Welcome to a new era of portable power solutions with the EcoFlow DELTA 3 Max Plus Power Station. This powerful tool ensures that your essential devices remain charged and functional, whether you're hosting a backyard party, embarking on an adventurous RV trip, living off-the-grid, or working on a remote site. With this level of powerful, reliable technology at your fingertips, you will always be prepared for any situation that life throws your way.
Real-World Applications Home Backup, RV Travel, Off-Grid Living, Mobile Worksites
The versatility of the EcoFlow DELTA 3 Max Plus truly shines through its wide array of applications.
As a dependable home backup source, it ensures your life doesn't skip a beat during unexpected power outages. A power outage does more than shut off the lights. It disrupts your comfort, your safety, and your ability to stay connected. Without reliable backup, freezers thaw, medical devices fail, and your home can be left vulnerable for days at a time.
With a 4,096Wh base capacity expandable to 12,288Wh, it provides extended runtimes that keep your home powered for as long as needed. Its 3,000W AC output with a 4,500W surge runs even the most demanding appliances—everything from central air conditioners and washers to heavy-duty tools and electronics.
For RV enthusiasts and off-grid adventurers, its portability and high capacity provide reliable energy solutions amid natural settings.
Mobile worksites benefit from its robust power output, empowering productivity wherever your projects take you.

Transition seamlessly from home to rugged outdoors, all while keeping the same powerful support that only the DELTA 3 Max Plus can deliver.
Fast recharge technology brings it to 80 percent in just over an hour, and solar input allows you to generate renewable energy directly from the sun for complete independence. Quiet, emission free, and safe indoors or outdoors, the DELTA 3 Max Plus gives you the security of uninterrupted power without the drawbacks of gas.
With the DELTA 3 Max Plus, you are not just preparing for outages. You are ensuring total energy freedom for your home, RV, or off-grid life.

Gotcha with the title, I have purchased several items from OBP, like a repeat offender. I’m glad I stumbled across their website, every product I purchased has arrived on time and in great condition. As long as I have a need for their products, I will always be a customer, or repeat offender.
