Power Your Essential Appliances with Confidence
Whether you're preparing for a power outage or heading off-grid, the EcoFlow DELTA 3 is engineered to keep your essential devices running. Its 1,800W pure sine wave inverter safely powers sensitive electronics while handling larger household appliances. With 3,600W surge capacity, the DELTA 3 can accommodate devices that require extra startup power, and EcoFlow's X-Boost technology allows compatible appliances rated up to approximately 2,200W to operate efficiently.
From refrigerators and chest freezers to desktop computers, networking equipment, televisions, microwaves, coffee makers, CPAP machines, fans, lighting, cameras, and power tools, the DELTA 3 is built to provide dependable backup power wherever you need it.
Long-Lasting 1,024Wh LiFePO₄ Battery
At the heart of the DELTA 3 is a durable 1,024Wh Lithium Iron Phosphate (LiFePO₄) battery that delivers exceptional longevity and safety. Rated for approximately 4,000 complete charge cycles before reaching 80% of its original capacity, this advanced battery chemistry provides years of reliable daily use and emergency backup.
EcoFlow's intelligent Battery Management System continuously monitors voltage, current, temperature, and charging conditions while providing multiple layers of protection against overheating, overcharging, excessive current, short circuits, and other electrical issues. The result is dependable performance and peace of mind every time you use your portable power station.
Expandable Backup Power as Your Needs Grow
Your power needs can change over time, and the EcoFlow DELTA 3 is designed to grow with you. The built-in 1,024Wh battery can be expanded using compatible EcoFlow Smart Extra Batteries, allowing the system to reach approximately 5kWh of total energy storage, depending on the expansion battery selected.
Compatible expansion options include the EcoFlow DELTA 3 Smart Extra Battery, DELTA 2 Smart Extra Battery, DELTA 2 Max Smart Extra Battery, and DELTA Pro 3 Smart Extra Battery. This flexibility allows you to start with a compact portable solution today while adding longer runtime for future home backup, RV use, or off-grid applications.
Recharge Faster Than Ever
One of the DELTA 3's standout features is its incredibly fast charging capability. EcoFlow's advanced X-Stream technology allows the power station to recharge from 0% to 100% in as little as 56 minutes using a standard AC wall outlet. This rapid recharge means you'll spend less time waiting and more time prepared for whatever comes next.
The DELTA 3 also supports multiple charging methods, giving you the flexibility to recharge wherever you are.
- Fast AC wall charging
- Up to 500W solar charging with integrated MPPT technology
- Vehicle charging while traveling
- Compatible EcoFlow Alternator Charger
- Generator charging during extended outages
- Combined AC and solar charging for even faster energy replenishment
Whether you're at home, on the road, or completely off-grid, the DELTA 3 provides flexible charging options to keep your power station ready.
Reliable UPS Backup for Sensitive Electronics
The EcoFlow DELTA 3 features an integrated Uninterruptible Power Supply (UPS) with a transfer time of less than 10 milliseconds. When connected between utility power and compatible electronics, the DELTA 3 automatically switches to battery power during an outage, helping keep computers, internet equipment, security systems, and other critical electronics operating with minimal interruption.
This makes the DELTA 3 an excellent solution for home offices, remote workers, networking equipment, entertainment systems, and emergency communication devices.
Quiet, Clean Portable Power
Unlike traditional gasoline generators, the EcoFlow DELTA 3 operates without gasoline, engine oil, or exhaust fumes. Its whisper-quiet operation makes it ideal for indoor use, apartments, RVs, campsites, bedrooms, garages, workshops, and offices where low noise levels are important.
With zero fuel emissions during operation, the DELTA 3 offers a cleaner, safer, and more convenient portable power solution for both everyday use and emergency preparedness.
13 Convenient Output Ports
The DELTA 3 provides a wide selection of output ports, allowing you to power multiple devices simultaneously.
- 6 AC Outlets
- 2 USB-A Fast Charge Ports
- 2 USB-C 100W Ports
- 1 12V Car Outlet
- 2 DC5521 Outputs
The dual 100W USB-C ports are ideal for charging laptops, tablets, drones, cameras, smartphones, and other USB-C powered electronics without needing additional power adapters.
Smart Monitoring with the EcoFlow App
Using Wi-Fi or Bluetooth connectivity, the EcoFlow app gives you complete control over your DELTA 3 from your smartphone. Monitor battery percentage, input and output power, remaining runtime, charging speeds, firmware updates, battery settings, and more from virtually anywhere.
Additional smart features may include charging schedules, battery reserve settings, energy optimization, storm warning notifications, and remote system monitoring to help maximize your backup power system.
Compact Size with Big Performance
Despite its powerful performance, the EcoFlow DELTA 3 remains compact and portable. Weighing approximately 27.6 pounds, it is easy to transport between your home, vehicle, RV, campsite, or jobsite. Integrated handles and a space-saving design make it simple to store when not in use while providing serious backup power whenever it's needed.
