EcoFlow DELTA 2 Max Smart Extra Battery Features:
Convenient recharging DELTA 2 Max and its Extra Battery charge and discharge in unison. Whether you’re recharging DELTA 2 Max from solar panels, AC outlets, a vehicle, or our Smart Generator, the DELTA 2 Max Extra Battery will recharge alongside.
Independent in emergencies The extra battery even recharges directly from EcoFlow’s Smart Generator without DELTA 2 Max. That’s more recharging options to fit any situation.
LCD screen Get all the info on battery percent, time until full, time until empty, and more on the DELTA 2 Max Extra Battery LCD screen. Check the battery’s status anywhere on the EcoFlow app.
No fumes, No noise, No maintenance.
Fume-free: since power stations don't burn fuel, they don't produce emissions or fumes, making them a clean and eco-friendly alternative to gas generators.
Quiet: without internal noisy combustion engines, DELTA 2 Max is extremely quiet, even when charging.
Maintenance-free: There's no fuel to refill, no filters or fluids to change or mechanical parts that need constant maintenance.
World’s Fastest Recharging Methods
Industry's Fastest AC Recharging: Get an input of up to 1800W with X-Stream technology. Charge 0-80% in 68 min (1.1 hour)
Industry's Fastest AC + Solar Recharging: Charge to 80% in 43 min. Fully charge in about 1 hour.
Harness Clean Solar Energy For Fast Charging:
Fully charge with up to 1000W solar input in only 2.3 hours.
Power 99% of Essentials Industry-leading X-Boost Technology
A 2400W output powers up to 15 devices at once. Run some appliances with up to 3400W using X-Boost mode. That means during a power outage or blackout, you can continue to run your fridge, microwave, dryer, and more. Ideal power generator for backup power.
LFP Battery: 3000 cycles, 6× more than the industry average, for up to 10 years of everyday use
Premium LFP cells for long-lasting battery life. Using the same chemical makeup as Tesla batteries, DELTA 2 Max gives you 3000 complete cycles till it's down to 80% capacity. That's 6× more than the industry average of 500.
10 years of everyday use. If used once a day, it can be safely used for about 10 years.
Advanced BMS protection. Self-regulates voltage, current, and temperature. Charge safely with comprehensive protection.
Safe and stable for high performance even in warm temperatures.
Customized In-app Energy Management
Save more on electricity bills: Prioritize the use of solar energy via the EcoFlow app when using AC + solar dual charging. Starts and ends at any time you want to save energy bills by avoiding peak rates.
Experience peace of mind during power outages AC Always On Mode: power button stays on, even during a power outage or after the grid power is back, keeping appliances powered. Adjust energy sources to fit your needs: backup power reserve or energy savings.
Lower battery power reminder: Get a notification via the app when the battery hits a low.
Ultra-fast home backup switchover - <30ms EPS auto-switch
When a blackout occurs, the power station automatically switches to the battery supply mode in less than 30ms. It ensures a constant power supply to your devices.
Multiple levels of protection for safe and reliable use
Made from safe, robust materials and a sturdy one-piece design. It can withstand severe knocks and falls. Each port is reinforced to be resistant to wear and tear.
The modular electronic components fit together seamlessly and can be easily removed from the unit for maintenance. All wires are copper-plated and polymer-wrapped for enhanced cooling, safety, and strength.
Rubber anti-slip base.
A shell of the highest fire-resistant rating, 5VA. Comes with a strengthened handle.
The EcoFlow service team provides a 5 year warranty. Experience absolute peace of mind.
