Frequently Asked Questions

What is the battery capacity and how long does it last?

Delta Max 1600 has a 1,602 Wh battery (2,016 Wh for Delta Max 2000 variant) and maintains around 80% capacity after approximately 800 charge cycles—equivalent to best practices indicating about 2–3 years of heavy use or much longer under lighter use.

Can I expand the energy storage?

Yes. You can add up to two EcoFlow Delta Max extra batteries, doubling or even tripling the capacity (up to approximately 6,048 Wh total)

How fast does it recharge?

Using EcoFlow’s X‑Stream AC fast charging, it charges from 0–80 % in about 65 minutes and reaches 100% in around 1.6–1.8 hours at full AC input (~1,600 W). You can also charge it via solar (up to 800 W) or car, and combine sources to boost total input up to 2,600–3,000 W.

Is UPS mode supported?

Yes. In Emergency Power Supply (EPS) mode, Delta Max switches to battery backup in under 30 milliseconds when grid power fails—essentially functioning as a UPS

Can I use and charge it at the same time?

Absolutely. The Delta Max supports pass-through charging: you can power devices while simultaneously charging from AC, solar, or car inputs .

What battery care is recommended for longevity?

Store between 20°C–30°C, avoid extreme temperatures (below −10°C or above 45°C), and if unused for more than three months, discharge to about 30% and then recharge to 60–85% every quarter.

What kind of ports and power output does it provide?

Delta Max includes 4 pure sine AC outlets (2,000 W continuous, 4,600 W surge), 2 USB‑C (100 W), 2 USB‑A fast‑charge, 2 USB‑A standard, a 12 V car output, and 2 DC5521 ports—supporting up to 13 devices at once.
