EcoFlow DELTA 3 Max Portable Power Station with 2048Wh LFP Battery and 68-Minute Charge

Full-Size Power in a Lighter Build:

The DELTA 3 Max houses a 2048Wh battery pack built from automotive-grade full-tab LiFePO₄ cells. EcoFlow's cell-to-chassis (CTC) construction - borrowed from electric vehicle manufacturing - integrates the cells directly into the unit's frame, trimming overall weight to 20.3 kg, which is 13% lighter than the previous-generation 2 kWh model. The result is a full-capacity power station that is genuinely manageable to move between the home, the car boot, and a campsite.

Fast Charging with X-Stream Technology:

X-Stream charging fills the DELTA 3 Max from 0 to 100% in approximately 68 minutes from a standard AC wall outlet, accepting up to 2300W of input. For solar users, the integrated XT-60 connector accepts up to 500W of solar panel input. These two sources can be combined simultaneously to reduce charge times further when sunlight is available.

X-Boost 3.0 and Reliable UPS Protection:

X-Boost 3.0 allows the DELTA 3 Max to power devices rated up to 3200W from its 2400W inverter, covering high-draw appliances that would otherwise exceed the unit's rated output. The built-in UPS function auto-switches to battery power in under 10 milliseconds when mains electricity is interrupted - fast enough to prevent NAS systems, routers, and other sensitive equipment from dropping out. Storm Guard Mode monitors severe weather forecasts and can trigger automatic AC charging before an outage occurs.

Quiet, Connected, and Long-Lasting:

Operating noise is rated at 25dB or less under typical load conditions, making the DELTA 3 Max suitable for use inside a home, a van, or a tent without causing disturbance. OASIS 3.0 app connectivity via Wi-Fi and Bluetooth gives full monitoring and control from a smartphone. The LFP cells are rated to 3,500 cycles before dropping to 80% of original capacity, giving many years of regular use before any performance reduction is noticed.

What's Included in the Box

• 1 x EcoFlow DELTA 3 Max Portable Power Station
• 1 x AC Charging Cable
• 1 x Car Charging Cable (DC5525 to cigarette lighter)
• 1 x DC5525 to XT60 Cable (solar input)

Setup and Care

Getting Started:

Connect the AC charging cable to a standard 230V wall socket to begin charging. Download the EcoFlow app (OASIS 3.0) and pair via Bluetooth for initial setup, then connect to your home Wi-Fi for remote monitoring. The unit is ready to use straight from the box once charged.

Charging Options:

The DELTA 3 Max supports wall AC charging (up to 2300W), solar panel input (up to 500W via XT-60), and car socket charging simultaneously where conditions allow. For solar charging, compatible EcoFlow solar panels connect directly using the included DC5525 to XT60 cable.

Getting the Most from the Battery:

LFP chemistry does not require full charge and discharge cycles to maintain health - partial charging is fine for everyday use. Storing the unit at approximately 30-80% charge during long periods of non-use helps to maintain cell longevity. The DELTA 3 Max is designed to operate safely between -10°C and 45°C.

Keeping It in Good Condition:

Wipe the exterior with a dry or lightly damp cloth - avoid moisture near the ports and ventilation areas. Keep ventilation grilles clear of obstructions during use, particularly when running high-draw appliances. The unit should be stored indoors in a dry environment, away from direct heat sources.
