2,048Wh of portable storage and 3,000W continuous AC output, with battery expansion for longer runtime.
EcoFlow DELTA 3 Max Plus Portable Power Station
The EcoFlow DELTA 3 Max Plus combines a capable inverter with expandable energy storage for selected backup loads, mobile work and off-grid use.
It is a useful step up when smaller power stations cannot handle your appliance wattage. For longer stays or outages, compatible extra batteries can increase runtime without replacing the base unit.
2,048Wh Capacity
3,000W AC Output
Expandable Storage
Dual Solar Inputs
LFP Battery
Higher Appliance Capability
Run suitable equipment within the inverter and outlet limits. Check starting requirements as well as normal consumption, especially for motors and compressors.
Storage That Can Grow
Add compatible batteries when you need longer between charges. Choose capacity around your daily consumption and available charging supply.
Flexible Recharging
Use mains power, suitable solar panels or compatible vehicle-charging accessories. Panels, alternator chargers and additional cables are sold separately.
Monitor Your Setup
Use the EcoFlow app to view system status and supported settings. Keep an eye on consumption so your stored energy lasts for the tasks that matter.
🔧 What’s Included
- 1 × EcoFlow DELTA 3 Max Plus Portable Power Station
- AC charging cable
- Manuals and warranty documentation
Extra batteries, solar panels, alternator charger and additional connection accessories are not included.
⚡ What Can It Run?
- Fridges and freezers with compatible starting requirements
- Lighting, laptops, TVs and communications equipment
- Suitable kettles and portable cooking appliances
- Compatible power tools and battery chargers
- Selected pumps and other equipment within its limits
The combined AC load must remain within the power station’s continuous rating, and each outlet has its own limit. A high total inverter rating does not mean one outlet can supply the full output.
Output and runtime are different: A power station may be capable of starting an appliance but only run it briefly if consumption is high. Heaters and cooking appliances can use stored energy quickly.

Larger configurations are possible with supported higher-capacity batteries and the correct accessories. Contact us to confirm the complete arrangement before ordering.
Adding batteries increases stored energy—not continuous inverter output. Extra batteries and expansion adapters are purchased separately.
☀️ Solar & Vehicle Charging
The dual solar inputs support up to 1,000W combined, with a maximum of 500W per input. Panel arrangements must also satisfy each input’s voltage and current limits.
Do not select panels by wattage alone. Check cold-weather open-circuit voltage, operating voltage, current and cable requirements before connection.
Compatible EcoFlow alternator chargers provide another charging option while travelling. The required adapter or output cable depends on the charger and connection arrangement; ask us to check these before purchasing.
🏕️ Planning Your Runtime
Start with the wattage of each appliance and how long you expect to use it. For cycling equipment such as a fridge, daily energy consumption is more useful than the compressor’s running wattage alone.
Nominal battery capacity is not the same as usable AC energy delivered. Conversion losses, temperature, standby consumption and battery condition all affect runtime.
For regular off-grid use, your charging supply must replenish your daily consumption. Extra storage alone does not make a system self-sufficient.

Frequently Asked Questions
Can it run a kettle or cooking appliance?
Many suitable appliances fall within its output capability, but check the appliance wattage, individual outlet rating and any other loads running simultaneously. High consumption reduces runtime quickly.
Will it run power tools?
It can run compatible tools within its limits. Motors, compressors and some workshop equipment have demanding starting characteristics, so check the exact equipment rather than assuming compatibility.
Can I add two extra batteries?
Yes, using supported batteries and the required EcoFlow Extra Battery Expansion Adapter. Ask us to confirm the batteries, cables and adapter for your proposed setup.
Are solar panels included?
No. Select suitable panels and connection cables separately, or choose a clearly specified solar bundle.
Can I use it as a UPS?
EcoFlow specifies a switchover time below 10ms, but this is not zero-transfer-time protection. Check and test compatibility with your equipment. Do not use it as the sole supply for life-support or safety-critical equipment.
Does X-Boost increase its continuous output?
No. X-Boost may operate selected higher-rated appliances at reduced voltage. It does not increase the rated continuous inverter output and is unsuitable for some equipment.
