ECOFLOW DELTA 3 CLASSIC

EcoFlow DELTA 3 Classic - Portable Power for Home and Everyday Use

The EcoFlow DELTA 3 Classic Portable Power Station is designed to provide backup electricity for essential home electronics, office equipment and compatible household appliances. Its 1024Wh battery and 1800W rated AC output make it suitable for users who need portable power during grid interruptions, outdoor activities or work away from conventional electrical outlets.

With multiple charging options, app connectivity and a compact design, the DELTA 3 Classic offers a practical alternative to fuel-powered generators for compatible electrical loads.

1024Wh Battery Capacity for Essential Backup

The DELTA 3 Classic features a 1024Wh (1.024kWh) battery rated at 51.2V and 20Ah. This provides stored energy for compatible devices such as routers, laptops, lighting, televisions and selected appliances.

Actual runtime depends on the connected equipment's power consumption, inverter efficiency and operating conditions. For example, devices that draw relatively little power can operate for longer than high-consumption appliances. Calculate the expected energy demand before relying on the power station for extended backup.

1800W Rated Output with X-Boost Technology

The DELTA 3 Classic delivers 1800W of rated AC output and a surge rating of 3600W. This allows it to operate many compatible household and professional devices, provided their continuous power consumption and startup requirements remain within the unit's limits.

EcoFlow's X-Boost technology supports selected appliances with power requirements above the standard rated output, up to 2400W under compatible conditions. X-Boost does not guarantee that every appliance rated above 1800W will operate normally. Check appliance compatibility and performance requirements before connecting high-power equipment.

LFP Battery Technology for Long-Term Use

The power station uses lithium iron phosphate (LFP or LiFePO4) battery chemistry. EcoFlow describes an estimated service life of approximately 10 years under its stated usage assumptions. Actual battery lifespan depends on charging habits, operating temperature, usage frequency and storage conditions.

The battery management system also incorporates protections designed to help manage operating conditions and protect the unit during use.

Fast AC Charging and Solar Compatibility

The DELTA 3 Classic supports AC charging at up to 1400W and can recharge from 0–80% in approximately 45 minutes, with a full charge taking approximately 60 minutes under specified conditions.

For users seeking solar-powered backup, the unit supports solar input up to 500W. EcoFlow also lists alternator charging through a compatible 500W Alternator Charger, sold separately. Solar charging time depends on sunlight, panel orientation, temperature and the panels' actual output.

USB-C Charging for Laptops and Mobile Devices

The DELTA 3 Classic includes two USB-C ports, one rated up to 100W and the other up to 30W, for compatible laptops, tablets, smartphones and other electronics. A USB-A port provides an additional charging option.

Two AC outlets are available for compatible appliances and electronic equipment. The model does not include a dedicated 12V car output or extra-battery expansion port, so users should confirm these limitations before purchasing.

UPS Function for Computers and Networking Equipment

With a specified switching time of approximately 10 milliseconds, the DELTA 3 Classic can help maintain power to compatible computers, routers and other electronics during brief interruptions.

It should not be assumed to replace every dedicated UPS system. Confirm that connected equipment can tolerate the switching time, especially for critical applications.

Compact Design and Quiet Operation

Weighing approximately 12.1kg, the DELTA 3 Classic is designed for portability between rooms, workspaces and outdoor locations. EcoFlow specifies noise below 30dB at a 600W load under stated test conditions.

Its combination of a 1kWh-class battery, 1800W output and rapid charging makes it suitable for users who need portable backup power without the emissions and fuel requirements of a conventional petrol generator.
