With compatible solar panels and suitable sunlight conditions, you can reduce your reliance on traditional grid power.

Four Flexible Ways to Recharge

The DELTA 3 Classic can be recharged through multiple methods, including AC power, solar panels, a generator, and vehicle/alternator charging with compatible equipment. This flexibility makes it suitable for both home and mobile applications, allowing you to restore your energy supply even when a conventional wall outlet isn't available.

Fast <10ms UPS Backup

The built-in UPS function provides a switchover time of less than 10 milliseconds, helping maintain power to critical connected equipment when the primary power source is interrupted. This makes the DELTA 3 Classic particularly useful for NAS systems, servers, computers, networking equipment, and other sensitive electronics that benefit from rapid backup power.

Long-Lasting LiFePO₄ Battery

The DELTA 3 Classic uses durable LFP (LiFePO₄) battery cells designed for long-term performance. EcoFlow estimates a lifespan of approximately 10 years under proper usage, based on its internal simulation testing. The battery chemistry is designed to provide dependable energy storage for frequent everyday use and emergency backup applications.

Automotive-Grade Battery Protection

Built with automotive-grade full-tab LFP cells and an intelligent battery management system, the DELTA 3 Classic is designed for dependable operation. Its battery protection system helps guard against conditions including over-voltage, overload, over-temperature, short circuit, low temperature, low voltage, and overcurrent.

Whisper-Quiet Operation

The DELTA 3 Classic is engineered for quiet operation, producing as little as 30dB under a 600W load. This makes it suitable for use inside the home, at night, in offices, RVs, campsites, and other environments where excessive noise can be disruptive.

Smart Energy Management with the EcoFlow App

Connect the DELTA 3 Classic through Wi-Fi and Bluetooth using the EcoFlow App. The smart control system lets you monitor battery status, power consumption, charging activity, and energy usage from your mobile device. EcoFlow's smart energy features also provide tools such as scheduled charging and discharging, helping you manage energy more efficiently.

Storm Guard for Emergency Preparedness

With supported EcoFlow App features, Storm Guard Mode can automatically prepare the power station when extreme weather alerts are detected. This provides an additional layer of preparedness by helping ensure backup energy is available before severe weather causes a power interruption.

Power Multiple Devices at Once

The DELTA 3 Classic provides multiple charging and output options for powering a variety of devices. The US version includes AC outlets, USB-A, and USB-C outputs, including a 100W USB-C port for compatible high-power USB-C devices such as laptops. The exact number and configuration of outlets can vary by regional version.

Portable Yet Powerful

Despite its 1kWh-class capacity, the DELTA 3 Classic remains relatively compact for its power level. It weighs approximately 12.1kg (26.7 lbs) and measures approximately 398 × 200 × 283mm, making it practical to store at home and transport for camping, RV trips, outdoor work, and emergency situations.
