EcoFlow has introduced four portable power stations in its DELTA Gen4 and RIVER Gen4 lines. All include Emergency Power Mode, which the company says reserves a small amount of electricity after the display reaches 0%; DELTA models are on sale in the U.S., while RIVER presales are scheduled to start November 24.
EcoFlow has launched four portable power stations in its DELTA Gen4 and RIVER Gen4 series, each with an Emergency Power Mode that the company says keeps a small amount of electricity available after the battery indicator reaches 0%. The reserve is intended for limited emergency use, such as charging a phone or powering a light, rather than continuing to run appliances as normal.
The two larger DELTA Gen4 models are aimed at home backup. EcoFlow lists the DELTA 3000 Gen4 with a 3,072-watt-hour battery and the DELTA 3800 Gen4 with 3,763Wh. The larger unit can be expanded with additional batteries to a stated total capacity of 12 kilowatt-hours. Both are rated for 3,600 watts of continuous output and 7,200W of surge power, according to the company.
EcoFlow says both DELTA models draw 14 watts with AC enabled and no load, falling to 3W in standby. Its Fridge Runtime Boost feature is designed to reduce power use between refrigerator cooling cycles. The company claims refrigerator runtimes of up to 58 hours for the DELTA 3000 and 70 hours for the DELTA 3800; actual runtime will depend on the refrigerator and operating conditions.
The smaller RIVER Gen4 stations target camping and travel. The RIVER 260 Gen4 has a 256Wh battery and 300W output and weighs just over six pounds. The RIVER 520 Gen4 offers 512Wh and 500W output in a 10-pound unit. EcoFlow lists 140W bidirectional USB-C on both and says the 260 can charge from 0% to 80% in 42 minutes, compared with 50 minutes for the 520.
Emergency Power After the Display Hits Zero
Emergency Power Mode addresses a practical problem for people relying on portable batteries during outages or outdoor trips: a displayed zero can otherwise leave no obvious reserve for a final phone charge or emergency light. EcoFlow says the feature preserves a small amount of power for those limited tasks. The announcement does not establish that the reserve can run larger equipment, and the mode should not be read as extending ordinary operating capacity.
The lineup also spans two distinct uses. DELTA’s higher output and expandable capacity are pitched for household backup, while the lighter RIVER units are designed for portable, lower-power needs. EcoFlow’s runtime and low-consumption figures could help buyers compare the stations, but they are company specifications and claims; real-world performance will vary with connected devices and use.

Four Models Across Two Product Lines
The announcement groups the new products into DELTA Gen4 and RIVER Gen4, rather than describing a single replacement model. DELTA offers the larger battery capacities and output figures, with an expansion option on the 3800. RIVER offers smaller batteries and lower output in lighter designs for users prioritizing portability.
According to the source report, the DELTA 3000 Gen4 and DELTA 3800 Gen4 are on sale in the United States at introductory prices of $1,299 and $1,699, respectively. RIVER Gen4 presales are scheduled to begin November 24, with pricing not yet announced in the supplied information.

Reserve Size and Test Conditions
The source does not specify how much electricity Emergency Power Mode reserves, whether users can control when it activates, or how long the reserve can power particular devices. It also does not explain whether the feature works identically across all four models or whether performance changes with battery age, temperature, or storage conditions.
Several performance claims lack full test details in the supplied report. No test setup is given for the refrigerator runtime estimates, and the company’s specifications have not been independently verified here. The source also does not provide a price for either RIVER station or a detailed schedule beyond the stated November 24 presale start.
Sales and RIVER Pricing Ahead
The DELTA 3000 Gen4 and DELTA 3800 Gen4 are listed as available in the United States at introductory prices. EcoFlow’s next stated sales milestone is RIVER Gen4 presales on November 24; pricing remains unannounced in the source material. Buyers awaiting those models will need the company’s sales details to compare their cost with the DELTA units.
Further product information could clarify the emergency reserve’s capacity and operating limits, as well as the conditions behind the refrigerator runtime estimates. Until those details are available, the 0% feature is best understood as a limited emergency reserve described by EcoFlow, not a guarantee that devices will continue running for a set duration.
Key Questions
What happens when an EcoFlow Gen4 station reaches 0%?
EcoFlow says Emergency Power Mode keeps a small reserve available after the battery indicator reads 0%, for limited uses such as charging a phone or powering an emergency light. The amount of reserve and its runtime are not specified in the supplied report.
