EcoFlow launches high-capacity DELTA Gen4 portable power stations in Japan

EcoFlow Technology Japan has announced the release of the DELTA 3000 Gen4 and DELTA 3800 Gen4 portable power stations. The new series features battery capacities exceeding 3,000Wh and a rated AC output of 3,000W, designed to power high-consumption appliances such as refrigerators and microwave ovens.

A key feature of the Gen4 series is its compact design achieved through optimized internal structures. The DELTA 3000 Gen4 is approximately 52% smaller than its predecessor, the DELTA 3 Ultra, while the DELTA 3800 Gen4 is about 44% smaller than the DELTA Pro. The company describes the form factor as being roughly the size of a microwave.

Additional technical specifications include a low standby power consumption of approximately 3W and a specialized “Refrigerator Runtime Boost” mode. The units also support automatic power switching within 10 milliseconds during outages and a “Storm Guard” mode that initiates charging based on weather forecasts. The products will be available for pre-order on October 23, with official sales beginning on October 30, priced at 308,000 yen and 368,000 yen respectively.
