EcoFlow Technology Japan has announced that it launched its new “DELTA 3 2000 Air” portable power station. Positioned in the 2kWh class, the new unit combines 1,920Wh of storage capacity with a lightweight design aimed at improving portability for household backup power, vehicle use and outdoor applications. The company simultaneously released a 220W lightweight bifacial solar panel using TOPCon cells, presenting the products as a combined solution for improving energy self-sufficiency during outages and off-grid use.

Despite its relatively compact dimensions of 220 × 223 × 426 mm, the DELTA 3 2000 Air offers rated output of 1,000W with 1,500W surge capacity and dual AC outlets. EcoFlow says the unit can support essential appliances such as refrigerators, lighting, notebook PCs and communications equipment during blackouts. The product uses lithium iron phosphate batteries and is rated for about 3,000 charge-discharge cycles while retaining 70% capacity, underscoring its positioning as a long-life backup power device rather than a short-term consumer gadget.

The company also highlighted disaster-preparedness and business continuity planning (BCP) applications, noting that the system can be used for communications backup, temporary server protection and auxiliary power for medical devices in homes and small offices. Its flat handle and compact form factor are intended to make storage easier in limited spaces such as under car seats or in narrow household gaps. The newly launched 220W bifacial solar panel, weighing approximately 5.1 kg, is designed to complement the power station by enabling more autonomous power supply in disaster or outdoor settings.

Koshin plans to release its new “Hybrid Power Storage System” Feb. 24, 2026, to counter power outages. The system combines a portable power station (BPS-24LD) and an inverter generator (GV-18iSD). Simply connecting the two with a dedicated cable enables the system to automatically cycle between generating and storing electricity.

Unlike a standalone portable power station, which becomes unusable once its battery runs out, or a standalone generator, which is difficult to use at night or in residential areas due to its outdoor nature, this hybrid system can store electricity generated by the generator in the portable power station. This enables quiet indoor use as needed. When the portable power source’s charge falls below a certain level, the generator automatically starts and shuts off once the unit is fully charged. This feature provides a long-term power supply without the need for cumbersome operation and supports household appliances such as refrigerators and heating equipment. The system also features a CO sensor and a safety function that automatically stops the generator during improper use. This system is expected to enhance household peace of mind in preparation for prolonged power outages caused by an increase in natural disasters in Japan.
