EcoFlow launches fourth-generation River 260 and 520 portable power stations

EcoFlow has expanded its River line with the fourth‑generation River 260 and River 520 portable power stations, targeting consumers who need compact yet high‑capacity energy solutions. The River 260 Gen4 houses a 256 Wh lithium‑iron‑phosphate (LFP) battery and delivers up to 300 W of continuous power through a single AC outlet, while the larger River 520 Gen4 doubles the capacity to 512 Wh and provides two AC outlets capable of 500 W combined. Both models feature four USB ports and are built with LFP chemistry, which offers longer lifespan and reduced volatility compared with traditional lithium‑ion cells. According to The Verge, the devices can run small appliances such as a portable fridge, power a Starlink Mini satellite terminal, and charge smartphones, delivering roughly 2.5‑ and 5‑times the energy of the largest airline‑approved power banks currently on the market.

The new River stations aim to fill a niche for travelers and remote‑work users who require reliable, airline‑compliant power without the bulk of larger generators. By integrating higher energy density and multiple output options in a lightweight chassis, EcoFlow positions the River 260 Gen4 and River 520 Gen4 as versatile alternatives for on‑the‑go power needs. The launch underscores a broader industry shift toward portable, safe, and high‑capacity battery systems for both consumer and professional applications.
