EcoFlow 发布第四代 River 系列便携储能，更小更轻

事件：EcoFlow's new fourth-generation River series. The River 260 Gen4 features a 256Wh capacity battery while the 520 Gen4 packs in 512Wh - storing about 2.5x and 5x the energy of the largest airline-approved power banks, respectively. Better yet, the batteries are built using longer-lasting LFP chemistry that's far less volatile. The River 260 Gen4 features four USB ports, and 300W of max continuous output delivered out its lone AC jack.
