EcoFlow 让迷你移动电源变得更小巧
More energy packed into far less space makes these batteries ideal for day trips or weekend getaways. 在更小的空间内塞入更多能量，使得这些电池成为短途旅行或周末出游的理想选择。
If you’re in the market for a tiny power station that punches well above its size and weight then have a look at EcoFlow’s new fourth-generation River series. 如果你正在寻找一款“小身材、大能量”的迷你移动电源，那么不妨看看 EcoFlow 新推出的第四代 River 系列。
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. The River 500 Gen4 features the same USB port selection but offers a pair of AC jacks good for 500W of continuous output. River 260 Gen4 配备了 256Wh 容量的电池，而 520 Gen4 则拥有 512Wh 的容量——其储能分别约为目前市面上最大容量航空合规充电宝的 2.5 倍和 5 倍。更棒的是，这些电池采用了寿命更长、稳定性更高的磷酸铁锂（LFP）化学材料。River 260 Gen4 配备了四个 USB 接口，并通过唯一的交流（AC）插口提供 300W 的最大持续输出功率。River 520 Gen4 拥有相同的 USB 接口配置，但提供了两个交流插口，支持 500W 的持续输出。
Both of EcoFlow’s Gen4 power stations feature class-leading energy density that cuts both the weight and size, making these power stations lighter and more compact than similarly-specced competition. That makes them ideal for an overnight camping trip or photo shoot in the literal field. The EcoFlow 520 Gen4 is powerful enough to keep a standard US fridge running for about 4 hours during a blackout. EcoFlow 的这两款第四代移动电源均具备行业领先的能量密度，在减轻重量的同时缩小了体积，使其比同规格的竞争产品更轻便、更紧凑。这使得它们非常适合过夜露营或户外摄影。EcoFlow 520 Gen4 的电量足以在停电期间维持一台标准美式冰箱运行约 4 小时。

Both models can serve as a UPS for your computer, with a cutover time of less than 10ms, and feature one state-of-the-art 140W USB-C PD3.1 port that’s bidirectional. That little trick lets these power stations eschew charging bricks in favor of direct DC charging from a 140W USB-C wall charger you might already own, or a portable USB-C solar panel EcoFlow will happily sell you. 这两款机型均可作为电脑的 UPS（不间断电源）使用，切换时间小于 10 毫秒。它们还配备了一个先进的 140W 双向 USB-C PD3.1 接口。这一巧妙设计让用户无需携带笨重的充电砖，只需使用你现有的 140W USB-C 墙插充电器，或者 EcoFlow 提供的便携式 USB-C 太阳能板，即可直接进行直流充电。
EcoFlow has also addressed a common problem with all power stations that causes them to eventually die if left idling too long. By minimizing the energy spent converting stored DC to AC output, more watt-hours remain to charge your drone, bike computer, and phone, or to power your Starlink Mini and compact fridge. EcoFlow 还解决了一个所有移动电源的通病：长期闲置导致的电量损耗。通过最大限度地减少直流转交流过程中的能量损耗，更多的电量得以保留，用于为你的无人机、码表、手机充电，或为 Starlink Mini 和小型冰箱供电。
The River 260 Gen4 will be available in Europe from Q4 2026, while the River 520 Gen4 will follow sometimes in Q1 2027. Pricing for both will be announced as we get closer to their global release dates. River 260 Gen4 将于 2026 年第四季度在欧洲上市，而 River 520 Gen4 则计划于 2027 年第一季度推出。两款产品的具体售价将在全球发布日期临近时公布。
