RIVER Series

The RIVER series is EcoFlow’s budget-friendly portable power station lineup. Despite its affordable price, the RIVER series offers all the essential functions and performance needed from a portable power station, making it a popular choice for entry-level users.

EcoFlow also offers the higher-end DELTA series for more demanding applications, but the RIVER series keeps many of the same features while reducing battery capacity, maximum output, and the number of input/output ports to keep the price low.

Benefits of the RIVER Series

Entry-Level Models Starting at Under 20,000 Yen — Perfect for First-Time Buyers

The biggest advantage of the RIVER series is its price. While many portable power stations fall in the 50,000 yen range, the RIVER 2 series entry-level models can be purchased for under 20,000 yen with discount coupons.

This makes it an ideal option for first-time buyers looking to try a portable power station without spending too much. It’s also great for experienced users who want a compact secondary unit for light use.

Affordable Yet Fully Equipped with Features and Performance

In the portable power station market, lower-priced models often come with compromises — such as using older battery technology, lower input/output performance, fewer ports, or limited display information.

However, the RIVER series delivers the same key features and performance as EcoFlow’s higher-end models, even at a lower price point. It uses LiFePO4 (LFP) batteries, offers a maximum output of over 300W, includes all essential input/output ports, and supports app-based management.

Aside from its smaller battery capacity and lower output compared to higher-end models, the user experience and functionality are virtually the same.

Drawbacks of the RIVER Series

Limited Battery Capacity

The main drawback of the RIVER series is its small battery capacity. While a smaller battery makes the unit more compact and lightweight, it also limits operating time.

With shorter usable hours, you’ll need to recharge more frequently, increasing the battery cycle count. For heavy-use scenarios — such as powering heating or cooling devices — this could be a significant limitation, so careful consideration is necessary if you need long-lasting power.
