The smaller brother of the test winner is a good compromise if you don't need quite as much power and have a slightly smaller budget. Performance such as charging time and runtime are perfectly fine for the basic data.

Product details
The Ecoflow River 2 Max Portable Power Station - EU Version is the improved version of the Ecoflow River Max. This power station is equipped with a LiFePO4 battery. The major advantage of this battery is its six times longer lifespan compared to the previous generation and its numerous charge cycles (over 3,000), which translates to 10 years of daily use. Additionally, the design has been carefully considered; it features a universal, simple design and is 30% lighter than the previous version, weighing in at 6 kg. The first version consisted of two separate components, with the power station equipped with a second battery module. The River Max 2, with its 512 Wh LiFePO4 battery, is more efficient and durable. The positioning of the handle on the back of the power station allows for easy carrying. It achieves optimal charging performance with a smart MPPT algorithm (Maximum Power Point Tracking), which actively detects voltage and current in real-time to reach the maximum power point with an efficiency of over 98%. With a battery capacity of 512 Wh and a power output of up to 500 W (1,000 W peak), this power station is suitable for charging smartphones, tablets, laptops, or lighting and household appliances, such as coolers. Thanks to X-Stream technology, it is possible to fully charge the River 2 Max in just 60 minutes. This way, you won't lose extra time on unexpected outings. Furthermore, the River 2 can also be charged using the included 12V car charger or in combination with solar panels. Through the solar input, up to a maximum of 220 W / 30 V can be connected using the MC4 to XT90 cable. This means that under good weather conditions, the average charging time is only 3 hours.
