With a removable smart auxiliary battery. Equipped with X-Boost and X-GaNPower technology. Pass-through charging.
A compact mid-range solution with the ability to expand capacity for camping trips and home backup power. Inside, it features a lithium iron phosphate battery with 572 Wh, designed for over 3000 charge-discharge cycles. An interesting feature of the model is support for removable additional batteries, allowing you to flexibly increase the total energy reserve for specific tasks.
The output power is 600W in regular mode, and the X-Boost technology allows devices to draw up to 1200W briefly. The EcoFlow RIVER 3 Max station is equipped with three outlets with pure sine wave, a USB Type-C port at 100W for fast laptop charging, a pair of standard USB-A ports, and a car cigarette lighter. X-GaNPower technology ensures efficient power management, and the pass-through charging feature allows you to simultaneously power connected devices and replenish the station's energy reserves — convenient when working with solar panels. A full charge from a household outlet takes about 90 minutes at 380W, and about 192 minutes from solar panels via XT60. The UPS mode activates in 10 ms, protecting sensitive electronics from voltage fluctuations. Management is available through an app over Wi-Fi or Bluetooth.

Pros
I really like it, beautiful model. Separate battery packs, not very heavy Nothing yet.  kolya Kovalenko: use EcoFlow RIVER 3 Max few months |
Amazing charging station. It saved me during blackouts by charging my laptop. Very good assembly and packaging. The built-in flashlight turned out to be surprisingly useful. It has a UPS function, which is really cool. Charges very quickly. There is an app on the phone. And the main advantage is the ability to add a battery. Did not find it for the entire period.
