The EcoFlow River Max takes the existing EcoFlow River unit and enhances its capacity with an additional removable battery. As a result, you can use the EcoFlow River Max as a single unit at full capacity with 48 Ah of storage, or if you want a lighter leaner experience you can remove the Max battery and utilise it with just the built-in 24Ah battery.

The River Max includes the same great features as the EcoFlow River including the pure sine wave inverter, a huge quantity of outputs you can use simultaneously

The colour LCD screen gives you an easy to see read-out of the battery charge level, devices, connected, critical heat levels, and how long the battery can sustain itself at the current rate of use.

The EcoFlow River Max can be charged in three different ways. AC Input, Car Charger and Solar Panel. The AC charger is designed with X-Strem rapid charging technology meaning the power station can be charged to 80% capacity within an hour, and to full capacity in approximately 1.5 hours. Solar and car charging speeds will differ. The Max has increased AC charging capacity when using the X-Boost fast charge, taking in up to 500w, up from 250w for the EcoFlow River.

EcoFlow camping power stations also include a smartphone app you can use to connect with and control the power station.

No. It is not possible to replace the battery in a portable power station. If you want a product where you have the option to replace the battery then you should consider a battery box. They are similar in many ways and provide you with the capability of changing the battery at any time.

However, given the modular battery system of the EcoFlow River Max product, you could replace your additional battery if you find it to be faulty.

Yes. The EcoFlow River Max has a pure sine wave inverter built in, with dual 240v AC outputs available. It can discharge 600w at any one time, with the potential to discharge up to 1200w for very short bursts using the x-boost technology.

How long does it take to charge?

The EcoFlow River Max has a very fast charging time. Most units can achieve 80% charge within an hour, utilising the X-Boost rapid technology.
