Ecoflow River Max Mobile Power Station

Key Features of the Ecoflow River

  • Thanks to its smart X-Stream integrated inverter, the River can charge from 0% to 80% in only 1 hour. You can switch to a quieter charging condition by turning on the “Quiet Charging” status on the Ecoflow app.

  • The extra battery doubles the capacity from 288Wh to 576Wh for when you need more power, you can also detach the extra battery easily for more portability.

  • With two AC outlets and a wide range of USB ports, you can charge up to 9 devices simultaneously.

  • The River Ecoflow features a pure sine wave 600W output, and can power devices up to 1800W with X-Boost enabled. Use devices below 1200W for the best product use.

The Modular Ecoflow River Max UK

Invented with versatility in mind, the modular design of the Ecoflow lets you choose between capacity and portability on the spot. Attach the Extra Battery to double your capacity from 288Wh to 576Wh, or leave it detached to lighten your load by 5.5 pounds.

Whichever you choose, even with one lithium-ion battery the River mobile power station outputs 600W of continuous power. With X-Boost on, this compact package can easily power devices up to 1800W, such as your fridge, kettle, or coffee maker.

Charging the Ecoflow River Max

The record-breaking speed of charging the Ecoflow River Max is possible by using truly cutting-edge technology. Because the River mobile power station was designed to be used on the go, it goes without saying that you can charge it in many different ways. You can fully charge it from an AC source, like the grid or a generator, in under an hour and a half.

If you’re outdoors and don’t have access to an AC power source, Ecoflow has you covered. You can power the River from your car in a mere 3 hours. Or you can opt for two small, 110 Watt solar panels, and charge the Ecoflow River portable power station in approximately 2 hours. Its versatility is truly unmatched.

EcoFlow X-Stream Recharging

EcoFlow’s X-Stream technology reinvents the charging process of portable power stations. With an integrated smart inverter, it eliminates the need for bulky adapters, and speeds up the charging process nearly tenfold! This allows the Ecoflow River portable power station to fully recharge in a mere 1.6 hours – faster than any other portable power station on the market.

Ecoflow X-Boost Smart Algorithm

With the help of the X-Boost mode, the Ecoflow Delta generator can power devices that exceed its 600W continuous power limit. X-Boost lowers the Voltage and the Amperage, allowing you to power high-wattage devices at a lower wattage. It is recommended that you leave X-Boost on all the time, as it generally improves performance, and lets you reliably power devices up to 1800W.

Clean and Comfortable Display

The Ecoflow Delta features a sharp and bright LCD display. On it, you can find information about the charging time, time-to-full-charge, run time, as well as a timer. It also allows you to easily navigate and use the various features of the Delta.

Benefits of the River

  • Lightning-fast charging means that you can have an uninterrupted power supply anywhere you go.

  • Its sleek, compact, and lightweight design means that you can confidently take the EcoFlow River with you anywhere you go.

  • A wide range of various ports means that the River is compatible with practically all household devices.

  • Faster charging means that you have less downtime, and more time powering your devices.
