Product Overview

The River 3 Max Plus Portable Power Station powers small electronics and low-wattage essentials for outdoor and indoor use.

Compact dimensions and a weight of 10.8kg make it easy to store in tight spaces or transport in a car boot, camper or bag. The LiFePO4 battery cells support reliable backup for phones, lights and networking gear, while the gallium nitride based power management extends runtime for lighter loads. Quiet operation is suitable for bedrooms, studies or overnight use where fan noise can be a drawback.

Charging flexibility is provided by four options, allowing you to top up at home, in the car or off-grid depending on your setup. The station reaches a full charge in one hour and can be controlled via the EcoFlow App. Its waterproof, fireproof and drop-resistant design adds durability for outdoor routines.

Model EFRIVER3MAXS in grey comes with a 5 year manufacturer's warranty.

Things to consider

With a 600W AC output, it is better for small electronics and low-wattage essentials than for running larger appliances or heavier workshop equipment.

Camping suitability

9/10 - compact, quiet and easy to recharge in multiple ways, making it well suited to camping and road trips.

Emergency backup fit

8/10 - a strong option for phones, lights and routers during outages, but not intended for higher-wattage household appliances.

Portability rating

8/10 - portable at 10.8kg with compact dimensions, though not as light as smaller entry-level units.

Multi-device compatibility

Suitable for phones, tablets, lights, networking gear and other small electronics using AC, USB-A and USB-C connections.

Battery endurance rating

8/10 - the 858Wh battery offers useful runtime for small essentials, especially lighter loads, but capacity is still limited for larger devices.

Key benefits

  • 600W AC Output: Powers everyday essentials such as phones, lights, networking gear and other low-wattage devices.
  • 858Wh LiFePO4 Battery: Provides dependable portable backup capacity with battery chemistry known for strong durability and stability.
  • 1-Hour Full Recharge: Gets back to full power quickly when you need a fast turnaround between trips or outages.
  • Four Charging Options: Lets you recharge at home, in the car or off-grid to suit different travel and backup setups.
  • Quiet Operation: More suitable for bedrooms, studies and overnight use where fan noise can be disruptive.
  • Compact 10.8kg Design: Easier to store in tight spaces and simpler to transport in a car boot, camper or bag.
  • App Control: Makes it easier to monitor and manage the power station from your phone.
  • Durable Housing: Waterproof, fireproof and drop-resistant construction adds confidence for regular outdoor and travel use.

Q: Can this power station run a household refrigerator?

A: No. EcoFlow River 3 Max Plus has a 600W AC output, which suits lighter essentials like lights, phones and networking gear. A household refrigerator usually needs a higher startup load, so this model is not the right pick for fridge backup.

Q: Will the USB-C ports charge a laptop properly?

A: Not necessarily. EcoFlow River 3 Max Plus has 2x USB-C and 2x USB-A ports, but its USB charging wattage is not specified for this model. It is a safer fit for phones and tablets than laptops that may require higher USB-C power.

Q: Is a solar panel included in the box?

A: No. EcoFlow River 3 Max Plus includes an AC charging cable, car charging cable and a USB-B to USB-A UPS communication cable. A solar panel is not included, so solar charging requires a separate compatible panel.

Q: Can I use it overnight in a bedroom?

A: Yes. EcoFlow River 3 Max Plus is designed for quiet operation, which suits bedroom or study use where fan noise can be distracting. Its 600W output still limits it to lighter devices rather than heaters or other high-draw appliances.

Q: What devices suit the EcoFlow River 3 Max Plus best?

A: EcoFlow River 3 Max Plus is best matched to small electronics and low-wattage essentials such as phones, lights and networking gear. Its 858Wh battery is useful for longer runtimes with lighter loads, but the 600W output limits larger appliances.

Q: Can it be recharged in a car or off-grid?

A: Yes. EcoFlow River 3 Max Plus supports four charging options, so it can be topped up at home, in the car or off-grid. A full recharge takes one hour, which is handy before leaving home or between shorter backup jobs.
