This EcoFlow RIVER Pro Bundle doubles the capacity of the 720Wh RIVER Pro Portable Power Station with the addition of the 720Wh River Pro Extra Battery to provide 1440Wh of portable power.

No need to live without devices, appliances, or tools when you're away from the grid—the RIVER Pro Portable Power Station from EcoFlow provides 720 watt hours of AC power wherever your adventures take you. The RIVER Pro stores power in a lithium-ion battery that can be charged from AC house current, a vehicle DC outlet, or solar panels. You can use it to charge a typical smartphone 58 times, power a 110W TV for up to 10 hours, or charge a GoPro camera 83 times. Power outputs include two 230V pure sine AC outlets, two USB Type-A ports, one fast charge USB Type-A port, one 100W USB Type-C port, one 12 VDC vehicle cigarette lighter-style socket, and two DC 5521 ports. The battery has an 800-charge life cycle. It recharges in 1.6 hours from an AC source, 6.5 hours from a vehicle DC socket, or 9 hours using two 110W solar panels in full sun. You can double the capacity of the RIVER Pro by connecting an optional extra battery.

Warranty Details


How many times can River Pro charge my DJI Mavic 2 Battery?

10-12 full charges

How many times can River Pro charge my DJI Phantom 4 Pro Battery?

6-8 full charges

Can I control River Pro remotely?

Yes. You can control RIVER Pro using your phone. Just link to it in the EcoFlow app to control it from afar.

Can River Pro handle high-wattage appliances?

Yes. RIVER Pro can power devices up to 1800W with our proprietary technology, X-Boost. *X-Boost can run devices that require up to 1800W, however, it’s best to test before use. Some 600W–1800W appliances with strict voltage requirements may not function (e.g. air compressors).

Can I use solar panels with River Pro?

Yes. You can connect up to 2 sets of 110W solar panels to sustainably charge your RIVER Pro in under 3 hours.

Can River Pro be used as an uninterruptible power supply (UPS)?

It can be an emergency power source (EPS), which will have the same result as UPS for most electronics. Here's the difference. When your RIVER Pro is plugged into the wall, anything plugged into it gets power from the grid, not its battery. If power from the grid stops, RIVER Pro automatically switches to its battery supply mode within 30 milliseconds. That means anything connected will not have power for 30 milliseconds, which may mean sensitive electronics like desktop computers and data servers turn off. Test your devices individually to see if they need UPS to stay powered.

Great Service and Advice as always from Ferntech. — by on 1 October 2021

We've always had great service and advice from Ferntech in store when we've been up to Auckland, and now also online. We haven't used the Ecoflow yet, but have heard good reports about it. We're looking forward to taking it out to charge the drone when camping.
