EcoFlow RIVER 3 Max Plus Portable Power Station 858Wh 600W Reliable Backup Power for Homes, Caravans and Off-Grid Living

The EcoFlow RIVER 3 Max Plus gives you extra power and longer runtimes in a portable design you can trust day and night.

With 600W of steady output and a surge boost up to 1200W, it keeps your fridge, coffee machine, lights and other small appliances running without interruption.

The built-in UPS takes over in less than 10 milliseconds if the power goes out, so sensitive devices stay protected and keep working smoothly.

This model comes with an 858Wh capacity, ready to power more of what matters most. You can expand the runtime for low-wattage appliances without any cables or complicated setups.

Charging is flexible and simple, with four ways to top up—solar panels, AC wall socket, car outlet or generator.

A full charge takes about 2.3 hours from mains power, and the battery stays in good shape over time thanks to safe, steady charging.

At just 10.8kg and compact enough to fit in a cupboard or vehicle storage, it’s easy to move and pack wherever you need backup.

The long-lasting LiFePO4 battery delivers up to 3000 cycles before it reaches 80% capacity, giving you dependable use for years. 

It also runs quietly under 30 decibels, so you can leave it on all night without any disturbance. For off-grid living, caravan trips or home backup, the RIVER 3 Max Plus offers practical, clean energy that’s always ready.

EcoFlow River 3 Max Plus 600W 858Wh Portable Power Station Reviews

Frequently Asked Questions

How long can the RIVER 3 Max Plus run my devices?

Run times depend on what you’re powering. As an example, it can run a 10W LED light for about 80 hours or a 60W portable fridge for roughly 13 hours before you need to recharge. Higher-wattage appliances will use up the battery faster.

Can I charge the unit while it’s powering appliances?

Yes, the RIVER 3 Max Plus supports pass-through charging. You can keep your devices plugged in and running while the power station itself is charging from mains power, solar panels, your vehicle, or a generator.

Is it safe to leave plugged in for automatic backup?

It’s safe to leave the RIVER 3 Max Plus connected to mains power as a backup. The built-in UPS feature automatically switches over in under 10 milliseconds during a power cut, so your important devices keep running without interruption.
