The EcoFlow River 3 Plus provides 286 watt-hours from a LiFePO4 battery and delivers up to 600 watts of continuous power via three standard outlets, with a surge capacity of up to 1,200 watts. This allows you to run a battery-powered speaker for about 2.5 hours or a projector for a good 50 minutes, without a generator or engine noise. With the EB300 or EB600 add-on battery, the capacity can be expanded to 572 or 858 watt-hours; both attach directly without the need for cables.

Prices by rental duration

All prices include VAT, no deposit required, and include all-risk insurance. The first day is the base price; each additional 24-hour day costs an extra €7.47.

How long the battery lasts

Capacity in watt-hours divided by power consumption in watts equals runtime in hours. Because the inverter consumes some energy, about 243 of the 286 watt-hours are actually available to your devices.

Reference values, calculated with approximately 85 percent usable capacity. Volume and ambient temperature significantly affect the results. You can calculate your own requirements using the power consumption calculator.

Where the limit lies

600 watts of continuous power is the hard limit, and three types of devices typically fail here in practice. Fog machines draw many times their continuous power rating when heating up and are the most common mistake. Active subwoofers briefly require more in the bass range than the reserve can handle. And anything with a heating element—such as space heaters, kettles, or coffee machines—exceeds this limit anyway. Short power surges of up to 1,200 watts are covered by the inverter's reserve. For such setups, you need a power station with an output of at least 1,800 watts; you can find a selection in our mobile power supply section.
