EcoFlow RIVER 3 Max Plus Wireless Power Station · 858 Wh / 600 W

Compact power, with a longer working window. RIVER 3 Max Plus Wireless combines the RIVER 3 Plus platform with an EB600 extra battery for 858 Wh of total energy. It is well suited to selected manicure desk equipment, lighting and everyday electronics, with the convenience of Qi2 wireless charging for a compatible phone.

The complete 858 Wh configuration

• 858 Wh combined LFP capacity; 600 W continuous AC output.
• Three EU AC outlets, USB-A and USB-C charging.
• Wireless charging up to 15 W for compatible Qi2 devices.
• Solar input up to 220 W and EcoFlow app monitoring.

What could it power in your studio?

These are calculated examples, not manufacturer runtime guarantees: battery capacity × 75–85% ÷ continuous average load. A 200 W desk example combines a 40 W e-file, 100 W dust collector, 48 W curing lamp and 12 W task light. Your equipment may use different power, and lamps and drills often run intermittently. Battery age, temperature, inverter consumption and charging behaviour change the result. Check actual wattages and starting surges. The continuous output limit applies to all connected equipment together.

What can be added?

The EB600 expansion is already part of this 858 Wh configuration. This is the maximum battery capacity of the RIVER 3 Plus system: it does not accept a second expansion battery on top. Compared with the 286 Wh base station, it provides three times the nominal energy. Its continuous AC output remains 600 W.

Connect suitable appliances directly to the station. Capacity in Wh determines how long it can run; output in W determines what it can run at once. An extra battery increases runtime, not AC output. Do not treat X-Boost figures as the continuous output rating. Automatic backup switching has a brief transfer time; check that connected equipment tolerates it.
