Evidence and source details
EcoFlow lists 858Wh combined capacity, 600W ordinary AC output, 220W solar input, a 100W USB-C port and under-10ms UPS transfer. The cited source is a regional specification for the Philippines; it does not prove the 120V / 60Hz Canadian version.

Open manufacturer source ↗Is this model right for me?Uses and regional considerations
Canadian low-wattage backup, remote work and travel where compact size matters more than high AC or solar ceilings.
The 1,200W X-Boost figure is not ordinary 1,200W inverter output, and this configuration depends on the attached extra battery. Confirm which regional bundle is offered in Canada before comparing packages.

Calculate runtimeQuestions about this model
How much energy does the RIVER 3 Max Plus store?
The manufacturer lists 858 Wh. Conversion loss and a reserve reduce the energy available to your devices.
How much power can it deliver?
Normal continuous output is 600 W. A short surge figure does not prove that every motor or appliance can start.
Which solar panel can I use?
The documented input range is 11–55 V, up to 220 W total. Also check current, cold open-circuit voltage, connector and polarity.
Still comparing?
Compare capacity, output and the exact regional version.
