Evidence and source details
EcoFlow documents 858Wh combined capacity, 600W ordinary AC output, 220W solar input, one 100W USB-C port and under-10ms UPS transfer. It is an international record, not an Australian-market claim.

Open manufacturer source ↗Is this model right for me?Uses and regional considerations
Low-wattage Australian backup, remote work and travel where compact size beats high AC or solar ceilings.
The 1,200W X-Boost claim is not ordinary inverter output, and this configuration depends on the attached extra battery. Australian bundle contents and execution remain unverified.

- Exact Australian model code with a 230V / 50Hz label and Type I outlets — a shared product name is not shared hardware.
- Australian responsible-supplier and RCM/approval evidence for the exact unit; a travel adaptor is not a regional execution.
- Included AC lead, car lead and solar cable in the Australian bundle — pictured cables are not always included.
- Seller, delivery, warranty territory and consumer-support evidence for Australia before any purchase decision.
No verified Australian-market offering is claimed on this page. A documented manufacturer specification is not proof that the 230V/50Hz Type I Australian model exists, is approved, is stocked or is locally supported.
Australian evidence gateCalculate 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.
