EcoFlow RIVER 2 Pro

Main strength

Offers 768 Wh and 800 W continuous in 7.8 kg: it sacrifices reserve and inverter power compared with the 1 kWh class for lighter transport.

Last documentary review

Official sources reviewed: 2026-10-08. EU, 230 V We have not carried out physical tests.

Who it may suit

An option to investigate for moderate consumption, a vehicle socket and a USB-C laptop of up to 100 W, when energy calculations and simultaneous loads stay within its limits.

When to look elsewhere

For a 1,300 W coffee machine in normal AC mode, or several days exceeding 768 nominal Wh without charging, investigate a larger station. Do not force reduced-voltage mode to justify incompatible electronics.

Main trade-off

The solar input of up to 220 W limits replenishment compared with 500–600 W stations. The vehicle socket and DC5521 ports share a DC budget; X-Boost does not turn its 800 W continuous into 1,600 W continuous.

What we know

Fields with documentation: DC/USB output limits, solar input conditions, nominal capacity, continuous AC power, maximum solar input, weight, dimensions, chemistry, declared cycles, connection features, manufacturer warranty statement, declared peak (duration pending), full mains recharge. Each field retains its limits; this does not verify the whole model.

What needs checking

Your setup still needs checking: startup, cables, ports and simultaneous use, operating conditions and solar installation. The offer, package contents, final price and availability are checked separately.

Next step: check your consumption and appliance connections; nominal capacity alone does not establish compatibility.

How we assess options →
Connections: documented ports, voltages and limits ↓

Documented limits of the reviewed variant. Port power does not guarantee your appliance's protocol, cable or start-up. Shared groups limit the sum of loads.

Charging and power: conditions that change the decision ↓
Mains recharge of the whole battery
70 min (0–100%). This is a manufacturer claim under its stated conditions, not our own measurement. It is not the time to replenish your daily consumption.
Solar input
Solar input 11–50 V, 13 A and 220 W maximum. Panel and MC4-XT60 cable are supplied separately according to the manual; verify Voc below 50 V. Peak sun hours describe equivalent energy, not clock hours at constant maximum power.
Start-up and special modes
Declared peak: 1600 W; duration unverified. Special modes may reduce voltage; they do not replace continuous power.X-Boost: appliance limit of1600W, subject to compatibility.Compatibility limit for certain loads; does not replace 800 W continuous. Check the appliance and its voltage requirements.
Power supply continuity
Transfer verification pending. An EPS/UPS function with interruption does not establish medical continuity or compatibility with all sensitive equipment.

What do watts and watt-hours represent?

The W describe power at a given moment; Whdescribe accumulated energy. Multiplying an appliance's power by its usage hours estimates energy: 100 W for 2 hours is 200 Wh consumed by the appliance. Losses mean the battery must supply more.

  • Phone or tablet: 15 W × 2 h = 30 Wh

    Illustrative load; check charger and USB protocol.

  • Router: 12 W × 8 h = 96 Wh

    Hypothetical constant power; confirm the power supply.

  • LED light: 10 W × 4 h = 40 Wh

    Example of one light; add the others if used simultaneously.

  • Compressor fridge: 45 W × 4 h = 180 Wh

    Four hours of compressor operation, not four clock hours or measured consumption.

Illustrative power and hours, not measurements of your appliances or verified runtime of this station. These Wh represent appliance consumption before losses. Check each appliance's port, voltage, protocol and start-up requirements.

Formulas and assumptions for the AC example ↓

In the example of 100 W for 2 hours, the battery would supply around 265 Wh: AC consumption ÷ 85% efficiency, plus 15 illustrative inverter watts over those two hours.With90% of the768documented nominal Wh available, such a constant load would give approximately5.2 hours. Formula: capacity ×0.9 ÷ (100 ÷ 0.85 + 15).

Battery margin, losses and inverter consumption are planning assumptions, not measurements of this model. Temperature, ageing and variable consumption may change the result. Do not apply this AC example directly to USB or DC.

400 W of panels: generation and solar example ↓

This is nominal generation power. With 4 peak sun hours and 75% assumed solar efficiency, the example is 400 W × 4 PSH × 0.75 = 1200 Wh. This is energy equivalent to six uses of the 100 W, two-hour example before output losses, not six guaranteed uses.

ForEcoFlow RIVER 2 Pro, also applying the documented solar maximum limits the example's power to220W and its indicative calculation to660Wh.Four PSH do not mean four clock hours at a constant 400 W. Voltage, current, connectors, accessories and actual conditions must be checked; clouds or an incompatible input will change the energy. This figure is not a whole-battery recharge time either.

Enter your appliances and days to replace these examples with your own case.

Established fields: DC/USB output limits, solar input conditions, nominal capacity, continuous AC power, maximum solar input, weight, dimensions, chemistry, declared cycles, connection features, manufacturer warranty statement, declared peak (duration pending), full mains recharge. This review does not establish price, stock, ASIN, warranty applicable to your purchase or physical testing.

Specific outstanding checks.

  • Check appliance voltage, connector and start-up; vehicle socket and DC5521 share 126 W.
  • Confirm original EFR620 version: do not apply these figures to RIVER 2 Pro 700 or a revision with different ports.
