FlashFish E112B vs EcoFlow RIVER 2 Pro for Selected Loads

Short answer: choose FlashFish E112B when your declared load set benefits from its documented 1200W shared continuous AC output and 1008Wh nominal energy, and an 11.2kg station fits the carry plan. Choose EcoFlow RIVER 2 Pro when its lower documented mass, 800W continuous envelope, app controls and explicitly documented chemistry or peak behaviour matter more. Neither is the universal winner.

This is a manufacturer-document comparison, not a laboratory test. E112B's authoritative local record does not supply chemistry, AC output frequency, peak output, UPS/EPS, app control or warranty. Those unknowns must remain visible. RIVER 2 Pro features documented by EcoFlow cannot be transferred to E112B.

Next step: check E112B against your exact appliance labels. Treat the table as a shortlist tool, not permission to connect an unverified load.

Use an appliance envelope before comparing feature lists

Write down every simultaneous load, its regional voltage/frequency requirement and maximum or startup demand. A 900W heating appliance and a 900W motor load do not create the same evidence question. Heating may be steady; a compressor or pump can demand more at startup. If the manufacturer does not supply the needed startup figure, a continuous rating alone cannot settle the pairing.

Then define session energy. Nominal Wh can rank stored-energy scale, but it is not delivered AC energy and it does not predict runtime without load, conversion loss, temperature, battery condition and control behaviour. A larger Wh figure is useful only when the extra energy answers a real session requirement.

Where E112B fits better on paper

• A verified steady AC load is above 800W but no more than 1200W, and startup demand is known.
• The plan needs more nominal stored energy and accepts the heavier station.
• Two AC sockets help organise compatible loads while their total remains inside the shared 1200W ceiling.
• A compatible DC charging source can use the documented 10.5-60V, up-to-600W input envelope.

These are document-fit statements. They do not establish a runtime, charging time, appliance result or value-for-money advantage. E112B's two sockets do not create 1200W per socket.

Where RIVER 2 Pro may fit better

• A 7.8kg station is materially easier for the intended carry route than an 11.2kg station.
• The load set fits the normal documented 800W continuous AC envelope.
• 100W USB-C input/output or app monitoring is a required feature.
• The buyer needs manufacturer-documented LFP chemistry, 1600W peak wording or specified app connectivity before shortlisting.

EcoFlow's page describes X-Boost up to 1600W, but that is not the same as normal 1600W continuous output. Check the appliance and exact mode guidance. The feature is also not evidence that every high-wattage appliance operates normally.

Three buyer profiles

1. A verified 900W resistive appliance

If the exact European appliance label shows 900W steady demand and no unresolved startup requirement, E112B clears the first continuous-rating screen; RIVER 2 Pro's normal 800W AC rating does not. That is a reason to test E112B, not a compatibility certificate. Do not replace this screen with RIVER 2 Pro X-Boost marketing or an undocumented E112B peak figure.

2. A 600W mixed camping kit carried from the car

Both products may clear the continuous watt screen, subject to simultaneous-load and port checks. RIVER 2 Pro is about 3.4kg lighter by the cited station-only figures; E112B lists 240Wh more nominal energy. The decision turns on the walking route, required session energy, output paths and recharge opportunity—not one headline ratio.

3. A buyer who requires app control or proven chemistry evidence

EcoFlow documents Wi-Fi/Bluetooth app control and LFP chemistry for RIVER 2 Pro. The authoritative E112B record selected for this article does not establish equivalent features. A required feature must be supported, so E112B should not be chosen on the assumption that a public-page phrase or related model fills the gap.

Charging evidence needs its own boundary

E112B's authoritative record lists AC input up to 960W and DC input up to 600W. Input ceilings are not promised charge rates or proof that both paths can be combined. RIVER 2 Pro's manual lists 220-240V AC input up to 8A, solar up to 220W and USB-C input up to 100W. Its current product page shows inconsistent 870W and 940W AC-input/recharge wording. For that reason, this comparison does not name a charging-speed winner or repeat a headline time.

Before purchase, verify the exact delivered regional unit, included cables, source voltage/current range and whether the planned charging paths are allowed. A fast wall headline is irrelevant if the intended trip depends on a different source.

When neither product is the right recommendation

• The essential appliance exceeds the documented continuous envelope or has unknown startup demand.
• The use case requires building-wide backup, medical assurance or a certified electrical installation.
• A mandatory feature is undocumented for the chosen model.
• The carry route, placement or ventilation cannot safely accommodate the full kit.
• The buying decision depends on an unverified price, stock level, warranty interpretation or promised runtime.

Frequently asked questions

Is FlashFish E112B an EcoFlow RIVER 2 Pro alternative?

It can be an alternative for buyers who need up to 1200W documented continuous AC output and 1008Wh nominal energy, provided the exact appliances and carry plan fit. It is not a feature-for-feature substitute because several E112B fields remain undocumented in the authoritative local record.

Which station is easier to carry?

The cited records list about 7.8kg for RIVER 2 Pro and 11.2kg for E112B. Whole-kit weight, handles, route and user capability still need a practical check.

Can E112B run appliances above 800W?

Its documented continuous AC ceiling is 1200W, so an exact steady load between 801W and 1200W may clear the first label screen. Startup demand, regional requirements and every simultaneous load still have to be verified.

Does RIVER 2 Pro X-Boost equal normal 1600W output?

No. EcoFlow documents normal AC output at 800W and separately describes 1600W surge or X-Boost behaviour. Treat manufacturer-specific modes separately from continuous output and check appliance suitability.

Which product has faster charging?

This article does not declare a charging-speed winner. Input ceilings and charge curves are different evidence, and EcoFlow's current page contains inconsistent AC-input figures. Verify the exact regional manuals and measured conditions.

Before purchase: ask FlashFish support about undocumented E112B features. If an answer is essential, obtain it in model- and region-specific form before choosing.

Sources and evidence limits

Checked 8 October 2026. E112B values come from the authoritative FlashFish EU manual-derived local record; the Europe page and fresh Admin evidence establish an active public route. RIVER 2 Pro values come from EcoFlow's Europe page and model EFR620 manual. Both are manufacturer sources. FlashFish publishes this comparison and sells E112B. No shared physical test, runtime, efficiency, noise, durability, reliability or value assessment was performed. The Shopify-owned image shows E112B only and is not competitor test evidence.
