Short answer: if the equipment genuinely requires a documented direct 12V source, E112B is the relevant candidate in this two-model comparison. It declares a shared 12V/10A/120W group across two DC5521 outputs and the car output, while EcoFlow's EU specification for DELTA 3 Classic states that it has no 12V DC output. That narrows the shortlist; it does not prove E112B compatibility.
The deciding evidence is the output path, not the nearly equal nominal battery figures. Before choosing, obtain the equipment's exact voltage, connector dimensions, polarity, current and operating pattern. Do not bridge a missing port with an improvised adapter or turn this narrow result into an overall performance verdict.
Quick comparison for a direct 12V kit
| Decision field | FlashFish E112B | EcoFlow DELTA 3 Classic | What it means |
|---|---|---|---|
| Direct 12V output | 12V, 10A, 120W shared across DC5521 x2 and car output | Official EU specification: no 12V DC output | If direct 12V is mandatory, only E112B documents that route in this pair |
| Nominal energy | 1008Wh | 1024Wh | Neither figure proves delivered energy or runtime |
| Declared weight | Approximately 11.2kg | 12.1kg plus or minus 0.3kg | Useful for transport planning, not electrical fit |
| Unresolved before use | Connector, polarity, device current and shared-load total | Required direct 12V route is absent | Do not proceed without a documented complete path |
Review E112B's documented output routes and compare them with the exact device manual. The product page is a specification source, not a compatibility certificate for unnamed equipment.
Why the port comes before capacity
A 12V device cannot use nominal watt-hours unless there is a supported electrical route between the station and the load. EcoFlow's DELTA 3 Classic EU specification explicitly lists no 12V DC output. That is a decisive non-fit for a brief that requires a native direct 12V output; it is not criticism of the model's AC or USB uses.
E112B's direct-DC group is documented, but shared limits matter. Two DC5521 sockets and the car output draw from one 12V/10A/120W group. The current of simultaneous devices must be considered together, and the connectors still have to match in size and polarity. A plug that fits physically is not enough.
Five checks for the exact equipment kit
- Voltage: confirm the device is designed for the station's documented 12V output range; do not assume every product marketed as '12V' has identical tolerances.
- Connector: record the connector family and dimensions from the device manual, not from appearance.
- Polarity: confirm centre-positive, centre-negative or another arrangement from the manufacturer.
- Current and power: compare the device's maximum demand with the shared 10A/120W group and include every simultaneous DC load.
- Operation: note startup behaviour, duty cycle, cable condition and any manufacturer restriction, then run one supervised full-use rehearsal before relying on the setup.
Where E112B may fit
E112B may fit when the equipment manual confirms a 12V path compatible with one of its documented outputs, polarity and connector dimensions match, and the complete DC group remains inside the shared 10A/120W ceiling. Its 1008Wh nominal energy can then inform later runtime planning, but only after conversion losses, actual load and reserve are considered.
Where DELTA 3 Classic may still fit
DELTA 3 Classic may suit a different brief built around its documented AC or USB outputs. This article does not score those routes because the selected use case specifically requires direct 12V. Changing the load path changes the comparison and requires a new review of the exact equipment.
What is deliberately excluded
- No adapter or cable workaround for an absent output.
- No AC-output headroom verdict; E112B's 1200W is a shared maximum, and its continuous and peak AC ratings are unprovided in the authoritative record.
- No price or stock comparison; the competitor page currently contains mixed sale and sold-out presentation.
- No claims about runtime, conversion efficiency, reliability, noise, charging speed or a universal winner.
- No use of inconsistent competitor USB-A or outlet-count rows.
Frequently asked questions
Which station has a documented direct 12V output?
E112B documents a shared 12V/10A/120W group across two DC5521 outputs and the car output. The DELTA 3 Classic EU specification says it has no 12V DC output.
Does that make E112B compatible with every 12V device?
No. The exact device must match voltage, connector dimensions, polarity and current requirements, and all simultaneous DC loads must stay within the shared group limit.
Which model has more battery capacity?
The declared nominal figures are 1008Wh for E112B and 1024Wh for DELTA 3 Classic. The small nominal difference does not decide connector fit, delivered energy or runtime.
Can an adapter add a direct 12V output to DELTA 3 Classic?
No adapter workaround is evaluated or recommended here. If a required output is absent from the exact manual, choose a documented route or obtain manufacturer guidance for the complete system.
Which station is the better overall purchase?
This comparison does not establish an overall winner. It answers one narrow question: whether the exact station documents the required direct 12V path.
Conclusion
For a kit that truly requires direct 12V, E112B stays on the shortlist because it documents that output group; DELTA 3 Classic does not. The next step is evidence, not improvisation: match the exact device voltage, connector, polarity and current, then rehearse the complete setup. Ask FlashFish Europe to check your exact 12V equipment path if any field remains unclear.
Sources and method
Checked 21 October 2026. FlashFish product data and the current Europe route supply E112B facts; EcoFlow's exact EU page supplies DELTA 3 Classic facts. This is a manufacturer-declared route comparison, not a side-by-side test. No runtime, efficiency, price, stock or reliability conclusion is made.
