Our take
The S4 identity is verified, but the available manufacturer evidence supports a narrow recommendation. WiMiUS's correction table names the S4 and replaces an earlier 8,000-lux advertisement with a 250–280 ANSI-lumen range. That correction is useful because the ANSI label supplies a clear measurement basis, but it does not resolve which S4 hardware revision appears in the historical candidate row. The checked source does not verify native resolution, throw, connections, wireless behavior, or battery operation. Treat this as a low-confidence fit until the exact unit's manual or label is matched to a complete specification.
A buyer willing to investigate an exact used S4 revision before relying on its limited verified specification.
It is not for a hard Full HD, close-wall, battery, streaming-app, or high-brightness requirement when the candidate revision and those specifications are still unverified.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- WiMiUS itself publishes an S4-specific correction rather than leaving the 8,000-lux value in place.
- The corrected 250–280 ANSI-lumen range has an explicit ANSI basis.
- The exact model identity can be searched without pretending the old ASIN is current offer proof.
What to weigh up
- The saved source does not map the historical candidate to a specific S4 hardware generation.
- Native pixel count and projection geometry are not established for that revision.
- Inputs, streaming, battery operation, and current unit condition remain unknown.

What the features mean for you
What is actually verified about this S4?
The manufacturer correction page names the WiMiUS S4 and gives one confirmed specification change. It does not connect the frozen candidate's exact revision or listing package to a full S4 manual. That distinction matters because similarly named projector revisions can use different panels, optics, ports, or wireless boards. The model can be treated as a verified projector identity, but its intended role cannot be assigned confidently from this source alone. A buyer should compare the unit label and serial information with a revision-specific manufacturer document before using it as a replacement for a known home or presentation model.
How should the corrected ANSI range be read?
WiMiUS's table replaces an earlier 8,000-lux advertisement with a range of 250–280 ANSI lumens for the S4. The profile records 250 as the conservative floor of that published range, not as a single exact output, and the full range remains visible in the article. ANSI labeling makes the correction more interpretable than the prior lux number, but the notice does not provide a measurement for an individual used projector. A low-end brightness requirement, a large screen, and ambient room light still need careful judgment. Do not carry forward the superseded 8,000-lux claim.
Can resolution be used to choose a screen size?
The correction notice does not state native panel pixels or an exact hardware generation. Without those facts, a buyer cannot reliably compare image detail with native 720p, WXGA, or Full HD models, and an input compatibility claim would not substitute for a native pixel specification. Keep native horizontal pixels unknown instead of copying a historical listing title. If fine text, subtitles, or a large screen matter, ask for the exact manual and verify the unit's hardware label before choosing. A measured source-backed resolution would materially change whether this projector belongs on a particular shortlist.
What remains unknown about placement and connections?
No source in this check verifies the S4 throw ratio, zoom, focus range, keystone controls, input panel, battery, or built-in streaming apps for the historical revision. Those unknowns affect basic fit: the projector may not reach the desired screen size from the available shelf, and its connectors may not match a laptop or media player. Measure the intended room only after locating a revision-specific setup guide. Confirm that any claimed wireless feature is distinct from an app platform, and do not infer a battery from outdoor-use wording or a compact cabinet.
When is it reasonable to keep investigating?
The S4 may merit further research when its model name and corrected ANSI range match what a seller offers, and the buyer can delay a decision until the revision is established. Ask for clear photographs of the chassis label, model suffix, input panel, and system information screen, then compare them with a WiMiUS manual for that revision. Check startup, focus, dust, fan, remote, power supply, and the projected image on the actual unit. The tagged search URL is only a route to offers; it does not verify an ASIN or package. If the seller cannot establish the revision, choose a model with a complete source-backed profile instead.
What else to compare
For a source-verified meeting projector with native WXGA and 3,000 ANSI lumens, compare Hitachi CP-WX3015WN; for a documented Full HD home model, compare BenQ HT1070A.
Before you buy
What brightness does WiMiUS correct the S4 to?
The official notice replaces the earlier 8,000-lux figure with a range of 250–280 ANSI lumens.
Is the S4 candidate's native resolution known?
No. The checked correction notice does not identify native pixels or map the historical candidate to a specific S4 revision.
Can its throw distance or inputs be confirmed?
Not from the checked source. Find a revision-specific manual and compare it with the exact unit before planning the room.
