Our take
The PowerLite S1+ is a small legacy presentation projector whose clearest strengths are its model-specific 1,400-ANSI rating, SVGA image, and documented analog source connections. It weighs about seven pounds and uses a 130 W UHE lamp. The 800 × 600 native panel limits detail, and its roughly 1:1.2 digital zoom does not specify how far the projector must sit from a screen. Choose it only when the older source path and modest image format suit the room.
Basic legacy presentations where compact size and a documented 1,400-ANSI rating matter more than HD or streaming.
It is not for native HD, app streaming, a built-in battery, an established ultra-short-throw installation, or a bright-room promise based on a used lamp.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Epson identifies native 800 × 600 SVGA and a 1,400 ANSI-lumen rating for the S1+.
- The model guide documents VGA, component, S-video, composite, and monitor-out connections.
- At about seven pounds, it is smaller to carry than a full-size fixed-venue projector.
What to weigh up
- SVGA leaves less detail for small slide text and widescreen video than WXGA or Full HD.
- The source set does not establish an optical throw ratio or built-in streaming platform.
- A 130 W lamp and older analog connectors need a current condition and adapter check.

What the features mean for you
SVGA favors basic slides over fine detail
Epson's guide specifies 800 × 600 native pixels for the S1+. That format can handle simple presentations and older computer output, but it gives small type, fine charts, and high-definition video less detail than WXGA or Full HD. A supported signal format is not the same as the physical resolution of the image panel. Decide from the documents and video that the room displays most often. If the main need is to read spreadsheets from the back of a room, a higher-resolution model is a more direct answer than depending on input scaling.
The 1,400 ANSI rating is a useful model comparison
Unlike many old projector listings that repeat unqualified lumen numbers, Epson explicitly rates the S1+ at 1,400 ANSI lumens. That makes the model-level figure comparable in method with other ANSI-labeled projectors. It still does not say how bright an old lamp is today: lamp age, mode, room light, and screen size change the image. Ask for the unit's lamp counter and view the actual picture before relying on the original rating. A light-controlled room and a modest screen are safer assumptions than treating an old lamp as new.
The zoom value is not a screen-distance chart
Epson describes a roughly 1:1.2 digital zoom and manual focus. Digital zoom changes the image framing; it does not establish the optical throw ratio needed to calculate lens distance. Measure the screen and projector position, then confirm the image size on the exact unit. The saved sources do not establish ultra-short-throw placement or optical lens shift. If the room has a fixed mount, compare its location with the manufacturer's placement diagrams rather than assuming that the projector can move close to the wall or shift an image around the mount.
Match the analog inputs to the source
The model guide lists VGA/computer, component video, S-video, composite, and monitor-out connections. Those ports can work in a legacy meeting room, but an HDMI-only laptop or media device may need a converter. The documentation reviewed does not establish an integrated streaming-app system. Identify the exact source and audio plan before choosing the S1+, and confirm that required adapters and cables are available. A monitor output can support a legacy signal chain; it should not be described as wireless presentation or as an onboard media player.
Inspect the lamp and the full input path
Epson specifies a 130 W UHE lamp for the S1+. Remaining lamp life, panel condition, and connector condition depend on the individual unit, so check the lamp timer, focus across the screen, cooling, buttons, remote, and each needed input. The seven-pound body may simplify moving it between rooms, but Epson documents AC operation rather than cordless use. If you need a newer HDMI setup, high native detail, or built-in apps, compare a modern projector instead of purchasing adapters around a system whose core resolution remains SVGA.
What else to compare
Compare the PowerLite S4 for its separate 1,800/1,500 ANSI modes and electronic zoom, or the 915W for WXGA and a stated optical throw range.
Before you buy
What native resolution does the S1+ have?
Epson specifies native 800 × 600 SVGA; accepting an HD signal does not make the panel native HD.
Is its brightness rating ANSI-labeled?
Yes. Epson specifies 1,400 ANSI lumens for this model, though an old unit's lamp condition is unknown.
Does the S1+ have streaming apps or battery power?
The saved Epson sources document analog inputs and AC use, not a built-in app platform or internal battery.

The decision
The S1+ fits a simple legacy presentation path when its compact body and 1,400-ANSI model rating matter more than native HD detail.
