Our take
The Canon Rayo S1 is a highly portable projector for a dark room or short viewing session where battery power and built-in connectivity are more important than a large, bright image. Canon documents native WVGA 854 × 480, 70 lumens standard and 100 maximum without an ANSI label, and up to two hours of battery playback. Android, Wi-Fi, and Bluetooth are listed, but those facts do not guarantee today's app services or phone-mirroring behavior. Verify compatibility and battery health on the exact offer.
A dark-room portable setup where battery operation and a small integrated media device matter more than brightness.
It is not a fit for a bright room, a large detailed image, native HD or Full HD, a confirmed ANSI threshold, or anyone who needs guaranteed current streaming-service support.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Canon documents native 854 × 480 DLP, Wi-Fi, Bluetooth, Android 7.1.2, and 4 GB internal storage.
- The built-in battery is rated for up to about two hours of playback.
- A 3 W mono speaker and compact body can reduce the amount of equipment needed for a short session.
What to weigh up
- The 70-lumen standard figure and 100-lumen maximum are not ANSI-labeled and are low for ambient light.
- WVGA has less detail than 720p and Full HD, particularly for captions and small interface text.
- The model's historic Android version does not guarantee current apps, DRM, or phone-mirroring compatibility.

Full review: how the features affect your choice
What the features mean for you
How much image detail does WVGA provide?
Canon specifies native 854 × 480 DLP resolution, a widescreen WVGA format. It can show basic video and simple images, but it has less detail than 720p or Full HD for subtitles, menus, and presentations. A source may output a higher resolution, yet the projector still displays its native pixel grid after scaling. That matters more as the image gets larger or a viewer sits close. Think of the Rayo S1 as a portable viewing device for modest image size, not as a replacement for a crisp home-cinema projector or a classroom display.
What do Canon's lumen figures mean?
Canon lists 70 lumens in standard mode and 100 lumens maximum, but the specification does not label these numbers ANSI. Preserve that distinction rather than comparing them directly with ANSI-rated projectors. The practical setting is a dark room and a modest projected image; ambient light quickly makes a low-output picture harder to see. The maker's figures describe the model under stated conditions and cannot prove what a used unit produces today. Ask for a current sample image, and test it at the size you expect rather than judging from a product listing photograph.
Will the battery cover the planned session?
Canon states up to two hours of battery playback, which can make the projector easier to carry to a room without a convenient outlet. That is a best-case specification, not a guarantee for an old or heavily used battery. Check whether the unit charges, whether it holds a charge, and whether the correct power adapter is included. A long movie or repeated sessions may need mains power. The battery solves a placement problem; it does not add brightness or detail, so keep the room dark and the screen size conservative.
Are the wireless functions still useful?
Canon's sources list Wi-Fi, Bluetooth, Android 7.1.2, and 4 GB of internal storage. These are real platform facts, but they do not confirm which present-day apps remain available, whether a service accepts the older software, or whether a particular phone can mirror reliably. Treat the integrated system as a feature to verify before purchase, not as an assured substitute for a current streaming device. The reviewed specifications also do not establish a wired HDMI input, so identify a working playback route for the content you plan to watch. Keep a compatible external source as a fallback when possible.
How does the fixed lens affect placement?
Canon gives the Rayo S1 a 1.6:1 projection ratio and fixed optics with manual focus. Without a zoom range, image size is set mainly by the distance to the screen, so measure before placing it on a shelf or travel stand. A digital correction option does not move the lens and may reduce usable image detail. The fixed ratio is conventional rather than ultra-short throw; the projector needs room behind the picture. Align it squarely and confirm focus across the image before assuming the maximum listed diagonal will look clear.
Who should choose the Rayo S1?
Choose the Rayo S1 when a compact battery-powered package and short viewing sessions outweigh low output and WVGA detail. It is less suitable for daylight, a large wall, native HD content, or app-dependent buying decisions that cannot be checked on the exact device. Verify the model code 3481V070, current software behavior, battery runtime, and included accessories; the old model sheet does not establish a present Amazon offer's contents. This assessment uses Canon's model documentation and does not claim hands-on testing, current availability, or that every streaming application works today.
Compare for your needs
For a lower-resolution pocket device with documented HDMI and battery operation, compare Kodak RODPJS75; for native Full HD home viewing, compare Epson Home Cinema 3010.

The decision
The Rayo S1 makes portability and an integrated older Android platform its appeal. Low output, WVGA detail, uncertain app support, and battery condition define its limits.
