Our take
GPX's PJ308W is a compact external-source projector built around a native 800 × 480 image and a useful spread of connectors: two HDMI inputs, VGA, USB, microSD, and AV. That can simplify switching among older and newer sources, while the native panel remains low resolution for fine text or detailed movies. GPX lists 2,000 lumens without an ANSI basis. Its page also distinguishes revisions 1993 and 2190, with Bluetooth audio transmission only on the latter; the saved candidate does not identify which revision it is. Treat revision-specific Bluetooth as unknown.
A compact external-source setup where HDMI or removable-media connections matter more than native detail, ANSI-rated brightness, or confirmed Bluetooth.
It is not a high-detail home-theater projector, a model with a verified ANSI rating, or a confirmed battery-powered choice for use away from an outlet.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Two HDMI ports plus VGA and AV accept a mix of newer and older external sources.
- USB and microSD add local-media options beyond a single HDMI device.
- The compact format and manual focus provide a straightforward small-projector setup.
What to weigh up
- Native 800 × 480 resolution limits text clarity and detail compared with HD projectors.
- GPX's 2,000-lumen figure is not labeled ANSI and should not be compared as standardized output.
- The historical candidate does not identify the 1993 or 2190 revision, so Bluetooth capability and battery behavior remain unresolved.

What the features mean for you
The port list is more flexible than the panel is detailed
GPX documents two HDMI inputs, VGA, USB, microSD, and AV on the PJ308W. That mix can work with a streaming stick, laptop, older composite source, or supported files on removable media without requiring one particular connection. It does not change the projector's native 800 × 480 pixel grid. Small interface text and detailed film scenes will look softer than on a native HD model, so consider the normal viewing distance and screen size before treating the connector count as a home-cinema advantage.
Do not confuse input support with native resolution
The manufacturer page gives 800 × 480 as the native resolution. A source may send a larger signal through HDMI, but the projector must scale that signal to its own panel. For slides with large lettering or casual video on a modest image, that compromise may be manageable; spreadsheets, subtitles, and close viewing reveal the limit sooner. GPX's 2,000-lumen claim has no ANSI label on the checked page, so it cannot be compared directly to products whose manufacturers state ANSI lumens.
The revision changes the Bluetooth story
GPX says version 1993 lacks Bluetooth and version 2190 adds a Bluetooth audio transmitter. The frozen candidate does not tie its identity to either revision. A buyer who depends on wireless sound should read the unit label and seller's photographs carefully rather than assuming every PJ308W has the later audio feature. Even on the 2190, the page describes audio transmission, not wireless video mirroring. Plan for an HDMI or other listed source connection and confirm how audio will reach the intended speaker.
Manual setup keeps placement flexible but not automatic
GPX lists manual focus and keystone correction, not autofocus or an optical zoom range. The reviewed product page does not establish a throw ratio, battery runtime, or a rechargeable battery. It describes AC/DC adapter power; that is not evidence that the projector can run unplugged. Arrange access to its specified power supply and test focus at the planned image size. If the room demands close-wall placement, a measured throw specification is needed before mounting it because the compact body alone does not establish short-throw optics.
Check the exact source and package before use
The input panel gives several ways to connect a source, but local playback file support and supported codecs can vary, so check a particular file before depending on microSD or USB. The saved page does not document an integrated streaming-app platform, ANSI output, interactive functions, or a laser light source. On any used projector, verify the model revision, power adapter, focus travel, HDMI handshake, card slot, and speaker output. Those practical checks establish whether that individual unit suits the planned setup; they do not imply hands-on testing in this guide.
What else to compare
For cordless viewing with a documented battery, compare 3M MP160; for a native Full HD portable model with HDMI and USB-C video, compare Miroir M631.
Before you buy
Is the PJ308W native 720p or 1080p?
No. GPX identifies 800 × 480 as native resolution; larger input signals are not the same as native panel detail.
Does every PJ308W version have Bluetooth?
No. GPX distinguishes version 1993 without Bluetooth from version 2190 with Bluetooth audio transmission.
Can I assume the PJ308W has an internal battery?
No. GPX lists AC/DC adapter power, but the reviewed page does not establish rechargeable battery operation.

The decision
PJ308W is a practical connector-rich mini projector only when 800 × 480 resolution and the unidentified revision fit the plan.
