Mini projector for casual viewing

The GPX PJ300B is a compact mini projector with a native 800 x 480 resolution and 16:9 aspect ratio. It delivers 42 ANSI lumens of brightness and includes built-in speakers for immediate audio. The unit measures 7.87" x 6.06" x 3.27" and ships with a remote control, a 3.5mm to 3 x RCA cable, and an AC/DC power adapter.

Suits dark-room portability not bright spaces

This projector suits users who need a highly portable display for low-light environments such as bedrooms or camping tents. Its low ANSI lumen output makes it unsuitable for rooms with ambient light or for audiences requiring a large, vivid image. Buyers who need high brightness for conference rooms or daytime viewing should look at higher-lumen models instead.

42 ANSI lumens determines usable environment

The 42 ANSI lumen rating is the single specification that defines where this projector works. It restricts practical use to dark or very dim settings and limits the maximum viewable image size. If your installation cannot guarantee near-total darkness, this brightness level will not meet the requirement.

Questions about this item

How do I set up the PJ300B at the correct throw distance for a focused image?

Place the projector between 3.9 ft and 12.1 ft (1.2 m to 3.7 m) from the screen; the step most people miss is measuring from the lens, not the rear panel, and adjusting the focus ring after positioning.

What consumables will the PJ300B need over time?

The remote control requires two AAA batteries, which are not included in the box and will need replacement as they deplete.

How long can I run the PJ300B continuously before brightness drops noticeably?

The 42 ANSI lumen rating is measured under standard test conditions; sustained use in a warm room will cause the LED light source to dim gradually, so plan viewing sessions with breaks to maintain perceived brightness.
