The PK320’s lamp life is another significant advantage, boasting an impressive lifespan of up to 20,000 hours in eco mode. This longevity means users can enjoy their projector for years to come without the need for frequent bulb replacements, thereby reducing maintenance costs.

Additionally, the PK320 includes built-in speakers that provide sufficient sound quality for small group presentations and casual viewing. While it is recommended to use external speakers for larger gatherings, the onboard audio functionality is a handy feature for portable use.

Overall, the Optoma PK320 combines portability, solid performance, and user-friendly features, making it a versatile choice for anyone in need of a compact projector. Whether for business, education, or entertainment, the PK320 is well-equipped to meet diverse projection needs.
