miniature projectors

Compact projectors commonly offer HDMI inputs and support screen mirroring. Many also include USB and 3.5 mm audio ports, and several list Wi‑Fi mirroring or Bluetooth for wireless streaming and compatibility with streaming sticks.

Many mini projectors include built-in speakers and audio features such as two‑way Bluetooth, HiFi-style speakers, or 360° surround capabilities, providing usable audio without separate speakers in many cases.

Listed lamp life varies: many models indicate around 20,000 hours, some up to 30,000 hours, one lists its life as "2 Years," and at least one entry does not specify bulb life.

Mini projectors commonly offer adjustable focus (manual or auto/electrical) and keystone correction; some list automatic or ±15° keystone correction and electrical adjustment for precise alignment.

Commonly included accessories are a remote control, power cable, HDMI cable, and a user manual. Some models or shipments may also include a travel bag or simple accessory packaging.
