For video: many projectors support wireless screen mirroring over Wi‑Fi or wired connections such as HDMI, micro‑HDMI and USB. For audio: use the projector’s built‑in speakers, Bluetooth audio, or a 3.5mm audio jack (where provided).

Projectors range from compact, lightweight units to larger portable models. Reported weights in the results run from about 1.4 pounds up to roughly 10.23 pounds, and physical dimensions vary accordingly depending on the model.

Common options include built‑in speakers (some advertise Hi‑Fi or 360° sound) and Bluetooth audio support — some listings show two‑way Bluetooth or Bluetooth 5.x — so you can use the projector’s speakers or stream to external Bluetooth speakers.

Many listings say “Battery: No Battery Used.” Some projectors include a built‑in rechargeable battery (for example, a listed 7000mAh rechargeable battery), a few list replaceable batteries (e.g., “2 AAA Zinc Air, Required, Not Included”), and some note compatibility with external batteries.

Wired ports commonly listed are HDMI (and micro‑HDMI), USB and a 3.5mm audio jack; some listings also show component audio. Wireless options frequently mentioned include Wi‑Fi screen mirroring (2.4GHz/5GHz) and Bluetooth audio.

Many listings describe Wi‑Fi screen mirroring (including 2.4G/5G) and some explicitly call out Miracast and AirPlay support. A few notes warn that protected streaming apps may not mirror directly; in those cases a TV‑stick accessory (or a projector with built‑in smart streaming) can be used to run apps. Some models also advertise built‑in smart streaming or wireless synchronization for phones.
