Most listings show manual or adjustable focus. Keystone correction varies by model: some offer automatic vertical keystone correction, some provide manual keystone adjustment (vertical and/or horizontal), and others combine manual focus with automatic keystone features. Check the product listing to see which focus and keystone options a specific model includes.

Power options vary across listings. Some models have no internal battery and require external power, a few use replaceable batteries (for example, 2×AAA), others include a built-in rechargeable battery, and several support powering from USB power banks. Always check the product specification to confirm battery type, capacity, and whether power-bank operation is supported.

Mini projectors range from very small pocket-sized units to larger portable models. Examples from listings include compact pocket-style dimensions around 4×2×5 inches at about 1 lb, mid-size listings near 5.9×3.9×0.9 inches at ~2.6 lb, and larger portable units around 7×3×9 inches approaching 5 lb. Exact size and weight depend on the model and feature set.

Many models include built-in Hi‑Fi or stereo speakers; a few list specific speaker power (for example, a 3W speaker). Several projectors provide an audio output port for headphones or external speakers, and some support Bluetooth pairing to send audio wirelessly to external speakers or headphones. Check the listing for speaker power and Bluetooth/audio output details.

Lamp/LED lifetimes in the listings vary. Common figures include 50,000 hours (reported in many entries), a 55,000‑hour figure in one result, and lower values such as 20,000 or 5,000 hours in other listings. Check the product specification to see whether the listed figure refers to typical LED lifetime, rated lamp hours, or an estimated operational life.
