wifi mini projectors

Listings show a mix of focus and keystone options: manual or motorized (electric) focus, with auto-focus on some models. Keystone correction commonly ranges from about ±15° to ±30° and may be manual, automatic, or electrically adjustable depending on the model.

Many listings state no internal battery. Some portable models include a built-in rechargeable battery (one listing cites a 7000mAh pack with up to 2.5 hours runtime), and several items note compatibility with external battery packs for portable use.

Many listings mention dual‑band 2.4 GHz/5 GHz Wi‑Fi and built‑in Bluetooth for audio pairing. Several product descriptions explicitly reference Wi‑Fi 6 and list Bluetooth versions such as 5.0, 5.1, or 5.2.

Listings commonly show native 1080p and native 720p projectors. Several descriptions also note 4K decoding or 4K input/support even when the projector’s native panel resolution is 1080p or 720p.

Some listings include an onboard smart OS or app store so the projector can run streaming apps directly. Other listings expect you to connect an external streaming stick or device (via HDMI) to access apps.
