Coming Xiao Mi 4k Laser Projector ultra Short Throw Laser Projector for xiaomi 1s 4k Projector

The projector has a native 4K physical resolution of 3840 x 2160 for crisp, detailed images.

Ultra short throw means the projector can produce a very large image while being placed very close to the projection surface. This reduces shadows and allows use in small rooms or on a low cabinet directly in front of the screen or wall.

Brightness is rated at approximately 2000–2500 ANSI lumens. That makes it well suited for dim to moderately lit rooms; for very bright environments, additional room darkening will improve image quality.

The projector has a contrast ratio of 3000:1, which helps deliver deeper blacks and better image depth compared with lower-contrast projectors.

No. The specifications indicate there is no built-in battery, so the unit requires mains power during operation.

Yes, the product is described as portable. Note that the single package gross weight is listed at about 12.0 kg, so while transportable, it is not ultra-lightweight.

The projector runs Android 7.1 and includes built-in internet capability for streaming and web browsing via available apps.

It comes with 2 GB of RAM and 16 GB of internal storage. This should support basic apps and media storage; additional storage needs may require external solutions if supported.

Yes, the projector includes built-in speakers for audio playback. For fuller, louder sound (home theater or events) you may prefer connecting an external sound system if supported.
