The specific features indicated on the box, such as HD and 4K support, are common marketing terms for these types of projectors. However, "4K support" often means the projector can accept a 4K video signal as input, but its native display resolution is typically lower, such as 720p or 1080p.
Since the specific manufacturer or model name is not on the box, the exact specifications can vary. These mini projectors often offer:
Portability: Compact and lightweight design for easy transport.
Connectivity: Multiple ports like HDMI and USB, and often include Wi-Fi and Bluetooth for screen mirroring from smartphones or other devices.
Built-in features: Some models run on an Android operating system with pre-installed apps like Netflix and YouTube, and may have built-in speakers.
