Battony USB C to HDTV Adapter 4K

This compact USB C to HDTV adapter makes it easy to mirror or extend a laptop or tablet screen to a TV, monitor, or projector while keeping a charging cable connected. If you need a portable multiport solution for presentations or media playback, this USB C to HDTV adapter supports up to 4K UHD output and simultaneous fast charging for a smoother workflow.

Key Points

The adapter combines three common connections into a single dongle so you can connect an HDMI display, a USB-A 3.0 device, and a USB-C power source without carrying multiple cables. It is plug-and-play, which means no drivers are required for most modern laptops and tablets, and the aluminum shell helps with heat dissipation during longer sessions. 🎬

Transfer speeds are rated up to 5 Gbps for the USB 3.0 port, allowing quick file moves from flash drives or external drives and responsive operation with peripherals like keyboards and mice. The HDTV output supports 3840 x 2160 at 30 Hz according to the manufacturer, so sharp images and video playback are available when paired with a compatible HDMI cable and display. ⚡

Consider that 4K output is limited to 30 Hz, which may not suit high frame rate gaming. Additionally, the actual charging power delivered depends on the host device and the power adapter used, so charging behavior can vary according to the manufacturer.

Usage Recommendations

For the best video performance use an HDMI 2.0 or higher cable and ensure the host device supports DisplayPort Alt Mode over USB-C. When giving presentations or streaming video, connect the power adapter to the USB-C charging port so the laptop or tablet maintains battery level while sending video and data. For file transfers and peripheral connections, plug USB storage or input devices into the USB-A port while monitoring transfer speed, especially with large files.

If you plan to use the adapter with older displays or cables, check the monitor’s supported resolutions and refresh rates to avoid mismatches. The compact size makes it convenient to carry in a laptop bag for travel or for moving between meeting rooms, and the aluminum housing reduces thermal buildup during extended use.
