Material and build: Metal construction provides a lightweight, compact, and durable option with a nice texture. Its small size and footprint help save space and reduce heat buildup, lowering the risk of burning during use. Power options and compatibility: Available in two configurations, with power supply and without power supply. The Android power input port is reserved in both versions, allowing power to be supplied through a data cable to meet the power needs of largecapacity equipment and to facilitate easy data reading. If power equipment is not required, you can choose the design without a charging port for a leaner setup. Mounting and stability: Buckle design clamps securely to the edge of a display screen or a desk, preserving desktop space. The clamp is stable and stylish, providing reliable support without bulk. Use scenario 1: On a workstation, clamp to the monitor edge to access and read data from external storage or largecapacity devices while keeping the desk organized and uncluttered. Use scenario 2: In the field or onsite setups, attach to a display or workstation edge; power can be supplied via a data cable to support largecapacity equipment and ensure smooth data transfer. Use scenario 3: Portable or travel use; its metal, lightweight design and compact size make it easy to carry, enabling quick setup on any compatible display edge or desktop without adding clutter.
