Custom 7-inch 4G LTE Tablet (MTK8786) with Dual Power Input and USB Host

Model: Tablet with USB C and DC in 7-inch
Pretech R&D proficiency is highlighted by this tablet's advanced I/O engineering, utilizing the headphone jack location for a dedicated DC power input while retaining a separate Type-C port for USB Host operations. This critical feature ensures reliable data exchange (host mode). Power and Data Independence: The dedicated DC charging portensures high-current stability, isolating the power input from the data channel. This makes theUSB-C Hosta reliable, dedicated connection for high-demand peripherals. Form Factor Advantage:The 7-inch size is ideal for single-hand data captureand deployment inspace-constrained vehicles, avoiding the bulk of larger tablets. High-Intensity Power Strategy:The DC-in bypasses complex USB-C PD negotiation, enabling direct integration with various custom, large-current charging cradles—crucial for high-intensity,multi-shift work environments.
