Product Features
Four-Module Power Hub: The panel combines a USB-C and USB-A charger, digital voltmeter, 12V socket, and illuminated control switch. The integrated layout centralizes charging, monitoring, and accessory power in one installation.
Dual-Port Device Charging: The charging module provides USB-C PD and USB-A QC3.0 connections for compatible devices. The shared module reduces separate dashboard cutouts for modern charging ports.
Live Voltage Monitoring: The independent digital voltmeter displays the connected DC system voltage. The visible reading helps track battery condition in cars, boats, RVs, trucks, and utility vehicles.
Controlled Accessory Power: The blue LED rocker switch provides manual control of the installed circuit. The covered 12V socket accepts compatible plug-in accessories while limiting debris entry when closed.
Prewired Aluminum Panel: The aluminum faceplate arrives with snap-in modules and rear spade wiring installed. The compact rectangular format supports clean custom dashboards and equipment panels.
