Sea-Dog Round USB & USB-C Power Plug w/Voltmeter

The Sea-Dog Round USB & USB-C Power Plug w/Voltmeter is a dual-port charging solution designed for mobile operations in vehicles, vessels, and recreational equipment where simultaneous device charging and real-time power monitoring are critical. Law enforcement and military personnel routinely deploy across multiple platforms—patrol vehicles, command centers, tactical operations centers, and field bases—where reliable 12V or 24V power distribution to communications devices, navigation units, and tactical tablets can mean mission success or failure. This compact power plug solves the universal problem of dead batteries during extended operations by providing redundant charging pathways and instant voltage feedback.

The unit features dual USB 3.0 and USB-C output ports capable of delivering up to 6A total load capacity, intelligently split at 3A per side as operational demand requires. The integrated LED voltmeter display continuously monitors incoming voltage, allowing operators to assess vehicle or power system status at a glance—a critical feature when battery voltage drop can disable communications or navigation equipment. The round design allows seamless integration into most standard 12V/24V power systems found in marine applications, automotive installations, and RV platforms, with compact 3 x 2 x 5 inch dimensions enabling discrete mounting in tight operational spaces. The dual-port architecture ensures that two devices charge simultaneously without sacrificing output efficiency.

This power solution is essential for tactical teams operating in vehicles with extended missions, law enforcement units managing fleet charging standards, maritime security personnel, and anyone requiring simultaneous dual-device charging in field environments. The voltmeter function provides immediate system diagnostics—a dead battery or failing alternator becomes visible instantly, preventing mission-critical power loss. Compatible with any device featuring standard USB or USB-C inputs, the Sea-Dog Round plug integrates seamlessly into existing tactical power ecosystems and meets the redundancy requirements of professional field operations.
