Marinco Sealink Dual Port USB-A and USB-C Combo Charger

The Marinco Sealink Dual Port USB-A and USB-C Combo Charger is a marine-grade charging solution designed for vessels, RVs, and outdoor power systems where dual-device charging capability is essential. Built for wet environments and saltwater exposure, this charger eliminates the need to choose between legacy USB-A devices and modern USB-C equipment—both can charge simultaneously from a single 12V electrical circuit. Its rugged construction makes it ideal for boaters, sailors, and off-grid users who demand reliability in harsh conditions.

This combo charger features one USB-A port and one USB-C port, allowing simultaneous charging of two devices without sacrificing compatibility with either standard. The unit mounts directly into a standard 1 1/8" hole, enabling flush integration into dashboard panels, console trim, or bulkhead installations without requiring external adapters or brackets. A water-resistant cap seals the charging ports when not in use, preventing corrosion and saltwater intrusion—critical protection for marine applications. An integrated LED power indicator provides instant visual confirmation of 12V supply availability, helping users troubleshoot electrical issues quickly.

Boaters, campers, and fleet operators benefit most from this dual-port design, as crew members can charge phones, tablets, and navigation devices simultaneously without waiting for port rotation. The charger's compact 0.21 lb profile and standard hole format make it a drop-in replacement for single-port units on existing vessels or a straightforward addition to new installations. Marinco's Sealink line is engineered to withstand constant moisture exposure and UV degradation, making this charger a trusted choice for extended time on water or in remote locations where charging infrastructure is limited.
