Sea-Dog 426112-1
Surface-mount 12V socket includes plug and cap; screws are not included.
Identify Sea-Dog 12V Power Sockets and Dual USB Outlets
A round socket, a USB power socket and a USB plug adapter may all be used with marine 12V equipment, but they install differently. The Sea-Dog 426513 plugs into an existing accessory receptacle; the 426515 and 426517 are wired into a panel. Use the original cutout, supply voltage and charging requirements to identify the correct component.

| 426120-1 | 12V accessory socket | Receptacle, cap, speed nut and hardware | 12V DC, 16A max | 1-1/8-in hole |
| 426513-1 | Portable 12V-receptacle charger | Fits a compatible standard 12V receptacle | 12–24V input; 5V/4.8A total output | No panel cutout |
| 426515-1 | Panel-mounted two-port USB | Hardwired input | 8–32V input; 5V/4.8A total output | 1-1/8-in hole |

Before selecting a replacement: USB output amperage is not the same as the boat's 12V input current. Part 426513-1 is a plug-in USB charger for a compatible receptacle, not a permanently installed socket. The 426515-1 is rated 5V/4.8A combined; the 426517-1 is 5V/4.2A combined and has a hidden voltage display.
Inspect the existing component
- Decide whether you need a 12V accessory receptacle, a permanently wired USB socket or a removable plug-in USB adapter.
- Check the mounting: 426112 uses a two-screw surface mount; the deluxe sockets and round USB outlets use an approximately 1⅛-inch opening.
- Verify the input voltage. Accessory sockets are 12V DC; the listed USB models accept wider DC input ranges.
- Compare the included hardware: 426112 has plug and cap but no mounting screws; 426115 has socket and cap; 426120 lists mounting hardware.
- Provide appropriately protected DC wiring and check the USB device's charging needs; a higher output rating does not guarantee every fast-charge protocol.
