DC to AC Adapter Cords

Plug these cords into a vehicle socket to charge devices that run on AC voltage.

Barrel-Style DC Power Cords

Carry DC power in or out of electronic devices with these cords. All have industry standard barrel-style connections, letting you power electronics from power supplies.

Barrel-Style DC Power Cord Splitters

Send DC power to multiple electronics from one source. With industry standard barrel-style connections, these splitters are compatible with many power supplies and other devices.

Vehicle Extension Cords

Plug these cords into a vehicle outlet to power a device from the vehicle's battery.

Electrical Connectors

Build-Your-Own Weatherproof DC Connectors

Configure a connector for your application by combining housings with pins and sleeves for different wire sizes. Also known as weather-pack connectors, they withstand moisture, harsh engine fluids, and high temperatures.

Weatherproof DC Connector Sets

Each set includes one plug and one socket. These connectors withstand moisture, harsh engine fluids, and high temperatures. Also known as weather-pack connectors.

Ready-to-Use Weatherproof DC Connectors

Quickly replace or add connectors to an existing wiring system—connectors come assembled with wire leads already installed. Also known as weather-pack connectors, they withstand moisture, harsh engine fluids, and high temperatures.

Deutsch-Style DC Connectors

Use these connectors in vehicles and other agricultural and construction equipment. They have a sealed nylon housing that resists dust and temporary submersion.

Barrel-Style DC Connectors

Made with industry standard barrel-style ends, these connectors carry DC power between electronic devices and power supplies.

Panel-Mount Deutsch-Style DC Connectors

Install these connectors in panels, enclosures, and bulkheads to join equipment with compatible Deutsch-style DC connectors.

Turn-Lock Vehicle DC Connectors

Connectors lock into place for a secure connection in high-vibration environments. They power small devices, such as chargers for electronics, from a vehicle. Also known as cigarette-lighter plugs and sockets.
