Description

12V Cigarette Lighter to DC Barrel Jack Power Adapter – 3A, On/Off Switch, LED Indicator (5.5mm × 2.1mm)

A compact 12V power adapter that converts your vehicle’s cigarette lighter socket into a standard DC 5.5mm × 2.1mm barrel jack output — the most common DC power connector used by LED strip lights, CCTV cameras, dash cams, GPS units, and a wide range of 12V accessories.

The 5.5×2.1mm DC barrel connector is the standard interface for powering car monitors, cameras, CCTV, LED strip lights, dash cams, GPS units, air compressors, and speakers.

On/Off Switch with LED Indicator

The built-in push-button switch lets you cut power to your connected device without unplugging from the cigarette lighter socket. The red LED indicator confirms power is on — useful when the device itself has no power indicator.

3A Rated

Built-in 3A fuse protects your car circuit and connected equipment — durable and safe to use. Suitable for LED strips, dash cams, small CCTV cameras, GPS units, and similar low-current 12V accessories. Not suitable for high-current devices like compressors or fridges.

Compact 240mm Cable

Short 240mm cable keeps the adapter tidy when plugging directly into a centre console or dash-mounted cigarette lighter socket — no excess cable to manage.

Common uses:

• LED light strips in the cab, tray, or motorhome
• Dash cam power supply
• CCTV camera power in van or motorhome
• GPS and navigation devices
• CB radio accessories
• 12V fans and accessories

Note: Centre positive polarity (tip = +, sleeve = −). Confirm your device uses the same polarity before connecting. Not compatible with devices requiring 2.5mm inner diameter barrel jack — check your device’s connector size before ordering.
