9V 1A 2A Car DC Power Adapter with 5.5x2.1mm Barrel Jack, Cigarette Lighter Socket Vehicle Step Down Converter, Auto Power Supply Transformer for Router CCTV Camera Portable Electronic Devices

This car cigarette lighter power adapter is a portable DC-DC step-down converter designed to convert the standard 12V output from automobile cigarette lighter socket into regulated steady 9V direct current, offering reliable mobile power supply for small electronic devices when you are driving or on road trips.

It comes with a classic 5.5*2.1mm DC male barrel connector, which is the most common power interface for wireless routers, portable surveillance cameras, mini LED light panels, small audio players, testing instruments, portable fans and many other 9V low-power gadgets. Two current specifications of 1 Amp and 2 Amp are optional to match the rated power of your equipment, preventing insufficient power startup or unstable working state.

The internal high-efficiency buck circuit features low energy loss and low heat generation during continuous operation. Integrated complete safety protection modules including over-current cutoff, over-voltage lockout, short-circuit protection and high-temperature automatic shutdown effectively avoid burnout of the adapter and connected load caused by unstable vehicle power or accidental wiring faults.

The streamlined lightweight housing takes up limited space in the car storage area, directly plug into the cigarette lighter port without extra wiring. The built-in strain relief structure at the wire root prevents internal wire breakage from frequent bending and pulling during vehicle bumping.

Widely applicable for cars, SUVs, trucks and vans with standard 12V cigarette lighter sockets. Please confirm your device required voltage (must be strictly 9V) and working current before ordering to guarantee safe and normal operation.
