12V to 5V USB converter (8-35V input) – 2x USB 3A power supply

This compact DC-DC converter converts an input voltage from 8V to 35V to a stable 5V USB power supply. This allows you to power USB devices directly from a battery or DC installation, such as in cars, campers, trucks and boats. The stable 5V output is suitable for both charging and permanently powering devices that you would rather not connect via a separate cigarette lighter adapter.

With two USB outputs you can connect multiple devices at the same time, such as a smartphone, tablet, dashcam, GPS or a compact router. Due to its small size, this inverter is ideal for permanent installation and neatly concealed behind a dashboard, in a panel or in a connection box.

Stable 5V USB power supply from 8–35V DC

Many equipment runs on 5V via USB, while the available power supply in vehicles and installations is often 12V or 24V. This step-down converter reduces the voltage to 5V and keeps the output stable, so connected devices continue to work reliably.

Because the input range is 8–35V, this is a practical solution for both 12V vehicles and 24V systems. So you don't have to look for a separate converter if you want to use the same USB power supply in different vehicles or installations.

2x USB output for simultaneous use

The converter has two USB Type-A ports so you can connect two devices at the same time. Think of a dashcam and telephone, or a GPS and tablet. The maximum output current is a total of 3A, shared between both ports.

This makes the converter suitable for situations in which you want to create a fixed USB power supply in a place where you normally do not have a USB connection, for example behind the dashboard or in a surface-mounted panel in a camper.

Ideal for dashcams and fixed vehicle installations

A fixed power supply is often the neatest solution for dashcams and vehicle cameras. Instead of a cable to the cigarette lighter, this converter can be connected behind the dashboard to a switched plus, so that the dashcam automatically turns on when you switch on the ignition.

This is also a practical way to make a reliable 5V connection without separate adapters for accessories such as GPS systems, USB-powered vehicle trackers or small cameras.

Applications in car, camper, truck and boat

Thanks to the wide input voltage range from 8V to 35V, this converter can be used in a variety of DC systems. This makes it suitable for both 12V and 24V environments and you can use it for all kinds of mobile and fixed applications.

Common applications are:

– Charging smartphones and tablets while driving
– Powering dashcams, vehicle cameras and mini cameras
– Power supply for GPS systems and navigation equipment
– USB power supply for compact routers or peripherals in campers
– Create a USB connection in places without a standard USB port

Compact design for concealed mounting

The inverter is compact and therefore easy to conceal. This is useful if you want a neat installation without visible adapters or protruding chargers. Placement behind a dashboard, in a panel or in a junction box is often easy due to the small dimensions.

The converter is connected with two wires (plus and minus). Once the power wires are connected, the USB ports are ready to use.

Technical specifications
