You will find everything for transport vehicles at Work System. Having functional and smart solutions for electronics and power supply is becoming increasingly important. An inverter or current converter helps you convert a battery's direct current into alternating current when you want to get out, for example, 230V to electric machines and tools. Having an extra battery or charger in your vehicle is useful when you have many machines and tools. Most of our products are available as individual parts or assembled as ready-made kits.
