Outside Supply had a call today from a dump truck owner needing to power a device that logs tickets and loads on a laptop computer. He was looking for a power inverter that would run the laptop from a cigarette lighter. He was very interested in the durability and simplicity of the power inverter.
We suggested a 150 watt true sine wave inverter for his dump truck.
Here is the setup we recommended.
