With the KB-7985 power supply, you can connect your 12 V devices to a 230 V socket. You can then use these devices not only in the car but also at home, in the office, or at the campsite. The power supply converts 100 to 240 V at the input to 12 V at the output. This allows you to connect 12 V devices to a 230 V power source. This is particularly useful if you want to connect your 12 V cooler at the campsite or at home while grilling.
