Please do not leave the voltage converter in the ON position when the car is turned off. It is recommended to use a car cigarette lighter when electrical appliances are less than 150W and connect to the battery directly when the power is more than 150W. It is normal for the inverter to get hot when using it. For best results, place the inverter on a flat surface. The workplace should meet the following criteria:1. Keep dry, do not let the inverter go with water or other liquids, keep the inverter away from moisture or water.2. Cool environment, keep the temperature from 0 degrees centigrade to 40 degrees centigrade. Do not place the inverter next to air vents or other appliances. Try not to let the inverter shine directly through the sun. What size voltage converter do I need? The size you choose depends on the watts (or amplifiers) of what you want to run (find the power consumption by referring to the device or tool's spec board). We recommend buying a larger model than you think you'll need (at least 10% to 20% more than the heaviest load).
