It can be plugged into almost any 12V power output vehicle, providing charging opportunities anywhere.Package Included:1 x Power Inverter2 x Battery Clip1 x Cigarette Lighter Plug1 x English ManualNotes:warn -1. This is an improved sine wave inverter, not suitable for built-in motors, hair dryers, air conditioners, coffee machines, water pumps, induction cookers, refrigerators, microwave ovens and other equipment. Ensure that the total rated power of connected equipment is 300W-2. Tighten the positive ( ) and negative (-) terminals when using the on-board converter-3. If the converter is directly connected to the cigarette lighter. The maximum output power must be less than 150W. If it is higher than 150W, we strongly recommend that you use alligator clips to connect the battery, as car cigarette lighters may not be able to handle more than 150W.-4. Car converter for DC12V and Car ONLY, not for DC 24V and aircraft-5. Please do not put the inverter in the ON position before the car starts. It is easy to damage the inverter before connecting the battery. The correct operation is to connect the battery first and then turn on the inverter switch-6. It is normal for the inverter to heat up during use. In order to obtain the best use effect,Please put the inverter on a flat surface where it works should meet the following standards:1. Keep it dry, do not let the inverter touch water or other liquids, keep the inverter away from moisture or water.2. Cool environment, keep the temperature between 0 degrees Celsius and 40 degrees Celsius. Do not place the inverter next to cooling vents or other equipment. Try to avoid direct sunlight on the inverter.what size inverter do i needThe size you choose depends on the wattage (or amperage) you want to run (find the power consumption by referring to the spec plate on the device or tool). We recommend that you purchase according to your needs.
