Attention:--Connecting the inverter to a battery, and plug your AC devices into the inverter.--Please do not leave the power inverter in the ON position while your car is off.--It's recommended to use the car cigarete lighter when electrical appliances less than 150W and connect to the battery directly when more than 150W.--It's normal for the inverter to become warm while you are using it.In order to get the best using results, please put the inverter on the flat surface The working place should meet the following criteria:1. Keep dry, should not let the inverter contact the water or other liquids, keep the inverter away from moisture or water.2. Cool environment, keep the temperature between 0 Celsius degrees and 40 Celsius degrees. Do not put the inverter next to heat vents or other devices. Try to keep the inverter not be shined directly by the sunshine.
What Size Power Inverter Do I Need?The size you choose depends on the watts (or amps) of what you want to run (find the power consumption by referring to the specification plate on the appliance or tool). We recommend you buy a larger model than you think you'll need (at least 10% to 20% more than your largest load).
