Delivery Contents : 1 x Inverter 2 x alligator clip cables 1 x lighter cable 1 x Manual Please Notice: 1. Please ensure that the rated power is higher than the appliance you want to apply. 2. If you want to run several devices at the same time, you should refer to the total wattage. 3. If you want to run the inductive load for a long time, choose the Pure sine wave inverter . 4. Please use the standard battery cables we sent, or a full power output may not be guaranteed. And the spare fuses in the package are just used when the original ones are burned by accident. 5. Please do not connect the inverter with the grid power, and a reverse connection of positive and negative is also forbidden. 6. Please do not overload. If your applications are inductive loads, please choose the inverters whose continuous power is 3-7 times higher than the watts of your appliances. such as fridge, icebox, drill, washing machine, water pump, microwave oven, oven, vacuum cleaner, hair dryer, etc. with motor inside.
