Color:2000W Please use battery clips when using inverter on device over 150W. Cigarette lighter sockets provide a total power 150W, Cigarette lighter adapter can not power laser printer. This inverter is with "modified sine wave" that's perfectly fine for resistive products, not work good for inductive products. If you need to use for appliance using a motor or a delicate piece of medical equipment,you need a "pure sine wave" inverter Specifications: Power (2 AC Outlets): 1000W Rated, 2000W Peak Output wave: modified sine wave Nominal input voltage:12.8-13.2VDC Nominal output voltage: 220V-230V AC Battery cables:One black,one red. What's in the box: 1 x power inverter 2 x Battery Clip 1 x Cigarette Lighter Plug Optimal Use / Precautions: Converts DC power in your 12V batteries in your car, truck, boat or any other DC power sources into the AC power that home appliances, electronics and tools need. If the rated input of any connected AC devices exceed 150W use the included battery clamps to directly connect to your vehicle’s battery as most vehicles 12V ports are rated and fused for 150W. Always make sure that the total rated power of the connected devices is less than 1000W. Avoid placing the inverter in a location that receives prolonged direct sunlight or near to heat sensitive materials as the inverter can become warm during use. Always tighten the Positive (+) and Negative (-) terminals when the inverter is in use otherwise a loose connection can overheat due to poor contact. Cigarette lighter adapter for device under 150W , If you run TV, Printer need battery clips. Otherwise,Our Inverter will continually shuts down and sounds an alarm to indicate it is being overloaded.
