Tang I Generation 12V to 220V 3000W Intelligent Car Power Inverter with Dual USB for Camping,Traveling - Black Car power inverter with 2 USB ports and AC outlet. The power inverter comes with a cigarette lighter and 2 battery clips for free,providing 300W continuous power and 3000W peak power (please ensure that the total rated power of the connected equipment is ≤300W) When the inverter is working normally,the green LED light is working,telling you that it is working normally,but when it is in a protection state,such as low voltage,high voltage,over temperature,or overload,the red LED light will be on,and the inverter needs to be turned off,Check which protection function works,try to solve it,and the inverter can work again 2 USB chargers can charge most phones and tablets at the same time (4.2A max),while the AC outlet is perfect for laptops,CPAP machines,game consoles,kindle,TV,DVD players,lights,for iPad,and other electronic equipment 12V is generally used in cars,24V is generally used in trucks,and 48V and 60V are generally used in electric vehicles. Applicable range of electrical rated voltage: 210~230V,110~130V Compatible with all automobiles,wind power,solar power,pollution-free power generation,etc. Suitable for continuous use of laptop computers in the car, With automatic protection during overload,overvoltage,over-temperature,and short circuits Strong and durable,beautiful and lightweight,convenient and practical The compact design is ideal for use on vacations,work trips,camping,and hiking It is normal for the inverter to heat up during use. For best use,place the inverter on a flat surface. The workplace should meet the following conditions: Keep it dry,do not let the inverter touch water or other liquids,and keep the inverter away from moisture or water; 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 Specifications: Input voltage: DC 10.5V~15V (When the battery voltage is lower than 10.5V,the inverter has low voltage protection when the battery voltage is higher than 15V,the inverter has high voltage protection) Output voltage: AC 220V The output frequency is: 220V 50Hz Peak power: 3000W Rated power: 300W Output waveform: modified sine wave Product size: 16.5 x 11.2 x 5.6cm Rated power below 300W applies: 5W - Mobile 5W - Breast pump 10W - Digital Electronics (Car Navigation/Digital Camera) 10W - game console 5W -10W Electric Shaver 20W - LED light 25W - walkie-talkie 50 - 100W Laptop 60W - Compact Fluorescent Lamp 60W - Incandescent lamp 60W - Mechanical Electric 9 Fans 60W - 150W TV 80W - VCR 180W - desktop computer Notes: Please make sure the power rating is higher than the appliance you are applying for. We recommend that you buy a larger model than you think you need (at least 10% to 20% more than your maximum load) If you're running multiple devices at the same time,you should refer to the total wattage If you want to run inductive loads for a long time,it is recommended to buy a pure sine wave inverter The safe range of input voltage: (please make sure this model is DC 12V,you need to use battery DC 12V) 12V: 9.8~15V 24V: 20~28V 48V: 44~53V 60V: 58~68V 8 Safety Protection Functions: Reverse polarity protection Low input voltage protection High input voltage protection Overcurrent Protection Short circuit protection Over-temperature protection Overload protection Internal fuse Attention: Connect the inverter to the battery and plug the AC device into the inverter Please do not put the power inverter in the ON position when your car is off It is recommended to use a car cigarette lighter for electrical appliances below 150W,and it is recommended to connect the battery directly above 150W Battery usage time calculation: The working time of the inverter depends on the battery power and load power. Formula: working time (hours) = battery capacity X battery voltage X 0.8X0.9/load power For example,a 12V 60A battery powers a 220V 100W light bulb Working time = 12(V) X 60(AH) X 0.8 X 0.9/100(W)=5.18(hours) Note: 0.8 battery discharge coefficient,0.9 inverter conversion efficiency Package included: 1 x Power Inverter 2 x Battery Clips 1 x Cigarette Lighter 1 x English Manual
