Features:
[Car Inverter] Car inverter with 4 USB ports and 2 AC outlets. The inverter comes with free and 2pcs clips, providing 300watt continuous , 4000watt (Please make sure that the total rated of the connected devices is ≤ 300W). 
[ Holder] inverter with holder functions, which is convenient for you to use it when your and watch video.
[Intelligent LCD Voltage Screen Display] LCD Display shows the Input voltage and output voltage in real-, when the voltage is lower than 10.5V, the inverter is low voltage , please try to your full then try again.  (When the voltage is higher than 15V, the inverter high voltage )
[ Four USB Ports ] Two international universal AC outlets and support four USB ports 3.6A to work at same and it can offer 100% for Mobile phones, computers, laptop, pump, , Razors, device, equipment etc. Easily meet the needs of the diverse vehicle electrical appliance and it can be as a .
[Multi ] Built-in fuses, design and cooling fan prevents the car converter from over-heat, saving and energy, over voltage, overload, over-current, short circuiting, under-voltage, overheating, short circuit .
[Lightweight Design & Quality] Lightweight and compact, for vacations, camping and work trips. It can be plugged into almost any output vehicle, providing opportunities anywhere.

Note:
①Please Ensure the Rated is higher than the electric appliance you wanna apply to. recommend you buy a larger model than you think you'll need (at least 10% to 20% more than your largest load).
②And if you wanna run several appliance at the same , you should refer to the total Watt.
③If you wanna run a inductive load for a long , it`s suggested to buy a pure sine inverter.

CAUTION!
1. This is a modified sine inverter, NOT applicable for devices which work by built-in motor, hair dryers, conditioners, coffee machine, pump, induction cooker, refrigerators and microwave ovens etc. Make sure that the total rated of the connected devices is ≤ 400W.
2. Tighten the Positive (+) and Negative (-) terminals when the car converter is in use.
3. If the converter is directly connected with the . The highest out put be under 150W. If higher than 150W, strongly recommend you using the Clips to a , because car might not afford over 150W.
4. The car converter suitable for DC12V and Car ONLY, not applied for DC 24V and airplane.
5. Please do not leave the inverter in the ON position before car . It's easy to damage the inverter before connected to the . The correct operation is connect to the first and then turn on the inverter switch.
6. It's normal for the inverter to become warm while you are using it. In order to get the using results, please put the inverter on the flat surface. The working place should meet the following criteria:
①Keep dry, should not let the inverter the or other liquids, keep the inverter away from or .
②Cool environment, keep the between 0 Celsius degrees and 40 Celsius degrees. Do not put the inverter to heat vents or other devices. Try to keep the inverter not be shined directly by the sunshine.

Usage Calculation:
(1)The working of inverter, it is on the and load .
(2)Formula: Working (hours)= Capacity X Voltage X 0.8X0.9/Load .
(3) For example, the of 60A is supplied to a 100W .
The working is = 12(V) X 60(AH) X 0.8 X 0.9 / 100(W)=5.18(hours)
