300W Car Power Inverters DC 12V to AC 110V Converter 4 USB Ports and 2 AC Outlets Charger

Features:
[Car Power Inverter] Car power inverter with 4 USB ports and 2 AC outlets. The power inverter comes with free cigarette lighter and 2pcs battery clips, providing 300watt continuous power, 4000watt peak power (Please make sure that the total rated power of the connected devices is 300W).
[Mobile Phone Holder] Power inverter with mobile phone holder functions, which is convenient for you to use it when charge your phone and watch video.
[Intelligent LCD Voltage Screen Display] Smart LCD Display shows the battery Input battery voltage and output voltage in real-time, when the battery voltage is lower than 10.5V, the inverter is low voltage protection, please try to charge your battery full power then try again. (When the battery voltage is higher than 15V, the inverter high voltage protection)
[Fast Charging Four USB Ports ] Two international universal AC outlets and support four USB charger ports 3.6A to work at same time and it can offer 100% fast charging for Mobile phones, computers, laptop,breast pump, nebulizer, Razors, medical rescue device, emergency equipment etc. Easily meet the power supply needs of the diverse vehicle electrical appliance and it can be as a emergency power supply.
[Multi Protection] Built-in fuses, safe charging design and cooling fan prevents the car power converter from over-heat, saving power and energy, over voltage, overload, over-current, short circuiting, under-voltage, overheating, short circuit protection.
[Lightweight Design Top Quality] Lightweight and compact, ideal for vacations, camping and work trips. It can be plugged into almost any 12V power output vehicle, providing charging opportunities anywhere.
Note:
①Please Ensure the Rated Power is higher than the electric appliance you wanna apply to. We 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 time, you should refer to the total Watt.
③If you wanna run a inductive load for a long time, it`s suggested to buy a pure sine wave inverter.
CAUTION!
1. This is a modified sine wave inverter, NOT applicable for devices which work by built-in motor, hair dryers, air conditioners, coffee machine, water pump, induction cooker, refrigerators and microwave ovens etc. Make sure that the total rated power 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 cigarette lighter. The highest out put power must be under 150W. If higher than 150W, we strongly recommend you using the Crocodile Clips to a battery, because car cigarette lighter might not afford power 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 start. It's easy to damage the inverter before connected to the battery. The correct operation is connect to the battery 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 best 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 contact the water or other liquids, keep the inverter away from moisture or water.
②Cool 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.
Battery Usage Time Calculation:
(1)The working time of inverter, it is depend on the battery power and load power.
(2)Formula: Working time (hours)= Battery Capacity X Battery Voltage X 0.8X0.9/Load Power.
(3) For example, the battery of 12V 60A is supplied to a 220V 100W bulb.
The working time is = 12(V) X 60(AH) X 0.8 X 0.9 / 100(W)=5.18(hours)
