Cigarette lighter cable can supply power for device easily. If the out put power is higher than 150W, please using the Crocodile Clips to a battery.</p> <p>[Fast Charging Dual USB ports ] One AC Outlets and two usb ports can offer 100% fast charging for Mobile phones, computers, laptop,breast pump, Nebulizer,Razors,medical rescue device,emergency equipment etc,can be as a Emergency Power Supply</p> <p>[Multi Protection] Built-in fuses, safe charging design&nbsp; 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.</p> <p>[Lightweight design &amp;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.</p> <p>CAUTION!</p> <p>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.</p> <p>2. Tighten the Positive (+) and Negative (-) terminals when the car converter is in use.</p> <p>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.</p> <p>4. The car converter suitable for DC 12V and Car ONLY, not applied for DC 24V and airplane.</p> <p>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.</p> <p>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.</p>
