Sturdy Case MadING of aluminum, it is more durable than other plastic cases. A slight drop or impact will not affect the internal parts. Cooling Fan More comfort, less heat. The cooling fan is normally started at 1/3 of the rated power of the inverter. After rotating, the efficiency will not decrease, but increase. 0~2.4A USB High speed charging Safe charging design provides protection against, overheating, under and over voltage charging, short circuiting, overloads, and overcharging. Remote Control Inverter with Remote Control: cable length 15ft,the long cable will help you control the inverter ON/OFF easily. GIANDEL A leading Global inverter brand in USA,UK,AUSTRALIA,GERMANY,etc,our factory has been devoted to producing quality products for over 20 years. Giandel inverters has been must-have for your road trips, vacations, outdoors, emergency kits and more. GIANDEL pure sine wave inverters are more compatitable and widely used for inductive loads such as Laptop, Linear Adaptor, switching power supply, motor,freezers,fans and so on. They decrease the rush current and have lower interference,reduce the noise,prolong the device life.

Remote Controller with 15ft cables Built-in intelligent cooling fan: Will run automatically when the temperature reaches 104℉ or load power is more than 40% of rated power. Over-temperature Protection: Around 149℉ Over-voltage Shutdown: 16V±0.5VDC Under-voltage Alarm: 9.8V±0.5VDC Under-voltage Shutdown: 9.5V±0.5VDC Over load protection: 2200W-2500W ATTENTION: Connect the inverter to a 12V battery with the standard cables provided with product, and plug your AC devices into the inverter. Please do not leave the power inverter in the ON position while your car is off. Disconnect the positive battery terminal before doing any wiring to the inverter. Do not put the inverter into sunlight directly, keep it in cool and dry environment. Don’t use the inverter with a product that draws a higher wattage the inverter can provide, as this may cause damage to the inverter and product.
