Features:* LED Green & Red Work Lights: When inverter work normal, the green LED Lights work and tell you it is working well, but when it is on protection status, such as low voltage, high voltage, over temperature, or over load, the Red Led Lights will light up and you need to turn off the inverter, and check which protection function is work, and try to solve it then the inverter can work again.* LED Voltage Screen display: LED Display shows the battery Input voltage, output voltage. Cigarette lighter cable can supply power for device easily. If the output power is higher than 150W, please using the Crocodile Clips to a battery.* 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 an 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. What Size Power Inverter Do I Need?The size you choose depends on the watts (or amps) of what you want to run (find the power consumption by referring to the specification plate on the appliance or tool). We recommend you buy a larger model than you think you'll need (at least 10% to 20% more than your largest load). Specification:1.
