The Vector 500-watt power inverter is the ideal solution for power when and where you need it, giving you both freedom and function. You can get 500 watts of power by connecting directly to your vehicle’s battery with the terminal posts and battery clamps for tailgating, camping, and other times when you need more power. Or use the 12V DC plug in your car for 120 watts of power to keep your laptops, phones, gaming devices and more powered up with the two USB ports.
