This device is really simple to use. Plug it into your car's cigarette lighter outlet and convert that power into two USB ports and an AC outlet. The USB ports can automatically detect what device you are plugging in to provide the best possible charge, and the 110V AC outlet is strong enough to power larger devices like your laptop. There are multiple layers of protection, including a built-in safety door to keep prying hands safe, and safeguards against things like overcharging, overheating, and more. It also has voltage protection with low and high-pressure isolation. It comes with an 18-month warranty, and users give it 4.2 stars based on over 150 reviews.
