I have something like that in my car, but it has 2 usb connectors and a regular 12 volt connection on it. They are pretty cool!

I Would Be Careful Of Those Cheap USB Charge Charger Adapters AKS "Fire Starters"! The inexpensive brands are inexpensive for a reason, they may not carry a US UL Listing, frequently due not have an extra protection circuit, cause static becuase they use very chip chips in the circuitry that don't last long, short out, cause static and frequently don't last very long.

Before buying something electrical for your vehicle, think how much your car is worth for a $1.99 electrical item. You should understand you get what u pay for and when it fails it may cause other electrical damage to not only the device but too your vehicle as well.

I do doubt they will explode though.....

Just My Opinion, You May Get More Than You Paid For!
