Triple Car Cigarette Sockets Power Adapter with USB Power Port - Black (DC 12~24V)

Pros: Manufacturing quality is excellent, nice plastic case, with no chipping and spew. There is a backlight mode for each slot separately (red off, blue on). Packaging as in the description. A good wire, flexible insulation, the normal section of copper rather than steel or aluminum copperplated.

Cons: Plastic smells a little chemistry (in theory, fade quickly). Seemed too small for the length of the wire, we could see 60 to do so in any car approached.

Other: An excellent choice for sooo humane price. I recommend!

Pros: Useful if you have few devices in your car: video recorder, phone, tire pressure monitor, navigator.

Cons: Too thin wire! Immediately change it before use: risk of fire if you attach more than 1 device.
In general, the idea to gave switchers on sockets is good, but realization of idea is wrong. You either have switchers down (and they are not convenient in use. no lighting seen) or you have them up (and plugs of devices fall out to the floor time after time because of vibration).
It's only one USB socket, it would better have two or three.

Other: Think how and where you will use it and then purchase.
