12V DC 5.5mm x 2.1mm Car Cigarette Lighter Power Adapter Cable by JacobsParts - 2.5 Feet Review

Need a new cord to replace the damaged one. The power cord is almost an exact duplicate of the one I had. I am happy with my purchase.

No return - information not available on product page. The size is too big for what I need it for - apparently a common problem. waste of time and money.

Designed to service my 12v lithium power bank. Don't let the engine idle. At full speed, the alternator delivers the higher voltage that my device really needs to charge (15V), which has proven to be sufficient.

Didn't fit the gpx cd player I bought to go with it. It has been listed as a compatible accessory for the CD player on the amozion website. I have just realized that this item cannot be returned for a refund or exchange. I'm really mad at Revain because the charger was advertised as the correct charger for the GPZ CD player.

Well done with a cord that can handle the advertised amperage. This is the same barrel connector used on the Arduino and other products popular with electronics enthusiasts. It's perfect for powering the Hak5 WiFi Pineapple Tetra when cruising around town or hiding out in an industrial area.

Decent adapter as long as it works. The problem is that the connection is not very strong. If you barely touch a wire or part that goes into the cigarette lighter, it loses power. I added some painters tape to make it more durable. I end up connecting it directly to the fuse box. If you need it as a last resort, this will work, but don't expect a reliable connection.

I gave it 5 stars because of the quality but after ordering I couldn't use it because the end that was supposed to fit my radar detector didn't work because it was too big. They didn't say anything about the different sizes on the receiver side. I'll keep it because sooner or later I'll use it for something somewhere. They should have more information about their product. I didn't even know there were different sizes. It's probably my fault, but still. Good luck and make sure it works before…

It supplies electricity, but buyers should be aware that it contains no diodes or other built-in electronics to prevent electricity from draining your device! In principle, current can flow in both directions with this charger. I was using mine to charge an external battery and noticed that when the car was turned off (was plugged into an extra device, just a cigarette lighter plug) my car radio stayed on and wouldn't let me open the car doors because it was drawing power from the device and…
