This charger works great! It's very easy to connect without needing a degree in electrical engineering. It's a simple two-prong connection with a + and -. It illuminates nicely when it is properly connected to a power source, and does a fine job at charging my devices. It charges at a slower rate than your standard electrical outlet in your home, but that is to be expected from any in-car charger.Be aware that if you connect this directly into a "Hot Feed," (IE: Your car's battery or any circuit that receives power when the car is turned off), the back light will constantly remain illuminated. The upside of doing this is that you will be able to charge your devices without having to turn on your vehicle. The downside of doing this is that the back light will be constantly draining your battery, albeit at a very slow rate. It will also contribute to reducing the back light bulb's lifespan. I suggest finding a fuse in your car's fuse box that is only powered when the key is turned to the "ACC" position and using a Fuse Tap,( Pico 0956PT 10 Amp ATM Mini Blade Fuse Add-A-Circuit Fuse Holder ), from which to draw power to this charger. It sounds more difficult than it really is to accomplish. Just make sure that if you do this, that the size of the fuse tap is the same as the fuse you plan to use in your car's fuse box.
