i looked it up. USB 2.0 port is 5v, the adapter I am using in the car is 12v. The car charges slower. So I am thinking maybe it is the cheap cable I am using. Or else I am way off....I am not an electrician
Not charging on while GPS is fine...just want to get it to charge as fast as when it is plugged into my pc...if possible.
it's NOT VOLTAGE, its AMPERAGE you can have 12v and only have 0.5 amps just as you can 5v and have 5 amps. See the back of the charger that CAME with your device so you can see what i'm talking about.
No.. it is hot as the stove. Burn your finger.. I unplugged out of the lighter then wait for it to cool it off the pick it up.. If I didn't plug it out in time, it may start a fire or get destroyed.
you are talking about the charger?
here's a good analogy, say the wire is a road, the battery a bread factory and the light a super market, the current would therefore be the rate at which the vans leave the factory, and the voltage would be the amount of bread their carrying (the energy). so amps are the rate at which energy is moved and volts are the actual level or intensity of that energy.
Another analogy - You have a big vat full of water. At the bottom is a valve that is closed. The water represents a potential to do work or the voltage. As you open the valve a little bit some water flows out. This represents current. How much the valve is open represents resistance - the smaller the opening the greater the resistance. Now if you had a water wheel near the valve and the outflow of the vat caused the wheel to turn; and if the wheel were connected to a generator you would have a miniature hydroelectric system and could get some work done.
