Help Car charger problem

[CharlesLewis]

I tried to charge my Galaxy Note 4 with my car charger, but though it said it was connected, it didn't charge. I connected my tablet and it worked fine. Any suggestions? (I had previously posted this in another forum but received no replies so I am hoping it will fit better here.)

Is the Car Charger labeled to handle a 2 amp charge rate?

I have one that I "used to use" on a Galaxy 'S' 5 years ago... IIRC, that battery charged at a 450-500 mA rate?

Anyway, slide forward 4 years and it won't work with my S5 or my Note 4.
I threw it in the trash so it does not get picked up again.

I then found one that stated it would supply 2 amps, and that fixed my problem. Both of them plugged into the normal Cigarette lighter style charging socket.

Thanks. I'll check my charger and see. I didn't realize there was a change.

I am looking at the charger and can't figure out the charge rate. It has "Entrda 10.8-33Vcc 0-750mA" and "Salida 4.75-5.25Vcc 0-950mA" on the charger, which I THINK means it is less than 1. Am I interpreting it correctly?

That appears to equate to input: 10.8-33 volts/750mA and output: 4.75-5.25 volts/950mA. So yes, in a practical sense that's 1 amp allowing for typical =/- tolerances. Makes sense since car electrical systems are based on 12 volts (roughly) and the industry standard voltage for USB versions 1.x-2.x is 5 volts. But looking up the specs on your Note 4 and that has a pretty sizable 3220 mAh battery. So your problem appears to be a less than 1 amp charger vs a 3.2 amp battery. What's the amperage stamped on the side of the charger that came with your Note 4?

This answer is correct:

my! car charger is very old: used it on all my smartphones starting with the Droid x. It still charges my Note 4! I don't understand the technical posts, but the phone charges!!

I bought an Amazon Basics two USB port 12V adapter for my car. Not an expensive toy at about 10 bucks, but I can get a 50% charge on my car ride home (usually about 30 minutes). Just make sure to use quality USB cables with it. I was getting little to no charge with some other cables that I had lying around.
