Yes, if it is operating correctly. Verify if the cable works elsewhere, I've had that happen a time or two. If the cable is good you may need to check the fuse (I'm not sure which one) or visit the service department.

 

Yes and no. It only provides about 0.5 amp of charge. Many of the larger, newer smartphones require at least 1 amp for a decent charge and 2 amps minimum for a fast charge. If you are using Android Auto/CarPlay, that's all of the charge you will get. I wired in a 2 amp charger just for charging my smartphone using a fuse tap accessory USB plug with two outlets. I have it under the dash so all you see is the cord coming out near the built-in USB outlets.

 

I have the newest iPhone, I can plug it in near low battery, use CarPlay, and have it be mostly charged at the end of most drives over 20 minutes, and fully charged after my 1 hour+ commute. I have never noticed it to be an issue. Your "solution" seems unnecessary for 99% of applications, but more power to you if you want to go all amateur electrician on a new car.

 

Thx. I know the cable is fine. I'll have to plug something else in there to see if anything is flowing.

I never need to charge my phone in the SX but I think I've read on the forum that the ports only
work while the vehicle is on.

 

The basic USB charging rate is 0.5 Amps. Only the B+ and Ground pins on the USB connector are used. The data pins are NOT used. At this charging rate, your phone may take a while to see any increase. The charger that came with your smartphone may charge at a higher rate, but it does this by communicating with the phone over the data pins. Only your phone manufacturer's charger will provide the correct data sequence to enable faster charging. Manufacturer's do this to try to force you into using their charger and not some generic brand.

 

As I understand it, this is true for USB 1.0 and 2.0. USB 3.0 has .9A downstream and 3.1 can go to 1.5A without using data lines. For whatever reason, my smartphone will not charge higher (but maintains a charge) through the car's USB port but will charge up fairly quickly on my external port with 2A.

 

Its not powerful enough to charge the newer phones quickly but given time they will charge. Basically its great for emergency phone power so at least you won't be incommunicado.

 

My issue is that it's not even putting the phone in charge mode. I have to find something to plug in there that will tell me if the port is working or not.

Have you tried plugging into the rear seat port on the end of the console, just to see of that port charges your phone?

 

You can easily find proper usb chargers that plug into the 12volt ports. Fast charge to your heart's content with them.

 

That certainly works if you are not using it for other devices like I do. Besides, I also hardwire my other accessories like radar detector and dashcam which work out of the same circuit.

 

Both USB ports will charge my Galaxy S8 just fine (standard charge rate) but I have a 12v 2-USB that I can fast charge with while leaving my mp3's in the front console port.

 

until there emerges an agreed upon fast charging standard for phones throughout the auto industry we will be stuck with how things are now. This will require the entire cell phone industry to ratify a standard with one of the automotive standards bodies. I somehow doubt it will happen anytime soon, even though everyone would benefit from it, both cell phone makers, and the auto makers.

 

The tech world can't agree on a single USB standard. (I blame Apple.) How can we expect the auto industry which is always behind by a couple of years to even attempt to keep pace. It's possible to rapid charge from a standard USB port. PCs have had this for years now.

Why can't car makers put in a better port?

It's even worse with the wireless charging standards.

Well, we only have the one USB charging port and it's in there front. We only have the round port in the rear.

I plug my phone in the front and it would trigger the charging icon briefly, then stop, then start for a second or two and stop again.

I'm trying to figure out if this USB charging port is broken or not.

You should really try another cord if you haven't. I have had cords that worked great in most receptacles, but would act just as you describe in others.

I have no interest in using them but the new thing is charging pads. I think your phone has to be
setup to charge this way. I've never had problems with my Samsung's, LG's (Android) staying charged
all day. Not saying I've never used the car port but very very seldom.

 

I'll do that next, thanks.

You'll have to forget the USB port as far as charging. Get a stronger adapter and use the heavy-duty cord that came with the phone or similar and you will have quick charging. I have to do the same thing.

 

Thanks. Can you elaborate please? Is it a common thing for it not to charge properly?

There's been a bunch of various responses, but this has morphed into something much more than my original intent. Quite simply, should my USB port on my 2018 Sportage LX be able to properly charge my 2018 version Motorola G6 (Verizon) or not? I've also tried my older Moto Z Play Droid (Verizon), without success. My charge icon comes on fir a second, then disappears. I've tried another USB cable.

I think I've read a post or two that suggest the USB port does not provide enough power to charge modern phones.

At this point I'm still unsure if there's an issue or not.

It sounds like your port is charging. There may be an issue with a known problem with Motorola phones. First check the port in your phone to make sure there is no junk in it. If it is clean, put your phone into "boot mode" by holding the power and volume down buttons for about a minute. When it boots, choose "normal" power up. If that doesn't work, have an audio shop put a meter on your port. If that doesn't work, and you have an auto power port cable for your phone, plug the cable into the 12v outlet and see if that works. If you don't have an auto cable, get a decent quality 12v USB adapter and try that. Amazon has one:

Thanks. I can guarantee there is no problems with either phone. Do you know the amount of current that's supposed to be coming out of that USB port?

What is the service manual saying that port should deliver?

Thanks.

Just because the phone seems to be working correctly, doesn't mean that the charging circuit doesn't need to be reset. A "normal" boot won't harm a thing on your phone. However, the probability that it is a charging circuit issue is rather low, but I always like to eliminate all possibilities when I have an issue -- especially, when it does no harm, takes very little time, and costs nothing.... But it is your call. I don't know what the service manual says, but the original spec calls for 0.5 amps.

 

Thx. My phones get power cycled weekly. Again, I can guarantee that nothing is wrong with either phone.

Half an amp? Why did Kia even bother?


Sent from my XT1635-01 using Tapatalk

 

1. Power cycling is different than a "normal" boot. I'm sure you know that....

2. 0.5 amp is an industry standard based on the USB 1.0 and 2.0 specification. It isn't the car maker's problem, they are only sticking to the specification. If you vary from the spec and then hurt someone's older phone, it then becomes your problem. The USB port is not only used by phones, but by other devices like flash drives that might be damaged by the higher output.

I chose a smartphone with a very bright, HD screen and run a lot of apps in the background. The $12 I spent on a 12v higher output USB adapter doesn't really bother me much on a $600 smartphone. Deal with it....

 

It's pretty simple, the reasons are outlined in numerous posts above, and it's not a Kia problem, it's an all cars for the most part problem.

The solution is a plug in charging cable using a 12 volt port. Pretty straightforward. If you are concerned about using a third party car charger, most mobile phone providers sell brand specific car chargers.

I have no concerns using a 12-v DC adapter. My concern is that I have something built into the car that is unusable to me.

I appreciate all the suggestions and replies.

for Android phones you can use AMPERE app. It will show you in real time what amp are used
