Has anyone replaced the USB ports of a 2016 maxima? The two that come with the car barely have enough power to even light up my phone, in fact I lose power faster it seems if I do use it. I'd like to upgrade these ports but can not find any aftermarket upgrades.

 

Are you sure it's not your phone or cable? Never heard of USB ports degrading in power, they either work or they don't.

 

op is right. USBs can be powered or not. Mine would not charge my Galaxy S7

 

I have bought OEM usb charging cables that work with my note 8 and it doesnt work. I asked the dealership about the issue and they say it's just for iPad function or connectivity with devices. Not powered enough to charge phones. I call bs but it is what it is. I'd like to up grade them. Any ideas who might sell a replacement for them?

 

Why not get an auxillary battery to charge your cell phone?

 

The USB isn't powered. It just reads. Replacing the port wont help unless you power it

 

The ports are "lightly" powered. They do charge a simple $39 post-paid type smartphone that I use as a dedicated MP3 player in my '016 Maxima. That phone sits in the car with the screen off and stays adequately charged. But with a Galaxy Note 9 and 10+ I experienced the same as the OP - those ports couldn't even maintain the existing charge level on the phone. I believe Nissan claims that the ports are 5V 1A - but I wouldn't be surprised if they're actually 0.5A per port.

 

The USB ports in my '17 certainly do charge both Apple 6S and Galaxy J7. Just yesterday I did a 200 mile run using Apple Carplay with both Google Maps and MP3 on at the same time. Left with 68% charge and arrived home with 100% charge. The USB's work just as well with the Android, maybe charging faster.

 

yea i have in 18 and mine charges my phone as well as accessing car play. so its confusing when you say USB isn't powered. my USB charges my Iphone...

 

2019 now have USB-C to supply more juice. Higher end models add two rear USB, too (again, one A and one C).
As per the OP (and others), USB-A is barely hot enough to keep it charging - especially when using live maps/navigation through CarPlay.

 

Agree, the 2019s and 2020s offer enough juice to charge most phones including my Galaxy on the USB c ports, front and rear.

 

because I would like for my usb ports to actually be functional.

 

you think the 18-20 would be compatible if I were to fine those?

 

Remember the connector types of USB-A. B and C do NOT specify power capacity of the source but rather just what the cable is capable of sustaining. iPads, S9+, newer devices want 2.0 to 20 amps plus at 5 - 20Volts (quick charge spec/USB-PD) I can't find any quick charge or USD-PD specs on any gen so I assume at best, USB-3 (.9 amp at 5v or about 4.5 watts) but more likely USB1.1or 2.0 (.5 amp at 5v) OK for connecting but not so good with modern devices at charging (especially multiple devices). They will however all allow data transfer (USB Functionality) As some mention, the later versions probably support USB3.0 which allows more and newer devices to actually charge at rates that we believe usable. IF you plug in your phone, tablet, media player,all should be able to play music but not necessarily charge...especially newer devices. Sorry for all the geek speak.

 

I have an iPhone 7 Plus and my brother has an iPhone 11 and both phones charged while doing CarPlay I have a 2016 maxima

 

LOL! Of course they are powered, the main point of having USB ports in vehicles is for charging devices. Now there may be some ports that are unable to transfer data to the stereo depending on the vehicle, but they ALL should have the ability to charge.

 

Exactly, they all can charge, the only question is "How Much" although I don't know about the "main purpose" as I didn't design the car!

 

2017 - USB ports 1 & 2 power/charge everything I have plugged in to them.

Issue: That pos burns through more cables than a 5 year old electrician.

New cable... works great for a little while, then intermittently (charge/not charge) then toast. The cycle has repeated itself a multitude of times.

Factor: Cable quality is def an issue - the poorer the quicker it goes. I’ve also noticed some lightning pin discoloration. Might be my eyes but I swear one of them gets darker than the rest.

Thought: Has anyone actually measured the power output of each port individually? Then through different cable types? Might be interesting to note any differences.

Most Success: Anker Powerline II lightning cables.

 

My 2016 SR charges my iPhone 11 Pro Max and all of my other iPhone devices prior.
