No AC charging - Nexus 7 Q&A, Help & Troubleshooting

After trying a few different roms and yesterday my N7 will no longer charge when connected to an AC charger, it still works when connected to a pc.
I'm using the same charger/cable that has been working for months and the charger works with other devices.
I have tried factory reset/wipes and full reinstall. I have also tried restored backups for a few days ago which no longer work either.
Any one know why it would work from pc and not AC? Could it be a hardware problem unrelated to rom changes?

your tablet charges through PC; are you using a USB slot hooked up to a higher power connector (i know some motherboards have those)

I've worked it out. The nexus AC charger has slide on pins for countries different GPO configuration, the head i had on the charger wasn't clipped in all the way and was causing the charger to work intermittently.

myTouch 3G (original) Interesting USB Brick

Long story short, I flashed to CM6 a while back when RC1 was released and was happily using it for a bit. I encountered a situation that randomly appeared somehow (probably involved using a non-mt3g usb car charger but I don't recall the specifics) where my USB functions did not work anymore.
The phone will not mount the sdcard via usb, adb and fastboot does not detect the phone via usb, and the phone does not charge when "on" but I found out it charges normally when "off" using any charger (official mt3g charger or the usb car charger) and will be fully charged within 2hrs on the 1A wall charger.
I haven't found a solution yet and I've been debating whether it is a hardware/software issue. Any input would be helpful
Oh the headphone/mic attachment works fine as well but that is probably not related to the standard mini usb port/pins since the htc extusb includes pins for audio in/out

[Q] G2 charging problems

Anyone got the same issue?
I cannot charge my G2 via PC or laptop USB. I am using a different cable though.
I've read somewhere that the needed output for a charger to work is 2.0amp, but this is already a USB connected to a computer!
If the charging doesn't work, that means i cannot connect it to the PC at all since it was never detected.
Is it the cable that has problems? This cable that I was using was still working perfectly fine yesterday with my other phone though.
Unless it is usb 1.0 it should only be the cable

computer and car charger not working
Me and the wife have LG G2 from Verizon and our phones will not charge from the computer or using our car chargers. Also, two of my 3rd party wall chargers will not put any charge on it. It thinks it is charging, but it doesn't and the percentage continues to drop. Very disappointing.

I don't know where you got the 2.0 amp from, but it's wrong. The charger that comes with the phone is only 1.8 amps, so you don't need a minimum 2.0 amps to charge the phone. If you plug in a lower amperage cable, you should get a warning that it will take longer to charge and you should use the charger that came with the phone. Haven't tried plugging into my pc yet. I should probably do that now to transfer some ringtones....

Galaxy S5 Not charging from 2.4amp car charger

Hi,
So I just got a new car charger: Xqisit 6Amp Micro USB xqisit.c om/index.p hp?productdetail=20425 (Add the http: and remove spaces as I cant post links yet)
My phone charges fine off the 1 amp port, but when connected to either the short built in cable, or using the same cable as with the 1amp port, my phone does not even detect it is connected to a charger
My phone is a Vodafone Galaxy S5, running the stock 4.4.2 firmware.
This charges fine using any other charger.
We have also tested my dads S5, which is running 5.0 which charges fine using any of the ports.
We've also tested both phones in a different car, and get exactly the same results.
Any ideas why my phone refuses to charge off the 2.4Amp ports on this charger?

Unable to use 3rd party chargers after latest update

Anyone else having this issue after the latest update? I can charge my phone fine with my Samsung adapter and cable, but when I try to use any third party charger (like Aukey), the phone doesn't recognize that it's plugged in and will not charge. I can use the same cable and adapter on my son's phone and tablet, so the cable and charger are fine, but my phone will not recognize them no matter what I do, not even my car charger.

Everything's fine here. In the car, I use the Aukey QuickCharge 2.0 charger & my GS7E charges just fine.

Samsung USB-C Cable is Unique?

TLDR: I am only able to achieve a stable data connection using the Samsung usb-c cable that came with the phone. I've had my S8+ since the first day it was available in the US, Apr 21. And I've had this problem since that day.
Details:
When I plug my phone into a computer (transfer files, etc) or my car (Android Auto), it always works fine with the Samsung cable. It almost never works with any other usb-c cable I've tried, seeming to succeed only if the cable sits just right in the port. If it happens to work, and I move the phone/cable at all, it stops. On a computer, the "you plugged in a device" dialog pops up over and over again really fast (1 hertz).
I've tried it with both usb 2.0 and 3.0 ports on a couple towers and 3+ laptops
I've tried at least 3 different kinds of cables and at least 10 total cables. The cables don't sit loosely in the port or anything. They fit snug and hold fast, as I've come to appreciate about usb-c.
The other cables all work fine with other usb-c devices I have -- Pixel phone, Nexus 6p, Nexus 5x, Chromebooks, Nintendo Switch controllers
Charging works fine 90-95% of the time with other cables. When it fails, it slow charges, saying "Ensure the cable is plugged in properly" or something like that
I see articles online encouraging purchase of all kinds of non-Samsung usb-c cables to use with the S8
I would conclude the port is loose, but the cables all fit snugly, and the Samsung cable *always* works. I don't have to wiggle it in the port or anything--no effort at all.
This hasn't been a big deal for me until this week. I have usb-c cables all over the place I can charge with, and I carry the Samsung cable in my backpack for when I need a data connection. But now I have a car with Android Auto, and want to keep a valid cable in there.
Has anyone else experienced this? I searched around some, but couldn't find anything.
I'm using three different brands of type-C usb cables, micro usb cable+included adapter (micro usb to C). All are working fine.

It's a big I aqh3 I'm 99.9% positive. My MacBook pro power cable is as good as they come but it flaps like 3x then just says fail on my phone screen despite it working fine lol. It does not do this on for example the eng rom for root
I bought 3 type c cables from 3 different manufucturers. Only one of them doesnt work as advertised. Whenever i plug the phone with the cable the humidity sensor is switched on and it tells me the phone port is wet and i can not charge. Cant fidn any logical explanation but thats what i get

I experience the same problem. I haven’t tried the original cable. I just gave up on PC cable cause I never really needed it. I just wanted to use my usb c desktop connector to feel cool since usb c isn’t popular on a desktop yet. But yea constant disconnects unless you plug it without moving it, a slight wind can blow and cause it to disconnect. If the OEM cable works no problem, I’ll just buy one from a4c android store or amazon.
