My Aukey 2-port Quick Charge 3 car charger works with the G5. I have had some issues where occasionally it claimed it was fast-charging, but by looking at the battery graph, it was charging no faster than my G3 did. However, when that happens, if I unplug and then plug the cable in again (using either end of the cable), it will usually actually fast charge.
I'm still trying to debug the issue, so about 5 minutes into my drive home, I open the battery graph to see if it's really fast charging. It hasn't happened the last couple of days, but I've been making sure to plug in the phone after the car has been turned on and the car charger is powered. I don't know if that was the problem, but if things continue to work for the next couple of charges, I'll go back to plugging in the phone before I turn on the car and see if it makes any difference.
I may have had this issue with the LG supplied charger, but I haven't used that one much. Usually I plug in my phone on the commute home, even though it's still at 60% and I don't charge it again until I go to sleep, where I use a standard charger on my nightstand.
Anyhow, when I was testing the fast charging with the LG charger a day or so after getting the phone, I ran the battery down, plugged it into the fast charger with the LG cable, and an hour later noticed that it hadn't charged any faster than my G3 would, even though it still claimed it was fast-charging. I swapped from the LG cable to a cable I got from Amazon and then it really did fast charge. From that I assumed that there was something wrong with my LG cable and it wouldn't fast charge, but it might have been that unplugging it and plugging it back in with the same LG cable was all that was needed.
