Trigger "Power: Any" doesn't seem to be working on low power USB adapter

[Brian M]

So, for a long time I've been using a tasker setup in my car (does a whole bunch of stuff).  The trigger for this a combination of connecting to my car's BT as well as plugging into power ("Power: Any").  This has always worked well until recently.  After some testing I realized that tasker doesn't seem to recognize when my phone is plugged into a low power (1a, I believe) USB adapter I have that plugs into my car's cigarette lighter socket.  This appears to have cropped up when I upgraded to Android 5.1... that's when I started having the problems.  The strange part though is that my phone knows it's charging (battery icon indicates charging), but Tasker doesn't trigger.  It does trigger though when I use a higher power usb port.

This easily workable as I can just get a higher powered USB adapter, I just thought I'd report the issue.

Sorry, phone is a rooted/unlocked Nexus 5 running Lollipop 5.1

I have a profile that is dedicated to charging the phone.  The profile has a state for power with a source of AC.  This has worked for high and low-power USB cables, both in the car and at home.  In order to make sure it works, I also have it put a clock on the screen and announce it's charging (in case I forgot to turn on the extra power strip).  I haven't tried this with any other states (like Bluetooth) or with any other charging mediums yet, but the idea should be the same.  Hope it helps

Does lollipop still tell you the charging source under settings > power? What does it say when charging with the 1A adapter?

USB 2.0 spec is 5v 500mA (which my phone calls usb), my phone came with a 1A wall charger, and it's my understanding tablets generally come with a 2A charger. So I wouldn't call 1A low power. My phome calls anything much higher than 500mV (AC). My thinking is 5.1 may have added something other than usb/acc.

Good question.  Unfortunately I trashed it and got a replacement, which works very well.
