When you unplug the cable you physically remove the power and thereby empty some registers/memory which won't be emptied by a software command.
When you restart and unplug it too soon or too late, that would be the same as unplugging it when it's running. Possibly that might even be worse...
Or am I missing something?
I have a 10000mah model, Homey ran for 14 hours on it.
I'll have to test if you can charge it while a device is connected to it...
But that wasn't really my question. I would like to shut it down properly before unplugging it.
to charge or to be charged....
but not concurrent.
Anyone who knows a Powerbank that supports that please stand up!
For the battery you are correct, the controller electronics should bypass while plugged, switch to battery when unplugged and the charger should provide enough power (current) to charge and feed the homey at the same time.
With specified 2A max for USB devices I think it is possible but not much room for charging as with the ring on Homey uses approx. 1.1 A.
I don't think a lot of powerbanks will support this.
I disabled Homey's idle ledring, so it doesn't use much power actually
It think it's just a protection for the battery because charging it continuously will shorten the lifespan a lot.

Do make sure that the power supply that charges the powerbank, can provide power faster than the device that you're using it for consumes, though!
Just curious
Which is almost the same figure as measured earlier for a Homey with ledring off.
So the big question; did you had the ledring on or ff ?
I'm very(!) positive surprise about the low power consumption of Homey!! (I like low power devices )
Having said that: Technical background: There a filesystems which are automatically recovering from such a failure, using a rollback transaction log like system. If Homey also is designed that file-writes (even to multiple files, or storing in a single transactional DB is also an option) are done in an atomic transaction like way, and the file system itself is auto-recovering, then pulling the plug NEVER is a problem. There are many examples where this is 100% safely implemented. So BEFORE using all kinds of batteries to ensure this, I think Athom should comment on this. @Emile
? (However, using batteries as a UPS to continu working, so not making a power interruption safe, is another purpose and might also be nice.)

The test I did with the battery was just me being a geek. When the power goes, my lights and stuff won't work either, so not much use for Homey anymore then. Unless it can detect the power outage, and warn me about it when I'm not at home
mixed up some things by writing out the "h" and copy/paste....
So it should be;
Thanx!
