In my bathroom, I have two cordless devices that charge via USB.

On the first, the LED blinks to indicate charging and is solid when fully charged.
On the second, the LED is solid when charging and blinks to indicate fully charged.

Which is more correct and why? There may be no wrong answers, but two similar devices that work exactly backward from one another has to be some kind of wrong, right?

Are the devices just "similar" or are they identical? (Same mfr, same model?) If the latter are they different software versions? I've never heard of an industry standard for indicating "charging" vs. "charged." And, yes, it would be nice if there were--just pick one & stick to it!

Maybe one of the devices doesn't like the GFCI circuit it is plugged into?

I prefer Red LED for Charging, Green for Charged, Blinking for Something is wrong.

If only one led is available, then my vote is blinking = charging Solid = charged.

blinking when charged is just wrong.

I'm very strongly in this camp. Blinking either means that things are happening or that something is wrong. Solid is completely acceptable for finished. Incidentally, that's how all my power tool batteries charge, in addition to color to help indicate if there is a fault.
