duo charger humming?

[stewarta13wsb]

So along with the September security update for the UK I also received my freecduo charger which is now sitting beside my bed. Question... with the watch & note 9 charging does anybody else's unit make a humming noise? Or does the watch tick - both either or?

i only charge my note and there's no noise. i do notice the charger draws .30amps when there's no device on it. odd.

Is it the cooling fan?

It's the cooling fan, mine only does it when both phone and watch are on at the same time

I've not heard the duo charger hum. Mine is next to my bed and I use it every night
My watch will tick with certain faces but not all and it is very quiet

Mine has a fan, but it's very quiet.

Thanks guys, I didn't realise there was a fan! Where abouts is it?

It's in the desktop stand the phone sits on.

If the phones fast charging is turned Off the fan shouldn't come on.
