Charger duo - slight buzzing sound

Explorer

Got my charger duo the other day which I'm very happy about. I keep it in the bedroom for charging overnight and have noticed that when a phone or my watch are on it, there is a slight but still annoying buzzing sound coming from it. It makes this noise whether or not the device on it has finished charging - if one of the charging indicators on the charger is on, it will buzz.

 

Anyone else had this?

Does the buzz still occur when no device is sat on it @ConcreteLlama

 

Even when a device has finished charging if it's still left on the charger it will still trickle charge.

 

Could the buzz your hearing possibly be the cooling fan ?

 

If not then for peace of mind if this was me id try to see if there was a retail model in a shop so I could listen to that one but if that's not possible where you live then see if you can request a replacement. 

 

I've not seen any other posts on forums saying it makes this sound.

@BandOfBrothers Funnily enough at first I did think it sounded like a fan but didn't expect a wirelesss charger to have one - I've got a couple of wireless chargers and none have fans, at least not audible ones. So it may well be that...

Ive noticed it is quite noisy too. There is a slight buzzing but its mostly the fan noise that bothers me at night.

I read on another forum that if you turn off fast charge mode on phone the fan wont kick in but doesnt make a difference.

I love Samsung products.. however this charger is terrible .. I cannot use it at the side of my bed because of the noise it makes. It sounds like fans inside the housing. Extremely disappointing.. unlike the normal Samsung experience.

I'm glad that I found this post. I received my free charger and was extremely impressed with what I saw until i put it by my bed. It is incredibly loud and not suitable for bedside. I thought mine was faulty but it looks to be a design flaw instead. Such a shame as it is a great idea for the watch and phone.

If you turn the quick charge off the phone it stops the fan kicking in .. but I haven't figured out how to do the same with my watch .. think I'll sell the charger ... really disappointed
