does it make noise when you are charging something?

It should not. Verify that the cigarette lighter socket is clean and clear of any debris and because of the how this unit works the car's engine should be running when this device is in use. The unit really needs 13.5 to 14.5 volts dc to be happy. The car's alternator can deliver that, the battery only delivers 11.5 to 12.0 volts dc max.

Yes but after some time a buzzing starts to emit. Annoying because I have it in my office and don't want to keep plugging in the charge cord.

The charger i received does not make any noises, so hopefully it helps you identify the issue. In your case i would definitely try to get a replacement as this noise usually corrseponds to malfunction. To add...my last charger which i replaced made those noises and aoon after stopped charging. Cheers

I've read other reviewers comments about exactly that, a high pitched whine like a camera flash charging up. All I can say is the one I got is perfectly silent. I keep it on my nightstand and have never heard anything.

I believe it's a malfunction. My charger doesn't make any noises while charging laptop.

Same as if you were plugging it in to charge. If your volume is on it will make the charging beep and light up red. When you remove it no noise.

Mine does not make a buzzing noise. Contact customer service they will get you a replacement charger out promptly. Mine do take a full charge and last as long as the OR battery.

yes it makes a noise. it is subtle but it does make a high pitched squeal that you can hear if you listening for it.

no noises. But I haven't used it for over 2 months and will throw it away. very disappointed. It stopped charging after three or four uses. Perhaps the noise is a good sign??

The noise is a low voltage warning, put it on the charger and it will stopI leave mine on the charger at all times to be certain it is ready to use

Yes you can use this while charging. Depending on the volume, this will result in some static/noise, but I've only experienced this turning it all the way up just to see if there was noise from charging.

Mine does not make noise. If you put it against your ear there is a faint buzz. But nothing to be alarmed about or a nuisance to use.

No. I've owned two of these and they do not make noises unless you touch them while on.

That doesnt sound right. Mine made no noise. Initial charge was 99%. Placed battery in phone and charged to 100% after a couple of minutes. Charges to 100% every time now.
