I just picked this up. Is the charger supposed to emit a high pitched whine while its plugged in and charging?

Not to my knowledge. Mine has never made a noise of any kind. You should contact the manufacturer or Amazon.

It's not suppose to. I checked and rechecked mine before answering your question. You shouls get in touch with Anker's support. They usually give a reply within 24hours.

Sounds as though the charger transformer may be shot, test it with a tester or hold it to your ear see if it buzzes, or feel it see if it gets warm. Check connections also. Assuming of course it is the correct charger for the batteries.JT

Mine works great. You may have a defective charger. I would exchange the item for another one

No, mine seems to be just fine. I have had it about a month and already charged it many times.

Mine have never made any noise while charging, I have two sets and neither do that.

Mine arrived charged and has operated without incident since I installed it. Sounds like you may have a charger issue.

Mine emitted a red glow from the port were the battery plugs in but it never indicated when it was done charging. The directions said it would glow green when it was ready, but it did not. It simply stopped glowing red. I hope this helps. If not, you may need to contact the manufacturer and tell them the issue.

Did you plug it in right? I plugged it in 1st time & it got hot!! Turned charger over & it charged up fine.

I do not think so, at least mine does not do it.. You must likely got a defective unit; just return it and get a new one, it is worth the effort because it is a good charger. Good luck

In my case, I had them replace the charging port module since the sound came back when I put back the original module. They sent me a new one and the replacement fixed the problem.

My charger makes a similar clicking sound in the float mode, which appears to be its normal cycling process. It's holding my batteries at 13.3 volts which is near ideal and is apparently not over-charging.

If this charger makes noise I can't hear it. The device is located on the top of my dresser and the charge cords looped behind to keep out of site.

I wasn't aware of a high pitch whine with the G9X. Mine works flawlessly thus far.

I had this happen to me whenever the speakers were on, charging, and the headphone jack plugged in to the computer. If it is off and only charging, there is no noise emitted at all.

I would recommend a different charger. Mine makes a crackling noise every time I plug it in. It got to the point that I just bought a different one because I was afraid if frying my laptop.

I believe this is normal operation. It did that for me with the original power supply. I think it's just to let you know when it's charging vs. battery mode. Hope that helps.

Did you push the charger plug in all the way? I made that mistake once, thinking something was wrong. Good luck!
