I see several reviews by hams - notice noise in your radios when charging? Anyone getting "hash" in their electronics while charging?

I have not noticed a problem with the charge controller. Inverters WILL generate hash, but only in a few places. I have noticed it in the 40-meter ham band.

I only run GPS and VHF and USB chargers all with out a problem. It is keeping the battery at 13.9 volts which is higher than I thought it should be. The water level is staying up so is not being boiled away.

I use mine to charge my trailer's battery when camping. All electronics (phones, Ipods, etc.) are pluged inside into the trailer outlets and we've had no issues.

My Koolpad Qi wireless charger has a different design that the picture to the left. It actually is a stylized "Qi" in a circle. The only sound that I have heard from the charger is a beep when placing a device on the charger. That signals that the device is placed properly for charging. It seems that the coil in the charger needs to be reasonably close to the coil in the device to be charged. I have had the device fully charged and not heard any more beeps. I hope that this helps.

Yes, but i started to hear some noise in my radio stations I suspect its caused by the bluetooth thing, will check

Do you happen to be plugging in a radio transmitter for your music into the inverter. Additionally, check if your phone signal may be triggering the noise, - temporarily shut down your phone and see if you hear the same interference.

Have same radio, never failed. Sounds like an internal wiring glitch...can only be port or the mode switch....either way it's probably unfixable...too bad. You can get a Sharkk speaker for less than $20.00 on net...surprising sound.

the hum level on my pioneer speakers is very low. you can hear a faint static sound if you put your ear right up to the speaker, but it is not intrusive. on the other hand my friend also has these exact speakers, and he sometimes noticed a much louder static noise on his speakers, much like a guitar amp sometimes picks up radio/ cell phone frequencies and those noises come through the speakers. but I think that happened only because somehow his speakers were near some sort of frequency. so it's more of a variable problem, not something that always happens. hope this helps. :)

Hate to say sounds like something wrong. I get the idea. Mine isn't that loud, but there is like an air noise, but doesn't seem to be a bad noise. Or hum, like some I've heard. Mine is more just the "perk" noise.Did you buy it from here. How often used? I'd contact Hamilton beach and ask. Since Amazon is merely the holder, Beach should know more the personality of unit.

I just got mine (Nov 2014) and tried to leave the battery out (to possibly save the battery from being overcharged) - i was disappointed there is an annoying buzz once the music kicks in - it's like the charging circuit wasn't meant to operate without a battery in place :(

I don't think it makes a difference if charging or not, although when using the transmitter you will have to turn up louder than your radio stations. The signal is not as strong as a radio station, just a bit extra volume is all that is needed.

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

No I have not heard it, mine is silent, though I have yet to use it for long periods. I don't think it's normal, but if it still does what it says on the pack it's ok. If it's not broken don't fix it!

My speakers will hum if I have my cell phone charging near them. Do you have other electronic devices near your speakers?

I have never had this issue, and I have owned 2 of these for over a year. Excellent sound quailty. Battery lasts a long time on charge. Hope this helps. I use it with an ipod and Samsung S5. No problems.

Well, let me qualify my response, not unless the 'appliance' you have plugged in to happens to produce a humming sound. For whatever reason that is. LMAO!

The unit needs charged. It will continue until charged. Did it come with a little red plug that you put into the alert or alarm spot on the front? If you have this, putting the plug back in should stop the charger from the high pitched noise. Let me know if this works for you.

I did not hear 60Hz hum or buzz when using my Fuze+. Many other inexpensive MP3 players (eg Panasonic, Cobe) have very conspicuous electronic noise from the unit processor (aka interrupt noise). I find the SanDisks Sansas better shielded from internal noise than cheapter products, but it is not perfect. AC hum hasn't been one of my complaints. Another idea you could try, if you happen to be in a high-noise area, is to get a length of wire, connect it to a metal coffee can and plug the wire into the ground outlet of a three-pronged outlet. That should create a Faraday cage which should absorb that 60Hz signal. I did not hear 60Hz hum or buzz when using my Fuze+.

UPDATE...from my orginal question/post.I decided NOT to use their charging system. Like you Julie I have not noticed any problems. Infact, it is really easy. You take out the rechargables and throw them on the charger. (which also charges quickly) I am already using the charger for the CD player and digital camera anyway!I have been doing the charging this way for almost six months.
