Portable Air Conditioner High Pitched Noise

The CyberPower UPS started making a high-pitched whining noise. It seemed that the battery had no more life in it so I replaced it with this replacement cartridge from B&H. It is now working again and I hope to get another 5-6 years out of it. It didn't come with a way to recycle the battery so I'm hoping to find somewhere local to dispose of the old battery pack.

This speakerphone is very clear on both ends. Was able to hear the other person speaking clearly even when my portable air conditioner was running in the room.

We have it for everything, Air-Conditioner panel control, Land line phone, Toys Etc',

[This review was collected as part of a promotion.] This is the perfect 3-in-1 charging stand. I’ve used others in the past that have made a very high pitched sound when charging, but this one is completely silent. It charges my phone, AirPods, and watch extremely fast compared to other charging stands I’ve used. It’s also super sleek and looks great on my nightstand!

Placed inline between dbx zonepro 640 outputs and QSC amplifier that was having a high pitched buzz from dirty 120v electric plug. Buzz gone as soon as these were plugged in

Just a wonderful CYC light. We ordered 5 and unfortunately one of the 5 gave off a hideous high pitched screech when powered on. Contacted customer support and they have sorted everything out as our replacement has just arrived. Overall extremely happy with the product.

As always B&H was very quick to send the package out and it was what we ordered no problem. Our only problem is that the air conditioner is apparently too loud for even this windscreen to totally block the noise. It does a much better job but the mic is apparently extremely sensitive to all sound.

I got this because during the hot months I can't run my air conditioner and computer at the same time due to neighborhood brownouts. If I turn the air conditioner off the computer overheats. This covers the outtages so I can work in comfort without unexpectedly rebooting every few minutes. Thanks!

Electrical power spikes occur for many reasons and your sensitive electronics won't survive unless you have a quality surge suppressor. Most products sold as surge supressors only provide a low level of protection and are little more than power bars. The Isobar offers a high level of protection and, unlike most other surge suppressors, will isolate each outlet from surges caused by other appliances plugged into it. Case in point, I needed to use an air conditioner on the same outlet as a computer. The Isobar effectively protects the computer from power surges as the air conditioner cycles on and off.

I ordered my DELTA Max as part of a bundle with the Wave air conditioner. I also purchased a 160 watt solar panel. I live in the south and am planning to use the Wave while camping to cool my tent in the evening. The solar panel will help recharge the Max during the day. I have not yet received the Wave, but I did get the Max and solar panel. I tested the solar panel and Max out today and everything worked as expected. So far, I am very pleased.
