Will boomboxes marked 240v/220v/110v AC and 50/60 Hz work without a problem on United States power outlets?

Some boomboxes are marked --- (240v/220v / 120v AC and 50/60 Hz)

But I noticed some are marked --- (240v/220v / 110v AC and 50/60 Hz)

Will the boomboxes marked (240v/220v / 110v AC and 50/60 Hz) generally work without a problem on United States power outlets?

Thank you!

Thank you! I did some searches on Google about it, and most of what I found said that it should work without a problem.

But I just wanted to be sure from people specifically with boombox experience here. I appreciate the help. :breakdance:

US homes have a 240V transformer with a center tap that splits it into two 120V legs for your common consumer electronics, but are combined again to deliver 240V to your major appliances like HVAC

But those voltages can vary by +/- 5% or so.
So under normal conditions, your boombox is going to see anywhere from 114 to 127.
Rarely does it drop to only 110V, so I'm not sure why they labeled boomboxes like that.

I think the ones I see labeled (240v/220v / 110v AC and 50/60 Hz) may have been sold originally in Europe.

I've read that Japanese items labeled (100v AC) may not work well in the US, and it is recommended to use a step down convertor between the US outlet and 100v Japanese device.

But thought there is a chance European (240v/220v / 110v AC and 50/60 Hz) items are "close enough". Or that they are United States compatible, and just labeled in a different way than we are used to in the United States.

I have a M70 that has 110V selector. My house voltage is 121 on average. While it's not a clean sound, the amp chip does seem to eek out a little louder distorted sound wide open compared to my 120V models :-)
