What could happen with CD player switching on power supply 220v instead needed 110v?


Feeding it with twice the voltage it needs to work on?
In the best case, only a fuse has blown. Worst case? The whole power supply has had a to high voltage, before the fuse blew. All components will be aged and can give up in a few hours, after the fuse is replaced, or in a few months.
It also could be there are already some defect components in the player.

I wish you luck and hope only the fuse needs replacement.

A friend from US gave me hp netbook-1103135- is it 110 or 220v please advise thanks


It most likely has a 110V plug on the power supply; however, all you have to do is buy the appropriate 220v cable for the power supply for your country, and it should work fine on 220V.
External power supplies are designed to use either 110v or 220v -- all you have to do is change the cable or use an adapter and you're good to go.

All our our Panasonic Split Type air conditioners in our plant do not operate when power source is taken from a power generator set but the Carrier brands operates well. What could be the reason for this...


The genset power most likely is 220V line to ground power. You utility power is 220V line to line but uses 2ea 110 VAC line inputs to get that 220VAC. The only way to correct this is to reconfigure your generator connection to 220V line to line IF possible. Some generators that only have a 220V output. Re-configuration is not possible

Measure power at the breaker on gen power as the source and again with the utility as the source. You will see the difference in voltages. Utility power.... each side of the Breaker output to ground = 110V across the 2 terminals 220V

Gen power one side of the breaker output = 220V other side = ZERO.

You can make it work but it would take some heavy duty relays in a power sub paenl so that when the generator is running one side of the power is 220V and the other side is Ground. Once utility power is restored the relays would disengage and power would again be 220 VAC line to line.

You will need a licensed electrician and a PERMIT to install a relay panel such as I mentioned above. Improper wiring of the power relay swtitching panel can cause major power problems in any given installation and trip the MAIN PWR breaker.

Thanks for choosing FixYa.

I wanted to purchase a Bose companion 3 set from the US through ebay. i wanted to know whether they work on 220V and if not how can I make them work at 220V.


Since this unit dose not come with power adaptor. It has direct plug in in to the port behind the sub-woofer unit and other end to the wall outlet. Is there any way to convert the power supply from UK to US (220v to 110v). For example Desktop PCs have a switch behind every desktop unit to change power from 110v to 220v or vise versa.
Anyone has any idea how to make this happen in Bose Companion 3 system.
I bought it from UK and now moved to US and I want it to work in US.
othervise use waltage adapter to use it

You are going to have to replace it....obviously. Here are some places that popped as having the supply you need. I have never used any of them personally.

What is the wattage onroomba 560


The power supply isn't a transformer, its a switching power supply. The power supply is different for different locations, but you should not plug a 110V only power supply into a 220v source or vice-versa. You should contact iRobot if you wish to obtain the correct power supply for another location or to determine if they have an autosensing model that can sense and adapt to either 110v or 220v. You can also use a step down transformer to convert from 220v to 110v. The charger should be using 20W or less, but it will be pulling the current in narrow surges from the peaks of the voltage wave (aka a high 3rd harmomic current) and you will need to use a 40W or larger transformer to avoid unexpectedly overheating the transformer core.
