 Posted: Fri Apr 10, 2009 4:22 am Post subject: Voltage differences and potential damage to beard trimmer |
 |
|
I've now had two beard trimmers of 110 voltage stop/not charge. One was an AMerican, and the other was sent from Canada. Neither were dropped, put in water etc. The first one didn't charge fromt he moment it was taken out of the box, and even had a 110/220 switch on it. I'm not sure what the switch was on when I plugged it in, though.
The second one either came fully charged, (unlikely) or was able to be charge the first time, and then subsequently blew something.
I'm confused by this, since it seems highly unlikely two beard trimmers would both have the same problem in less than a 4 month period.
But my two lap tops have no problems with nothing more than a plug adapter, and my 220 korean razor worked fine in Canada with nothing more than a plug adaptor.
Anyone with more advanced electric engineering knowledge than I know what the likely problem is, or is this simply a coincidence? |

| You've pretty much answered your own question. Stop using things rated for 110V in 220V sockets. |

yep.
I have a clipper for hair...이발기 in Korean. You can buy them in those small appliance stores. Prices range from 30 to 100,000 + won. Mine was pricey at 90,000 (apparently 'salon' quality?!) but it still works perfectly after 6 years, so.... |

| You need a 220v to 110v downstepping converter... not just the simple plug. They are sold all over, and are about half the size of a shoebox. You can get smaller ones that would work for a razor. |

It depends. Some AC adapters are rated for 110-220V, 50-60Hz, so they work anywhere in the world as long as you can manage to get the prongs in the wall. You find these on things that are expected to travel, like laptops. |

| Anyone know about using a computer bought here in NZ? Voltage is about the same, 220 or so. Maybe different hertz or so, not sure. |

Most countries are 50Hz, some, like the US, are 60Hz. Here's a nice chart:

While they use the same voltage, New Zealand is 50Hz and Korea is 60Hz. This won't effect most electronics, it can speed up or slow down electric motors or certain old clocks. It's highly unlikely it'll effect your laptop. |
