It is true to say that all electrical appliances require voltage in order to function correctly. The amount of voltage required for each individual appliance or product will vary, based on a few different factors. The manufacturers will usually assemble a product with a certain voltage to suit the country within which it is intended to be used.
This, of course, means that certain electrical appliances will work in one country, but not another. This is where the use of voltage converters and voltage transformers are paramount. Imagine going on holiday and being unable to use everyday items, such as alarm clocks, electric shavers, hairdryers and irons. This list can be further enhanced by entertainment devices such as CD/DVD players and TV's.
In many countries that you may visit, it appears that there is a common voltage of 240 or above. However, 210 Volt devices are now becoming more commonplace in the modern world. These 210 volt devices usually come in the form of high-tech gadgets, gizmos and widgets. Amongst the most common forms of 210 Volt contraptions are computers, radios, video systems that have evolved during the 21st century. By that I mean, you should not expect an old style transistor radio or, even worse, a hybrid of the old Betamax Video recorders!
This really is the cutting edge of modern technology. Two of the most sought after products are the Biostar iDEQ, which is a real high-tech barebones computer and gaming system. The other is the Sangean DT, which is a modern day stellar hi-fi radio.
If you want to know more about these two fantastic devices. You can read about the Biostar iDEQ here or the Sangean DT here.
