Voltage converters are a fairly simple piece of equipment... but that certainly doesn't mean that you don't need to pay attention to quality! Getting the wrong converter, or a poor quality converter, can literally fry the circuits in your appliances. Any damage done by using a poor quality converter would certainly not be covered by warranty, either. Given that it is difficult to tell how a voltage converter is working, it makes sense to play it safe, do the research to ensure you're getting the right model, and to buy well above the bottom of the range for safety.
What type of converter do I need?
If you're going from low voltage appliance to high voltage mains (110 - 220V), you'll need a step up converter. If you're going from high voltage appliance to low voltage mains (220V or 240V to 110V), you'll need a step down converter.
If you're going from a country with 50Hz cycle power to 60Hz or vice versa, you should also get a converter that can change the cycle of power. Appliances with motors may run too fast and burn out more quickly, also appliances with inbuilt clocks won't keep correct time on a different cycle of power.
If you are going from DC to AC power, you'll need an 'inverter', not a 'converter'.
Look for...
When you're buying a converter, look for the following safety and performance features:
* Fuse protection: If there is a power surge in a step-down converter, it can really damage the appliances - fuse protection prevents this occurring.
* On-off switches: These are actually very handy; they help prevent your appliance shorting in the time it is being plugged in.
* Power on indicator: Of course, if you're going to have an on-off switch, it makes sense to have an easy way to tell what it's flipped to!
* AC shockproof sockets: Another fairly essential safety feature
* Durable cords and chassis: You'll want to ensure there is no risk of shock from poorly made cords or structurally inadequate equipment.
* Regulator: Not all converters are voltage regulators, and it isn't always necessary to get regulator. However, if you have an appliance that is especially sensitive to voltage, it can help prevent problems and extend its lifespan by buying a converter that is also a regulator.
* Plug converters included! Of course, this is not an essential feature either... but you can't imagine how many people get their voltage converter in the post, rush to plug in their new appliance, and find forlornly that the plug shapes don't match!
Voltage Converter Brands
Many converters are not branded; many good voltage converters are also sold through small, independently owned websites. You certainly want to buy quality when you are getting a voltage converter, but you don't need to go to a national chain store or find a converter made by a massive multinational to avoid damaging your appliances.
Your best guide to quality in converters is price. Compare the prices from 3 different stores before you buy, and go for a model that is either mid- or top-of-the-range.
