There are only a few differences between Voltage Stabilizers and Voltage Converters. First, it is important to note that Voltage Stabilizers do the same thing that Voltage Converters do, with one added bonus: Voltage Stabilizers give out a stable output of power from whichever wall outlet they are plugged into. In other words, if you are travelling to a country that you know has an unreliable power source, a Voltage Stabilizer would be your preferred choice. This is because variances in power output can hurt your appliances or electronics. Here in the US, we have an incredibly stable power source, which is why Voltage Stabilizers are not needed in the US. However, in some countries like India, parts of Europe, parts of Russia, and many countries in Africa, the power fluctuates up and down greatly and is quite unstable. So, to fix this problem, a Voltage Stabilizer is needed to give you a stable output of power, no matter how unstable the wall power source is.
These products are the preferred choice of customers who are travelling overseas.
