Nowadays We are surrounded with numerous electronic devices and usually run on a lookout for their power source, it’s important for us to know how to choose a good and safe surge protector? Do the most expensive surge protectors automatically mean the best ones?
When you get a new product, you would see a label with logos such as UL, ETL, FCC and etc. Many people are just confused at the first sight of them and a number of questions bubble up. What on earth do they mean? What are the differences among them? Is any one superior than the others? Although these logos share the same meaning that a certified product has passed certain safety standard, there are still many differences. Let me take HOLSEM products as an example and explain. If you look at the back panel of a HOLSEM product, you will see a well-marked certification label with logos such as UL, ETL, FCC and etc.
When using a power strip or surge protector, we sometimes encounter situations that overload button trips off automatically by itself if the power strip or surge protector has a overload switch. This is the moment that directly informs us that the total rated power is over the maximum power that the power strip or surge protector can handle. In this way, the overload switch will work to help prevent the accident from happening. But sometimes there is also a problem with the overload switch tripping off by itself unknowingly. If we have some devices need to be charged at all time, we don't want the power to be cut off. So, it's better that we can understand the maximum power that the power strip can handle. Then we won't plug that many devices and we will know for sure that the overload situation won't happen.
Power strips basically only provide more outlets apart from the wall with an extension cord - they are merely an expansion of the wall outlets that provides no protection for your devices. That’s the reason why power strips have much lower cost and thus price than surge protectors. Even though some power strips have the circuit break, they don’t provide any protection against the current spikes. On contrast, surge protectors provide protection for your devices from voltage fluctuations, surges, and spikes. Surge protectors have built-in circuitry to catch power spikes and cut off the electricity to the strip before it harms any equipment plugged into it.
For surge protectors, does it matter whether the power cord is thick or not? When people choose surge protectors, there are a lot of factors that need to be taken into consideration. People do pay attention to the power cord to see whether it’s thick or thin, but most people don’t quite understand how to tell if the power cord is good enough for them.
