220v or 110v power bar / strip for world travel?

I wondered which power rating could be used in both situations. A 110v power bar or a 220v option?

I found the *perfect* power bar. View my review of it!

More importantly, which is less likely to blow up in the other’s territory, frying my bacon while I hibernate?

For a while, I have pondered this question. There are power bars “certified” to work in both 110v and 220v conditions, but they tend to cost more. Mind you, the cost isn’t astronomical as they cost between USD 30 and USD 50.

Two fires occurred near me in the past month, and my power socket was sparking beside me last night. I was thus motivated do some research to understand this, should I be unable to find a power bar that is “certified” for both, or in choosing travel adapters.

I posted the following question on Quora:

I was looking for the difference between 220v and 110v power bars.

According to this web site: Answer to: What is the deference between 110V and 220V?

220v allows you to draw the same amount of power with half the amount of current.

P = Volts * Amps

It cited lower costs as you can deliver half the amount of amps with 220v in thinner cables than with 110v.

While searching online, many people say you need to get a 220v power bar and the 220v power bar works best in both the 110v and 220v situations. Many people say it’s dangerous to plug 110v power bars into 220v power sockets.

However, I would think the *current* is the main cause of fire hazards. Therefore, using a 110v power bar in a 220v socket seems like the safer route as 110v power bars should have thicker wires.

Thicker wires also have less resistance, thus less likely to build up heat. Which thus means less likely to cause a fire.

So which is the correct answer? Which voltage rated power bar can be used in both 110v and 220v situations?

Any help any readers can provide would be greatly appreciated!
