Regardless of if you want to add more outlets or to add a layer of protection for your gear, you will eventually need to buy a Surge protector power plug (ปลั๊กไฟ, which is the term in Thai).

With a variety of prices and features, not to mention a barrage of vague marketing promises, it is hard to figure out what is worth the money, and what is not worth buying. This article helps you sort it through.

A Warranty on Your Stuff

Some surge protectors offer a warranty on the gear connected to the protector. If your electronic equipment gets damaged by a surge, spike, or lightning strike while properly connected to this power strip within the stipulated guarantee, it will get fixed or replaced by your supplier.

Always Get More Outlets than You Need

You will need more outlets. You will undoubtedly add more gear, without necessarily getting rid of your current equipment.

Use One with Enough Spacing for Big Plugs

Several devices use wall warts-plugs that convert AC power into DC power and look like little boxes with electrical prongs sticking out. Consider getting a surge protector with broader spacing between sockets, or sockets that be rotated or moved, to accommodate chunky plugs.

They Don’t Last Forever

 A surge protector is likely to wear out with time. A few may warn you or outrightly shut off when their protection drops below a safe level. Many will keep working, without protection, and you won’t know it until a power spike damages your gear. If you know you’ve had an electrical event (like lighting blowing out a transformer down the street), it is recommended you replace your surge protector. If you have had your current surge protector for more than a few years, it’s probably worth replacing.
