- Some time ago I asked some questions about taking a laptop while
- traveling internationally, and I thought I would report back on my
- experiences. Highlight: beware of Radio Shack power conversion kits.
-
- I traveled to Korea, Thailand, and Singapore. In the first two countries
- it looked as if I needed to declare my laptop when coming into the country,
- but the customs people weren't at all interested. In Singapore they didn't
- even ask.
-
- As far as electrical power:
-
- In South Korea, the outlets I ran into were 110/120 volt two-slot polarized
- outlets just like ungrounded outlets in the US. However, my guide book
- claims that S. Korea is slowly converting to 220/240 volts.
-
- In Thailand, the outlets I saw were 220/240 volt dual-mode two-pin outlets.
- They were dual mode in the sense that they would accept either a plug like
- an American two-prong plug (albeit at the higher voltage) or a plug with
- two round pins. The outlets looked kind of like: O| |O
-
- It was in Thailand that I realized my power conversion kit from Radio Shack
- was a worthless piece of junk. The way the kit works is: they sell you
- a bunch to adapter plugs, and then separately they sell you a step-down
- transformer that is supposed to mate to these plugs and provide an output
- which is a polarized 2-slot 110/120 volt output. The problem with my
- kit was that the transformer wouldn't really mate to the adapter plugs.
- (If you try to connect them, they kind of look like they fit, but no good
- electrical contact is made and they fall apart as soon as you stop holding
- them together.) Totally unusable. Caveat emptor.
-
- Fortunately, my laptop power supply will really tolerate any voltage
- from 110 v to 240 v, so I was able to make do in Thailand using a simple
- three-prong to two-prong adapter.
-
- In Singapore, the outlets are 220/240 volt and look kind of like:

- The vertical prong is the ground, and seems to have some sort of mechanical
- safty built in so that you couldn't use a two-prong plug without defeating
- the saftey (which, however, my hosts regularly did). My hosts had one
- relative who died from electrocution. (Apparently the wiring on a lamp went
- bad.) They claim 220/240 volts is considerably more lethal than 110/120
- volts. (Why is North America on a different voltage standard than the
- rest of the world? Is one standard intrinsically better? Which came
- first?)
-
- In Singapore I found that even the plug set I got from radio shack wouldn't
- do me much good because there was no way of converting to an outlet that
- would accept a polarized two-prong plug (still at the higher voltage). Perhaps
- a safety feature, but I was forced to borrow plugs from someone else's (other
- brand, superficially similar) conversion kit.
-
- As I write this, I'm still in Singapore. My girlfriend and I are
- convalescing from some (hopefully minor) tropical disease(s) we picked
- up in Thailand. (I blame the beef salad containing raw lettuce that I
- unthinkingly ate at a restaurant on the pleasant island of Koh Samui,
- but who knows?) Bleah. Fortunately our hosts are doctors...
-
- (Did make it to Malaysia. There I saw a non-functional plug just like the
- ones in Singapore, and a functional plug that looked like
-
- O
-
- O O
-
- i.e., the spacings were like the Singaporean plug, but the pins were round.
- Accepted a plug with two round pins, but only if you defeated the safety
- in the socket for the third pin.)
