Default What is wrong here ?

An electronic travel adapter. Offhand I don't see anything wrong with
it. What's that "House" symbol mean?



** Indicates suitable for indoor use only .


It doesn't carry any agency certification marks, but that's typical
for this class of product, which lives in kind of a legal grey zone.
Typically they are sold in country "A" with a warning that they are
not to be used in country "A". They are then temporarily imported into
country "B" by a tourist (skirting any laws which may prohibit import
of unapproved devices) and plugged in (skirting laws which may
prohibit attaching unapproved devices to the mains). And if it kills
someone it will be in country "B", not the country of sale.



** OK - so you have come across these non-approved and un-approvable piles
of junk before.

This one is made in Hong Kong.


Anyway, I'd guess it to be a "modifed sine wave" inverter with a
switchable voltage doubler front end, sort of like a combination of
automotive inverter with a PC power supply front end. Looks about the
right size for 60W.



** No way - that would be ridiculously expensive compared to a simple
transformer.

Yeah, you're right. It would be nice to have something light though.

Fortunately, most stuff is universal input these days so you just need
a plug adapter. It's been at least 5 years since I've brought a
transformer adapter along.
