I bought one of these:

in 2009 - very useful for seeing what juice is going through a
particular socket if you want to measure e.g. a fridge/freezer or a
telly. It can give you instantaneous measurements and average over some
period but doesn't store any data.

Well, as long as the supply isn't interrupted you can get total
hours elapsed and total kW used.

Maplin sell that model (L61AQ) for a quid more. However, they're
still selling the equally as good N67FU monitor for £9.99

A quick look at CPC reveals the energenie (PL13062) for £10.05 +VAT
(£12.06), unfortunately as per usual, no great detail on its
specifications.


As it happens, I own an L61AQ (Europeanised Kill-A-Watt) along with a
couple of the N67FU meters which all, according to my trusty Metrawatt
analogue watt meter are pretty accurately calibrated for most loads in
the 1 to 3750 and 3120W upper limit ranges considering the
limitations of digital metering.

I've just noticed that Maplin still erroneously list the power
consumption of the L61AQ as 20W (10W for the yank version) rather than
the more correct figure of 20VA on the Amazon site (the actual
consumption being in the region of half a watt for both types).
