Bongo Fury

I am looking for something to meter the power consumption of the bongo when parked up and using electricity. Mainly out of curiosity.

Any ideas?

http://www.metermaid.co.uk/metermaid_tech.html is what i have found so far...

Provided you don't want a waterproof meter and can use a 13 Amp socket then, click to take the link to CPC;

I'm thinking here of using it at home, obviously rather than in the field.....
