We have a Dish TV Freeview aerialBox T2200 Recorder and although I have looked on the website I have not been able to find out the wattage. Any ideas?

I don't think I can help tell you the watts of this but explaining how it's calculated, you maybe able to get a good indication of what it could be if you get 2 pieces of the puzzle.

Watts = Amps x Volts
Watts / Amps = Volts
Watts / Volts = Amps

(x is multiplication and / is division)

e.g.
15W Bulb 12V, what's the Amps? 1.25A

Thanks for that, Kame. You have reminded me of what I learnt at school 50 years ago.

I looked on the back of the unit and it had the amps and volts displayed. It worked out at 30w which is just what I wanted to know as I want to power it from a 150w inverter and so that should be alright.

Much appreciated.

The amps listed on things is often just a max figure and higher than what will actually be used. Most likely more of a guide to what size power supply to use rather than an actual load number.

I bought myself a cheap watt meter a few years ago, about \$20 I think. Comes in handy now and again.

LOL, that's what husband does.....gives a lecture, and he loves to go on about ohms for some reason. I still haven't learned the ohms...

Recently he asked me how much oil for 80ml petrol (50:1)which led to a lecture on mls etc..as if I didn't know that, I said, cooking involves mls, grams, converting to spoons, cups and back etc...I do it all the time....

next time ask him about reactance , tell him you need to know that for AC , should quieten things down . :-)
(reactance is a bit like ohms for AC , but more math involved )
