| 1470010 | 2020-07-01 00:22:00 | 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? Your help is appreciated.:thanks |

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 |

| 1470012 | 2020-07-01 01:04:00 | 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. |

| 1470014 | 2020-07-01 02:17:00 | 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. |

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.... |

Your help is appreciated.:thanks Just be aware that the output of your Inverter should probably be Sinusoidal, or you may run into problems. ;) |
