yes that ole power useage again; someone a while ago showed a list of consumption of typical appliances; does any one have the link to this;
also I read; one divides the watts by the power to get amps; so 1000 watt say microwave is 4.2 amps? BUT; what happens if I am not on 230 hook up, I understand the amps will almost double? can someone clarify for me please

Divide the watts by the volts. 1kw heater is 1000watts divided by 230 = 4 and a little bit.

Just use watts divided by 250 or 1kw = 4amps.

Watts is power. Volts is pressure. Amps is the current flow.

Watts = volts x amps.

If you're not on ehu then you will need an inverter and you will use 1000/12 amps = 83 amps/hr + a bit for the inefficiency in the inverter - i.e. probably 90 amps in total. Also don't forget that the start up current will be greater so you will probably need a 1,500w inverter.

Cheers

Majority of Microwaves are 230 volt and 1200 watts and should normally be used on a EHU and will draw up to 5 amps at 230 volts.
It is possible to get a 12v or 24 v Microwave (VERY expensive!) or indeed run a 230 volt one from an inverter (converts 12v D.C. to 230 volts A.C.)But as the microwave is about 1200 watts this means that it would actually draw 1200/12 = 100 amps from a 12 volt battery! Not a good plan!!
So use a microwave on EHU/230 volts of at least 6 amps unless you have large leisure battery (at least 200ah) with a say a 1500 watt inverter.
However cheaper inverters that are not 'pure sine wave' can damage certain electronic devices!
And finally! We have a fitted Microwave but I prefer to cook outside on a £1 disposable BBQ from Lidls!
Shame we have to cook food!

P.s. The jury is still out re efficiency v. power transfer of inverters! Guess a lot depends on price and quality or so Mr Maxwell would have me believe!

Inverters are 90%+ efficient - not 50% as stated in previous post.

All electrical appliances will have their wattage stamped on them somewhere or on a label i.e. a 2000 watt fan heater or a 3000 watt electric kettle etc.

The voltage supply in the UK is 230 to 240 volts. These days, 230 volts is taken as the norm.

A campsite supplies it's power in amps. The average campsite provides 10 amps but some now provide 16 amps and a few still live in the dark ages and only supply 5 amps. You need to ask when booking.

You therefore need to know what each of your electrical appliances will draw in amps and make sure that when used together the total amps does not exceed the campsite supply, otherwise the fuses will trip on the pitch supply pillar.

If you are good at maths you can work out the amps by dividing the watts by 230 (or 240) volts, so, as you say, a 1000 watt appliance will draw 1000/230 = 4.34 amps.

If you take a look at this page and scroll down to the bottom you will see a watts to amps conversion table. Print it off and take it with you. It could be a good idea to mark the amps on your appliances in marker pen so you can see at a glance what they draw but in reality you will probably get used to your own appliances anyway.

Hope this helps. I don't know anything about 12v to 230v converters you will be pleased to know

There is no such thing as amps/hr, do you mean amp hours?
