What Inverter?

I'm looking at fitting an inverter to my MoHo, I want a pure sine wave (so I can safely charge my laptop etc) and want it powerful enough to be able to use a microwave for short periods (warm up coffee, cook rice or pasta etc) and wondered if anyone had some sound advice.
My research so far seems to indicate that I will need something about 3000 watts, overkill maybe, but better safe than boom! Whilst these are readily available on ebay and Amazon, I have no idea which device is good and which is a dodgy Chinese copy.
I really would appreciate thoughts from anyone who already has experience of these devices.

I would have thought that 3000W is probably overkill - 2000W seems to be the largest that a lot of retailers sell. I thought that most microwaves were no more than 1200W so I guess you are thinking you would be using other devices at the same time? If you really are thinking that you might be drawing 3000W from your leisure batteries then you need to ensure that you've got as short a cable run as possible between the batteries and inverter plus the appropriate size cables. Also don't forget that whatever you draw from the batteries needs to be somehow put back in again!

I've bought a few things from RoadPro who I've always found helpful. Perhaps better talking to a specialist retailer rather than buying something off Amazon - or certainly eBay?

Agreed that a 2kw inverter will power most microwaves etc. And yes you will need very heavy vehicle starter type cables to the batteries. .. Ray.

If you are wanting to run a m/wave to cook some pasta you are going to need to run it for close on 10 minutes. In order to do that you are going to need a serious bank of leisure batteries !

Personally I think you are being a little unrealistic.

Its not the destination that matters.

It's who you share the journey with (even if like me, itís in a caravan!)
I am very fortunate to have Mrs Plodd to share mine with

Too expensive in reality, ditto for 1200 watt hairdryers, 12v hairdryer works just need patience, or go bald.

I run a 2000w inverter to power up a 800w microwave, bearing in mind that there is a 1200w startup spike that gets it going. However I also have 4 x 90ah leisure batteries and 220watts of solar. It has to be used very sparingly to save stuffing the batteries. What is your battery bank and charging system?

Oh, and itís not pure sine wave. Get yourself a separate 150w version just to use for the laptop charging
