We've got one like this,
http://www.ebay.co.uk/itm/Generator-...item2a1d34f686
does the job, not a fancy branded one, not the smallest but it's vey quiet and just purrs away, yep you have to carry some pre-mixed 2 stroke with you to make things easy but it doesn't use a lot, a tank will last a meeting ok depending how many chargers you run from it.
can pick them up new for £80 or plenty of them on ebay for sale by ex caravan owners etc.
