What size of genny would one need to get, that can run a set of tyre warmers, boil a kettle & run a hair dryer? (not all at the same time!

)
Hopefully one that isnt to huge to drag about - would a 720w do?
If not - what should I look for?
I sold my old one 5 years ago which had a push start on it, as I was no longer doing the national equestrian competing circuit.
Ideas/advice please over this w/end (whilst AK is away off racing & wont be able to see this post till Monday when it ought to be buried), as I'm looking to get one in the next week or so. If it could run a set of large hedge clippers too, that would be great, as I could then use it at the stables for field/hedge maintenance
