See I knew there was something I wouldn't be thinking. I've found single/double stoves now designed for camping and less than 1500w for upto 2 rings. Also more reasonably priced at £20-35 rather than the first few I saw.
Double stove MKT-200 UK £34
MESTIC Single stove MKT-120 UK £20
I have several gas stoves, but if I'm paying for the EHU for the bikes I figured I may as well look at some other things. Not looking to go overboard though.
Is that good or bad relative to what I initially posted? I checked back on the site and their info just says "EHU" with no mention of restrictions.
