I'm not 100% sure but I think that the UK Q200s use large bottles with a regulator, so the gas jets may be different from US ones that can take a canister. Check it
The gas jets on both the Q100 and Q200 are just a tube with holes in it. What I'm not sure is whether the mini canisters can deliver enough gas to properly "power" the Q200. Not really an issue for me as I have the 100 when I want to be portable but I may swap the regulators over just out of interest.
