We recently came back from Ireland and I had to figure out the same thing. Our daughters formula comes in a liquid version so we took those for the travel days there and the back. Once we were there I boiled water each day and pre measured the water in the bottles. Then added the proper amount of powder formula when she needed a bottle. I have a container from Amazon that makes it super easy to measure out formula ahead of time when you’re on the go. Also most of the time if you ask a coffee shop for a cup of hot water to warm a bottle they’re more than happy to give it to you. Good luck!
We bought this for our trip! https://www.amazon.ca/Electric-Anpress-Portable-Setting-Personal/dp/B0BC1NQD7Z?pd_rd_w=9FfL8&content-id=amzn1.sym.799469aa-0a7a-4b73-8d57-8ce8c368b932&pf_rd_p=799469aa-0a7a-4b73-8d57-8ce8c368b932&pf_rd_r=5D9CD6A82M13ZMKXMHA0&pd_rd_wg=vOu8N&pd_rd_r=40b9362e-7515-4214-9de1-3b63a91fea6c&pd_rd_i=B0BC1NQD7Z&psc=1&ref_=pd_basp_bia_rpt_ba_s_2_sc
