Hi, how do we sterilize milk bottles when traveling with 6 months old?

I saw this at the baby fair - there are about 2-3 booths at the baby fairs so U can see if you want to buy immediately or wait for baby fair. I bought the portable uv sterilizer for the pacifier but not the bottle - as so far we have not travelled out of SG with baby yet. So u can consider this portable if sterilizer for bottles. It is battery operated. When I am outside, I will use the hot water to rinse through everything. U may also want to think about bringing a clip or something for u to help u hold the thing to rinse or just tahan the hot water?
