I am a bit confused... Aquaphor is non-RO system, at least the one that is sold in Malaysia. Are you planning to travel with Aquaphor or just with the pump?

You can get pretty much any pump, example is the link below (NOT MY LISTING) but that would be a hell of a monster to carry around, plus Aquaphor cartridges are not really meant to go through many cycles like that. Do you already own Aquaphor? I'd think having faucet connector for it is a better idea than pump and I would choose different system if you haven't yet bought Aquaphor. Can make it really compact and efficient if you're interested.
