Portable Straighteners

I'm leaving soon and I want to make some rectifiers portable because it is not a socket, so can anyone recommend a decent portable straightening is cheap-ish? Everyone I searched for were to be put in a load carrier which needs a power supply itself is free rectifiers!
Thank you:)

There are laptops that something called a ThermaCell use butane cartridge is not readily available. They last about 8 hours of use of each and you can take with you a little depending on how long you will be absent.
