8. Multiport USB charger/Travel adaptor
Depending on where you are travelling, you will need to buy a travel adaptor if you wish to continue using your electronic devices. It is also a good idea to purchase a multiport USB charger of some sort, to travel light yet still keep all of your digital devices up and running. There are many options available, with an example being this Korjo USB charger which ticks both boxes, featuring 4 different plugs to adapt to various countries, as well as the ability to connect and charge up to 4 different devices simultaneously.
9. Screwdriver Kit
As above, many unforeseen issues can arise while travelling and the need to repair them cheaply and quickly is huge. A small jeweller's screwdriver kit is easy to come across and can help you out of many possible jams, and they are so small in stature they won’t take up the place of other more important gear.
