I suggest keeping a car travel bag packed that includes the items you need when hiring a car overseas. Some of these items may duplicate things you use in your car at home; I advise getting duplicates and keeping them in the bag because otherwise you will forget to bring them.
My bag has:
- A tire pressure gauge (see a few tips)
- A USB charger that plugs into the car’s cigarette lighter (for instance: https://www.amazon.com/gp/product/B00M6QODH2/)
- USB charging cables for cell phone, iPad, Kindle, etc. (a bit longer than usual, so your devices don’t need to be right next to the plug-in)
- A window mount for your phone, or whatever you’re using for navigation
- An audio cable, for connecting your phone or iPad in those rare cases when the car doesn’t have a USB plug-in (or Bluetooth). I used to have an RCA audio cable as well (for French cars) but these days a USB or standard headphone jack is usually available
- My international driver’s license
- A lucky charm, because, you never know
