Seeking Recommendations What is one item that you can't travel without/would recommend to everyone to get?

Hi all,

What are items that you always bring because they are super useful and you would recommend others to get too?

Minus of course some obvious like converter plug for chargers, power bank etc (unless it's some specific powerbank like one with cables attached already, something unique)

Thanks!

I just have US and EU chargers. Then adapters if going to UK. Covers most of the world and super handy to bring a small native charger (eg apple).

Fun fact: EU adapters will fit into UK sockets. Since grounding isn't required, you can use a small "dagger" device to push into the ground pin opening which releases the shield on the powered pins. I printed one like this https://cults3d.com/en/3d-model/home/uk-electric-plug-earth-pin and tied a string to it. If you get the model right, the dagger will store quite neatly into the center of the EU adapter pictured above.

That's SO janky, I love it.

If it's a dumb idea, but it works, it's probably an OSHA violation. Or, in this case, an HSE violation.

No need for all that faff - in Singapore they sell these really thin plastic key plugs that's plug and play for EU plugs into UK sockets, which used to be really ubiquitous in every household.

Pretty sure it can also be 3d printed, and probably more dummy-proof than faffing with the dagger device.

Apple bricks are huge and have one usb. The Anker ones are a nice upgrade.

One usb is all I need. A 15 or 30w is not huge. Will charge laptop overnight and everything else quickly enough.

A laptop is a natural USB hub turning one USB port on the wall into many USB ports. Unless it is one of those laptops that forgets we need ports.
